Beautiful shots. I didn't see any focusing issues. I have the 18-35mm Art on the f/1.8 on the 80D & absolutely love it & this is next on my lens list. Q? I didn't notice any 1.8 shots, mostly 2-2.8. Any specific reason not shooting wide open?

Word is that the 50-100mm doesn't seem to have the reported focus issues reported on some others. FWIW; I purchased the Sigma USB dock & used the Optimization Pro software to Micro Adjust my 18-35mm f/1.8 lens. It took me a little bit to get used to it, but once you get some time invested which it WILL take BTW, you'll get better & faster doing the calibrations. It helped immensely & was well worth all of the effort & time involved doing it for the1st time. I highly recommend calibrating your AFMA w/ the Optimization Pro & USB dock.

Good that you addressed focus issues. Sharpness don't mean shit if the focus is off.

Hi Tony, an update of this review could be very interesting in nowadays with new apsc camera like EOS R7, with eye autofocus tracking, sensir stabilized and higher sensor Mpix. Thanks

I've been waiting for this review for SO long!

Hi Tony, I had the same focusing problem with the 18-35 f1.8 art lens on my Pentax K-3. I would focus just fine in live view but not through the view finder. I used the USB dock from Sigma to adjust it and that fixed the problem. I was very disappointed that Sigma didn't make this lens for Pentax, with that in body image stabilization it would've made it a low light beast combo, but hearing how disappointed you are with it, it makes me feel a little better.

What a fantastic team you both make Tony and Chelsea. I have just started amateur but serious hobby p'graphy, so dropping by on what ever i can to read and learn, and i have been hooked to your videos for the past 2 days. Detailed, informative, raw, and clear cut. No shenanigans and fanboyism and hipster kinda stuff. The sheer amount of info and knowledge you guys share is commendable. Would have taken you for a beer if i was there :)

Had a lot of focus issues on 70d, since i moved to 7d2 its nearly unnoticeable. I use 9 focus point in a group and it rarely misses. I use 18-35 and 50-100 and both work rather well.

Good video. I just love your in depth techie videos on lens and cameras.

Tony, you're awesome. Thanks for all the very informative information that true users are looking for. You really dive into all angles of the equation and put it all together.

I will actually chime in that I experienced something similar with my 18-35 f/1.8 and had a horrible time trying to micro adjust correct it and could never seem to get it right, it felt like it was missing on both sides of the focal plane. However as soon as I ran through a Magic Lantern auto micro adjust calibration on my Canon 70D, it's been locked on ever since in studio, street, anywhere I use it. I didn't have this kind of difficulty with seemingly either side of the focal plane on any of my other Canon f/1.8 or faster primes either and could always find what side of the focal plane it was shifted, so I do wonder if the 50-100mm will behave the same. Once I grab the lens (to replace my 50-150mm f/2.8) I'll update here.

Interesting - and thank you for the review about it. I purchased the 18-35 a couple of months ago and at first I thought I'd made a big mistake. When I started to try and calibrate it, it seemed to have that random back or front focus problem. I was really beginning to despair that I'd wasted my money. But I then made some changes, and it seems to be fine now. I have a 70D, and I remembered that the 70D has problems focusing using the central focusing point at f1.8. So I changed the calibration to use the focus point just to the right - and I also only bothered to calibrate it to infinity and also to the next stage down (about 0.5m). It seems to be fine now. Plus in actual use I have only used it on a tripod, and using the live focus with the touch screen. In doing that the images have been sharp, and focused exactly where I wanted them to be. Maybe this would also work with the 50-100? Of course you used the Nikon version, so I don't know if that made a difference or not.Either way, thank you again for the review - I was one of the ones who requested you do it in the first place so it is much appreciated. I may well hold off on buying the 50-100 to see if there is any sort of way to get around these issues that you found...

Hey Tony I took your advice from your buying guide and found the discontinued sigma 50-150 f2.8 os for Nikon. I was wondering if you have had an opportunity to test it, and what your thoughts are on either having 1f stop vs have 50mm extra reach and image stabilization are. Edit: Also Amazing review as always! Keep up the awesome work!!

I'm looking to film/video band concerts (classical) and recitals. Would this be good on a Linux g7?

Love you guys. Was really interested in this lens but focusing issues and no IS is not what I want for my new D500. Thanks again!

I had this exact focus problem with two different Sigma 18-35mm on 3 different Canon bodies. I was wondering if this lens had the same issue and apparently it is.

7:10 The focusing issue with Sigma lenses is a real problem. I've had to ditch around 40% of shots with my Sigma 18-35. It's so frustrating to take a group of nicely framed shots only to discover half of them are blurry back-focuesd. I recently opted for my Tokina manual cine lens as I knew it'd be a closer focus than the Sigma. Luckily, most of my work is film so it's all manual focusing.

I noticed that too. First, sorry for my english. I have only theorys but i think is because that internal focusing elements moving, mixed with the shallow dept of field make the focus inconsistent in different focal lengths, and different focus distances. I noticed it tends to fail or hit depending that, thats why the usb dock solve my problem, you can microadjust every single focal length trough near to far focus distances. I think sigma knows, thats why make the dock

Mr Yamaki stated that the SIGMA service centres can calibrate the lens to your specific camera body. It is possible to do so with the dock yourself, however, it is one of the procedures that requires a high-level of expertise, so it's better to take your camera and lens to a service centre. According to the LensVid interview, he stated that SIGMA must licence and then reverse-engineer the capacities of CANON/NIKON etc so they keep a stable of cameras to calibrate from, however, each camera is different; a D500 and a D7100 would need different calibration, for instance. If you use the most popular camera for each mount, for each country then you will probably have the fewest problems. Apparently, the new heights of resolution exacerbate this. Contact SIGMA, they will likely have a service centre close by.

I am already subscribed because I appreciate your detailed reviews. Keep up the great work.

Always excellent reviews Tony. Thanks.

Forgive the newbie question... but how could the focusing be a lens issue? Are you saying the focusing motor in the lens is flawed?

i have this lens and i can recommend it. My copy nails focus every time on a D500 body. Maybe they got a lemon.

I use the 18-35 1.8 and had to calibrate in camera but also get the focusing issue but normally I just knock the lens out of focus manually and let it refocus - the lens seems to be lazy when it is close to focus and does not move so a good turn of the focus ring before auto focus normally gets me sharp images. I can only guess the same apply s to the 50-100, I think the colour reproduction of the sigma glass really rocks.

Bought this lens on June 10 and have used it more than any other lens in this 3 months period. It's a beauty and I would say the same about its construction. Cannot agree with the comments about it easily scratching but maybe I just take better care of ALL my equipment. I have used it to capture action, portraits, social events (weddings) and just about everything and mostly at F2. I have it paired with my Sony a6000 via the Sigma MC-11 adapter and the camera and lens have not been separated since the date of purchase. I often use it in poor light - because of its max fast aperture - and I find the results are outstanding. Regarding the focus - this took me a little time to adjust but now I get a high success rate. However, with the MC-11 adapter the auto-focus is not lightening fast but is no slouch and definitely faster than manual focus. I suspect it might focus faster mated directly to say a Canon body. All in all, this is the best lens I've ever handled. Worth noting that I have the Sony a7 mated to the Sony 70-200 F4 but the Sigma results are better by far.

Great review Tony! I plan on getting this and the 18-35mm Sigma.

I have inconsistent backfocusing on my 6D with sigma 35 art... I'm going to try it on a 5D IV and if still same issues I'll have to trade up to 35L or 35LII :(

Interesting added clip at the end. Thanks for the review.

My 18-35 had the issue so I sent it back for re calibration, haven't had a chance to put it through the paces since returned. The 50-100 was the shop model from The Camera Store (probably the same one from the review they did) and it seems to work fine. My hope is that now the m5 has focus peaking, buying that and switching to manual if needed. These lens take great shots so I can't see myself selling, but the focusing is a real frustration that I hope they can fix with firmware. *if* canon and Nikon ever get around to higher mpxl, stabilized sensors, and the focusing issues are fixed, these lemses would age fantastically

How is it now?

Great video, you sir are a master! Tony, what happens when you use an apcs sigma art lens on the sony a7r2 in full frame mode and you can fill the frame with minimal or no vignette (lets say the apsc Art 18-35mm 1.8 in full frame mode on the a7rii at 35mm Focal Length) how many megapixels you get with that combo ?

Great review as always. Sigma and Tamron really have upped their games in the past two years. Despite some issues.

Just a thought on the focus problem I think this might just be an artifact due to the narrower depth of field. Maybe it has something to do with it because of the way the electronics recognize focus to begin with. Your thoughts would be appreciated.

tony. i have been watching your videos for over a year and ive noticed that recently you have upped your game quite a lot. especially the video of smartphones destroying the compact camera business was a masterpiece. keep up the great work tony and chelsea. i was thinking of purchawing the nikon 50mm and 85mm primes. could this guy better them both?

I saw this video because I am considering buying it for my new Canon R7. Have you tried it with the R7? Thanks!

Hi Tony, Long time ago you make a comparison between the Canon 24-105 and the Sigma. Now, with the new Mark IV, Canon released a new 24-105. The question is, will you make a new comparison between this three lenses? thank you Greetings from Italy

Thanks for this review. One I have been waiting for since I heard about the lens. I'm sorry to hear that it didn't hold that great standard that the 18-35 gave. Appreciate your honest review

I own this lens and use it with my Nikon D500 body. At a recent indoor event I used my Nikon 17-55 2.8 with a speed light and a flash bracket and I used my other D500 with my Sigma 50-100 to use without flash. The sharpness is outstanding but I noticed that the focus seemed to hunt much more than my 17-55. This was my first shoot with this lens and I learned to slow down a bit to let it achieve focus. I don't know if this lens will focus fast and accurately for sports.

thank you for this really good review, I bought the 18-35 based on your review of that lens and and was preparing myself to buy this lens but held back till your review, I now have second thoughts, Thanks Tony

Thanks for the review. But would it be the ONE LENS that you would recommend if one is into portrait photography of kids with a Dx body? If not, then which other lens would you recommend?

Awesome video Tony, would you still recommend this lens over a Sigma 70-200 2.8? To be used on a Canon 80D

Great review as always Tony! about the misfocusing problem, did you notice whether the back-focusing/front-focusing shots were related to which focusing points you were using in your camera's AF? I have a Sigma 17-50mm f/2.8. After calibrating the back-focus issue at the center AF point, I realized that the lens consistently back focuses when using AF points on the left side and front focuses with AF points on the right side, essentially forcing me to always use the center focusing points and focus recompose. Disappointed to hear about this len's focusing issue. I was interested in purchasing one.

This is the go to lens for my D500. The only thing I can compare it to is when I was shooting with the Nikon 200mm F2 on my D810. I do not experience as much focus issues as Tony is describing, but I have had a few, but have not found them to be detrimental to any shoot. This is an absolute great lens!

Did you get more out of focus shots since then? I get them 80% of the time on my 18-35 1.8 it's maddening

that's some thing special. this is what a review all about. u gave the both positives and negatives about this lens now its upto us should we go for it or NOT.. Thanks Tony Northrup for this lovely video. i really appreciate that :)

Thanks for the review. Do you know if the focus problem has been solved with the software update?

I appreciate your unbiased views

please enlighten me if i am wrong.. we multiply 1.5 with the mm on lens to get the actual mm in DX format because we r using lens made for FF on DX or APSC but thse ART lenses are specially made for DX or apsc so shouldnt we avoid multiplying thm with 1.5? in fact i assume we are suppose to divide the mm on these apsc lenses with 1.5 to get FF equivalent measurement but since the ff is bigger than apsc we r getting vignetting....

I have been using it for events and wedding and so far it has been amazing..I use D7200 nikon

Hello Tony and Chelsea, nice review! I always appreciate your honesty when comes to reviews, always follow your videos here on KZread, they're helping me to understand and make better decisions on the photography world, thanks for the content. Well I'm facing a big problem with APSC lens for Canon, I have a 80D (I know it's not the greatest for video but it's what I'll have to work with for a little while -> just bought it). Every "good" lenses that I see around doesn't have IS and the ones who have it doesn't seem to work well with constant focus like the Sigma 18-50mm (I need to take advantage of Canon's good focus at some point), my best option are getting either get L series with IS (that I know it's not as good in an APSC as they are in a full frame camera) or to get the kit lenses that I'm trying to avoid (I have Sigma 10-20mm f/3.5, Canon 85mm f/1.8 and 55-250mm f/4-5.6) . Do you guys have any advice? I'm looking for something to cover my gap between 20 to 85mm that have IS because I'm planning to do videos but I need to be able to do something hand hold. Thank you for your attention!

I have a Nikon D500 with a sigma 18-200 f3.5-6.3 and a Nikon 50mm e (manual Focus) I Need a variable lens that does a lot for the price, should I upgrade to this?

Think this will pair nicely with my 90D with the 32.5 MP. Tony, can you do a video with that combo?

Hi Tony, How would you compare is to the Sigma 18-35mm? Does that lens also miss focusing too? I'm interested to know as I am thinking to purchase the Sigma 18-35. Thanks :)

Tony, thanks for the review! I am looking for a new replacement for my 28-105mm canon EF. I like it but it is very soft and not sharp. I noticed that you have a 24-105 Canon L at f/4, would you say that would be a good replacement to get tack sharp? I had a carl Zeis 85mm and had to let it go but it was my go to for sharpness. I want to find a good replacement for portrait/over all use on my Canon 7d which as you know is a crop sensor. Any suggestions?

Great review, Tony, really helpful.

I once had a Sigma 30mm f/1.4 with also back and front focusing issues. I remember I read somewhere that this issue is due mainly because of the f/1.4 shallow DoF and any little movement you do between the moment you focus and the moment you take the shot ruins your shot very very easily

hello tony & chelease, what would you recommend, sigma 70-200mm f2.8 HSM II (non-OS) or the canon 70-200mm f4 non-IS? ill be using it shooting very fast paced triathlon most of the time...

Yes I entirely agree my Sigma lens 18-35, I sold it last year I could not put up with the Miss focusing any more even though I had the adapter to micro-adjusted it still would never ever work properly and I got so fed up with keeping my fingers crossed hoping it where would focus correctly to such an extent and I was taking more shots than necessary in order to hope that one of them would turn out, many thanks for all of your reviews Dave Newby

Cool review. Ive had this lens for several months now using a canon t2i and I experience focus problems a lot. The super shallow dof can be great but its also somewhat of a burden. I feel this is because I'm somewhat of an amateur photographer too though. If canon or sony released a higher pixel apsc type camera id be on that like wildfire.

Hey tony, which would be the most bang for the buck...the sigma 5mm 1.4, or this the 50-100 1.8? Thanks -isaiah

So far I'm loving this lens on my Nikon D7100. So far I've taken a few hundred shots and I've had no focus issues. Either I've been lucky or a got one of the good lenses.

I have nikon d7100 I lookin the good lens ara you recamand this lens

I have the sigma 18-35 and when I got it it was front focusing significantly. I spent a while with the usb dock calibrating it (calibrating it involved making adjustments at 4-5 distances at 4-5 different focal lengths). In doing this I found that the the amount of front focus depended on both the focal length of the lens and distance to the subject so just a micro adjustment alone would never have fixed it.

Having pretty much same issues with the 18-35. For pictures, I use live view, and the dual pixel af on the Canon 70d helps. It's a workaround, but not being able to use the viewfinder really cuts down on the speed and fun. Great lens for video, however, and I still plan on picking up the 50-100 because of that.

I've been looking and weighing options for a 70-200 f/2.8 crop sensor equivalent lens. I prefer some type of VC, IS, OSS but am having a hard time finding something that has the right bang for the buck. I have a Nikon D500 and am not afraid of buying used and to be honest, for the price, I can find a used Nikon 70-300 f/2.8 VCII at a decent price compared to something like the Sigma 50-100 or a Tokina 50-135. Do you have any suggestions?

Great videos, thanks a lot .. but if i may i have a question concerning the f 1.8 .. i have watched many of your videos like the one on using a full frame frame lens on a crop sensor body and the sigma 18-35 1.8 review aaaaaaaaand i am confused, "do we have to multiply the f 1.8 by the crop factor when using the sigma lens on a crop sensor body???!! ". "i.e. is the aperture truly at f 1.8 or at f 2.9 equivalent ??!!" i mean it is a crop sensor lens made for a crop sensor body; and don't get me wrong, i understand why we have to multiply the focal length by the crop factor. However i don't understand, do we have to multiply the aperture of a crop sensor lens (as an efs mount lens) by the crop factor or we only do that in case of using a full frame lens on a crop sensor body ??!!!

I have focusing problems with 18-35 on 70D, but I get around that by using it only in live view mode. How would this 50-100 work with live view focusing and would it be the same for all mirrorless cameras?

hi Tony one question...hows the image quality ,sharpness,contrast,bokeh quality with Nikon d500 with sigma at 100mm 1.8 with d750 or d810 with Nikon 70_200 at 150mm 2.8 aperture ...plz let me know...i# this DX combo match this deadly fx combo....

I got this lens too and I use it with Panasonic GX8 and metabones 0.71x speedbooster. I also experience lack of I.S problems but the focus was never a problem for me.

Tony, now that Canon M6 mk2 and 90D has 32mb sensor, please test this lens again, thanks

Hi Tony, I shoot on a Canon 70D and often rent the Canon 70-200 2.8 IS for indoor event photography. I’d like to stop renting and buy a lens for this purpose. Should I go with the Sigma 50-100, or the Tamron 70-200 G2? On one hand the Sigma may be sharper since its built for crop sensor cameras, on the other hand the Tamron has that incredible image stabilization and longer reach. Since the indoor events I shoot are often dim, I’m leaning toward the Tamron. What do you think?

Is the focus problem for auto focus? What happens if you manually set focus?

Samsung's NX-1 and Pentax K3 II could possibly get more out of this lens

Hello...have you done a review of the Nikkor 1.4 12-24 wide angle that is available please...thanks

Tony, I am considering this for my d7200 but the focus issues terrify me. I was curious, as I use single point AF, and most always only use the center focus point, was your focus issue with the center point, or the other points? I have heard the focus issue is mostly with the non-center points, which if so, would not be an issue for me. Was curious yours (or any other users) thoughts on this. Appreciate any help!

Thanks Tony been waiting for this info for a long time. Sorry to hear about the focus issue. Sounds like maybe I should be content buying the 50mm 1.4 ART.

Hi Tony, I am Planning to buy a portrait lens. But I want to do some landscape and general shooting as well. I am a nikon user and using a crop body. Currently I am too much confused between sigma 50-100 f1.8 and Sigma 18-35 F1.8. Although these are quite different type of lens , covers different perspective, but If I want to choose between the 2, which one should i Pick? I am bit concerned for the focusing issue that you mentioned for 50-100. Thanks for your help in advance Annoy

would you go for the sigma 50-150 2.8 with os or for the 50-100 1.8 and crop if you need the extra reach because its so sharp?

If I’m looking for a portrait zoom for APS-C what would be your recommendation then? If not this - do I make the jump to a full frame lens? I would like to upgrade to full frame body but I’m not sure it’ll happen sometime soon. Any insight would be appreciated. Thanks!

I have had some focus problems as well. I still really like the lens because more times than not the picture comes out really good.

Thank you so much I learned alot about my Pentax K5 which has the same dials as well

I am a very new photographer, started off with an APS-C DSLR. My question is would you recommend I buy a 70-200 f2.8 instead then, eventually I do want to go full frame but that's a ways down the road. I don't have a set style of photography, I shoot anything and everything to increase my versatility.

Also, what are your thoughts of pairing the a6500 with the Sigma 18-35 1.8 & the Sigma 50-100 1.8? Does adding the image stabilization in body change your views of these lenses.

At the time you made this video sigma did have the mc11 for sony? because you did not mention it, and tody with the new a6500 this lens is kind of a must. Maybe you can do a second part with this lens on the a6500??

btw about front focusing/ back focusing issue on Sigma - try it on Sony mirrorless. Seriously. I had a similar issue with BF on my Sigma 35/1.4 art on Canon back in the days, but that lens working on Metabones with Sony A7RII seems doesn't have that problem. So try it out, might help.

I agree. so many people blaming the lens and even sending then back thinking they are flawed when its likely the camera body tollorences not being good enough and the pdaf being f5.6 or in better cameras a few f2.8 spots not being able to see the true focus point of the lens. the 50-100 is awesome on my a7ii.

Tony and Chelsea, Thank you for this review from 2016 and your KZread page! I'm new to trying to do serious photography, so this question might sound ridiculous, but, in regard to the focusing problems with the 50-100, I wondered if its inconsistent focus isn't the lens's fault, but the camera sensor? The reason I ask is you mentioned in the video that one of the weaknesses of the 50-100 is that it is "ahead of its time" (2016) because there weren't aps c cameras that had sensors greater than 24mp that could fully take advantage of the lens's ability. I recently bought a Canon M6 Mark II and many of my old lenses didn't perform well because the 32mp sensor was outperforming the lens. I bought a Sigma 18-35mm with a M to EF adaptor and I feel like I found the lens meant for this camera. Would cameras like the M6ii and the 90D, due to their 32mp sensor, naturally resolve the focusing problem because its sensor can better handle the potential of the lens? Thought it might be an interesting test for the two of you to do! Thanks!

What would you recommend to replace my 24-105 F/4? I like to take concert photos and f4 is just not fast enough for low light. I usually end up using my 50mm or 85mm primes (switching lenses with a crowd of people shoving you is no fun). What is something I can grab that won't break the bank? I shoot on a 5d3.

Have you tried the lens on a D500 with the sensorstabilisation? @Tony & Chelsea Northrup

I’m looking for a lens for portraits like this. I have a Nikon. What lens would you recommend that gets similar results? Thanks

Great review! I'm going to purchase this lens and the sigma 18-35mm f/1.8, I also checked out that review. Can't wait!

is the focussing issue with sigma f/1.8 50-100 because the camera doesnt have f/2.8 luminous flux ?? could this be the reason??
