Yes my EOS 200/2.8 is fine on the A1. Need to experiment on the A7C.
I do need a 300/2.8 and have been looking at used 300mm IS ii's at FM.
Remember Sony patented a 300 and 500 diffractive like the Nikkor PF's. I'd jump
in for those. But with the world spinning probably doubtful.
We're getting close on the whole house remodel so I'll have some play monies soon enough.
I did get Poof a Crosstrek in lieu of me getting a side-by-side but she needed it more. That would
have brought in several things I can't life (600/F4) haha
Yeah the 200/2.8 is such a gem. Glad I kept it all these years.
It's good that I can now use the EF 200 2.8L, but I have the GM135 which is so ridiculously sharp and also very fast focusing, I doubt I'll use the 200 much.
I too would love a Sony version of the 500PF. Maybe someone will finally work out how to make an adapter that works well and we can just get a Nikon 500PF. Or Sigma or Tamron make a DO/PF.
