Sony has debuted a new G Master that is destined to become a best seller for Alpha photographers. The new FE 12-24mm F2.8 GM is the world's widest zoom with a constant F2.8 aperture, ideal for shooting ultra-wide shots of landscapes and architecture. The lens features three XA elements, one of which is the largest XA element created for an Alpha lens. This, combined with three extra-low dispersion glass elements help to reduce chromatic aberration and color fringing while also enhancing image clarity. It also features high-performance Linear Motors to ensure that it can keep up with future camera bodies and Nano AR Coating II is used for the first time to help minimize internal reflections and ghosting.
