Sony has unveiled what they are calling the “world’s widest full-frame constant f/2.8 lens at 12-24mm” the G Master FE 12-24mm.
The lens groupings include: 3 Extreme Aspherical (XA) elements, 1 regular aspherical element, 3 Extra-Low Dispersion (ED) elements and 2 Super ED elements that work together to minimize astigmatism, coma and field curvature to create incredibly sharp images from the center, right out to the image edges.
The autofocus system utilizes a floating focus mechanism to divide the lens’s focus group into two independently controllable groups to help minimize aberrations across the entire zoom range.
The system itself is powered by 4 high-speed, high-thrust, Extreme Dynamic (XD) liner motors, 2 for each of the lens’s focus groups.
On the outside of the lens there is a focus hold button that will lock focus when recomposing and focus mode switch (auto or manual) both of which are positioned in easy to find locations.
