I’ve recently been testing some very old brass camera lenses that I’ve had for a while and by old I mean over one hundred years old. Some have the manufacturer engraved on them, some don’t. Some of them have aperture blades inside, some don’t and none of them have built in shutters which is why I was testing them on a Sinar monorail camera (below) with a Sinar behind the lens shutter. The downside is the maximum shutter speed is 1/60th which makes it difficult on a sunny day. More testing to come with more detailed results.
[Tech info:] Sinar P 5×4 camera, Watson & Sons No. 3 portrait lens, Ilford Delta 100 film developed in Kodak HC110 1+31.
nice test…nice portrait !
Thanks
What is the focal length of this lens? Can it cover 8×10 inches? I’ve searched all over the internet and can’t find any information about this lens.
Good question. I’m not sure. I will have to dig it out and test it.
