Black or chrome is not important for the quality of the pictures. But it´s important for the look and feel of camera and lens. As Magus I like the little extra weight of the 35 and 50 ´crons in silver - they feel better. And I like chrome on chrome - if something looks nice, it´s nicer to handle than something "ugly". This is meant in my own personal categories of aesthetics: I don´t like a black lens on a silver camera.
So after this statement: Martin, your MP with silver lenses look great. And I don´t mind pictures showing the workspace. They have an almost advertorial look, make me want to go home and pick up my camera.
