My wife and I have a MeetUp group called Charm City DSLR Film Makers. See us in Baltimore, NYC, DC, and of course Los Angeles.
If the anamorphic is mounted with a lens support you would have to use lenses with internal focus otherwise the lens would push against the anamorphic when it focused right?
Don't forget about the new per node caching in resolve as well. U can add a noise reduction on the first node cache it and work the clip without all the demoiselles overhead
Should you have moved the camera more to see the fixed pattern noise? Thats where you can really see it. I'll test my camera tonight
