Latest Review Posted | Sigma DC Macro OS HSM 17-70mm F2.8-4 When I first got the lens a few years ago (K10 era), I wasn't mega impressed with it. The reviews were saying it was supposed to be really good. It was ok at f-8 and higher, but wider than this I didn't rate it at all and it ended up as a backup lens. It also didn't like the cold - it failed on top of a mountain in Norway :(. I dropped my 18-135WR so had to return that to Pentax and finally got round to sending the Sigma back to Sigma UK (who sent it back to Sigma Japan) as it now had a fault on it. What I got back was the same glass and case, but a completely different lens. Pin sharp. Really, really sharp. Really impressed with what Sigma Japan have done with the lens. I'm quite happy to use it as my main lens at the moment - its a shame its not weather sealed like the 18-135. I like the idea of it being f2.8 at the wide end and can live with the f4 at the 70mm. |
