Product Description
Bring your photographic subjects closer with this Canon EF-S 55-250mm f/4-5.6 IS Image Stabilizer Telephoto Zoom Lens. It is designed with Canon's Optical Image Stabilizer technology and is compact and light. This 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). The image stabilizer effect is equivalent to a shutter speed about 4 stops faster than the same size lens without Image Stabilizer. In other words, if the slowest shutter speed you could formerly hold a 250mm lens steadily was 1/250th of a second, with Canon's 4-stop stabilization correction, you could hand-hold at shutter speeds as slow as 1/15th of a second. It also uses a UD-glass lens element to correct chromatic aberration for excellent image quality throughout the zoom range. Filter Size - 58mm Max. Diameter - x Length 2.8 in. x 4.3 in./70 x 108mm (maximum lens length) Weight - 13.8 oz./390g Canon 1 year limited warranty

Amazon.com Product Description
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.

Editorial Reviews:Product DescriptionThe GF1 adopts the micro four thirds system standard, which was developed as an extended version of the four thirds system standard for digital camera systems. By using this standard and developing a camera body that eliminates the mirror box and optical viewfinder unit, Lumix was able to achieve a dramatic reduction in both size and weight compared with conventional digital SLR cameras, to create a new-generation system camera that features full-time live view, high-speed, high-precision contrast AF, HD movie recording, and more. The GF1 is small enough to take anywhere yet sophisticated enough to take you as far into photography and movies as you want to go.The 4/3-type 12.1-megapixel live MOS sensor featured in the GF1 offers the best of both worlds the superior image quality of a CCD sensor, and the lower power consumption of a CMOS sensor. This sensor is also advantageous for photo and movie recording with its high S/N, thanks to a circuit structure that is unaffected by the noise generated in each of the circuits. It results in clear images even when taken at high ISO sensitivity.The hybrid GF1 lets you take both high-quality photos and HD movies. You can shoot breathtaking HD movies in AVCHD Lite format (MPEG-4/H.264) backed by the high sound quality of Dolby Digital Creator. And you can record for a longer time without running out of memory because AVCHD Lite stores data more efficiently than Motion JPEG while maintaining stunning image clarity and detail. A dedicated "movie record" button on the top lets you instantly start recording movies while shooting photos, so you don't miss a second of the action.
