Sigma 50mm 1.4 for Canon in Raffles Place, Central Singapore for sale

Selling the old Sigma 50mm 1.4 (not the 'art' lens). This one is a couple of years old and performing as new. Great quality - brilliant walk around lens and excellent in low light. Used it for a lot of street shooting but good for landscapes too. Priced for a quick sell. Need to buy new furniture so scaling back on the lens collection :(
Overview:
The Sigma 50mm f/1.4 EX DG HSM is constructed with a plastic body and a metal mount. This lens features a distance window with depth of field scale. A nine-blade, maximum aperture of f/1.4 gives the lens the ability to create shallow depth-of-field effects. The optical construction of this lens contains eight lens elements, including one aspherical lens element. This lens uses a front extension focusing system, powered by a ring USM motor. Auto-focus speed of the lens is moderate; it is not as fast as most ring USM lenses. The front of the lens does not rotate, but does extend when focusing. The lens is designed so that the outer body barrel is longer than the inner lens barrel, when the inner lens barrel is at its longest extension. This results in the lens maintaining the same overall length no matter where the point of focus lies.
In a 1.6× body, such as the Canon EOS 7D, it provides a narrower field of view, equivalent to an 80 mm lens mounted on a 35 mm frame body.
