I have to jump in here and offer nothing useful.......
I\'m an engineer too, like many of you seem to be in this thread... -- I, however, instead of trying to work my passion as if it were my profession, rather like to take refuge in protography from the daily drudge of calculus, ballistic coefficients, kinetic potentials, and other things that make one\'s brain hurt.
Geez people... photography is art and as such it is very subjective.... So think of the comparison this way -- Look, Ma -- no math!
I have an assignment to shoot...let\'s see... some Rolex watches for a Jewelry story catalog.. I will shoot this assignment with either a 7d or a 5d.....
I choose my trusty 24-105L for this.... its awesome sharpness, ability to focus to 1.5ft, and its zoom range appeal to me. Of course, IS helps too!
I set up my lighting and \"scene\" or layout of products WITHOUT regard for any camera -- just like I would do it if I had already chosen the camera. I don\'t care at this point.
I compose the scenes in the viewfinder the same way with each camera and shoot a series of test shots..... meaning, I take the same shots with each camera -- I don\'t care about sensor size or pixel density. If I move up or back, its not to compensate for larger VS smaller pixels at their relative densities within their respective sensors --- I only move to make the same composition in the viewfinder. I\'m just as likely to change focal length to achieve the same thing. Since this is a test, I would take test comparable shots by both moving and changing focal length with each camera. I only care about the finished product.
I either print or view the results on screen along with some assitants and maybe the client and choose the best. Done.
If I had a 5d2, I would do this tonight and post it tomorrow for you all to choose....Unfortunately, I only shoot crop bodies......
