As far as I can make out, no. It's the nature of the beast. The only thing that seems to make a difference is the amount the rear element is recessed - a deeply recessed rear element will be less prone to reflections than one that's flush with the lens mount.
If you have a choice of suitable lenses, use the one most deeply recessed. If you have a convertor with a recessed rear element, you could try that. I suppose an extension tube could help, but not very practical in most situations!
A more realistic approach is to develop your PhotoShop technique so you can remove the problem. If a flaw is visible in PS
, there is always a way to isolate it and either remove or disguise it - the trick is finding the right tools. Some tricks I've found quite useful have come from the world of fashion/glamour photography - there's loads of books on the subject.
