Decision tools · Mount Adapting

Will my lenses fit a different body?

Pick the mount your glass is on and the body you're thinking of moving to. We work out whether a plain adapter gets you there, show the millimetres it turns on, and say what it does to your framing.

Answers focus and framing. Autofocus, aperture control and whether an adapter is actually made are separate questions.

Your pairing

Four Thirds glass on a Canon EF body

Optics
Verdict
Four Thirds38.67mm
− Canon EF 44.00mm
Room for an adapter-5.33mm

Only with corrective optics

Canon EF sits 5.33mm further from the sensor than Four Thirds. An adapter can only add distance, never remove it, so infinity focus is impossible without corrective glass in the adapter — which costs sharpness and usually a stop of light.

Coverage & framing. Four Thirds lenses are built for a Micro Four Thirds imaging circle, which is smaller than Full frame. Expect heavy vignetting or a forced crop on a Canon EF body.

No adapter listed yet. We don't stock an adapter for this pairing; the verdict above is the flange-distance arithmetic.

NativeNative fitSame mount. The lens bolts straight on — no adapter, nothing lost.
AdapterWorks with a plain adapterYou still need an adapter, but only a plain one — a hollow metal spacer with no glass in it. Focus and image quality are unaffected.
ThinNeeds a thin adapterThe two mounts sit almost the same distance from the sensor, so any adapter has to be wafer-thin or flush. These exist for common pairings and often don't for rare ones.
OpticsOnly with corrective opticsA plain adapter cannot work — it would have to remove distance, which is impossible. Only an adapter with corrective glass inside will focus to infinity, and that costs sharpness and usually a stop of light.

What this does and doesn't tell you

  • It answers focus and framing: whether a plain adapter reaches infinity, and what the sensor does to your field of view.
  • A dot (•) in a cell means we list at least one adapter for that pairing; pick the cell to see them. Elsewhere it doesn't promise an adapter is made — rare combinations often have none.
  • Electronic contacts, autofocus and aperture control are separate questions. Most adapters for legacy glass are fully manual.
  • On SLR-to-SLR pairings, mirror clearance can stop a lens fitting even when the numbers work.
