A world of wonder awaits you
Ultra-optimized optics create yet another incredible image
The SP 15-30mm F/2.8 Di VC USD G2 (Model A041) is a high-speed ultra-wide-angle zoom lens with ultimate image quality that lets you capture all you see.
By utilizing specialty glass materials and aspherical lens elements in the new Model A041, Tamron’s engineers have further minimized the distortion and lateral chromatic aberration that can be an issue with wide-angle shooting. The lens also has triple lens coatings consisting of the newly developed AX (Anti-reflection eXpand) Coating, plus eBAND (Extended Bandwidth & Angular-Dependency) and BBAR (Broad-Band Anti-Reflection) Coatings, which all combine to provide sharp and clear images even in peripheral areas. The Model A041 lens features high precision AF technology and a powerful VC (Vibration Compensation) mechanism. A rear filter holder (for Canon EF-mount only) comes as a standard feature, making the use of filters much easier. As well as Moisture-Resistant Construction, wide-ranging features such as Fluorine Coating newly developed enhancing durability, make it possible to shoot under any type of shooting circumstances.
The SP 15-30mm F/2.8 Di VC USD (Model A012) is a high-quality F/2.8 ultra-wide-angle zoom lens for use with full-frame DSLR cameras that has been lauded by photography enthusiasts throughout the world. To further enhance this legacy of high-quality optics, new functions have been added to create the next generation model, the SP 15-30mm F/2.8 Di VC USD G2 (Model A041) . Incorporating an XGM (eXpanded Glass Molded Aspherical) lens element as well as multiple LD (Low Dispersion) lens elements provides high definition images throughout the entire zoom range.
A new revolutionary AX (Anti-reflection eXpand) Coating is accomplished through Tamron's proprietary deposition technology that addresses the difficulty of applying uniformed coating using existing technology. Now the coating can be applied uniformly edge to edge, even if the convex surface has a strong curvature. As a result, the reflectance and color rendition at the peripheral part of the element is the same as the center. The new AX Coating, which is especially effective for wide-angle lenses that tend to let in harmful light from peripheral areas, effectively minimizes ghosting and provides outstanding uniform image clarity.
In order to engage the full optical performance of the lens, it is essential to control the slightest blur and precise focusing. In this respect, the lens applies a Dual MPU (Micro-Processing Unit), which includes two dedicated MPUs, one for lens system control including AF, and the other for vibration compensation processing. AF speed and precision have been enhanced and image stabilization has been vastly improved, reaching 4.5 stops* according to CIPA standards. Even for handheld shooting, the blur that often arises in low-light conditions is effectively controlled.
* CIPA Standard Compliant. For Canon: EOS-5D MKIII is used. For Nikon: D810 is used.
High precision AF lets you take steady shots
The AF drive uses proprietary Tamron technology, USD (Ultrasonic Silent Drive) providing high torque, response, and silent operation. Manual focus adjustments can be made on the fly with the lens’s Full-time Manual Focus Override system.
The VC mechanism provides powerful support for handheld shooting
The Model A041 has an improved VC (Vibration Compensation) mechanism with vastly better image stabilization performance from the previous Model A012, reaching 4.5 stops according to CIPA standards. This enables sharper images over a wide range of photographic situations, including indoor and outdoor shots as well as landscape photography at stopped-down aperture settings.
The durability of the front element coating is greatly improved with the development of new Fluorine Coating. With the new fluorine compound that has excellent water- and oil-repellent properties, the lens surface is much easier to wipe clean and less vulnerable to damaging effects of dirt, dust, moisture, and fingerprints, and enabling your important lenses to be continually protected on a long-time basis.
A filter holder that allows you to attach gelatin filters to the rear side of the lens is included as a standard feature (for Canon EF-mount only). You can now shoot with filters much more easily, traditionally rather difficult when shooting with ultra-wide-angle lenses with large front lens elements.
The SP 15-30mm F/2.8 Di VC USD G2 (Model A041) integrates engineering with human touch design, aiming at intuitive operability, while still emphasizing minute details and texture. The lens is more user-friendly because of innovations including a new switch box design, an improved distant-scale window, and the precision and stability of the metallic mount.
Now three of high-speed zoom lens with VC, SP 15-30mm F/2.8 Di VC USD G2 (Model A041), SP 24-70mm F/2.8 Di VC USD G2 (Model A032) and SP 70-200mm F/2.8 Di VC USD G2 (Model A025), are reborn as Generation 2, providing you with the feeling of luxury and operation unique to the human touch design.

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.
