In my review of the Pentax 645Z in Medium Format:

Aperture Series: Pine Creek Thunderstorms (645Z)

A discussion of the field curvature is included and should be read by any Pentax 90/2.8 user as essential working knowledge.

This aperture series includes HD and UltraHD images in both color and black and white from f/2.8 to f/16 along with extensive crops and commentary. The crops are also in UltraHD, as I deemed the larger size useful for context.
