The Sony A 70-300mm f/4.5-5.6 G SSM II is a Sony A-mount telephoto zoom lens and update to the Sony 70-300mm f/4.5-5.6G SSM. Key features include:

What’s New? With this latest release, Sony has improved the autofocus tracking algorithm and Super Sonic wave Motor for performance that’s up to four times faster than the original version.

Telephoto Zoom. The extended zoom range is a great option for wildlife and outdoor-sports shooting. The somewhat slower variable f/4.5-5.6 aperture will limit its usefulness in low light, though.

SSM Autofocus Motor. This in-lens autofocus motor offers very fast, nearly silent performance.

Build. The weather-sealed lens features a single extra-low dispersion element in its eleven-group/sixteen-element design, maximizing image quality and contrast while reducing chromatic aberrations. The non-rotating front element makes it fully compatible with circular polarizers and variable ND filters.
