Hi James, nope. You just screw it on. The 10mm needs to be of the newer, non-waited type. But if it is a preset you're all set. If they are indeed in good condition that is an excellent price! Enjoy your lens! The 10mm is my favorite lens on my Bolex, I don't dig the 5.5 that much though as the vignetting is a little too much for me.

Nope, no way except for zooming into the footage a little in post. As for why I guess it's due to the design of the aspheron. It's a .55 wide angle adapter after all,which is quite bit of a change! And some wide-angles will have light fall-off into the corners no matter what. Many WAs for large format photography have that, the Super Angulons for example. You sue a center filter to cure that in photography though. And you'd loose around 1.5 stops with those. Cheers, Dave Link to comment Share on other sites More sharing options...

Premium Member Phil Savoie Posted September 18, 2009 Premium Member Share Posted September 18, 2009 You are made a good buy the price was fair and the kern 5.5 aspheron was better optically than the 6mm later produced for the 10mm by Century.
