Sony has announced that it will be unlocking the keys to its popular NEX camera models (i.e., the E-mount specifications) and allow third-parties to develop lenses for the system.  What’s more, Sony won’t charge them a dime.

Given the initial popularity of cameras like the NEX-5 and NEX-VG10, I would expect to see plenty of lenses down the road from the likes of Sigma and others.  In fact, Sony is touting the endorsement of the move by Sigma, Zeiss, Cosina, and Tamron.

No specifics on what glass will be the first on store shelves, but my guess is that these guys already have stuff in progress.

Any Sony NEX owners out there with a wish-list of lenses from Zeiss, Sigma, etc.?
