Camera lens-mount × adapter compatibility

EF to RF, F to Z, A to E — every camera lens-mount adapter, honestly labelled for autofocus, IS, and aperture.

One scannable cross-brand matrix for the question vendor pages and forum threads never quite answer: I have this body and these lenses — which adapter actually works, and what do I lose?

The whole game in one axis: flange focal distance

Every mount sits a fixed distance from the lens flange to the sensor. Mirrorless mounts cluster below 20 mm; SLR mounts bunch around 44–46 mm. That gap is exactly the room a mechanical adapter fills — which is why almost any SLR lens drops onto a mirrorless body, while the reverse usually needs corrective glass or is impossible. All 27 mounts in the dataset, to scale:

Common questions

Can I use Canon EF lenses on a Canon RF body?
Yes. Canon's official EF-EOS R adapter preserves full autofocus, image stabilization, and electronic aperture control on every EF lens released since 1987. EF flange (44.0 mm) is significantly deeper than RF (20.0 mm), leaving exactly the 24 mm of clearance the adapter needs without any optical element.
Will Nikon F lenses autofocus on a Nikon Z body?
It depends on the lens. With the Nikon FTZ II adapter, AF-S and AF-P lenses (those with built-in focus motors) keep full autofocus. Older AF-D / AF screw-drive lenses lose autofocus because the Z mount and FTZ have no screw-drive coupling — you can still focus them manually with focus confirmation.
Why won't M42 lenses reach infinity focus on every body?
M42's flange distance is 45.46 mm. To preserve infinity focus on a DSLR with a similar flange (Canon EF 44.0 mm, Pentax K 45.46 mm, Nikon F 46.5 mm), the adapter must be either thin enough or, in Nikon F's case, contain a corrective optical element. Mirrorless bodies (RF, Z, E, X, MFT, L-Mount) have flange distances well below 27 mm, so a plain mechanical adapter restores infinity focus easily.
Does a Speed Booster preserve autofocus?
The Metabones Smart Adapter family preserves contrast-detect AF on most Sony E and MFT bodies for Canon EF lenses, with phase-detect AF supported on select PDAF-capable bodies. AF speed is typically slower than native. Focal reducers from other brands (Viltrox, Fotodiox) vary — always check per-body and per-lens compatibility before purchase.
Is there an A-mount to E-mount adapter that preserves autofocus?
Yes — the Sony LA-EA5. It carries its own SSM (ultrasonic) drive motor inside the adapter, so screw-drive Minolta / Sony A-mount lenses keep autofocus on PDAF-capable E-mount bodies (A1, A7R V, A7 IV, A6700, A7C II / R, and the latest A9 / FX line). SSM and SAM lenses (those with their own in-lens motors) get full AF on every E-mount body via the LA-EA5. Older LA-EA3 and LA-EA4 adapters still work for SSM/SAM lenses but don't drive screw-drive AF.
What's the best Leica M to Sony E adapter for a rangefinder lens?
For pure manual focus, any reputable mechanical M-to-E ring works — Voigtländer VM-E Close Focus II, Novoflex MFT/LEM, Metabones Mark V, K&F Concept. M flange (27.8 mm) is deeper than E (18 mm) so a 9.8 mm spacer reaches infinity with no glass. For autofocus on an M lens, the Techart LM-EA9 is the only widely-available option: a piezo motor inside the adapter shifts the entire lens forward and back ~4.5 mm to focus. AF is slower than native but works on most lenses ≤ 135 mm and under 750 g.
Can I use Olympus OM lenses on a Micro Four Thirds body?
Yes, with a mechanical adapter — Olympus's own MMF-3 is weather-sealed; cheaper rings from Fotodiox, K&F Concept, and Urth work fine for unsealed setups. OM flange (46.0 mm) is deep enough above MFT (19.25 mm) that a 26.75 mm spacer restores infinity focus without glass. Every Zuiko OM lens is manual focus with a mechanical aperture ring, so you keep stop-down metering and focus-confirm on the body's EVF — but autofocus, electronic aperture, and IS pass-through are not available (the lens has no electrical contacts to pass).
