Get Pentax 645 at B&H Photo.

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.

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.
