Sony has just introduced three brand new E-Mount prime lenses with extremely compact and lightweight design. The Sony 24mm F2.8 G, Sony 40mm F2.5 G, and the Sony 50mm F2.5 G feature a de-clickable iris, a focus hold button, MF/AF switch as well an aperture click switch.
Users can customize the focus hold button by assigning a preferred function directly from the camera’s menu. Each unit sports dual linear motors for fast and reliable autofocus for both stills and video. Additionally, all three lenses have the same size (68mm diameter x 45mm) and front filter diameter (49mm) while weighing at around 170 g. They are also dust and moisture-resistant which makes them well protected when used in harsh conditions.

The FE 24mm f/2.8 G optical design consists of 9 elements in 9 groups and has 7 aperture blades. Balancing the optics is an XD Linear Motor system that uses two separate focusing motors to deliver especially quiet, precise, and quick autofocus performance.
