Which Lens Adapters and Lenses are you using on the Nex Camera System??

Rainbow Imaging E to K-mount adapter. I use it with the Konica Hexanon AR 50 1.7 shown here.

I also have a Tokina 100-300 f8 zoom which is really tough to use because the focus is very, very touchy. It's nice to have the length sometimes, but it's not much fun to actually use.
