General

The Canon EOS 30D and the Nikon D40X are APS-C DSLRs from the mid-2000s, each built around an optical viewfinder and interchangeable lenses. The 30D, announced in 2006, is the larger and heavier body at 144 x 106 x 74 mm and 784 g, against 124 x 94 x 64 mm and 522 g for the 2007 D40X. That size and weight gap favours the D40X for carrying on everyday trips, while the 30D offers a bigger body to hold.

Optics

For moving subjects, the Canon EOS 30D is the stronger choice. It shoots at 5 fps against the D40X's 3 fps, so a burst catches more of a fast sequence. Its 9 autofocus points against 3 give you more placement choices across the frame, and its 1/8000 second top speed allows shorter exposures than the D40X's 1/4000. The 30D's viewfinder uses a pentaprism, while the D40X uses a pentamirror.

The D40X answers with more pixels for cropping and larger prints, 10 MP against 8.2 MP. A useful similarity is the APS-C sensor format, so both work with the same class of wide-angle and telephoto reach. The 30D reaches 3200 ISO natively against 1600 ISO, though both extend to 3200. Base sensitivity is 100 ISO on each, and neither offers in-body stabilisation. Lens choice follows the mounts: Canon EF-S or Nikon F DX.

Features

Both cameras give you the same fixed 2.5-inch LCD with 230,000 dots, so reviewing photos and changing settings looks the same on either body. Neither offers live view, so you compose through the optical viewfinder and use the screen for playback only.

Flash support is shared as well. Each camera has a built-in flash and supports external flash units, covering fill light and dedicated flash work. Neither body offers weather sealing, a tilting screen, touch control, Wi-Fi, Bluetooth or GPS.

Storage and Battery

The Nikon D40X has the higher rated battery life, at 520 shots for its EN-EL9 pack against 400 for the 30D's BP-511A.

The two cameras take different memory card formats, Compact Flash Type I or II in the 30D and SD or SDHC in the D40X. Any spare cards you already own therefore steer the choice. Each camera has a single card slot, and neither charges over USB.

Verdict

Choose the Canon EOS 30D for action photography. Its 5 fps burst, 9 autofocus points and 1/8000 second shutter speed directly serve sports and wildlife. Choose the Nikon D40X for travel and everyday shooting. It weighs less, offers 10 MP instead of 8.2 for more cropping room, and carries a 520-shot battery rating against 400. Anyone already owning Canon EF-S or Nikon F DX lenses should let that system decide, since neither body accepts the other's lenses.
