¶ Heavyweight performance in a lightweight lens
¶ Mobility meets precision with the Model A035 ultra-telephoto lens
¶ Get into The Action
Not all telephoto DSLR lenses are built alike, and many 100-400mm lenses are bulky, heavy, and hard to adjust, making them less-than-ideal for capturing action on the racetrack, in nature, or anywhere else you shoot with a telephoto lens.
But with the Tamron 100-400mm F/4.5-6.3 Di VC USD lens (Model A035), all of that is about to change. This ultra-telephoto zoom lens provides a focal length of up to 400mm with incredible precision, while remaining lightweight and easy to carry and shoot with. Match it with Tamron’s exclusive 1.4X or 2X teleconverters for even greater tele reach.
While 100-400mm lenses from other manufacturers can weigh up to 4lbs or more, the A035 is the lightest zoom lens in the ultra-telephoto category, with a weight of just 2.45 lbs. Thanks to a compact design that incorporates advanced composites and lightweight magnesium, the A035 is maneuverable enough to take anywhere you need it to go.
Not only that, but the Tamron Model A035 lens offers unparalleled image quality, thanks to Tamron’s eBAND (Extended Bandwidth & Angular-Dependency) coating, which eliminates internal reflections and provides you with improved clarity. With moisture-resistant construction and a fluorine coating, it’s built to last, even when shooting outdoors.
Other advanced features include a built-in DSP (digital signal processor) for unparalleled autofocus responses, and a USD (ultrasonic silent drive) for fast, precise focusing. An enhanced vibration compensation (VC) system helps eliminate shakiness and vibrations to ensure clear images, even in low-light conditions.
The Tamron A035 lens is available to mount on both Nikon and Canon DSLR cameras as well as mirrorless cameras using the manufacturer’s adapter and is available with an optional tripod mount provides you with more flexibility as you shoot.
¶ Excellent AF performance meets enhanced VC
Precise AF tracking and VC (Vibration Compensation) are essential for ultra-telephoto lens performance. Thatʼs where Tamronʼs Dual MPU high-speed control system comes in. It features an MPU (micro-processing unit) with a built-in DSP (Digital Signal Processor) for superior signal processing, plus a separate MPU dedicated exclusively to vibration compensation. With enhanced AF response speed and VC, you can accurately shoot fast-moving subjects with stability and ease—even in low-light.
¶ Precise, responsive AF performance
A built-in DSP (Digital Signal Processor) on the MPU delivers highspeed processing of digital signals, while ensuring excellent AF responsiveness. This improvement allows you to track subjects moving at high speeds, even more accurately. The AF drive system also uses a USD (Ultrasonic Silent Drive) motor for outstanding performance and fast, precise focusing.
¶ Keep it steady with enhanced VC
Weʼve fine-tuned our original VC (Vibration Compensation) system with an enhanced control algorithm and an independent MPU dedicated to VC. Together, they meet a CIPA image stabilization performance level of 4 stops. While most ultra-telephoto lenses are prone to camera shake, the Model A035 delivers excellent stability for reliable, stress-free handheld shooting.
