We've seen plenty of tablets go under the spudger at the iFixit teardown labs, but seldom has a DSLR been gently gutted and photographed for all to see. Today's victim is the $900 Nikon D5100, which just hit stores last week. After popping out the battery (the D5100's only user-serviceable component), the engineers removed the motherboard, 16.2 megapixel CMOS sensor, and everything else they could get their hands on, even going so far as to desolder some wires. The verdict? The camera is very difficult to disassemble -- perhaps because "approximately 4 billion screws hold the device together." Teardowns are arguably more fun than unboxings (trust us, we know), so hit the link below for more camera-in-the-buff shots.
