What exactly does "WR" mean?

So WR can withstand "heavy sunshine"? So I gather a Fuji non-WR rated lens should not even be used outside where it might encounter "heavy sunshine"?
That was of course tongue-in-cheek, only to point out that I personally don't pay any attention to a manufacturer's claims about what a camera can withstand when the claims are not backed up by the warranty.

I still use a bag for my camera to protect it from water. It's not hard nor cumbersome. But then again, it's not described as 'weather-proof'
 
Leica X-U

The X-U (Typ 113) features a tough, rugged construction that is designed to withstand harsh climates and underwater shooting:
  • Waterproof to depths of 49' / 15m for up to 60 minutes of shooting (IP68-compliant)
  • Shockproof to falls from 4' / 1.2m high (MIL-STD 810G, method 516.52-compliant)
  • Dustproof to protect the internal components of the camera
  • Anti-slip rubber exterior for improved grip in wet conditions
  • Integrated UW protective glass filter guards the front element.
= WR

I'm actually tempted...

Yep, I feel the pain. But it's cheap compared to the SL, which I also wish that I could afford.
 
I understand and some common sense is helpful, but I wish there was something more definitive than some vague guess between high humidity and complete emersion. You hear horror stories about someone having catastrophic failure after somone breathed on a camera while another person swears they routinely snorkle with the same model camera.

It is an NFL term.

WR is what Fuji says it is, just note how they phrase it.

For example, for the XF 16mm F1.4:

"The weather-resistant structure features 9 seals in 8 areas on the lens barrel. These keep the lens protected from sudden rain, dust and splashes of water."

http://www.fujifilm.com/products/digital_cameras/x/fujinon_lens_xf16mmf14_r_wr/features/

For the XF 18-135mm:

"A weather resistant structure with applied sealing on 20 areas on the lens barrel is tough against various changes that occur in a natural environment, such as sudden rain, dust, and splashes of water."

So, one can conclude it should resist "changes", e.g. sudden splashes of water or intense rain and dust events but no guarantees are made that it will resist the entire thunderstorm or dust storm for hours.

I have a Bulova watch that is listed in the catalog for 20 meters, but says in the printed sheet that came with it not for swimming. The tech rep that I got on the phone said that a twenty meter listing is OK for doing dishes, but for swimming I need a 100 meter listing. I explained that I am doing the crawl on the surface of the pool. He repeated that I shouldn't swim with it.

I'll rely on the link to the lens rental article listed in this thread and not on advertising hype.

I am certainly not going to purposely take my expensive WR listed camera out in the rain. Too bad. I thought I could.
 
Sorry, the link that I referred to was on the other WR thread. Here it is:

 
There are some things to consider here. How do you folks clean your gear? Do you use some sort of cleaning agent? This can have an effect of how resitent your gear is to water as many cleaning agents have additives to reduce waters surface tension. If there are traces of such a cleaning agent on your gear water can not form drops and smears out and can more easily penetrate your camera or lens. Actually the fat your fingers leave on the surface might be your best protection against water. Maybe you have seen that strange machine at your favourite bar that doesn't seem to do anything else than rinsing the beer glasses. That's a very important machine, without it you won't get a beer with that nice fluffy foam on top of it.
 
Hi,

I'm wondering which of these things (for example) someone could do without worrying about damaging the Fujifilm X-T1 and WR lens:
Fuji's idea is:

Protection against "various changes that occur in a natural environment, such as sudden rain, dust, and splashes of water" and reliability in "tough weather"

Note the emphasis on "changes" and "sudden" meaning the equipment should be fine getting caught in rain or some splash from a waterfall but may not resist the entire shower without user action.
* take a few pictures in a light rain before coming inside
fine
* take a few pictures in a downpour before coming inside
fine
* set camera on a tripod for an hour in a light rain
fine

This is not even tough weather and it takes a long time for light rain to equal a splash of water.
* set camera on tripod for an hour in a steady rain

* set camera on tripod in a thunderstorm for an hour

* leave camera on tripod all night on a stormy night
not fine - this is tough weather but not the brief exposure Fuji is describing.
Also, how is it possible to make a zoom lens waterproof? I would think that no matter what some moisture would get in the lens when you zoom.
Fuji does not suggest that you can also keep on zooming. You are supposed to limit exposure to adverse conditions but not worry too much in case something happens.

Water is slowed down by the sealing. If you splash it, then wipe it dry, the seals will dry up before something enters. If seals are kept wet on the outside, something will eventually seep through them. The condition of the sealing materials probably deteriorates with age.
 
Slightly off-topic but relevant to the LensRental story, I actually recently broke the metal rear bayonet mount off my 18-55. This happened by dropping my X-T1 with lens attached ~4' onto concrete. I don't think the lens actually hit the ground, I think the side of the camera did and the weight of the lens popped the rear mount partially off.

Two of the screws were no longer holding the metal lens mount to the body, so I removed the others and took it off. I can confirm that the metal lens mount is held on by screws attached to plastic. However, it appears the Fuji has embedded small brass retainers into the plastic. In my case these had been pulled out of the plastic, which had also broken on two of the screws.
 
About an hour shooting in constant rain with no cover - lighter overall than in the video although it did get that heavy at times. Camera is still working just fine. (Note that I did use a lens hood, I'm not sure what that guy thought would happen in not using one.)
