The Sigma APO 70-200 mm f/ 2.8 EX DC OS HSM

In February, 2010 Sigma announced the Sigma APO 70-200 mm f/2.8 EX DG OS HSM. It is a telephoto fast zoom lens of the second generation with an optical stabilizer (4 f-stops), which allows you not only to shoot shorter exposures but also to see a stabilized image in a viewfinder.

Its optical scheme has two FLD ("F" Low Dispersion, analogous to fluorite glass)  and three SLD elements, providing color correction and minimization of most aberrations.

When used on APS-C (crop) cameras, an equivalent focal length is 112- 320 mm.

The minimum aperture of 2.8 and the optical stabilizer enables shooting in poor lighting conditions without a tripod or a flash.

 The Sigma APO 70-200 mm f/2.8 EX DG OS HSM has a rounded 9-blade aperture. It produces very beautiful blurring of out-of-focus areas (bokeh).

Thanks to a new hyper sonic motor (HSM), focusing is rather fast, silent and precise. Manual adjustment of sharpness is available.

For a convenient use of polarized and gradient filters the front lens is non-rotating.

The 1.4x EX DG APO and  the 2x EX DG APO teleconverters can be optionally used to increase the range of focal lengths lens up to 98-280 mm (lens speed F4, autofocusing is possible) and 140-400 mm (lens speed F5.6, autofocusing is possible) respectively.

The Sigma APO 70-200mm f/2.8 EX DG OS HSM is a good choice for portrait, genre, candid  and marriage photography.  According to its characteristics, the lens is fit for many other types of photography.

The lens comes complete with a petal hood, tripod ring and a soft case. There is an additional adapter, enlarging the hood, supplied for digital APS-C cameras.

 

Notes:

* The lens cannot be used on Pentax  cameras with the 1.4x EX DG APO  and the 2x EX DG APO teleconverters.

* The optical stabilizer for the Nikon F won't function on film cameras, except for  Nikon F6.

* The optical stabilizer for the Canon EF won't function on film cameras, except for  Canon EOS-1V.

* Both the autofocus and the system of optical stabilization won't function on Pentax film cameras and on digital  * IST and K100D cameras.

* Both the autofocus and the system of optical stabilization won't function on Minolta film cameras.

* Lenses for digital Pentax and Sony have a built-in system of optical stabilization. If you want to use the Sigma OS , you should switch off a sensor-shift system of optical stabilization.
