Features for Canon EF 100mm f/2 USM
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."
