Superb corner-to-corner image quality from an ultra-wide-angle zoom
Tamron aims for the highest standards with the SP (Super Performance) lens series and the 15-30mm F/2.8 full-frame ultra-wide-angle zoom is a worthy addition. This high-performance zoom lens equals the performance of fixed focal length lenses from 15mm to 30mm, an unprecedented achievement made possible by the development of its unique XGM (eXpanded Glass Molded Aspherical) lens element that effectively controls aberrations and enhances sharpness. The 15-30mm combines a wide range of coverage, a fast F/2.8 aperture, and image stabilization, further proof of Tamron's commitment to innovation and excellence.
Superb image quality and performance
With an optical construction of 18 elements in 13 groups, inclusive of XGM (eXpanded Glass Molded Aspherical) element placed at the front group and several LD (Low Dispersion) glass elements in the system, aberrations such as geometrical distortion and lateral color are efficiently compensated for enabling the zoom lens to deliver outstanding image quality throughout the entire range from corner to corner.
Prominent competence of VC when shooting night scenes and under low light conditions
Recognizing the needs for image stabilization capability on a wideangle lens voiced by a number of photographers, especially for a full-frame, fast F/2.8 ultra-wide-angle zoom lens category, VC is tuned for providing discernible competence throughout the entire zoom range. The feature enhances image depicting capabilities for shooting night scenes and under low light conditions.
Benefit of the eBAND and the improved BBAR coatings
Tamron's acclaimed BBAR (Broad-Band Anti-Reflection) coating is further refined to render uniformity in transmissivity across the critical bandwidths. Coupled with the eBAND coating, ghosting and flare typically observed on ultra-wideangle lenses are efficiently eliminated, resulting in crisper and crystal-clear images.
Fluorine Coating on the front element, Tamron's first
Due to the large diameter and the prominent convex profile of the front element, it is not practical to deploy a protective filter. For the first time, a fluorine coating is applied to the front element, which repels water or any type of dirt, while making it easier to remove such smudge when contaminated.
Fascinating background "bokeh" with the fast maximum aperture of F/2.8
Natural and smooth blur on the subject background enhances depictive capabilities of wide-angle photography when a subject is located in the close distance. The 9-blade diaphragm construction retains a near-circular aperture opening even when stopped down by two steps from its full open position and delivers ideal bokeh effects.
Speed of autofocus and control accuracy are further improved. USD(4) (Ultrasonic Silent Drive) delivers tack-sharp images due to the high torque and fast response speed with least amount of lag time, yet with extremely low acoustic noise. Equipped with a full-time manual focus mechanism, fine focus adjustments are enabled without exiting from the AF mode.
Comes with "SILKYPIX Developer Studio for Tamron", RAW image processing software customized for Tamron SP lenses
The SILKYPIX Developer Studio software provides an added feature to generate high-quality images from RAW data, while performing adjustments to reflect a personal style and a taste of the photographer. These include white balance, color, sharpness, and the tonal curves recorded by digital cameras.
The SILKYPIX Developer Studio for Tamron provides a range of functions, in addition to the basic adjustment capabilities, such as correcting aberrations (lateral color, distortion, relative illumination fall-off) referring to the optical design data. Optimal use with Tamron's SP series lenses - renowned for their high-depiction capabilities - delivers images that meet photographers' most exacting demands.
