Nikon Zf: ISO 100 to ISO 51200 with AI Denoise (Color Card)
Firmware version 1.10.
This page looks at noise from ISO 100 to ISO 51200, and what the AI Denoise feature of Adobe Camera Raw at settings of 10 and 50 can do about it, versus without noise reduction.
Crops presented at native camera resolution.
ISO invariance
The Nikon Zf is a dual-gain sensor, meaning that its hardware behavior is different depending on ISO. It is not ISO invariant across the entire ISO range, but ISO invariant within two ranges. It appears that the cutoff is at or around the ISO 640 range. If you need an effective ISO of 800 or higher, set the camera to ISO 800 or higher rather than leave it set to a lower ISO—the camera hardware will give you cleaner results.
