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:
