"The other aspect is the build quality. It may be a “Contemporary” lens but there’s nothing cheapish about it. The lens body is made of metal. The ginormous, rubberized focus ring is super smooth. It’s almost too big when trying to get a handle on the lens for mounting/unmounting. Sigma’s statement regarding the degree of sealing is a bit fuzzy. They are referring to a sealed lens mount but this leaves a question mark regarding the focus ring at least. The lens does not extend during focusing so that’s certainly positive when it comes to surviving in harsher environments. A petal-shaped hood is part of the package."
