This is a garden variety Leica IIIg with an M-mount shoe-horned onto it by a guy in Wisconsin. The seller is selling it on Ebay and wants $5600 for it (http://www.ebay.com/itm/Rare-Leica-I…3D222038038261). According to his description this is a must have for a collector:
Norman Goldberg (inventor of the Camcraft N5 Motor and the Leitz New York Motor), went to Wetzlar in the late 1950’s and he was shown the Prototype Leica IIIG M Mount. He was inspired to try to convert one, and he did, he converted 5 or 6 IIIG Screw mount Leicas to M mount. This camera is still in the possession of Norman Goldberg’s son, Don Goldberg. Don has checked the camera and it is 100% functional. It is a Very Rare and Unique Camera which should be part of any serious Leica Collection, or if you prefer shooting with finest Screwmount camera Leica ever made with your modern M Mount Aspherical Glass, this is the camera for you! Don has checked All functionality and has gone over the camera with a total CLA, and the camera comes with a 1 year warranty from DAG. Do Not Pass Up this opportunity to add this to your collection! Good Luck!
Now, granted, Don Goldberg is a great guy and all, and I’m sure his father has an impressive lineage with Leica cameras, but why would you pay $5600 for this so you could use “your modern M Mount Aspherical Glass” with it, when you can buy a decent IIIg for $500 and a Screwmount to M Adaptor for $25 and get the exact same thing? [*Of course, as pointed out to me almost immediately by alert leicaphile David Smith, what you would need is an M to screwmount adaptor, which doesn’t exist, for my scenario to play out. This is what happens when you blog after drinking too much bourbon. So….damn if this camera isn’t a unique IIIg afterall. But $5600? I’m not sure I see it when you can buy any number of modern SM voigtlander lenses if you’re looking to use modern optics on a IIIg. Of course, this begs the question of the value of the camera as an historic item].
In any event, somebody will buy it and be very happy they did, for whatever reason. It just won’t be me.
