Quote: Pentax K-1 Review
Advantages of Full Frame
As the first full-frame DSLR from Pentax, the K-1 opens up new opportunities for current users of the Pentax K-mount system or other crop systems.
The primary advantage of the full-frame format is superior image quality. Compared to an APS-C body such as the Pentax K-3 or K-5, the K-1 boasts more than twice the sensor area, at roughly 864 square millimeters, compared to 384.
Without getting overly technical, the larger sensor size enables higher resolutions, improved dynamic range, more accurate colors, and better performance in low light or at high sensitivity settings. This can primarily be attributed to larger pixel pitch, as bigger photo sites are able to pick up more light.
Secondary advantages of the full frame format include a more sizable optical viewfinder, shallower depth of field, less diffraction, and easier access to lenses with wider angles of view . . .
