Hi everybody, I'm doing a check out tomorrow and we are checking two 24mm lenses, one of which is detuned, what does that mean?

Thank you in advance for the help!

I believe it's a term Panavision invented, where they deliberately degrade the performance of a lens by adding optics or altering some settings.

Dom is correct, this article here with lens guru Dan Sasaki goes into a bit more detail - http://www.panavisio...cal-engineering

 

 

How do you “tune” your Panavision lenses? 

It depends. Many times we ask for a still photo or example of what they would like to see. Based on the example or description the Cinematographer gives us, we can start determining methods to “customize” a lens. It usually takes a couple of iterations before we match the cinematographer’s expectations. The method of detuning is constantly evolving and we are continuously trying to innovate new ways to create a unique look. 

An example would be non-coated lenses. Originally, we would remove the coating off lenses. We found this was an unnecessary and destructive method of achieving a look. Now, we have found a way to produce the same look without having to destroy the lens and have better control over the degree of effect and unwanted glare. 

Were Panavision lenses originally designed for this kind of adjustability? 

Every case is a unique challenge. Very rarely are we asked to duplicate a detuning scenario.
