What's the best body to adapt the Canon FD 135mm f/2 onto?

Two strong destinations. First choice: a Canon RF body via the Fotodiox FD-RF preserves the most of the FD 135 f/2's native behaviour (autofocus, in-lens IS where present, electronic aperture). Second choice: a Sony E (incl. FE) body via the Fotodiox FD-NEX — 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 FD 135 f/2 is adapted onto another body?

No — adapters in our catalogue route the FD 135 f/2 through a mechanical path on the best-supported body (Canon EF). Focus is fully manual; rely on the body's focus peaking and magnify-to-focus aids to nail focus.

Does the FD 135 f/2's in-lens image stabilization still work through an adapter?

The FD 135 f/2 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.

Background & adapter context

Full-frame coverage. New FD short telephoto — not officially L-designated (no red ring on the barrel) but widely regarded as L-class in optical quality; the direct ancestor of the EF 135mm f/2L USM, which inherited the basic optical layout. Sharp wide-open, beautifully separated subject rendering at f/2. The most-adapted FD telephoto onto modern mirrorless after the FD 85 f/1.2 L. Mechanical FD-to-FE / RF / MFT adapters handle the weight and rear-element clearance without issue.

About the Canon FD mount

Canon's manual-focus 35 mm SLR mount, introduced on the F-1 in 1971 and produced through 1992 — Canon's last fully-mechanical bayonet before the all-electronic EF transition in 1987. Two mounting generations share the same lens-to-flange dimensions: the original FD (1971-1979) uses a breech-lock collar (a rotating ring at the lens base, no twisting the lens body itself), and the New FD (1979-1992) switched to a conventional bayonet twist while preserving the same 42.0 mm flange and 48.0 mm throat. Pure mechanical: aperture-priority and shutter-priority both communicate via mechanical linkages, no electrical contacts in any iteration. The FD L line — FD 50 mm f/1.4 S.S.C., FD 85 mm f/1.2 L, FD 135 mm f/2 L, FD 200 mm f/1.8 L, FD 300 mm f/4 L — and the legendary FD 55 mm f/1.2 S.S.C. Aspherical remain the most sought-after FD glass for mirrorless adaptation. The 42 mm flange is shorter than EF / Nikon F / Pentax K / Minolta SR, so FD-to-EF / FD-to-Nikon-F (without a corrective optic) cannot reach infinity — FD glass is mirrorless-only territory in practice.
