Blitz Defocus is a blinkscript-powered z-defocus node I wrote as I was struggling finding a tool that would simulate the bokeh streching and cat-eye occlusion happening on anamorphic and retro lenses. So I made one :)
It uses Jedypod's Optical Defocus algorithm so you can use real camera settings such as aperture, f-stop and focal.
Bokeh can then be squashed and cat-eye/barn-door occluded as they stray away from the optic center.
Some little extra features such as lens breathing, chromatic spread, bokeh noise and enhancements can also be found..
