Hi!

 

I'm adapting some old lenses (mainly oct-18) to the PL mount, and some of them have quite long rear part... 

 

Is there somewhere exact dimensional drawings or information, how much the rear part of the lenses can protrude inside the PL mount 

in certain camera models before it touches the internal filters or other parts, eg. how much there is free space inside the mount? 

The manuals seem to have only the image plane marked, not where the filters actually are...

 

Main cameras of interest are: 

 

Red Epic 

Red One 

Arri Alexa 

Arri Alexa Studio 

Sony F3 

Sony F5 & 55 

 

thank you very much for answering  :lol:

If they worked with a spinning mirror reflex camera they will work wilt all the above. The optimo DP range won't work on film cameras but will work with the above except possibly the Alexa Studio, however there will be a problem with the new Red Motion Mount.

Should be fine on anything but the Studio, where you need to be careful of the mirror shutter. Angenieux Optimo DPs for example won't fit that one, but will clear the other cameras mentioned. 

 

Here's a drawing of maximum allowable lens protrusions for the Alexa Studio:
