A lens adapter is a device to mount lenses made for some type of camera on another camera for which they were not originally designed.
An adapter will receive any lens with one type of lens mount, and attach it to a camera body with another lens mount. In some cases the use of a lens on an adapter changes the distance range or the speed of the lens.

Adapters for autofocus lenses
The type of adapters mentioned above is common to adapt lenses which allow manual focusing and manual aperture control. But some of modern times' electronically refined lenses may be adaptable too.
The main efforts to support full automatic functionality of adapted autofocus lenses were made by the surviving big players in the camera market when they launched their CSC cameras. Most of them created own adapters including electronical translation units for the electrical signals. These devices usually connect the lenses of an older SLR or DSLR system to the newer CSCs of the same camera maker. Thus the new camera types soon become popular among the brand's old fans since their old lenses work with full functionality on the hottest new digital system cameras.
Only a few independent efforts were made, some even to achieve inter-brand adaption of autofocus lenses. Metabones is one maker of such adapters. It offers self-constructed adapters to adapt Canon EF lenses to Sony E-mount and others to attach them to Micro Four Thirds lens mounts, both adapter variants supporting electronical aperture control by means of the camera mount's original lens control signal protocol. The adapter variant for the E-mount even supports electrical focusing for many Canon lenses made since 2006, but according to Metabones`own product description that solution works slowly. To reach more buyers with that limited solution the adapters are also available as wide-angle converters with optics which boost an attached lense's speed significantly. Metabones calls these converter adapters "speed booster".
