Is there and difference in focal length of a EF lens when used on an R body Mirrorless, while using the EF to R adapter? I'm still in the SLR world and calculating the change over to Mirrorless.
Thanks in advance.

So it depends on which R-series camera you use the lens on. Just like with DSLR cameras from Canon, there are full frame and APS-C sized sensors in the R-series as well. The same logic applies as with the DSLR versions. great info thanks so much My Stuff 1D MK IV, 5D MK IV,1D MK II, 100-400L, 28-70 2.8L, 580EX II, 70-200 2.8L IS,16-35 f4L. www.humphreyimages.net
