Anamorphic - step rings

[Salvador M. Rodrigues]

Hi everyone,

 

I'm relative new to film and recently I became interested in the anamorphic concept. I own a 16mm bolex camera and a beaullieu super 8. I have recently bought a Kowa 8z anamorphic lens but I'm not really sure on how to attach it to other lenses.

 

The kowa seems to have a 49mm thread, now my zoom lenses that came with the bolex and beaullieu have a higher thread. My kern switar c-mount lenses have a much lower diameter and thus lower thread. How can I attach the kowa ? Do I need a special mount adaptor or can I use step rings ?

 

For the zoom lenses, I can see the step ring working, except what happens when the anamorphic is smaller than the zoom ? I would surely get a vignette ?

 

Thanks for any clarification!
