IMHO. The combination of new zooms & new DSLR does give one great flexibilties. I use 17-55 f2.8 with D7000. I NEVER have a moments when I think what if I used primes.
I have been shooting & developing since late 60s, so 50+yrs of Hasselblad, Canon & Nikon. Do check out great zooms before being tied down to only Prime. I know that's not what you asked, since there were no replies, so I thought I'd give my 2c.
