I may sound a bit odd to ask this question at the time when Fuji just announced discontinuation of many films, but still - here it is: Would you be interested in the Provia 400X in large formats? (4x5 or even bigger?) If yes or no - why? Currently the only ISO 400 film available in 4x5 is Kodak 400NC. Reportedly 400X responds rather well when pushed to ISO 800 - 1600. I found myself preferring slides to negatives and sometimes to get 2 more stops helps to reduce the wind or impact of the subject movement. So my answer is - YES - it would be my main slide film for 4x5. The grain is fine enough for large prints even form smaller formats and color palette compares very well to Provia 100F. so - what is your opinion?
