    I've driven past this scene every morning for the past few weeks and this morning, I finally had a camera with me:

    AF-S Nikkor 24-70mm f/2.8E ED VR works great across the whole range of mm's, but starts to get a hot-spot at about f8.
    AF-S Nikkor 70-200mm f/4G ED VR - not tested yet.
    AF-S Nikkor 200-500mm f/5.6E ED VR - not test yet.

    I have a few older Sigma lenses I have not tested either.
    I removed the UV filter from my Sigma 24-70mm f2.8 IF EX DG, and the slight problem with hot-spots I was having disappeared. I'll have to try that with my Nikkor 24-70 as well.

    You are correct! I've had it for over 20 years. It has seen a lot of use.
