I need a viewfinder for my Leicaflex body when I have my 21mm lens on it. Is this what I need?
I purchased this accessory for the Voightlander angle finder because I have a variety of lenses for the camera I use it with. That finder has interchangeable lenses, mostly very wide. The finder itself is square format but has bright lines for 6/45 format as well. Not good for 35mm, unless you are willing to work with a cropped image. Worked beautifully on my Alpa TC with 6x6 back. It works at right angle to the ground or vertically as well.
hope that helps.
