Canon EF 100mm f/2 USM

Detailed Features

• Long focal length and compact size

  The EF 100mm f/2 USM has a large maximum aperture, but is still relatively compact. The 100mm focal length lets photographers maintain a comfortable working distance from their subjects, and also helps to compress perspective. Sharp, crisp pictures are obtained at all apertures throughout the range.

• Large f/2 aperture

  A large maximum aperture of f/2 provides outstanding speed for low-light shooting, without the need for flash. Shooting at such wide apertures also throws the background out of focus, placing more emphasis on the subject.

• 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.

• 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.

• Integration with E-TTL II flash metering

  The lens passes distance information back to a compatible EOS camera's E-TTL II flash system to ensure optimal flash metering."
