Hi Duade another great video, using a clear language and a honest approach. In fact I had similar issue with the Canon EF 100-400 IS II. The target (a small bird in a busy background) was just in front of the lens but the camera was struggling to find it. I purposely manually de-focus and try to focus again but it was to late as my beautiful subject was gone. I hope Canon will take a look on this issue because R5 is quite pricy.

Please view my updated video with settings to reduce pulsing. kzread.info/dash/bejne/nmuIp9dqhMrXZaw.html Sigma have responded that the Sigma 150-600C is not compatible with the Eye Tracking Servo mode of the Canon mirrorless bodies. You will need to use single shot AF to get accurate autofocus. The AF will still work in tracking mode but you will get inconsistent focus as I have demonstrated. Cheers, Duade

Hi, Duade. I had/have these same issues. Can I clarify this: in order to use Animal Eye Tracking consistently with this lens, you need to be in one shot autofocus, correct? Do not use Servo focus? Or are you saying that Animal Eye Tracking just won't work consistently regardless because this lens was not designed for this camera?

So pleased that you released this video Duade, thanks for taking the time to do it. I have only had the R5 for a couple of weeks and I am using it with the Sigma 150-600 Sports, both the camera and the lens are on the latest firmware. I was a bit discouraged by the number of soft images despite the Show Focus Point plugin in Lightroom showing the focus dead on a bird's eye. I have learned to cope with the background focus issue as I have just put it down to shooting with mirrorless and I am already getting use to it. I have also been shooting with the Canon 70-200 f/2.8 with a 2x Tele and the focus has been simply awesome. I have the Sigma Dock and as per one of the previous comments I am going to try switching the focus from Speed to Accuracy and see if that makes a difference. At least your video has convinced me that I don't have a faulty R5..Thanks again!

@@Duade Hey Duade just went back out with the lens set to Standard focus via the Sigma Dock. I was chasing Variegated Fairywrens. Southern Emu wrens and Glossy Black Cockatoos and I would say it was about a 95% focus rate out of about 140 pics. Definitely a better rate than when the lens was set to Fast AF Priority. Much happier. Fast AF Focus - Prioritize autofocus speed to reach the focus point as quickly as possible. Standard AF Focus - The default setting achieves both smooth operation and fast AF speed.

Thank you Donald for your expertise. I understand now that I am not alone with this pulsing problem. My old EF500mm f4 has less pulsing than my new RF100-500, both used with an R5. Maybe the reason is that the focus acquisition is slower with the EF500? However, what is incredible with the R5/RF100-500 combo is the ability to follow a small bird like a warbler in focus through the branches of a tree.

Duade, This is the best explanation of the weaknesses mirrorless AF systems that I have found. Thank you very much. I recently switched from Canon 7D Mark ii to Canon R7 and was very disappointed when I took it birding in the forest where my subjects were sandwiched in between background foliage and foreground foliage. My 7D Mark ii could handle that much better. The birds are going to have to sit still longer now if I am going to get their image with the R7. I am learning to use the focus ring which I haven t touched in years! I recognize that mirrorless is the future, but like you I lament this loss in focus capability.

As far as the issue of grabbing a background and annoyingly sticking to it I experienced this. I’ve done some research and it seems to happen on the other brands also. In my case I reported it on a forum and the fan boys were hurling “user error” stones at me for suggesting that a DSLR could outperform a mirrorless in this scenario. Rick Perry has a video on this too where he perfectly communicated that “mirrorless cameras Love backgrounds”. When this initially happened to me I was certain my R5 was defective. Like yourself when I encounter it I often use the ground to bring back focus. Good on you for making this video to help others out who may be new to mirrorless like myself

Hello Duade and thank you for this video. I photograph mostly birds with two cameras - a DSLR Canon 80D with Canon 100-400 L USM II lens and a mirrorless Sony A9 with Sony 200-600 G lens. The AF on Sony A9 suffers the same problems as you described in your video plus Sony A9 is difficult to focus on small or not enough contrasting foreground subjects or horizontal lines which can be frustrating more so that Sony does not have the bird eye feature. The Canon 80D AF is superior in this aspect and I thought it was Sony problem but now I am convinced that this is a mirrorless issue in general. Thank you for your great videos.

A really top notch explanation of an issue I am hearing more and more about and am now noticing in my own shots. I experience lack of focus and hunting with this combination (R5 and Sigma 150-600 Contemporary) when there is insufficient contrast between the edge of the subject of interest and the surroundings. If I then move to something nearby with better contrast, then come back to my original subject, I can take the shot. You mentioned no such issues with the 100-500 Canon RF mount. I have friends who have reported the same issues with that lens as well. And yet your last test with the static parrot had lots of contrast, but still hunted. It is a puzzle. Was hoping the latest firmware update addressed it, but haven't had a chance to test that yet.

I was ecstatic when I acquired a Canon R7 about 5 months ago (moving forward from a T3i and SL1, it was a big leap to upgrading). I wish I found your videos beforehand because I'm struggling so hard with my Sigma 60-600... Some of my photography companions were chalking up my AF issues as a new mirrorless owner, but your videos just helps reaffirm that I'm not going crazy and my frustration isn't unfounded. Edit: Don't know if this will be seen but I just got back from attempting to take pictures of jets (what I typically use the camera for) and it was awful. About ready to return the R7 or downgrade and wait for other lenses to become available... Haha...

I have exactly the pulsing issue with my Tamron 100-400 on R6. The issue reduces a fair bit after I started using BBF but still miss quite a few shots. The latest firmware (version 1.50) improves the situation further but the problem remains.

Interesting. I had similar issues when shooting shore birds with a Tamron 150-600 G2 on an R6. The birds were a good distance away, farther than you were with your birds. The camera kept focusing on specular highlights on the background waves instead of the sandpipers. I had to manually bring focus onto or near the birds before focus locked into them. I eventually got both an R5 and an RF 100-500. In limited use with birds, the 100-500 picked up birds even with somewhat busy backgrounds or low light unless they're really far away.

@@jonzmoviebar7580 since this comment, I've ordered the R7 and I plan to use the RF 100-500 on it. That will provide an effective 160-800mm FF equivalent reach with 32 MP, before adding a 1.4x extender. The 100-500 is so much lighter, faster-focusing, and sharper than the Tamron, it's not comparable. The other thing with the Tamron is that the IBIS jerks when you pan with a R5 or R6. I leave the lens in mode 1 because I have to pan up and down for birds as well as laterally. The jerking makes it difficult for BIF photography and useless for video. Duade's mate Jan Wegener had the same experience. Look up Jan's comparison video of Tamron vs Canon. So if you're shooting motor sports, for example, I highly recommend the RF 100-500 even though it's very expensive. The Tamron is good for static objects but if your subject is moving, it's a pain to use on a camera with IBIS. I also have a 7D Mark II but haven't used it since going mirrorless. My R6 and R5 are way better, both in image quality and dynamic range. The 7DM2 sucks in low light. From what I've read, the R7 is better in low light than the 7DM2 and 90D, though not quite up with the R5 or R6. Rolling shutter is pretty bad though, so I'll likely stick to mechanical shutter.

Hi Duade. Very informative video. I just got fed up waiting for the R7 so I purchased an R5 (firmware 1.4) with EF adapter. With my 100-400 ef II and 1.4X III it is a joy to use, no pulsating focus for my set-up at least. Focus stuck on background happens once in a while though with somewhat very small and low contrast subjects with AF single point focus. You already mentioned in a previous video the different much larger single focus point compared to the size of the much smaller EYE af point; Would certainly help if the single point was the same size and just as accurate as the eye af point. Single point af is much smaller on the 90D. I also own a Sigma 150-600 c with the latest firmware update: I get very sharp R5 images with the lens alone and quite acceptable photos with the 1.4 Canon TC BUT with both set-ups, the focus is slow, often pulsating and so jumpy with the TC it is almost unusable. Too bad, that combo is 840mm but I have to try new tweaks, who knows. I relate the pulsating to the IBIS of the R5 as it seems to improve if the lens IS is set to off. I am handholding so very problematic without IS.

I'm almost thinking of selling my R5 because I shoot birds and have had several issues with the focusing. Even missed a lifer hummingbird because of this on a trip! I end up having to focus somewhere else (on the ground) and then try and focus on the bird again, but end up missing the shot altogether, since birds don't wait around! The sharp/soft focus is a real issue. I feel like after spending this much money on the camera it should work with this lens and not have so many issues. I like many of the features on it, but feel like I'm not getting the results I was hoping for.

It should hold its value very well so you wouldn't lose a lot of money if you weren't happy. The F11 lenses do work well and the 800mm is great for its price but it is very limiting with the 6m MFD, fixed 800 can be too much at times. Ideally you would need a zoom to complement it such as the Rf100-400 which is very light and sharp but lacks weather sealing. Long term the rf100-500 is without a doubt the best option but very expensive. Good luck, Cheers, Duade 👍

thank you so much for this video.

I have had quite a few mirrorless cameras in past few years, now have the R5 with 100-500. The others were a mix of Olympus and Panasonic and the odd older Sony, all of them had similar focus issues like you describe. I just assumed that it is an issue with the type of system, however the R5 eye autofocus is a game changer for me, it’s magic when it works which is perhaps 85 percent of the time. I get over the problem by swearing and giving up, works fine. 👍

Thanks Andrew, yes, the Eye AF is amazing, and the focus issue is a minor annoyance. Cheers, Duade

Thanks Duade. I’ve stopped using the Sigma 150-600C on my R5 because of the pulsing problem. Some days it seems to be particularly petulant and pulses perpetually. Others, not at all. To be fair, I was unaware that there is a new lens upgrade for R compatibility, so I will install that and retry to see if it improves the situation. The 100-500RF back-focus sticking appears to be exacerbated by low light, low contrast, back lighting, or a small subject. Too often I have missed a special shot because of refusal to focus or refocusing delay. Unacceptable really, when you consider the cost of the kit.

Chris, thanks for sharing your experience, good to hear I was not alone in finding this out. I will be checking the lens firmware this weekend and will retest if it needs updating. Cheers, Duade

As I thought about the AF pulsing issue, I realized that it looks similar to the pulsing that you get with a Panasonic camera. Panasonic cameras have only contrast-detection AF; they do not use the on-chip phase-detection that most of today's mirrorless cameras employ. It makes me wonder if the R5 is reverting to contrast-detection when using the Sigma 150-600 and some other adapted lenses. (It could be using phase-detection at first to get the focus close to the subject, and then switching to contrast-detection for fine-tuning, which it does constantly as you keep the AF button pressed.) Thank you for a great video! I personally won't worry about the pulsing since I don't have any adapted lenses. But that issue of a mirrorless camera not being able to find the subject when it's not near the current focus distance is concerning. I wasn't quite clear on your conclusion with this one. Have you experienced this with native lenses, and with other camera brands as well, or is it more of a problem with Canon and adapted lenses?

Hi Duade, I've been using the tamron 150-600 G1 with the R6 for some time now, and I faced the same autofocus issue. When I try to focus on something, even if it's stationary, the autofocus would keep pulsing, and sometimes even going so out of focus it would lose the subject completely and focus on something else. Tamron released a firmware update for their lenses to fit with EOS R cameras but that update seemed to change nothing. It is very frustrating but I've gotten used to manually focusing when the autofocus is too unreliable.

Thank you for the video! The focus on the background is surely an issue. I’ve noticed it on my R5 as well but couldn’t work out why. So I understand that the sensor can’t see what’s under the focus square but it most realise it’s out of focus and should try to refocus. Maybe the focus square/area is not small enough and it’s taking readings from the edge which are in focus? Have you reported this to Canon? Also has firmware 1.5 made a difference?

Greg, yes it appears the camera detects the background is in focus so it stops looking and cannot make out the subject like a DSLR can. I believe Canon are aware of this and It does not appear the 1.5 update helps. Cheers, Duade

Hi Duade, once again a great video. I've had Sigma 150-600 C for a year now and I've been using it with Canon 5D Mark III and I'm very happy with the results. Currently, I've seized the opportunity to rent an R5 for a weekend for free thanks to Canon promotional campaign in my country and I'm also bothered with the "out-of-focus butterfly in the foreground" focusing issue you mention at 9:20. Can't really comment on the issue of pulsing since it's hard to detect with my own eyes, as you mentioned, however, I do hear the autofocus motor going back and forth, but if tested on still subjects, it stops after a few seconds. What bothers me more, however, is another issue that it's not mentioned in the video: when tracking a bird (or anything else, for that matter) on the plain blue sky background using Servo AF with 1-point AF or Spot AF when the bird leaves the point for a fraction of a second and the plain blue sky is in the AF point then the camera loses the focus completely because it tries to focus on the sky and fails. This is very frustrating, especially that I don't have this issue on 5DM3. When using 5DM3 and pointing it directly to plain blue sky it just knows that there's no point trying to focus on the sky and it doesn't even drive the AF motor, which makes tracking the bird on the sky much easier. On R5 it is a nightmare because once a bird leaves the point it takes so much time to refocus that the bird is usually gone. Did you also have this issue? I've tried different settings but I couldn't find any that would prevent from refocusing when AF point is on plain blue sky. On both cameras I have set the setting "Lens drive when AF impossible" to ON (Firmware version of the rented R5 is 1.4.0)

Hi Mariusz, were you using eye tracking or just spot AF? You really need to use just eye tracking on a different back button as once that locks onto the subject such as BIF it does a good job tracking it. Or using wide area with tacking might work better also. It is not perfect and can lose the subject but using eye tracking gives me a lot more keepers than on the 5d series. Sorry to hear you had issues with it. Cheers, Duade

I have the S-150-600mm and us it with a Canon RP. I have found that Oneshot af mode with single focus point (no tracking) works best when Im taking a target that’s not moving much. I use two buttons on the back right to 1) center focus point and then 2) back focus. It gives me more explicit control on idle, small, or far off targets. I still use tracking with birds.

I use the Sigma 150-600 Contemporary on my Canon DSLR as well as my Sony A7r2. I've experienced the same "pulsing" behaviour on the mirrorless body. From what I've observed and read I think what is at play is the difference in auto focus technologies. The DSLRs used USM and "hypersonic" motors to drive groups of lens elements in a linear fashion. Mirrorless lenses tend to use stepping motors driving a lighter single lens element and rely on being able to rapidly accelerate and decelerate that single element when acquiring focus. When using an adapted DSLR lens the motor doesn't have the torque to quickly move and stop the heavier groups so every now and again the lens fails to keep up with the information coming from the camera. Now I suspect when you use the native Canon EF glass on the R series bodies the camera can read that it is using an EF lens and it slightly throttles back the process so the lens can keep up, but with the Tamron and Sigma EF glass being so called "reverse" engineered they are not being recognised by the camera so it carries on as if it is a native RF lens. I've only noticed this phenomena on longer larger heavier lenses. It doesn't seem to happen on lightweight lenses.

I have upgraded the Sigma to the latest firmware while the R5 has been at canon so can’t wait to get it back to see if there were any improvements.

I’ve seen your previous video covering the same subject and have also watched a video on the Wildlife Inspired channel that was posted about 9 months ago where he mentions exactly the same thing using his Nikon Z Mirrorless cameras. He also said sometimes when running workshops he can hear other mirrorless users of various brands cursing when they experience the same problem. In the video he explained that he never experiences the issue when using his Nikon D4S DSLR from 2014 and it works flawlessly. He said it’s like using a massive jump in technology. So it sounds there is still a bit of improvement to be done with AF on Mirrorless. I shoot with a Nikon 500mm PF on my Nikon DSLR and use the focus memory button on the lens which with a press can take me back to a saved focal distance. That would be helpful if it was on the Sigma.

For sony's mirrorless body, instead of Sigma 150-600 Sports, a better choice would be Sony 200-600G lens ($600 more but worth it in all aspects). Plus in sony ecosystem, you can get Tamron 35-150 f/2-2.8 to replace 3 to 5 lenses too which is what I decided to go with instead of buying a Canon R6/R5 & Sigma/Tamron 150-600.

GDay Duade! Thanks for this investigation! I don't seem to suffer for this (R6 + 100-400Lii & EF100L2.8), although it's now too cold in Europe to find volunteering butterflies;-) Nevertheless I learned from it, because in my early urge to preserve battery life I had disabled 'Lens drive when AF impossible'. As a result my 100-400 stopped attempting to focus when nothing was found around the current focus distance. So I had to turn the manual focus to be closer to where I needed to focus and then AF could take over again. It was annoying, but I kinda preferred it over the hunting and sticking to focus on the background which you complained about already in your earlier YT's. Now with the lens drive enabled, I can focus where I want without needing to give a hint via the focus ring, which is obviously better. And so far no sticking to the background but as I said no butterflies to check it completely. In return, I'd like to suggest an extension of the dual back button AF (which I set up nearly identical to you and Jan, and which was a huge gamechanger after upgrading from the 70D where I never liked the back button focus). From another YT, I picked up the desire to sometimes us a zone instead of spot AF for cases of BIF where the bird may be to far away for eye AF. But his suggested method to obtain it was cumbersome. After some searching, I now added the 'direct AF method selection' (on the button right of * aka AF point selection, because I do AF point selection via the joystick) which allows to rather quickly switch between spot and zone.

Nice explanation/video. I program the "AF point" button to "Recall shooting func" , using "Info" button to change settings to only "AF method"=single point, "AF operation"=on (and also Tracking sensitivity and accel/decel to my liking - not sure if relevant). When shooting, hitting "AF-point" seems to get me out of the undesirable AF lock-on. I never need to use the lens focus ring. Originally programmed this way to get focus on partial subject when AF detection doesn't work. Must confess, I've never used a DSLR so maybe I'm missing the point.

I broke down and purchased the R6 which works well with my EF lenses but I also bought 1 RF lens (the 800mm f11). I am actually really happy with the 800 mm. The COST, light weight, size and ability to handhold (very good stabilization) make up for the f11. I am getting more good shots than I ever expected BUT mostly because it is easy to carry around with me on occasions where I would be without a big lens or a camera for that matter and things always seem to pop up. I do a lot of walks in Maine. I encountered the same focus problem (grabbing the back ground) but could not bump the focus on the 800 using the ring, while on AF?? My solution was to set the 1/2 press on the shutter button to spot AF and a back button to eye detection. I was just out trying to shoot Kingfishers in flight and landing with their catch on a perch. I find I can hit the perch with the 1/2 press then hit the back button and it gets the bird fast while on a perch. I am still struggling to focus on the fast flying Kingfisher in flight with eye AF but it's all new to me, so hopefully with practice I'll get something worth keeping.

That was very useful information Duade Thank you for the video I did the latest firmware update and I can see lot improvement already Sigma 150-600mm and r6 Maybe you can test that out 🙂

Paulo, that is great to hear, I no longer have the lens unfortunately, but I think if you know how to overcome the AF issues it can produce excellent results. Cheers, Duade

I work with the EF 28-300 mm on the R5 most of the time and I have the same issue when trying to focus on small objects like a butterfly. After using the focus ring to get the butterfly (almost) in focus the autofocus locks on and stays locked on. Since you didn't have the problem with RF lens, I think we can safely say it's an issue in the communication between the camera and EF lenses.

Charles, unfortunately the RF lens suffers the same background locking issue, apologies if I was not clear with that. It appears to be an issue with mirrorless in general. Cheers, Duade

@@Duade Ah well, no need then to go for the expensive (not available now/sold out) RF glass. Another reason for not going for RF glass is that there's no RF like my EF 28-300 which is sort of glued to my camera. My professional work is providing media with photos and video from fires and accidents. And the last thing you want to do is faffing about changing lenses surrounded by smoke, water spray from fire hoses of in the rain, snow or anything else the weather can throw at you ;-)

When you have the autofocus issues with a zoom lens, try quickly zooming out, focussing, then zooming back in and refocussing. The added depth of field wiwhen zoomed out gives the autofocus a much better chance of seeing the subject, and zooming the lens out and back in is pretty quick. I hope this works with your set up.

This may work with some subjects, however I shoot a lot of small songbirds and they do not allow you the time for this technique. Many times I have gotten a White Breasted Nuthatch framed, gotten instan focus and before I could hit the shutter button the bird was gone. Makes for some good photos of empty tree branches though! lol

Hi Duade. Ever solve your R5 AF problems ? Or good work around ?

Thanks for the great videos Duade. Is it possible that the pulsing issue is related to the IBIS that the DSLRs don't have? Did you also experience the difficulty acquiring AF when switching between subject/background while using a native Canon RF mount lens? I ask because I'm trying to decide between purchasing the Sigma 150-600 or the Canon RF 100-500.

Norman, unfortunately it appears all lenses on the R5/R6 have this background locking issue. To be honest it does not happen all the time and when it does, I turn the focus ring and keep shooting. The Eye AF more than makes up for it. If you can afford the 100-500 it is a beautiful lens. Cheers, Duade

Interesting question about the IBIS. I'm wondering if it is the lens IS from third party not playing nice with IBIS. You might be able to disable the Sigma IS and see if the pulsing stops, that would help at least answer that question...

...and since I just got my R6 yesterday, I can replicate this pulsing AF on my Sigma 150-600 C and I can confirm it goes away if you disable IS or if you go to "One Shot" AF mode as originally mentioned by Duade. Pretty sure this is the 3rd party IS in lens fighting with camera IBIS (in native Canon, they communicate/work together and are linked to avoid under damped response) that then affects AF feedback. I need to see if it is there with more AF points or just spot focus, but likely enough focus breathing is happening to cause the slow(ish) IS movement as you settle on a subject to confuse the camera IBIS.

I had exactly the same focus "pulsing" issue with a Sigma 500mm f4 Sport lens on Nikon DSLR bodies. I put it down to imperfect reverse engineering of the Nikon focus system by the Sigma engineers.

Ketih, thanks for sharing your experience, very interesting. Cheers, Duade

I have constantly had the same issue with the Sigma on my R6. It did seem better after the 1.4 firmware. I haven’t installed 1.5 yet. It is interesting because it doesn’t do in some situations. Birds in flight will generally be in focus. I have gotten 30 or 40 frames of birds in flight without any soft shots. It seems to be more of an issue with sitting birds. Some more than others. It does seem like it could be fixed with firmware but I suppose Canon is n” Ot very interested in doing that. Maybe Sigma could do it. I have seen the 100-500 starting to show up at some US retailers in the past couple of days. Hopefully the store where I have it back ordered will get some soon. If not I may have to go with someone else. My Panasonic G9 has a setting for near and far focus which I have set up on two function buttons on the front of the camera. That mostly solves the butterfly scenario for me. If it is focused too far away hitting the near button will pop it back. I wish Canon would do something similar. Panasonic added it with firmware a while back.

Thanks for your comment, Rod and the info re your panasonic, I thought I had heard this before, that is exactly what Canon needs to help this issue. Interesting your Sigma was doing the same thing. I too have noticed the inconsistency of the pulsing, sometimes it's fine. Good luck on the 100-500. Cheers, Duade

Hi Duade I have the R5 and the Sigma 150-600mm "Sport". I had to settle for this lens because the RF 100-500mm is next to impossible to get here in the U.S. unless you are willing to pay $400-$700 over it's current price of $2,799. (Canon doesn't even have any!). I also have the rf 800mm f11 and I have to say the Sigma is much faster at auto focus and has the versatility. Also, as you know, Canon has a $10,000 gap between the rf1-500 and the other primes! It's rather ridiculous position to put the consumer in. In conclusion, we will have to get by with what we have access to and what is realistic price wise for most people. Thanks for your great content! David Sylvester

David, from the comments in this video it appears the sport version works much better on mirrorless with the firmware upgrade. I agree Canon really are missing that middle ground of lenses. The Sony 200-600 is such a good lens for its price I wish we had the same. I have also wanted a 500 5.6 or 600 6.3 prime that had great quality but was smaller, lighter and cheaper. I guess they need to protect the big whites. Cheers, Duade

If it's OK, I have a second comment. I tried the R5/rf100-500 continuous focus with animal eye. Aimed at a setup perch, it did a great job locking on the birds, even in flight as they approached or departed the perch. When a bird left, it sometimes focused on the background, but then captured the next bird. I doubt if anybody regularly uses continuous AF, but it worked great and it would be good hands-off with a remote shutter.

Kevin, thanks for sharing your experience, Cheers, Duade

Hi Daude. I bought R5 3 months ago and immediately noticed the behavior you have shown. If the focus plane is in front of the object, the camera can acquire focus on the object without problems. But once the focus plane is behind the object of interest and focus is locked to the background, AF can't go back to object. And it does not matter even if the object is contrasty like black and white feathers. I missed several shots because of that already. I am not sure if it is just my presumption or fact that AF point is not sized exactly as it is drawn in the viewfinder and due to that camera could skip to the background instead in some cases. I tested this at least once with woodpecker, tried to focus on black and white feathers (no eye AF). AF point was fully inside body contour and the camera still preferred to focus on the background. This behavior makes me crazy. Regarding Sigma 150-600 lens, I am impatiently waiting if sigma releases 150-600 DG DN lens with RF mount. I am considering it over Canon's RF 100-500 if it will be released by Sigma.

in case of acquiring focus - this is indeed a problem to overcome on R5 and R6. They are way less effective with that than my old 7DMKII. I either use manual focus or the custom ring om my 600 f4. once in focus the AF is sticky as never before...

the pulsing issue is something i fairly recently noticed on my setup... and I'm wondering if it's been something that was happening all along. i have the Sigma and using a 6D body. I've noticed it more since I've gotten better at maintaining a stable shooting platform, where before I probably chalked up the soft shots to my technique. Now, as I'm trying to focus, especially on smaller subjects, it just can't seem to lock and hold. I'm not the type to shoot a ton of photos in a burst, so I've missed plenty of shots due it. I'm also wondering if that was a large part of the problem i had with the Sigma/90d combo that I had (and hated).

Very interesting Duade. Good test & findings presentation. Note however your 5Div test was set at 5pt zone vs the R5 demo with spotAF. Suspect my R5 may have done that ‘pulsing’ with the RF100-500. Will now test for that phenon on a tripod. I have a few shots where the AF shot is not as crisp as expected. I do agree that the 5D (SR in my case) is less inclined to hunt / more decisive but with EF100-400.

Barrett, you could well be right, it is very hard to spot this in the viewfinder, especially at a distance. It wasn't until I used the monitor in 1.6 crop mode that I really noticed it. It's possible servo mode is just very demanding on lenses and they struggle. Cheers, Duade
