I'm one of the ones you see with the red stripe around the front of the lenses (Canon "L" glass). When I bought my first "L", a 70-200 f/4, I decided if it wasn't dramatically better than my Canon 55-200 that I would send it back and be happy with the inexpensive lens.
It was better, *much* better, too much better!
But 5x better? Hmm...
It's easy to get spoiled by the premium lenses, they are sharp wide open, corner to corner, especially so on 1.6 crop cameras. Canon and Nikon have at least three tiers of kenses; the $100 kit ones; the $300 mid-range; and the $900 premium (these figures are *very*
approximate). There is certainly diminishing returns as the price goes up, and some of the mid-range lenses are as good as the 1.6 sensor can use. But there's no mistaking the feel of the premium lens, they seem to be made out of a billet.
Btw, if you don't use some sort of camera support you may not be getting much advantage from the good lenses.
I don't use "auto", but now if I see someone looking at my lens I'm going to pop up the flash at night, just to mess with them!
The best combo I ever saw at WDW? A Canon 1D with a f/1.8 50 mm! C'mon cheapskate, spring for the f/1.4!
