 Perhaps stating the obvious but zooms are renowned for more variability. I tried three 17-35 f2.8 (£1500 lenses) before getting one that was the same quality across its range.  And that was only a 2x zoom!   The infamous 18-200mm DX lens suffered at one end or the other. Mine was soft at 200mm ...other people said theirs was soft at 18mm.  What I learnt was ....

1) You have to try the lens you intend to buy to ensure THAT lens is good.
2) Avoid zooms with more than 4/5 x range, the risk of variable quality appears to increase with zoom range

That said, the 28-70 range should be sufficiently far away from wide angle to avoid edge exposure drop off and distortion. And if you intend to use it on a DX camera you will be using the centre of the lens which is invariably the best.


But taking Jonathan's point, trying to get AFS lenses is a better strategy. Changing your camera to a more modern model will make a significant improvement to your photos ....add AFS lenses and the camera will feel more responsive, even though the IQ of AFD lenses may be just as good.
