Very nice lens, I had one but I sold it. They sometimes show a blue spot in the middle of the frame in some high contrat situation, no a lens defect, is caused because of the flat rear element. Try taking a picture of something black with a white background at f22 or f32 and you will see it. It is a very nice lens though. You should use a lens hood, is prone to flare

In my knowledge the infamous "blue spot" is a problem that raises only with digital sensors, shooting film I should be immune  . I've taken note about flare tendency, though I've noticed nothing so far. I've a roll in camera with most shots taken outdoors, we'll see what comes out.

Taken note. I've several ideas floating around, but time is a tyrant .

Yes, you are right. Only happens with digital cameras, it is said that some brands are more prone to it than others. The flare(I should say lost of contrast) is also caused by this reflections at wider settings
If use it with film you will have no problem, some digital users have never noticed it either
