"Just like the EOS 400D the 450D is primarily made from three materials; a stainless steel chassis, the mirror box which is made of high-strength 'engineering plastic' and the body made of a special lightweight 'engineering plastic' which also provides some electromagnetic shielding. Construction is very good with no creaks or rattles."
