Improved Argus C3 Lens To Leica M Body Adapter

thingiverse

The [Argus C3](https://sites.google.com/site/fromthefocalplanetoinfinity/argusc3) 135-film rangefinder camera, made in Ann Arbor, Michigan from 1939-1966, is a bit of American history. About 2 million of "The Brick" were made, and many survive. The interesting thing is that the clunky camera used screw-thread-mount lenses that are simply adorable: tiny and exquisitely well made. Some lenses were made by Bausch & Lomb, others by Enna Werk in Germany, and a few came from Japan. Unfortunately, that doesn't make them great optics -- but they're OK, and did I mention that they're adorable? Commercial adapters to modern mirrorless cameras are available, but a bit pricey. There is a little problem with inconsistent flange-to-film distances, so many adapters allow some adjustment. Ok, so why 3D print this one? Well, first, it's really easy to print. Beyond that, I haven't seen any other C3-lens-to-Leica-M-body adapters. With such an adapter, these adorable little lenses can be used with the [Techart Pro LM-EA7 adapter](http://techartpro.com/product/techart-pro-leica-m-sony-e-autofocus-adapter/)... which makes them able to focus somewhat closer and autofocus. Well, the LM-EA7 can only autofocus if you're within 4.5mm of focus movement from the correct focus, but that works very nicely using the LM-EA7 to tune manual focus: you use manual focus to shift the autofocus range. Note: This is an improved version of [Thing 3095199](https://www.thingiverse.com/thing:3095199) which has been re-toleranced to be a better fit, and now has two multicolor versions.
