I like the LA-FZB adapter in that it communicates with the B4 lenses. I "think" both the HDx35 & LA-FZB correct B4 optics designed for the CCD Prism (please correct me if I'm wrong)
I do like the HDx35 adapters universal mount system to keep it compatible for future cameras but it doesn't communicate with the camera. I know there are additional expensive mounts should I want to go from PL to Sony FZ that will communicate with lens and I can put on the HDx35, but seems like a waste.
Specifically, I wanted to know about compatibility with the LA-FZB. I currently own C300s. Can you go from FZ to EF (as in put the LA-FZB on a C300? I know you can adapt EF to FZ but I want FZ to EF
Is there a chart showing mount compatibilities? Can't find one online.
