Weather Sealed Lenses

Which Canon lenses are weather sealed and to what degree can you expose them to moisture?

I've been entertaining the idea of picking up a used 1Ds Mk II and am curious which lenses will have the same weather sealed design? I own a few decent L lens now but don't know if any of them are weather sealed.

Cheers!

I think the 17-40mm F/4L is weather sealed when it has a filter on it. I don't know how effective the weather seal is though, whether it covers full on rain, or what. Be interested to know myself, I have one on the way

Weather sealing is not waterproofing. It keeps damp, and for me, more importantly, dust, out of the lens.
the 17-40 requires a filter to complete weather sealing, according to the instruction manual.

As my camera is not weather sealed, and neither am I, all I ask of my gear is that it won't explode if a few drops of rain get on it!

1dmkiin and a 300mm f2.8 l is
took 20 minuets of this with no weather cover

Looks like Zilly's gear is more than just shower proof - that's pretty darn wet!

The 70-200 f/4 is not weather proof, the 70-200 f/4 IS lens is . All the newer L lenses are weather proofed, some of the older ones are. Need to check each one before doing what Zilly did anyway! Remember only the 1-series bodies are weather proofed, so you need to bear that in mind if you are shooting anything else!

I wouldn't worry about a little bit of rain. I had a CPL mounted on my 17-40L which was on a 5D. Long story short...I slipped on some silt and dunked the entire rig in a knee-deep creek. Everything worked out fine...no water in the lens, in the body, or in the CF and battery compartments.

That's an encouraging example!

There's been so many rainy days this year where I would have otherwise gone out and done some shooting but was fearful of damaging my camera and lenses in the rain.

This is why I'm trying to figure out if what I have is adequate or if I need to specifically equip for rainy days?

Cheers!

The 70-200 f4 is not weather sealed.

I have a Think Tank Hydrophobia for my 400/2.8. It might handle weather as in the pic shown above but I won't do it. There are weather covers for smaller lenses available, I have a Storm Jacket for those.

Aquatech shields are the only real option a great peice of kit that will well out last even the most hardened of togs

I've used the Aquatech cover, no comparison to the Think Tank cover.

That looks to be a decently designed solution.

I don't shoot with long lens though. Mostly shorter focal lengths. Do these covers adapt to smaller lenses?

Cheers!

For the record, the 70-200 f/2.8 NON-IS is not weather sealed. Just the IS versions in the 70-2 family are weather sealed.

No Canon lens or camera is "weather sealed". That term is not used anywhere in Canon's documentation. The farthest Canon goes is saying that they have dust and waterproof "characteristics".

(Sorry, "weather sealed" is my biggest pet peeve term.)

Here is a list of Canon's dust and water resistant lenses:

Notice that the 70-200 f/4 IS is not on that list, although it is regularly stated as being D/W resistant.

Also, putting a filter on the lens does not "complete" the "weather sealing". If a lens is D/W resistant, it is without a filter attached.

Here is what Canon usually puts in lens manuals regarding filters:

Just means that the lens will be better protected, not that it is needed for any sealing effect. That was for the 17-40.

The manual for the sealed 70-200 f/2.8IS says nothing of using a filter.

Your link seems to provide the definitive list!

I guess this means none of my lenses are designed for the rain! ...oh well!

Cheers!
