Barence writes: Canon claims to have developed a digital camera sensor with a staggering 120-megapixel resolution. The APS-H sensor — which is the same type that is used in Canon's professional EOS-1D cameras — boasts a ridiculous resolution of 13,280 x 9,184 pixels. The CMOS sensor is so densely packed with pixels that it can capture full HD video on just one-sixtieth of the total surface area. However, don't hold your breathe waiting for this baby to arrive in a camera. Canon unveiled a 50-megapixel sensor in 2007, but that's not made it any further than the labs to date.
