One ED glass element contributes to minimal aberration
Outstanding sharpness and contrast throughout the zoom range
SSM (Super Sonic wave Motor) for fast, quiet autofocus operation
Circular aperture for attractive defocusing
Focus hold and focus range switches offer precision focusing control
The SAL70300G is the smallest and lightest zoom in the current G Lens series,
offering an appealing combination of extended zoom range and handling,
plus image quality that will satisfy the most demanding photo enthusiast or
pro. An ED lens element collaborates with an advanced optical path design
to achieve exceptionally low aberration right out to the maximum 300mm
focal length, so that your telephoto images benefit from impressive clarity
and depth. 300mm is generally considered to be the point at which the
20
"medium" telephoto range ends and the "super" telephoto range begins.
Long focal lengths like this require careful handling to prevent camera shake,

but SteadyShot INSIDE™ image stabilization featured in a series bodies
will help you capture clear, blur-free images in a wider range of handheld
shooting situations than would normally be possible.
