Improvements
Changes over the 40D include a higher-resolution sensor (15.1 megapixel instead of 10.1 megapixel).
The ISO goes up to 3200 in standard mode, and can be increased to 12800 through the use of a custom function. The burst rate is the same as on the 40D, 6.3 frames per second, though the 40D was advertised as 6.5.
The camera uses Canon's DIGIC 4 image processor. The processor delivers more responsive operation, improved color rendition and near-instant start-up time. A new sensor cleaning system has also been introduced. The camera can also use the Canon Wireless File Transmitter WFT-E3/E3A.
The 50D has a 3" screen – the same size as the 40D – but the resolution is 640×480 pixels, which allows it to show more image detail than any of Canon's previous 3" LCD displays. The 50D features two new Autofocus Modes in Liveview and an HDMI port.
The 50D is offered as a body only or in a package with a new EF-S 18-200mm f/3.5-5.6 IS lens or EF 28–135 f/3.5-5.6 IS USM lens.

Famous quotes containing the word improvements:
“The improvements of ages have had but little influence on the essential laws of man’s existence: as our skeletons, probably, are not to be distinguished from those of our ancestors.”
—Henry David Thoreau (1817–1862)
“... these great improvements of modern times are blessings or curses on us, just in the same ratio as the mental, moral, and religious rule over the animal; or the animal propensities of our nature predominate over the intellectual and moral. The spider elaborates poison from the same flower, in which the bee finds materials out of which she manufactures honey.”
—Harriot K. Hunt (1805–1875)
“A country whose buildings are of wood, can never increase in its improvements to any considerable degree.... Whereas when buildings are of durable materials, every new edifice is an actual and permanent acquisition to the state, adding to its value as well as to its ornament.”
—Thomas Jefferson (1743–1826)
