Roger makes a point about coatings, however I've been using some older coated lenses in Turkey and what's noticeable is that I've had no flare with a 1950's CZJ T coated 150mm Tesssar and a late 60's 90mm Angulon, also a 75mm Super Angulon when the multi coated lenses on my Canon EOS have been unusable alongside them. (This is on quite a few ocassions).

Some lenses are better coated than others and coatings evolved, so a late version of the 203mm f7.7 Ektar that Roger refers too is much better coated than the earlier ones (at least with the UK made versions). My coated Tessar is very heavily coated but because of this has a distinct blue tinge, it would need heavy correction for Colour work.
