The Gadget: Canon’s 40D DSLR is their lower end prosumer DSLR, a step above the Rebel series cams. It has, most notably a 10.1 megapixel rating and 3-inch LCD screen, Canon’s latest DIGIC III processor and live view. I used the 30D and more recently the 40D for all Gizmodo’s major liveblogging, so you’ve been seeing what the cam can do for some time now. (Which is also why I choose to shoot the cam sitting atop my messenger bag.)
