Although for the time being the EOS 500D will sit alongside the 450D in the Canon DSLR line-up there is no doubt that sooner or later it will replace the older model and occupy the spot between the 1000D as and the EOS 50D on its own. The most noticeable new features on the EOS 500D are the higher resolution sensor, the new high-res LCD and the HD video mode but the camera also comes with the latest generation DIGIC imaging processor which brings a few more low-key improvements such as fine-tunable noise reduction and Highlight Tone Priority or a fresher, animated menu design with it.
