Sony NEX Aperture Control for Canon EOS Lenses
Conurus has developed the electronic interface between a Sony NEX body and a Canon EOS / EF lens. This allows the aperture of a Canon EOS lens to be controlled by the Sony NEX. Normally Canon EOS lenses are at minimum aperture when they are not on a Canon body. The lenses do not have aperture rings and when used with an adapter on a Sony NEX body , the aperture cannot be changed. This Conurus system changes that. Hopefully they can miniaturize the system.
