I would put in another vote for the 75-150 series E. I got mine from KEH--they tend to note whether the zoom is loose or not. It was a "bargain" grade, cheap and looks and works great.

I find I rarely use it though. I also have the 100mm Ser. E lens and this is my favorite lens in that range. Small, light, great images, fast.

All this is on my FE.
