I ordered 5 boxes of Ilford panchromatic film and received 5 boxes of film (4 boxes of the panchro I ordered and 1 box of SFX200). Oh well, I was a little disappointed at first that I didn't get my full 5 boxes of panchro, but after some research, I discovered the SFX200 is an infrared sensitive film. Having just sent one of my digital cameras in for a full spectrum conversion, I'm actually intrigued to shoot this 200 speed film now. I didn't even realize Ilford made this film. So, I'll chock this up to a happy accident in my book being introduced to this film unintentionally. If I like the results, it could lead to more experimentation with this film stock.
