Description

Product Highlights: Fluorite & UD Lens Elements EF Mount L-Series Lens Aperture?s Range is f/4-32 Ultrasonic Autofocus Motor 67mm Filter Thread Diameter Permanent Manual Focus Override Internal Zooming & Focusing Focus Range Limiter Compatible with 1.4x & 2x Extenders Minimum Focus Distance: 3.9? Maintaining the outstanding performance at max aperture of the much superior f/2.8L but in a compact size, the EF 70-200mm f/4L USM Lens from Canon is a professional zoom telephoto appropriate for a wide range of applications from portraiture to sports. It is fully well-suited with the Extender EF 1.4x II and 2x II tele-converters (requires f/8 AF sensitivity with EF 2x II). Similar to every autofocus Canon ?L? lens, the EF 70-200mm f/4LUSM produces optical performance equivalent to related fixed focal length lenses, having quiet, high-speed ultrasonic (USM) focusing and permanent manual focus override capability. A focus range restraining option also allows rapid autofocus rates. Distortions and aberrations are extremely tiny for a lens of such capacity. This lens joins 1 artificial fluorite element with two UD (Ultra-low Dispersion) elements which are helpful in achieving images free of secondary spectrum aberrations that are often the curse of consumer-grade telephoto zooms. It is lighten enough to not require a tripod collar (86 percent lighter than EF 70-200mm f/2.8L), but for handling functions there is an optional tripod collar. The min distance of focusing is 3.9? (1.2m) in its entire range of focal lengths, and it accepts 67mm screw-in filters. Note: This lens doesn?t have seals for moisture and dust resistance. An autofocus telephoto zoom lens for both film and digital cameras with invariable f/4 maximum aperture performance an ultrasonic autofocus motor gives quiet, quick autofocus action. Permanent manual focus override lets accurate manual focus at every time, even in AF mode. 2 focus distance ranges allow you to regulate the autofocus to fit your needs and cut down AF speeds. The ranges are 3.9? to infinity for nearer subjects and 9.8? to infinity. Inner zooming and focusing means that the lens face element does not revolve Uses one fluorite and two UD (Ultra-low Dispersion) elements to control secondary spectrum aberrations Uses 67mm size filters and an elective tripod collar (A-IIW) is compatible as are the 1.4x II and 2.0x II extenders
