Conurus and Metabones launch $399 Canon EF to Sony NEX smart adapter

By Dan Chung

Lens adapter maker Metabones and Conurus have developed a smart adapter to allow the use of Canon EF glass on Sony NEX cameras like the FS100, NEX5n and VG20. It gives control of aperture and also apparently image stabilisation too. It is similar to the MTF services adapter which we previously featured this adapter differs in that it uses the camera body’s controls to adjust aperture and does not have an external box or power. It is also much lower cost and could prove a welcome addition for FS100 shooters looking to use EOS lenses – how it actually works for video shooting is still to be seen.

This from their website –

This Smart AdapterTM has the following features:

True electronic integration of aperture diaphragm – let camera automatically choose aperture in P or S exposure modes, or dial in yourself on the camera body in A or M modes.
Powered by camera body. No external power source required.
Wide open button (opposite of depth-of-field preview function) makes manual focusing easy.
