I believe he reported that focus shifting only happened over f11.

Either way, thanks for the review. Nice shots! I am waiting on one of these myself, but it is replacing a Nikon micro-nikkor 105D which I picked up around 20 years ago and is getting a little long in the tooth.

Thanks!

In his review it looks like he stated that focus-shift mostly occurred between f/2.8 and f/11. After f/11 is seems as though he states it's not an issue, and I wonder if part of that reason is the deeper DoF is "masking" whatever the problem may actually be

From his review;

Basically, focus shift is not a concern at f/2.8 or f/11, and focus shift is not an issue at long focus distances.

Jay,

Is it your opinion that this is pretty much a non-issue for your use of the RF 100L?  I have mine in the book unopened now and I'm just trying to decide if I should keep it or not, as I have the EF version.  Do you still have your EF 100L macro?
