The good news just keeps coming with this film. Fujifilm claims Provia 400F can be pushed 3.5 stops with reasonably good results. Well, that's going to depend on how you define 'reasonable'. Pushed one stop to EI 800, this film continues to shine. Grain increases slightly and contrast decreases slightly, but color saturation remains very good. In this respect, Provia 400F really becomes a problem solver because now I can shoot hand-held indoors with f/2 and f/2.8 lenses. Although I haven't tried, I probably wouldn't push this film two stops unless there were absolutely no other options because image quality is likely to degrade significantly. Fujifilm's claim of push capabilities to 3.5 stops is hard to imagine.
Die Entwicklung des 400X erfolgt im E6-Prozess für Diafilme.
Der Fujifilm Provia 400X wurde 2013 eingestellt und befindet sich deshalb nicht mehr in Produktion.
Es gab den Provia 400X für Kleinbild- und Mittelformatkameras.

When I first thought of using an ISO400 slide film, Fujifilm Provia 400X was a natural choice given how fond I am of Fujifilm Velvia 50 and Provia 100F. If anything, I sort of expected Provia 400X to be quite similar to Provia 100F, only two stops faster. Having used Provia 400X for a number of years, however, I have always felt that its colour reproduction is quite different from any other Fujifilm transparency. Recently I went again to —a small, nice island not far from Shanghai—and, as the light was not exciting enough for exhilarating landscape photography, I decided to use the opportunity to compare the two Provias.
It is worth noting that the Fujifilm Provia 400X has been the company’s single high-speed slide film for a while now, so this is a very sad day for photographers looking to take advantage of high-speed photography on film.
