Seize the moment in its true colors
Travel light, Stay focused
With the culmination of our years of expertise in telephoto zoom lens development, the versatile 70-210mm F/4 Di VC USD (Model A034) provides superb optical performance throughout the entire zoom range. Applying three LD (Low Dispersion) lens elements enables the Model A034 to correct chromatic aberrations effectively while shooting for clear, crisp images to the edges of the frame. Also, by achieving a maximum magnification ratio of 1:3.1, the highest in its class,* you will enjoy ultra-soft “bokeh” when shooting up close. Additionally, the Model A034 supports photo shooting with various features such as an internal zoom mechanism that provides solid mechanical construction and stable, reliable operation, and a Dual MPU (Micro-Processing Unit) design, which enables high-speed and high-accuracy AF performance as well as powerful VC (Vibration Compensation) image stabilization for flexible and versatile use in various situations. For dependable outdoor use, the new telephoto zoom is equipped with Fluorine Coating and Moisture-Resistant Construction. Lightweight and compact, this telephoto zoom is ideal for travel. Now you can go lightweight while greatly expanding your shooting possibilities.

With a category-leading magnification ratio of x0.32, this telephoto zoom lens achieves a MOD of just 0.95m. Get closer to your subjects and feel the freedom of shooting.
An internal zoom provides stability by minimizing changes to the center of gravity while shooting. Combined with Moisture-Resistant Construction, the internal zoom creates an easier all-around shooting experience. Also, since the total length of the barrel never changes while zooming, you can easily shoot through obstructions such as wire fencing.
Reliable autofocus tracking and vibration compensation are essential in a telephoto zoom lens. Tamron’s Dual MPU (Micro-Processing Unit) system on this lens strikes a balance between both. It includes two dedicated MPUs: one for lens system control including AF, and the other for vibration compensation processing. Each MPU is equipped with a DSP (Digital Signal Processing) block with high signal processing for exceptional AF performance and vibration compensation effects.
Capture the moment with lightning-quick AF
Tamron’s evolved AF is lightning quick to help you capture each precious moment. The USD (Ultrasonic Silent Drive) ring-type motor in the drive unit ensures fast, highly accurate focusing, allowing you to shoot with confidence.
Keep it stable with four-stop VC (Vibration Compensation)
Tamron’s proprietary VC system features four-stop** performance to control the vibrations that can easily occur in low-light conditions. Now you can enjoy sharper images and shake-free handheld shooting—even when shooting in the evening or indoors.
** CIPA Standard Compliant. For Canon: EOS-5D MKIII is used; for Nikon: D810 is used.
An optional tripod mount compatible with Arca-Swiss style quick release plates is available for the A034. Arca-Swiss style mounts can be easily attached and detached and are renowned for their excellent stability. In keeping with the lightweight nature of this zoom lens, the tripod mount is made of a light yet robust magnesium alloy to support you in a wide range of photographic conditions—like shooting at a slow shutter speed. Using a tripod makes the lens more stable, as opposed to attaching a tripod to a camera body to prevent blurred images. And since this tripod mount allows the camera body to rotate freely without moving its axis, adjusting composition is easy. Broaden your shooting style with a tripod mount that lets you shoot what you want, how you want, even at slow shutter speeds.

Optical Construction (20 elements in 14 groups)
MTF (Modulation Transfer Function) curves describe to what extent the tested lens can faithfully reproduce contrast of the subject in images it captures.
The closer the 10 lp/mm (line pairs per millimeter) curve (the thick line for low frequency) in an MTF chart to "1" of the vertical axis (the higher up), the higher the contrast reproduction performance of the tested lens will be. The closer the 30 lp/mm curve (the thin line for high frequency) to "1" (the higher up), the higher the resolving power and thus the subjective sharpness of the lens will be.
Lens performance differs depending upon directions. Solid lines show performance in the sagittal (radial) direction while dotted lines indicate performance in the meridional (circumferential) direction. When sharp lenses capable of delivering uniform optical performance over the entire image field are tested, MTF charts show curves plotted in good balance.
Performance characteristics of photographic lenses cannot be expressed with only MTF charts. There are other factors that are expressed in different methods, such as taste of softness and degrees of compensation of various aberrations. But you can use MTF charts as a scale to measure lens performance.
