Sony has today introduced two new full-frame lenses for their E-mount camera system, the FE 70-300mm F4.5-5.6 G OSS telephoto zoom and 50mm F1.8 prime lens. The new FE 70-300mm F4.5-5.6 G OSS zoom lens represents the first Sony α E-mount lens to reach a 300mm focal length, featuring high resolution. The new 50mm F1.8 prime lens is compact, lightweight and affordably priced.

Sony's longest reaching E-mount lens to date, the new FE 70-300mm F4.5–5.6 G OSS telephoto zoom lens (model SEL70300G) features four aspherical glass elements, two ED (Extra-low Dispersion) glass elements and Sony's Nano AR coating, which all work together to suppress spherical aberration, distortion, and chromatic aberration.

The new telephoto zoom lens also features great close-up performance, with a minimum focusing distance of less than 3 feet (0.9m) and a maximum magnification of 0.31x, making it a great choice for tele-macro photography.

The zoom lens includes built-in Optical SteadyShot image stabilization that helps to reduce camera shake. Additionally, the new SEL70300G model has a linear actuator that allows it to achieve fast, smooth and quiet autofocus and is also dust and moisture resistant.

Weighing in at less than 7 oz (192 g), the new FE 50mm F1.8 "normal" prime lens (model SEL50F18F) blend performance, compactness and value.

The lens features a new optical design with an aspherical element that compensates for all forms of aberration. Additionally, it has a circular aperture with a maximum of F1.8, producing beautiful 'bokeh' in images that allows the subject to stand out against a smoothly defocused background. For extended durability, the new prime lens is built with a solid metal mount.

The FE 70-300mm F4.5 – 5.6 G OSS telephoto zoom lens will be available in May for about $1,200 US and $1,700 CA, respectively.

The new FE 50mm F1.8 prime lens will also be available in May for about $250 US and $350 CA, respectively.
