Tamron applies the Di (Digitally Integrated) logo to lenses with optical systems designed to meet the performance characteristics of digital SLR cameras, and this 28-75mm Di autofocus zoom lens is no exception. Boasting revolutionary downsizing XR technology, the lens is among the smallest and lightest models in the history of fast zoom lenses. In fact, it looks just like an ordinary standard zoom lens, but offers a fast constant maximum aperture that will reshape your photographic horizons. Specific details include a constant maximum aperture of f/2.8, a minimum focusing distance of 13 inches, and a rotation-type zoom. As with all Tamron lenses, the 28-75mm lens carries a six-year warranty. Lens construction: 16 elements in 14 groups Angle of view: 75 to 32 degrees Zooming type: Rotation Diaphragm blade number: 7 Minimum aperture: f/32 Minimum focusing distance: 13 inches Macro magnification ratio: 1:3.9 (at 75mm) Filter diameter: 67mm Accessories: Lens hood Mount: Canon, Nikon, Pentax, Sony Dimensions: 2.9 inches in diameter and 3.6 inches long Weight: 18 ounces

Bring small things into full-sized view with the Canon EF 60mm macro USM lens. Macro lenses can uncover detail that would be impossible to detect by the eye and give new perspective to extremely minute subjects such as insects or the petals of a small flower, and this lens is no exception. The 60mm lens offers an angle of view that's equivalent to a 96mm lens on a 35mm camera, along with a floating optical system that can focus down to life-size 1:1 magnification. The inner focusing system, meanwhile, is driven by a silent and powerful ring-type ultra-sonic monitor (USM), meaning the lens's overall length never changes during focus. Ultimately, the multi-purpose lens is equally at home shooting macro shots, portraits, or available-light photos. Like all Canon EF-S lenses, this lens is restricted to the EOS 20D, EOS Digital Rebel, and EOS Digital Rebel XT cameras. Focal length: 60mm Maximum aperture: 1:2.8 Lens construction: 12 elements in 8 groups Diagonal angle of view: 25 degrees Focus adjustment: Manual Closest focusing distance: 0.65 feet Filter size: 52mm Dimensions: 2.9 inches in diameter, 2.8 inches long Weight: 11.8 ounces

This ultra telephoto zoom lens offers a fast aperture of F2.8 at the 500mm focal length and F5.6 at the 1000mm. It covers widely-used focal lengths from 200mm to 500mm and has a large aperture of F2.8 throughout the entire zoom range. This lens can be used to create amazing image expression with various types of photography such as astrophotography, portraits, wildlife, sports. SLD (Special Low Dispersion) glass and three ELD (Extraordinary Low Dispersion) glass elements provide excellent correction for all type of aberrations. The super multi-layer coating reduces flare and ghosting and provides high image quality from the extremely large aperture. The lens hood, designed exclusively for this lens, blocks out extraneous light. A 72mm filter can be inserted at the rear of the lens, and a circular polarizing filter can be used in situ thanks to the ingenious internal rotation mechanism. The dedicated Li-ion battery BP-21 is used to power the zooming and AF operation. This battery is built in the lens barrel. For the convenience of the photographer, focusing distances and focal lengths can be viewed on the lens' built-in LCD panel.

Designed to meet consumer demands for a fast EF-S zoom lens, the EF-S 17-55mm offers image quality on par with Canon's highly regarded L-series lenses. The lens features a large circular aperture that produces a shallow depth of field, creating background blur that draws special attention to the photographic subject. The lens construction, meanwhile, includes UD and aspherical elements that deliver impressive image quality throughout the entire zoom range. And thanks to the Image Stabilizer lens groups--which shift to compensate for camera shake--the image appears crisp and clear on the image plane, eve in dim light. Finally, the lens offers a ring-type ultra-sonic monitor (USM), inner focusing, and new AF algorithms to help achieve autofocus quickly and quietly, along with full-time mechanical manual focusing that makes it possible to manually adjust the focus even in AF mode. As with all Canon lenses, this lens carries a one-year warranty. Focal length: 17-55mm Maximum aperture: f/2.8 Lens construction: 19 elements in 12 groups Diagonal angle of view: 78 degrees (at 30 feet) to 27 degrees (at 50 feet) Focus adjustment: AF with full-time manual Closest focusing distance: 1.15 feet Zoom system: 5-group helical zoom (front group moves 27mm) Filter size: 77mm Dimensions: 3.3 inches in diameter, 4.4 inches long Weight: 22.8 ounces
