The Adapter for Canon EF Lens to Sony NEX Mount Camera (with Iris Control) from FotodioX allows a Canon EF lens to attach to a Sony NEX camera body. Adapting a larger format lens to a smaller format sensor provides optical as well as practical advantages. The smaller image field helps minimize the effects of lens distortion and aberration by using the center or "sweet spot" of the larger lens' image circle, thus providing edge-to-edge sharpness.
Although the lens will fit physically, automatic diaphragm, auto-focusing, or other electronic functions will not operate correctly while using this adapter. Manual or aperture priority mode must be used when this adapter is attached. Its all-metal design and polished surface provide smooth mounting and long lasting performance.
- This adapter also has a built in iris which allows for some degree of control over the light coming in from the lens. Canon EOS lenses use an electronic aperture which will not function with an adapter, the built-in clickless iris control enables the lens to still be used with some functionality.
