Even lenses like the 400 2.8 or the 135 or one of the tse or macro lenses?
I'm not trying to be picky but I thought these were excellent optics from canon?
Yes, I would expect you should be able to induce moiré from lenses like these. Just about any half-decent prime should be able to produce mild but visible de-mosaicing artifacts at the image center when stopped down to f5.6-8. Stronger artifacts at wider apertures and all across the frame are indicators of higher optical quality. To look for this, shoot a test subject with high contrast details in a regular pattern with structures approximately 1 pixel wide when viewed in the final image.
Thanks for this information. In a way I hope I forget it, that way I don't...if I can't reproduce it, I've got "junk" lenses, or if I can reproduce it, myc amera is junk. I've got a very flawed way of thinking at times lol.
In another way, it's really cool to learn new things. It's one of the reasons why I love this forums.
