Right on, again, Gatofeo...I'm always amazed by how many folks back 'way away from their subject before pressing the shutter release. And then they wonder why you can't really see little Johnny's expression when his whole body only occupies 1/10th of the picture. Of course, they probably had little Johnny looking directly into the sun, too, so he doesn't really have any expression other than pain.
Nowadays, of course, if you have enough pixels, you can do amazing things with cropping, but when I was learning the art, the main cropping tool you had was your feet, especially shooting color slides.
I think that putting a zoom into a disposable is beyond the means of our manufacturers; zooms are expensive, and we couldn't afford to buy the cameras, not to throw away, at least.
