I am working on a shot, and am having trouble getting the distortion to work. Here is a link to the footage. http://www.istockphoto.com/file_closeup/recreation/sports/ski_mountaineering/3004092_ascending_mountain_top.php?id=3004092 I don't know how to calculate without any straight lines in the scene, and am very new to lens distortion in general. could anyone give me some guidance.

There's lots of information on distortion in the manual. In short, click the "Calculate Distortion" box before you solve. THen when you render your CG, redistort it using the same coefficient.

I was reading about distortion before I started this topic, and I read that you can add a lensShader in Maya to distort your cg as well, but it never said which lensShader to use. I also noticed you could export your distortion as a Mesh OBJ in Syntheyes. Can anyone give me some guidance on how to fix distortion this way for future reference on other projects.
