The excellent close-range shooting performance provides an MOD2 of 0.19m (7.5in) at the wide end and 0.3m (11.8in) at the tele end. What’s more, the constant F4 aperture throughout the whole range makes it ideal not just for still images but also video shooting. The 17-50mm F4 will dramatically expand your range of expression, paving the way to all-new creative photographic experiences.

The optical construction of the 17-50mm F4 consists of 15 elements in 13 groups. With the precise arrangement of special lens elements, including three LD3, one GM4 and two hybrid aspherical lens elements, chromatic and other aberrations are effectively suppressed. The resolving power across the entire frame with clarity and sharpness, and full use of the rich bokeh delivered by the F4 wide-open aperture get you close to that perfect shot.

The 17-50mm F4 weighs just 460g (16.2oz) and is a compact 114.4mm (4.5in) long, a size that's well-balanced even when attached to a Sony mirrorless camera body. The lens has a fixed barrel length and internal zoom mechanism that make it easy to maintain framing while shooting still images and video, and easily balanced with a video rig or gimbal stabilizer. The highly portable 17-50mm F4 features Moisture-Resistant Construction and Fluorine Coating on the front and rear lens surfaces, providing durability in natural environments.
