What's the best body to adapt the Meyer-Optik Trioplan 100mm f/2.8 (Exakta) onto?

Two strong destinations. First choice: a Canon RF body via a generic mechanical adapter ring (multiple vendors) preserves the most of the Meyer Trioplan 100 f/2.8'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 Meyer Trioplan 100 f/2.8 is adapted onto another body?

No — adapters in our catalogue route the Meyer Trioplan 100 f/2.8 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 Meyer Trioplan 100 f/2.8's in-lens image stabilization still work through an adapter?

The Meyer Trioplan 100 f/2.8 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

Meyer-Optik Görlitz's famous 'bubble bokeh' lens — the three-element Cooke-triplet design renders specular highlights as crisp soap-bubble circles, which made the vintage Trioplan 100 a cult adapter lens (and prompted a modern reissue decades later). Manual focus, preset aperture. A 100 mm short tele on full-frame mirrorless; adapts with infinity via a glass-less Exakta 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.
