Hi,
Is there a relationship between the ground glass and the lens ? eg. If you had the sharpest lens out there would that mean you'd need an exceptionally finely ground glass on the camera to focus the lens perfectly ?
I've got a lens that doesn't seem to easy to focus. I'm trying to determine whether it is a lens issue or whether I should get out the carborundum paste or something. I do have a Chinese camera so I do appreciate there is room to move in grinding the screen some more.
I also would appreciate an opinion on image 'glow'. Some lenses seem to glow more than others. No not the soft focus Kodak Portrait ... I'm talking modern Schneiders and Rodenstocks. The Sironar S 180 seems exceptionally sharp and clear. The 110 SS XL seems to glow on the ground glass to an extent. This glow makes focussing harder too.
The lenses themselves look to be in exceptional condition. There are no marks nor damage that I can see. So I wonder if the ground glass could be the issue. Perhaps it is the loupe ?? A Silvestri in this case. How is a lens of this vintage affected by minute differences in where it is sitting in relation to the shutter ? Could it be that they aren't seating correctly ? Maybe a dimensional issue ?
The thoughts and experiences of the LF community is needed !! Please dont mention the operator. I realise there are limitations in operators !
Cheers,
Steve
