Unsurpassed power of resolution and natural atmosphere provided by the large CMOS image sensor.

Resolution and depth of expression brought by the size of the imaging surface. This is the reason that medium-format cameras have been chosen for high-end photography that gives the top priority on image quality. The PENTAX 645Z is equipped with a large, 43.8 x 32.8 mm CMOS image sensor. With the size of approximately 1.7-times larger than a 35mm full-frame format, a higher degree of the sharpness and atmosphere of the scene can be captured.

51.4 million effective pixels

The effective pixels of PENTAX 645Z are approximately 51.4 million. This number of pixels is an absolute advantage when photographing subjects, such as scenery, that require high resolution. The difference in sharpness and density of details come across clearly even in A3 size prints. Also, because a rich amount of information is included in each shot, when working with RAW images, tone jumping is less likely to occur, letting you boldly change parameters and freely customize the finish without worrying about ruining the image.

Image Processor PRIME III

The PENTAX latest image proccessor, PRIME III is used in the 645Z. this processor boasts a maximum processing speed that is approx, five times greater then the PRIME II. So instantaneous processing of the large amounts of data produced by an approx. 51.4 million effective pixels is possible. This processor also contributes to significantly improved performance,such as a faster Instant Review.

Max. ISO 204800
Expanding the realm of exposure settings

The ultra high-sensitivity max. ISO 204800 is made possible by delicate and thorough noise processing through an image processor and image sensor of a high SN ratio. Even at high ISO settings, excellent image quality is possible with reduced noise and outline blurring. Even in the same shooting conditions, the greater freedom      for the wider setting of aperture value and shutter speed allows you to express blur and emotion just the way you like.

Design concept that brings out the full potential of the lens resolution

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.

Lens compensation function
Newly equipped with diffraction and color fringe correction

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.

Superior image depiction provided by a large and high pixel CMOS image sensor

Fine and smooth gradations
The large CMOS image sensor has ample pixel pitch and output a high SN ratio signal even in a high pixel count. Highlight blowout and loss of shadow detail are uncommon on the PENTAX 645Z, and tonal changes are reproduced in the high pixel count areas only. The smooth connection between shadows and colors provides images with more detailed descriptions.

Beautiful blurring and rich three-dimensional feel
The main feature of medium-format cameras can also been seen in their blurring effects. The depth of field is shallow and blurring is smooth. Subjects captured with the aperture at its widest setting appear more three-dimensional than even when seen with the naked eyes. These features make the soft, rich three-dimensional expression and atmosphere that are particular to medium-format cameras possible for a deeper significance in photographs.

The responsiveness what was missing from medium-format digital cameras.

Quick response and operation have been achieved by renewing the entire image processing performance. In addition to Auto Focus, image processing, the operation of Instant Review display has been significantly fastened, comparing to the PENTAX 645D. Also, the large-capacity buffer memory is equipped, and the writing time to the memory card has become less, which help you smoothly take a number of RAW-format images with continuous shooting. These features make it possible to continue releasing the shutter with a comfort that had not been possible on medium-format cameras. The PENTAX 645Z is ideal for portrait and moving subject photography.

The backbone of this is the scene analysis system that links the approx. 86,000 pixel RGB metering sensor and PRIME III. By comprehensively analyzing scenes, high-precision and stable shooting is possible.

-3EV compatible AF
Capture dark subjects that are difficult to see

By using a high-sensitivity AF sensor, a low luminance limit of -3EV is achieved (25 center points). Even with darker subjects that are difficult to see, this AF provides smooth and accurate focusing for a greater range of scenes.

27 AF points
Superb subject sensing capability

27 AF points are placed. 25 of those points are cross-type focus points equipped with line sensors in both the horizontal and vertical directions. The excellent sensing capability of this function applies to all subjects.

F2.8 beam compatible AF
Superb focusing precision

The three AF points at the center of the screen support F2.8 beam AF. When using a lens with a maximum aperture value of F2.8, a high focusing precision is possible. This is especially effective for when you want to make a depth of field extremely shallow or to make severe focus in shots.

Approx. 86,000 pixel RGB metering sensor
Faithfully captures color, shape, and movement for precise analysis

The PENTAX 645Z uses approximate 86,000 pixel RGB metering sensor which captures scenes on a real-time basis, detecting brightness, color, and movement on a scale so finely that it is on a different dimension than the traditional 77 zone metering system. The low-luminance limit is -1EV (ISO 100/55mm, F2.8). This feature achieves a high accuracy of exposure control even with a low illumination.

Multi-pattern Auto WB
Favorable color reproduction in all areas of the image

The PENTAX 645Z is equipped with Multi-Pattern Auto WB, which divides the screen into small sections and applies the optimal white balance to each. This function resolves the color temperature differences due to differing light sources, shadow, and sunlight, and provides stable color reproduction that looks similar to the way scenes appear to the naked eyes.

Dual slot
High-speed file writing

The dual slots conform to the UHS-I standard. With high-speed writing, buffer clearing time is shortened, contributing to quick shooting. Additionally, files are written sequentially to two separate card slots for recording duplicates, and RAW/JPEG separation. Eye-Fi cards and FLU cards (O-FC1, optional) can also be used. Note: Eye-Fi and FLU cards with wireless LAN functions can be used in SD2 slot.

Equipped with a tiltable LCD monitor that can be moved -35° to 125°.

The PENTAX 645Z is equipped with an LCD monitor that features a tilt mechanism. It can be moved 35° in downward direction and 125° upward direction. Incorporating a large 32-inch, approximately 1.037 million dot, high-definition, wide viewing angle panel, this feature makes it possible to shoot at low angles and high angles while looking at the Live View display from a more comfortable position. It also features an air gapless construction that suppresses internal reflections. Reinforced glass with AR coating is used for superb visibility, protection from scratches, durability, and is crush resistant.

Because effects such as Custom Image and white balance are reflected on the screen, you can expand your range of expression.

Integrated design
Achieving mobile, hand-held shooting

The PENTAX 645Z inherits the traditional DSLR style from the PENTAX 645 series in its integrated viewfinder, image sensor unit, and grip. Excellent operational reliability and focus accuracy are achieved so you never have to worry about poor connection with the digital back, or focus errors due to poor mounting. Additionally, by optimizing the weight balance and making the grip shape easy to hold, a medium-format digital camera that offers comfortable hand-held shooting is achieved.

Optical viewfinder
Wide open field of view that is only available on a medium-format camera

To make the camera body more compact, a trapezoidal prism was used. The mount is tilted forward at 9° from the body, further optimizing the optical route for a shorter overall height. A Kepplerian telescope type is used for the eyepiece optical system, achieving both a high magnification factor and wide angle of view. This viewfinder features a large field of view rivals that on 35mm full-size cameras. The field of view is approx. 98%, and the screen is replaceable. A natural bright matte is standard, making it easy to capture focus peaks.

High durability mechanism
Clears operation tests of 100,000 shots

The PENTAX 645Z is equipped with a high-speed, long-life drive unit that clears durability tests of over 100,000 shots, equivalent to double that of the PENTAX 645D. This not only allows you to shoot a continuous shot but also to shoot people and moving objects that are frequently being shot and to make digital archives, all of which meet the difficult needs of pro photographers.

Dustproof, weather-resistant construction
Airtight body that keeps out rain and dust

Anticipating poor conditions encountered in outdoor shooting, this camera features a dust and splash resistant construction. 76 different places including buttons, dials, and covers are carefully sealed to keep out raindrops, humidity, and dust.
