Along with the Sony Alpha A7II, Sony Japan has also announced the 70-300mm f/4.5-5.6 G SSM II A-mount lens for their Alpha DSLT lineup.
The new Sony G 70-300mm f/4.5-5.6 SSM II (SAL70300G2) promises approximately four times faster dynamic subject tracking performance, and boasts Nano Anti Reflex coating to eliminate flare and ghosts.
The AF motor has also received a notable upgrade to quicken its overall performance, which pairs well with the weather-resistant design to benefit its use in difficult shooting conditions.
