I do have an AF body, F100, which to me is one of the biggest bangs for the buck out there. But I also would like to use it on my FM and soon to have an FE or FM3a. I know that complicates but I'm also looking at this one which gets good reviews, nikon 28-105 3.5-4.5 IF.
My only problem with the 28-105 was the 62mm filter size--the 28-70 is 52mm. The 24-120 takes a whopping 72mm.
