I'm travelling to the USA next month. I just bought a K-5. I already have the DA 12-24 lens which is great for landscapes or unique shots. I'd now like to replace my rubbish Sigma 18-50mm lens that I got with my K100D. I expect it will be on the camera most of the time while I am travelling. I don't expect I'll need a bigger zoom than that.
Any suggestions about the best quality I can get, preferably for under US$400 (as far under as possible as it is going to bite into my travelling money
)
Thanks
