43.8 x 32.8mm
Unsurpassed resolving power and natural atmosphere provided by the large CMOS image sensor.
Resolution and depth of expression brought by the size of the imaging area. This is the reason that medium-format cameras have been chosen for high-end photography that gives the top priority to image quality. The PENTAX 645Z is equipped with a large, 43.8 x 32.8 mm CMOS image sensor. With an imaging area approximately 1.7-times larger than a 35mm full-frame format, a higher degree of the sharpness and ambiance of the scene can be captured. Also, because the depth of field is shallow, the blurring effects can be controlled freely. The PENTAX 645Z is all the more effective and expressive to focus on a single point that you want to express for exciting photos.
Exceed the standards of high quality imaging
51.4 million effective pixels
The PENTAX 645Z has approximately 51.4 million effective pixels. This number of pixels is an absolute advantage when photographing subjects that require high resolution, such as scenery. The difference in sharpness and density of detail comes across clearly even in A3 size prints. Also, as a rich amount of information is included in each shot, tone jumping is less likely to occur, when working with RAW images, letting you boldly change parameters and freely customize the finish without worrying about ruining the image.
Expanding the realm of exposure settings
Max. ISO 204,800
The PENTAX latest image processor, PRIME III is used in the 645Z. This processor boasts a maximum processing speed that is approx. five times greater than 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.
Instantly process approximately 51.4 million effective pixels
Image processor PRIME III
The ultra high-sensitivity max. ISO 204800 is made possible by delicate and thorough image 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 colours and moire are suppressed, low pass filters unfortunately reduce the overall sharpness of image. As part of the design concept this filter was removed from the image sensor unit 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 colour fringe correction
Lens compensation function
The PENTAX 645Z is equipped with fully featured lens correction functionality. Together with distortion and magnification chromatic aberration, peripheral illumination correction and diffraction correction are newly added. Diffraction that occurs when stopping down the lens during shooting is corrected effectively in 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 resolving 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 with a high pixel count. Highlight blow-out 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 colours 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 mobility-what was missing from medium-format digital cameras.
Quick and responsive operation has 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 improved, comparing to the PENTAX 645D. Also equipped with a large-capacity buffer memory the writing time to the memory card has become less, which helps you take a number of RAW-format images smoothly with continuous shooting. These features make it possible to continue releasing the shutter with a comfort that had not been previously possible on medium-format cameras. The PENTAX 645Z is ideal for portrait and moving subject photography.
An advanced Auto Focus system for high precision
The AF system used on the PENTAX 645Z is SAFOX 11. Diffraction lenses are used in the optical system for aberration suppression. By sharpening images on the sensor, superb focusing precision is achieved. A light source detection sensor is also included for thorough cancellation of even minute influence on AF from specific artificial light sources. This precision focusing and response system perfectly matches the needs of high-resolution images.
Superb focusing precision
F2.8 beam compatible AF
The three AF points at the centre of the screen support F2.8 beam AF. When using a lens with a maximum aperture value of F2.8, a high level of focusing precision is possible. This is especially effective for when you want to make the depth of field extremely shallow or to make severe focus in shots
Capture dark subjects that are difficult to see
-3EV compatible AF
By using a high-sensitivity AF sensor, a low luminance limit of -3EV is achieved (25 centre points). Even with darker subjects that are difficult to see, this AF provides smooth and accurate focusing for a greater range of scenes.
Superb subject sensing capability
27 AF points
27 AF points are available. 25 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.
The camera analyzes the subject and optimizes function linkage and control
Pentax Real Time Analysis System
This feature detects the colour distribution in the screen, subject colour, and its movement, and optimizes automatic linkage and control of AE, AF and white balance. 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 consistant shooting is possible.
Faithfully captures colour, shape, and movement for precise analysis
Approx. 86,000 pixel RGB metering sensor
The PENTAX 645Z uses an approximate 86,000 pixel RGB metering sensor which captures scenes on a real-time basis, detecting brightness, colour, and movement on a scale so fine 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.
Favorable colour reproduction in all areas of the image
Multi-pattern Auto WB
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 colour temperature differences due to differing light sources, shadow, and sunlight, and provides stable colour reproduction that looks similar to the way scenes appear to the naked eyes.
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 a downward direction and 125° upward direction. Incorporating a large 3.2 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.
Making Contrast AF possible
This model is equipped with the Live View function which can be used for accurate focus checking on a magnified display (max. 16x). In addition to Contrast AF which obtains extremely accurate focusing, you can set Focus Peaking and Face Detect AF. As effects such as Custom Image and white balance are reflected on the screen, you can expand your range of expression.
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.
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 that rivals that on 35mm full-frame cameras. The field of view is approx. 98%, and the focusing screen is replaceable. A natural bright matte screen is standard, making it easy to capture focus peaks.
Clears operation tests of 100,000 shots
High durability mechanism
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.
Airtight body that keeps out rain and dust
Dustproof, weather-resistant construction
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. The same construction is also used on AW lenses. When combined with an AW lens, this camera can shoot even in severe conditions such as. rain fall and dust.
Able to shoot even in cold climates
Cold-resistant operation guaranteed to -10°C
This camera was tested in -10°C environments, confirming operation accuracy, stability, responsiveness, and changes in battery status. With this kind of protection, you can always be ready to take the camera into cold environments where the digital devices normally do not work properly.
Seeking lightness and strongness
Magnesium alloy exterior
The camera exterior and tiltable LCD monitor are made of lightweight and high-strength magnesium alloy. This material provides superb shock absorption, and heat dissipation, as well as excellent electromagnetic shielding, high durability and reliability. It stands up to hard use and protects the internal precision mechanisms of the camera.
A high precision and durable body
Aluminum die-cast chassis
To achieve a chassis that supports the flange, viewfinder and optical system of the AF light path, a high level of strength and accurate dimensions are necessary. Die-cast aluminum was used for its high strength, achieving a highly precise assembly and high rigidity. Additionally, the image sensor unit is attached to the chassis via a heat dissipation shield. Heat is released by making the rear section of the chassis a heat sink, reducing noise that occurs due to dark current.
Remove dust using ultrasonic vibrations
DR II and Dust Alert
The PENTAX 645Z is equipped with DR II (Dust Removal II), to avoid the problem of dust particles. The DRII can effectively remove all dust particles clinging to the surface of the CMOS image sensor unit by vibrating the UV/IR reduction filter with piezoelectric element at supersonic speed.
Create impressive creations with three dimensionality and high sensitivity
Movie shooting functions
On the PENTAX 645Z, you can record Full HD movies at a maximum of 60i, and HD movies at a maximum of 60p. Even at the same resolution, when the large image sensor of the PENTAX 645Z is taken advantage of, depiction that overflows with three-dimensional detail can be obtained that rivals cinema camera super 35mm and 35mm full-frame cameras. As you can apply Custom Image such as Cross Process effects, you can create movies with a diverse array of tones. Setting the maximum sensitivity of ISO 3200 for recording is possible. One of the benefits is you can shoot movies with a minimum of lighting. In addition to a built-in stereo microphone, the PENTAX 645Z is also equipped with an external microphone jack (levels can be adjusted).

Automatically generates images with a wide dynamic range
HDR (High Dynamic Range)
A single image with a wide dynamic range is created from three images with differing exposures. In addition to adjusting the exposure amplitude*1 according to the scene, because the camera can automatically correct minor changes to the position of the composition between images*2, you can enjoy easy hand-held HDR photography. Also, because the original three images are saved as RAW data, you can use them separately for development as other creations. All three images are saved as a single RAW file, making data management easy.
*1 : Exposure amplitude can only be set when shooting
*2 : Automatic position adjustment may not be possible for large position differences and due to patterns in some subjects.
Select the composite mode according to your expressive intentions
Set the amount of shots (from 2 to 2,000) and merge them into a single image. Each time the shutter button is pressed, exposure is adjusted and images are merged, and you can check the results in detail on the LCD screen. You can select the composite mode from three options to match your varied expressive intentions.
[Composite Mode] ● Average
Creates a composite image with the average exposure. You can easily enjoy multi-exposure photography without adjusting the exposure for each shot
