Sony Alpha

A superb all-purpose telephoto zoom lens you can afford. The Sony SAL-DT55200 55-200mm f4-5.6 Telephoto Zoom Lens is an excellent all-around value, covering the medium to long-distance telephoto range family photographers will use most often. It also provides close minimum focusing distance of about 3 feet (.95m), for tight shots of people, natural subjects and close-up details. Its compact, lightweight design makes it easy to carry as your standard or accessory lens — and all your shots will benefit from the Sony Super SteadyShot image stabilization system built into every Sony ¿ system DSLR. (35mm equivalent: 82.5-300mm).

17-35mm f/2.8-4 EX DG Aspherical HSM is specially designed to suit the characteristics of digital SLR cameras. This lens has compact dimensions and features an overall length of 86.2mm / 3.3 in. SLD (Special Low Dispersion) glass is used for effective compensation of color aberration. Two pieces of molded glass aspherical lens elements offer excellent correction for distortion as well as all types of aberration. Excellent optical performance was realized both for Digital SLR cameras and film SLR cameras.

It has a minimum focusing distance of 27cm / 10.6 in. at all focal lengths, and maximum magnification ratio of 1:4.5. This super-wide angle lens’s useful range of view is very convenient for close-up photography.

Sigma, Nikon, and Canon models are equipped with a Hyper Sonic Motor (HSM). It is easy to revert to Manual Focus by simply turning the focusing ring and overriding the AF. An inner focus system provides high performance and convenience. The inner focus system allows the lens to be focused without having to rotate the front of the lens, so the lens accepts a petal-type hood and it is also easy to use a circular polarizing filter.

An inner focus system provides high performance and convenience. The non-rotating lens barrel perfectly suits the matched petal shaped lens hood.

With the capability to focus quickly and zoom from super-wide-angle to wide-angle, this lens captures interior scenes with greater flexibility and handles fast action in close environments. Its DT design is ideally suited for the APS-size CCD imager of the Sony® ? (alpha) DSLR-A100 camera — and its 35mm-equivalent zoom range of 16.5mm to 27mm gives you wide latitude in framing and composition.

Internal Focusing System:
Lens elements at the rear of the optical system move, allowing rapid auto-focus response.

Aspherical Lens Elements:
Aspherical elements correct frame distortion to provide more visually accurate super-wide-angle shots.

ED (Extra-low Dispersion) Glass:
ED Glass lenses minimize flare and greatly reduce chromatic aberration, giving you photos with sharper focus and more accurate color separation.

Circular Aperture:
In low-light shots or nightscapes, out-of-focus light sources have a pleasing circular defocused effect.

Designed exclusively for Minolta and Sony digital SLR cameras, the ultra-wide-angle 10-20mm offers a view from 102.4 to 63.8 degrees, making it ideal for landscape photography and other vast applications. The lens is distinguished by its three special low dispersion (SLD) glass elements, which effectively compensate for color aberration, and its aspherical lenses, which provide maximum correction for distortion and various aberrations. As a result, the lens produces an extremely high image quality throughout the entire zoom range. The HSM-equipped models, meanwhile, produce fast autofocus (AF) speeds and quiet shooting while still letting you perform full-time manual focus. Other details include a minimum focusing distance of 9.4 inches at all focal lengths and an integral petal-type hood to block out extraneous light.

Lens Elements and Coating
The new multilayer lens coating and lens design reduce flare and ghost–a common problem with digital cameras–while also creating an optimal color balance throughout the entire zoom range. At the same time, the lens offers three SLD glass elements that effectively compensate for color aberration, along with a piece of glass mold and two hybrid aspherical lenses that offer excellent correction for distortion and all types of aberration.

Inner Focusing System and HSM
The lens incorporates an internal focusing system that eliminates front lens rotation, letting you use a petal-type hood to protect from additional glare. And models equipped with a Hyper-Sonic Motor (HSM) produce silent, high-speed autofocus and full-time manual focus for Sigma, Canon, and Nikon D-mount lenses.

Best Consumer Lens
The Sigma 10-20mm lens is so respected that it was named the best consumer lens in Europe (2006) by the Technical Image Press Association (TIPA), a collection of 31 publications from 12 countries. According to TIPA, the 10-20mm lens offers a versatile range of wide-angle focal lengths, a good optical performance, and a budget price, making it an excellent investment for owners of DSLRs with APS-C format sensors. Its sharpness remains constant throughout the zoom range, and its compact size makes it an ideal companion for shooting travel, landscapes, or architectural subjects.
