Hi all, So i just purchased the Mamiya Ruby Standard f/2 48mm rangefinder, and importantly this is my first ever rangefinder camera or rather first ever manual analog camera (all the while I've been using point'n'shoots). And as a typical newbie not having the slightest idea, and due to the severely lacking information regarding lens hood for analog cameras online, I went and bought me a screw-in 48mm lens hood (vented metal) from a guy who had used it for his Canonet QL17iii. The newbie in me thought that since my Mamiya spots a 48mm lens, and both it and the Canonet are fixed-lens rangefinders the 48mm lens hood would be fitting. But the thing is, if it had been fitting I wouldn't have created this thread! Can someone please advise me on what size of lens hood I should get for the Mamiya Ruby Standard?
