I totally agree. Generally speaking, I find that photographs made with these Tessars are as sharp as promised by the famous name they bear. Same thing happens, however, with the less sought-after Novar Anastigmat models, which thus are a cheap and smart choice. Both lenses are usually affected by a general flare to which today photographers are totally unaccustomed. Not a "natural flou" effect, but a general glow which surronds wide areas of highlights and reduces midtones' contrast accordingly. You can either consider it a defect, or better a valuable feature that will add a "vintage" touch to your images.
I have been informed that this kind of uncoated lens still produces outstanding results. Perhaps you could add your opinions.
