Bryan at The-Digital-Image accomplished his full overview of the Canon RF 100mm f/2.8L IS USM final month, and one of many adverse points that stood out was the main target shift that he skilled with the brand new RF macro lens.

When you solely wish to learn in regards to the focus shift difficulty and see the exams, simply do a search (CTRL-F / CMD-F) for “dangerous copy” and skim what Bryan has found with two completely different copies of the RF 100mm f/2.8L IS USM Macro.

We now have been discussing this difficulty on the Canon Rumors Discord server and one particular person “Tig“, has been speaking with Bryan about this difficulty. Whereas he has skilled it, his points haven’t been as pronounced.

… this was at macro scale, at most magnification (1.4x), so to have this not transfer the topic out of the airplane of focus at f/4-f/8 means there’s very, little or no shift. I’d positively purchase the lens once more if I knew all this. I are inclined to shoot it at f/2.8 when operating and gunning whereas climbing, or at one thing like f/11 – f/14 if doing a little table-top macro factor. In each of these instances, you wouldn’t have the ability to discover any shift.

So the problem might not be one thing all shooters will encounter and it’s doable {that a} firmware replace for the RF 100mm f/2.8L IS USM Macro may repair the shift,
