Wollensak 3" F:1.9 fast aperture Oscillo Raptar

I am looking for an wide angle lens (equivalent to 20mm in 35mm format) in
4x5. I see this lens show up in ebay now and then and am wondering if it is
worth considering.

Thanks
Shawn

it [a Wollensak 3" f1.9 Oscillo-Raptar] is worth considering.

It covers 3x4" (Polaroid pack film) at roughly 1:1.

The best you can get out of it is (maybe) a not-very-good normal lens for
6x6cm. OTOH: it _is_ an f1.9 which is very fast for MLF -- maybe a 6x7
back on a Graphic would be a good application.

As has been said befo There are _NO_ cheap wide angle lenses for
large format photography.

The cheapest one can do is a 90mm f6.8 Angulon for around $200.

A 75mm LF lens in ~f4.5 will set you back $500+.

psst.. want to buy an f-stop timer? nolindan.com/da/fstop/

As the name suggests it is for photographing oscilliscope traces, which
means it is for working at very close distances.
At infinity its probably lousy.
