Help Needed: Is my fuji 23mm a bad copy?
#11
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.

This has nothing to do with the coating - a weak coating would show up at all edges not just the lower left ones.
 

Hi Klaus, thanks, this attachment is from image center...

 

I'll contact Fuji and see what they say...

It's not extreme but it will have an impact.

I had the opportunity to test another 23mm/1.4 lens, that lens behaves more or less the same as my copy. 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.

What is your opinion?

That's quite good for f/1.4
