Sigma Expands Multiple Lens Compatibility

Sigma’s range of lenses has expanded with the release of several new variants of already known models. In particular, the company introduced a wide-angle zoom 10-20mm F4-5.6 EX DC HSM and APO 70-200mm F2 lens.8 II EX DG MACRO HSM 4/3 version. The second of the named models and the APO 50-150mm F2 lens.8 II EX DC HSM also available in Pentax and Sony mounts. Finally, a new modification of the APO 70-300mm F4-5 model.6 DG MACRO is designed for use with Nikon cameras.

Lens 10-20mm F4-5.6 EX DC HSM (top image) for DSLRs categorized as ultra wide-angle lenses. It provides a viewing angle of 94.5?-56.8?. Low dispersion glass elements and aspherical lenses are incorporated to reduce distortion. Fast and quiet focusing is provided by an ultrasonic drive.

Fast APO 70-200mm F2 lens.8 II EX DG MACRO HSM (second shot) covers a wide range of focal lengths and enables macro photography at a minimum focusing distance of 1 m (maximum magnification is 1: 3.5). The optical design of the lens includes elements made of glass with low and ultra-low dispersion. Like the previous model, the lens is equipped with an ultrasonic focusing drive.

APO 50-150mm F2 Lens.8 II EX DC HSM (third shot) exclusively for digital SLR cameras. Among the distinctive features of this model, the manufacturer notes a universal range of focal lengths, a high constant aperture and the use of a new, ultra-multilayer coating of elements.

Model APO 70-300mm F4-5.6 DG MACRO is equipped with an autofocus motor, which makes it possible to use the lens with any Nikon cameras, including the D40, D40x and D60. The lens provides a maximum magnification of 1: 2 at a focal length of 300 mm and has ED glass elements in its optical system. Recall that a lens similar in focal length and aperture, which is also of interest to owners of Nikon D40, D40x and D60 cameras due to the presence of a built-in focusing drive, was recently released by Tamron.
