the hasselblad, or leica, or any camera you care to define as "the best" is **** all use when it's sitting at home, and you missed the shot of your daughter's first fish, or that car that flew over the crowd missing everyone, or that incredible sunset/rainbow/building/moment.
in that MOMENT, to MAKE great picture, the BEST camera is whatever you had with you. a box brownie will do - some amazing photographs have been made on something as rudimentary as a box brownie. Whatever you had that allowed you to capture the best photo you could, with the tools available, IN THAT MOMENT. The camera that allowed you to avoid that "oh man, I wish I had a camera with me. except I don't, because my best camera is so good I can't be arsed lugging it with me - would have been cool if I'd had it" statmement.
If you find that argument patronising, just keep on reading the lens sharpness tests. Mean time, I'll stick to making the best image I can when I see one, with whatever tool I have available.
(sorry, the last statement may have been patronising. the rest of the argument is certainly not intended to be). "It's all about the photographer, not about the kit".
