i have one!
it came with my 4x5 camera, i only tried with some e6 film, colors and contrast are quite pale against other modern lenses, to me it has the look of an older lens not a 10 years old one, i'm not an expert and i have just tried another 90mm lens, so take my advice as a pinch of salt.
in hand it looks cheap and small but if you travel with it that should be good thing, and it takes 40.5mm filters.

pd. it let me enough movements without vignetting, i haven't tried any extreme movements, but for normal stuff there´s plenty of room
