Thanks for sharing. I am using the EF100 mm f2.8L macro and am eager to try out the RF version. I’ll probably rent at some point.

The SA business cost Canon a sale to me. I'll use my old EF until it dies and see if there is a better option by then.

I just never use the SA and keep it locked off. I do like the 1.4x:1 mag level. The lens is fast and sharp. the focus shifting issue is a non problem for me. I shoot at f/2.8 when focus stacking anyway.

So, do I understand you correctly that the rumored focus shifting is a fact but that you just don't care since you only use f/2.8? I shoot live insects often at f/11 so focus shifting is worse than no contacts making the 2:1 manual Laowas (90 or 100 in RF) a better choice. The rumors and the SA feature were enough for me to avoid the Canon lens. To get best use from focus bracketing macro, it is best to have both closest focusing (1.4-1 was appealing, 2:1 would be better) and electronic autofocus so the Laowa 100 in EF seems better.

The focus shift only occurs between f/4-f/8 and only in limited circumstances. So far, in my use, i get none at all.
