Improvements
Changes over the 20D include a bigger 2.5-inch (64 mm) LCD rear screen, improved shutter mechanism rated for 100,000 actuations, improved frame capacity, 1/3 stop increments for sensor speed and an added spot meter. This unit retains the same sensor as its predecessor; all lenses still have an angle of view crop of 1.6. Other changes include a larger 11 frame RAW / 30 frame JPEG buffer, and slightly faster 0.15 second startup. The maximum frame rate is the same (5 frame/s), but a lower-speed 3 frame/s option has been added. The 30D uses the same number of autofocus points as the 20D (nine), but has improved algorithms. The 30D can record in both JPEG and RAW .CR2 files. The 30D's file numbering system holds 9,999 images to one folder, which was introduced with the 5D.
The EOS 30D can also accept the Canon Wireless File Transmitter WFT-E1/E1A for fast file transfer to a remote file server, either through an ethernet cable or a Wi-Fi network. This capability expands the EOS 30D's range of applications to sports and studio set ups where real-time transfer of the images is crucial.
The main competitors for the Canon EOS 30D DSLR are the Nikon D80 and Nikon D200, with the EOS 30D marketed in between the two in terms of cost and features.

Famous quotes containing the word improvements:
“I was interested to see how a pioneer lived on this side of the country. His life is in some respects more adventurous than that of his brother in the West; for he contends with winter as well as the wilderness, and there is a greater interval of time at least between him and the army which is to follow. Here immigration is a tide which may ebb when it has swept away the pines; there it is not a tide, but an inundation, and roads and other improvements come steadily rushing after.”
—Henry David Thoreau (1817–1862)
“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)
“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)
