Canon EOS 50D Black SLR Digital Camera Body Only
This camera features an APS-C sized 15.1-megapixel CMOS sensor and DIGIC 4 Image Processor for color reproduction and writes times to UDMA cards. It also features a 3.0-inch Clear View LCD 920,000 dots monitor, recording up to 4752 x 3168 pixels with full 14-bit A/D conversion.
The sensor is designed to work with Canon’s EF and EF-S lenses with a conversion factor of 1.6x. It can shoot up to 6.3 fps, in bursts of up to 90 JPEGs using an UDMA CF card, 60 JPEGs using a CF card consecutively or 16 RAW files. The model can also capture images to Compact Flash Type I or II memory cards. The camera uses the Canon EF lenses including EF-S lenses and its image sensor size is 22.3 x 14.9mm. The camera type is identified as the digital single-lens reflex AF or AE camera with built-in flash. A RGB primary color filter is implemented with low-pass filter position in front of CMOS sensor. The recording system follows design rule for camera file system 2.0.The model’s dimensions are 5.7x 4.2 x 2.9 inches and its body only weighs 25.7 ounces.
The model uses 35-zone full-aperture metering which is evaluative, partial 9 percent of viewfinder at center and spot 3.8 percent of viewfinder at center with center-weighted average as its metering criteria.
ISO speed is automatically set at ISO 100 to 6400 (in 1/3-stop or 1-stop increments); basic zone modes at ISO 100 to 3200 and extension settable at ISO 12800 as well as high-tone priority settable at ISO 200 to 1600.With a maximum ISO rating of 12800 combined with a 4-level High ISO speed noise reduction function, the camera record all sorts of images.
The EOS 50D has a high-precision 9-point wide area AF that uses cross-type points at f-stops of f/5.6 or faster, enabling the camera to focus in difficult lighting situations. AF sensitivity is an EV-0.5 to EV18. Adding to this, the EOS 50D incorporates a diagonally mounted cross-type sensor that is sensitive to both vertical and horizontal lines at f/2.8 for operations occurring in dim light. The EOS 50D has a number of focus modes, including One-Shot AF, AI Focus AF and AI Servo AF.
Canon lenses also uses several type of optical technologies such as Aspherical, ultra-low dispersion or fluorite elements that are featured in the L-series lenses.
The EOS 50D features Canon’s Live View shooting including Quick mode, Live mode and Face Detection Live mode. Users can zoom in and navigate the composition 5x or 10x normal size, enabling critical focus. There are 2 overlay grid options for lining up vertical and horizontal lines. In the studio, the camera can be controlled remotely with Live View Function when the camera is connected to a computer through a USB cable, or wirelessly if the optional Wireless File Transmitter WFT-E3A is used.
Next to this, Canon’s Lens Peripheral Illumination setting takes into account any light falloff in the corners of the frame and corrects it for all exposed image. Correction data are detected automatically on a number of Canon EF lenses and can be entered manually through included the Canon EOS Utility software.
The EOS 50D’s Self Cleaning Sensor Unit eliminates stray dust that enters the camera when changing a lens or when out in the field. The sensor’s IR-cut/Low-pass filter cleans itself automatically with ultrasonic vibrations every time the camera is turned on or off and features a fluorine coating to minimize dust adhesion. Dust missed by the cleaning unit is captured by Canon’s Dust Delete Data Detection software.
Dust that may still remain on the front of the sensor can also be erased with software included in Digital Photo Professional (DPP) Version 3.3 or later software. A simple test shot of a plain, white object can be taken, using a menu setting. This Dust Delete Data image is analyzed in-camera, and the location and size of any remaining dust is added to any subsequent pictures taken. This data is transmitted along with the image, whether JPEG or RAW, and can be either manually or automatically erased in Canon’s DPP software.
In addition, the EOS 50D includes a new HDMI (High Definition Multimedia Interface) output device that enables High Definition display of photographs on any HDTV with HDMI ports. Resolution is set to match the TV connected and images are displayed in a full-frame 3:2 ratio with blacked out bars to the left and right of the image.
Lastly, Canon’s Optical Image Stabilizer technology is featured in select lenses to minimize the effect of camera shake. Auto Lighting Optimizer that corrects brightness and contrast automatically and Peripheral Illumination Correction for up to 40 EF lenses are featured too.
