I have a K10d and hope to upgrade soon to the K20d body
my two primary lenses ironically are the 18-55 I version kit lens and a Quantaray 70-300 telephoto Macro from which images produced can be seen here

My question is that many seem to find the photos I've already taken pretty good but do you think that by upgrading to the DA* lenses that much will REALLY change? The weatherproofing on the lenses is a sure attracting factor> especially for my anticipated education abroad in Costa Rica. For now I've gotten more than I could have asked for from these relatively cheap or "lower" quality lenses but is it really worth it?
