Don't waste your money on the C905, the camera is rubbish just because it's 8mp doesn't make it any good, the pics are far too heavily post-processed to be any good, at the least the k850 & c902 can make nice daylight photos the c905 can't even do that.
To show the 8mp resolution doesn't make the quality any better than a phone with a 1.23mp resolution i made a couple of 100% crops it's not a direct comparasion the photos are roughly the same object in the same conditions.
