Is an adapter available that will fit into a "bay one" size thread on a Yashica A TLR?... The filter's made for this thing are VERY expensive/ I have found very few. I guess a 55mm/ 58mm will be best so I can use some of my filters I allready have. Does anyone know where I can pick this up?
Bay 1 to 46mm or 49mm should be easy enough to find. Putting a 58mm with a hood on a Yashica with its 45mm lens separation may block your viewing lens a little.
There is a recent thread further down (by me) asking a similar question, but Bay 1 to 52mm for using Nikon filters. One of the answers was to call Jimmy Koh 516.826.9566, which I did and bought one for $15, plus shipping. Works great on my old Rollei. And I don't see the top edge of it in the viewing lens either.
Re the lens hood - I don't use one. Since everything I shoot with that camera is on tripod, I use my hand or something to shield the lens, never bought a hood.
Another recommendation for kohs here (see kohscamera.com). I got one for my Yashica MAT 124g in 49mm because I already had a standard hood and a number of filters in that size. Works great for me and I find it doesn't get in the way of the viewfinder even with the hood on -- it might darken the bottom of the view just a touch but doesn't block any part of it.
