Fuji X100S Press Release Leak
I'm not going to explain it because its all so fresh and new but I will summarize. This is truly an interesting niche camera. I thought the X100 was something. This promises to be holy batshit. I'm now looking forward to the X-Pro 1 successor as it seems like the X100 is the test bed for the flagship X mount cameras. Good Job Fuji.
FAST AF - fuji need this. apparently best in class, but we'll see if that claim is true
