Tamron upgrades its legendary ultra-wide-angle zoom lens
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 have 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 Moulded Aspherical) lens element as well as multiple LD (Low Dispersion) lens elements provides high definition images throughout the entire zoom range.
The newly developed AX Coating enables sharp images
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 colour rendition at the peripheral part of the element is the same as the centre. The new AX Coating, which is especially effective for wide-angle lenses that tend to let in harmful light from peripheral areas, effectively minimises ghosting and provides outstanding uniform image clarity.
A great AF performance and image stabilisation bring out the lens’s optical performance
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 stabilisation 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.
New Fluorine Coating for improved durability
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.
The rear filter holder enables greater creative flexibility
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.
