Arri-S lens to Sony E-mount (NEX) adapter

cults3d

An adapter to fit Arri Std lenses to Sony E-mount. The adapter works the same way as the original Arri cameras, ie the lens is held such that, when focusing, the lens barrel rotates and the front of the lens does not. Also the fixings do not crush or damage the lens barrel such as cheap screw clamp mount adapters do. The adapter is in 3 parts, a split-ring that sits in the groove at the back of the lens and between, a ring that the lens rotates in and the E-mount bayonet. The 3 parts are a tight push fit (if printed correctly!), but can also be fixed in position with a few M2 screws. Two versions are included, v3 (the 3 part adapter) and v4 which enables the peg (which stops the lens rotating) to be printed separately, and providing a stronger print in FDM. Length of the adapter is critical to maintain infinity focus, while the adapter is suitable for prime lenses, due to variations in printer accuracy it may not enable zoom lenses to be parfocal. Additionally requires (or not!) 4 off M2 x 20~25mm screws/nuts.
