17-50mm f/4 VXD: your world expanded
The 17-50mm f/4 Di III VXD (Model A068) covers a versatile zoom range from ultra-wide through standard focal lengths - no need to switch lenses. From landscapes containing dynamic compositions of sprawling vistas to casual snaps and portraits in the standard range, you'll be amazed by the rich variation that's possible with a single compact lens. The angle of coverage near the 50mm end closely approximates normal human vision. Whats more, this zoom lens provides an f/4 aperture throughout the zoom range even when you zoom in or out, making it ideal not just for still images but also video shooting. The 17-50mm f/4 will dramatically expand your range of possible expression, paving the way to all-new creative photographic experiences.
The optical construction of the 17-50mm f/4 consists of 15 elements in 13 groups. With the precise arrangement of special lens elements, including three LD (Low Dispersion), one GM (Glass Molded Aspherical) 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 f/4 wide-open aperture get you close to that perfect shot.
The 17-50mm f/4 weighs just 460g and is a compact 114.4mm 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 minimizes changes to the centre of gravity while shooting. Its easy to maintain framing while shooting still images and video, and it can be easily balanced when paired with a video rig or gimbal stabilizer. The highly portable 17-50mm f/4 features Moisture-Resistant Construction and employs a Fluorine Coating on the front and back lens surfaces, providing durability in natural environments such as trekking, camping, and other outdoor activities, and making it more convenient to clean the lens when necessary.
The lenss AF drive uses the VXD (Voice-coil eXtreme-torque Drive) linear motor focus mechanism. The AF drive features high-speed operations and achieves positional accuracy in miniscule 0.005mm increments. Equipped with high-speed and high-precision autofocus among the best in its class, the 17-50mm f/4 ensures you wont miss a shot when out and about or traveling. With fast and accurate focusing on moving objects, the lens can reliably track subjects whose movements are difficult to predict such as small children and pets, making it great for shooting video. Additionally, thanks to quiet operation during AF, the lens can be used with peace of mind when shooting still images or video in noise-sensitive settings like school plays and weddings.
The 17-50mm f/4 achieves an astounding MOD of 0.19m and maximum magnification ratio of 1:4.6 at the wide end, and 0.3m and maximum magnification ratio of 1:3.8 at the 50mm end. With a working distance of around 5.7cm at the 17mm end, you can practically get as close to the subject as you wish. This allows you the flexibility to shoot in cramped places such as small rooms or inside a camping tent, without needing to reposition. It also lets you enjoy compositions that make use of beautiful bokeh and unique angles.
The 17-50mm f/4 is compatible with the dedicated Tamron Lens Utility software (for PC and Android OS) that was developed in-house by Tamron. Tamron Lens Utility lets users change lens settings, assign camera body functions, and update to the latest firmware when necessary. In addition, when using the Mobile version, functions unique to mobile version can be operated remotely without touching the lens. Users may customize functions for various still photography and videography shooting styles, thereby pr
