Reverse Mount Adapter for Sony E-Mount (40.5mm, 49mm, 52mm, 55mm)

Locking reverse mount adapter for Sony E-mount cameras and lenses with 49mm filter thread. Allows for closer focus photography without a macro lens. A manual aperture lens is recommended.

There is a printed thread on the model, might take a few tries to correctly align the first time due to 3d-printing imperfections. Holds the lens securely.

Tested on (and developed for) the Meike/Neewer 35mm f1.7 on a Sony A6400. Magnification is about 1:1.5. The focus depth is really shallow, a higher f-number helps increase it. Also causes distortion vignetting, so an extension tube is recommended.

I only have a 49mm threaded manual lens, so I only made this model. If anyone wants a different diameter thread, just ask :D

Update: Added 52mm model, untested

Update 2: Added 55mm model, untested

Update 3: Added 40.5mm model, tested with 16-50 PZ kit lens. To control aperture it must be set electronically and the lens removed before turning the camera off.
