The Good Value Wide Angle Performer
Contax 28/2.8 Distagon T* 2.8/28 28 f2.8
Contax 28/2.8 Distagon T* with Contax 55/67 ring as hood.
A nice compact wide angle lens with moderate speed and very good performance. The lens can be purchased at very reasonable price. I am very satisfied with its image quality and to me it is as good as the ZM 28/2.8 Biogon T* for most practical purposes.
