NIKKOR 14-24mm f/2.8G ED for D800E

How good is this lens? I have a 28-70mm 2.8 and 70-210mm 2.8 and was looking for a lens below 24mm. Is the 14-24mm a very good lens. Do you think there would be another very good quality non zoom that might be a better choice than this? If so, what focal length?

Thanks,

Ken
