The Tamron SP AF10-24mm F/3.5-4.5 Di II LD Aspherical (IF) with Nikon Mount is an advanced ultra wide-angle zoom lens that is versatile and offers even higher performance and specifications than the current Tamron SP AF11-18mm F/4.5-5.6 zoom lens. The lens covers an extended focal length range that is particularly wide for an ultra wide-angle zoom lens, while improving the aperture to F/3.5-4.5 and keeping the filter diameter to 77mm. Its lightweight and compact size makes this new wide-angle zoom very user friendly. The lens was designed for use with digital SLR and thereby employs special optical glass materials for outstanding optical performance such as large-aperture glass-molded aspherical elements and hybrid aspherical elements. Features: Compact Ultra Wide-angle Zoom Lens Covering a Broad Range from 10mm to 24mm - The Tamron zoom covers a focal length range equivalent to 16-37mm* when converted to a 35mm full-size format. Its ultra-wide zoom ratio of more than 2X provides a versatile variety of angles of view, thus improving photographic creativity.Features an Optical Design Optimized for Digital Camera Characteristics Ensures High Optical Performance - 1. Employment of Special Optical Glass Materials Provides High Performance The new zoom lens uses an HID glass element and a pair of LD glass elements to minimize on-axis and lateral chromatic aberrations that are the greatest hindrance to high optical quality. To further achieve outstanding optical quality, the lens uses a high quality, glass-molded aspherical element and three hybrid aspherical elements to thoroughly compensate for spherical and comatic aberrations and distortion. 2. Optical Design Optimizes the Angles of Incidences of Light Rays Reaching the Imager The ultra wide zoom lens uses a new optical system designed to confine the changing angles of incidences of light rays reaching the imager within a certain scope over the entire image field from the center to the periphery, by
