I bought it new from B&H in Nov 2012, and took very good care of it. Never dropped or took out in bad weathers. Glass is very clear with no scratches/dents/fungus/etc. The lens is one of Pentax's best zoom lenses and is great for shooting portraits and small stage performances. Early versions had SDM motor issues but my copy was in a later batch and I had no issue at all. Focusing is always smooth and quiet. I still like it a lot, but use it rarely because of its weight. I've switched to Sony mirrorless.
