I so wanted a 21mm lens for my Leica MP (Typ 240). But I had doubts as well. The primary issue is of course that Leica does not have 21mm framelines, which means that one has to compose using live view and focus using the range finder. Clumsy but one gets the hang of it. But I did not want to spend too much money given its not a daily use lens. In the end, I decided on the Voigtlander 21 f4 Color Skopar. Not as expensive as the Leica or the Zeiss offerings, But at the same time, very sharp and has good character. Also, the f4 aperture means that its really small and light – I have literally carried it in the pocket of my cargo pants and its been perfectly fine.
The photo below was taken on my second day with this lens. I love the reflection of the evening’s city lights on the car. This composition was pointed out to me by my daughter – I was originally taking this from too far out. The photo was given some additional oomph through the use of the Kodachrome 64 preset by Gary Tyson of F8 Photography in Hong Kong.
