The 50mm f/1.4 EX DG HSM from Sigma is a standard lens with large maximum aperture of f/1.4.

The lens is designed for use with DSLRs and effectively becomes an 80mm medium telephoto lens on digital cameras with APS-C size image sensors.

The optimum optical design and molded glass aspherical lens elements provide correction for all types of aberrations.

The super multi-layer lens coating, for example, reduces flare and ghosting.

The optic has a minimum focusing distance of 45cm and has maximum magnification of 1:7.4.

Sigma adds that the lens incorporates a HSM (Hyper Sonic Motor), which ensures a quiet and high-speed AF as well as full-time manual focus override.

It will come with Sigma AF, Canon AF, Nikon AF, Sony AF and Pentax AF fittings.

No price as yet or availability but we'll keep you posted.
