Product Description
From the ManufacturerThe Nikon 18-200mm is a compact, lightweight, 11.1x zoom lens that is ideal for high-performance, everyday photography, and it incorporates advanced features such as Nikon's Extra Low Dispersion (ED) glass, Silent Wave Motor technology (SWM), and Enhanced Vibration Reduction (VR II) in a DX-Nikkor design engineered exclusively for use with Nikon DX format digital SLR cameras. With a remarkable 18-200mm focal length range (picture angle equivalent to a 27-300mm lens in 35mm format), the lens conveniently covers everything from wide landscapes to tight portraits and action photography. Advanced Nikon engineering has lent the lens a compact, lightweight design that offers excellent handling characteristics and superb optical quality.
Beyond the lens's incredible optical versatility is the benefit of Enhanced VR II Vibration Reduction, an innovation that makes it possible to take substantially sharper handheld pictures at slower shutter speeds than would otherwise be possible. This provides the distinct advantage of being able to shoot more effectively in a much broader variety of challenging conditions. With the new Nikon VR II advantage, users can take pictures at shutter speeds as many as 4 stops slower than they ordinarily could shoot without the image-degrading blur associated with camera shake at slow shutter speeds. Nikon's VR technology further enhances picture-taking potential with a choice of two modes to match most shooting conditions. VR Normal Mode primarily compensates for camera shake, and includes automatic panning detection, as well as automatic tripod detection. VR Active Mode effectively compensates for vibration in situations where it is more pronounced and more frequent, such as when shooting from a moving vehicle.
To further ensure outstanding optical performance, the 18-200mm f3.5-5.6G IF-ED AF-S DX VR Zoom-Nikkor features two Extra-Low Dispersion (ED) glass elements and three complex aspherical lens elements that provide for higher resolution, high-contrast images while minimizing chromatic aberration, astigmatism, and other forms of distortion. The lens also features Nikon's compact Silent Wave Motor technology (SWM), which combines fast and precise autofocusing with super-quiet operation, as well as Internal Focusing (IF) construction that allows the lens to focus without changing its external size, improving balance and handling chrematistics.
All of Nikon's DX Nikkor lenses are engineered exclusively for use with Nikon DX format digital SLR cameras, making the lens smaller and lighter while providing exceptional center-to-edge-to-corner image quality and overall optical performance.

Canon EF 70-300

Product Description
From the Manufacturer
Featuring the latest 3-stop Image Stabilizer for outstanding camera shake reduction, the Canon EF 70-300mm f4-5.6 IS USM zoom lens also features super responsive autofocus. Replacing the popular EF 75-300mm f4-5.6 IS USM, the world's first interchangeable lens with Image Stabilizer (IS), the lens is expected to appeal to serious amateur nature and sports photographers looking to achieve outstanding results while shooting hand held.

Image Stabilizer
IS dramatically reduces image blur caused by camera shake. The Canon EF 70-300mm f4-5.6 IS USM features Canon's latest 3-stop IS, a one-stop improvement over its predecessor. This allows shutter speeds up to three stops slower than would otherwise be possible, with no perceptible increase in image blur. Photographers normally shooting a 300mm frame handheld at 1/500 second can obtain the equivalent result with a shutter speed of just 1/60 second, vastly extending options in low-light conditions.
Gyro sensors detect unwanted vibrations, triggering the corresponding movement of a correcting lens group perpendicular to the optical axis. This alters the light path, returning the image to its correct position on the sensor or film plane.
The Canon EF 70-300mm f4-5.6 IS USM provides 2-mode IS for shooting immobile subjects. Mode 1 stabilizes the image along both the horizontal and vertical axes. For shooting while panning to follow a moving subject, Mode 2 turns off correction in the panned direction and prevents the effect of dragging the subject back through the frame. IS switches off automatically when the camera is mounted on a tripod, thus preventing feedback loops between the IS sensor and stabilizer motor vibrations.
Superb autofocus
The micro USM motor found in the EF 70-300mm f4-5.6 IS USM employs ultra-sonic frequency vibrations to drive auto focus with unrivalled speed and near-silent operation. Good holding torque stops the lens with precision and accuracy, the instant it arrives at the correct focus point and without overshoot. A high-speed CPU and optimised AF algorithm result in a significant increase of AF speed compared to that of its predecessor.
A zoom ring locking mechanism is provided that locks the zoom at the wide-angle setting. This ensures that the lens is carried or stored in its most compact position, preventing possible damage caused by the lens extending and hitting obstacles when being carried mounted on a camera with a strap.
Pleasing defocused background
The EF 70-300mm f4-5.6 IS USM employs an electro-magnetic diaphragm (EMD) with a circular aperture. This helps create an attractive, even defocused background
when isolating a subject at large apertures.
Image quality
By optimizing Super Spectra lens coatings and lens element shaping, Canon's engineers have been effective in suppressing flare and ghosting--more prone to occur with digital cameras due to reflection off the image sensor. By increasing light absorption, coatings reduce reflections off lens element surfaces to deliver crisp, undistorted images with natural color balance.
Focal length translates to 112-480mm equivalent in 35mm film format when fitted to EOS 20D and EOS 350D cameras.
The EOS system
The EF 70-300mm f4-5.6 IS USM includes distance metering information, providing compatibility with the E-TTL II flash system of late model cameras such as the EOS-1D Mark II N and EOS 5D . When used in conjunction with Canon's range of EX Speedlite flash units, the lens passes distance information to the flash algorithm for markedly improved flash exposure metering.
Accessories for the Canon EF 70-300mm f4-5.6 IS USM include the lens hood ET-65B and the lens pouch LP1222. In keeping with Canon's Kyosei philosophy of living in harmony with the environment, the lens features only lead-free glass.
