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 α 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.
