Dear Otoy, why Octane features are so poorly documented especially new features? There is only one sentence describing some parameters.
eg.

Coma - Rays hitting the lens edge have a larger field of view.

Do we have to guess what this does?

In comparison, please take a look at vray manual:

For some optical characteristics it's going to be hard to describe without diving into physics.
For this particular one, just paraphrasing, it does distort rays in such a way that the periphery of the lens is acting like a lens with a larger field of view. There is not much more to say about it. This distortion is gradually stronger towards the periphery. Wikipedia says this: "coma is defined as a variation in magnification over the entrance pupil.". Or, maybe more concretely, "This causes an image that is not in the center of the field to appear as wedge-shaped." (Not sure if that helps much though…) https://en.wikipedia.org/wiki/Coma_(optics%29

I and probably most users don't need detailed technical documentation. What we need is an updated manual with examples how to use new features without guessing what given parameter does.
