The lens’s 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 F4 ensures you won’t 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 F4 achieves an astounding MOD of 0.19m (7.5in) and maximum magnification ratio of 1:4.6 at the wide end, and 0.3m (11.8in) and maximum magnification ratio of 1:3.8 at the 50mm end. With a working distance of around 5.7cm (2.3in) 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 F4 is compatible with the dedicated TAMRON Lens Utility software (for PC and Android™ ² OS) that was developed in-house by TAMRON³. TAMRON Lens Utility lets users change lens settings, assign camera body functions, and update to the latest firmware⁴ 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 providing a more personalized and fulfilling shooting experience.

Every individual part of the lens has been re-examined, right down to the fine details, resulting in an enhanced design that updates both operability and the ergonomic considerations. The surface of the lens exterior is shiny and glossy black. Improved abrasion resistance makes the lens harder to scratch and resists fingerprints. Additionally, the grip performance has been improved. The smooth curved, glossy surface of the brand ring creates a dignified appearance with a design that signifies functional beauty and high quality.

Great things come in compact packages! This lineup* includes other lenses that share the same filter diameter of 67mm. Lenses in this series feature small and light designs ideal for pairing with mirrorless cameras. As well as providing excellent portability, the compactness can save money, too; costly Polarizers, ND and other filters can be used interchangeably.
