So I am starting to see the limitation of my Walkaround Lens and am starting to look at alternatives, and find a pair of lenses that could each fill the role with faster glass… and then start looking at the details (Because we all know the devil is in the details)
So I am looking at
Sigma Lens 17-50mm f/2.8 EX DC OS HSM for $879
Sigma Lens 18-50mm F/2.8 EX DC Macro for $541
So… What in this case does OS & HSM amount to, how does it (And all of the other available initials) effect me in real terms.
For $338 it is worth knowing.
