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.

    A superb photography lens may cheap cost about 1/10 of what a good cinema lens or servo zoom ENG style lens. A decent low-light performer with the right footprint. But then I realized, while I was happy to regain the ability to shoot macro shots.

How To Install OpenMemories AppStore

Image
OpenMemories App Shown on Camera's Application Tab DHI Enterprises shows us how to install a third party application for Sony Cameras which support the PlayMemories Camera Apps. The third party OpenMemories AppStore can now be installed using the same method shown. WARNING from the OpenMemories AppStore developer: Is it safe? This is an experiment in a very early stage. All information has been found through reverse engineering. Even though everything worked fine for our developers, it could cause harm to your hardware. If you break your camera, you get to keep both pieces. We won't take any responsibility. However, this seems to be safer than tampering with your camera firmware directly. We're just interacting with the isolated Android subsystem. Apps you install this way can be uninstalled in the applications manager. In the worst case, a factory reset of the camera clears all data on the Android partitions. How To Install OpenMemories AppStore on your Sony C...
