Three years ago Olympus was first to market with a solution: its sensor vibration technology, which knocked dust off the sensor. Sony's recently introduced Alpha digital SLR possesses a similar mechanism.
Now Canon is jumping into the fray with the most comprehensive weaponry yet: the EOS Integrated Cleaning System, introduced in the EOS Digital Rebel XTi in September. Canon redesigned the low-pass filter to separate it into two physical parts (to keep dust away from the sensor), added vibration technology to shake dust from the sensor, and inserted a feature that maps any remaining particles to remove them with software.
