According to a recent interview with Zeiss’s managers by iLHP at PhotoPlus 2015. Zeiss currently is working on 5 more Full frame E-mount lenses for a7 series mirrorless cameras. In 2016, we can expect Zeiss to release 2 or 3 of these lenses.
From the interview:
There are obviously some secrets that they have to keep as the industrial competition is always ongoing but they could let us know that we can expect about 5 new Full-Frame E-mount lenses, including 2 to 3 new ones in 2016.
Zeiss also said they are working on current two Zeiss Batis lenses, to reduce the waiting time as quickly as possible. Two new Zeiss Batis lenses are out of stock everywhere, you can get overpriced Batis Lenses at eBay US.
