Back in 2016 Samyang launched their first FE autofocus lenses. They were the 14mm f/2.8 and the 50mm f/1.4. Today they launched this teaser for an early November announcement. It says this lens is “re-born of the 1st Samyang AF”. From the silhoutte this surely looks like a new version of their 50mm f/1.4 FE lens.
