Originally posted by Wingincamera I will be ordering either the K-5 II or the K-5 IIs with the kit 18-135 lens and wonder if this lens is not good enough for a camera without a low-pass filter Or should it make any difference at all?
When I bought my K200, it came with a Sigma kit lens, and I was really disappointed by the lack of sharpness. However, when I bought the Pentax DA16-45 f4 lens, suddenly it was a different story! As Adam said, the better the glass you put on your camera, the better the results you will get. The world's best camera with a rubbish lens is not going to show what it's really capable of. Having said that, the Pentax 18-135 is probably a better lens than the Sigma lens I have, and I'm not saying it's rubbish.
If that combination is what you can afford at the moment, go for it and get a better lens later. If you can possibly afford it, I'd suggest buying the camera with a better lens in the first place rather than spending money on a lens which you won't use later. My Sigma lens hasn't seen the light of day since I bought the DA16-45. Check the lens reviews on this site and decide what combination would work best for you. I already have a bunch of lenses, so I'll be buying the K5ii body only.
