It's a very good 28-70 lens. So good that I almost never use my Zeiss 35 f2 which is a great lens, and so good at 50 that I don't usually bother to put one of my better 50s on.
It just sucks at 24. 70mm is good, not great. It's also too short. Hoping that Nikon comes out with a 24-120 f4 with great IQ and a fixed short.
