I am sure this has been asked, but if you could pick one lens to carry, what would it be ?
Would you go with the 24-70 or the 24-105. The 24-105 is a bit slower but has image stabilization.
Image Stabilization is great if you want to handhold a camera to photograph a still subject with a slow shutter speed. If you need to capture a moving subject (or if you're in a moving ride), you need a faster shutter speed to avoid blur.
That's why I'd rather have f/2.8 or faster. If I'm shooting a subject that isn't moving while using a slow shutter speed, I'll use my tripod.
I see your point. But I think a lot of it depends on the situation. If you have a family along and want to keep tripod use at a minimum, the IS can be a great benefit. I bring my tripod for fireworks, but the family fusses if I drag it along and take too much time to set up a lot of shots. If I can shoot on the go with IS, it might not be as good as a tripod shot, but it's better than no shot.
I was just going over my shots from last year's Christmas parade. In 2010 I shot with my 17-55 2.8 with IS. This year I shot with my 50-150 2.8 withOUT IS. I ended up with a little shakeon more shots, and I am coming to the conclusion it was the lack of IS.

LOL!! I am so glad I chose a system with in-body stabilization!! With all there is to think about when using a DSLR, that is one issue that never enters my mind. My pea brain couldn't handle any more required information. OVERLOAD, OVERLOAD!![]()
