The 70-300mm f/4.5-5.6G Telephoto Zoom Lens from Sony is a G-series Sony Alpha telephoto zoom lens that uses supersonic-wave motor (SSM) technology for quieter, smoother AF operation. It is constructed of 16 elements in 11 groups, as well as its dual Extra-low Dispersion (ED) glass, which all help to deliver sharp, clear photos throughout the zoom range.
It has a minimum focusing distance of 4.0' and a front-end filter diameter of 62mm. High-quality multi-coatings increase transmittance and reduce flare to preserve contrast, while its 0.25x maximum magnification and optional teleconverter compatibility give it increased zoom and versatility.
Aperture Range: f/4.5-29
In addition to the zoom range, the aperture varies along with the focal length: with f/4.5 to 5.6 at the wide end, and up to f/22 to 29 throughout the zoom range.
For Full Frame A-Mount and APS-C DSLRs
For Sony A-Mount full frame and A-mount APS-C sensor cameras. The lens covers a 4.3x zoom range from 70mm to 300mm telephoto on full frame, and provides the 35mm focal length equivalent of 105-450mm on APS-C cameras.
2x Extra-Low Dispersion (ED) Glass
To reduce chromatic aberrations, most noticeable when zoomed all the way in, the extra-low dispersion glass corrects for certain wavelengths of light - producing sharper images with truer colors.
Super Sonic Wave Motor (SSM)
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.
In-Camera Image Stabilization
Because Sony's Alpha DSLR cameras have image stabilization built-in, the lenses attached to them don't require the added bulk. This leaves the lens lighter and more compact without the need for the added mechanics.
Minimum Focus Distance: 4.0'
With the ability to focus as closely as 4 feet (1.2 m), this telephoto lens also lets you move in for dramatic shots of people, natural subjects and close-up details.
Filter Diameter: 62mm
The 62mm from filter thread does not rotate, allowing rotating polarizing filters to be used.
Focus Hold Button
This lens is made with a Focus Mode switch and Focus Hold button, which offer better focus control whenever you need it.
