Frank,

It has nothing to do with film or the brand of filter. The problem is  
the color response of the filter at extreme angles. If you take an IR/ 
UV filter in your hand. Look through it straight on. The color  
through the filter is quite normal. Then slowly rotate the filter so  
you are looking through it at an angle. The color through the filter  
will turn cyan. The sharper the angle, the more cyan.
