Master List of Weatherproofed Lenses

I did some searching here on POTN and Google see if I could come up with a master list of all weatherproof/sealed lenses.

All I got was what Canon's site gave me:

Compatibile Models:
EF 300mm f/2.8L IS USM
EF 400mm f/2.8L IS USM
EF 500mm f/4L IS USM
EF 600mm f/4L IS USM
EF 400mm f/4 DO IS USM
EF 16-35mm f/2.8L USM
EF 24-70mm f/2.8L USM
EF 70-200mm f/2.8L IS USM
Extender EF 1.4x II
Extender EF 2x II
EF 28-300mm f/3.5-5.6L IS USM
+EF 17-40 f/4L
+EF 24-105 f/4L

I know there has to be more to the list than what Canon provides, so I'm hoping you guys could fill in the gaps.

I also had a few questions
1) I'm extremely paranoid about dust. Even thought I know that a few dust specs inside the lens will definately not affect IQ, I just can't feel comfortable knowing it's inside. I was hoping a weather sealed body could give me a better chance at avoiding dust. So the question comes down to: Is it worth having a sealed lens but an "un-sealed" body? I could put up with wiping down the sensor once in a blue moon, but sending off lenses to canon for a wipe down seems like a headache.

2) I raise this question also on behalf of a future purchase of either the 70-200 f/2.8L IS which is definately weather sealed OR the 70-200 f/2.8L (non-IS) which, as far as I can tell, is not sealed. I'm wondering if weather sealing + IS is worth the extra $650 or so. (Or would you rather spend that $650 on a 17-40 or maybe a 580ex flash unit, etc)

EDIT*: Added some to list

17-40 is missing,

There is a complete list in a thread here.

is the 24-105 weather sealed???
i thought all L lenses were?

Yes it is, and not all L's are weather sealed. there is a small rubber gasket around the mount, if its there, it is

OK I got atleast one weather sealed the
How abt 100-400L aka dust sucker ?

Nope

hmm, Ok so it can eat dust. Dust, beware & stay away else you gonan be sucked or eaten

I love mine, dust eating and all

I never got dust in either of mine. That "dust sucker" talk is just rubbish. It's a darn fine lens, and even if it did get a few specks in it, it wouldn't affect IQ any. Gotta say, though...Mine were super clean, and I used that sucker (npi) every single day.

Junior. Think about it. you are increasing the internal volume of a container (the inside of the 100-400 lens) by zooming. YES, really sorry but it does suck in outside air. that means the contaminants in the air too. now way to avoid.

Name a lens out there that doesn't alter the volume of one or more of the chambers as it zooms/focusses, thus drawing in air from the rest of the world. The only ones I'd consider "safe" using that criterion would be the lenses for a Nikonos, or a fixed-focus P&S.

any zoom lens will suck dust if you push/pull or twist it fast enough...

its just that it's easier/faster to work the mechanism on the 100-400... and get that "pumping action" going down

As dante said you're increasing the volume inside the barrel.....and that air has to come from somewhere.........
you would think that some kinda air vent with an air filter would be the order of the day... (should be easy too impliment something like that into the design)

Good points. I would think internal focus/internal zoom systems such as the 17-40 and the 70-200's will have a less of an induction effect as opposed to regular systems such as the 24-70 or even the supposed vacuum devices i.e. 100-400

Are you sure about that? (Rhetorical question)
Most canon Ls do not change length when zooming like the "linear zoom" action of the 100-400.
24-105 and 100-400 being the only dust suckers in the L range.

and the 24-70, 80-200, 100-300, and more, I'm sure. That said, thinking about the 24-105, why did they make that barrel extend anyway? With the retarded hood design, it doesn't need to. Seems like it should have been IF.
