is this lens weather/dust proofed?

The lens is weather sealed with gaskets at the lens/camera body interface, and along all of barrels for focus and focal length. I've had rain poured on it, and the camera had no problems. I would not immerse it in water, but rain and dust should not be a problem for the lens.

The Canon EF 24-70mm f/2.8L II USM Lens has a "Tight seal structure [that] ensures excellent dustproof and drip-proof performance" (owner's manual). You are going to want a protective filter on this lens to fully seal the area between the front elements and the lens barrel.

I could be wrong but I believe that all Canon L category lenses are moderately dust/water resistant (not proof) from the factory.

No, none of the currently available lenses are. Some of the new lenses Fuji will release later this year are going to be weather resistant.

I don't know if they are "rain proof" but they are certainly "rain resistant." They seem to be sealed very well and there is a rain shield on the top of the camera. It will slide out to shield the lens from stray raindrops. I tried to mount my cameras where they would be protected from direct rain.

Have had the lens for a while now....It's been in some pretty dusty places - Including a few National Parks as well as the Beach. Never really experienced the "Dust Problem." Great little lens that delivers beautiful photos. Great walkabout lens for my 60D. Saving for the 70D as we speak.

Hi, The best info you can find is here at the BHPhoto site: http://www.bhphotovideo.com/c/product/842934-REG/Olympus_V204045BU000_OM_D_E_M5_Micro_Four.html . As you can see Olympus advertises a dust proof and splash proof system on their micro 4/3 cameras and Zuiko lenses. I would always suggest you verify with the perspective seller that the lens is the genuine OEM M.Zuiko lens. It most likely is (seems to be a package that Olympus sellers like to offer) but it doesn't hurt to verify this. As to water touching any camera equipment: Unless it is made to be submerged under water I would never trust my equipment in the rain and would immediately cover it up with clothing or my body. After all, if you're going to spend a Grand on photo equipment you need to plan to treat it with some level of respect when it comes to the weather IMHO.

I don't rmember what the warrenty was. Rain has been no problem. it even fell over and got muddy and worked just fine . droplets on the lens may mess up some of the vidio/pics.i've had mine since spring of 2013

The lens is clear. I've talked with Cooper customer service about the cracking lenses. I was told that some of the lenses, if not milled exactly to specs, can crack. She was very helpful and sent me a replacement light. Hopefully the problem with the lenses has been solved.

My occupation requires that I crawl attics and crawl spaces. I have had mine in some pretty nasty attics and there is no dust behind the lens. I wipe it off with a damp cloth. Hope this helps.

I put mine in that locking box which I think protected it some from weather but I am sure it got wet without insult. Sometimes the lens was affected by water droplets but that is not a malfunction. As for cold, I think it ran out of juice faster in cold weather, a problem solved with lithium batteries albeit an expensive option.

If screwed in properly it should help keep any moisture and dust off of your camera lens....I have not noticed any problems with my lens an this time.

Yes, it is weather sealed/water resistant. Like C. Finchum said, you do need to pair it with weather sealed lenses in order for this to still be true. Pentax makes a variety of weather sealed and non weather sealed lenses.

I cannot know which set you are looking at. The lens should be designated by Pentax with the letters WR on the lens for you to know that it is weather resistant. Good luck with your shopping.

It is not weatherproof like camera's intended for external use are. Power connection is not waterproof, and no hood to protect the lens from sun glare. I would not recommend.

No, none of the Fuji lenses are weather sealed at this time. Only one of their cameras the XT-1 is weather sealed.

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.

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.

The lens is exposed but there is adequate protection. I've had the case for over a month and my lens is still perfect. I hope this helps.
