Built-In Aperture Control Speed Booster Focal Reducer Lens Adapter Suit For Canon EF Lens to Micro Four Thirds 4/3 Camera

 

Why need to use speed booster/focal reducer adapter?

It converts full-frame lenses into APS-C lenses. The advantage is to get the full frame field of view onto the APS-C sensor.

Built-In aperture control for adjusting the amount of light let into your camera.

Increase exposure to 1 stop, and you can use faster shutter speed to shoot an image. Works fine, closely combined with the bayonet smooth, like the original lens.
