(At first I thought I'd broken the thing!) Here's the catch, though: the thread on the lens head is NOT 39mm. it is somewhat smaller (37mm?). Would this thread be designed to mate with a close up device or are we busy merrily hacking up our lenses? :-< The Hove Leica guide (4th edition) makes a point of mentioning which lenses have the detachable lens sets but they don't say anything to this effect about any of the Summicron 50s. <GULP!> Jae
