What's the best body to adapt the Steinheil Auto-Quinon 55mm f/1.9 (Exakta) onto?

Two strong destinations. First choice: a Canon RF body via a generic mechanical adapter ring (multiple vendors) preserves the most of the Steinheil Quinon 55 f/1.9's native behaviour (autofocus, in-lens IS where present, electronic aperture). Second choice: a Canon FD 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 Steinheil Quinon 55 f/1.9 is adapted onto another body?

No — adapters in our catalogue route the Steinheil Quinon 55 f/1.9 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 Steinheil Quinon 55 f/1.9's in-lens image stabilization still work through an adapter?

The Steinheil Quinon 55 f/1.9 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

Steinheil München's fast standard for Exakta — the Auto-Quinon's f/1.9 speed and distinctive out-of-focus rendering make it a collector favourite for adapted character portraits. Manual focus; the 'Auto' denotes the spring-loaded automatic-aperture lever that Exakta bodies actuated at the moment of exposure. Adapts to mirrorless with infinity via a glass-less ring.

About the Exakta mount

The world's first practical 35 mm SLR mount, introduced by Ihagee Dresden in 1936 on the Kine Exakta. Bayonet interface with a left-handed front-mounted shutter release. Pure mechanical — auto-aperture via external lever, no electrical contacts ever. Carl Zeiss Jena (Biotar, Tessar), Schneider Kreuznach (Xenon), and Meyer-Optik (Trioplan, Primotar) built the most-collected glass for it. Discontinued in 1972 with Ihagee's collapse, but Exakta lenses adapt cleanly onto every mirrorless mount thanks to the modest 44.7 mm flange.
