Canon has udpated its EF 70-300mm telephoto zoom, adding a couple of noteworthy features.

The Canon EF 70-300mm f/4.5-5.6 IS II USM lens is driven by the company’s NANO USM technology for “high-speed and near-silent focusing,” which will be welcomed by those who shoot video.

NANO USM combines ring USM (ultrasonic motors) for high-speed autofocus and lead-screw type STM (stepping motor) for very quiet autofocus for video recording.

It will fit full-frame cameras, as well as bodies with APS-C sensors, where it is a 112-480mm full-frame equivalent.

The lens uses 17 elements in 12 groups, including one UD (ultra-low dispersion) element that helps reduce chromatic aberration. Its close-focus distance is 3.9 feet (1.2 meters), and the lens accepts 67mm filters.

The lens uses nine aperture blades.

One new feature is the addition of an LCD panel on the lens barrel. This can display focal length, distance and the amount of camera shake. Obviously, this will be of little while shooting, as you cannot see the display through the viewfinder. To improve visibility of the display, it can be switched between white text on a black background or black text on a white background.

The lens can easily be switched from autofocus with manul adjustment to full-time autofocus.

The Canon EF 70-300mm F/4.5-5.6 IS II USM will be available November 2016 for US$549.99.
