I picked up this lens a few months ago as a curiosity. I believe it came off a Rochester Camera Co. 4x5 plate camera, made sometime between 1893 and 1902.
It is in a Unicum pneumatic shutter, which still seems accurate. I have taken pictures using this shutter on the DSLR (with the DSLR shutter set on a long exposure) and the 1/100 and 1/25 speeds seem to be spot on vs the DSLR shutter. Thats a testimony to 1890's materials and engineering !
Sadly, though the shutter is good, the lens is pretty awful. I am easy to please with respect to lenses, but this one is just not sharp in any conventional meaning of the word. Now, back in 1900, on the 4x5 contact prints this was designed for, perhaps this was not apparent, but on a DSLR it is noticable even on web-sized images. I am disappointed, as the appearance of the lens on the bellows is very striking. I would say that this lens is just barely usable on the DSLR.
Samples - pretty much every aperture from f/8 to f/45-ish. This thing goes to f/128 ! Maybe its sharp at f/64 ?

You say it isn't sharp... ok, I should not judge from resizes, but I think it can be said that it musn't be all that bad, after all. A really blurry lens makes images that look blurred even when resized. _________________ Orio, Administrator

That is a GORGEOUS lens, I'm in love...
The photos look good to me - these aren't modern lenses scaled for the miniature size negative, after all, so it's no surprise they can't match a modern lens for sharpness. LOL had they even invented electronics by then? much less a digital camera. I wonder if anyone thought their lens would still be in use now, and in what way... _________________ -Jussi

I'm using their ultra compact soft torik lenses on my eyes and I'm very happy with them
I didn't know that they were producing camera lenses and yes the images are great if we consider the age of the lens. _________________ My name is "Yalcin", and exactly "Yalçın" and here you can find my MF samples:

That thing looks like the lovechild of Star Wars meets Jules Verne... The photo's however seem sharp to me? Is it my eyes or am I just happy I can see at all these days?
Wonderful contraption - now I'll have to see what I can cram onto the front of my K10D (or Lumix L-1)
