The EOS Digital Rebel XTi not only sports a newly-refined body with better ergonomics and an improved grip, but it also has some of Canon's most advanced improvements in dust reduction. No matter how careful photographers may be to change lenses in dust free areas and to keep their equipment as clean as possible, dust often ends up on their cameras' sensors, creating distracting spots on recorded images. The Digital Rebel XTi's integrated hardware and software solutions make trouble with dust a thing of the past. The Digital Rebel XTi is the first digital EOS SLR camera to feature this important technology: by ensuring the sensor is free of dust and debris, the camera delivers a cleaner image.
Self Cleaning Sensor Unit
To combat against stray dust that enters the camera and adheres to the image sensor during a lens change, the Digital Rebel XTi features an all-new, Canon-designed Self Cleaning Sensor Unit. The low pass filter cleans itself automatically with ultrasonic vibrations, removing dust from the sensor assembly.
Dust Delete Data Detection
Dust that has been missed by the Integrated Self Cleaning Sensor Unit can also be erased with software included in Digital Photo Professional (DPP) Version 2.2. The Digital Rebel XTi's imaging sensor is able to single out the dust particles on its surface, then plots out their location coordinates within the image. This data is transmitted along with the image, whether JPEG or RAW, and can be either manually or automatically erased in Canon's DPP 2.2. This added software option ensures the cleanest possible image, perfect for printing or archiving.
