RF 600/800mm f/11
#30
Yes, Dave, I would have to try before I buy!


As an aside, I believe that the 20MP (full frame) camera is not diffraction limited until about f/13, so for that camera, if I am right, it would not be absurd to expect sharpness. And I was serious that the aperture stopping down can effect sharpness.

Now about my fantasy...I have used the 70D, and you have been using the D500, both of which are APS-C, though I had to deal with a tougher 1.6x versus your 1.5x. I used my 70D for Macro quite a bit at f/11 and didn't seem any the worse for it. I know in theory there should be diffraction, but since it was often necessary for a sufficient DOF I had to use it. Therefore I am not expecting it to be unusable with a telephoto.

Still, I would, in reality, want to go back to 20mp. I can always do some shooting at f/11 with the 90D, but now that I think of it...I have been mostly shooting wide open. If you can call F/5.6 wide, that is!

The truth that is sinking in, is that I am hooked. I think I might actually want an RF camera! Maybe not now. But soon!
