Nikon 70-200 f2.8 FL problem

An issue has developed with my lens. A halo appears on the right side of the image. It appears whether or not I use my lens hood, and at various zoom lengths. Any guesses what the problem might be? It does not appear when using any other lens.

Attached images were taken facing AWAY from the sun.

If it doesn't happen with any other lenses, then you can rule out a problem with the camera. Did you ever drop the lens? Maybe an element came loose and is off center, dropped or not. That's what it looks like to me, but I don't have it in front of me. You may have to send it to Nikon to have them look at it. Try looking through it and see if anything looks abnormal.

Do you have a lens filter on?

Lens has not been dropped. I’ll have to check which type of filter is on when I get home. I believe it is UV.

Take filter off and take a few test shots.

You may be onto something. I removed the (clear) filter and took a couple of shots, and could not see the halo. However, it was just before sundown and had gotten pretty dim.

I'll try again in the morning. Maybe experiment with attaching the filter at various degrees of tightness and see if the halo moves accordingly.

Thanks.

P.S. Filter is B+W XS Pro Digital007 clear MRC Nano 77mm.

The camera probably will still take a picture inside a building or house also.

Understood, but I wanted to use a sky background. Unfortunately, the halo is still there without the filter. That would have been great if it was as simple as that.

Looks like a trip to Nikon is in its near future.

Steve did you have the lens hood on or off when you tried without filter?

The lens hood was off.

So, when you put the hood back into its proper usage location, aka 'on', what are the results? I'd certainly make that verification before engaging in any $$$ related actions.

Looks like I was mistaken after all.

Thanks to your inquiries, I decided to test the lens on another camera, and saw no halo.

In spite of not having noticed the anomaly using other lenses previously, I took some shots with my 50/1.4 and sure enough it is there, so apperantly it's an issue with the D750. Hoping my local repair shop can figure it out.

Hopefully a sensor cleaning will cure it.
