Tamron – Canon 100-400mm F/4.5-6.3 Di VC USD Lens (104A035E)

Heavyweight performance in a lightweight lens – Mobility meets precision with the Model A035 ultra-telephoto lens

The Tamron 100-400mm F /4.5-6.3 Di VC USD (Model A035) is a highly portable, ultra-telephoto zoom lens with AF precision for shooting instantaneous movement with the utmost clarity. With this effectively positioned, extraordinary glass LD (Low Dispersion) lens, aberrations typical with many telephoto lenses are a thing of the past.

Tamron’s proprietary eBAND (Extended Bandwidth & Angular-Dependency) Coating suppresses reflections, yielding vivid images of amazing clarity. And thanks to a lens barrel made primarily of magnesium, the 100-400mm boasts the lightest weight in its class*, making it ideal for handheld shooting over long periods of time. With a MOD (Minimum Object Distance) of 1.5m and a maximum image magnification ratio of 1:3.6, the 100-400mm lets you soften the foreground or background to dramatically emphasize your subject at close range. Moisture-Resistant Construction and a fluorine-coated front element provide additional protection when shooting outdoors.

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

Tamron has fine-tuned their 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.
