This 500mm super telephoto lens with Image Stabilizer system and large aperture of f/4 is sure to have wide appeal. Its newly designed optical system consists of 17 elements in 13 groups, including one fluorite lens and two UD lenses. These have eliminated all kinds of aberrations to achieve a level of image quality previously impossible to attain. With ring USM and an improved drive algorithm, its autofocus is the fastest in the world (when used with the EOS-3). The large f/4 aperture permits the use of autofocus when using an extender. The lens's closest focusing distance has been reduced to only 4.5m/ 14.8ft., and it is equipped with full-time mechanical manual focus, a focus preset function, and an AF Stop function. The use of a magnesium alloy for the lens barrel minimizes weight and the lens offers superior dust-proof and moisture-proof performance.

The Canon EF 35mm f/1.4L USM is a large-diameter wide-angle lens with f/1.4 capability that optimizes brightness. It is the successor to the EF 24mm f/1.4 USM and further complements the Canon L-series of wide-angle lenses. The optical system includes a polished aspherical lens along with a floating element, providing high image quality with outstanding correction for both wide f/1.4 aperture and aberration effects and outstanding definition over the entire image area. In addition, the lens' ring USM and silent AF operation make it an outstanding L-series lens for both professional and advanced amateur users.

The EF 24mm f/1.4L USM is the professional wide-angle lens with an ultra-large maximum aperture of f/1.4. This is the first EF lens to employ both a replicated aspherical lens element to suppress distortion and spherical aberration, and a UD lens element to correct lateral chromatic aberration. Thanks to the floating construction, excellent corner-to-corner delineation is attained from 25 cm to infinity.

Designed for the new c-Class BladeSystem enclosure, the HP GbE2c Ethernet Blade Switch for c-Class BladeSystem (GbE2c) provides a full set of industry standard Gigabit Ethernet Layer 2 features, sixteen internal downlinks, five uplinks and two internal cross-connects in a single low-cost blade solution. The GbE2c dramatically reduces cabling, power and cooling requirements compared to stand-alone switches, allowing you to realize the full cost saving capabilities of the HP c-Class BladeSystem.

The EF100-400mm f/4.5-5.6L IS USM is the first EF telephoto zoom lens with a high-magnification zoom range of 100 to 400mm. This is the first L type zoom lens with IS (Image Stabilizer) system. The dual-mode IS mechanism corrects camera shake blurring equivalent to two shutter speed steps. The IS Mode-1 works for normal shooting and IS Mode-2 is suitable for panning shots of a moving subject, stabilizing images in viewfinder. The optical system uses one artificial crystal fluorite and one Super UD (Ultra-low Dispersion) glass lens elements (3rd and 7th), which thoroughly correct chromatic aberration. The minimum focusing distance of 1.8m is achieved throughout zooming range. The floating system in rear focusing system is employed for the first time for EF zoom lens to achieve a high definition for the entire focusing range. A ring USM (Ultrasonic Motor) drives high-speed and silent AF and full-time manual focusing. Linear zooming design with zooming friction adjustment ring gives a good operability of this lens.
