I just received it on saturday. The Extreme is awsome , after i hook it up with my fx1 and nikon 50mm . The lighting much better , it build very solid. No more vignette ( my biggest issue with the old 35a ) . and i Think the letus extreme is the best 35mm adapter on the market.

THanks Hien & Quyen so much.

I got mine today!! - unpacked everything and......

I got the wrong mount -it's a Pentax K and all my lenses are canon FD...... Nooooooooooooo!!!

I'm sure they'll sort it out

***postscript - the correct mount is already on it's way
