              K-7 what a nice camera but terrible sensor. D90 murders it that is why the K-7 has lost this one

              You might also consider that Pentax is widely renowned for it's quality of glass.

              okay, thanks for clarifying! I was just afraid that the fact that nikon is more well-known had affected the decision, but now i see differently. I just bought a d90 30 minutes ago, it's arriving in 3 weeks, and i'm very excited-- the nikon-ys among my friends and family finally convinced me.

              Hi Rebec, the D90 and K-7 are very closely matched, we should probably call it a draw!

              Snapsort is calling the D90 a winner because it scores slightly better on the flash rating and on the low light capability rating.

              I don't think you can go wrong with either. You might consider though that the Nikon D90 likely has more lenses, flashes and other accessories available to it than the Pentax, since Nikon and 3rd parties produce a wider variety of lenses etc for the Nikon lens mount.

              I am wondering why the d90 wins between the two, since the k-7 seems to have many advantages, with the only disadvantage being a slight difference in low-light capability. Please explain your reasoning, snapsort officials?
