Nikon’s flagship DX-format DSLR adds D-Movie capabilities and dual card slots to the feature set of the D300.Depending on how you rate the addition of video capture and dual card slots, Nikon’s D300S can be rated as either a major or minor upgrade to the D300. Aside from these features, little has changed from the earlier model. The sensor is the same DX-format 12.3 megapixel (effective) chip and both models include Nikon’s latest EXPEED image processor which is the same as in the D90 (the first DSLR to offer HD video recording).
A lightweight, easy-to-operate DSLR with high resolution for creative photography.Canon’s EOS 550D slips into the company’s line-up between the EOS 500D and the EOS 50D and offers higher resolution than both models without displacing either. It boasts the same 18-megapizel sensor as the EOS 7D but has only one DiG!C 4 processor. A key feature is the addition of a new, high-resolution 3:2 aspect ratio LCD monitor and a redesigned interface. Video capabilities have also been extended to support Full HD movie recording at a range of different frame rates.
