7D weather seal. Canon says...

Michael Young , Feb 23, 2010; 02:58 a.m.

Having not found any indication of what, precisely, Canon and reviewers might mean about the 7D's weather resistance and improved seals, I finally asked Canon directly. Here's what they wrote in response:

Thank you for your inquiry about the weather seals on the EOS 7D. We
value you as a Canon customer and appreciate the opportunity to assist
you.

The 7D is not a weather sealed camera. It should not under any
circumstance get wet. It may survive some rain, however, there are no
guarantees. If you need a camera with weather seals you should look
into our EOS 1 series cameras.

To clarify, none of our cameras or lenses should be immersed under
water. The EOS 1 series cameras and certain L series lenses do offer
weather seals. These seals do not make the equipment water resistant or
water proof. You should always try to keep the equipment dry.

For the conditions you described (hard rain, under a shower, and being
immersed), you should be looking into an underwater housing. There are
several third party companies that offer underwater housings for our
cameras.

Now, are these weather seals, or placebo seals? Maybe my mistake was mentioning warranty in the question.

None of the Canon cameras are warrantied for water or environmental damage. None of the Canon cameras are tested to any of the international standards for weather resistance. Absent a warranty or testing to international standards, you can pretty much assume that these things should be treated with care.

In other words, no one (Canon included) knows exactly how weatherproof each model is, so when you play in the water and dust, you should probably use protection of some sort.

http://www.canon-europe.com/cpn_eos7d/ - click on page 14. "In terms of weather sealing, the EOS 7D features the same level of weather resistance as the old EOS-1N film camera."

(link) - "The EOS 7D features a magnesium alloy body that is dust- and weather-resistant..."

http://www.dpreview.com/previews/canoneos7d/page4.asp - note the diagrams which dpreview.com got from Canon.

Whoever responded either a) isn't familiar with Canon's own literature, or b) wants to avoid potential warranty liability.

There are few guaranties in life. But yes the 7D has improved dust and moisture resistance over previous XXD models. However, no Canon camera is water and dust proof and and no language indicating water or dust damage is indicated or implied in the warranty. If you get it wet, you're on your own.

Robin Sibson , Feb 23, 2010; 05:19 a.m.

It's certainly the case that neither Canon DSLRs nor, AFAIK, any DSLR from any other manufacturer, is given any formal rating of the kind found on electrical equipment designed to be used under wet conditions.

Now, perhaps this is just a "false memory", and if so someone will surely correct me, but I seem to remember an EOS-1V advert all those years ago showing the camera half-in and half-out of a rock pool. Not that I would have tried it at home.

Michael Young , Feb 23, 2010; 06:02 a.m.

Now hold on. I wasn't particularly incensed to read his response, and I'm not bucking to be consumer's advocate to the supreme court. But here's what Canon says on their website about the 7D's weather and dust seals:

The EOS 7D is constructed of the highest quality materials, to exacting standards to ensure unfettered performance at all times. For example, the shutter can shoot at speeds up to 1/8000 sec. for 150,000 cycles; the chassis is built of lightweight and rigid magnesium, and the camera's seals are built to resist water and dust . This combination makes the EOS 7D ready for anything .

(link)

Contrast that with the customer service response: " The 7D is not a weather sealed camera. It should not under any circumstance get wet. ... If you need a camera with weather seals you should look into our EOS 1 series cameras. "

OK. Fine. It has water seals, but I should not under any circumstances get it wet. Help me out then. What do these sentences together mean? I wouldn't know an implied warranty if I sat on one, but there is in fact a bald statement that by virtue of the 7D's materials, construction, and seals, it is ready for anything. I take that to mean it is ready for anything and continue to be a 7D, which has some further implications beyond simply the metaphysical.

Maybe if we start simple, and work our way to the tough one. Simply because they say it has dust seals, I wouldn't stuff it in a bucket of floor sweepings and continue working as though nothing had happened. I wouldn't put it in the sandblaster and test its readiness for anything (implying everything?).

There will always be a difference in marketing puffery versus engineering savvy. That's just the way it is.

Lester Wareham , Feb 23, 2010; 07:24 a.m.

The fact is even the 1 series cameras are only moderatly sealed as these things go.
Note the reference marketing material states "resistant to water and dust", not "weather proof" etc. AFAIK Canon are very careful about that wording. Most often the phrase is "dust and drip proof", which to my mind is a bit strong.
I have a web page with more contextet on so called weather proofing you might find informative http://www.zen20934.zen.co.uk/photography/Weather%20Protection.htm

You have a rock pool at home Robin? ;)

Exactly.

Happy shooting,

No, only a pond, and freshwater woudn't count, otherwise of course I would have tried it!
