I currently have a Nikon N80 with the 28-105 lens, and I decided it was time to upgrade. Quite tired of the noisy lenses I've gotten off Nikon (Also had a 35-70 one a while back) and the horrible AF hunting in low light, I decided to give Canon a try. I purchased a new Elan 7NE with the 24-105 lens.. which failed after 3 uses. I LOVED how quiet it was though, and when the AF worked at all it didn't hunt like the Nikon. I don't know how much my problems with Nikon are the lens the body or just its reputation, but I know I need something more.. It was the Canon's 24-105 F/4, that really drew me to the switch, but now I'm back at ground 0 and I don't know what to try next. Nikon doesn't seem to have a midrange zoom comparable to Canon, and honestly I really don't want to lug around multiple lenses. I did run across the 70-300 F3.5-5.6 VR, and according to reviews has great color and is sharp.. but oh MY is that sloooooooooooooooow 5.6?! So my question is, does that VR really make up for the 5.6? Does it work even when the subject itself is moving (ie concert) and not just camera shake? I got another job next weekend, and I have to move quickly..
