The 127 Ysarex does not have huge coverage. You're out near the edge of the circle of illumination and seeing the effect of lens aberrations. Works to good effect, don't you think? It does lend a slightly creepy, threatening edge. Something's just not right here, but the viewer can't quite say why.
I know, my girl friend says that predator is in the tree. I did use some front rise and tilt to get the shot, so that explaines why the aberation only shows in this shot.
