I just had a thought about my preferred lens lengths and had to share. Of the film cameras out there, I've been drawn to the Leica CL (aka the Minolta CLE, the only Leica-branded M camera made in Japan). Aside from its small size, I hadn't really identified why it resonated with me. I figured it out! The camera came with a 40mm lens and a 90mm was optional and is the only M camera to have 40mm framelines. Obviously, most other Leica lenses would fit (a few would not, but that's another story). My GF1, well, I have two lenses for it. 20mm (aka 40 effective) and 45mm (aka 90 effective). It hadn't really hit me how much the GF1 really was the digital version of the CL.
