testing another cheap objective

Post by soldevilla »

Today I received from Surplus Shed some objectives and I have not been able to resist ordering this inexpensive 13mm focal length.

And I'm very surprised at the result! This is a quick and dirty (really dirty... :shock: ) test of a pyromorphite with a FOV of 3 mm. I have to do more testing, but the result is very promising.

That'll be D mount.
Lots of Cine and movie mount specs here:

From the weather exposure guides on the barrel, we can probably guess it wasn't a macro lens. So reversed it would be nearer an infinity type
microscope lens, so try it reversed with a morfanon!
