Canon Working On New Generation of Lens Adapters for Mirrorless Cameras
It’s look like Canon is working on new generation of lens Adapters. If you look at the details translated from Japanese its says “second light amount adjustment unit “. That may indicate, the upcoming lens adapter may come with built-in advance iris control while using EF / EF-S Lens to EOS M Mount.
Take a look at the details below.
An adapter is attachable between an interchangeable lens including a first light amount adjustment unit capable of changing a passing area of image pickup light, and a camera main body including an image pickup element. The adaptor includes: a second light amount adjustment unit capable of changing transmittance of the image pickup light by using a change in a physical property; and a controller controlling the second light amount adjustment unit. In image pickup mode, the controller controls the transmittance in the second light amount adjustment unit depending on an operating amount of an operation unit by a user to adjust a light amount, and in the image pickup mode, the controller converts an instruction, transmitted toward the interchangeable lens from the camera main body, to drive the first light amount adjustment unit, into a drive completion signal, and transmits the drive completion signal to the camera main body.

캐논이새로운 EOS M마운트어댑터를작업중인것으로보이는 특허라고하네요. EOS M마운트어댑터가더좋아진다면 캐논풀프미러리스바디가더욱쓸만해질것같기도하네요.
