Yes here is the deal with your 3ccd you probably have about 650 lines of resolution. 5D has 1080 lines of res. now that already is alot. so when you add shallow depth of field with the lenses you have a nice picture. 2k image is 2048×1280; HD is 1920×1080; 1k is 1124×964 so in some film shoots they use 2k and blow it up to cinematic resolution. so HD is closer to 2k, but here is a dilemma with the 5D it is compress coming out of the camera to 20mbs with a 8bit data rate which is horrible compression but can;t tell with the high res image. also the HVX can use a BNC HD out to get 4.2.2 and that is better than 4.1.1 5D colors i could explain more but it comes down to a physical comparison.
