Originally posted by SpecialK Note the lens is the DC version, though the database shows the DC EX version. Also, B&H says DC EX (clearly not) and once it's in the cart, also say HSM (clearly not). The DC EX HSM version is $439 at Adorama, however.
Yup, there's some listing errors in the description of the Pentax version on pretty much every site. What I've read though (I can't remember which thread) is that Sigma never made the HSM version for Pentax.
This lens will be loud, Oh well.
For the record, I bought one because of this sale.
