L-series quality
The L-series is Canon's flagship professional lens range, representing the best in precision-designed EF optics. L-series lenses combine superior performance with superlative handling, and are resistant to dust and moisture.
Large f/2 aperture
A large maximum aperture of f/2 provides outstanding speed for shooting in low light conditions, without the need for flash. The large aperture also provides fine control over depth of field for compelling portrait photography.
Five-Stop Image Stabilizer
Canon’s five-stop compensation Image Stabilizer technology allows the use of shutter speeds up to five times slower with no perceptible increase in image blur. Automatic panning detection automatically turns off the Image Stabilizer in either the horizontal or vertical direction when following moving subjects. Tripod detection automatically switches off IS when the camera is supported.
Super Spectra coating
Super Spectra coatings ensure accurate colour balance and enhance contrast. They also reduce flare and ghosting – a common problem caused by light bouncing off a camera's sensor.
Fluorite and UD elements
For optimum visual performance, the lens incorporates Fluorite and UD (ultra-low dispersion) elements to minimise chromatic aberrations. The result is crisp, high contrast and exceptional image quality throughout the frame.
Smooth background blur
A virtually circular aperture diaphragm gives out of focus regions a softer, more uniform feel. Sharp foreground objects stand out against a smooth blurred background.
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.
