Helical Mount Leica M to E-mount Lens Adapter Retracted

Hawk's Factory has produced a Leica M lens adapter for the NEX E-mount that incorporates a helicoid. The helical mount, when retracted, places the Leica M lens at the correct flange focal distance from the NEX's APS-C sensor to achieve infinity focus. At minimum focus distance (MFD), the lens can be moved further away from the sensor by using the helicoid, acting like a macro extension tube. This will allow for focusing closer than the lens' native MFD.

The Helicoid Leica M to NEX E-mount Lens Adapter was tested on several lenses and here are the outcomes:

• SUMMILUX 50/1.4 V1: MFD 1 meter, with adapter 0.43 m
• SUMMICRON 50/2 V5: MFD 0.75 m, with helicoid adapter 0.38 m
• HEKTOR 73/1.9: MFD 1.2 m, with helicoid adapter 0.73 m
• SUMMICRON 90/2 V3: MFD 1 m, with helicoid adapter 0.73 m

Rangefinder shooters know that MFD is one of the drawbacks of using rangefinder lenses and Hawk's Factory has come up with a nice solution. Hawk's Factory can be found on eBay.
