Originally posted by normhead The only way I can see this kind of complaint having a chance would be demonstrating that the damage was caused by a manufacturing defect.
And this is exactly the point many people miss: a warranty isn't an "all risk" protection. It only covers manufacturing defects, unless specified otherwise in the warranty description. And not only for Pentax, or cameras, but for all goods in general...
And even if there was a defect with a seal, the warranty would only be limited to the replacement of the defective seal, and will not the other damages resulting from the defect. Again, it's basically the same thing as with any other goods...
I believe that some photographer's associations membership includes specific insurance covering gear, at least for things like theft. Or you can also look for gear insurance (like insuremyequipment.com). But even then, you will still have a deductible to pay... For example, insuremyequipment.com cover water damage but you will have to pay a 500$US deductible, in addition to the minimum 455$US annual fee... Looking at this, for me, the 542$CAN (about 400$US) Sun is asking you to get your 645Z back in shape looks very reasonable...
That said, I totally understand that it s*&% when someone buy a high end weather sealed camera only to find out that warranty coverage is quite limited if there's a problem with the weather sealing. But we have to know that warranty coverage isn't the same as an all risk insurance, and that WR only means that the gear has a better probability of sustaining bad weather condition than a non WR one. This doesn't mean it's 100% failproof...
