switching between lenses doesn't seem to improve things but maybe there is an optical improvement that I have not come across.

You could try using greater magnification to take partial, overlapping images of your target and stitch them together in post-processing, sort of like we commonly do to create a panorama. If part of the cause is because of flare inside the glass, this should reduce the flare-to-image ratio (I'm not an expert so I just made that term up) so that at equivalent magnifications the flare should be less noticeable.

What is your output target? Print? Web? For a "reality check" make sure you're not zooming in more than what your viewer/customer will use. Printing an 8x10 may help you determine whether this problem is serious or not.

Best wishes,
Sterling
