Pentax 645Z
This extensive real-world evaluation of noise includes:
- HD and UltraHD entire-frame images ISO 100 to ISO 204800 in RGB.
- HD and UltraHD entire-frame images ISO 100 to ISO 204800 in RGB, gray gamma 2.2, and red/green/blue color channels.
- Four large actual pixels crops ISO 100 to ISO 204800 in RGB, gray gamma 2.2, and red/green/blue color channels.
In my review of the Pentax 645:
Pentax 645Z Pushing Up to ~6 stops (Fruit Arrangement)
Intermediate exposure values for pushes of 1/3/4/5/6 stops are shown along with two large crops that include RGB, gray gamma 2.2, red/green/blue color channels.
