Canon EF 70-300mm f4-5.6 IS USM Lens for Canon EOS SLR CamerasN

Featuring the latest 3-stop Image Stabilizer for outstanding camera shake reduction, the 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 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 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 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.

The EF 70-300mm f/4-5.6 IS USM telephoto zoom lens has been developed to meet the high-performance standards that today’s photographers demand. Improved Image Stabilizer Technology provides up to three stops of “shake” correction, and the “Mode 2″ option stabilizes images while panning with a moving subject. Compared to the original Canon EF 75-300mm IS zoom lens, this telephoto lens has faster autofocus, and overall the lens is lighter and has a smaller diameter than the original. The zoom ring can be locked at the 70mm position, making this powerful lens easy to transport, too.

Nikon 70-300mm f/4.5-5.6G ED IF AF-S VR Zoom Nikkor Lens for Nikon Digital SLR Cameras

The Nikon 4.3x, 70-300mm f4.5-5.6G ED-IF AF-S VR Zoom-Nikkor lens is ideal for telephoto shooting opportunities. It incorporates many of Nikon’s most advanced lens design attributes such as Extra Low Dispersion (ED) glass, Silent Wave Motor technology (SWM) and Enhanced Vibration Reduction (VR II), in a design engineered for use with both Nikon DX format digital and 35mm film SLR cameras. With a high-powered 70-300mm focal length range, the lens is ideal for sports, action, wildlife, travel and portrait photography, among other telephoto applications. When used on a Nikon DX format digital SLR, this lens approximates the picture angle performance of a 105-450mm lens on a 35mm SLR camera.

Beyond the lens’ 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 advanced 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 70-300mm f4.5-5.6G ED-IF AF-S 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 characteristics.

The AF-S VR 70-300 f/4.5-5.6G IF-ED is a high-performance super telephoto zoom lens that has been designed to meet the demands of both digital and 35mm format SLR users. It offers a 4.3x zoom with a range of 70-300mm (105-450mm on a DX Nikon D-SLR) and features ED (Extra-low Dispersion) glass elements that ensure superior optical performance. This lens incorporates Nikon’s second-generation vibration reduction system (VR II) that allows flexible hand-held shooting by stabilizing the image to the equivalent extent of using a shutter speed that is four stops faster when compared with a conventional lens (as determined by Nikon performance test). The SWM (Silent Wave Motor) and IF (Internal Focusing) ensure fast and quiet focusing action, and the nine-blade rounded diaphragm makes out-of-focus elements blend smoothly to produce natural-looking, harmonious backgrounds.

Canon EF 50mm F1.8 II lens: Highly Recommended by dpreview.com

The Canon EF 50mm F1.8 II may be one of the cheapest lenses currently on the market, but its optics belie its lowly price. As befits a classic standard prime lens, it’s very sharp when stopped down (especially in the centre), shows minimal chromatic aberration, and has relatively low distortion; APS-C users will also benefit from extremely low vignetting. In most regards it comes very close indeed to its much more expensive bigger brother, the EF 50mm F1.4 USM, lagging marginally behind in corner sharpness at any specific aperture. The only real blight in imaging terms is the lens’s bokeh, or rendition of out-of-focus backgrounds, which is anything but smooth with a distinct tendency to render bright highlights as obvious pentagons (it’s a pity Canon didn’t choose to use a diaphragm with 7 or 8 blades instead of 5).

Amazon.com Product Description Lightweight and affordable, the Canon EF 50mm lens–which offers a fast f/1.8 aperture–is an excellent lens for people who prefer a fixed focal length. Canon’s lightest EF lens at a mere 4.6 ounces, the lens boasts a traditional Gauss-type optical design that delivers a sharp performance even when wide open. As a result, the lens provides an image that’s extremely close to how your eye perceives a subject, making it excellent for portraits and images that require a natural depth of field. In addition, the lens focuses as close as 18 inches, helping you take extreme close-ups. Finally, the lens offers an excellent color balance. As with all Canon lenses, the lens carries a one-year warranty.

• Focal length: 50mm
• Maximum aperture: 1:1.8

Canon EF-S 55-250mm f/4.0-5.6 IS Telephoto Zoom Lens for Canon Digital SLR Cameras

Incorporating Canon’s Optical Image Stabilizer technology, this Canon 55-250mm telephoto zoom lens captures long distance, low-light shots far better than many comparable lenses, helping you photograph the far-off action of athletes or zoom in for an intimate portrait with a blurred background. The high-zoom-ratio lens is equivalent to a focal length of 88-400mm in the 35mm format (when used on Canon EOS cameras compatible with EF-S lenses). More significantly, the image stabilizer effect creates an equivalent shutter speed of roughly four stops faster than the same size lens without an image stabilizer. In other words, if the slowest shutter speed you can hold a 250mm lens steadily is normally 1/250th of a second, this Canon lens will let you hand-hold shutter speeds as slow as 1/15th of a second. The lens also boasts a UD-glass lens element to correct chromatic aberration to create excellent image quality throughout the zoom range. Delivering an excellent performance at an affordable price for all photographers, the 55-250mm lens carries a one-year warranty.

Specifications

• Focal length: 55-250mm
• Maximum aperture: f/4 to f/5.6
• Lens construction: 12 elements in 10 groups, including one UD-glass element
• Diagonal angle of view: 27 degrees (at 50 feet) to 6 degrees (at 15 feet), with APS-C image sensors
• Focus adjustment: DC motor, gear-driven (front focusing design)
• Closest focusing distance: 3.6 feet (0.31x maximum close-up magnification)
• Filter size: 58mm
• Dimensions: 2.8 inches in diameter and 4.3 inches long
• Weight: 13.8 ounces
• Warranty: 1 year
