60/2 Apo-Lanthar E testing started

I received my Apo-Lanthar today and tested it off-axis to make sure it was a good copy.


It is.

Tomorrow I'll start with LoCA, on-axis sharpness, and focus shift tests, probably at 1:10. From the screening test, I expect this to be a very sharp lens on-axis.

Notes: lens is metal and solid. Focus throw is about 300 degrees, which is about as good as you can do without a really expensive helicoid like Leica uses sometimes. That makes distance focus wide open a little twitchy.

If there are tests anyone would like me to run, please let me know.
