There is a lot of talk about focus shift of the RF 100L macro. I have used the lens without any issues and have been wondering a long time what's that talk is about.
So I have made four series of pictures with changing aperture.
Subject is a dead hummingbird moth I found and which is pefect for a "real life" test.
I put the camera on a tripod with a macro rail to focus, connected it to my PC. Focus set to manual, IS off.
Electronic shutter and 10s delay to prevent shake. After focussing I didn't touch the camera and set everything via PC.
The focus is set on the eye like in real life by using the 15x preview.
For every magnification I first post the uncropped picture at f/2.8 and f/32.
First 1:1.4 or better mfd
And 1:1 crops 2758x1551
f/2.8
f/4
f/5.6
f/8
f/11
f/16
f/22
f/32
The DLA of the R5 is f/7.1 so @ f/8 und higher thegeneral sharpness decreases but still the eye is the most sharp subject. I see no focus shift issue.
