Hi Everyone, here is a shoe-mount Canon viewfinder for 50mm lenses (on 24x36mm format). It is clean and looks like it had little use. This one has a button on the bottom that adjusts for parallax. Certain Canon rangefinder bodies did this automatically. There may be the slightest amount of haze, but you do not see it when viewing. It comes in a cute little conical-shaped plastic case. How does $99.98 sound? I will cover postage to a USA address. From a climate-controlled non-smoke home. Thanks!
