If you are shooting with a mix of camera's use the 5D for wide shots-the extra resolution will pull out details in the wide shots. If you cut the 5D and APS-C cameras-7d/6oD/T3-4-5. The difference in sensor size will be obvious on screen. You may have to soften the 5d files in post to have them match. There are many advantages to Magic Lantern-Selecting CBR (constant bit rate) over VBR (variable bit rate). You can increase your data rate by a factor of 1.5 without much problem this helps the H264 files.- less aliasing and moriee. The zebra stripes and false color display for exposure and the focusing peaking-these features give the Canon DSLR cameras features you find on PRO camera's. If you shoot with two camera's you will make your editor a friend for life.

@Oriel - you are 100% correct. That's why outdoor multi-camera shoots are a big headache. In a studio setting, the cameras can be color-corrected (white and black balanced) so that the picture have the same colors, and "shaded" so that the light works best on whatever subject each camera is on.

@Oriel - That's another very valid point.
