>>3644124here's a chart of the flagship monstro sensor
but take it with a grain of salt, it's from some random dude on a red user forum using an unlicensed version of imatest and whatnot, but yeah you won't see any legit third party measurements so anecdotal evidence and these kind of amateurish or at best in-house measurements of a rental are the best thing we'll get
you can see that it spits out a tad more DR than an alexa and the overall distribution of noise is very similar, but the blue channel is super noisy in comparison which doesn't matter in some situations but break others
I'd say if you downsize the 8k image in post then there's a lot of usable information in it, even a noticable bit more than in the alexa
but other than that it's very similar and clearly they're trying to hide that by claiming all kinds of dynamic range out there
which everyone does of course, but red is clearly the worst offender
