Excellent. Terrific resolution from that lens and great lighting with very good control of refection. Is this a finite lens? Most Zeiss Jena objectives I see on Ebay are infinity corrected.

Excellent portrait. It seems that this objective doesn't need CA correction at the eyepiece like most Zeiss. Could you give us more info about the objective and camera used?
