Sony A7 and A7R have been recently launched by the Japanese giant and they were very well received by customers all over the world due to its full frame sensor that offers almost the same image quality as Nikon's D800 and D800E digital SLRs.
A while back we were showing you a video regarding the possibility of Sony A7R cameras to use Contax G lenses via a small adapter from Deo Tech. The adapter allows you to use any Contax G lens at its fullest potential including full AF support.
According to SonyAlphaRumors, Deo Tech is preparing a 3rd generation full frame adapter that will enable any Sony A7/A7R mirrorless camera owner to mount and use any Canon EF lens available on the market.
The new adapter will also come with built-in Bluetooth technology that will allow you to update your DEO adapter's firmware with ease. This is great news for Sony A7/A7R users and will probably even boost camera sales a bit.
