Personally, I only photograph for the web nowadays, so I hardly ever need the resolution. It doesn't quite change the fact that "if the picture ain't good enough, you ain't close enough" :) Evin: Very good point.

It doesn’t quite change the fact that “if the picture ain’t good enough, you ain’t close enough” :)

When zoomed out all the way, you get 3 times as much light, but you're only interested in the middle of the picture (1/9th of the frame), so you end up with about a third as much light being used. Do an experiment: take the picture zoomed out all the way, at ISO 100. Take the same picture zoomed in all the way, at ISO 400 (to more than compensate for the light loss). Crop and enlarge the ISO 100 picture to the size of the ISO 400 picture. Optionally perform some noise reduction on the ISO 400 picture. Which looks better?

You are quite right about the light loss, and it generally meant that I had to take portaits in the sun, or at least on a bright day. Hey, thanks for the reference.
