    Honestly I've probably done as many comparisons between 1.6X crop and FF as anyone.

    The main difference between FF and 1.6X crop is DOF/subject isolation at the same camera to subject distance.

    Yes, the resolution is a little bettter in the center with FF and the noise is a little better, but its the DOF that you will really notice.

    I can use f/4 zooms on FF and get really nice subject isolation.


    And and at f/2.8 on FF things just get buttery....

    f/2.8 on my "cheap" Sigma 105 macro....




    5D, 85 1.8, f/2........vs..........vs 40D, 50 1.4, f/2....




    5D, 105mm, f/2.8..............vs...........40D, 60mm, f/2.8...




    40D, 100mm, f/4................vs..............5D, 149mm, f/4 (look at the subject isolation in the lower image - it changes the entire look of the photo)



    This was shot at 200mm, f/4 on my 5D. To get this kind of subject isolation on my 40D I would have to use a lens capable of opening up to f/2.5 at the same distance from my subject....
