OK and tiny lens.
I bought mine new in 1993 and it was then stolen.
I was never that impressed with it on my 4 x 5. I always felt it had a bit of light falloff in the corners, which is what you should expect from a lens this wide on 4 x 5.
The coverage was iffy for extreme movements on 4 x 5, but that's again what to expect from a lens this short of this design and this small. I prefer German lenses since that's my personal heritage.
52 mm filter thread.
Six elements, four groups.
200 mm image circle.
7 oz or 200g.
Copal #0 shutter: T, B, 1 - 1/500.
Stops down with seven blades to f/64.
Linear scale, no click stops, marked at third stops.
I'd go for a Schneider instead, even an ancient old Symmar convertible like my 150mm here.
