Want to use a Nikon lens on a Canon camera? Or a vintage Minolta lens on an Olympus? You need a lens adapter to re-purpose those lenses to work with today’s DSLR cameras.
Adapters are relatively inexpensive and easy to use. They simply mount between the lens and the camera body. It’s important to note that most lens adapters are purely mechanical. They provide a mechanical interface between the lens and camera. As a result, focus and aperture adjustments must be done manually.
