Fast and wide
The lens' large maximum aperture of f/1.8 ensures photographers
can use fast shutter speeds in a variety of different lighting
conditions, and blur backgrounds by controlling depth of field. An
aspherical lens element corrects distortion and ensures the image
is sharp across the frame.
When fitted to EOS cameras with APS-C sized sensors, the EF 28mm
f/1.8 USM offers a field of view equivalent to a 45mm lens on a
full-frame camera, making this an ideal fast-aperture standard
lens.
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 EF 28mm f/1.8 USM passes distance information back to a
compatible EOS camera's E-TTL II flash system to ensure optimal
flash metering.
