I have an opptunity to buy Ilford Pan-F b&w film 35mm 100Ft rolls in a good price. I have just checked the price in New York area. B&H, Focus camera and Calumet are already out of stock for this film. Both Adorama and Unique are asking $40 a roll. Usually this film should be in around $30 per roll when it is available. The good thing is if I buy a lot I can get around $15 a roll. The problem is those films are dated 2005. I wonder if Pan-F (ISO 50) can be kept for a few years in cold storage and still usable, and if (the price wise) it is a good deal. The reason I choose to stock Ilford film is, clearly, Ilford b&w film division is not in a good shape and is for sale. The reason I choose to get Pan-f is because it is the current slowest traditional b&w film in the market. Slow films are always the first one on film industry's discontinue/kill list when there is any profit related issue (think about Ilford!). Even there is no profit concerns slow films are always the targets for upgrading to a higher ISO speed . On B&W side we already saw Agfa APX25 and recently Kodak TechPan as examples of being discontinued. On color side there are too many. Kodak Royal Gold 25, Kodak Ektar 25, and Konica Impresa 50 were killed a while ago. Agfa Ultra 50 and recently Fuji Velvia 50 are all went into history because of the "upgrade". Correction: Pan-F 50 is the slowest B&W film in Big 5: Kodak, Fujifilm, Ilford, Agfa, and Konica. Velvia 50 is not discontinued yet but could be soon if 100F is widely accepted.
