I ordered a new Pentax DA 18-135mm, came in just in time to for Friday's trip to the Texas State Fair.
I read all the reviews but, decided in the end, the reason I purchased the K5 was it's weather resistance capability. My current walk around lens the DA17-70 wasn't sealed, and for some reason just is not locking on 100% of the time at the 70mm range just wasn't cutting it ( it's going in for service).
I, grabbed a few shots with K5/ 18-135 seems very nice but it does have some of the discrepancies others have mentioned. The lens is probably going back. Primarily for the poor resolution at 135mm, at the edges it is very very noticeable, I will probably just request another. These re-sized images don't show the anomalies with the lens but trust me they are their. The contrast on this lens is very nice again the re-sized images have muted the contrast ?. Also, it refused to focus multiple times throughout it's range at different focal lengths, I composed the shot, re-zoom pressed shutter button and it would then focus.
I definitely like the K5/18-135 combo great versatility.
