Help Needed: Is my fuji 23mm a bad copy? - Guest - 06-18-2014 Quote:Well, if this is the very sharpest setting you can get, then it has a centering problem ( if this crop is from the image center! ). Point is that in the image center everything has to be symmetrical - at least once total focus has been achieved. Hi Klaus, thanks, this attachment is from image center...

I tested another lens (Touit 32/1.8), and the touit lens is perfectly centered. I don't think that all 23mm are decentered. I've just done the test with my sample and it looks pretty decent (quick and dirty test, hand-holding as perpendicular as possible, de-/focused at monitor), 100% center crops are attached.
