I recently upgraded to 11.5 and I can't seem to get depth of field to work. I've made sure that DOF is checked, set the focal distance and messed with the f-stop settings. I've tried Mitchell and other settings... classic to perspective...

I cannot seem to get the same effect I used to get with 11.0

I've used the same settings from 11.0, but the depth of field just doesn't seem to be there anymore.

Anybody else run across this?
