New Sigma 17-50mm for Pentax

No optical stabilization = cheaper price?

By PF Staff in Deals and Savings on Dec 5, 2011

Sigma has recently announced a new version of the Sigma 17-50mm F2.8 EX DC OS HSM for Pentax (and Sony) which will only differ from the old version in that the Optical Stabilization (OS) module has been removed. Since all current Pentax DSLRs feature in-body Shake Reduction, the OS system was more or less redundant, as it's certainly not better than in-body SR at short focal lengths.

Thus, we expect the price of this lens (which is currently $669) to fall slightly once the new version is released. The new version will be marketed as "Sigma 17-50mm F2.8 EX DC HSM" and will be optically-identical to the current version.
