Cinestill produces a tungsten film (the 800T) based on motion picture cinema film; they pre-process and package the film so it can be used in 35mm cameras and processed in any C41 capable lab. Cinestill also had a daylight film and planed to offer a 120 format film, but if I believe their web site (http://cinestillfilm.com/) all products are sold out at the moment and the kick-starter project for the 120 format did not get off the ground.
You can however still buy some film in some online re-sellers or in brick and mortar shops. I have 5 in my house in France waiting for me that I ordered from Firstcall Photographic Ltd in the UK and I bought this one in the Lomo shop in Chinatown in Singapore. This is quite a costly film, Lomo sold it around 16 SGD and Firstcall 13 (so around 8 EUR or 10 USD). Processing is standard price so around 8 SGD here. All in all this is quite expensive for casual shooting.
Picking the camera to try a new or special film is a bit tricky, I do not want to blame the gear for missing shots or bad exposure, so I decided to remove the dust from the F4s. Unfortunately it appeared (once all loaded) that the auto-focus was not working any more. Well we have a say in France that for every bad thing there is a good one coming. So with no AF working I was allowed to pick up a manual lens; that was the small and sturdy 50mm F1.4 AIS. But I must admit it feels silly to carry such a big beast of a camera with no AF.
After google-ing a bit I decided to overexpose the film a bit and shot it at 640 ISO and processed at 800. This is a Tungsten film, for those who do not know it is to be shot in scenes lightened by tungsten bulbs. Daylight shots should be done with a 85B color filter; I have done none of this and tried to manage the white balance in Lightroom, but I think I’ll get the proper filter next time (quite inexpensive).
