Ok, let me try and demonstrate my point.... I've copied this across from another discussion board where I've attached a photo I happen to like, a rather enigmatic shot of the father of the bride taking a quiet moment to reflect.
I shot this from a good 50 yds away, hand held, using a Nikon 70 - 200 f2.8 VR II zoom.
At normal viewing size, his trousers look kind of grey; but zoom in to 200% magnification and you can see the detailed pin striping on the trousers, almost picking out the weave!
I mean come on guys, how much resolution do you actually need?
I show this photo to clients on the lap top, then I zoom in to show them what a good pro spec camera is capable of.
Now don't get me wrong, I'm not trying to change your points of view, but you have to also understand why I'm saying this.
(The inset kind of spoils the photo, but never mind!)
