The Canon 1Dx is the latest professional flagship DSLR from the company, aiming to replace both the 1Ds Mark III and the 1D Mark IV professional cameras. With both of those models being discontinued once the 1Dx hits shelves, that means that it will have to be a camera that can satisfy not only the sports, action and celebrity photographers with blazing speed, but can offer images of a high enough quality for fashion, studio, and landscape photographers whose work frequently ends up in print. With 12fps full resolution RAW shooting, a new 18-megapixel full-frame CMOS sensor, and a new sensor design that allows for faster image readout with less noise, Canon may have accomplished their goal. This goes without even mentioning the new compression and sensor design that should eliminate moire and artifacting when shooting HD video. All in all, the Canon 1Dx has lofty goals, and is set to ship out at the end of March of next year. Read on to see our first impressions in using Canon's impressive headlining DSLR.
