Originally posted by BigMackCam Taken at face value, I'd agree. The problem is, there are so many variables with weather resistance. The K-5 sensor spot and AF issues weren't influenced by user practices, weather conditions or any other factors - they either existed or they didn't. With weather resistance, each circumstance is unique. Still, given Ricoh's claims, you'd expect half-an-hour's use in light rain to be OK - assuming all other best practices were followed...
The K5 problems were, however, caused by poor design (buttons falling off), poor manufacturing (sensor spots), and poor quality control (AF errors in anything other than broad daylight on some cameras due to cumulative results from out of spec components))
We now have 2 complaints on one web forum that may be caused by poor design (seals not up to the task due to a design flaw, poor manufacturing (seals or seats not manufactured correctly), or poor quality control (seals on some (or all) cameras not installed correctly).
Giving both posters the benefit of the doubt that their use descriptions are accurate, neither camera should have failed, even though the OP has indicated his camera's problem wasn't exactly weather related.
Two complaints of the same kind on one web forum for a recently released low volume specialty product doesn't look good.
