Are any of Sigma's lenses sealed?

[NTB]

Just wondering...I recently purchased a K20D, which is sealed, and I plan on trading up to the K-7 eventually. Just waiting for the price to drop Both of these bodies are sealed, but the 2 lenses I have right now - the 18-55 kit lens and the 55-300 are not. So weather-resistant lenses are something I'd like to look into, as well. And yes, I know they're expensive So, does anybody know?

Nope, none of Sigma's or Tamron's are sealed. This is partly why going for a fully weathersealed system is so expensive... locks you out of third party lenses
