Focus Stacking with the R5 (images and tips)

[Praefos]

The R5 does the focus stacking using the electronic shutter which has a maximum exposure of 1/2 second, that’s why!

I'm just seeing it right now :-O

Ok, the cripple hammer is for sure at work here!

That's a lazy, annoying term of abuse used by the hard of thinking to describe a design compromise they don't understand or like. Seriously, the only people who actually use a real cripple hammer are terrorists. They have no part in the engineering process. On the other hand, it can be a useful marker phrase to determine whether a post here is worth reading.

OK, please explain to me why anybody might come to the conclusion to limit the electronical shutter to a maximum of 0.5 seconds?

It might be heat? Image degradation? In what way is it different to the EFCS?

And why does it occure in the Canon R5 and not in the Canon M6 Mark II?

I really don't know. I do a lot of 30 seconds sequences using the electronic shutter on my EOS R, but the whole point of them is that there are no variations between them. Trying to be helpful with a lack of imagination strikes me as more likely than a company with an excellent reputation for reliable cameras with good ergonomics having a special department in the design section devoted to annoying people.

I think so to, but it is really strange and odd. Especially, when I hear, that the EOS R can to 30 sec with the electronic shutter as well.

Anyway, I already sned out an email about this topic to Canon CPS (Germany). They already responded with a tip, that didn't work, and promised to send it to Japan for further review.

But definitely you are doing something wrong with the intervalometer, disable the noise reduction, long exposure noise reduction and set the intervalometer with an interval of 1sec!

Just started a thread for the Interval Timer:

Hi Praefos,

I have the same problem. I have used focus bracketing quite a lot on my former X-T4 (and the old X-T2 after it was implemented with a firmware update), but with the R5's implementation of focus bracketing (forced electronic shutter) it's not useable any more for me in many situations.

Not so much because of the decrease of dynamic range (which is a pity but I could live with that), but definitely because of the implied exposure time limit of 0.5 sec.

Have you had any success since then?

Thanks in advance.

No :/

If I could have the source code, I would implement serveral things differently! Somehow, my step from the Canon M6 to the M6 Mark II felt like 2 steps forth and 1 step back. With the Canon R it feels like 1 step forth and 1 step back.

My only solution so far is, to use multiple shoots function (H+ or lower) and use a stop watch within my mobile.

How does the stop watch and multiple shots function solution overcome the 0.5 sec limitation when focus stacking?

It's a dumm workaround and it's for image stacking.

I just put everything on manual, including exposure bracketing, if needed.

Setting my camera to series exposure. (low interval series shot ... i don't know how it's called).

Using a remote cable intervaltimer, I lock the shutterbutton and let the camera fire away while I've set the stop watch with an alarm function.

After the alarm goes off, I stop the exposure (unlocking the button) or even allow one more exposure, because you always have a small lag between those shots. The lag is quite big in comparison to the usuable focus bracketing function.

Anyone upgrading to the new RF 100mm macro when it comes out? I'm tempted by the increased magnification ratio.

I put my pre-order in the day it was announced. I really like my EF 100mmL, but the extra magnification and faster (should be) auto-focus will be welcome additions for sure
