To show that one unit is or is not more powerfull than the other, images that show that both have enough power to handle a given situation say nothing at all. You are comparing the wrong things. It's true, though, that for the extra weight and bulk, a CT 60 only provides one stop more than the smaller CT 45. Comparisons with small on-camera units usually are biased by zoom-settings. You can put a lens in front of a CT 60 too, and it then will have more reach than most small units at their extremest zoom setting.
