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.

Fujifilm X glass on a Micro Four Thirds body

Optics
Verdict
Fujifilm X17.70mm
− Micro Four Thirds 19.25mm
Room for an adapter-1.55mm

Only with corrective optics

Micro Four Thirds sits 1.55mm further from the sensor than Fujifilm X. 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. The lens covers more than the sensor needs, so the body crops into the frame — roughly 1.3×. A 50mm frames like a 66mm would on APS-C.

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.
  • It doesn't promise an adapter is actually manufactured for your pairing. 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.
