Sometime early this month, I had the opportunity to purchase a very slightly used, 4-month old Sigma 28-70mm f2.8 EX DG. But before I bought the lens, I did some research in the Net for opinions, reviews and photos taken by this lens.
Well the reviews and opinions about the lens coming from Pentax users just weren't encouraging. Yet, users of this lens from other systems were much more positive and upbeat. Apparently, there are very few Pentax users of this lens, with most advising to get the Tamron 28-75.
However, I just couldn't let go of the good deal I was getting, so I decided to take the leap and purchase the lens, all the negative feedback notwithstanding. Well, I don't regret my decision! The lens may show some softness at f2.8 of 70mm, but other than that, it is sharp in all apertures and ranges. The colors are great (Sigma-wise), contrasty, with DOF really narrow - great for portraitures.
For those thinking of looking into this '05/'06 lens series, here are some of my shots.
