The K30 with the WR 18-135 lens is an ideal travel trailer. The lens works quickly and quietly, much better than the other kit lenses and even faster than the lenses with SDM control. Have tried everything and am happiest with this combination. Also in weight, it is still unproblematic. The image quality is at the correct setting perfectly fine. Even indoors succeed in ISO 3200 is still very good and without noise. In order for the faintness of the lens is well balanced. The outdoor area in bad weather you are with this camera / lens equipment on the safe side. The seals are effective and allow a careless handling in snow and rain or a white water rafting trip. If even a K30 casing, then a WR lens to, otherwise it makes no sense. Then reaches a K 500 for good weather. Overall, a perfect combination for an excellent price-performance ratio. Unrivaled in this compilation. Class Pentax / Ricoh!
