when I compare my photos with what I find here and elsewhere on the net, they never look as sharp. Sometimes I do get a sharp one. But I cannot attribute that to a lens of film. It isn't movement, the blur is general, it doesn't have a direction like you normally have with movement.
And if I compare my results with my medium format cameras then I have the same impression. A photo I take with the Mamiya Press or Fuji 690 is sharper and has more definition then a 4x5 using the same film, development and scanner.
So I have 2 cameras. A Wista 45N that I use with 4x5 and a since recently a Wista 45D with a 6x9 back. And each get me the same results, not as sharp as I would expect. Lenses are the same, Fujinon CM-W and SWD, film is Foma 100, 200, FP4 or Adow CMSII. Development is almost always HC110 B (*) and the scanner is an Epson V700. always using a Gaoesi 8x loupe, a tripod and a release cable. Nothing exceptional but more than good enough to give a sharp image. With the Mamiya Press it would be the same film, development, scanner, tripod.... but the result is far better.
So I'm missing something. But I have no idea what. Only thing I can think of is that focusing on the ground glass is the issue. That is the largest difference I see. The distance might be faulty. But how to check? with a rangefinder of reflex, you put a ground glass in place of the film and check. But with a ground glass it doesn't make much difference to change it by another. I did check orientation of the Ground glass, the ground side is towards the lens. Both those cameras do have a fresnel. It is also towards the lens (so between the lens and the ground glass). I have no idea if those are original.
But I'm out of ideas. So what could I check otherwise?
