what can be expected that this kind of lens "WR" or a camera WR like K50 would resist? Rain? sea water drops? dust? humidity?

WR stands for "weather resistant." It is resistant to mist, rain, dust, etc., but not submersion in water. Read about it. Start with http://www.pentaxforums.com/reviews/hd-pentax-da-55-300mm/introduction.html.

I use this lens, the 55-300 wr a lot in mist and light rain, severe wind with sand blowing around, ice storm, etc. It comes in handy. Of course with the grit in the wind I keep a protective filter over the lens. And in Texas our weather is humid all the time.

Not sure I can be of much help.....I haven't tested all of the "elements" that you listed as threats to the lens - really haven't experienced extreme conditions under rain or sea water spray - some, but nothing severe. Living in Oklahoma I know my lens is exposed to dust. All I can say is that there is no apparent affect on my lens or camera to this point...but then both are still relatively new. I trust Pentax to perform as promised. My K30 is my "fourth generation" of Pentax - Spotmatic, ME Super, Super Program, K30.

Here are a few of my favorite shots, mostly from the Amazon trip. https://www.flickr.com/photos/51739634@N08/sets/72157651296722820/All the Amazon pictures were taken with my K-30. I've since added the K-3 and have a few samples from that camera as well.

I used this lens on my K30 during a 9 day trip in the Amazon, encountering mist and some rain with no issues. The build construction and image quality are excellent for the price. The main downside is the noisy screwdrive autofocus. It's a trade off, but I am happy with this lens.

I use it on the North Shore of O'ahu for surfing pics. It is perhaps the most widely used lens there. Works great in sunny conditions, but tends to struggle when it's overcast as it is only an F5.6. If you plan on using it for indoor sports, it is not "good". It is OK at best.

The lens itself does not have any rubber gaskets to keep out water and dust. At its closest focusing distance, there is a gap between the first element and the mount where you can see the electronic chip so put the focus somewhere in the middle during storage so nothing gets inside the lens. I've personally used it in the snow and got it pretty wet(heh) but all in all it was ok when I got home. It should be fine for usage in moderately dusty places.

This kit does not come with a weather sealed lens. Only the WR lenses are water resistant. That's why this bundle is significantly cheaper than those that come with WR-lenses.

In terribly humid climates I would hope your camera is weather sealed. This product prevents wet weather from dropping on to your camera but has opening for your hands so allows the air (humid or not) in. It would certainly keep the outside of your camera nice and dry.

Pentax basic kit doesn't come with water resistent lens. I suggest you check before buy the camera. DA 18-55 WR is water resistent.

WR here stands for Weather Resistant. DA L, AL (Digital Era, Analog Era) Lenses. WR lenses are little more rugged and can handle rougher usage. I had dropped one of the lenses from a good height and was lucky that it didnt crack or scratch. I just dusted it and started clicking again. I also saw a video on youtube where a user placed his pentax camera in sand (hiding and covering it in sand). He took pictures and then cleaned the camera and lenses under running water from a tap. He mentioned he was using WR lenses, so that was pretty impressive.

Please be noticed that this kind of Lens filters is intended to protect your valuable camera lens against scratches and similar physical damage. Considering this, I don't think this filter may work as a Water-Resistant protection. Therefore, if you plan to use your digital camera pretty close to liquids/humid weather conditions (rain, waterfalls, fountains, etc.) the best protection you may get is using a camera rain cover.

Don't expose it to rain. Doesn't get cold here so not sure about that. Under eves might be OK. Some rain on lens OK but might leave residue. Power supply not approved for outdoors, so at your own risk.

I have not paid any attention to the warranty conditions. Water resistant? ..... I live in the Puget Sound area and have left the camera out in the rain for as much as four days at a time with no problem.

Well, I used mine in the rain on a tripod pointed at a bird feeder. We got a MAJOR rain (historic flooding) and my camera died. Returning for warranty service; I'll cross my fingers that Bushnell will replace it.

The lens on my camera never fogs. I used the camera all day long under and above the water. The only time had some water drips on the lens and I did not notice and few pictures came little bit unclear. If the underwater feature fail I believe you can still use as a normal camera. Hope this help you

With reasonable care I think it should be fine. I used the lens on a 3 week safari in Tanzania in dusty, sometimes wet conditions and had no problems. I kept it covered in a lightweight stuff sack when not in use.

I haven't had any problems with rain or water from my cooler getting on it, but some other reviewers said water would get on the inside of the lens but personally I have not had that problem yet.

I only see one lens listed here Michael, the DA 18-55mm f/3.5-5.6 AL which is Weather Resistant [WR on lens]. It is a superb zoom lens for the cost. Certainly an excellent choice whilst saving for a more remarkable lens in the the Pentax line. The camera's cost is itself is outstanding, as the K-5 will continue to amaze with each new lens. Note: If you already own some fine Pentax optics you might consider exchanging the value of the "kit" lens for a battery grip!

I bought the Pentax K-30 with a lens Pentax DA 18-135mm f/3.5-5.6 ED AL (IF) DC WR, which is weather resistant to handle damp, inclement conditions
