1. There is no adapter that lets you use a EF-S lens on an EF body without losing many of the advantages of gthe lens.

If the 5D Mark II’s view represented the full frame’s image, then the 7D would capture a much smaller image area. That’s where the 1.6 crop factor comes into play. The crop factor magnifies the lens’ focal length so a 35mm lens on the 7D captures the equivalent area of a 56mm lens on a full-frame sensor (35mm x 1.6 crop = 56mm lens
