Help with Lens change Acti ACM-4200 - Computar T3Z3510 CS-IR

[britchie911 0]

The Computar T3Z3510 CS-IR lens I have is definitely a CS type, but its threads are too short to reach the threads on the Acti ACM-4200 after stock lens is removed.

 

Any Ideas on what I am doing wrong? Others on the forum have posted success with this combo and say the ACM-4200 uses CS lens type.

 

Thanks.

Hello? Anyone have a suggestion or idea?

 

Acti tech support confirmed the camera is a CS mount.

 

Interestingly. When I called the Computar distributor they asked for photo's of the lens (showing two sets of threads, silver & black).

 

The info received back was an incorrect spacer was on the lens i received. They sent out second one ASAP. I received the new lens today and it is the same config. I'm being told the silver piece/spacer "should" come off (counterclockwise thread) but I haven't been able to get it loose and don't want to break it.

 

There are three philips screws at this end, anyone know if they need to come out?

 

So much for standards. HELP!!

 

Thanks Brad
