Hello everyone!

 

I have a Beaulieu 4008 ZM that I plan on doing a lot of shooting with. It has the Angenieux 8-64mm lens. I picked up a light meter. It’s a Gossen Luna Pro that has a “cine” scale.

 

The manual is here:

The film is 200ASA, and I can easily set the light meter to 200.

 

After pressing the Range Selector, I have a reading of “12 1/2” on the scale, and I adjust the ring so the yellow triangle is at 12 ½.

 

At 24FPS it appears to be f2.8.

 

What I’m not taking into account is shutter speed. How do I figure out shutter speed in relation to f stop for this lens and camera combo? Should I be a stop above or below f2.8?

 

Am I on the right track?

 

Thanks!

 

Chris

I believe that camera has a 1/86th shutter speed, not the typical 1/48.

The 4008-series has a variable shutter with a 100° opening angle, operated by the topside lever. As Chris believes, the shutter speed is indeed between 1/7 sec when set at 2 fps, and 1/86  at 24 fps and 1/87 at 25 fps. You can get a manual for the 4008 ZM specifically as a PDF download by clicking here, and an overview of operations in comparison to the other top Super 8 cameras as download in this post here in our Super 8 forum's FAQ.
