In my review of the Pentax 645Z:
This example shows off what the Pentax 645Z sensor can record with a high performing lens.
Includes HD and UltraHD images from ƒ/4 to ƒ/22 along with large crops.

My thanks for how quickly you jumped on the 645z! Sounds like your expectations were fulfilled, for better or worse. Now we need the Sigma 645 Art series...
I am always impressed with your energy and thoroughness. You earn your subscription fee many times over!
DIGLLOYD: lots of positives with the 645Z, but lenses are the weak point of the system.
