Pentax 645z: Noise from ISO 100 to ISO 204800 with RGB, Channels, Grayscale

Get Pentax 645z and Pentax 645 lens at B&H Photo.

This elaborate 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 grayscale using gray gamma 2.2.
  • One high-key and one low-key actual-pixels large crop ISO 100 to ISO 204800 showing RGB, gray gamma 2.2, and invididual R/G/B color channels.

The Pentax 645Z handles noise supremely well, and this series should be exceptionally useful to 645Z shooters in seeing just where the limits are for their own shooting style. It is also useful for black and white shooters in seeing how black and white rendition might fare at very high ISO values. The 645Z sensor is a breakthrough for medium format in noise terms.
