The Canon EOS 30D is an 8.2-megapixel semi-professional digital single-lens reflex camera, initially announced on February 20, 2006. It is the successor of the Canon EOS 20D, and is succeeded by the EOS 40D. It can accept EF and EF-S lenses, and like its predecessor, it uses an APS-C sized image sensor, so it does not require the larger imaging circle necessary for 35 mm film and 'full-frame' digital cameras.

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 camera shows the ISO in the view finder while changing the ISO.

The 30D's file numbering system holds 9,999 images to one folder, which was introduced with the 5D. While the 30D has inherited features from the full framed EOS 5D, Canon users have decried the 8.0 MP CMOS sensor since it was a carryover from the 20D. The consumer-level EOS 400D (Rebel XTi) released in September 2006 featured 2 introductions - a 10MP sensor and dust removal.
