- Manufacturer's technical data.
Manufacturer description #1
- World's fastest and lightest telephoto lens in its class.
- Sigma SLD (Special Low Dispersion) glass plus Apochromatic and Double-Floating Focus Design for dramatically superior contrast and color correction throughout the focusing range.
- Highly maneuverable for sharp, hand-held long lens images.
- Special dry lubricant and internal focus mechanism assures smooth focusing even in sub-zero temperatures.
- Built-in lens hood and front protective filter.
Manufacturer description #2
Even at ultra-telephoto 300mm, compactness and performance are very stringent. Sigma's APO 300mm uses an apochromat and an inner focusing mechanism for an overall length of just 223mm, in spite of having an aperture of F2.8. Ultra-compact, it weights just 2030g. Also, the use of SLD glass restricts chromatic aberration to extreme limits and obtains excellent images. Single-finger focusing is smooth, fast and precise for manual focusing. Closest focusing distance is 250cm. Equipped with front-end protective glass, it is also suited for outdoor use.
From the editor
Introduced at Photokina 1988.
Notes
- The autofocus will not be available with Nikon D40, D40X, D60, D3000-D3500, D5000-D5600 digital SLR cameras.
- Sigma had to reverse engineer the communication protocol of the Canon EF mount to produce a version of this lens for Canon EOS 35mm film SLR cameras. As a consequence, this lens may not work properly with Canon EOS cameras (both film and digital) due to compatibility issues.
Frequently asked questions
What does the Sigma lens designation "ZEN" mean?
It means that the lens has a ZEN finish. ZEN is an acronym for Zeitgeist ("the spirit of the times"), Enhancement, and Nonglare. This nonreflective urethane resin finish was introduced around 1989 and replaced the old-style, painted satin-black finish. Sigma claimed it to be hard, strong, antichemical, nonslip, antiglare, and scratch-resistant, however, it actually had a tendency to peel off and become sticky as it aged.
