How "dust proof" is your E5?

This is about wheather sealing and warranty from a French photographer with his Canon 1D MKIV.
How relevant is this for an Olympus user or the OP? Again, you quoted the OP who is discussing Olympus and bring up Canon. Can you actually read?

This is just more brand bashing BS.
Your hypocrisy astounds me.
How come? Isn't this the Oly forum? What has that stupid story got to do with Olympus? Why divert the attention from Olympus to Canon? Isn't that what FUD is all about?

Fear, uncertainty and doubt.

Fear
that another brand may be better, or at least as good.
Uncertainty about the future.
Doubt about the quality.

Pointing to where someone is worse is not a proof of Olympus quality, just childish brand bashing, nothing else.
 
Of course not. Do people go diving with the E5 without a special housing? But, just to be clear, I'm not saying the 5D has any sealing anywhere near that of the E5. I'm just saying that I've used it in heavy rain and snow. Was I worried about the camera failing? Sure. But I did it anyway.
Given the 7D problems -- where some people have acted on information from others that it is weather sealed then got themselves a dead camera -- I wouldn't risk exposing the 5D to rain.
I rarely do -- it's not often I see a scene in the rain that's worth shooting. And, despite the fact that I always use a hood on my lens, water drops on the FE (especially for wides) can be an issue, in terms of getting a "good" pic, in heavier rain. But, sometimes, it's worth the risk.
i dont see other cameras underwater in swimming pools without protection, hot pools in Iceland, half frozen from a user here, never seen it.
So you've not seen it. And?
It should be obvious.
I'll discuss "should be obvious" a bit further below.
You shouldn't confuse what the warranty covers with what the actual capability is .
I don't -- ergo I'll take my 5D in the rain and snow.
Remember that Olympus demonstrate the capability at trade shows.

High-end bodies and lenses are often sealed, and usually quite well. From user reports it appears that no comparable system exceeds the Olympus system in this capability.
Well, "user reports" also tell us how horrible the corners of FF, since some users are expecting sharp corners wide open, for whatever reason.

But, yes, I completely agree that the E5 has excellent ruggedness. The question, however, is how it compares to cameras such as the K5, D300, D700, etc., and how that translates in practical terms.

For example, let's say the E5 can survive, on average, for 10 minutes submerged 1m under water whereas the K5 can only make it 8 minutes. What conclusion would we make of this in practical terms for people who don't leave their camera 1m under water for any length of time? Would it imply that the E5 will last longer under severe conditions? I don't think so.
(We can't be sure that a Nikon D3 or Canon 1D with a suitable lens wouldn't also survive a dip into a thermal pool, or routine rinsing off in a shower, due to lack of such reports. Certainly press photographers always seem to use rain hoods on such equipment, but that may be prudence rather than a lack of faith.)
As I said above, there is the issue of the quality of your photos with water all over the front element.

But, yes, this brings up "what should be obvious". The fact that we've seen the E5 take some abuse and not seen other cameras subjected to the same abuse speaks no more to the superiority of the E5's weather resistance than it speaks to the superiority of the intelligence, or financial sense, of those who didn't do the same with other brand cameras.
But Ive seen Olympus gear in that situation and have every faith in it, especially with a modicum of care and a minimisation of risk
The OP, apparently, had the same faith. Unfortunately, he got unlucky.
Given the options seem to be misfortune or misuse it seems more likely that misfortune was the cause.
Either way, he was unlucky. The fact that his E5 failed and was not covered under warranty does not speak badly for the E5.
He should have queried the finding, in any case. A manufacturer does not have to prove grounds for dismissing a warranty claim, AFAIK, but it never hurts to explain your use and ask for a suggestion as to how the sand may have appeared. If they decide that you aren't a "problem customer" they may revisit the decision. An over-zealous / just plain wrong technician may be the real problem in this case.
As has been brought up before, regardless of what the warranty says, or does not say, I've not seen any controlled systematic testing of various cameras to make a conclusion about which is more rugged than the other.

There's no doubt that the E5 is excellent in this regard, and I've not seen anyone deny it. However, to say it's better than cameras such as the K5, D300, etc., well, I've not seen any evidence one way or another.

But, let's say it is better. Is it "enough better" to where it has any practical relevance? That is, if someone were deciding to get an E5 or K5, would the differences in weather protection play any role in their decision, even given that they used their camera in harsh enviroments?
 
BTW, the 12-60 has a nifty two-stage tube assembly that has larger, visible, gaps where the guide slots are -- the rear element extends forward much further. I guess we could get "very small rocks"* into an E-5 using the 12-60. :)

(* Where the definition of very small rocks would be something like 0.2 mm diameter.)
Actually, sand can be much smaller than that...

http://en.wikipedia.org/wiki/Sand
Well, if it's in wikipedia then it must be correct. ;)
If you have better source, please feel free to share. Also, if Wikipedia is wrong, please edit and correct it. Anyway, it is surely a better source of information than this thread…
It's also not just "very small rocks".
Sand is typically any small particles with a "gritty" texture. They can't be too fine or you won't notice the texture.
What's the definition of "too small"?
Regardless of what you call the material, it has to be small to have any chance of getting through the 12-60 mechanism, and smaller still for the 50-200. I haven't checked out all of my lenses, so there may be some that offer a larger gap.
Of course it must be smaller than the whole it is passing through :) but I don't know what makes the 50-200 harder to pass through other than the length of the lens. All it takes is more time. Anyway, the 12-60 is an SWD lens but the OP is talking about the old 50-200 (I assume) and that is totally different from the SWD. It is also older and assuming it is worn out, not as tight as the 12-60 or any new lens.
I take it that Nikon lenses have large gaps, thus the misplaced concern from Nikon users in this thread? :)
Sure. One beautiful day I found this in my image:





It's NOT a 100% crop, just a resized image, so that thing is huge, so my lenses must have huge wholes... It's that, or it got inside the camera while I changed lens whichever is more probable. Of course, we are talking about Nikon, so the first must be the true cause, huge gaps in my lenses. :p :p :p :p

Well, "user reports" also tell us how horrible the corners of FF, since some users are expecting sharp corners wide open, for whatever reason.
Not to mention low vignetting, absence of CA, and not having to stop down too far to reach optimum sharpness.

If only there was a system that offered lenses with such qualities -- preferably in an easy to understand hierarchy of some sort.
But, yes, I completely agree that the E5 has excellent ruggedness. The question, however, is how it compares to cameras such as the K5, D300, D700, etc., and how that translates in practical terms.
There is a lack of data. About the only thing we can say is that Olympus are willing to "abuse" their products while other manufacturers do not.
For example, let's say the E5 can survive, on average, for 10 minutes submerged 1m under water whereas the K5 can only make it 8 minutes. What conclusion would we make of this in practical terms for people who don't leave their camera 1m under water for any length of time? Would it imply that the E5 will last longer under severe conditions? I don't think so.
What if it turns out that the E-5 (and a lens, presumably) can survive an indefinite submergence of 0.5 m while the K5 begins leaking immediately?
(We can't be sure that a Nikon D3 or Canon 1D with a suitable lens wouldn't also survive a dip into a thermal pool, or routine rinsing off in a shower, due to lack of such reports. Certainly press photographers always seem to use rain hoods on such equipment, but that may be prudence rather than a lack of faith.)
As I said above, there is the issue of the quality of your photos with water all over the front element.
Those big Canon lenses have rather large hoods. I imagine that rain would have trouble getting to the front element in the usual conditions you see the gear being used.
But, yes, this brings up "what should be obvious". The fact that we've seen the E5 take some abuse and not seen other cameras subjected to the same abuse speaks no more to the superiority of the E5's weather resistance than it speaks to the superiority of the intelligence, or financial sense, of those who didn't do the same with other brand cameras.
Are you referring to those who may, for example, use a Canon 5D in rain or snow? (The 5D is, of course, a low-cost and non-sealed alternative to the 1D series for those not requiring those sort of features.)

:D
As has been brought up before, regardless of what the warranty says, or does not say, I've not seen any controlled systematic testing of various cameras to make a conclusion about which is more rugged than the other.
Nor are we likely to see such tests, given the expense involved in testing to failure.
There's no doubt that the E5 is excellent in this regard, and I've not seen anyone deny it.
You must be new here.
However, to say it's better than cameras such as the K5, D300, etc., well, I've not seen any evidence one way or another.

But, let's say it is better.
OK, let's. Evidence suggests it is certainly extremely good; but all equipment can fail, even under "normal" use.
Is it "enough better" to where it has any practical relevance? That is, if someone were deciding to get an E5 or K5, would the differences in weather protection play any role in their decision, even given that they used their camera in harsh enviroments?
If you had a requirement to use a system in inclement weather and use of "rain coats" etc was problematic then you should be evaluating the body plus lenses. AFAIK, only Olympus offers a weather-sealed body and two tiers of lenses. Pentax seems to be heading in the direction of a weather-sealed system, and Canon can offer that if you can afford the top-of-the-line body and lenses.

So I think that this is an area where Olympus do have an advantage. The problem, IMO, is that they only offer a weather-sealed E-x body. Many people would be happy with a weather-sealed E-xx body and putting the extra money toward another lens.

The FUD you are trying to spread is more to the point, as is your "brand-bashing" of Olympus.

What the warranty terms are is not relevant to the capabilities, and the capabilities are not relevant to this incident. The OP has a gripe about Olympus refusing a warranty repair because they claim to have found "sand" in his E-5, and he believes it didn't get there through his actions so it must be the E-5 to blame. Enter into the thread yourself and some other people who do not own the equipment, to posit ridiculous theories about said "sand" being sucked through lenses. Pure FUD and brand-based trolling.

WRT the 1D IV incident: lightbulb perhaps finds it surprising that a refusal for warranty repair somehow becomes an argument that "the E-5 is weather sealed, not water proof", "the lens may have sucked in sand" etc and wanted to know if the same type of argument applies to the much more expensive Canon 1D IV. Apparently not.

If I were to post on the Canon forum in reply to such an incident and point out that the 1D IV is "only weather-sealed" and that water is certain to find it's way in through the weather-sealed lens, what sort of reaction do you think I should expect? Gratitude?
 
i thought this whole argument came about because no one would believe there had been an equipment malfunction, and it was the OP mishandling lens changes causing all his woes.

its about warranty being refused due to sand being present in the camera

the synopsis Ive argued about mostly is that this sand found its way through a sealed lens into a sealed body. I think that to be operationally impossible. And besides, I dont see the OP recalling how he felt sand in the focus or zoom mechanism, or that he also found some residual sand in the lens

in the roundabouts way of illustrating objection to this scenario some of us have been discussing the waterproofness or otherwise of the lens/camera combo

just a thought but

what if the sand were already present in the camera from an earlier shoot, or that sand found its way from his clothing into the camera back at the hotel.

if anything is going to cause an environmental seal to go it's sand, and as you mentioned it could easily of happened at an earlier date creating the problem to occur much later, i know from experience of using underwater casings, getting a few grains of sand on the o rings can cause major problems.

From the lens (50-200) into the body. Only impossible if you never had this lens. It is very possible on the other hand if you do have this lens, and use zooming a lot. It is not just possible, it is guaranteed. If the lens got some particles into it while on or off the camera, this same particles will sooner or later be on the mirror, focusing screen, and eventually on where you do not want them to be - sensor. In fact, breathing the air as it does, I would not be surprised if it gets filled during the normal operation while on the camera. I had exactly the same experience with Nikon 18-200, at some point I started noticing tiny particles behind the front element. Which means I used it in a rather dusty and dry environment all summer long. I can not say I ever saw anything similar with 70-200/2.8. It does not expand, and I doubt there is any in and out air exchange from it.

  • first you would feel sand in either the focus or zoom mechanism, and there were reports of such things in the past. But the Op doesnt mention that
  • Then you have to count on the sand destroying the integrity of the aforementioned sealing within a relatively short time, and we arent just talking O rings. Perhaps, and only perhaps thats possible, but we arent talking minutes of operation, more like weeks or months in normal operation.
  • then you have to prove, that sand ingression beyond the destroyed focus or zoom ring sealing system can make its way from that point at the middle of the lens to the back of the lens beyond each and every lens element along the way.
  • and then beyond the lens (its sealed) and into the camera.
Those last two parts are what I find impossible, and a look at some of the sealed lens zoom mechanisms like the 12-60 (as it happens I dont have an image of a sectioned 50-200) I posted earlier confirms how impossible that is.

If the mechanism is on the way of the air flow.

Could be decades, if the lens is hardly used.
  • then you have to prove, that sand ingression beyond the destroyed focus or zoom ring sealing system can make its way from that point to the back of the lens beyond each lens element,
If it comes in through the ring, what if it does not?
  • and then beyond the lens (its sealed) and into the camera.
That's easy.

How about this image, what happens when the instrument expands? Where does the air go when it is pushed? Why is the expanding and contractnig lens different?

[SNIP]

Not interested in discussing Canon. If I was I'd go to Canon forum.

Yes, most probably most of what we get in our mirror chambers are coming through the lens opening while we are changing lenses, it is however ridicules BS to claim that Olympus gear can never fail.
 
im almost speechless

besides not answering my specific points that make it mechanically impossible to move sand through lens elements and out the back of the lens

how completely ridiculous

so Q?
is there residual sand INSIDE the lens

i'm not one to believe the rhetoric that Olympus or any equipment is 100% failproof, I've used both non olympus and Olympus cameras and seen phantom ghost specs on images during sequences.....something obviously got there that wasn't there before, hopefully mark will go back to Iceland and start zooming underwater.....wonder how long the camera will last then :)

I have a tiny particle on one of the inner elements on my 50-200, and it looks like it is stuck there. I know it was not there when I got the lens.

Just think about it, can you expand a completely sealed volume by twice its size? Can you compress it? So if there is an airflow, where do you think the air is coming from, and when compressed, where do you think it is all going to. Does the air get compressed by twice and just stays that way? That is the question.
