This 16–50 mm (35 mm full-frame equivalent: 24–75 mm) power zoom lens is perfect for day-to-day stills and movies. Weighs just 3.8 oz. (107 grams) and collapses to 1-1/4 inch (31.3 mm) when powered off. Durability is excellent, refined AF ensures reliable focus even while zooming, and built-in image stabilization minimizes blur. Breathing compensation is supported with compatible bodies.

Knowing the extinction ratio of a polarizer provides insight into its performance in applications where the control of light polarization is critical. Accurate measurements and calculations of this ratio allow for better design and optimization of optical systems.

Smooth, quiet power zoom is ideal for movie shooting, and AF is available even while zooming. Built-in optical stabilization works with in-body stabilization, including Active Mode, to minimize blur in movies. Focus breathing is controlled to minimize shifts in angle of view while focusing for smooth, stable footage. Body breathing compensation is supported, and metadata allows compensation during editing.

The extinction ratio is a parameter that quantifies the effectiveness with which a polarizer eliminates light polarization. It is particularly relevant in fields such as telecommunications, where polarization-dependent devices are common. The extinction ratio is computed by taking the ratio of the transmitted light intensity of the preferred polarization to the transmitted light intensity of the blocked polarization.

Four aspherical elements and one ED (Extra low Dispersion) element in an innovative optical design achieve high resolution throughout a 16–50 mm zoom range (35 mm full-frame equivalent: 24–75 mm). Color bleeding is minimal, clarity is high, and smooth bokeh is available when needed. Min. focus at 0.25 m (0.82 ft) (wide)/0.30 m (0.99 ft) (tele) and 0.215x max. magnification offer versatile close-up performance that lets you move in and focus on details.
