Some interchangeable lens standards have been around for ages. Others, however, are rather more modern contrivances, and Sony's E-mount definitely falls in that latter category. We've seen it hit HD camcorders as well as the NEX-3 and NEX-5 compacts, but so far the greatest selections of lenses we've yet seen has come courtesy of a simple adapter. Sony wants that to change, releasing the "basic" specifications for its E-mount interchangeable lens system and doing so for free, a move that lens makers like Carl Zeiss and Sigma have all lauded -- though none went so far as to say they'd actually start making this particular flavor of glass. Oh, and the specs for the NEX-5 Lego viewfinder? Still totally free.
