I just got this lens on a cheap deal, but after playing around with the lens a bit I notice some very serious flare issue. Take a look at the pics below See the moon like spot in the sky, is the flare from the street light This shot taking at f16 These shots taking at f1.7, looks like it all circulate the center of the frame on the opposite side of the light source. I used my 25mm f1.4 which also has the same nano surface coating and wasn't able to produce the flare. I know that wide angle is more prone to flare, but this looks like something very unnatural and is out of control for a lens that Leica would certified. Anyone with the lens experiencing the same issue or I simply just got a bad copy ? Thank you for the input in advance. P.S the original owner was nice enough to give me the original recipe, is warranty from panasonic transferable or I can fake as the original owner with the original recipe.
