Tamron SP AF10-24mm F/3.5-4.5 Ultra Wide-angle Zoom Lens
Tamron Co. Ltd issued a press release last September to announce a new 10-24mm wide-angle zoom lens. Now available at retailers, the SP AF10-24mm F/3.5-4.5 Di II LD Aspherical (IF) lens features a 2.4X zoom ratio in a in a user-friendly lightweight, compact design. Tamron’s “SP Di II class” lenses provide high optical quality in resolution, contrast, and flatness of image field.
The new AF10-24mm lens uses a high-precision, large-aperture glass-molded aspherical lens element and three hybrid aspherical elements to minimize spherical aberration, coma, and distortion. In addition, a pair of LD (Low Dispersion) glass elements compensates for on-axis and lateral chromatic aberrations, delivering high optical quality.
Because a close-focusing capability is essential in wide-angle photography, Tamron engineered a 0.24m (9.4”) minimum focus distance across the zoom range. This capability gives the user freedom to create images with an exaggerated perspective at the 10mm ultra wide-angle end and shoot with a maximum magnification ratio of 1:5 at the 24mm semi-wide-angle setting.
A glare-reducing, flower-shaped lens hood is included as a standard accessory. The special hood provides optimum shading of light rays that enter from the rectangular frame outside the image field.
The new AF10-24mm lens also features a refined exterior design that eliminates unevenness in the lens body and enhances its uniformity and smoothness, matching the designs of current digital SLRs.
