i have a olympus zuiko 24mm F2 lens with an Leitax adaptor for EF mount. I am using it with the BMCC video camera. I am experiencing a problem where the lens cannot focus past 100 yards. Even if the lens focus ring is set to infinity the focus point is not. The adaptor seems to have some play in it, perhaps this is the issue? I have contacted Leitex and we are in the process of troubleshooting but also thought I would post here to see if anyone has any thoughts regarding how to solve this problem. Thanks in advance.
