Compact Design, All-Around Versatility - This superb 70-300mm zoom lens is an excellent choice for a wide range medium to long-distance telephoto applications and its lightweight design lets you leave it on-camera or carry it easily as an accessory lens for special purposes (35mm equivalent: 105-450mm). Superb Optical Performance - Sony's G-Series lenses are designed for maximum descriptive power, maintaining excellent peripheral light characteristics and minimizing contrast drop-off even at the edges of the frame. Short Minimum Focusing Distance - With the ability to focus as closely as 4 feet (1.2m), this telephoto lens also lets you move in for dramatic shots of people, natural subjects and close-up details. In-Camera Image Stabilization - A major reason for its compact, lightweight design is the benefit of Super SteadyShot in-camera image stabilization, built into every Sony 945 system DSLR and enabling accessory lenses to eliminate the extra weight and expense of in-lens stabilization mechanisms. SSM (Super Sonic wave Motor) - Designed for fast, smooth, silent automatic focusing, this unique technology achieves high torque at low speed with rapid start/stop response. It operates through the ability of a piezoelectric device to reshape itself quickly when voltage is applied. Focus Hold Button - 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. Smooth Manual Focusing - An easy-grip focus ring on the lens barrel gives you a solid hands-on feel in manual focusing. Multi-Element Design with Internal Focusing - The SAL-70300G is designed with 16 lens elements in 11 groups, with internal focusing so the balance of your camera never changes. ED (Extra-low Dispersion) Glass - Because light of different wavelength (or color) bends at different angles when it passes through a lens, ED (Extra-low Dispersion) Glass is used to eliminate chromatic aberration by correcting certain wavelengths of light for sharp, clear images with well defined colors. Circular Aperture - 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.
