General

The Canon EOS 40D and the Sony Alpha 300 are APS-C DSLRs with optical viewfinders and interchangeable lenses. The 40D arrived in 2007, the Alpha 300 in 2008. Each takes its own lens family, committing you to Canon EF-S or Sony Alpha DT glass.

The Alpha 300 is the smaller and lighter body. It measures 131 x 99 x 75 mm and weighs 632 g, against 146 x 108 x 74 mm and 822 g for the 40D, a 190 g saving in the Sony's favour.

Optics

The 40D is the stronger camera for moving subjects. It shoots at 6.5 fps against the Alpha 300's 3 fps, capturing more frames of a sprinting child or a bird taking off. Its 1/8000 second top shutter speed against 1/4000 helps keep wide-aperture portraits from overexposing in bright sunlight. It also uses a pentaprism viewfinder, where the Sony has a pentamirror.

The Alpha 300 counters with in-body stabilisation, so every lens you mount gains steadier handheld shooting; the 40D offers none. The Sony also reaches 3200 ISO on its standard scale, where the Canon stops at 1600 before expansion. Resolution and focusing are close: both use APS-C sensors of about ten megapixels, CMOS in the Canon and CCD in the Sony, with nine autofocus points each.

Features

The Alpha 300 is the easier camera for low and overhead shots, because its LCD tilts. You can angle the screen for ground-level flower shots or hold the camera above a crowd, composing through live view. The 40D's 3-inch fixed LCD is larger than the Sony's 2.7 inches, which helps when reviewing frames.

The core tools are shared: both bodies offer live view, a built-in flash, support for an external flash unit, and 230,000-dot screens. Neither includes GPS, Wi-Fi, Bluetooth or weather sealing, so location tagging and wireless transfer need other tools.

Storage and Battery

The 40D carries the longer rated battery life, at 800 shots against 730 for the Alpha 300. Each camera uses its own battery pack, the BP-511 in the Canon and the NP-FM500H in the Sony, so spares are brand-specific.

Storage is close to a match. Both record to Compact Flash cards, the 40D accepting Type I or II while the Alpha 300 takes standard Compact Flash. Neither body has a second card slot, and neither charges over USB.

Verdict

Choose the Canon EOS 40D if you photograph action. Its 6.5 fps burst and 1/8000 second shutter give real advantages for sports, wildlife and running children. Its rated battery life is also longer, 800 shots against 730.

Choose the Sony Alpha 300 for everyday handheld shooting. Its in-body stabilisation steadies every Alpha DT lens you mount, and its tilting screen makes live view workable at awkward angles. At 632 g it is also the lighter body to carry. Otherwise, both are capable ten-megapixel DSLRs, and your preferred lens system can decide it.
