Apart from a small smudge on the barrel (seen in the pictures), I cannot find any issues with it. The glass is clear, the DB mechanism works properly. Very sharp lens, covers 4x5 with plenty of movements. My guess is that it will also cover 5x7. It is on Sinar DB lens board. I have been using it on my Sinar for over 15 years with great effect. Now downsizing, selling it along with other LF lenses in other listings.
