>>1251416>I can see why someone would need IS for hand holding 100mm @ 1/30, but for the 24-70 range, it isn't needed unless you have parkinsons or some shit.The mistake you're making is assuming that everyone shoots the same things you do in the same way you do.
Say you're out walking with your girl at night and you want to take a picture of her with some pretty lights behind her. Since it's a romantic evening, you're not lugging your bigass tripod around, but she's just sort of learned to accept that you've always got your camera on you.
The light's around EV3 since you're out on the street. You don't like to go above ISO800 for the noise. You don't like to go below about f/2.8 or so because the shallow DoF will kill the shot. That puts you at 1/8th of a second.
With IS, you can probably handhold that. Without IS, you probably can't.
I'd kill for a 24-70 f/2.8 IS, myself. Shame I'm too much of a poorfag to afford one even if they were to make it.
