The same sources whom shared all the correct info about Sigma lenses confirmed that Sigma has decided to postpone the 70-200mm f/2.8 FE lens launch to autumn 2020. One of the sources says the reason has to do with Sigma trying to improve the autofocus algorithm. This works very good on prime lenses but is said to not be flawless on zoom lenses. They need time to improve it.
