Fringer Contax 645 – Fujifilm GFX50s
Smart adapter user’s manual
(v2.0)
Important!
Please read this manual carefully before using the adapter. Be noted:
The activation process is
NOT required anymore
. You can use the adapter on
your camera directly. Thus, G.CAP (the device for activation) is no longer
provided with the adapter.

General descriptions
This adapter is compatible with Contax 645 and Fujifilm G mount protocols. It can control
lens’ aperture electronically, auto focus (some of C645 lenses only) and support Exif recording.
All C645 lenses are supported. See the table below.

The adapter has been tested on GFX50s camera body. Theoretically it may support future G
mount bodies.
Please be noted that so far AF is an experimental feature. On one hand, not all lenses support
AF. On the other, even for those lenses supporting AF, the performance may not be good enough
for you. If the AF speed or accuracy can’t satisfy you, please change to MF mode. All lenses can
work under MF mode.
2.
Installation and activation
I suggest connecting the lens with the adapter first. After that, install the adapter onto the
body. If you need to separate the lens from the adapter while the adapter is connected with the
body, you must turn off power first.
Although Fujifilm G mount is not an open design, we tried our best to make C645 lenses
