Adjust Infinity Focus on NEX Lens Adapters

sony NEX lens Adapter Adjust Infinity


Here is a generic Leica M to Sony NEX E-mount lens adapter. The adapter allows for infinity focus but it occurs before the infinity mark. We wanted to get closer to the infinity mark so we took off the (4) screws that attach the silver part to the black part. We used a precision slotted screwdriver and made sure not to strip the very tiny screws.




We used pieces of aluminum foil to add thickness to the adapter. This will get the Leica M lens farther away from the Sony NEX sensor and infinity focus should be closer to the infinity mark on the lens. If the foil is too thick, the lens will be too far away and infinity focus may not be achieved.

Reassemble the adapter and test the lens for infinity focus.

    any way to do the opposite?
    I have an adapter to Nikon F mount and a very old Rokinon manual tele-lens, which doesn't always quite able to focus to infinity

    @ Örs - you must obviously remove rather than add to your adapter depth in this case, by carefully filing/shaving some of it off - not so easy though!

How To Install OpenMemories AppStore

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...
