What can expect from Sony at Photokina 2018 ? Sony currently has no new camera codes registered, so we may not see any new Sony cameras (a7S III, a6700, a77 III, RX1R III) within next 1-2 months. But we may see some new FE lenses around this Photokina.
According to latest rumors, next Sony FE lens will be Sony FE 24mm f/1.4 GM lens, to be announced around Photokina 2018 in September.
Polish website Optyczne recently paid a visit to Sony Japan, and had an interview with Sony managers from Sony Japan. According to the interview, Sony currently is developing longer telephoto full frame E-mount mirrorless lenses in the near future. As rumored before, Sony may release FE 135mm lens and FE 400mm lens in 2018.
According to a new source from SAR, Sony will announce two new FE lenses next: the Sony FE 20mm f/2.8 Lens and Sony FE 135mm f/2 Lens.
