The DA 18-135 / 3.5-5.6 zoom lens is an excellent all-round for all cases. Sealed, solid processed, compact and with very good image quality dimmed already one step in wide angle and at the K-3rd At the long end, the corners at full aperture are slightly out of focus. Only from aperture 11 and the corners are good, but this does not interfere in most cases, as telephoto shots are often composed so that the extreme corners of no importance. Pleasant is also the fast and quiet autofocus motor DC!
I am very pleased with the lens, there for the money for Pentax nothing better.
