Camera lens-mount × adapter compatibility

Every [mount A] to [mount B] adapter, with autofocus, IS, and aperture honestly labelled.

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?

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.
