I just received my Tachi 8x10, and I'm playing with it a bit. I have one issue with the "ground glass". It seems to have a "latent" image that stays the same whatever the angle of view, but it also has a "floating" image that changes with the position of your face relative to the glass, and that "floating" image has a slightly different focus AND angle of view than the other. It's also quite a bit brighter.
At first I tought it was some sort of reflection, but even under the darkcloth, and even using a loupe I get this overlap.. It's sort of like a rangefinder double-image, but instead if heloing the focus, it ruins it :D
So I'm wondering if my "fresnel" has a problem, like the frosted side that is no longer frosty enough ? Maybe the previous owner cleaned the glass (that is actualy plastic) with something that cleaned it a bit too much?
Is it a common problem ? can it be fixed ?
