Originally posted by rparmar The improvements from the kit lens to the 17-70 are unlikely to be noticeable, unless you are trying to address a key limitation you currently have. Whereas getting something totally new like an UWA, macro or FA Limited would change your options.
I had a Sigma 10-20 and a Tamron 90mm Macro. I never got along with the ultrawide mentally, and the tamron was good, but the only macro I do is floral, so the DA 35 is plenty good for that.
I spent an hour reading reviews tonight and was fairly disappointed that the 17-70 has as pronounced, if not more, distortion at the wide end.
I have this silly overlap of 18-55, 35 Ltd, 50 1.4, and I'd like to simplify some of that.
Really, the best solution is probably the DA 15. I could do DA 15 / DA 35 / DA 55-300 as my only lenses without much difficulty. I shoot for fun, and when traveling (on a motorcycle, no less) so a compact kit is paramount.
At the end of the day that is a much more likely outcome, and I could sell my M 40, M 100, FA 50, and 18-55 to help fund the DA 15.
I really want a K-5, but I can wait until prices drop considerably.
