An anonymous source sent me this first image of the pre-fina IRIX E-mount adapter version (Thanks!). He told me this:
First image of the Irix original adapter for Sony. Infinity focus works, chip for focus confirmation too. And is wheater sealed.
Prices will be below $100.
Press release will be available in around a month.
The adapter is made to support Canon/Nikon IRIX lenses on E-mount cameras. I guess that you can use also original Canon/Nikon lenses on it.
IRIX lenses are currently on sale at Amazon US, Amazon DE, Amazon UK.
