Originally posted by mokey Can anyone tell me if there is any optical difference between these 2 lenses? Is it just the OS? I'm looking at the Sigma 70-200 f2.8 EX DG APO OS HSM ($1400) and the Sigma 70-200 f2.8 II EX DG APO Macro HSM ($950) Reviews are confusing on these 2, as the macro seems to have slow focus - not what I need for sports pics. Any help would be great! Thx
The OS version is the newer one, and I think it has a slightly revised optical formula (apparently better) as well as the addition of the OS system.
Sigma has had a number of 70-200s over the years, and to the best of my knowledge, these are the revisions of the lens, in chronological order:
- Sigma 70-200mm F2.8 EX APO
- Sigma 70-200mm F2.8 EX DG
- Sigma 70-200mm F2.8 EX DG Macro HSM
- Sigma 70-200mm F2.8 EX DG Macro II HSM
- Sigma 70-200mm F2.8 EX DG OS HSM
The last two are the ones you're looking at.
