Hong Kong-based lens maker SLR Magic has announced a 23mm F1.7 lens for Sony NEX cameras as part of its 'HyperPrime' range. The E-mount lens offers a 35mm equivalent field-of-view and a minimum focus distance of 0.15m to offer a good degree of control over depth-of-field. It becomes the company's forth E-mount lens (in addition to the recently announced 35mm F1.7, 50mm F0.95 and 28mm F2.8), which it claims it is the fastest APS-C lens of this focal length. The company is seeking volunteers to provide feedback, who will be able to buy the lens at a discounted price.

Press Release

NEW: THE SLR Magic HyperPrime 23mm F1.7

Hong Kong, China (December 8, 2011)  - SLR Magic expands the E-mount lens lineup with the new SLR Magic HyperPrime 23mm F1.7 wide angle lens. With this latest addition, the portfolio of lenses for the E-mount system is now comprised of four focal lengths. The world's fastest interchangeable camera lens with APS-C coverage in this focal length, the SLR Magic HyperPrime 23mm F1.7 will be available in January 2012.
The field of view of this new HyperPrime Lens corresponds to a 35mm lens in 35mm format and this fast wide angle of view opens up many new creative composition opportunities, particularly in the fields of candid, street, and landscape cinematography and photography. A minimum focus distance of 0.15m allows for pleasing defocused backgrounds. Additionally, a fast max aperture of F1.7 makes the SLR Magic HyperPrime 23mm F1.7 ideal for available-light photography. 
We place our highest priority in the development of all HyperPrime lenses to fulfill the demands of professional cinematographers and photographers. The design and build of the SLR Magic HyperPrime 23mm F1.7 is solid and reliable.
The SLR Magic HyperPrime 23mm F1.7 will be available from authorized SLR Magic dealers by the end of January 2012.

SLR Magic is currently looking for volunteers to test this lens at a special price. If interested:
