Hmm, I thought this was one film that was still available easily. I have a 120 pack of it, must stock some more of it. I honestly think they need to remove the word "film" from their name . Fujiinstax is perhaps more apt these days LOL!
Not sure if it is still available in other countries but it's no longer listed on the Fujifilm UK website although it may still be available in stores until they have used up their stock.
As far as I know all Fuji Rangefinder 645 cameras shoot in portrait mode as standard with the need to change the orientation for landscape, which is the opposite of 135 film cameras. Having got used to this I often now shoot landscapes in portrait mode when using 35mm cameras, perhaps as much as 40% of the time
