Ngàm TechART PRO SHOTEN CONTAX G - SONY E MOUNT

Shoten claims that this adapter can achieve faster than expected autofocus performance to the degree that it supports face detection and eye-af continuous autofocus. It is compatible with the in-body image stabilization system as well and has a function button that allows it to swap between autofocus and manual focus in addition to a “close-up” manual focus mode. Shoten says that the adapter supports firmware updates via a micro USB connection.

There is also a “focus dial” on the side of the adapter that shortens the original shortest shooting distance of the lens.

Shoten says the GTE is compatible with every modern Sony Alpha E-Mount camera from the a6100 through the a9 II and the a7R IV, and promises it will work with any “high-performance image plane phase difference AF system-equipped E-mount camera.”

The Shoten GTE joins that Techart TA-GA3 adapter as the other notable Contax G to Sony E autofocus adapter. Compared side by side, the Techart adapter is considerably smaller, which likely means the motor powering the autofocus isn’t as large as the one in the Shoten adapter
