All-new optical design achieving the highest-level performance
The optical design has been completely overhauled in comparison with the previous model (A009), and superior performance and resolution is now ensured across the entire zoom range. Outstanding optical performance that is uniform and well-balanced is maintained, not only in the 70mm wideangle range but also in the middle focal ranges and the 200mm telephoto range. Using the A025 in combination with a dedicated tele converter attached makes it possible to fully enjoy ultra-telephoto photography while maintaining excellent optical performance.

Improved depictive quality in the wide-angle focal range
With transverse chromatic aberrations minimized, improvements have been made in the periphery of the image plane on the wide-angle side. Its deliver the sharpness and high resolution in the periphery.
Improved depictive quality in the telephoto focal range
Deploying the LD lens element has minimized axial chromatic aberrations occurring on the telephoto side.

The optical design of the new A025 consists of 23 elements in 17 groups. 1 XLD (eXtra Low Dispersion) and 5 LD (Low Dispersion) lens elements are used. The optimum deployment of both of these elements completely eliminates chromatic aberrations, which tend to become particularly prominent in high-speed telephoto zoom lenses.

The optical design was completely reworked to better accommodate the higher pixel-density digital cameras of the new era. Considering the need to also maintain excellent image quality when using a tele converter, creative ideas have been incorporated to the utmost to consistently ensure high-level performance. As a result, outstanding resolution and contrast reproduction performance is achieved across the entire zoom range.

For the new A025, the designers placed importance on its spectacular background blur effects, a significant factor comprising the depictive quality of a high-speed telephoto lens. Soft, beautifully-tune d background blur effects (bokeh) worthy of a high-speed lens have been achieved as a result. Both the sharp, clear images in the area in focus and the impressively smooth and soft transition to the background accentuate the main subject in an attractive manner in portrait photography, etc

In response to the strong requests of customers using the A009, the predecessor model of the new A025, innovative ideas have been incorporated into the cutting-edge optical design to reduce the Minimum Object Distance (MOD) from 50.7 - to 37.4 for the A025. With a shorter working distance possible, it is easier to determine the composition in a location where there is no more space for the photographer to back up with the camera, enabling close-up photography using a telephoto lens with much greater flexibility. Shooting at and around the minimum focus distance allows for close-up photographic expressions, just like macro photography.

eBAND (Extended Bandwidth & Angular- Dependency) Coating is a nano-structured layer applied to the lens element surface. In addition to regular anti-reflection coatings, eBAND Coating offers higher light transmission and significant improvements in anti-reflection characteristics, particularly against angulated incident rays.

Combined with BBAR (Broad-Band Anti- Reflection) coatings, flare and ghosting are reduced to imperceptible levels.

Improved VC Performance, Function and Usability
The incorporation of two micro computers has reinforced the control performance of Tamron's unique VC system, which now achieves an image stability performance of 5 stops according to the Camera & Imaging Products Association (CIPA) standard for the A025 (when using VC Mode 3). Even for telephoto shooting in low light, which often tends to be affected by camera shake, the photographer can now enjoy handheld shooting with a much greater degree of freedom.

Model A025 now has three types of VC modes, and it is possible to choose the optimum VC mode according to the situation for taking a photograph, such as when wishing to pan the camera.
• VC Mode 1 is the standard mode that strikes an excellent balance between the stability of the viewfinder image and the stabilization effects.
• VC Mode 2 is used exclusively for panning.
• VC Mode 3 prioritizes the stabilization of the captured images and forgoes the stabilization of the viewfinder image

With the optional TAMRON TAP-in Console accessory, the configuration of VC Mode 1 can be customized. Choose the viewfinder view with either standard or viewfinder image priority.

The Model A025 is equipped with an USD (Ultrasonic Silent Drive) ring-type motor that delivers excellent responsiveness and control. AF speed is significantly improved from the current model, and it enables accurate high-speed focus even when capturing moving subjects.

When shooting with AF, the Full-time Manual Focus override allows you to instantly make fine focusing adjustments manually, without having to switch between modes.

Ideal for use in outdoor photography, Model A025 offers Moisture-Proof and Dust-Resistant Construction, thanks to special moisture-proof and dust-resistant sealants used at every joint and seam. The sealant material helps to prevent the intrusion of any dirt, dust or water droplets compared to conventional moisture-resistant construction.

The front surface of the lens element is coated with a protective fluorine compound that is waterand oil-repellant. The lens surface is easier to wipe clean and less vulnerable to the damaging effects of dirt, dust, moisture and fingerprints. 26

The Arca-Swiss style quick release plates can be easily attached and detached and are well known for their stability. A new tripod mount that is compatible with them has now been developed, with particular attention paid to the height of the tripod mount to enhance its integrated feel with the lens barrel in this design, with an increase in rigidity when using a tripod. The use of lightweight magnesium alloy as the material has further eased the burden of carrying the tripod mount for each photographer.

Two exclusive teleconverters, which perfectly match the optics of the new SP 70-200mm G2 (Model A025), offer 1.4x and 2.0x magnification, and provide a maximum zoom range of up to 400mm. These new teleconverters extend the focal length of the master lens, making it possible to take pictures in farther ultra-telephoto ranges. Autofocus and VC features are retained with this Model. Furthermore, they are ideal for use in outdoor photography when matched with any lens that has a Moisture-Resistant Construction. The teleconverters have special seals that are dust-resistant and moisture-proof used at every joint and seam. Compatible with Nikon DSLR cameras.
