I have failed more than once to keep my camera gear dry. First place to fail is usually the lens mount and with no sealing there (non WR/AW lens) damage will happen sooner or later with any brand. Then there are camera ports which are tricky to seal correctly - it is very easy to misplace the port covers even slightly and there you go - farewell to sealing.
I used my first K-1 in very bad conditions (hard rain and heavy wet snow) on purpose but that did not kill it. A slip on icy rocks and dive into ice cold Baltic Sea was too much though.
I have been using K5 6years with over 100K - snowing, moderate raining and up to -35°
C with smc 18-55 (later I bought DA*16-50) with DFA 100mm WR and sigma 70-200/2.8 APO, all lenses are still ok with no problem, as K5.
K1 - heavy snowing, light rain, I guess not less than -10°
C with DFA 24-70, DFA 100mm WR when was raining or snowing... sigma 70-200APO couple times when was light snowing. mostly I used DFA24-70. sometiems when was really heawy snowing and I had camera on tripod I coverd it with a plastic bag cover and after shoting when camera was dry and clean and temperature balanced I put the body for overnight or longer into a closed box with Pelican Reusable Silica Gel Hydrosorbent Unit - 40g - 1500Dand couple more smaller bags with silica. K1 is dead after a year and half of using. yes with 112K but K1 is rated for 300K.
I didn't even use always WR lens with my K5 and didn't use silica after shoting at all. camera still working normal as all lenses. I guess I was just unlucky.
