I presume you mean to help with low tungsten light AF? An IR filter seems to have some effect: https://www.pentaxforums.com/forums/pentax-k-5-forum/129738-k-5-user-auto-foc...ml#post1382484.

I would bet he means the JPG processing option that makes the photo as if it was taken with IR film.

If that's the case, I tried it on the K7. Then I bought a modified K20d. If that isn't the case, then carry on..

Or if you meant with a dedicated IR filter fitted onto your lens, there are accounts of it here: K-5 and Infrared - PentaxForums.com

It does work and work quite well, I've been pleasantly surprised myself.

If its anything like my K10D and K7, you'll be happy with the results. Expect 30 second exposures at or around max aperture unless you go with a really high ISO. IR's pretty much useless in anything but bright sun though.

Here's a recent shot from the K7
