The Canon EOS 50D is a 15.1-megapixel digital single-lens reflex camera. It is part of the Canon EOS line of cameras, succeeding the EOS 40D and preceding the EOS 60D.
Canon announced the camera on 26 August 2008. The camera was released on 6 October 2008.
The 50D has many similar characteristics to its predecessor, the 40D. This includes various shooting modes, the ability to change ISO and white balance, a pop-up flash unit, and an LCD screen. The LCD screen is the same size (3.0") as the 40D but has a higher resolution (640 × 480 pixel or 307,200 pixels) than any previous model. It is also the final Canon xxD to use a CompactFlash or Microdrive for memory storage, along with the BP-511 series battery.
The 50D has a higher pixel count (15.1 megapixels), hence higher shooting resolutions, than its predecessor and, like the 40D, has a 14-bit RAW format.
The camera has Live View, which allows photographers to use the LCD screen as the viewfinder. Because the sensor mirror needs to be in the locked position (see Live preview), shutter noise is reduced in this mode.
