New Sigma 70-300 OS lens
This is a very reliable information, but unfortunately I do not have more details. I guess this new lens would be a replacement of the current Sigma 70-300mm f/4-5.6 DG APO Macro telephoto zoom lens and will add OS (Optical Stabilizer) function. This lens could be announced next week (maybe even on Monday).
The pictured lens is the current model.
