Sigma 300-800mm f/5.6 EX DG HSM lens covers the telephoto range from 300mm to the ultra-telephoto range up to 800mm. The lens is providing a constant fast aperture and is weighing in at over 13 pounds.
This lens has two ELD (Extraordinary Low Dispersion) glass elements in the front lens group for excellent correction of chromatic aberration. The HSM (Hyper Sonic Motor) for fast and silent auto focus with full-time manual focus capability. By adding 1.4x EX teleconverter you can use this lens as 420-1120mm f/8 MF, or if that’s not long enough, you can stack your 2x EX teleconverter for 600-1600mm f/11 MF. Now that’s HUGE!
REVIEWS & SAMPLES (last update 06.02.06)
Ephotozine reviewed the Sigma 300-800mm f/5.6 EX DG HSM and wrote:
“The optical qualities of the lens make it worth carrying the weight along with you. It is sharp throughout the range, has excellent contrast and good neutral colour rendition. With a constant aperture of f/5.6 throughout the focal lengths and excellent performance wide open there is very little to criticise. Distortion is almost immeasurable with figures of less than a half of one percent at both ends of the zoom. Chromatic aberrations are also non existent until refraction kicks in at smaller apertures and even then they are well controlled.”

Shutterbug reviewed the Sigma 300-800mm f/5.6 EX DG HSM and wrote:
” Construction wise, the lens incorporates all of the features that fall into the top of the line Sigma lens category. First off it’s an “EX” lens which means that this Sigma is EX-finished denoting a special exterior finish that is both very durable and handsome in appearance. Without you, the reader, personally holding the lens, it almost feels like a coating of velvet has been applied to all exterior surfaces of the lens barrel and hood. Fit and finish was never under debate and both the zoom and focus ring are coated with a ribbed, non slip rubber coating. For accents, there is a gold ring about the front lens element and all markings and numbers are large and enhanced with brilliant white filler.

“If you’re looking for 500 mm to 1000 mm and beyond reach, the 500 f/4 L IS is lighter (hence can be hand held) and more compact, 1 stop brighter and most probably a bit sharper at 500 mm, has IS, faster AF and weather-sealing.But if you value the framing flexibility of zoom while still retaining near-prime sharpness, and can live without IS, the Sigmonster is a worthy alternative to the similarly weighing 600 f/4 L IS.
