I used a packard shutter a couple inches inside the camera. It caused some vignetting on several of the lenses I tested out.

I took some images with the lens for those who are interested. Here are 3 pictures with the diaphragm set at f3.5, at f6.3, and at f18. I took the pictures on 8x10 photographic paper (Aristo MC RC)...

The f stop goes 3.5, 4.5, 6.3, 9, 12.5, 18. The lens probably was made post 1900. The scale looks similar to some Stigmatic lenses I see which were in the post 1900 years. I can take some test...

Does anyone know the brand of this shutter? I've never seen one like it before. I thought it might be a Multispeed shutter but it does not appear to be based on searching google. There are no...

Thanks for the replies. I compared this lens to a 7 1/4" and a 9" Veritos that I have and they are different in size and curvature. The element in the Wollensak shutter has more curvature in the...

It's hard to tell from the photos but the front slopes in to the shutter blades. There would be no area to put any of the Imagon disks. Here are some links to sharper photos.

I recently got this soft focus lens but there is no writing on it and am trying to identify it. The lens came on a Wollensak shutter which looks original as there is no place for a front element to...

It is from a string set Kodak box camera. Looks like you have the original brass string pull knob which are usually lost.

Thank you for your comments. I'm still studying the lens. Here is another picture showing a better angle of the gear track. I'm pretty sure it is a normal radial drive. One feature I didn't...

I have a large early petzval radial drive lens which is missing the outer housing that would have said who the maker the lens was. From looking at its construction is anyone able to indentify the...

I have an unusual brass lens that I have been trying to identify. It comes in a brass recessed unit to fit the lens deep into the camera. The rear of the lens is almost identical to a Harrison...

It is interesting in that the camera looks to be of American manufacture. Probably an Anthony studio camera which were made from the 1880's to the early 1900's.

Hi, I have a camera that looks exactly like a Russian FKD view camera. It takes 9x12cm sheet film holders but when doing research on it all I can find are Russian 13x18cm and larger versions of this...

I can see why someone might think this is American because of the box joints on the front case but with the very wide metal gear tracks with the grooves at angles seem to be a very European feature. ...
