Pentax k10d water resistant and SR test

On behalf my friend, he just bought a pentax k10d and did some test last week.

His original post is ihere in Chinese: http://mitbbs.com/article_t/PhotoGear/20190825.html
I translated it and post it here by his request.

Since there is no weather resistant lens so far for k10d, he wrapped the camera mount tightly with some plastic wrap.

water flush for about 1 minute.

Actually, the body material is very good for water resistant. So the water run off very quickly.

Check the body after flush. Some local places have traces of water, but can be wipped out easily. No water inside the SD card compartment.

Take a picture with K10d now, everything is ok after this water flushing test.

He also did a SR test, you can tell the SR effectiveness easily.

Sorry to say this about your friend, but this is plain stupid. He has no idea what "water resistance" or weather sealing means. The tap water is high pressured, even my diver's watch rated for 150m had warnings against putting under running tap water.

Hey, but if he has $1000 to burn, what do I have to say?

I could never do that to my k10d.

Re: Pentax k10d water resistant and SR test

Yes, he knew the difference of water resistant and weather resistant.
He bought it with only 500 dollars and don't care money like us.

So he tested it for us. It is fun and informative to look this test without your risk.
I did not ask you guys to mimic his test, just let you know what k10d can do.

I believe NedB had some comments when someone tried that with a Samsung DSLR.

Ned, are you out there?

Re: Pentax k10d water resistant and SR test

Sorry to say this about your friend, but this is plain stupid. He
has no idea what "water resistance" or weather sealing means. The
tap water is high pressured,

Liquid in a stream that is surrounded by ambient pressure has that ambient pressure. The "danger" is the velocity of the liquid which on impact becomes a pressure again (dynamic pressure/impact pressure). However, until they hit something, the drops are slowed down by air resistance and accelerated by the gravity field, so will reach a terminal velocity, just like rain drops

I'm not saying that this experiment was safe or sane, but tap water isn't pure evil The impact in this experiment might not have been that unrealistic for a tropical rain, but the amount of water seems a bit excessive.

Cheers
Jens

You never know if it's well sealed unless

the body was fully disassembled right after the water test for close inspection.

Perfect quote! If that guy doesn't care about money, have him send some of it my way.

Well at least he had the sense to use filtered water

THANK YOU very much for posting this. Please extend to your friend the thanks of this forum's members for undertaking such a test and posting the results.

I don't understand why some folks are upset by this useful test but it's likely that a majority of readers here will find the information reassuring.

Thanks again.

Re: Thank you very much for posting this

Yes, thanks for posting the test. Makes me feel better about using my K10D on the beach, in the Mexican jungles, etc.

It sounds like there are some users here who have propably never taken their cameras outside. Now THAT, is stupid!

People here are not upset, it is more of a "DON'T TRY THIS YOURSELF" type of warning. This is NOT what the camera was designed to do, and it is NOT a useful test. I mean what did he show? That the SD compartment was dry and the camera operates after being flushed by tap water? You have no idea how much water is in the chassis.

but it's likely that a majority of readers here will find the
information reassuring.

I can't see how you can deduce that from a test under a condition which the camera was not designed for and with a result unverified and unclear.

Can you give me an exact quote where you get that impression?

Or would you subject YOUR K10D under this "test"? If not, are you one of those "who have probably never taken their camera outside"?

Re: Thank you very much for posting this

I don't think this tapped water is as strong as storm in some place. You need to know how well this weather resistant work in light rain, heavy rain or even storm. From this point, how can you say this test is not useful at all or even "stupid"?

As long as the camera works normally, who cares to check if any traces of water may exist in body? The camera works pretty well so far after testing.

At least, you can know that K10d still works well after this extent of rain situation. Maybe it is not useful for you, but useful for me or some other guys.

Where is the lens?

I would hope that he repeat the test with a lens.

I am going to go out on a limb and guess that there was not too much water in the chasis if it was still taking pictures.

I can't see how you can deduce that from a test under a condition
which the camera was not designed for and with a result unverified
and unclear.

Well, what I deduced was that the splash resistance is more then just marketing hipe, and that it is probably ok to go out in a light rain with my k10d. I am happy to get that reassurance.

While I would not put my camera under running water, I am glad someone else did. Sorry if that makes you angry.

Re: Thank you very much for posting this

Do you really know exactly what conditions the weather sealing was designed for? This 'test' is a very reassuring success where Pentax marketing claim has been taken to the limit.
Dont let those tears anywhere near you K10 though! :).

Re: Thank you very much for posting this

I would also like to thank the brave soul who sacrificed his camera for the sake of this test. I always wondered how well the K10D was sealed. Although you wouldn't likely find yourself in this situation with day to day shooting, it seems like the camera can withstand a good amount of water.

That's the reason there's no lens on!
