Canon EF 70-200mm f/4L USM Lens

Canon's EF 70-200mm f/4L USM Lens is a compact, yet powerful telephoto zoom lens in Canon's L Series of lenses. It offers a 35mm equivalent focal length of 112-320mm when working on a APS-C sized sensor.  An ideal choice for such applications as sports photography and portraiture, it is fully compatible with the Extender EF 1.4x II and 2x II teleconverters (requires f/8 AF sensitivity with EF 2x II). 

Canon L Series

The L Series denotes Canon's professional line of lenses.  Though used extensively by non-professionals, these lens have been engineered to the highest of standards. These luxury lenses incorporate such advanced optical advantages as Super Low Dispersion Glass, Ultra-Low Dispersion Glass, flourite elements and aspherical design elements.  All of these combine to produce reliably incredible images.

Anti-Reflective Coating

The Canon anti-reflective coating is an optical design feature which ensures superior clarity and image brilliance, even in poor or unfavorable lighting conditions. Canon applies the anti-reflective coating through a special process, layering the lens surface in order to substantially reduce unwanted flare or ghosting.  This process helps to ensure incredibly rich image contrast and true color fidelity. 

Range Limiter

The Focus Range Limiter enables you to set a limit on the focusing range, saving you time rather than letting the lens "hunt" through the entirety of the range. In macro lenses this limit can be either the near of the far range

Fluorine Coating

Canon L Series lenses feature a fluorine coating on the front and rear surfaces. This coating helps to greatly reduce smears, smudges or fingerprints ensuring that you will always take impeccable images.

Manual Focus

Manual focusing means you have all the control at the end of your fingers. Canon lenses feature a specially designed ergonomic construction that is noticeable at first touch. The large rotation angle of this lens guarantees precise focusing.  The mechanism moves super smoothly and without extra play, furthering the intuitive interaction along the focal plane.  

Ultra Sonic Motor (USM)

Canon's USM lenses employ a motor powered by ultrasonic waves that produce a quiet, yet high-speed AutoFocus. You can enjoy high performance with low noise in a variety of shooting situations.

Ultra Low Dispersion Glass (UD)

Canon's Low Dispersion technology is engineered to reduce chromatic aberrations, eliminating the tendency of light of different colors to focus to different points at the image plane. This means your images will come out crisp and clear, with less of a chance of defracting light into an unwanted rainbow of colors. Take shots exactly like you want, without any flare-up or blurring.

Advanced Aperture Design

The circular aperture produces a natural background blur. With Canon lenses you can create stunning Bokeh effects, thanks to the finely tuned features and advanced optical design. By keeping the background intentionally blurred, additional focus is created on the subject of an image. The uniquely engineered diaphragm blades of this lens, along with the virtually circular aperture, deliver stunning renditions of highlights the back and foreground.
