Blackmagic Pocket Cinema Camera 4K

The assumption I was questioning is if there is a equal relationship between shooting two stops lower and actaually loosing the same number of stops of dynamic range.  The post stated that shooting at ISO 100 and you will loose 2 stops of DR.  Tests will show if this is actually the case... also because of the lower noise floor st  lower ISOs you could underexpose a bit and bring it back in post, which would compensate for loosing some dr/headroom in the highlights.

Yeah, but now you are just doing what would happen if you exposed at (let's say) 400 normally, instead of 100. Between ISO 100-800 no gain is applied by the sensor, only the curve is shifted. In raw this doesn't matter, because you CAN underexpose at ISO 100 and just apply the 400 curve without losing anything. However, due to the compression applied by prores (which is pretty good, don't get me wrong), you'll likely have less shadow detail/more noise when you pull up ISO 100 in post to match ISO 400 as opposed to just having shot at ISO 400 to begin with.

I would guess at this point anything not coming from Blackmagic is clickbait fakes. Preorders have undoubtedly gobbled up the first few months of production, perhaps longer. They're going to sell them as fast as they can crank them out for awhile. The P4k certainly doesn't need a blogger junket like the EOS-R to convince people to buy, it looks flat out amazing.

The video taken at the Seoul Zoo wasn't uploaded by BMD but was confirmed legitimate by BMD and the person who filmed it took a picture of the Pocket 4K setup that they used.

That is the assumption but why no mention in the specs and why the low data rates in the specs?

They aren't low, those are the standard bit rates of ProRes at those resolutions and frame rates. The bit rates are all listed in megabytes per second not megabits. I think they didn't specify because I guess ProRes is usually at least 10-bit and probably because no Blackmagic camera has ever recorded in 8-bit so they may have wrongfully assumed that everyone knew already.

I'm keen to know if the Ronin S can control the focus of the P4K. Does anyone know? 

I love the proof of authenticity at the end of that clip, hilarious... but what about this? Tried too hard to rescue the sky in post?
