I attribute it to the fact that the film gate is not perfectly flush with the film -- since the 15mm will sit closer to the film plane than any of my other lenses, it follows that the light rays reach the corners of the film plane with a more extreme angle. So, they can "sneak" under the film gate and make the image size larger than 24x36mm (or whatever the actual film gate size is, I haven't measured it).
