Covers 50mm standard focal length up to 400mm at the ultra-telephoto range, 50-400mm F/4.5-6.3 Di III VC VXD (Model A067)
One of the greatest features of the 50-400mm F4.5-6.3 is its dramatically broad range of focal lengths which covers 50mm to 400mm and delivers an 8x zoom ratio. With a focal length of 50mm at the wide end, you can create images that capture the subject and also make use of the background as well as subjects that may continuously move closer and further away, such as when whale watching, shooting sports at the sidelines, and photographing animals in habitats. Users can enjoy shooting a vast variety of subjects from landscapes and wild birds to animals, sports and small groups. Despite its wide range and capabilities, the compact and lightweight zoom measures just 183.4mm (7.2 in) and weighs 1,155g (40.7 oz). This makes the lens easy to handle, and also makes it useful in situations like air travel when you want to reduce the bulk you are carrying.

Outstanding image quality throughout the entire 50-400mm zoom range
The 50-400mm F4.5-6.3 was developed in pursuit of high image quality throughout the entire zoom range. The optical construction features 24 elements in 18 groups. The generous and effective use of special lens elements, including XLD (eXtra Low Dispersion), LD (Low Dispersion) and Hybrid Aspherical lens elements thoroughly controls aberrations including axial chromatic aberrations. The 50-400mm F4.5-6.3 also features BBAR-G2 (Broad-Band Anti-Reflection Generation 2) Coating that minimizes ghosting and flare and expresses the minute details of subjects even under backlit conditions. Enjoy clear and sharp resolution to the edges of the frame, plus the soft, beautiful bokeh effects of the type that only an ultra-telephoto can create.

High-speed, high-precision AF means you’ll never miss another photo opportunity
The 50-400mm F4.5-6.3 utilizes the renowned VXD linear motor focus mechanism. This advanced AF mechanism combines class-leading speed and precision, enabling fast and accurate focusing from MOD through to infinity. What’s more, excellent focus tracking performance of moving objects makes it possible to capture sharp images even when shooting wild birds and fast sports action.

TAMRON's proprietary VC takes the shakes out of handheld shooting
The lens is equipped with TAMRON's proprietary VC 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 or at slower shutter speeds. Furthermore, using AI technologies, the lens chooses the appropriate compensation characteristics for videography at focal lengths of 100mm or less.

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 (9.8 in) and a maximum magnification ratio of 1:2 at the 50mm zoom setting. Moreover, at the 400mm telephoto end the MOD is 1.5m (59.1 in), providing a maximum magnification ratio of 1:4 for dynamic shots. The unprecedented level of freedom in shooting reveals the charm of subjects more than ever, and flexible shooting options previously unseen in ultra-telephoto zooms.

"Focus Limiter" function that limits the AF focus search range has been added to the TAMRON Lens Utility
The dedicated TAMRON Lens Utility software developed in-house by TAMRON is compatible with the 50-400mm F4.5-6.3. Simply connect the Connector Port on the lens to a computer via the optional TAMRON Connection Cable*. Users can customize the functions and easily update the firmware through the lens. Additionally, with the 50-400mm F4.5-6.3 you can select the “Focus Limiter” function that allows you to limit the focus search range of the AF. This function shortens the time taken to refocus when a subject slips out of focus and prevents focusing on obstacles in front of a subject. The function can be instantly toggled using the Focus Set Button, ensuring that you never miss an unexpected photo opportunity. The TAMRON Lens Utility can be used to customize functions based on various shooting styles for both still photography and video, thereby providing a more fulfilling shooting experience.

Built with Mirrorless in Mind

• Fast Hybrid AF
• Eye AF
• Direct Manual Focus (DMF)
• In-camera lens correction (shading, chromatic aberration, distortion)

Circular aperture to produce a smooth-edged bokeh
A 9-blade diaphragm is configured to retain a smooth, circular-shaped aperture opening even when stopped down by two stops from the wide-open aperture. This produces a smooth-edged bokeh in background highlights.

BBAR-G2 Coating delivers stunning clarity and contrast
TAMRON has long been an innovator of coating technologies that prevent ghosting and flare. Second-generation BBAR-G2 Coating is a groundbreaking advancement that provides vastly improved performance compared to the original BBAR (Broad-Band Anti-Reflection) Coating. The coating corrects for ghosting and flare to an unprecedented extent and renders fine subject detail with true clarity and stunning contrast even under backlit conditions.

Zoom Lock switch
The 50-400mm F4.5-6.3 has a switch that can lock the zoom ring at the 50mm focal length if desired. This prevents the unwanted extension of the lens barrel due to the weight of the lens during transportation.

Moisture-Resistant Construction protects your lens
For greater protection when shooting outdoors, leak-resistant seals throughout the lens barrel help protect your equipment. Also, the Connector Port is the water-proofed USB Type-C variety.

Fluorine Coating for protection and safe cleaning
The front surface of the lens element is coated with a protective fluorine compound that is water- and oil-repellant. The lens surface is easier to wipe clean and is less vulnerable to the damaging effects of dirt, dust, moisture, and fingerprints.
