Optics

The EOS 30D is the stronger choice for cropping and for tracking moving subjects. Its 8.2 MP sensor provides more pixels than the D40's 6 MP for cropping into a distant animal. At 5 fps against 2.5 fps, it captures twice as many frames per second. Its 9 autofocus points, against 3 on the D40, give more off-centre places to focus.

The 30D's 1/8000 second top shutter speed is half the exposure time of the D40's 1/4000, useful at wide apertures in bright light. Its native ISO range of 100 to 3200 is wider than the D40's 200 to 1600, though both share the APS-C sensor format. The 30D uses a pentaprism viewfinder, the D40 a pentamirror, and their Canon EF-S and Nikon F DX mounts are separate lens systems.

Features

Both cameras offer a built-in flash and support for external flash units, so fill light for indoor family photos needs no accessory on either body. Each has the same 2.5 inch, 230,000 dot LCD for reviewing shots, with no tilting screen, touch input or live view.

Neither camera has GPS, Wi-Fi or Bluetooth, so neither tags locations or transfers images wirelessly. Neither is weather sealed.

Storage and Battery

Card format is the practical difference. The 30D takes Compact Flash Type I or II cards, while the D40 takes SD and SDHC, so any cards you already own suit only one of the two bodies. Both have a single card slot.

The D40's battery rating is the higher of the two, at 470 shots against 400 for the 30D under their rated test conditions. Each uses its own pack, the EN-EL9 for the D40 and the BP-511A for the 30D, and neither charges over USB, so a separate charger comes with either camera.

Verdict

Choose the Canon EOS 30D if you photograph moving subjects or want room to crop. Its 5 fps shooting, 9 autofocus points and 8.2 MP sensor make it the better tool for sports, wildlife and children playing, where the D40's 2.5 fps and 3 AF points would restrict coverage. The 1/8000 second shutter adds control in bright light.

Choose the Nikon D40 if a light, simple kit matters more. It is 262 g lighter at 522 g, and its 470 shot rating beats the 30D's 400 under test conditions. For travel, family photos and learning photography without heavy gear, the smaller body covers the essentials.
