I recently purchased this lens as a leap of faith. I eventually want to set up an 8x20 system and was hoping this lens would cover the format, maybe even with a few movements. As I said it was a leap of faith in that I purchased the lens without knowing exactly what its capabilities are, but it was so inexpensive and already mounted in a board that I went for it. The aperture is smooth all the way down to f/128, the optics seem in good order (is this a multi coated or single coated lens?) except for a little dust between the elements.
I understand that the true way to see what I’ve got is to shoot with it but I am going overseas for a year and won’t have time to play with this lens on any format before I go. Any practical experience would be appreciated.
