Appears to have been very little on this lens here so far so thought I would share my impressions after a couple of days of ownership. I've owned the Sigma 100-300 f4 for several years but always felt it needed that bit more reach and could really do with OS (I've tried it with the 1.4x converter but never really been happy with the results).
So been keeping a careful eye on reviews/postings concerning the new bigma with OS and finally took the plunge earlier this week. On the basis of a coulpe of hundred images shot over the last two days I would say this lens is pretty amazing given the price and the zoom range. I was concerned abou the f6.3 max aperture but providing you're shooting in half decent light then I don't think it'll be a problem. The autofocus appears to be a huge improvement on the 100-300 which I always found had trouble locking, particularly on birds in flight. The few attempts I've made so far seemed to indicate a much better success ratio than with the old lens.
It is quite weighty, no getting away from that, but then I don't think high quality glass comes in light weight.
I've posted a coulpe of shots on the gallery of a Coot and a Mute Swan as starters, may post some more in the near future when I get the chance.
