Has anyone actually experienced focus shift with the RF 100 macro ?
I’ve read a review the past that the reviewer had focus issues which was attributed to focus shift t
Also read online that Canon's engineers have acknowledged that the RF 100/2.8 exhibits focus shift as a necessary design compromise for achieving 1.4x magnification
I have never felt like 'Focus Shift' has been a problem with the RF Macro. It may do it, but I don't shoot in a way to makes it a problem. That said, I don't do focus stacks, which is where I would assume is the biggest problem for a lens that shifts.

I shot a bunch with the EF version this weekend. At a distance, it was able to focus track on my running gsd's eye really well. Amazing how many in focus images there were. Up close, the focus struggles more on the R5MKII than on my 1DxIII. I have ordered the RF version so I can compare them both side by side and will keep the one that I feel does a better job for my needs. I will say the files from the R5MKII are pretty damn amazing and the AF is incredible. I also shot with a Sigma 60-600mm with ef 2x converter hand held and the af worked really well. Something I could never do with the 1DxMKIII or any other previous Canon model. ...Show more →
I think you'll find that the RF version is a step up. I did. I really liked the EF non L version, but feel like it shows its age in use. I'm not sure if there was a little bit of uncorrected CA, but the RF version just seems better. Overall, the images just have an improved richness. One difference, I found that I never noticed the exposure drop off on the EF lens at close focusing, but it is super pronounced on the RF lens. Again, not sure if that was simply me being oblivious, or if the EF just managed it better and fell off less (which is likely the case being x1 vs x1.4 magnification). Like it was said before, the bokeh on the RF seemed a tick better. Everything seemed to fall off a little bit smoother. I feel like both AF'ed fairly well at really close distances, however that might be bias from memory. Personally, I'm team RF for the lenses in question, however I've never touched the EF L Macro, so that may be on another level.
As far as contrasting the differences in the newer cameras and the 1DX III, you won't miss anything but the battery life and the extreme de-focus performance. Even the R50 is going to run circles around the 1DX III in terms of AF. I find that the AF with TCs on big f/4's, are almost as good as the lens bare. Not a lot of AF performance drop off (if any), unlike the DSLRs.
