Canon EF 100-400mm f4.5-5.6 L IS USM Lens

The Canon 100-400mm is an L-series super telephoto zoom lens equipped with an Image Stabiliser. The fluorite and Super UD-glass elements largely eliminate secondary spectrum, while the floating system ensures high picture quality at all focal lengths. The Image Stabiliser has two modes and it is compatible with both 1.4x and 2x Extenders (in manual focus on this lens).

Key Features:

• Professional level telephoto zoom
• L-series quality
• Image Stabilizer
• Minimum focusing distance 1.8m
• Fluorite and Super UD lens elements
• Circular aperture diaphragm
• E-TTL II distance metering
• 77mm filter thread

Super zoom
The EF 100-400mm f/4.5-5.6L IS USM is an L-series super telephoto zoom lens, equipped with an Image Stabilizer. Its fluorite and Super UD-glass elements largely eliminate distortions and aberrations. A floating optical system also ensures good picture quality at all focal lengths. The lens is compatible with Extender EF 1.4x II and Extender EF 2x II.

Image Stabilization
The EF 100-400mm f/4.5-5.6L IS USM features a three stop Image Stabilizer (IS), making this an ideal lens for handheld work. Shutter speeds up to three stops slower than normal can be used with no perceptible increase in image blur. Major movement in a particular direction is automatically interpreted as panning and IS is turned off in this plane.

Ultrasonic focusing
A ring-type ultrasonic motor drives autofocus extremely quickly, and in near silence. Excellent holding torque ensures the point of focus is reached accurately, without overshooting. Furthermore, full-time manual override is available, making it possible to adjust focus without leaving AF mode.

Precision optics for high image quality
High contrast, low distortion and good corner-to-corner resolution is evident throughout the zoom range. A virtually circular aperture diaphragm, which is controlled electromagnetically, gives out-of-focus regions a softer, more even feel, and lets in-focus subjects stand out against a blurred background.
