John Emery Posted July 31, 2016 Share Posted July 31, 2016 Hi! I just bought 2 C/Y lenses for my BMMCC, and after trying them out, they don't seem compatible with the Speedbooster (Pocket). They do connect properly, but the aperture blades stay totally open and they don't close. Has anyone had this same problem? Any workarounds?

mat33 Posted July 31, 2016 Share Posted July 31, 2016 The AE lever on the C/Y lens doesn't fit properly with the EF mount BMPCC speed booster. They need to be filed down to fit, check out this thread on BMCuser about it: http://www.bmcuser.com/showthread.php?17173-Contax-with-Leitax-Canon-EF-Pocket-Speedbooster-BMPCC John Emery 1 Quote Link to comment Share on other sites More sharing options...
