Many Schneider 0.95 lenses have a center or spot filter.

Version
CM 120: manual iris
CP 100: motorized iris (upon request)
CP 100 VF: motorized iris with spot filter
CP 100 VS: motorized iris with spot filter
and video signal control
So avoid the CP100 VF and VS versions, I had a 23/1.4 where the spot filter was impossible to remove, as far as I could tell, and also a 70/2.2 where upon disassembly the spot filter was on a separate film that could be removed.
