Excellent clarity at all focal lengths. Includes 2 aspheric lens elements to minimize spherical aberrations, coma aberrations, and lens flare. Also includes a circular aperture for natural off-subject defocusing. During AF operation, the manual focus ring does not rotate, which enhances the operability of the lens. SAL75300 75-300mm F4.5-5.6 • Lens groups/elements: 10/13 • Minimum focus: 59" (1.5 m) • Filter diameter: 55 mm • Size: (diameter x length): 2-13/16 x 4-13/16" (71 x 122 mm) • Weight: 1 lb 0.2 oz (460 g) Compact and lightweight zoom lens that ranges between medium telephoto to telephoto focal lengths. Ideal for portraits and for filling the frame with a subject that's situated at a distance. Provides the dual advantages of high optical performance and compact size because of an optical system based on the double telephoto zoom lenses. Also features a circular aperture for beautiful defocusing, and a minimum focusing distance of 1.5 m. 10 SAL16F28 (16mm F2.8 Fisheye) SAL16F28 SAL20F28 16mm F2.8 Fisheye • Lens groups/elements: 8/11 (including 1 filter) • Minimum focus: 7-7/8" (0.2 m) • Filters: 4 types (built-in) • Size: (diameter x length): 2-15/16 x 2-5/8" (75 x 66.5 mm) • Weight: 14.1 oz (400 g) Allows you to capture dynamic images with all the distinctive traits of a fisheye lens: curvilinear distortion, exaggerated perspective, and an extremely deep depth of field. The diagonal angle of view is 180° in 35 mm format (110° in APS-C format). Clear images can be obtained from 20 cm to infinity, even with the aperture wide open. The lens includes 4 internal filters to select from. • Filters: normal; O56 monochrome contrast filter; B12 red reduction filter; A12 blue reduction filter. 20mm F2.8 • Lens groups/elements: 9/10 • Minimum focus: 9-7/8" (0.25 m) • Filter diameter: 72 mm • Size: (diameter x length): 3-1/16 x 2-1/8" (78 x 53.5 mm) • Weight: 10.1 oz (285 g) A wide-angle lens that demonstrates an extremely high degree of distortion compensation, which allows you to capture high-quality images with exaggerated perspective and very deep depth of field. Images are crisp from corner to corner as a result of lens coatings and the reduction of internal light reflection. Various aberrations are compensated for at focusing distances from 25 cm to infinity. The rear focusing mechanism enables quick focusing.
