Really weird, and totally off topic, but I think I used to work with this guy at a cell phone company. I never knew he was into cameras.

well I don't hace a picture of my dirty camera but just imagine how the camera was after this picture.
Taken with the DA* 16-50mm ad K20.



At the end of the day I showered the camera and lens. Perfect combination and the sealing works great.

Pentax should really focus on selling its cameras to the porn industry, been WR I'm sure that could be very handy....

Hell it helped win the format war for VHS

All Pentax sealed bodies are equal in rain.

Try it out. And post pictures.

Actually the sealing of the K200D should be almost as good as the K20D's and K-7's. As long as you couple the body with a weather sealed lens of course.

From various Pentax brochures, you can see that the number of seals, and the level of claimed weather-proofing, steadily improves as you go from K200D > K20D > K-7:

K200D
HERMETICALLY SEALED: DUST AND SPLASH-PROOF BODY.
With the PENTAX K200D all weather is photography weather. 60 seals on the body and 14 on the battery grip ensure that moisture, dust and sand cannot wear at the camera. Additionally, the fbreglass reinforced polycarbonate housing with high-grade steel chassis offers the necessary robustness to stand up to the rigorous demands of daily use.

K20D
WATER OFF A DUCK’S BACK: A COMPLETELY SEALED BODY.
The K20D makes light work of heavy weather. 72 seals on the camera body and 38 seals on the battery grip combine to ensure that humidity, dust and sand cannot adversely affect the camera. Additionally, the fibreglass reinforced polycarbonate body with high-grade steel chassis offers the necessary robustness to meet the challenges of demanding daily use.

K-7:
With 77 weather seals in the body and 43 in the optional battery grip, the K-7 is fully moisture, dust and cold resistant. Whether shooting in a hot, humid forest or in freezing temperatures (down to 14 degrees F, -10 degrees C) on a mountain top, the K-7 will continue to perform. Offering the highest level of weather protection in its class, the K-7 is the perfect DSLR body for use in any environment - at home, in the studio, or when traveling where conditions are unpredictable.
The sealing in the K200 is as good as that of the K20D or K-7. They are all air tight enough that sand can't get in them. The only difference with the K-7 (Per JohnCPentax) is that its seals are rated for lower temperature. So the claim of improved durability at least in terms of weather with the K-7 is in the colder temps it remains sealed.

Not even the 645D is sealed better, they are all as good or sealed as good as Pentax could. If you realized how every seem, button, dial, has at least and usually more than one seal, and how through Pentax was you would feel very confident. Its not cheap and quite a feature we may be taking for granted. Pentax owners should feel proud about how well sealed they are

Quote for K-7
"the K-7 features 77 dustproof, weather-resistant seals applied to different parts of its body to completely shut out foreign substances. In addition, the optional D-BG4 Battery Grip features the same reliable construction, completing a highly airtight photographic tool unaffected by rain, sand and dust."

K-7 : Digital SLR Cameras : PENTAX

Quote for K20D and K200D in Pentax USA brochure.
"
Protection From The Elements
Whether you’re shooting in a misty, tropical rain forest,
on a snowcapped peak, or along a dusty desert trail, the
seals around the durable PENTAX DSLR bodies reliably
protect the inner components against humidity, moisture
and dust particles. The fiber-reinforced polycarbonate
body surrounding the high-rigidity, stainless steel chassis
provides plenty of strength for every day use.
A complete system: the K20D is protected by 72 seals
and the optional battery grip with an additional 38 seals,
while the K200D has 60 seals in the body and 14 in the
grip, assuring complete protection against humidity, dust
or sand. PENTAX offers the highest level of protection in
either class. Durable and solid: the stainless-steel chassis
is also impermeable to corrosion and is extremely stable"

http://www.pentaximaging.com/support/manuals-and-literature/

Quote from Pentax Japan same source as the K-7

"Dust-proof, water-resistant, airtight body performs superbly under demanding conditions
There are some rare and spectacular scenes that you can capture only in the rain, sand, dust or extreme humidity. The K20D boasts a dependable dust-proof, water-resistant construction comparable to top-grade professional models. A total of 72 special seals are applied to different parts of the camera body, including the control buttons and dials and the seams between different exterior components, to prevent the intrusion of foreign substances. Its superb reliability and durability under harsh conditions have been proven through a series of uncompromising performance tests and strict quality inspections.
Optional battery grip assures the same dust-proof, water-resistance performance
Mounted to the bottom of the K20D, the optional D-BG2 Battery Grip features the same dust-proof, water-resistant construction featuring 38 special seals. When paired with the K20D camera body, they form a seamless, airtight imaging system."

K20D : Digital SLR Cameras : PENTAX

As far as toughness I will have to say Pentax did not build the K-7 weaker, but stronger than any before. But if your standing in rain for 8 hours, the same seals protect the K200 and K20D and basically the same for the K-7 although they retain their 'softness' in lower temps and sealing ability. The amount of seals is because the K20D has more buttons and dials versus the K200 and as I said its take a number of seals just to seal one dial!

And last a quote from JohnCPentax
"The only reason the K-7 has more seals is to accomodate more buttons and openings."

K20D weather sealing vs K-7 weather sealing: Pentax SLR Talk Forum: Digital Photography Review

More reading...

And if your really interested in sealing. I bought the Kodak DC5000 10 years ago. It was a DC280 in an all weather tough body, and you paid a $300 premium for it. When looking at my first dSLR Pentax caught my eye (the K10D) for its toughness and WR. Anyways there has been industry standard and ratings for years, as to the level of protection an enclosure offers against water and sand. The Kodak DC5000 has a rating of IP54; and Kodak rated it to withstand drops of 3' on cement with no damage. This is a big (about K10D with 50mm prime lens) heavy camera!!! I still use it. You can find the meaning in the links below. There are two ratings, one made in Japan (JIS) and one in Europe (IP). Pentax was asked why it did not rate their dSLRs (JIS rating) as Olympus does and gave an answer in an interview with the K10D designer; second link below.

Yeah, I guessed the K200D was sealed as tight as the K20D and K-7, and the only reason there were less seals etc was due to less buttons and so on on the K200D that needed sealing, relative to the K20D and K-7.

That's why I am holding onto my K200D. It's nice to have an all-weather body and lens combo at hand, especially in the sub-tropical zone in which I reside.

Not to be negative or anything...I am a K-7 user myself....when Pentax said the camera is weather resistant, i have always been curious to know why have Pentax not declared an international IP rating for the body.....

If they say the body is dust resistant (not dust proof) and protected against water (not waterproof), i would say they should at least declare the body as IP54.

But the fact that they have not declared such rating is either they don't think the normal end users will notice/mind or they don't think the camera is really that dust/water resistant.

What do you guys think?

Edit: I read the pentax blog but i just could not understand why is it not possible to apply the JIS rating to the body? They can always say that the JIS rating can only be achieved when paired with the DA* or WR lenses?

That's a good idea for a niche market. Either just test it and market it with the rating, or do some simple(?) modifications and release an IP54 EX certified camera - for the industries that need that, the price is usually not that important.

That's exactly what i am thinking.

I mean, if i am buying a external light fitting and it is declared an IP65 rating, I have the confidence to say that water will not enter the body during heavy rain (not submerged in water). If I am buying an IP44 fitting and i bought the fitting with the full knowledge of its IP rating, i will be kidding myself if i say the fitting is "weather resistant" as it is not.

I totally do not mind if Pentax just declared the K-7 as IP54 rated when only paired with its own DA* lenses....at least i know where i stand when it comes to using the camera in the open. I know what to expect from my camera gear. People who buy the camera will in fact have more confidence when they know the IP rating (even thought it may not be rated as high as they would want to).

By not declaring an IP rating (perhaps there are other difficulties in the camera industry we do not know about....prolly some legal issues as well) and simply calling the body WR is "a bit" misleading IMHO.

I have every confidence in my Pentax gear. I can totally understand why Pentax haven't given there cameras a IP or JIS rating because of difficulties with the moving parts and having to rate all the '*' and 'WR' lenses to the same standard. Giving a camera a IP54 rating isn't really relevant because Pentax would be inundated with complaints about dirty sensors.

With all the SDM failures, I'm scared to get a drop of water on my 50-135 let alone get it soaked in the rain.

Sometimes I wonder if the golden goose-feather filled pillow I put it on at night is enough to keep it safe...
