Sigma 18-200mm F3.5-6.3 DC HSM "C" Sony

Sigma 18-200mm F3.5-6.3 DC HSM "C" Sony The Sigma 18-200mm F3.5-6.3 DC OS HSM "C is a zoom objective with a wide-angle range of 18mm (comparable to 27mm on a full frame camera) to 200mm telezoom (comparible to 300mm on a full frame camera). Compared to the previous 18-200mm models of Sigma, this objective is 11% compacter (from 75.3mm to 70.7mm) and lighter in weight and moreover, it contains a macro function. The optical performances are more improved to by using SLD (Special Low Dispersion) glass elements with a high refraction index and excellent correction of chromatic aberration in the telezoom range. The aspheric lens parts, two-sided aspheric elements included, take care of the correction of distortion Features of the Sigma 18-200mm F3.5-6.3 DC OS HSM "C" Lens construction: 16 elements in 13 groups Angle of view: 76.5°-8.1° Minimal focal distance: 39cm Optical stabilization function Solid messing bayonet for more accuracy and a longer durability Filter measure: 62mm Close-up photography One of the most important characteristics of this objective is that the subjects can be captured as close as with the macro objectives. The minimal focal distance (measured from the camera sensor to the subject) is only 39cm with a magnification of 1:3. The workable distance (front lens to subject) is 14,7cm measured with maximal magnification. During the development of the objective, the developers took all the details in account, like for example the preventing of reflection during macro photography by engraving the product name in the objective instead of printing it. . Thermally Stable Composite What’s new, is the use of TSC (Thermally Stable Composite) that behaves itself the same during temperature changes as aluminium and metal. This is way an even bigger optical precision can be reached and why compacter parts can be used. Super Multi-layer coating The Super Multi-layer coating reduces flare and ghosting and takes care of a high contrast and sharp images, even when there’s a backlight. The specially designed hood helps even better. Hyper Sonic Motor The HSM (Hyper Sonic Motor) takes care of a high AF (Auto Focus) speed and is very silent too. Thanks to the last AF algorithm, an even better functioning AF is reached. User-friendliness The product lines “A”, “C” and “S” of Sigma contain rubber in the part of the hood that connects to the objective. This offers you a better operation and grip. Moreover, the design of the AF/MF button has improved. Content of the package Hood (LH676-01) Front lens cap (LCF-62 III) Back lens cap (LCR II)
