I still don't fully understand some terms for DSLRs. How much of a difference does having several cross-type focus points make? Let's say, 9 vs 1 (comparing t4i to another DSLR). Also, can the human eye detect the screen resolution difference between 1,040k dots vs 920k dots? The website that I got that information from states the 1,040k dot screen resolution makes it easier to tell if an image is really in focus... Is it that big of a difference? Would the one with higher screen resolution win over the other one just for that?
And for the T4i users, is it true that although the T4i offers 12,800 ISO, the highest it can go to produce a good image quality without much noise is 722 ISO, so anything above that would create a lot of noise? (I'm comparing it to a different one that can go to 1,183 ISO and still produce a minimum noise).
Finally... I found these comparisons online between the 60D and the T3I. Are these images accurate for the capability of each camera, or was there some flaw? Because to my eye, in those images the T3i and Nikon D5100 really excel over the 60D, especially the shots of the water. I feel a little disappointed in the color and contrast quality of the 60D from those images...
