Designed to be used with: Dedicated CCD Field Flatteners (175FF, 160FF and 13035FF) and Telecompressor Correctors (175TCC, 160TCC, 155TCC and QuadTCC).
This DSLR Camera Adapter for Canon EOS cameras with its large 1.875" (47.6 mm) inside diameter bayonet minimizes vignetting on full frame sensors by eliminating the restrictive 1.5" (38 mm) diameter standard T-thread interface.
The adapter body is precision-machined aluminum and is anodized black. The bayonet is machined stainless steel, and both the body and the bayonet are baffled and painted flat black on the inside.
The ADATCCEOS will place the camera's sensor at the perfect 80.8 mm distance from the mating surface of CCD Field Flattener and Telecompressor Correctors.
Warning: Be very careful if using filters with any of the TCC Telecompressor-Correctors, as they have very limited clearance to the back optical element. DO NOT stack multiple filters when using the Telecompressor Correctors!
Please note: this adapter can NOT be used with Canon manual-focus 35 mm cameras (series FD and earlier lenses).
This adapter has a net spacing distance of 1.45" (36.8 mm).
