I have the 8-16L. You can slip filters in on the back end of the lens. a pain in the behind, but works. I've used gelatin ND filters and will experiment with gel IR filters. cool thing about the gel is its way cheaper than the glass.

Did you find R72 gel IR filters? I have been looking for a long time, but only rather expensive ones are sold (like 100$).

FYI - you can correct most of the distortion in LR4, if you shoot around 14mm and use the old canon fisheye lens profile correction....

I bought wratten gel filters from B&H...specifically no. 87 and no. 89b. One throws a more red hue and the other a more blue hue. I've read both are pretty decent...only used them once - to test if they worked. They do. I also picked up wratten ND 2.0 gel filters. I stack two of the 2.0 filters to help me get longer exposures.

Sorry I took so long to get back here. Time is tight....

yes, but it seems the 89b (r72) is not available anymore.
