Ultra-telephoto zoom starts at 50mm
The 50-400mm F/4.5-6.3 Di III VC VXD is an unprecedented, nextlevel ultra-telephoto zoom lens with added versatility that starts at 50mm and delivers an 8x zoom ratio. With its wide 50mm starting focal length, full-body shots of subjects like wildlife can be captured in the surrounding environment. The generous and effective use of special lens elements, including XLD (eXtra Low Dispersion), LD (Low Dispersion) and Hybrid Aspherical lens elements, effectively delivers uncompromising high image quality throughout the entire 50-400mm zoom range. Along with its superb performance, the lens is just 183.4mm long and weighs only 1,155g. Offering about the same light weight and compact size as a conventional 100-400mm zoom, it’s easy to pack and comfortable to carry all day. Clearly, the TAMRON 50-400mm F4.5-6.3 is a brand-new kind of ultra-telephoto zoom lens that combines a 50mm standard focal length, outstanding image quality and highly nimble mobility—plus the sheer power of a 400mm telephoto! This one lens captures a lively world with all the clarity you desire and can transport you to exhilarating new photographic experiences.

Fast and precise AF, plus VC for stable handheld shooting
The 50-400mm F4.5-6.3 utilizes the renowned VXD1 linear motor focus mechanism. This advanced AF mechanism combines class-leading speed and precision, enabling fast and accurate focusing from MOD (Minimum Object Distance) through to infinity. The lens is equipped with TAMRON's proprietary VC2 mechanism, and effectively controls camera shake that can occur when shooting at telephoto focal lengths. It also helps reduce fuzzy pictures when shooting handheld in low-light conditions which typically require slower shutter speeds.

Half-macro photography with 1:2 magnification ratio at the 50mm end
The 50-400mm F4.5-6.3 is capable of extremely high performance when shooting close-ups, particularly for an ultra-telephoto zoom lens. Users can enjoy half-macro shooting with an MOD of 0.25m and a maximum magnification ratio of 1:2 at the 50mm zoom setting. Moreover, at the 400mm telephoto end, the MOD is 1.5m, thereby providing a maximum magnification ratio of 1:4 for amazing, dynamic shots. The unprecedented level of freedom in shooting reveals the charm of subjects more than ever, plus flexible shooting options previously unseen in ultra-telephoto zooms.

Zoom Lock mechanism
The ZL mechanism prevents unwanted extension of the tube during transport. The lock, which is activated by a switch, protects the lens from damage and at the same time guarantees that it is quickly ready for use.

TAMRON Lens Utility
The new software „TAMRON Lens Utility“, has been specially developed by Tamron to configure its own compatible lenses. TAMRON Lens Utility can be operated using computer by connecting the lens from its Connector Port via the optional TAMRON Connection Cable. Users can customize the functions and update the firmware through the lens. The personal customization gives flexible shooting options to match the shooting situation such as still photography or videography. With the help of the personal configuration, the lens can be optimally adapted to the respective shooting situation, for example photo or video.
