Have been wanting to upgrade to full frame Canon for some time from my 70D, and saw the EOS-R as a way to do this and use my EF and even EFS lenses (at least for now).
However I was surprised that the EOS-R with EF zoom lens at 300mm gives me a wider field of view than my 70D with EFS lens at 250mm. Is this me being real dumb about the effect of moving to a full frame sensor, or is it maybe something to do with the lens to sensor distance being compromised by the EF lens adaptor?
Problem is I like wildlife photography and really need more zoom, not less. I haven't seen any info on high focal length zoom lenses coming for the EOS-R (RF lenses).
Attached photos are 70D/EFS lens at 250mm followed by EOS-R/EF lens at 300mm. I exported them to JPEG and shrunk them by a factor of 10, so the EOS-R image is larger due to the higher pixel count. If I make them the same size then the difference in field if view is even more apparent, and if I had taken them both at 250mm then even more so.
