The 50D is remarkably similar to the 40D in terms of performance, looks and features, but there are other big change is the inclusion of a new, high-resolution LCD screen. 920,000 dots mean that it can convey 640 x 480 RGB pixels, making it effectively a VGA standard monitor. Three anti-reflection layers built into the screen do their best to keep it useable in bright conditions.
