This Sigma lens is the world’s first ultra telephoto zoom lens that offers a fast aperture of F2.8 at the 500mm focal length and F5.6 at the 1000mm. It covers widely used focal lengths from 200mm to 500mm and has a large aperture of F2.8 throughout the entire zoom range. The Sigma APO 200-500mm F2.8/400-1000mm EX DG lens can be used to create amazing image expression with various types of photography such as astrophotography, portraits, wildlife, sports. SLD (Special Low Dispersion) glass and three ELD (Extraordinary Low Dispersion) glass elements provide excellent correction for all type of aberrations. The super multi layer lens coating reduces flare and ghosting.

The lens hood, designed exclusively for this lens, blocks out extraneous light. A 72mm filter can be inserted at the rear of the lens, and a circular polarizing filter can be used in situ thanks to the ingenious internal rotation mechanism. The dedicated Li-ion battery BP-21 is used to power the zooming and AF operation. This battery is built in the lens barrel. For the convenience of the photographer, focusing distances and focal lengths can be viewed on the lens`s built-in LCD panel.

The digital SLR camera market is booming. Compared to last year the DSLR camera sales increased with impressive numbers and it seems the digital SLR camera has become a mass consumer product. New entry level D-SLR cameras with 6 Megapixels surprisingly were welcomed very well by the amateur photographer and it seems that within this segment of the digital camera market the resolution range of 6 - 10 Megapixel fulfils the need of the amateur photographer. Without lenses the digital SLR camera would not be complete and it is for that reason we see a huge number of digital SLR lens introductions appear this year. There are multiple camera manufacturers offering their best own brand solution for its DSLR camera, but there are even more specialized lens manufacturers who offer an impressive number of lens solutions too.
