Designed for using Canon EF and EF-S lenses with Sony full frame and APS-C camera bodies, the Metabones Smart Adapter Mk IV maintains electronic communication allowing for fast autofocus and lenses with optical image stabilization. That means you have the option to use the Sony camera’s sensor shift image stabilization, optical stabilization via the Canon lens, or both at the same time! This adapter also supports Canon CN-E lenses with power zoom, autofocus, and auto-iris. The Smart Adapter is also seriously smart. You may notice the first couple autofocus attempts with this adapter may not be perfectly accurate. This is because these autofocus attempts are used to calibrate the lens being used. After the lens, adapter, and body have gotten to know each other they’ll work great. Think of those first couple images as a team building exercise. Visit Metabone’s website for full compatibility charts.

IMPORTANT: This lens adapter has some trade-offs in autofocus performance relative to native-mount lenses. You will almost certainly not be able to use any continuous focus modes with this adapter. If you have questions about this, please contact us and we'll be happy to help.
