Sorry John. This is what I meant by “utilized”…
The 5D has a full frame sensor but only a portion of it, which is 1920×1080, is being used for the video image. Now my question is, depending on the actual size of each pixel in 5D and 7D, is the 1920×1080 pixels in 5D bigger than the 1920×1080 pixels of the 7D? If this is the case, then the 5D will have shallower depth of field using the same lens.
