Just moments after two German lens makers entered the Micro Four Thirds consortium, an interchangeable-lens camera (ILC) standard used in Panasonic and Olympus cameras, Sony has announced that it will open up the "basic specifications" for its E-mount.
The E-mount is used in the company's NEX range of camcorders and is a completely different mount to that used by the Micro Four Thirds system. Sony has said it will open up the specifications without a fee, which means other manufacturers can make lenses and accessories for the system.and
It's a big move from the company, given the competitive nature of the ILC market and that Sony currently only has three E-mount system bodies on the market. The other major ILC camera maker, Samsung, has a range of third-party lenses available for use.
Manufacturers which have received the basic specifications include Carl Zeiss, Cosina, Sigma and Tamron.
