Sigma 300-800mm f/5.6 EX DG HSM APO Reviews

ShutterBug reviews the Sigma 300-800mm f/5.6 EX DG HSM APO and writes;
“Images were bright and no matter what zoom setting I used there was no darkness in the finder. As an added plus, the lens focuses down to 20 ft, which is really impressive especially at 800mm.”
rating: N/A

Luminous-landscape reviews the Sigma 300-800mm f/5.6 EX DG HSM APO and writes;
“Image quality is superb. The Sigma HSM focusing motor is the match of Canon’s Ultrasonic USM motor at f5.6. The Canon system is faster at f4, but that’s always the case. A larger maximum aperture will allow for faster focusing speeds. Focusing accuracy is also, at least in my sample very, very good. I almost never override and use manual focus, and I’m a stickler for focus accuracy.”

Ephotozine reviews the Sigma 300-800mm f/5.6 EX DG HSM APO and writes;
“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. The only nit-pick I could come up with, and that is not really a quality problem is the close focus distance of six metres..”

Photodo reviews the Sigma 300-800mm f/5.6 EX DG HSM APO and writes;
“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.”

The SIGMONSTER | Rating: ★★★★★
“this lens has fantastic image quality — very sharp, excellent contrast. When I say sharp, I am talking L-series sharp, even wide open. The HSM focus speed is fast, perhaps slightly slower than Canon’s USM but not appreciably so..” – by Michael A. Hays

Sigma 300-800mm f/5.6 EX DG HSM APO Specifications

The Sigma APO 300-800mm f5.6 EX DG HSM Lens for Nikon Digital SLR Cameras provides a constant fast maximum aperture throughout the entire zoom range and is optimized for digital SLR cameras. By continuously varying the angle of view from 8.2 degrees to 3.1 degrees, the lens takes a lot of the footwork out of picture composition.

The multi-layer lens coating and lens design reduce flare and ghosting, which is a common problem with digital cameras, and it also creates an optimum color balance. Two Extra Low Dispersion (ELD) glass elements in the front lens elements reduce chromatic aberration to a minimum and also ensure sharp, quality images of high contrast. The lens’ Hyper Sonic Motor (HSM) provides silent, high-speed and precise auto-focusing with full time manual focus override. The lens also features a drop-in 46 millimeter filter holder in the rear part of the lens barrel, which can be rotated to facilitate the use of filters, including a polarizing filter. Since focusing and zooming do not change its overall length, this lens is easy to hold and use. In addition, since the front of the lens does not rotate, a circular polarizing filter can be easily attached and used. This lens accepts both 1.4x and 2x APO EX Tele-Converters (sold separately).
