Veiling flare (the haze from sun reflections) is mostly an internal blackening problem I suspect, as everything Nikon makes is at least multicoated. I remember noticing that Nikon Monarchs with full multicoat had a bad problem with veiling flare over about 12x, while their Buckmaster multicoat only lower line did not, even at 18x. Of course the Buckmasters have other problems. They appear to field stop them down considerably, giving great depth of field, but a terrible apparent field of view, resembling looking down a cardboard tube. The newer Prostaffs even seem to take care of this blackening issue, so it may be a problem they've beaten. My dad's rimfire target EFR controls flare very well.
