The problem is ... at this price point ... would you really go for the Tamron instead of the Nikkor ?

 

BTW, the centering of the Nikkor isn't so hot.

Looking at the results certainly, the Nikon is looking not so great at the edges @ 24mm, even stopping down it never really catches up with the Tamron and with more CAs.

 It's almost natural to first concentrate on the wide end, the longer end grabbing less of the headlines, but to me the performance at the longer end is more desirable!
