This review is from: M42 pentax, Carl Zeiss, Praktica, Mamiya Lens to Canon Eos 1D 1Ds 5D 6D 7D,70D 50D,60D,1200D 1100D 100D 600D 550D 650D 700D adapter Ring. (Electronics)
Having read the reviews, i ordered this adapter ring without to much thought, It took 12 days to travel to ireland by royal mail...looked ok at first, but when i tried it out,, oh, oh, it would only thread on one turn to the lens and then lock up, on close up inspection its threads appear to be squared off and the innermost thread still has machine burrs on it. maybe i was just unlucky, but i am dissappointed that i bought a piece of scrap alluminium.
