Well, given the situation with Kodak, I had asked Fuji Austria about their professional films, as it seems that the 400H is now the only option available in 135 format. The answer is sobering:
135 format negative films currently available:
Superia 135/200-36 single and x3
Superia 135/400/36 x3
Superia 135/800-36
Superia 135/1600-36
We no longer stock the rest of the range due to a lack of demand. We will also soon be discontinuing 800 and 1600 films.
It is unclear exactly what this means (I have followed up again regarding Acros and 400H and am awaiting a reply), which is why I have spent a long time considering whether I should share this response with you at all. Perhaps it is only Fuji Austria and their own distribution warehouse; the statements do not necessarily mean that the other products are no longer available globally or across Europe, but the response is certainly not reassuring.
On a positive note, however, I would like to mention that Fuji Austria replied within two working days – no one at Kodak Austria made any effort to answer my enquiry a few months ago, when rumours about the discontinuation of transparency films were doing the rounds.
