telephoto end of the lens and when vibrations are more severe. It also features
increased sensitivity to low frequency vibration, such as the rocking of a boat.
Minute vibration gyros detect camera movement caused by hand shake. These signals –
at 8,000 per second, twice the speed of signals in conventional IS – are processed to
discriminate between hand shake and intentional camera movements. The IS unit
moves one of the lens elements accordingly to re-align the light rays and cancel out the
effects of shake.
For improved accuracy and responsiveness, the moving lens element is supported on
tiny ceramic spheres. In addition to minimising friction, ceramic spheres avoid some of
the problems that can affect metal systems, such as thermal expansion and
magnetism.
Enhanced i-Contrast
The improved Intelligent Contrast Correction technology (i-Contrast) now includes
dynamic range expansion. Available in either shooting or playback mode, i-Contrast
function analyses the exposure, dynamic range and other image characteristics of a
shot, then adaptively increases the gain in dark areas – to produce heightened detail in
darker regions, without blowing out correctly-exposed parts of the image. The noise
reduction function of DIGIC 4 ensures minimal noise in adjusted areas.
Smart Auto Mode with Scene Detection Technology
Available in Smart Auto mode, Canon’s Scene Detection Technology analyses the
shooting scene by taking into account subject brightness, contrast, distance, overall
hue and now face movement. The optimum settings are then automatically selected for
each scene from a choice of 22 possible variables. A colour icon indicating the type of
scene detected – and the lighting conditions of the scene - is shown on the LCD
monitor.
Smart Auto mode gives users the reassurance that the camera will take care of settings
and deliver great results - even when shooting moving subjects, backlit scenes, night
shots, sunsets, and shots taken at very close range.
Smart Auto mode also increases image dynamic range to reduce highlight blow-out
when shooting bright scenes, reduces dynamic range to improve contrast in low-
contrast scenes, and automatically enhances blue saturation for blue skies.
