Metabones just announced a new Canon EF to Sony NEX plus a all new range of speed booster ULTRA adapters.

The ULTRA is featuring a new optical design incorporating ultra-high index tanatalum-based optical glass to achieve extraordinary optical performance with improved corner sharpness, distortion and reduced vignetting.

The ULTRA (like its original model) will turn any APS-C sensor into an equivalent full frame one with 1 stop gain in brightness.

Here are the key features (taken from metabones press release):

Increase maximum aperture by 1 stop.
Increase MTF.
Makes lens 0.71x wider.
Advanced 5-element/4-group optical design incorporating ultra-high index tanatalum-based optical glass by Caldwell Photographic in the USA (patent pending).
Electronic integration of aperture diaphragm, controlled by or from the camera body.
Partial autofocus support for late-model (post-2006) Canon-brand lenses.
Powered by camera body. No external power source required.
High performance 32-bit processor and efficient switched-mode power supply.
The tripod foot is detachable and compatible with Arca Swiss, Markins, Photo Clam ball heads.
