270mm and will cover 7x9 at f6.8 and 12x14 at f45
These number are from the Golden Dagor, i believe older Dagors as the Series III could have slightly better coverage.

I have one of these in the same shutter.Of the 20 or so lenses I own,it is by far the most used. It will cover 8x10 at f 22 or smaller. It barely missed the corners on 7x17. The last one I saw sold went for around $350-400.
