Thus, so far AF is an experimental feature. Not all Contax 645 lenses support AF (See the
table in part 1. Note: The list of lenses supporting AF may expand after future firmware
upgrades). The speed and accuracy of AF may not satisfy you. If you can’t accept it, please use MF
instead.
Currently only AF-S is supported. If you set the camera to AF-C mode, the lens may keep
hunting and fail to focus.
If possible, half press the shutter release button and let the lens focus for several times may
help improving AF accuracy. And remember, at any time when you feel AF is not working properly,
you may reset the adapter and the lens by playing back a photo and then setting the camera back
to the shooting mode again.

Firmware upgrading
Please follow these steps to upgrade your adapter.
1)
Download firmware file from Fringer’s website (see README.EN.pdf on adapter’s root
directory for the URL). For example, C6GF_200.BIN means Contax645-GFX adapter V2.00.
2)
Get the adapter off the camera. Do not connect G.CAP (if provided), either. Make sure
not to
connect the adapter with the computer while it is installed on a camera body
.
3)
Plug the Micro USB cable to the port inside the tripod mount of the adapter. Be careful! Mind
the
direction
and
do not push too hard
. Or you
may damage the Micro USB port
of the
adapter!
4)
Connect the other end of the cable to a USB port of your PC or MAC. Then a mobile drive
named ‘FRINGER’ emerges. Open ‘VERSION.TXT’ on that drive and check current firmware
version (the line begins with ‘Version:’).
5)
If upgrading is needed, copy the downloaded firmware file to the drive named ‘FRINGER’.
Then eject the drive. Ejection is a mandatory step for Macs and an optional step for PCs.
Ignore any error messages about the drive. Wait for more than 10 seconds. Then disconnect
the adapter with the computer.
6)
Reconnect your adapter with the computer. Check VERSION.TXT again and make sure its
firmware version has changed to the new one.
Note: Do not copy files other than firmware provided by Fringer’s official website to the
adapter.
