Tamron 50-300mm F/4.5-6.3 Di III VC VXD (A069) (Sony E)

The Tamron 50‑300mm F/4.5‑6.3 Di III VC VXD (Model A069) is a versatile telephoto zoom lens designed for Sony E‑mount full‑frame mirrorless cameras. This lens introduces an unconventional yet highly functional zoom range that starts at 50mm and extends to 300mm, offering a useful balance between standard and long‑reach telephoto performance. Its compact size and class‑leading weight make it an excellent choice for photographers who want broad focal coverage without the bulk.

Key Features

Wide Telephoto Zoom Range
With a focal length range from 50mm to 300mm, this lens seamlessly transitions from general shooting to long‑distance subjects. It’s ideal for portraits, sports, wildlife, travel, and outdoor photography. On APS‑C cameras, this translates to an effective range of approximately 75–450mm.

Compact and Lightweight Design
Despite its impressive 6× zoom ratio, the lens remains compact at approximately 150mm in length and weighs just 665g, making it one of the lightest full‑frame telephoto zoom lenses with vibration compensation available.

VXD Linear Autofocus Drive
Autofocus is powered by Tamron’s VXD (Voice‑coil eXtreme‑torque Drive) linear motor system, delivering fast, precise, and quiet focusing performance. This makes it suitable for both still photography and video work — especially when capturing fast‑moving subjects.

VC (Vibration Compensation) Image Stabilization
Built‑in Vibration Compensation (VC) helps to reduce camera shake, improving sharpness at longer focal lengths and when shooting handheld — particularly useful for wildlife or outdoor sports photography.

Half‑Macro Capability at Wide End
At the wide 50mm end, the lens offers a maximum magnification ratio of 1:2, allowing half‑life‑size close‑up shooting without a dedicated macro lens. Even at 300mm, it achieves a significant magnification of 1:3.1, providing creative framing and detail when needed.

Build Quality and Handling

Optical Excellence
The lens consists of 19 elements in 14 groups, including special optical glass designed to suppress chromatic aberrations and deliver sharp images across the entire zoom range. BBAR‑G2 (Broad‑Band Anti‑Reflection Generation 2) coating helps reduce flare and ghosting for clearer results in backlit and challenging lighting conditions.

User‑Friendly Design
The exterior features a glossy black surface with improved abrasion resistance and deep grooves on the focus/zoom rings for better grip. Moisture‑resistant construction and a fluorine‑coated front element help protect the lens when shooting outdoors.

Standard 67mm Filter Thread
A 67mm filter mount ensures easy compatibility with commonly used filters like UV, ND, and polarizers — ideal for landscape and outdoor photography.
