560 in the lens x 1.6x in the camera. A 20 mp crop is a hair over 2x.Actually, you have less reach, 560mm vs 800mm equiv in the Panny. The extra 12mp of the R7 cannot make up for that if you crop the R7 to 20mp.I shoot wildlife in the ND Badlands. I went from a Pany G9 with 100-400 to Canon R7 with 100-400 + 1.4x TC. I now have a rig that's about the same size, weighs 10% less, costs less, and gives me 60% more pixels and 12% more reach.
I call that a bargain.
All MFT is 2x in camera.
