I picked up a Leica IIIf. (It's my first Leica, and I'm excited.) It's a red dial with self timer, and an Elmar 5cm f3,5 lens.
It hasn't arrived yet from the auction house, due to a snafu with payment (they don't accept Paypal.)
The camera was allegedly "used by" Leopold Godowsky, one of the co-inventors of the eventual Kodachrome process, along with Leopold Mannes. I'm not sure exactly what is meant by the term "used by." I believe Jack Naylor acquired many of the personal notes, and equipment belonging to Godowsky and Mannes (God and Man). I'm not sure this camera was owned by Godowsky, or simply used by him at some point.
Anyway, I'm excited about my purchase, as I said, and can hardly wait for its arrival. Any advice about this equipment? By the way, I intend to use the stuff. I'm a photographer, not a collector, even if I don't photograph as much as I'd like.
