I'm wondering whether it will still be WR with the pop-up flash activated..
On Sunday we got caught in a downpour and ended up well and truly drenched, about 20 minutes of driving rain. Fortunately I had a plastic bag big enough to put my big Sigma zoom, my mobile phone and the camera's spare battery in it. The K-30 was afforded no such luxury. Luckily it had the 18-135 WR lens on it.
I took some photos but found out that there are some issues with shooting in the rain besides the survival of the camera. The biggest problem was that I couldn't see a damn thing through the viewfinder (because it and also my glasses were soaked) so I just shot blindly and got lucky on a few shots. I set focus to 11 point auto (which I had never used before) and let the camera guess - it seems to have done a reasonably good job of it.
One would probably need a large eyecup to shield the viewfinder from the rain as the moment it gets wet everything becomes a blur. Live view was perhaps a bit better - but with the heavy rain impacting on it I couldn't really figure out what I was seeing. If I had my left hand free I could have probably shielded the LCD and been able to see it better. It was however not that difficult to read and adjust settings such as aperture and shutter speed (but the smaller text of the menus was impossible to read)
The flash is also a bit of a problem, as you can see from the last photo whic is shot with the pop-up flash. Nothing wrong with the flash itself but the rain droplets sort of ruin the photo. They are not on the lens but in front of the camera. I somehow managed to keep the lens reasonably dry for the first few minutes by keeping it pointed down or away from the wind direction as much as possible but the droplets falling just in front of the camera are impossible to avoid. Note that whether the flash is open or closed makes no difference to the weather sealing. The flash door has no seals - the seals are further in at the hinge. The flash was actually swimming in water when closed, but the water doesn't get beyond the compartment. If it did I think it would have immediately appeared in the viewfinder, which is just below it.
As son as I got home and got myself dry I set to work to give the camera some TLC and also to find out how well the seals held up. I did find some issues but probably I have subjected to worse than it was designed for. I found some ingress of water, on the level of a few droplets, in all the doors. The SD card slot was the worst with the edge of the card being wet. There wasn't enough water to seep into the slot and the rest of the card was dry.
There were also signs of water, albeit minimal, around the edge of the battery compartment (further in from the seal) and even a few traces on the bottom of the battery.
There was on the other hand no water seepage at all into any other parts of the camera that are visible or accessible, such as inside the viewfinder, in the mirror box or the inner parts of the battery compartment. The lens flange seal also appears to have worked perfectly as did the seals on the lens itself as there was no trace of water or even condensation visible.
My guess is that if I had spent much longer in those conditions it could have resulted in damage, the weakest point appearing to be the SD card door. However if I had spent any longer I would for sure have removed the battery. Even if in the process I got some water in, without the battery the water would be unlikely to cause any damage.
One thing I tried to keep in mind (but failed to on several occasions) is to avoid zooming in such conditions. No matter how well the camera is sealed when one zooms to longer focal length physics dictates that the lens will have to suck in air from somewhere to fill up the increased volume. So that air is going to come in from somewhere and if that somewhere happens to be wet then the air will carry that water in with it and I suspect that it is why I got that water inside. The only way around this problem is to use a semi permeable fabric (such as goretex) to allow air in but not water but it seems that Pentax did not do that, possibly because it would add too much bulk to the camera (it has to be quite large to allow air to move quickly enough for an extending zoom lens).
The other thing which many people tend to forget (or to not even know) is that even the best waterproof equipment should be taken care of and properly dried out after being subjected to wet conditions.
What Pentax seems to forget is giving us some guidelines on how to care for the camera in wet conditions. In the manual there seems to be no mention at all of the weather sealing. No mention of precautions (except telling you to not allow the camera to get in contact with water, and to wipe off droplets from it if it does!). There is no mention of how often the seals should be replaced, or whether they need any regular maintenace (such as applying silicone grease or something).
