Canon M48 Adapter

Description

A Canon EOS (EF/EF-S mount) to M48 adapter for connecting Canon DSLR cameras to telescopes and accessories with M48×0.75mm threading. The camera side features a secure Canon bayonet mount while the telescope side provides standard M48 threads.

Use this adapter to attach your Canon DSLR directly to a field flattener, focal reducer, or telescope back-focus port for prime-focus astrophotography. Compatible with all Canon EOS cameras that use the EF or EF-S mount (not RF mount — see our Canon RF adapter for mirrorless models). The adapter maintains the correct flange distance for infinity focus through the telescope.
