Is this a lens?
In the chest in the far corner lies one product of the photographic industry. I'm not entirely sure what this lens is. Looks like an eyepiece from a night vision device or something similar. If you know what this is, please write to me.
This optical device has, in my opinion, a focal length of approximately 75mm and the aperture ratio seems to be 1/1.5. c-mount type. And of course there is no aperture. It can be installed on mirrorless cameras using appropriate adapters. This “lens” covers the micro 4/3 frame and the APS-C frame with a vignette.
Since it does not have a diaphragm, I used an external one, which I put on the front lens.
Here are some shots from this lens on a m4/3 camera.
Paired frames - the first frame with the aperture fully open, the second frame with the aperture slightly closed.
In principle, I think it's very good for such a thing. Under certain conditions, this “lens” could take good portraits.
