There are many casual reviews (probably due to the amateur market the camera is targeting) but they aren't hired by Fuji. Fuji just loaned a lot of cameras with some free films to get customer feedback, and perhaps as a marketing channel as well, but to my knowledge they took back the cameras and only some of the testers bought their own cameras. So there are lots of web sites that clearly state their dissatisfaction (considering the price).

But so what, when you care about such, you'd better carry a medium format camera with a separate meter anyway. If not, buy two Natura S and load one with a slow film... it's still just as cheap as an extra film back for some MF cameras... (not that I'm saying that the camera is cheap)
