Hong Kong, China (December 13, 2013)  - SLR Magic expands the micro four thirds lens lineup with the new SLR Magic 17mm T1.6 wide angle lens. With this latest addition, the portfolio of lenses for the micro four thirds system is now comprised of seven focal lengths.
The field of view of this new lens corresponds to a 34mm lens in 35mm format and this fast wide angle of view opens up many new creative composition opportunities, particularly in the fields of interior, architectural and landscape cinematography and photography. Additionally, a fast max aperture of T1.6 makes the SLR Magic 17mm T1.6 ideal for available-light photography.
We place our highest priority in the development on our lenses to fulfill the demands of professional cinematographers and photographers. The design and build of the SLR Magic 17mm T1.6 is solid and reliable.
The SLR Magic 17mm T1.6 will be available from authorised SLR Magic dealers starting end of December 2013.
