I clumsily dropped my 24-70 f2.8 II today. It wasn't a very hard hit. I was kneeling over when it happened, so it wasn't from full waist height, and it was on somewhat soft, sandy ground. Lens still seems to work fine, but can anyone who owns one confirm whether or not it's normal for the extending barrel to have just a little play in it when you wiggle it back and forth? It's pretty minimal, like no more than 1mm of play side to side, if that. I just can't remember if it was like that originally. Thanks.
