I purchased a used Canon T90 a little over a year ago. I have been using
it for all of my IR work instead of my older K1000 (never had the dimpling
problem with that one either). The only fogging that I have had was the
day that I couldn't get the film loaded when I was out on a shoot, and
had to just open the back and load the film under a tree. Lost the first
five shots. Other than that....which was my fault, I don't have any
problems with IR in the T90. Should I knock on wood?
