Really great, clear video. Subscribed.

Very informative…Thank You. By-the-way excellent lighting on yourself.😊

Magic Lantern had implemented a good focus stacking method. You focused on the mid-point of your stack and told it how many images were needed in front of that point and how many were needed after that point. It would shoot that number of images (both numbers combined) and you would need to merge the images in Photoshop. I used it several times on my 5D3 and it worked great.

Magic lantern was great period. I would argue that one of Canon’s bigger strategic mistakes was not supporting ML, or at least copying the idea of a scriptable API natively. One of the greatest strengths of open source in hardware like this is that anyone with the combination of programming skills and a desire can come up with a great idea and implement it. For hardware like a camera there are way more photographers that fit that bill than there are engineers at all the camera companies combined.

Thanks ! very helpfull. As usual ;-)

Thanks for these videos re focus stacking, I'm diving into this a bit. Is there an indicator in the EVF and Screen showing if you are set up to take a stack? Also, did Canon modify/improve the focus bracketing limitations explained here in any firmware updates thru July 2023?

Yes, there's an indicator that focus bracketing is enabled. The icon and number of images to be shot are shown just under the images remaining at the top left side of the display. As for modifications or improvements, as far as I can tell nothing has changed in any of the firmware updates since I did this video.

Honestly, given the limitations, I expect I will be doing mostly manual focus stacking.

Are you able focus bracket with exposures longer than half a second with the R5? I tried this with my 14 to 35 and I couldn’t get more than half a sec - so anything longer is under exposed. I was experimenting and trying to simulate / exaggerate with a 10 stop ND filter effect with a sea scape using built in timer.

Sadly, no. The focus stacking mode uses the electronic shutter which is limited to 0.5-1/8000.

I have a question off this subject please. I came over from Nikon to Mirrorless Canons and have a RF 35mm 1.8 and the manual (as well as the lens cap) says 52mm. I have a 52mm Nikon polarizing filter and I cannot get it to screw in on the RF 35. Any advice would be appreciated. Thank you

You've got me on that one. As far as I know everybody uses the same thread pitch for their filter threads. So a Nikon filter should fit just fine on a Canon lens and vice versa. The only place that might not hold true is with drop in filter from super telephoto lenses - but I don't have the experience to be sure here. What I've always done with filters that don't seem to want to start is to point the lens up, set the filter on the threads and gently turn it backwards until you feel the threads fall into place, then screw it on normally.

@@TC_Conner Normally you can use f11 to f16+ with a controlled flash to get sharper picture. They will never give focus bracketing in EOS R. Its Business. Now R7 and R6 mark 2 even have image stacking/depth compositing in the body. You dont have to use photoshop or other software for the image stacking process later. Even R5 don't have that option.. They are giving these options to newer bodies.

Well, it looks like Fuji wins the battle of focus stacking then ;) With the X-T4 (and others I assume) you can set a front focus position and a far focus position and the camera will work out the number of steps required based on the focal length and aperture. I've had everything from 15 images right up to 235 and they stack perfectly in Photoshop or Zerene. It's a shame that Canon / Nikon can't do it in the same way because I'm just about to swap to Canon :p Thanks for the great videos!

Not only can the latest Fuji bodies set a beginning and end point for focus bracketing, you can choose to shoot using a mechanical shutter. Canon forces users to use electronic shutter, which reduces your dynamic range and [potentially] IQ by lowering bit depth from 14 bit to 12 bit. I made the switch from Fuji back to Canon about a year ago. While I don't regret it, I find that in many ways the Fuji OS is more sophisticated than the Canon OS. For example, Fuji shows DOF info on the focus distance indicator. I used this information all the time. I missing having it on my R5. And Fuji allows focus point size adjustment. Canon gives you a choice of two sizes. That said, Canon's AF prowess is significantly superior to anything Fuji has been able to come up with-at least to this point. It's not even close.

@PointsInFocus

No flash will work with the R5's focus bracketing/stacking feature. The camera uses the electronic shutter mode for this operation, and the flash isn't available in that mode. Currently, the only option for an R5 or R6 user is to use a continuous light. R3 users can use focus bracketing with a flash, though it will slow the process down significantly.

Yep, the 24 MP sensor in the R3 uses a stacked sensor architecture. That enables a very high bandwidth link between the sensor and the first level of image processing that enables the sensor's electronic rolling shutter to operate at about the same speed as a traditional mechanical shutter. That in turn enables the sensor to work with a flash with similar timings and operation to any other mechanical shuttered camera.

This is a sad implementation of great feature. Canon kinda blew it on this one. First one of the things that is a no brainer is that this work with flash. This is a huge oversight for macro. Reducing noise, freezing motion in an outdoor shot. I have heard the excuse that electronic shutter is the problem. Ok, use mechanical shutter, this could be fixed in a firmware update, the fact that helicon remote can do it remotely tells me this can be done internally a lot faster.. It won't be as fast but better than using Helicon Remote with is super slow (unless I am not doing something correctly in the settings but I don't think so). This could have been a great feature except as often they do, either the cripple hammer hit it or they have engineers that do not interact with people who actually use cameras and just throw features on thinking they can compete with other camera makers without putting thought into why the feature exists or why it is desirable. Good job Canon.. again.

The problem here, IMO, is that there's always a problem in engineering balancing priorities and thinking through the problems so that you don't do something the messes something up somewhere else. So lets think about the problems here. We'd like the flash to fire while shooting a focus stack. Now I'm going to go out on a limb, and say that in most cases, we also want the focus stack to be shot as quickly as possible. Taking 15 minutes is fine if you're shooting coins on a table in a studio, but if you're shooting outside and there's even the hint of a breeze, time is your enemy. Okay so, problem 1: Triggering the flash. This is probably the easiest to deal with. So the R5 & R6 can't trigger the flash in electronic shutter mode, but they can in EFC and mech modes. So let us pick the shutter mode. The R3 can trigger the flash in electronic mode, so the problem is probably solved going forward. Granted that slows down the shooting speed, but it's probably still tenable. Problem 2: Timing the next exposure with the flash. So it doesn't do us any good if X out of every Y frames is dark because the flash didn't fire. Nikon's solution to this is to let you specify an inter-frame interval. I find that a kludge too, because it's something the camera should do for me, not something I should do for the camera. Plus, as your flash's battery depletes, the recycle time changes, so you have to set something more conservative than you might think. So there needs to be a flash ready signal sent from the flash to the camera. There's been very little published on the ETTL protocol, but not enough that I can say for certain whether that exists in the protocol already. If it doesn't, then it needs to be added, and then flashes would need firmware updates (if they can be) to support it. If it's already there, then it's simply a matter of being able to track the ready state and use that as a condition before releasing the shutter. Problem 3: Flashes cooking themselves. I think this is the real problem at the end of the day. People don't like it when their camera breaks something that its supposed to be designed to work with. With a focus stack, we're asking our flash to fire at potentially full power, as fast as it can, for many, potentially 10s if not over 100, frames. We've already seen the problems with high speed shooting prompting designs like the Canon EL-1 and Nikon SB-5000 to have fans to cool the optics. In thinking about this, I suspect this might be the problem that sealed the deal for the flash and focus stacking. It's not smart engineering or good business, to create a feature that puts another product at risk of damage, as part of it's normal operation. I'm more annoyed by the inability to simply set the front and back focus limits easily instead of having to set the front focus position and guess at a number of frames.

​​ @Points in Focus Humans understand physical limits. A flash will operate only so long, flashes have thermal sensors and reduce firing speed when hot or turn off. If I shoot at F11, then I need less shots but perhaps more flash power. Most manufactures tell you how many shots the unit will fire before it goes to cripple mode. My Godox Ad200 at 1/1 says only fire 40 times with speed light head and 60 times with the bare bulb then let it rest 10 mins. Each step you step down you double the number of flashes. 1/2 power allows 80 speedlight head and bulb 120 and so on until you hit 1000 flashes. If you shoot longer than that without a rest it will set recycle times to 10 second intervals until you allow the unit to rest for 10 mins, then it starts over. My 600ex-rt manual says 48 flashes and it goes into cripple mode. 10 min rest or longer depending on ambient temp. The AD200 has 2 stops or 4 times more power than the Canon 600ex-rt (according to speedlight review) so you don't need full power flash for that flash, the Canon you cannot go past 48 period. (I have never shot the 600EXRT at full power with double diffusion, with a working distance that is less than 12" from a macro subject). The Godox at full power has a recycle time of 1.8 seconds less than a 1/4 second with the same output power as the Canon flash at ful power. My point is. I can manage the flash and buy a more expensive one if I need more power.. We don't need TTL to tell us if the flash fired (though this would be a nice feature but could not be added in a firmware update most likely). So instead of creating a new 75mp sensor to compete with Sonys 100mp sensor. Fix problems in firmware if possible. This is an easy fix. The duration between flashes is easily done as well like the Nikons system. This smells of cripple hammer for product differentiation between the R5 and R3 but I could be wrong

@r1ch m, sorry about the delay, for some reason your comments keep getting flagged for review. > "So instead of creating a new 75mp sensor to compete with Sony's 100mp sensor. Fix problems in firmware if possible. This is an easy fix. The duration between flashes is easily done as well like the Nikons system. This smells of cripple hammer for product differentiation between the R5 and R3 but I could be wrong" First, the R3 has the same limitation as the R5 here, so it's not product differentiation. Which is why I suggested that the real limiting factor is external (e.g. overheating the flash, design priorities, or laziness), not the camera's ability, or inability, to trigger the flash. Second, the engineers designing new sensors almost certainly aren't the same engineers that are implementing things like this in the firmware. I don't see a good argument for Canon not doing both. For that matter, I don't see a good argument to hold back R&D work that requires years to mature (sensor design) to fix or address a software problem that could be dealt with in a man-week or less of development time by a single developer. I mean the kind of thing we're talking about here I could implement, it doesn't take advanced math, it's some if statements and calls to functions that should already exist (e.g. firing the flash, checking for status, etc.). Third, Nikon's solution fo requiring you to manually specify an interval between shots is not really good design either, and should not be emulated either. The only good solution to flash firing while focus stacking, is for the camera to coordinate with the flash through the hotshoe. Forcing the user to do that kind of thing is lazy engineering. Of course, if you haven't sent Canon feedback (at least Canon USA has a feedback form, not all of the other regions do), then you really should. There's never any guarantee that they'll do anything with it, but at least you'll have provided feedback to the company that can act on it.

@@PointsInFocus said "First, the R3 has the same limitation as the R5 here, so it's not product differentiation. " This is news to me. The R3 can sync flash using electronic shutter up to 180th of a second 15 frames per second. It does not have to check with the flash to see if it overhead or if it flashed. So theoretically the R3 could fire a flash when focus stacking without worrying about flash overheating just like it does normally when the user shoots electronic shutter and flash. But if you are saying the R3 cannot focus stack with flash, it is not because of electronic shutter like in the R5 that cannot sync flash electronic shutter So Canon is not restricting the r5 because of flash overheating. It should be able to switch over to mechanical shutter and fire at 12 FPS syncing with the flash if the R3 can do it at 15 frames per second and not worry about flash overheating. I agree the best solution is the camera knows if the flash went off. I think the R5 does know if the flash went of or not because embedded in the raw image. I am probably getting flagged because I have also participated in some political discussions and google hates when you think differently or do not conform to their narrative and world view.

Yes, the R3 can sync flash with the electronic shutter; but it can't/won't do it when the focus stacking feature is enabled. At least that's what the manual says. Page 274, Caution box, 7th bullet down, "Flash photography is not enabled." > "It does not have to check with the flash to see if it overhead or if it flashed." When you shoot in normal continuous drive the camera doesn't consult the flash before it releases the next frame. However, you have to think about the ramifications of the flash not firing here versus when shooting a focus bracket. In normal continuous shooting, you end up with 1 or more frames in your burst that don't have flash. In many, but certainly not all, cases when you're shooting a burst with flash, the flash is providing fill not key light, and as a result the no-flash frames are going to be a bit worse, but they're not going unusable. Moreover, when shooting a typical burst, there's very little frame to frame dependency; we're shooting to get a frame at peak action. On the other hand, in a focus stack there's a frame to frame dependency that can't be avoided; the images have to be combined and the result has to be seamless. If the flash doesn't fire, there's a very good chance that the non-flashed frame ruins the entire stack. > It should be able to switch over to mechanical shutter and fire at 12 FPS syncing with the flash if the R3 can do it at 15 frames per second and not worry about flash overheating. IMO, we should be able to specify the shutter mode we want the stack shot in regardless of the flash or not. The idea of shooting at the fastest possible frame rate is intended to minimize the time taken to shoot the bracket, and consequently the potential for movement and stacking errors. If you're shooting in the field, this is absolutely desirable. That said, it's also clear to me that Canon's vision for this feature was rather limited - probably to natural light landscapes and architectural images. So things like flash sync probably never entered the design brief in the first place. I mean see @Andrew Benbow's comment about Fuji's camera's being able to set the range simply by focusing at the front and rear limits. Again, the best I can suggest is sending Canon feedback requesting the functionality.

What a yawn.
