Are any of the Canon EF-S zoom lenses weather sealed?

Hi Henry, I have owned the 15-85 and I used it in a large variety of dusty circumstances and can tell you now that it will inhale dust!

I know have the 24-70 f4 L and have just returned from another dusty envoirnment only to discover that it has also inhaled dust!

i think most of these zooms that extend when zooming will inhale dust regardless of weather sealing.

I just ignore dust now as it doesn't seem to affect iq.

Just to clarify, there is dust being sucked inside the lens, or just on the rear element?

That's correct Henry, the dust is being sucked inside the lens.

I am very surprised at that. Was it much dust that was sucked in? Could it perhaps be from dust on the mirror / sensor left over from a lens change?

I wouldn't have thought it would come from a lens change! But I could not be 100% positive.

I am fairly sure that it's related to lens design that allows very fine dust particles to penetrate the lens.

my 70-200 however has no internal dust visible (internal zoom) and this lens has also had use in dusty envoirenments.

Perhaps the 24-70 f/2.8 II sealing is more efficient.  Anyway, the f/2.8 is way more then my current budget allows.  I think what I might end up doing at this point is buying a cheap, used 50D with kit lens to use when the dusty conditions have high chance of damaging the main camera.  That way I dint have to worry too much about costly repair / cleaning bills!
