I've got a quantaray 80-220 zoom in fd mount that I like to use occasionally with my e-pl1. Generally I have to use it handheld and braced on some kind of solid support unless it's very bright out allowing for very fast shutter. I'd like to be able to put it on a tripod, but it's too long and heavy to mount it using the 1/4-20 lug on the camera. I'd be very worried about breaking the mounting lug or worse, the lens mounting flange. I've tried to locate a ring mint that would work with this lens so I can mount the rig by the lens instead of by the camera body, but I'm having no luck. Has any one done this diy-style or can you recommend another means of mounting it? Thanks!
