which one do you guys recommend?
89B? or 87?
the 87 is like the hoya r72 in every way, if you're gonna get it then get the hoya because it's half as expensive (I think)
89B is pure infrared. if you're rockin a 20d, don't bother. d70 can handle it though. The 20d has a pretty strong hotmirror filter that will take out 99% of the infrared that your expensive filter would let in
I'm using a Konica Minolta Maxxum 7D. How can I test if it has a strong hotmirror filter also?
use a tv remote in the dark :tup:
