A couple of days ago I ordered a new / unboxed DA L 18-50 - the non-HD version, as supplied with (and separated from) the K-S2 and other kits. Years ago, I owned the best version of the DA18-55 WR but sold it, and ever since I wished I didn't, as there have been numerous occasions where I'd have liked a wide-to-short-tele WR zoom. So, when the 18-50 popped up at a very attractive price from my favourite supplier, I bought one. Sadly, I've had to send it straight back, due to de-centering that made the right side of shots noticeably softer than the left at the wide end. I'm not sure if it was an optical issue, or the result of the slightly wobbly, dual-cam, extending-barrel design. Either way, within half an hour of testing, I confirmed my initial suspicions and packed the lens up for return. Oh well... can't win 'em all
