Photographer Christopher Frost published another interesting review of an old zoom telephoto lens which is still very much unique in it’s class – the Sigma 300-800mm f/5.6 EX DG HSM also called (unofficially) Sigmonster.
Sigma has been known to create several huge zoom lenses over the years – maybe the most famous one was the humongous 200–500mm f/2.8 EX DG (a.k.a “Sigzilla”) whith its unique green coating and very wide aperture. A different Sigma “monster” zoom lens is the 300-800mm f/5.6 EX DG HSM which Frost looks at in this video.
The 300-800mm f/5.6 EX DG HSM is quite old, it was introduced about 10 years ago, has no image stabilisation system and weighs close to 6kg/13lbs. It is also very expensive at about $7500 (although compared to the price of the new 800mm Nikon/Canon lenses it can be considered a bargain).
According to Frost – there is no chance to shoot with this handheld, build quality is good and is quite sharp (especially if you stop down to f/8), although not on the level of the advanced Canon/Nikon 800mm lenses.
