I wouldn't make that assumption. I've never tried extreme macro, but do you think 999 steps is enough?
999 steps on which interval? 999 one micron steps for 1mm depth, by example?
Exactly!
@ThrillaMozilla
Pay attention to what I actually wrote. I said "not fine enough steps", NOT "not enough steps". Not fine enough steps is a different issue from how many steps (though the issues are connected). And the former is what I questioned -- for any brand.
I actually own one of these cameras, and I have used the feature in question. It's actually fine at 1:1, although I haven't used it at higher magnification.
... Jim Kasson ...has examined focus bracketing in the Z7 (among others -- though not Canon, as far as I know) and said that he thinks that "the minimum step size is too large for critical work"....
But he didn't make any measurements on any Canon cameras, did he?
No, he didn't, as far as I know, he's not using and hasn't tested Canon. And you'll note, I said that my question applied to any brand, so I'm not dumping on Canon, it's a potential problem with any brand.
I appreciate that you said that you didn't notice any problems with focus-bracketing step-size on your Canon. But unless you ran the same detailed tests that Jim Kasson does, what you did or didn't notice is no guarantee. With the Nikon Z7, plenty of people were satisfied with the results of its bracketing algorithm, Kasson didn't say that people weren't ever satisfied with the results, he said, based on careful testing, that the step size was too big for critical work.
