I have for sale a beautiful Mamiya C22 TLR with a Sekor 135mm f4.5 lens (seikosha-MX shutter). The camera body has a little staining on the leatherette but is otherwise in very nice condition. There is a kink in the upper part of the bellows but they're light-tight. I just replaced the film door seals with new foam and cleaned it up. The lens would probably be considered a "bargain" grade, but it doesn't have any issues which would affect image quality. The lens shutter speeds are a tiny bit off but not enough to be a serious problem. Missing the lens cap. I also have a left hand grip for this camera (forgot to take a photo of it) but it's missing the cable release part. It can probably be replaced. Starting price $200 but I'm flexible.
Siguii, have you used this camera? I am wondering how accurate the focus is. With age the pad under the ground glass can shrink just enough to throw the focus off.
Yes, I shot one roll of film through it. A couple shots were out of focus, but I had attributed it to my own error. But since you brought it up I may try shooting a test roll to confirm that, provided there's serious interest.
If you want to be sure, try shooting at a wall at 45 degrees. Decide on your focus point. You will need to understand the Pythagorian Theorem and the mathematics of Lenses. The repair manual has a very specific procedure for doing this.
Other than that, just sell the thing as is. I'm looking for a second body so I can have color and B&W loaded at the same time.
