Contax Makro-Planar T* 60mm f.28 C Macro

As good, optically, as the AE. The AE has a slightly better feel to it as the barrel is designed for focusing down to 1:1 and mechanical quality is un-sur-passed.
The 60 "C" focuses down to 1:2.
Takes 55 mm filters, handy size.
Near perfect lens.

Tack sharp
Lightweight
