I like to shoot with wide angles when using a rangefinder camera. I don't know why, they just seem set up for short lenses. The focus works great and the viewfinder is easier to view through.When I travel I usually take along my longer lens, the Zeiss 85mm f4, but most days I leave it in the bag.
At the local Blues and Western Concert I had a chance to walk right up to the stage and shoot a few with the 85mm on my M9.
I found that I really had to concentrate to get the pictures in focus and the correct exposure. Harder than I usually work when using a dSLR.
I think the effort worked out and these three images worked well.
