Samyang 800mm f/8 Mirror MC (T-mount) — adapter compatibility and body matches
The Samyang 800mm f/8 Mirror MC (T-mount) sits on the T-mount flange geometry (55 mm) — below is every body mount it adapts onto, the autofocus / IS / aperture-control level you should expect, and the specific adapter SKUs that ship the path.

Background & adapter context
A current-production catadioptric 800 mm reflex (also badged Rokinon / Walimex / Bower) sold in interchangeable T-mount — representative of why T-mount survives in 2026: extreme reach for astronomy, wildlife and the Moon at a fraction of a native super-tele's price and weight. Fixed f/8, manual focus, rear drop-in filters, multi-coated optics. The one-lens-many-bodies T-X design means the same lens moves between a Nikon Z, a Sony E and an EF DSLR with only a ring swap; infinity is preserved on all of them.

About the T-mount (T2) mount
M42 × 0.75 thread originated by Tamron in 1957 (and later standardised as T-2 in 1962). Not a camera-mount in the conventional sense — T-mount lenses (Tamron Adaptall predecessors, Vivitar Series 1 zooms, Soligor primes, modern telescope eyepieces, Samyang manual primes) screw into a T-X adapter ring sized for the target body (T-Nikon F, T-Canon FD, T-EF, T-Sony E, T-RF, etc.). The lens's own flange-to-thread surface is 55 mm; the T-X adapter accounts for the body's actual flange. Still actively produced for astronomy and machine-vision optics.
Common questions
- What's the best body to adapt the Samyang 800mm f/8 Mirror MC (T-mount) onto?
- Two strong destinations. First choice: a Canon EF body via a generic mechanical adapter ring (multiple vendors) preserves the most of the Samyang 800 f/8 Mirror's native behaviour (autofocus, in-lens IS where present, electronic aperture). Second choice: a Canon EF-S body via a generic mechanical adapter ring (multiple vendors) — solid fallback when the first body family is unavailable. The /matrix and /picker pages let you compare every feasible adaptation side-by-side.
- Will autofocus work when the Samyang 800 f/8 Mirror is adapted onto another body?
- Not through an adapter — the Samyang 800 f/8 Mirror's T-mount mount predates electronic AF, or no body in our dataset preserves AF for adapted T-mount lenses. Focus relies on the body's manual aids (focus peaking, magnify-to-focus).
- Does the Samyang 800 f/8 Mirror's in-lens image stabilization still work through an adapter?
- The Samyang 800 f/8 Mirror has no in-lens IS / VR / OS unit — there's no in-lens stabilisation to pass through. Bodies with IBIS (most modern mirrorless) still stabilise the captured frame, but stabilisation is body-side only.
