The Canon EOS 450D incorporates a number of high-end functions and technology found in Canon's professional SLR models, including an improved autofocus sensor, enhanced 14-bit A/D conversion, and an advanced Live View function. Plus the proprietary DIGIC III image processor ensures that the fine details and natural colors of the images are optimally recorded, and also manages the camera's efficient energy consumption and high-speed signal processing performance.
The 12.2 megapixel APS-C size CMOS sensor employs large microlenses over each pixel to reduce noise and enhance sensitivity up to ISO 1600, while the 14-bit Analog-to-Digital (A/D) conversion process means the 450D camera records up to 16,384 colors per channel and allows the camera to produce images with finer and more accurate gradations of tones and colors. The camera also incorporates the Highlight Tone Priority and High-ISO Noise Reduction functions (previously found only on Canon's Professional Digital SLRs) and the camera is equipped with Canon's Auto Lighting Optimizer technology, which corrects image brightness and contrast automatically to prevent underexposure with backlit scenes.
The EOS 450D is capable of continuously capturing 3.5 frames per second for bursts of up to 53 images. The faster frame rates and finer focusing capabilities of the 450D together with its impressive image burst rate will help photo enthusiasts capture split second action at just the right moment. Furthermore, the camera is equipped with a host of useful creative controls, including shutter speeds ranging from 1/4000 sec. to 30 sec. plus Bulb, a choice of four metering patterns including 4% spot metering, a wide range of exposure modes from fully automatic to fully manual, depth of field preview, mirror lock and much more.
The large, 3-inch, 230,000 pixel LCD monitor makes it easier for users to review images and scroll through the menus, and also features a broadened color gamut and a wide viewing perspective in all directions. Furthermore the EOS 450D camera features Live View - which allows users to frame shots through the LCD screen rather than the viewfinder - this is particularly useful when shooting at odd angles or in situations when looking through the viewfinder is impractical.
The 450D DSLR utilizes Canon's EOS Integrated Cleaning system. This involves a Self-Cleaning Sensor Unit that shakes dust particles off of the low-pass filter in front of the sensor, along with post processing with the supplied Digital Photo Professional software. Here the camera maps any spots that may remain on the sensor and subsequently subtracting dust spots from the final image during post processing.
