you are not going to push anything 6 stops as in the example here. Dynamic range instead is more important if you move the camera and can’t control the light. Anyway I guess you bought this camera and now want to be happy so be it

I find this comes into play more often than not in post, when in want to pull or push the image. If that’s backwards so be it… but that’s where I need the flexibility.

What a poor result. -.-

A camera with less dynamic range clips sooner that is why dynamic range is important. If you expose properly latitude is in fact less important. So I guess you got it the other way around

Sensor measurements show that the A9III has noise reduction on sensor baked in at all ISO level

Funny, I’ve not found exposure latitude to be non-useful. I find it useful all the time in post. And FYI: if your camera is clipped, dynamic range will not save you… clipped is clipped. There is no data to recover. Best to expose correctly in the first place.

Sorry but this is practically irrelevant. 9 stops of latitude are non useful if you camera clipped and the delta on DR is two stops. For sure the stabilisation is useful if you shoot outdoors handheld however those are the scenarios that will make the camera clip and latitude will not help you. You can use tools to stabilise the image but nothing is a proxy when your footage clips.
Tip I have a mac Studio 64 GB noise reduction is still painfull and delays the workflow on 4K

The A1 beats this in resolution. It does not beat the A9 III in exposure latitude… which is what you need when you get in post and wish to recover details in the shadows or highlights. The A1 does not best the A9 III in stabilization… not in camera, and certainly not in post; where the global shutter shines as there is no jello effect to deal with. It fulfills the promise of the Red Komodo’s global shutter, but with a more streamlined workflow.
There are also numerous ergonomic advantages that simply make the A9 III easier to work with. The A1 is only a first pick if resolution is your primary concern.

Pro tip: If adding noise reduction is painful, you may need to upgrade your computer.
