For sure JM, it was only that the K-x,18-55, 55-300 kit is not available here. I don't think that kit would best suit me. I have found a Melbourne retailer that will do a K-x + sigma 17-70 for $899 or a K-x + Sigma 18-200 for $959.
So far the 17-70 gets the thumbs up, anyone travelled with a sigma 18-200 on a K-x?
