Instantly process the high pixel count data of approximately 51.4 million effective pixels
Image processor PRIME III
The PENTAX latest image processor, PRIME III is used. This processor boasts an approx. maximum processing speed that is five times greater than the PRIME II, and instantaneous processing of the large data amounts produced by an approx. 51.4 million effective pixels. This processor also contributes to significantly improved performance, such as a faster Instant Review.
Design concept that brings out the full potential of the lens resolutionAA-filter-free
Although false colors and moire are suppressed, the low pass filter unfortunately reduces sharpness of the overall image. This filter was removed from the image sensor unit as part of the design concept to give first priority to resolution on the PENTAX 645Z. This construction succeeds in bringing out the full potential of the lens and image sensor's resolution. The unsurpassed resolution representation will resolve individual leaves on trees in a landscape shot.
Newly equipped with diffraction and color fringe correctionLens compensation function
The PENTAX 645Z is equipped with full-featured lens correction functionality. Together with distortion and magnification chromatic aberration, peripheral illumination correction and diffraction correction are newly added. Diffraction that occur when stopping down the lens during shooting are effectively corrected on the PENTAX 645Z. Additionally, it is equipped with fringe correction for use in processing RAW images. This camera will support the higher quality finish.
