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
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.
Better bokeh, Greater stability
With a minimum object distance of 1.5m (59 in) and a maximum image magnification of 1:3.6, the Model A035 can zoom in on a subject smoothly, resulting in close-up shooting with a soft, blurred effect.
High-speed Dual MPU (Micro-Processing Unit) control system delivers quick and highly responsive autofocus performance plus outstanding VC image stabilization
The Dual MPU system includes an MPU dedicated to vibration compensation processing, enhancing the computational capacity of the entire system. An MPU with built-in DSP (Digital Signal Processor) provides high-speed digital signal processing and achieves outstanding autofocus performance and vibration compensation, both indispensable for ultra-telephoto photography.
Superb image quality in an ultra-telephoto zoom lens
The Model A035 includes three LD (Low Dispersion) lens elements for optimal optical design and aberration correction. Lighter weight, increased light transmission and crisp images with excellent contrast are achieved by reducing the number of lens elements while ensuring an appropriate balance with aberration correction. The A035 has minimum object distance (MOD) of 1.5 m (59 in) and a maximum magnification ratio of 1:3.6 for close-up work.
Exclusive eBAND Coating reduces flare and ghosting
The new A035 features Tamron’s eBAND (Extended Bandwidth & Angular-Dependency) Coating, which has an extremely low refractive index and fine multiple-layer coating technology, to achieve outstanding antireflection performance. BBAR (Broad-Band Anti-Reflection) Coating, with excellent antireflection characteristics, increases light transmission. These coating technologies greatly reduce the ghosting and flare that can occur when subjects are backlit.
Lightest weight, 1,115 g (39.3 oz) lens in the ultra-telephoto zoom lens class, and only 196.5 mm (7.7 in) long
Magnesium alloy is used in key areas of the lens barrel to improve weight reduction, strength and portability. Total length of 196.5 mm (Nikon mount) means a compact size for an ultra-telephoto zoom lens covering up to 400 mm, and the A035 can therefore be easily carried in a standard camera bag. Combined with excellent vibration compensation functions, the compact size enables successful handheld ultra-telephoto photography.
Optional accessory tripod mount is Arca-Swiss compatible
An Arca-Swiss style tripod mount is available as an optional accessory. Designed exclusively for Model A035, it provides quick and secure attachment to a tripod and greater stability. An easy-to-hold grip shape includes an expanded mounting plane, and the use of magnesium helps achieve lighter weight, thereby further facilitating handheld photography.
Compatible with tele converters and TAP-in Console
Model A035 is compatible with tele converters designed exclusively for Tamron lenses to achieve 1.4X and 2X the original focal length*. It’s also compatible with Tamron’s TAP-in Console (Model TAP-01), an optional accessory enabling users to update lens firmware and customize the lens settings, including adjustments of focusing positions for autofocusing and the operation modes for the lens’s Vibration Compensation system.
*Use of the 1.4× tele converter results in light reduction of 1 F stop; use of the 2× tele converter results in the loss of 2 F stops.
- *1 Autofocus functions normally on any camera that offers F/8 autofocusing (see your camera’s instruction manual for your camera’s ability).
- *2 Subjects with low contrast and/or luminosity values can sometimes result in out-of-focus images.
Moisture-Resistant construction and fluorine coating for enhanced weather protection
The surface of the front element is coated with a protective fluorine compound that has excellent water- and oil-repellant qualities. The front surface is easier to wipe clean and is less vulnerable to the damaging effects of dirt, dust, moisture or oily fingerprints, allowing for much easier maintenance. Also, with active use of the A035 for outdoor photography likely, sealant is used in each of the movable and joining areas of the lens barrel to resist the intrusion of moisture.
External design places importance on functionality and ease of use
While inheriting the design that makes use of many organic curves and the delicately polished form down to fine details that characterize the SP lens series, the new Model A035 comes with a highly sophisticated design that also places a lot of importance on the lens’s functionality and ease of use, featuring an overall form that faithfully encompasses the internal structures within, a slim Luminous Gold brand ring and the switch shape design.
