If sharpness is your main concern, you'd better get a few prime lenses. They usually over perform any zoom lens.
I agree. The sharpness of primes is really hard to match when it comes to zooms.
Sorry I'm a bit confused... the 24/70... Nikon or Tamron? I'm looking for the sharpest.
Thanks Cheers
Between the Nikon 16-35mm and the Tamron 15-30mm, DXO Mark's tests on the D810 have the Tamron scoring higher for sharpness.

I have the Nikon 18-35mm f/3.5-4.5 G (not the AF-D version which isn't nearly as good), and even mine scored a little higher than the 16-35mm. However, I've seen photos taken with the 16-35mm, and it is no slouch!
I believe the Nikon 16-35mm is weather sealed. Not sure about the Tamron. The Nikon will have a metal mount. Not sure about the Tamron. Those are things you might want to consider. Good luck with whatever you choose.
