Red Lenses - Why not T stop

[Mark Williams]

It seems inconcievable that todays top lenses would not have t stops marked on them.

Hi Stephen,

 

Yes, Cooke individually calibrates, marks and engraves the scales on all of

our lenses. However, I believe this is not the case for all lens manufacturers!

Hope things are going well for you.

 

All the Best

Well there you go. I read on the Zellan web site that they custom scaled their footage rings, but it didn't say anything about the aperture. That was for the primes, there was no mention of the zooms.

 

Thanks,
