Common questions about manuals, registration, and support for this brand.
Check the official Fringer website for documentation matching your adapter model. The C645-GFX II manual specifically directs users to https://www.fringeradapter.com/contax-645-to-fujifilm-gfx#3 for downloads.
Follow your model's manual. The documented procedure uses a PC or Mac and a USB data cable: remove the adapter from the camera, connect it to the computer, copy the correct official firmware to the FRINGER drive, then check VERSION.TXT after the adapter reconnects.
Autofocus depends on the camera, lens and adapter firmware. Check your model's tested and optimized lens list. Some lenses require manual focus, and cameras without phase-detection autofocus may perform more slowly.
Contact the seller or email fringeradapter@163.com. The C645-GFX II manual specifies a one-year limited warranty; check your own product documentation for applicable terms.
Try another USB data cable. Charging-only cables cannot transfer firmware files. Confirm the connection procedure and cable type in your adapter's manual.
