Canon’s EOS 450D – or Digital Rebel XSi as it’s known in North America – is the company’s latest DSLR and the successor to the hugely popular EOS 400D / Rebel XTi. Announced towards the end of January 2008, just a few days before the annual PMA show, the 450D / XSi features a number of key improvements over its predecessor – some predictable, others less so.
In the predictable category is the inevitable increase in resolution from 10.1 to 12.2 Megapixels. This gives the new model around 20% more pixels in total, but with an actual image size of 4272x2848 pixels versus the 3888x2592 pixels of its predecessor, you’re actually only getting a modest increase of approximately 10% in each axis.
