The SAL-70300G 70-300mm f/4.5-5.6G SSM Autofocus Lens is a medium-to-long telephoto lens that employs supersonic-wave motor (SSM) technology for quieter, smoother AF operation. This G-Series zoom lens covers a broad range of frequent telephoto shooting situations. The equivalent focal length in 35mm terms for this lens is 105-450mm.
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 increase transmittance and reduce flare to preserve contrast.
SSM (Super Sonic wave Motor)
A built-in lens motor for faster automatic focusing with high torque at low speed, quick start/stop response, and quiet, smooth operation.
ED (Extra-low Dispersion) Glass
Four precision ED Glass lenses correct chromatic aberrations and deliver visually accurate results even at full telephoto zoom extension.
Focus-Range LimitCircular Aperture
For creative control and image preview, a focus hold button conveniently located on the lens barrel lets you firmly lock in focus, and a focus range limiter can be set to speed auto-focus response.
Because the aperture blades form a near circle at the wide openings used for low-light shots, spot-light sources have a pleasing circular defocused effect.
