The superb multi-purpose SAL-DT55200 55-200mm f4-5.6 telephoto zoom lens is an excellent all-around value, covering the medium to long-distance telephoto range you will use most. It also provides close minimum focusing distance of about 3 feet (.95m), for tight shots of people, natural subjects and close-up details.

The Tamron AF18-200mm F/3.5-6.3 XR Di-II LD Aspherical (IF) MACRO is a high power zoom lens designed exclusively for digital SLR cameras using the more compact (APS-C) digital size image sensors. The focal length of this lens is equivalent to approx. 28-300mm in 35mm format.

The SAL-1870 AF DT 18-70mm f/3.5-5.6(D) lens is a compact, wide-angle to mid-telephoto zoom lens specifically designed for the Sony Alpha and Minolta Digital SLR cameras. Optics have been optimized for a small diameter image circle in order to work with the APS-C size CCD used with digital SLR cameras. When used with a digital SLR camera, the equivalent focal length for this lens is 27-105mm, ideal for snapshots, portraits, interiors and more - an excellent all-around lens to travel with.

The Sony AF-D 75-300mm lens is a general telephoto 4x zoom lens, ideal for sports, portraiture, animals etc. The telephoto effect of this lens makes the picture look compressed or have excellent background blur. When used with the Sony Alpha digital camera, the equivalent focal length (in 35mm terms) for this lens is 112.5mm to 450mm.

The Sigma 1.4x DG EX APO Tele Converter (also known as a tele-extender) will multiply the focal length of the existing lens by 1.4x, and will cut back the amount of light by one f/stop. For example, using a 1.4x teleconverter with a 300 mm lens will effectively increase the focal length to 420mm. A lens set to f/2.8 will now be f/4.

The compact and lightweight (5.6 oz, 160 g) Sigma APO Teleconverter 1.4x EX DG is a high-quality extender that preserves the image quality of the lens it's mounted to and multiplies its focal length by 1.4x without any variation in the minimum focusing distance. This teleconverter, equipped with a Sony/Minolta mount, features Sigma's new multi-layer coating to reduce flare and ghosting, which is a common problem with digital cameras.

The Sigma 70-300mm 4-5.6 DG Macro lens is the compact and economical choice for a telephoto zoom lens. Capable of macro photography, this lens has a 1:2 maximum close-up magnification at the 300 mm focal length. It is the ideal high performance lens for portraits, sports photography, nature photography, and other types of photography that frequently use the telephoto range.

The Sigma 2x EX APO Tele Converter (also known as a tele-extender) will multiply the focal length of the existing lens by 2x, and will cut back the amount of light by 2 f/stops. For example, using a 2x teleconverter with a 300 mm lens will effectively increase the focal length to 600 mm. A lens set to f/2.8 will now be f/5.6.

The Sigma APO Teleconverter 2x EX DG (also known as a tele-extender) will multiply the focal length of the existing lens by 2x, and will cut back the amount of light by 2 f/stops. For example, using a 2x teleconverter with a 300 mm lens will effectively increase the focal length to 600 mm. A lens set to f/2.8 will now be f/5.6.

This compact high zoom ratio lens incorporates Sigma's original OS (Optical Stabilizer) function. This system uses two sensors inside the lens to detect vertical andhorizontal movement of the camera and works by moving an optical image stabilizing lens group to effectively compensate for camera shake. It offers the use of shutter speeds approximately 4 stops slower.

The Sigma 18-50mm f/2.8-4.5 DC OS HSM is a lens dedicated to digital SLR cameras with APS-C size image sensors offering a large aperture and Sigma's Optical Stabilization and provides a high level of optical performance. The combination of the large aperture of f/2.8 and anti-shake function makes capturing exceptional photos in low light achievable, and the wide angle is well suited for indoor photography.

The Sigma 70-300mm f/4-5.6 DG OS Telephoto Zoom makes telephoto shooting easy for many types of photography such as sport and nature. The lens is built with Special Low Dispersion Glass (SLD) elements to provide corrections for all types of aberrations. Its super-multi-layer coating adds to the excellence of images by reducing flare and ghosting, yielding high contrast images throughout the focal range.
