Same here and I am tired of no one having anything to base their arguments on.

Yes, we are going to publish along side the MSED project we are hosting for Nathan.

Good. PM a link to that thread. The more people that do this kind of testing means more data, but we should all be "kinda" doing it the same way. Maybe I can learn from their mistakes when we build our rig.

You missed Kraps post on frame rate being a factor in this. It factors in a huge amount. Especially if you are shooting on prism based film camera and not digital (we will be filming on both)
