Samyang is the latest new entry but there are two more curiosities:
- Surely not many of you knew that Fujifilm actually is E-mount partner! Imagine they would start doing FujiFilm X-PRO and FujiFilm X-T Full Frame E-mount cameras. That would be amazing or not? I know…it’s not going to happen :)
- No Chinese company is an official partner. And this is weird knowing how many of them are releasing excellent and interesting lenses!
