Weather Sealing for Canon Products

John Gifford , Jul 11, 2006; 08:37 a.m.

Hi everyone,

I'm considering jumping into the Canon side of things and I understand that the EOS 1 film camera incorporates some 70 gaskets and seals to help seal it from dust and water. I also read that the L series telephoto lenses, 300mm f2.8 and larger, incorporate this weather sealing.

Do all L series lenses offer weather sealing? Or is it only the longer telephotos?

Also, which camera models offer the weather sealing? Do any digital SLR models offer this?

Thanks for your help.

John

Not all Ls are weather-sealed, and some require a filter on the end to complete the "seal". Here's a list that should be accurate as of January 2006.

Of current models, only the "1"-series digital SLRs purport to be weather sealed. Some claim that the EOS-3 (film) is weather sealed; I don't believe it is as much as the EOS 1 cameras, but perhaps moreso than most other cameras. I've used my EOS-3 in light rain and snow without any problems, and if I needed to shoot in a downpour, I'd certainly use my EOS-3 over my 5D, partly because if it turned out NOT to be weather sealed at all, it'd be much cheaper to replace. :-)

Michael Reichmann shoots in some pretty wet and dusty conditions and he has an interesting take on weather sealing in his 5D Field Report. Scroll down to where he compares the 5D to the 1Ds2. I think his comments would apply to the 20D and 30D as well.

Thanks so much, guys, for the helpful responses. Appreciate it.

The EOS-3 has sealing, but not as protective, and robust as the series 1's. You'll find this also documented on Canon's internet site.

I would never use my 5D in even light rain. Too often you'll read here and in other forums of those that use their 10D/20D/30D/5D's in rain and report back that there are no problems. To do this is to tempt the god's of disaster. Well, when it comes to electronics and water, often the damage does not become evident for days, weeks or even months. Corrosion can take time.

Some also thing that using a sealed L lens with a NON-sealed body means the lens is protected. It is not. It is only protected if the body is ALSO sealed.

I've used my 1D Mark II in very heavy down pours several times, with it mated to a sealed L lens and months later no problems.

To illustrate this feature to a friend, I once held my 1D Mark II mated to a 70-200L lens under a full blast bathroom shower head (probably 10+ gallons per minute) to his amazement. I rotated the body w/lens in all angles trying showing no way water would seep in.

He thought I was nuts. The truth is, the 1 series are nearly bullet proof bricks, true commercial grade kit.

Now that I only have 5D's I am much more mindful of this type of "abuse"...especially around salt water.

Dan, what a great story that is! I'm glad it came out in your favor, or else your friend would be the one telling it, I guess. =-)

Glad to know these Canon bodies and lenses are so waterproof. I know what you mean about the damage taking time. I've ruined good cameras simply from being around saltwater; never actually dunking the camera. Months later, the damage took its toll and the cameras stopped working.

I am very interested in the Canon EOS-1 35mm film camera, and the L glass, for this very reason.

I've only heard of that a few times. On the contrary, I use my 10D in light rain without hesitation. Snow, too. I've never had a problem.

"Some claim that the EOS-3 (film) is weather sealed; I don't believe it is as much as the EOS 1 cameras, but perhaps moreso than most other cameras."

According to the EOS 3 brochure, the body sports water and dust seals and is build to the same durability and sealing specs as the EOS 1N. For example, all buttons and dials use rubber gaskets to block out water droplets. The back door has a seal as well. Important electrical contacts are bipolar and gold plated. However the 1V and 1D series do the water and dust seals one level better.

PuppyFace, we've gone through this already...according to Canon's own web-site, the EOS-3 is in fact NOT sealed as robustly as the 1 series.

Sure it's sealed, but NOT as extreme as the series 1.
