Professional DSLRs like the Nikon D4 and the Canon EOS-1D X are hard-as-nails devices which can take a battering and operate in the toughest of conditions. Users with more modest cameras however, have to be a little more considerate about where and when they shoot. In the middle of a torrential downpour for example, not a good idea … normally. The Pentax K-30 is a mid-level DSLR which packs weather-resistance and dustproofing into an entry-level sized camera.
