VERDICT :
For a little more wider angle, a little more sharpness and better chromatic abbreviation results, i do not think it worth to pay double of 28-70mm. For the same price, you may buy a 28-70mm + 20mm or 24mm f/2.8D and still have 400 bucks in my pocket. If nikon corrects this field curvature problem and add a VR on the lens, then i may highly recommend the 24-70mm. But, my poits go to 28-70mm this time...
Nikkor 24-70mm f/2.8G N ED > 8/10 Recommended
Nikkor 28-70mm f/2.8D IF-ED > 8,5/10 Highly Recommended
For the obsessive–compulsive personality disorder photographers: Ok, do not change the order of 14-24mm , 24-70mm and 70-200mm series. 28-70mm does not fit your range, right.. Nothing to say for you.
