How do you use your 24-70 (vacation, etc)? I know you have a few lenses to choose from in your kit.
For almost everything... It's the lens I leave on when the camera is in the closet, my usual walkaround lens, portraits, travel and landscapes, etc. Basically, if I'm not shooting something where I know I'll need another lens, the 24-70 II is on the camera, and if not it's usually in the bag.
