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 in-the-moment action clearly and easily. 3 ld (low dispersion) glass elements are used and effectively positioned to take away aberrations that are known to occur with telephoto lens. and tamronʼs proprietary eband (extended bandwidth & angular-dependency) coating prevents reflections, giving you clearer, more vivid images. with a lens barrel made primarily of magnesium at selected area, the model a035 is the lightest zoom in the ultra-telephoto category, making it ideal for handheld shooting over long periods of time. plus, moisture-resistant construction and a fluorine-coating on the front element provide additional protection when shooting outdoors.
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.
a built-in dsp (digital signal processor) on the mpu delivers high speed 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.
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.
