My Wollensak Vitax is huge. I can't imagine the average field camera would handle it. Not because of the weight [it's mostly air] but it needs a big lensboard. I think a Sinar size board would be too small.

I'm wondering when did these lenses go out of fashion? Mine was caked in enough dust to grow a full farm. Studio shutter was no better. It all came apart for cleaning but it wasn't a pretty sight in the beginning.

I'm guessing many of these lenses have been sitting unused in cases for a long long time.
