Last night I prepared my cameras and lenses for a trip and discovered that I have two (!) Leica lens hoods for the 2/50 Summicron M, but none for my 2/35 Summicron (2nd version). Wow. How did I do that? (You will find the second hood in the classifieds soon...)
I also found that it would not be a bad idea to add hoods for my Canon 2/100 and 3.5/135 LTM lenses. The big one has a 58mm thread, the 135 has 48mm. I also have a 2/35 Canon with a strange 40mm (not 40.5) thread and a Zeiss Sonnar 1.5/5cm wartime LTM lens with (I think 40.5)
Did I mention my Zeiss Contarex Biogon 4.5/21 with the Leica M adapter? Well, that is one of the lenses in the world that probably does not need a hood, but...
Are there any 3rd party lens hoods available for this little collection that you can recommend?
