(From Sony lens literature) The Sony DT 55-200mm F4.5-5.6 SAM (SAL552002) is a 3.6x telephoto zoom lens with an extremely versatile 55mm to 200mm focal length range (35mm-format camera equivalent: 82.5-300mm). It is designed exclusively for use with α digital SLRs incorporating an APS-C type image sensor. Weighing only 305g (approx.), it offers high telephoto zoom power in a package that is light, compact, and easy to carry. And with a minimum focusing distance of 0.95m and a max. magnification ratio of 0.29, it can be used for macro shooting, too. Smooth AF operation is assured by a newly developed Smooth Autofocus Motor (SAM).
Compact and lightweight with 3.6x zoom
The DT 55-200mm F4.5-5.6 SAM is a 3.6x (approx.) telephoto zoom lens designed specifically for use with α DSLRs that have an APS-C type sensor. It is exceptionally light and compact, with a weight of only 305g and dimensions of 71.5mm (max. diameter) x 85mm (length) that make it very easy to handle and carry.
High telephoto power 55-200mm zoom
Wide-ranging 55-200mm zoom coverage (35mm-format equivalent: 82.5-300mm) enables this lens to be used for portraits and landscapes, as well as dramatic telephoto close-ups of sports action, wildlife, and other subjects that are hard to get close to.
ED (Extra-low Dispersion) glass element for superior imaging with minimal colour aberration
An ED glass element is incorporated into the lens optics to assure clear, sharp imaging, with reduced colour aberration even at high-power telephoto settings. In addition, a circular aperture mechanism is used to assure smoother, more beautiful background defocusing.
Newly-developed Smooth Autofocus Motor (SAM) for smooth AF operation
The DT 55-200mm F4.5-5.6 SAM's focusing lens group is driven by a new Smooth Autofocus Motor (SAM) in the lens itself, instead of a motor in the camera body. Responding instantly to AF drive control signals from the camera, the motor delivers power with smoothness and precision.
0.95m minimum focusing distance, 0.29 maximum magnification ratio
With a class-leading minimum focusing distance of just 0.95 meters and a maximum magnification ratio of 0.29, the DT 55-200mm F4.5-5.6 SAM can also be used to take macro close-ups.
