Canon EOS 400D


Nowadays 10-megapixel cameras are widely available and also in our reach. And not only in professional use but also for personal use 10-megapixel camera becomes very handy. Today I am going to talk a little about Canon EOS 400D also known as digital Rebel XTi.

In my previous article I wrote about how I choose my 1st pro camera. Well it was not all wild guess but the spec of the camera also has a great influence in my decision.

The journey of Canon EOS 400D started on August 2006. Till then it becomes one of the most trustable partner of a photographer. It is the successor of the popular EOS 350D, with an upgrading 10.1-megapixel CMOS censor, a larger continuous shooting buffer, an integrated image sensor vibrating cleaning system (first use in a Canon EOS DSLR), a more precise 9-point auto focus system from the EOS 30D, improved grip, and a bigger 2.5-inch (64 mm) LCD with 230,000 pixels and a larger viewing angle which replaces the top status screen.

The only similarity of 400D with D80 and Alpha A100 is the pixel count and imaging flexibility. Other then that Canon 400D is on the other side of the river with far more advance CMOS image sensor as opposed to the CCD variants installed in the D80 and Alpha A100. And so, it is completely a different level of imaging performance and value comparison altogether.
