i have been using expired film for 3 years now. no problem at all. i use slide, color, and B&W. i have used slide film that was 3 years old with no problems. i just got a whole boat load of 16 year old 4x5 film the other day. the tri x, t max and the kodak 64 E6 are all fine!!!! i can not believe it myself! (oh! and they were NOT properly stored! they came out of a garage in upstage NY!) i also have some 8x10 that came with this that i have yet to test. i am assuming they are fine too! enjoy shooting expired film. it sure save alot. i also deal with collect888.com. all his stuff works beautifully! maybe i should stop telling everyone this.....that would leave more film for me! lol!
