Thanks Ulrik and Paul.
Typically I mostly add UV filters to my lenses simply for the protection and especially when I am taking coastal or outback pictures - to avoid salt air and dust.
But I don't normally have a filter on wide angle lenses because my experience is that they are more likely to induce flare just as very wide angle lenses are generally more likely to experience flare without filters.
Interestingly, NONE of my Hasselblad 6x6 or XPan (Zeiss or Fujinon) lenses are prone to flare - they resist it very well. Even my CF 50mm FLE has to be very deliberately angled at the sun to produce any flare at all.
BUT, while I find my Leica 135, 90 and 50mm lenses resist flare very well (especially given the relatively small hoods they all have so as to avoid obscuring the view-finder too much), the current Summicron-M 35mm ASPH lens is more prone to flare and must be used with care.
When I first got it I added a B&W UV filter because these Leica-M lenses are so expensive and have small hood protection; my first images had some bad veiling flare. In part this is due to the optical design; but mostly caused by the filter glass and air extend further into the small hood. So I rarely fit the filter any more and now do not see flare in any images.
So, Ulrik I would be interested to experiment with the UV filter, because if it does not add flare in normal use, I am keen to protect this WONDERFUL "like new" Tessar from any mishaps. Are they hard to find? Of course I'll arrange to pay for it and the postage beforehand.
