Sigma is pleased to announce the launch of the new 10-20mm F4-5.6 EX DC HSM lens. Covers a superwide angle of view 102.4 to 63.8-degrees (SD format) Three pieces of Special Low Dispersion (SLD) elements and three aspherical lens elements produce top quality optical performance. Inner focusing system ensures the length of the lens remains unchanged whilst controlling aberrations. Equipped with HSM (Hyper Sonic Motor) system Minimum focusing distance of 9.4″ (24cm) at all focal lengths. Relatively compact, lightweight for an ultra wide-angle zoom lens. The Super wide-angle zoom lens designed exclusively for digital SLR cameras 10-20mm F4-5.6 EX DC HSM lens allows enjoyment of super wide-angle photography and it is a very powerful tool for indoor shooting and landscape photography with APS-C size image sensors of digital SLR cameras. Wide angle of view (102.4-degrees at 10mm and 63.8-degrees at 20mm) offers the photographer greater freedom of expression. Three SLD glass elements are employed for effective compensation of color aberration, which is a common problem with super-wide angle lenses. One piece of glass mold and two hybrid aspherical lenses, offer excellent correction for distortion, as well as all types of aberration. This lens is equipped with an inner focusing system, and the models which are equipped with HSM system provide quiet, high speed autofocus shooting and also offer full time manual focusing. It has a minimum focusing distance of 9.4 (24cm) at all focal lengths. The non-rotating lens barrel perfectly suits the petal shaped lens hood. A circular polarizing filter can also be used conveniently.

The AF-S DX NIKKOR 18-200mm, the next generation of Nikon’s all-time best-selling premium high-ratio zoom, combines an 11X zoom range with VR II to provide DX-format enthusiasts with an extremely versatile zoom range in a compact form-factor. Nikon enhanced construction to include a zoom lock switch, to allow photographers to secure the lens barrel at its minimum length, eliminating the natural gravitational effect that can draw the barrel downward during transport. The inclusion of Nikon’s exclusive Super Integrated Coating (SIC) reduces instances of ghosting or flaring. Whether shooting artistic landscapes or vacation snapshots, this lens provides fast and quiet AF operation with the help of Nikon’s SWM technology. Designed to be a one-lens solution and weighing in at a scant 19.9 ounces and measuring only 3.8 inches in length, this lens provides an extraordinary (35mm equivalent) picture angle of 27-300mm when mounted on any Nikon DX-format camera such as the new D300s or D3000 D-SLR cameras. Additionally, the optical formula contains two ED glass elements and three aspherical lenses to minimize chromatic aberration and distortion. The resulting images exhibit extreme sharpness, extraordinarily vibrant color and crisp contrast. 11x Zoom versatility A remarkable 18-200mm one-lens solution?adept in a wide variety of situations. Picture angle equivalent of a 27-300mm lens in 35mm format. Nikon VR II (Vibration Reduction) image stabilization Vibration Reduction, engineered specifically for each VR NIKKOR lens, enables handheld shooting at up to 4 shutter speeds slower than would otherwise be possible, assuring dramatically sharper images. Two Extra-low Dispersion (ED) elements Offers superior sharpness and color correction by effectively minimizing chromatic aberration, even at wide aperture settings. Three aspherical lens elements Virtually eliminates coma and other aberrations, even at wide apertures. Zoom lock switch Secures lens barrel at its minimum length. Nikon Super Integrated Coating (SIC) Enhances light transmission and offers superior color consistency and reduced flare. Exclusive Nikon Silent Wave Motor (SWM) For fast, accurate and quiet autofocus. Rounded 7-blade diaphragm Renders more natural appearance of out-of-focus image elements. Focus to 20 inches Extends versatility. M/A focus mode switch Enables quick response to changing situations between manual and autofocus operation. Flower-shaped lens hood Included HB-35 lens hood?shades the objective from unwanted, image-degrading light.

The AF-S VR Zoom-Nikkor 24-120mm f/3.5-5.6G IF-ED lens adds a powerful third zoom lens to Nikon’s line of Vibration Reduction (VR) lenses. VR is an advanced Nikon technology that overcomes one of the fundamental problems photographers face while photographing under conditions where it is difficult to hold the camera steady. VR technology helps eliminate image blur caused by camera shake, particularly when shooting in low-light conditions, allowing photographers to use shutter speeds about three times slower than they would ordinarily use to get sharp, well exposed images.In addition to a compact design for easier handling, the AF-S VR Zoom-Nikkor 24-120mm f/3.5-5.6G IF-ED lens features Nikon’s exclusive Silent Wave Motor Technology for fast, accurate and nearly silent focusing as well as a broad 5x zoom range that covers a variety of picture taking conditions from wide scenic landscapes to dramatic portraits and close-up pictures. Its VR technology offers photographers a wider range of picture taking conditions, while ensuring consistently sharp images. The versatility the AF-S VR Zoom-Nikkor 24-120mm f/3.5-5.6G IF-ED lens makes it an ideal addition to any Nikon photographer’s camera bag. The AF-S VR Zoom Nikkor 24-120mm f/3.5-5.6G IF-ED offers a versatile focal range from wide-angle to telephoto and also gives photographers an unprecedented control over their pictures in a wide variety of difficult and tricky situations. Nikon’s advanced Vibration Reduction technology allows photographers to use slower shutter speeds, yet achieve sharper, crisper pictures than before, and with Nikon’s exclusive Silent Wave Motor Technology for nearly instant autofocus response – overall image sharpness quality is raised to new levels. In addition to Vibration Reduction, the AF-S VR Zoom-Nikkor 24-120mm f/3.5-5.6G IF-ED lens includes a selection of Nikon advanced technologies such as Manual/Automatic mode, two Extra Low Dispersion (ED) glass elements and two Aspheric lens elements, Silent Wave Motor Technology (SWM), Internal Focusing construction (IF), Super Integrated Coating (S-IC) and G-Type design. Offered exclusively in Nikon’s AF-S optics, the Manual Automatic mode (M/A) allows instant switching between autofocus and manual focus, virtually eliminating lag time in the transition and enabling photographers to make a last minute manual adjustment, even if the autofocus system has locked onto the subject. This performance is complimented by Nikon’s Autofocus Tracking with Lock-on(R), a technology that enables the system to maintain sharp focus even if the subject is momentarily obscured from view or moves off the camera’s AF sensor. Extra Low Dispersion (ED) Optical Glass is a high quality, low dispersion glass that enables superior performance in the AF-S VR Zoom-Nikkor 24-120mm f/3.5-5.6G IF-ED lens. Through low dispersion characteristics the lens’ color performance is enhanced by virtually eliminating secondary chromatic aberration. This technology

Compact, Lightweight and Durable construction with diameter of 70mm (2.8 in.), length of 78.1mm (3.1 in.) and weight of 405g./14.3oz. Lens has Metal Mount. Minimum focusing distance of 45cm (17.7 in.) at all focal lengths.Compact, Lightweight Superzoom lens, with high zoom ratio 11:1This high zoom ratio lens is exclusively designed for digital SLR cameras and capable of covering a wide range of focal lengths from wide-angle to telephoto. Two Special Low Dispersion (SLD) glass elements and two hybrid aspherical lenses offer the utmost correction for all types of aberrations, and enables this extended range super zoom lens to be housed in a compact and lightweight construction of 70mm (2.8 in.) diameter, and 78.1mm (3.1 in.) in length, and weighing just 405g/14.3oz. The new lens coating reduces flare and ghost, which is a common problem of digital cameras and also creates an optimum color balance. This lens has a minimum focusing distance of 45cm (17.7 in.) at all focal lengths and has maximum magnification of 1:4.4. The lens design incorporates an inner focusing system, which prevents the front of the lens from rotating, making it particularly suitable for using circular polarizing filters and petal shaped lens hoods. The overall length of the lens does not change during focusing, ensuring convenient handling and ease of use. A zoom lock switch eliminates zoom creep during transportation, a convenient addition when traveling.
