It doesn’t mean 6k grades better than 8k from the same camera. JB Indeed! Hey, JB and I agree on something! While ratios can apply to anything, we all know that in the context of cameras they are almost exclusively used to refer to video encoding, so it's confusing at best, deceptive at worst, to use them to refer to sensors.

Storing Braw as 4:2:0 is brills, 4:2:2 would simply be a waste of data. There are already 50% more color samples than color photo sites using 4:2:0. Good Luck Nailed it, BRAW 12K stored as 4:2:0 from 50% more R,B sites, patent confirms this. That would equate to 6K 444, right? And what of 8K? 422?

Tom Roper wrote: an example of such I found here; a helpful and detailed dive into the human vision system that finishes with an ironic conclusion about how many "K" is needed for the human vision system, acuity seen from inches to yards, and what "the right number" for target "K" should be. "should be" is not a "scientific argument", because we're not talking about the acuity of the human eye, we're talking about cinema. And what's the ideal resolution of that? This guy doesn't know, and neither does anyone else, because there is none, "cinema" is not a surveillance camera or microscope w ..read more

What I meant is that a weak light builds up (flashlight in the analogy) somewhere in between your lens and the camera. When the light reaches a grey or dark area it becomes visible ( curtains closed in the analogy), when it falls on a bright part it will be hardly visible ( well lit room in the analogy). It’s clear that the phenomenon only shows up when there is enough contrast. My house has two windows facing south. I have a couple of different mft ada ..read more

John Brawley wrote: It’s more complex than wanting to use PV lenses Tim. They would have to agree to rent them to you. Typically they won’t rent you a lens package without also renting you a camera package. So PV have to choose to carry the Ursa Cine 65 and then do a mount conversion for it. I’m sure if there is demand they would consider it. But as of now you’re probably not going to be able to ring PV and ask for a kit of primo 70s by themselves to fit onto your camera. Or you’ll have to also rent some other camera from them that maybe you put to one side. JB Hmmm... that's a bummer ..read more
