maherkhedder - Ok will have to make a scene

beanzvision - Yep all DOF & highlight clamping makes no difference... Have tried a lot of settings.

Highlight clamping has to help in this case. Please note that it's not "highlight compression" (the one you find in the VFB post tab), but "highlight clamping" in the frame buffer settings of the Render Setup.

Just remember that highlight clamping kills any high dynamic range in your image. So if you are planning to save in more than 8-bits and/or adjust the image in post, it's not a good idea to use it.
In such case you would have to make sure enough samples are devoted to rendering those problematic places, which usually means rendering for a longer time.
