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.

You are dumping on Canon, and you went out of your way to speculate on what it couldn't do.

If in this thread, "I [ever] went out of my way", it's in part because you were being overly laudatory in favor of Canon -- i.e. your statement that the MP-E 65 lens was "great", not the "fairly good" that I called it. (And my characterization of it as "fairly good" was reasonable, firmly based on several different tests and comparisons done at closeuphotography.com, with photographic examples there).

But I really wasn't dumping on Canon. The focus-shift-upon-stopping-down issue with the Canon RF 100mm macro is something that just shouldn't be present on a lens that costs that much. A truthful criticism of a product isn't "dumping". And their failure/shortcut there leads a person to wonder where else might they have done an inadequate implementation.

Furthermore, for the focus-bracketing issue, my reference was to Kasson's test on the Nikon Z7, and his conclusion that the focus-bracketing steps of the Z7 weren't close-enough for critical work (as he defined it). Given that, simple curiosity/prudence led to wondering about other brands. If the case with the Nikon Z7, it certainly could be an issue with other brands.

Don't know about you, but when I plunk down thousands of dollars for a camera, I wonder about many aspects of its performance, whether it'll meet my requirements, and be better than what I have now and the current competition. And with many aspects of product performance not adequately documented in user manuals, I don't assume anything.

Over and out.

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.

But I have tested it. And at macro distances. I'm not speculating. I posted results.
