Query: do not touch this camera

I bought this camera for a holiday in the Caribbean. After using it for 20 minutes in shallow water, it failed. I returned it to Pentax who (eventually) claimed the warranty was void because it had sand on the battery cover which has compromised the waterproofing. This is nonsense. How it could have worked under water with sand on the battery cover was beyond the Pentax technicians ability to explain. Also, the possibility that any sand on the battery cover had lodged there after the camera failed was also too much for the Pentax customer service (an oxymoron if ever there was one) to explain.So, lousy camera and even worse customer service.
