The Sigma 70-200mm F2.8 EX DG OS HSM is the second generation of large-aperture telephoto zoom lenses incorporating Sigma’s OS (Optical Stabilizer) anti-shake system. It offers the equivalent of shooting at shutter speeds 3 to 4 stops slower than without OS, thus allowing handheld telephoto zoom shooting even in poorly lit conditions. Its HSM ensures quiet and high speed AF as well as full-time manual focusing.
It features a large maximum aperture of f/2.8 that remains constant throughout the zoom range, making it incredibly valuable when shooting in low light situations such as wedding or other events. It is also great when shooting fast-moving subjects such as sports, when fast shutter speeds are needed to capture fleeting moments. The 70-200mm f/2.8 is fast and versatile and at a length of 7.8 (19.8cm) will be a tool that seldom sees the inside of your camera bag. The lens comes with a petal-type lens hood plus an adapter to extend its length for users with APS-c cameras.

This large aperture zoom lens has improved optical performance and retains close-up ability with a minimum focusing distance of 100cm/39.4 in. and maximum magnification ration of 1:3.5. This lens is suitable for taking all type of subjects such as portraits, landscape, and close-up pictures. Two SLD (Special Low Dispersion) and three ELD (Extraordinary Low Dispersion) glass elements provide excellent correction for all types of aberrations. High image quality is assured throughout the entire zoom range. The super multi-layer coating reduces flare and ghosting. This lens incorporates HSM (Hyper Sonic Motor), which ensures a quiet and high-speed AF as well as full-time manual focusing capability. The lens design incorporates an inner focusing and inner zooming systems. The overall length of the lens does not change during focusing and zooming, ensuring convenient handling. A removable tripod collar (TS-21) is included as a standard component.

Unparalleled optical performance in a fast and steady telephoto zoom: In the pursuit to achieve the most outstanding image resolution in the 70-300mm class, Tamron’s Anniversary lens – the SP AF 70-300mm F4-5.6 Di VC USD (Model A005) – utilizes an advanced optical design that features an LD (Low Dispersion) and an XLD (Extra Low Dispersion) lens element made from specialized materials that prevent chromatic aberration. As a result, the SP AF70-300mm F4-5.6 Di VC USD (Model A005) boasts sharper contrast and greater descriptive performance than all others in its class. In addition, it is the first Tamron lens sporting a USD (Ultrasonic Silent Drive), Tamron’s very own ultrasonic auto-focus drive mechanism. This USD mechanism delivers fast focusing, making it a perfect telephoto zoom choice for photographing sports, racing, or other fast-moving subjects. The lens also boasts Tamron’s proprietary VC (Vibration Compensation) image stabilization to assist in hand-held photography, not only at long focal length ranges where blurring is common, but also under low-lit conditions, dramatically enhancing photographic freedom. This comnbination of best in class image resolution, Ultrasonic Silent Drive and Vibration Compensation is a new achievement of Tamron technology, culminating in the production of a premium 70-300mm telephoto zoom lens.

While the AF-S NIKKOR 24-120mm f/4G ED VR Zoom Lens from Nikon is designed primarily for use with FX-format D-SLR cameras, it’s equally at home on any DX-format D-SLR camera. As a standard 5.0x zoom on an FX-format camera body, it’s perfect for landscapes, portraits, and weddings – it’s an excellent choice for a perfect take-along-everywhere lens. On a DX-format camera, the focal length gets a 1.5x bump that turns it into a formidable longer-range optic with enough wide angle for all but the widest of shots.

The AF-S 24-120 ED VR is a versatile imaging tool with a constant maximum aperture of f/4.0 – this enables photographers to maintain exposure settings throughout the entire zoom range. For those critical focusing-moments – the M/A focus mode switch allows the shooter to quickly change between manual and autofocus modes.
