Thanks. Just looked at the numbers and the hood mounted on the 24-70 I and it also explains why my perception is different. I also use the hood, but the 24-70II and 24-105 are almost exactly the same max/min lengths with hoods mounted. But go back to the 24-70 I and there is a 1.5" difference at the "min." Looking at the pictures, that is absolutely noticeable.
