First-ever Ultra Wide-angle10-24mm Focal Length Range
This ultra wide-angle zoom lens for digital SLR cameras, with the first-ever focal length range of 10-24mm—the 35mm equivalent of 16mm ultra wide-angle to 37mm semi-wide-angle—is a perfect tool for creating dramatic landscape, cityscape, and seascape imagery. At the ultra wide-angle setting, you’ll be able to capture vistas beyond what the eye can see. At the semi-wide-angle setting, you’ll capture scenes with angles of view almost as spectacular. Building on Tamron’s existing ultra wide-angle zoom lens (11-18mm F/4.5-5.6), this versatile lens expands the focal length range and enhances the maximum aperture—in a lightweight, compact form.

Large-aperture Glass-molded Aspherical Lens Elements Deliver High-Quality Imagery
The optical system within this zoom lens uses three large-aperture glass-molded aspherical lenses, as well as three hybrid aspherical lenses, which minimize spherical aberrations, coma, and distortion. This lens has earned its place within Tamron’s SP (Super Performance) series.

Minimum Focusing Distance of 0.24m Across Zoom Range
The close focusing capability of this lens lets you capture images with an exaggerated perspective at the 10mm ultra wide-angle end or shoot with a maximum magnification ratio of 1:5 at the 24mm semi-wide-angle setting. You will enjoy the freedom of creating close-ups at the minimum focusing distance of 0.24m throughout the zoom range.

Lens Construction <9 Elements 12 Groups>

Since the size of full-size format is different from the APS-C size imager, scopes captured are different even when focal lengths are the same (i.e., angles of view differ).
The SP AF10-24mm Di II is designed to have shorter focal lengths to achieve optimum angles of view in its wide-angle side.

Designed to capture the optimum scope when used with a APS-C digital camera


		Attempts to design shorter focal lengths inevitably result in a larger lens diameter. Tamron has solved this problem by designing the size of the lens' image circle to match that of APS-C size imagers. In the compact design, it is almost comparable to a lens offering the same angles of view in full-size format.
		* When pictures are taken with a Di-II lens on a full-size format, image corners become dark (ie., vignetting becomes noticeable).
