Hahahah tragic but painfully true. To make matters worse, it was attached to my much loved Leica M6 TTL 0.58x at the time...
Whiskey was involved, unsurprisingly. Was late at night, I was getting out of a cab jammed full of people, and apparently didn't notice my M6 slip off my shoulder (was slung over a Domke bag). I sure noticed it the next day! But then it was too late..
The M6 TTL 0.58x I recently replaced with a M7 0.58x, so I'm not hurting too bad there - it's everything I liked about the M6, plus some new tricks like AE.
The 35mm Summicron ASPH on the other hand I still haven't really replaced, which I do miss quite a bit although it was just a secondary lens. I got a 28mm f2 ultron thinking it would fill that job, but I really do prefer 35mm to 28mm. Some time early next year I think a ZM 35mm Biogon may hopefully fill it's shoes..
