Not always true. Different cameras have different expressions and different personalities. A camera can get in the way of your vision or it can get a little less in the way of your vision. Experience will make you choose the camera that offers the result as close as possible to your photographic vision or style. You can paint with red paint even tho you prefer blue but no doubt you will be more pleased using blue paint. Personally i feel the Hasselblad offer something unique. Or should say, the specific Carl Zeiss lenses in combination with the format size offers somthing unique.

All those hours spent tweaking the imagery i was now getting straight out of the camera before editing. That doesnt mean the Canon were a superior camera it just ment that it suited my eye better although both cameras were capable of proffesional work.
