it makes sense to i guess. why have spend all the $ on the better camera and have mediocre glass. the t2i and even my xsi take spectacular images, so long as spectacular glass like my 17-40 in its sweet spot are attached. all cameras aside, I seriously daydream about having that delicious 70-200 is II. even if its attached to an older body. I just really want full frame for my outdoor and nighttime shoots.
