Sony introduces new zoom lens FE 12-24 mm F2.8 GM

Sony is introducing a fourth G Master lens -- the very wide-angle zoom lens FE 12-24 millimetre F2.8 GM offers a constant aperture of F2.8 and a minimum focusing distance of 0.28 metres over the entire zoom range. A "floating focus system" divides the lens´ focus group into two independently controllable groups to maximize close-up performance as well as sharpness at any distance.

The E-Mount lens uses four original XD (Extreme Dynamic) linear motors, two for each focus group of the lens, which according to Sony are extremely fast and quiet. New control algorithms are designed to optimise the responsiveness of the XD linear motor system and ensure perfect synchronisation between the two focus groups. For manual operation, there is an adjustable focus hold button, a focus adjustment switch, a zoom ring and a focus ring.
