Canon Introduces The New EOS 50D D-SLR
Canon’s New DIGIC 4 Image Processor Fuels the 15.1 Megapixel Resolution, Expanded ISO Range and Enhanced Noise Reduction of the New EOS 50D Digital SLR
Two Small RAW Formats
In addition to the RAW and JPEG image capture modes that photographers are accustomed to, the EOS 50D Digital SLR camera now offers more manageable resolution settings and file sizes with two sRAW recording formats, sRAW1 and sRAW2. At the sRAW1 setting, resolution is 7.1 megapixels with a file size that is approximately 25 percent smaller than a standard 15.1 megapixel RAW image. With the sRAW2 setting, resolution is 3.8 megapixels at less than half the file size of a standard RAW image, retaining all of the flexibility and creative possibilities associated with full-size, conventional RAW images. The EOS 50D is the first Canon Digital SLR that allows the use of RAW and sRAW settings in Basic Zone as well as Creative Zone shooting modes, even further improving the camera's flexibility.
EOS Integrated Cleaning System
The Self-Cleaning Sensor Unit for the Canon EOS 50D has also been upgraded and now includes a fluorine coating on the low-pass filter for better dust resistance. The Self-Cleaning Sensor Unit uses ultrasonic vibrations to shake dust particles off of the low-pass filter in front of the sensor each time the camera is powered up or shut down. The second part of the system includes a software component where sensor spots are mapped and saved as Dust Delete Data that is attached to the image file for removal during post processing using Canon's DPP software.
