A while back I managed to get a Docter Optics 300mm Germinar cell set courtesy of Kerry Thalmann. I have been using it for a while as a long lens on my 4x5, and have bee very very pleased with its performance. I recently was lucky enough (though my bank book disagrees) to win a new in box Docter Optics Tessar 180mm mounted in a Copal 3 shutter.
I don't have a lensboard for it yet, but this lens is big. I am wondering what the performance will be like. I have read about the 210mm version and it looks nice.
Any thoughts or comments on this lens would be greatly appreciated.
