Contax 645 - Flash Bracket
When using the Waist Level Finder, TTL Auto Flash is preserved by using the accessory Flash Bracket.
A quick-shoe adapter and camera release are situated at the top of the grip, while a remote socket release is built-in.
When connected to the camera via a cable, the photographer can release the camera on the flash bracket using the left hand, while the right hand is free for adjusting shutter speed and other controls.
