shutter speeds approximately 4 stops lower than would otherwise be possible. It makes telephoto shooting easy for many types of photography such as sport and nature. As compensation for camera shake is visible in the viewfinder, the photographer can easily check for accurate focus and ensure there is no subject movement. The SLD (Special Low Dispersion) glass element provides excellent correction for all type of aberrations. The Super Multi-Layer Coating reduces flare and ghosting and provides high contrast images throughout the focal range. The lens has an overall length of 126.5mm (5.0"), maximum diameter of 76.5mm (3.0") and weight of just 610g. Its compact construction makes it convenient for travel and hand held telephoto photography. This lens...  (less)

filters and has a focus limiter (eg. Full Range; - 15.8 in.; 14.6 in. - 12.3 in.).A "focus-free" mechanical design allows the lens to auto focus without any interference from the manual focus ring. This makes it easier to hold the lens without affecting the speed or normal operation of the autofocus function. Rugged mechanical construction also makes it durable enough for even the heaviest use required by professional photographers.The Sigma 105mm f2.8 EX Macro features the new deluxe external EX finish. These features and other Sigma optical advances, including an uncommonly broad range of focus, make this an ideal lens for a wide variety of applications, from nature photography to portraits.A handy screw-in type metal ...  (less)

zoom range. Maximum magnification of 1:2.3 enables close-up photography like a macro lens. This lens design and multi layer lens coating reduce flare and ghosting, which is a common problem with digital cameras. A Special Low Dispersion (SLD) lens and two aspherical lens elements provide excellent correction for all types of aberrations and produce a high level of optical performance throughout the entire zoom range.This lens offers a large aperture of F2.8 at 17mm wide angle and yet it is compact, with an overall length of 82.5mm (3.2") and diameter 79mm (3.1"). It performs superbly even in relatively low light conditions indoors or at dusk.The lens design incorporates an inner focusing system, which ensures fast AF speed as well as prevents the front...  (less)

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. It is the ideal lens for several type of photography such as wide-angle, telephoto and close-up. SLD (Special Low Dispersion) glass, a molded glass aspherical lens and two hybrid aspherical lenses provide excellent correction for all types of aberrations. The super multi-layer coating reduces flare and ghosting. High image quality is assured throughout the entire zoom range. This lens has a minimum focusing distance of 35cm (13.8") at all focal lengths, and has maximum magnification of 1:3.8, making it...  (less)

high image quality throughout the entire zoom range. The incorporation of HSM (Hyper-Sonic Motor) ensures quiet and high-speed auto focus. The OS (Optical Stabilizer) function effectively eliminates the effects of camera shake so subjects can be easily and clearly seen in the viewfinder as well as in the image. It allows the use of shutter speeds up to 4 stops slower than normal for steady, handheld photography. For Sony and Pentax mounts the built-in OS System allows the photographer to see the stabilized image in the viewfinder and can be used as an alternative with cameras having built-in image stabilization. The Super Multi-Layer Coating reduces flare and ghosting and provides high contrast images throughout the entire zoom range. This le...  (less)

SLR cameras. This new medium telephoto macro lens employs a new design concept for digital SLR cameras. Its new lens power layout produces an excellent optical performance and also reduces flare and ghost. This new lens is designed to reduce the influence of harmful light caused by reflections from the digital image sensor.MACRO 105mm F2.8 EX DG lens is very suitable for taking pictures in nature and it enables to use of natural light conditions or flash. The greater working distance of this lens is very advantageous when taking the picture of a flower among the branches or an insect. You do not shake your subject when you want to take its precise details without blurring by using a tripod. The narrow angle of view is a great aid for simplifying backgro...  (less)
