So yesterday was the annual "World Photography Day" (August 19th, the date commemorating the Daguerreian process). If you missed it, well, I almost missed it too.

So yeah, I picked up another film camera that I don't need. I figured it would be nice to have a film camera compatible with the manual focus lenses (Leica M mount compatible) that I've been acquiring lately. All the better if it's a rangefinder camera too.
