Tamron 100-400mm f/4.5-6.3 Di VC USD Lens with 1-Year Warranty

The Tamron 100-400mm f/4.5-6.3 Di VC USD (Model A035) is an agile, high-performance ultra-telephoto zoom lens built for full-frame Canon EF and Nikon F mount DSLR systems. Engineered to break the stereotype that long telephoto lenses must be heavy and cumbersome, this lens utilizes a magnesium alloy lens barrel to deliver the lightest weight in its class. Featuring advanced dual microprocessors for speedy autofocusing and highly effective optical stabilization, it is a premier tool for capturing far-off sports action, aircraft, and elusive wildlife without requiring a tripod.

Tamron 100-400mm Key Features & Benefits

• Ultralight Magnesium Construction: Built with magnesium alloy components in key sections of the lens barrel, making it exceptionally lightweight at just 39.3 oz (1,115g) and vastly improving handheld portability during long field sessions.

• Dual MPU Dedicated Control System: Employs two separate micro-processing units—one dedicated exclusively to processing lens stabilization data and the other to tracking high-speed autofocus—for unmatched real-time responsiveness.

• Vibration Compensation (VC): Tamron’s built-in optical stabilization counteracts handheld camera shake by up to 4 stops (CIPA-rated), guaranteeing sharp, blur-free images when tracking fast-moving subjects at the maximum 400mm focal length.

• Ultrasonic Silent Drive (USD): The ring-type ultrasonic AF motor enables lightning-fast, whisper-silent focus locking. It features full-time manual focus overrides, allowing you to instantly tweak focus points manually without flicking a switch.

• Premium Low-Dispersion Optics: Features 3 LD (Low Dispersion) glass elements engineered precisely into the optical pathway to eliminate chromatic aberrations and color fringing, maintaining high contrast and corner-to-corner clarity.

• Outdoor Moisture Resistance: Outfitted with protective weather seals at all crucial entry points to prevent dust and water intrusion, paired with an advanced Fluorine coating on the front element that wipes clean easily from smudges, grease, and rain.

Tamron 100-400mm Suitability

• Wildlife & Bird Photographers: Offers an expansive telephoto reach of up to 400mm (expanding up to a 640mm equivalent when mounted on an APS-C crop sensor body), which is perfect for filling the frame with distant animals.

• Outdoor Sports & Action Creators: Light enough to carry up and down sidelines or tracks all day, while the high-speed USD autofocus smoothly tracks running athletes or speeding vehicles.

• Aviation & Travel Photographers: Compact enough to pack easily into standard camera backpacks, making it an excellent companion for capturing sharp silhouettes of aircraft or distant mountain peaks against the horizon.
