yes, select the camera, or create a new one (create>cameras>camera) , and open the attribute editor.......... go to the camera attributes tabby thing in the Attribute Editor.......... set Focal length to 15... and Angle of view to 100.3... that should work or you can set the Focal Length to less, to make the effect more Exagerated

and what maya doesnt offer, you can script easily in MEL or make a plugin in c or c++ (which is really easy as well, the plugging in part, cuz the graphics programming is a piece of hard crap)

For additional effect you could use mental ray with a lens distortion shader. There's one in Puppet's shaders_p pack here: http://puppet.cgtalk.ru/download/shaders_p_e.shtml

Like any other lens shader. Here's an old tut about the DOF shader. You should be able to adapt it to the fisheye shader.

thanks allot. without proper rendering your image is never complete huh i mean a good model with no proper texture and no proper render is as good as a crappy model.

Follow the instructions in the readme.txt. Basically you copy the files to the right places and edit the maya.rayrc file and that's it...
