Can I make this work with my camera?

Pick the lens mount and the camera mount. We'll tell you whether they fit natively, with an adapter, with catches, or not at all, and show adapters for sale at Canadian dealers.

Shortcut: type a camera or lens we track

Lens mount Camera mount

How this works

Every mount puts the lens a set distance from the film or sensor (the flange distance). An adapter is a spacer that makes up the difference, so it only works when the lens mount's distance is longer than the camera's. That's why most older SLR lenses adapt to mirrorless cameras, but mirrorless lenses can't go on SLRs. Autofocus and electronic aperture control need an adapter with electronics.
