I want. I know you are right, we want FF. And all of us want FF. But truly, it's not a matter of want that we are discussing. We could ALL use an FF if we could. But if I could only afford and have one camera, would it be an FF at this point of time? Probably not. There will be pple who will, without a doubt, choose an FF as the only camera.
But you know many many pple who have a decent compact camera even while owning an SLR isn't it? Because there are just places and ocassions where an SLR is inappropriate.
The guy who only has an FF as their primary camera is usually using it in situations where he has an assistant to carry things around for him, or in a studio, or in a controlled environment.
I'd pass my compact camera to the waiter in the restaurant so that he can shoot a group photo of my ex-classmates during a gathering. I'd ask my wife to take a picture of my kid and me with my compact. I'd go hiking with my compact so that I dun have to weight another 4.5 kgs more. I'd bring my compact on purchasing trips so I dun have to lug things around on 8 hour trips. When I go to trade shows, I'd bring just my compact to take product shots.
But, do I still want an FF? Yes, I do. Till death do us part.
