Zeiss ZM 28mm f/2.8 Biogon T*

The Zeiss ZM 28mm f/2.8 C-Biogon (about $1005) is a relatively inexpensive 28mm lens of very compact dimensions and light weight.

Composing with the 28/2.8 Biogon can use the optional 25/28mm ZI viewfinder, or the built in frame lines of the Leica M9. The rectangular lens hood is also advised.
