Pentax 645Z Overview

Take your photography to the next level with this Pentax 645Z Medium Format DSLR Camera with 55mm Lens Kit from B&H. Packing in a large 51.4MP 43.8 x 32.8mm CMOS sensor, the 645Z is an exceptional image-making machine. Additionally, when paired with the D FA 55mm f/2.8 AL[IF] SDM AW Lens users will be able to embrace a normal 43.5mm equivalent field of view.

Pentax 645Z Medium Format DSLR Camera

The Pentax 645Z features a 43.8 x 32.8 mm CMOS sensor with 51.4 effective megapixels. The sensor is designed without an anti-aliasing filter to maximize sharpness and details. RAW files can be recorded at 14-bit and saved using either the proprietary PEF format or Adobe's DNG format. 

An ISO range from 100-204,800 and high S/N ratio provides low noise, low light capability, and the Prime III image processor lends itself to fast image capture with a maximum of 3 fps continuous shooting. The SAFOX II autofocus module utilizes 27 autofocus points including 25 cross-type sensors and 3 AF sensors dedicated for low light focusing. The new Real Time Scene Analysis System features an 86,000 pixel RGB light-metering sensor for enhanced accuracy of exposure, white balance, and auto-focusing.

Full HD 1080 60i/30p/24p video capture is supported in the H.264 format with a dedicated button for instant switchover from stills to video. An external microphone jack enables high quality audio recording with manual sound level control and monitoring. An HDMI port outputs HD images to HDTVs and a USB 3.0 jack enables fast image transfer to your computer. Interval recording for time-lapse videos is supported with an output of UHD 4K resolution.

A 3.2", 1037k-dot, tilting, air-gapless, LCD monitor enables live view composition and playback viewing from a various angles and a trapezoid-shaped glass prism viewfinder with Kepler telescope-type eyepiece unit provides traditional eye-level composition. The design of the viewfinder also helps to achieve the relatively compact size of this medium format camera. The 645Z is extremely durable with an aluminum alloy chassis, magnesium alloy shell, and 76 specific weather seals to keep out moisture and dust. It is a camera designed for field as well as studio and can operate in temperatures from 14-104°F. 

The camera body also features a deep set ergonomic grip, ideal for hand-held shooting, easy-to-access buttons, and a top-plate, sub-LCD screen that is angled up for easier visibility of camera information. A hot shoe mount is supported, and in addition to the tripod socket on the camera's base, a second tripod socket is located on the side of the camera for convenient and stable tripod shooting in the vertical position. Two SD slots are provided for versatile image storage and both Flucards and Eye-Fi cards are compatible for wireless image transfer. A free plug-in is available for seamless tethered shooting support in conjunction with Adobe Photoshop Lightroom, along with the USB 3.0 output for fast performance.

The 645Z is compatible with the new FA autofocus lenses as well as older 645 lenses and with Pentax 67 medium format lenses when used with an adapter.

51.4 MP CMOS Sensor

The 645Z offers a 43.8 x 32.8 mm 51.4MP CMOS sensor, which is ideal for ultra-high resolution imaging, large printing applications, and cropping flexibility. Compared to a CCD sensor, a CMOS sensor provides higher ISO sensitivity, expanded uses for live view, faster continuous shooting, and improved movie recording capabilities.

Anti-Aliasing Filter-Less Design

The optical, low-pass, anti-aliasing filter found in most CMOS sensors has been removed from the 645Z design to maximize image sharpness and fine details.

RAW Capture

RAW files can be recorded at 14-bit and saved using either the proprietary PEF format or Adobe's DNG format for greater post-production control and flexibility.

Prime III Image Processor

The 645Z offers a fast frame rate of 3.0 fps, quick image processing to rapidly review images, and swift image transfer with USB 3.0 computer connection.

ISO 100 to 204800

A sensitivity range from ISO 100 to 204800 along with enhanced noise reduction capabilities enables effective low-light capture.

Full HD 1080 Video Capture

The 645Z supports full HD movie capture in the H.264 format at 60i, 30p and 24p, including the ability to switch from still image to video recording with the flip of a dedicated switch. Equipped with a built-in stereo microphone and a terminal for external microphone connection, the user can also adjust the audio recording level manually and visually monitor sound levels during recording.

Interval Shooting with 4K Output

In-camera time lapse sequences can also be recorded using the built-in intervalometer, allowing up to 2000 shots to be recorded with 2 second to 24 hour delays, and output as 4K (3840 x 2160) files.

3.2" 1,037k-dot Tilting Air-Gapless LCD

A 3.2", 1,037k-dot, air-gapless, LCD monitor is available and features a tilting design (-35° down and +125° upward) to benefit use from high or low viewing positions. An electronic level gauge can be utilized with either the viewfinder or LCD monitor during shooting, and when working in live view, a variety of grid overlays and manual focus peaking can be used for greater focusing accuracy.

Pentaprism Viewfinder

A large, trapezoidal-shaped, glass pentaprism with Kepler telescope-type eyepiece enables bright and clear eye-level finding with 98% frame coverage.

SAFOX II Autofocus Module

The SAFOX II autofocus module maximizes 27 AF sensors and a vast light sensitivity range of -3EV to +18EV. The new focus module includes 25 cross sensors and three AF sensors dedicated to low light focusing.

Real Time Scene Analysis with 86,000 Pixel Sensor

The new Real Time Scene Analysis System features an 86,000 pixel RGB light-metering sensor and improved algorithms that further enhance accuracy of exposure, white balance, and auto-focusing.

Multi-Pattern Auto WB system

A Multi-Pattern Auto WB system can be used to intelligently adjust white balance settings when mixed lighting is prevalent. For example, if both flash and ambient lighting are utilized, different white balance settings are used within the different regions of an image to more accurately portray overall color balance.

Durable, Weather-Sealed Form Factor

Offering a compact build for a medium format camera, the 645Z provides an ergonomic grip, large buttons, and 76 specific weather-seals to protect the camera from moisture, sand, and dust. It is capable of shooting in temperatures ranging from 14-104°F, and its aluminum alloy chassis and magnesium alloy body are durable for years of service in studio or on location.

Dual Memory Card Slot and FLU Card Compatibility

Dual slot SD/SDHC/SDXC memory card support ensures fast and reliable storage for high resolution image files, simultaneously saving in multiple formats, assigning images to different cards based on their original format, or easily holding one memory card in reserve. In addition to standard SD cards, the 645Z is compatible with Eye-Fi and Flucards for wireless image transfer and with the Pentax Flucard remote camera control from a compatible smart devise.

Lens Compatibility

The 645Z is compatible with new D FA autofocus lenses as well as older 645 lenses as well as Pentax 67 lenses via an optional adapter.

Pentax-D FA 645 55mm f/2.8 AL[IF] SDM AW Lens

New camera, new lens: this Pentax-D FA 645 55mm f/2.8 AL[IF] SDM AW Lens is the first model of the Pentax-D FA 645 lens series created for the Pentax 645D digital medium-format camera. With a focal length that's equivalent to a 43.5mm standard lens (in 35mm), it features optics optimized for digital photography to assure exceptional performance, and also provides an image circle covering the image area of existing 645-format film SLR cameras. It has dependable, dust-proof, weather-resistant construction for active outdoor photography.

This lens features a Supersonic Direct-drive Motor (SDM) autofocus drive and Quick-Shift for instant autofocus/manual focus switching,  Aero Bright coating to help prevent flare and ghost images, and it's Pentax's first 645 system lens to incorporate a rounded diaphragm for improved bokeh (the aesthetic quality of the blur in the out-of-focus areas of an image).

State-of-the-Art Optics

Incorporating high-performance, hybrid aspherical optical element in its optics, this new standard lens (focal length equivalent to 43.5mm in the 35mm format) offers exceptional image-resolving power with outstanding brightness levels even at the edges, while compensating various aberrations to a minimum. All lens characteristics are optimized for digital photography: for instance, flare and ghost images are minimized by applying exclusive lens coatings to optical elements and employing anti-reflection materials for the interior of the lens barrel.

Versatile Standard Lens

When mounted on the PENTAX 645D camera body, this standard lens offers a focal length which produces an angle of view close to that of the human eye. As the result, it can be used for many different kinds of subjects and applications, including landscapes and portraits.

Dustproof, Weather-Resistant Construction

Seven special seals make this lens dustproof and weather-resistant. This lens coupled with the Pentax 645D camera body provides a durable, reliable digital SLR camera that performs superbly, even in rain, mist, or locations prone to water splashes and spray. The "AW" (All Weather) designation in the lens name testifies to the weather-resistant construction and it is rated to operate in temperatures from 14-104ºF (-10 to 40ºC).

Aero Bright Coating Dramatically Improves Image Description in Backlight

The Pentax original Aero Bright coating on this lens delivers brilliant, high-quality images by preventing flare and ghost images more effectively. This exclusive coating effectively reduces lens reflectance and greatly increases light transmittance by forming a silica aerogel layer with uniform pores on the surface of optical element.

Rounded Diaphragm to Produce a Beautiful Bokeh

The first Pentax medium-format interchangeable lens to feature a completely rounded diaphragm, it creates a natural, beautiful "bokeh" (out-of-focus rendition), while minimizing the streaking effect of point light sources.

Smooth, Quiet SDM Autofocus

The SDM (Supersonic Direct-drive Motor) autofocus mechanism operates smoothly and quietly using the supersonic motor installed inside the lens barrel.

SP Coating Blocks Dust and Dirt

The front surface of the lens is treated with Pentax's SP (Special Protect) coating, which applies a fluorine compound to the lens surface through a vapor deposition process. This SP coating effectively repels dust, water and grease, and also makes it easy to wipe off fingerprints and cosmetics.

Advanced Focus Options

Quick-Shift Focus system instantly switches to manual focus operation, after the subject is captured in focus by the AF system.

Great camera! Does not fail on image quality, build quality, of ease of use, I just bought a second one! I'm writing this review to let photographers know that Capture One is now supporting RAW files from this camera. BTW: use a tripod.

Great Equipment but Needs A Left Grip

By Lehman
Rated 5 out of 5
Date: 2020-06-09

Most of my work is done with a tripod, but I do hand-hold some shots. I’m used to heavy cameras but this one needs a secondary grip to shoot for extended periods in hand. I found my grip from SmallRig. I do not shoot video so no hate mail. I chose this grip because of the smooth machining and well thought contouring. It feels very comfortable in my hand. The problem is that the attachment hardware is metric and the tripod mount holes in the 645z are imperial. I got it work by discarding the rosette wheel from the bracket and replaced it with an automobile grade bolt and lock washers.  The alternate mounting holes on the bracket are Imperial (go figure). The images show the results. It works great, it is stable, and feels good.

Portrait Shooters beware!

I am utterly disappointed to report that this camera does not allow only back button focus. If you are like me and shoot lots of portraits (handheld and tripod) then it is critical to be able to disable the shutter release focus. It is so frustrating that Pentax didnt allow for this, so I will be returning the camera. I did a whole portrait session trying to focus on the models eyes and recomposing only to have the camera re-find its own focus point when I hit the shutter. UGGGHHHH! Loved this camera otherwise.

The affordable camera that could, but didn’t.

Having switched (in 2014) from the slow, Mamiya Leaf Credo 60 with ordinary AF and poor high ISO capability i have found the 645z a very worthy replacement. (Relative to the Phase and not a 35mm camera) AF is significantly better, bust rate is faster, high iso ability is as good as a d850, build quality is outstanding and with the availability of legacy lenses it is extremely economical. I love this camera but after 4 years of tethered struggle, I’m going to change systems. If Pentax gave this camera a fighting chance and simply fixed the tethering issues I believe it would legitimately rule the MF roost. Please Pentax, sort it out. It’s just software!!!!

I have been a full time professional commercial/promotional photographer in Maryland for the last 16 years and have used primarily nikon and then canon. I wanted to step up my image quality and bring more of a film look to my commercial and individual work without moving into a 40 grand hasselblad system that I just couldnt justify. I did a ton of research and kept coming back to the pentax 645z. It fit my budget and the reviews looked solid so I pulled the trigger on the camera body, the 55mm, 120mm macro, the 150mm and the 90mm macro. I got this entire setup for less than 15 grand which is what I would have spent on my other choice which was the hasselblad h6d-50c body cost by itself. having never used pentax before i was a little nervous about dropping this kind of money without as much as testing the camera or lenses once. The camera is gorgeous overall, laid out very well as far as dials and buttons and looks big and sturdy like a medium format camera should. I didnt want to write a review until i did a few sessions on it so here it is. First and foremost, the camera is easy to learn. After messing with it for a few hours I had the bulk of the settings and features nailed down and the camera was setup for my needs. If shooting speed is a must for you, this IS NOT the camera for you. It doesnt have that ultra fast, tight shutter speed of the canon 5d mk iv and he focusing speed is definitely slower but I expected that. The shutter sounds more like a film based shutter which has a louder, slower clunk sound to it. I love the extensive white balance settings and I love being able to store 3 separate kelvin temps to presets in the WB menu. The max shutter speed when using my profoto/multiblitz strobes is 125 which isnt great but Im usually shooting around there anyway so that doesnt bother me either. I wouldnt use this camera for studio speed shooting like I do for Under Armour ads or sessions where the model is swinging a bat or performing at high speed. I would probably go back to using the mark iv for speed. I wanted this camera for straight up image quality and thats exactly what it delivers. Im a huge fan of jpeg shooting for day to day shoots and I have NEVER seen such amazing skin tones from a digital camera EVER. The jpegs out of this setup look absolutely stunning. I love the fact that the images are now 10 x 7.5 files instead of the dslr 10 x 6.667 files. It just looks more magazine like and the extra frame real estate is something I really love using medium format. There is definitely more life like quality to the images and the file sizes are HUGE! Your looking at 60mb jpegs and 130mb raw images easily. You can take a full body shot and literally crop it into a perfect looking headshot which I was blown away by. Im used to using dual batteries in a grip setup like most of you use with your canon/nikon rigs so going back to a single battery scared me a bit and I was afraid I would have to swap out batteries multiple times during my shoots which was NOT the case. In the four sessions I shot with this camera I didnt have to change the battery once during any of the sessions and I captured at least 500 images or more each session which was impressive. As far as lenses are concerned the 120mm and the 150mm have been gold! There are not as many excellent lens choices as there are for the canon and nikon dslr bodies which hopefully changes. The 150mm is my new favorite for this camera and an absolutely needed lens for fashion, headshots and portraits. The bought a used copy of the 90mm from b & h which ended up having a loose inner glass element so I had to return it but the shots I did get to use it for looked great. Im not sure if its worth the near 5 grand its priced at but my opinion is still out on this one. The 150mm and 120mm lenses are beyond worth it. The 55mm that I ordered as a package with the camera body works great and is absolutely worth the 1 grand price tag. The great thing about the pentax lenses is that most all of the them have the same 67mm filter ring size so caps, filters, etc. are interchangeable. If you are on the fence about this camera or have been doing research forever and still trying to decide if this camera is a needed step up from your dslr setup it all depends. If you are like me and want to step up your image quality and shoot on something new and different then its worth it in every way. I was tired of the same canon 5d mk images and wanted a new spice in my rack. This camera inspires me and makes me want to shoot. I shoot professionally everyday and honestly I get bored of the same look on the same camera with the same lenses so I NEEDED something different. Will you see a difference in the image quality of your shots....yes. It wont make bad shots look good but it will push your creative ceiling higher and give you a taste of the big boy camera look without having to drop 50 grand on a hasselblad system. This is my new favorite camera, hands down!

Superb gear at a extremely fair price

I have been shooting the 645 system ( 67) since their inception, decades ago.� In fact, the original 645 replaced a Hassleblad. Over the years some extremely well made glass was produced and bought. Everything from concerts, sports, fashion, portraits, landscapes etc were shot, with absolutely NO downtime, ever. Therefore when the 645z came out, it seemed logical to use the legacy lenses. The body itself is far less expensive than the nearest competitor, but price was not the only factor. Image quality is perfect for my needs. I have exhibited prints at 60" by 40" with no fall off at all in sharpness or quality. Recently, I completed my next series for a traveling show, and every image was shot without film, using one single legacy lens, on the 645z. The images are really great and will be the basis for a book, as well.� This body has turned out to be a great value. There has been no need for servicing, so no comment as to that.� The ergonomics are simple and it is very sturdy. The Pentax operating system is different than Nikon/ Canon/ Hasselblad. But every bit as thoughtfully done. In camera multi-exposures? No problem. Autobracketing? no problem? Mirror lock up? no issue. Live view for roughing in light and detail? no problem. Synch speeds are not an issue for my practice, but for some HSS is mandatory. When coupled with vintage glass, the results are great. With the new digital glass, micro-contrast and bite are as expected. There is absolutely no doubt in my mind that this is the very best bang for the buck. When factoring in the availability of great used glass, it becomes a no brainer. Last week I did and A/B test using 3 types of film ( 645nII body) and the 645z. All images were great. The exposures were dead on between the two meters. But the film might actually never get printed unless a client wants a billboard sized image. Gear conversations are boring: creating art or beauty is the whole point of the exercise. Once one gets used to this system, it is like a favorite pair of jeans that one can count on . Buy it.

Re Review by Adrianne, back button only focus is possible, see the settings in button customization. Back to the camera: I bought the 645z in Jan 2015 and have been using it as my primary camera ever since. After numerous photo trips to Africa, Iceland and Norway, where it worked fine in 40 degrees C as well as minus 34 degrees C in the arctic winter weather. Built robust and waterproof it just doesn't stop. In the arctic the camera stayed in sub zero temperatures all the time to avoid condensation. I only removed the SD card to copy files up my laptop inside the warm cabin, then returned it to the camera, in sub zero temperatures. Didn't have battery problems either. I'm considering a second 645z.

The review about the back button focus problems ...

The review about the back button focus problems concerns me. Is that true? The back button focus is overridden by touching the shuttter button? What if you are using a remote trigger? Does that fix the problem?
Asked by: Andy
Upon testing several models, if you press the back button for focus then press the shutter button to take the photo, the shutter button does not override the back button focus.

Asked by: Anonymous
For all Pentax 645AF2, 645AF and 645A lens you mount to this camera youll multiply the given focal length by 0.79 to calculate the 35mm-equivalent focal length. As such, a 50mm lens on the Pentax 645Z Medium Format DSLR Camera would be the equivalent of a 39.5mm lens on a 35mm film camera.

In order to mount Pentax 67 series leaf shutter lenses onto the 645Z, you will need an adapter such as the FotodioX Pro Lens Mount Adapter for Pentax 67 Lens to Pentax 645 Mount Camera B&H # FOPP645AP67. Please see the image below for reference.
