yesterday I received my Bronica ETR Si with two lenses. While shooting the first roll of film, I noticed that the focusing screen showed objects ~200 meters (~650ft) in focus even though I had set the lens to infinity. At first I thought it was a problem of the lens, but when I changed from the 75mm to the 50mm the problem persisted.
So I locked the shutter open and placed the ground glass where the film would be. Thankfully, the image looked focused there (so definitely not the lenses). When I put it back in, I noticed that the screen wiggled around a little. It seemed to be suspended from the two metal clips on the edges (one of those is loose). My guess is that these clips are holding the screen above the plane where it should be.
My alternative diagnosis would be that the mirror is misaligned, but because of the wiggling I'd say the fault really seems to be with the ground glass.
Is this fixable? How would I do this?
Thank you for your help.
