As an old PENTAXER I had made false economy already the most diverse foreign lenses and was mostly disappointed. Even from the haptics her is every PENTAX lens and this particularly highly recommended. The shots with my K-5 are elevated in terms of sharpness and color fastness doubt. A comparison with the highly acclaimed and because of at Pentax superfluous because already built into the cameras and therefore not necessary for each objective "loose Electronics", much too expensive Canikon & Co lenses, this holds any creep. Also priced the DA is 55- 300 attractive. Therefore, 5 stars!
