The Sony SAL-300F28G 300mm f/2.8 APO G SSM Lens is a professional level telephoto lens with wide aperture and fast auto-focus response. Its 35mm-equivalent range of 450mm, a fast f/2.8 aperture and quiet, high-speed SSM (SuperSonic-Wave Motor) auto-focus precision makes it ideal for long-distance sports and wildlife photography.
With a full range of functions geared to the professional photographer, this lens provides sharp, color-free images across the entire film area at all apertures. High-quality multi-coatings and internal baffles increase transmittance and reduce flare to preserve contrast.
The heart of this zoom lens is the finest optical glass reserved for all G-series lenses. This lens uses thirteen finely crafted elements, including three AD (anomalous dispersion) lenses, to virtually eliminate aberrations and curvature of field.
Note: When used with Minolta cameras, AF can only be used with Maxxum 7 or later models (Maxxum 5, 4, 3, etc.). The Maxxum 9 can be updated directly by Minolta to be fully compatible with SSM lenses.
