Yes I’ve used this lens a good bit on the R5 and R7 and overall I like it. It’s great bear and with the 1.4x iii but I am not so happy with performance with the EF 2x iii unless the lens is stopped down a stop at which point you basically have a really expensive and heavier RF 800mm f/11…

Yes - the EF 2x iii is a bit much. The combination also has somewhat weird bokeh and I'm not quite sure if it is the DO, the TC or a combination. RF 2x is somewhat better, but I tend to use it mostly with EF 1.4x iii.

Do note that the IS on the lens is not as effective as current ones. Otherwise I like it on R7.
