You are right there Mike, I experienced ghost images, like watermarks in one set of images, eventually I nailed it to the UV filter which I had been advised to use in front of the lens. I had five 52mm UV filters at that time, frame the 'best' coated Nikon and Hoya to no-name cheapies. I replicated the conditions and tested them all, in fact some of the cheapies did a better job than the 'best' but they all degraded the image significantly. With the exception of my Nikkor 80-200 f/2.8 which I am unable to remove the filter for fear of damaging the lens, I got rid of all my UV filters at that point. I have suffered very occasional marking on the front element as a consequence but I have yet to see any degradation of an image as a consequence of the slight marks. Unfortunately I seem to have deleted that set of images from about 2010, probably during one of my culls! One 'accessory' which I do recommend is to use the lens hood, that can increase the contrast in an image, especially when using wide lenses.
