Mount Adapters page 11

What is a mount adapter?

A mount adapter is an extension ring with which lenses and filters with different mounts can be connected to the body of your camera. Thanks to the large offer of adapters, almost all types of lenses can be attached to other camera bodies. In contrast to an extension ring, the mount adapter is not hollow inside and can transfer complete information between lens and camera via the contact points.

Focus and autofocus

With a mount adapter, it is possible to keep the focus of your lens at the right level and also to use the autofocus function of the camera. Since a glass plate is mounted in the adapter, distortion can be prevented from occurring and the vignetting is limited. In addition, light loss is prevented from occurring when you would otherwise have to work with several lenses.
