35 mm SLR

Two ELD glass elements in the front lens elements reduce chromatic aberration to a minimum and also ensure sharp, quality images of high contrast. New coating reduces Ghost and Flare The new multi layer lens coating and lens design reduce flare and ghost, which is a common problem with digital cameras and also creates an optimum color balance. It also features a rotatable drop-in filter It also features a drop-in 46mm filter holder in the rear part of the lens barrel, which can be rotated to facilitate the use of filters, including a polarizing filter. Inner Focus Inner focusing retains external dimensions for ease of handling. Accepts both 1.4X and 2X APO EX Tele-Converters. By adding an APO teleconverter (optional extra), you can use this lens as a 700mm F6.3 MF ultra-telephoto lens... Less

Taking picture of small animals and insects can be difficult, because they often run or fly away, or can be dangerous or become aggressive if you approach them. Therefore it is advantageous to have a greater working distance between the camera and such subjects. Longer focal length lens can provide this greater distance, but most long lens do not focus close enough to provide a large image of small subjects. The tele-macro type lens solves this problem by producing a large, high quality image, up to life-size, while maintaining a long working distance. This can enable you to capture on film the world of photomicrography, without disturbing the subjects. The 180mm F3.5 APO MACRO lens has a very narrow field of view, and can allow very narrow depth-of-field for selective focus and less... Less

This compact ultra-telephoto zoom lens is ideal for sports, nature, wildlife, and landscape photography. The new multi layer lens coating and lens design reduce flare and ghost and also creates an optimum color balance and better picture quality through the entire zoom range. This lens uses one aspherical lens and three SLD (Special Low Dispersion) glasses for excellent correction of various chromatic aberrations. It provides excellent image quality for digital and film SLR cameras. The new multi-layer lens coating and lens design reduces flare and ghosting, and creates an optimum color balance through the entire zoom range. This lens uses one aspherical lens and three SLD (the special low dispersion) glasses for excellent correction of chromatic aberration, making high-quality images a... Less

The Sigma 135-400mm f4.5-f5.6 APO aspherical lens lets you capture an unprecedented range of images, everything from landscapes to sports. This lens uses Sigma's exclusive five-group zoom system combined with aspherical lens elements to achieve sharp, high-contrast photographic results across the entire zoom range. The lens' optics also use special low dispersion glass elements that help eliminate the secondary spectra effect normally associated with telephoto lenses. The front lens group does not rotate thanks to Sigma's rear focus system, making polarizing filters extremely easy to use. For added convenience, the 135-400mm f4.5-f5.6 APO aspherical lens includes a built-in rotary tripod mount that eliminates vibration, and consequently blurry images, during shutter release. This model... Less

The Sigma 14mm f/2.8 EX Ultra Wide Angle lens is world's shortest focal length non-fisheye wide-angle autofocus lens. The EX Series combines excellence of engineering and new technology to provide superior build and optical quality. The lens has a fast f/2.8 maximum aperture and a close focusing distance of only 7.1 inches (18cm). It also incorporates a built-in lens hood and a gelatin filter holder behind the rear lens element. With the features you need to produce the sharpest results, Sigma's fixed focal length lenses are perfect for a wide variety of uses.This ultra-wide lens can open an entire new way of producing pictures.

The large angle of view of the Sigma 12-24 4.5/5.6 EX DG ASPH Zoom (122 degree super wide angle of view at 12mm along the diagonal axis) is ideal for shooting indoors as well as landscape photography. It has a variable angle of view from 122 degrees to 84.1 degrees. Four Special Low Dispertion (SLD) glass elements are provided for effective compensation of color aberration, which is a common problem with super-wide angle lenses. Two pieces of Glass Mold and one-piece Hybrid aspherical lenses offer excellent correction for distortion as well as all types of aberration. By effective arrangement of lens elements and advanced technology this lens has Super Compact dimensions of 100mm full-length, and 87mm Maximum Diameter. It is equipped with an Inner Focusing System that will keep the... Less

Sigma 18-50mm F3.5-5.6 DC Lens for Nikon SLR Digital Camera 521-306 - This zoom lens was exclusively designed to suit the characteristics of digital SLR cameras. The image circle was designed to match the size of the image sensors of digital SLR cameras, and this produced a compact lens with a maximum diameter of 60mm (2.3in.), overall length of 67.5mm (2.6in.) and weight of only 245gr (8.6 ounces). It has a variable angle of view of 69.3degree~27. 9degree. The use of aspherical lenses provides correction for various aberrations throughout the entire zoom range and produce high level of optical performance. 18-50mm F3.5-5.6 DC lens has a minimum focusing distance of 25cm (9.8in.) at all focal lengths and is capable of macro photography with a maximum magnification ratio of 1:3.5.
