APS-C

The PENTAX K-3 Mark III is a premium APS-C DSLR camera. It's the most capable APS-C camera that the brand has released and the first to offer 4k video capability and a touchscreen. Its rugged all-weather design feels exceptionally sturdy, and the camera includes plenty of customization options. Despite the marketing gimmick of a 1,600,000 native ISO, its sensor does genuinely deliver when it comes to high-ISO performance and dynamic range. But even with these upgrades, the camera still feels like a bit of a relic in the era of mirrorless cameras, and with a price that far exceeds any comparable APS-C models, it's hard to justify unless you're dedicated to PENTAX's old-school approach to cameras.

Our Verdict

7.4 Travel Photography

The PENTAX K3 III isn't especially good for travel because of its bulky size and weight. However, it's still an excellent photography camera if you don't mind traveling with a bulkier kit. It has an excellent battery life, which can last over multiple days depending on your usage habits, and it's one of the best in its class for high-ISO performance, which is great for getting clean shots in low light or at night. That said, its autofocus system lags behind many mirrorless competitors when it comes to tracking fast-moving subjects.

Pros
  • Excellent image quality.
  • Feels well-built and very comfortable to use.
  • Excellent battery life for photos.
Cons
  • Poor autofocus tracking performance.
  • Heavy and bulky.
7.9 Landscape Photography

The PENTAX K3 Mark III is great for landscape photography, especially for an APS-C camera. Its sensor punches above its weight, with excellent dynamic range to capture a wider array of detail in high-contrast scenes and amazing high-ISO performance for low-light or nighttime landscapes. The camera's also incredibly sturdy, with a weather-sealed design that allows you to shoot in all kinds of weather conditions without worry. It just isn't the most portable camera, so it's less convenient to take on long hikes or remote shooting locations.

Pros
  • Excellent image quality.
  • Weather-sealed.
  • Feels well-built and very comfortable to use.
Cons
  • Heavy and bulky.
7.7 Sport & Wildlife Photography

The PENTAX K3 III is okay for sport and wildlife photography. It can shoot at a quick max burst rate for sequential action shots, and the camera is incredibly well-built, meaning it can put up with heavy use in adverse shooting conditions. That said, it has a very limited buffer depth, and it takes a long time to empty its image buffer once full, meaning that if you prefer to shoot continuous bursts for action shots, you'll frequently experience long interruptions. The camera's autofocus system also struggles to keep track of moving subjects, especially if they're moving at a fast pace.

Pros
  • Excellent image quality.
  • Fast continuous shooting speed.
  • Feels well-built and very comfortable to use.
Cons
  • Poor autofocus tracking performance.
  • Heavy and bulky.
  • Limited buffer capacity with long clearing time.
2.5 Vlogging

The PENTAX K3 III isn't designed for vlogging. It has a fixed screen that doesn't let you monitor yourself while filming, and its heavy weight and large size make it impractical for walk-and-talk style vlogs.

Pros
  • Feels well-built and very comfortable to use.
Cons
  • Heavy and bulky.
  • 4k frame rates and recording capability are limited.
  • Fixed screen.
6.1 Studio Video

The PENTAX K3 III isn't well-suited to studio video. While it's the first Pentax camera with 4k video capability, it's still primarily a photography camera, and it shows. It can only record 4k videos in short clips and with a significant crop. Video quality isn't especially impressive either, and its contrast-detect autofocus system doesn't fare well with faster subjects.

Pros
  • Feels well-built and very comfortable to use.
  • Wide array of inputs and outputs.
Cons
  • Heavy and bulky.
  • 4k frame rates and recording capability are limited.
  • Disappointing autofocus tracking in video.
3.5 Action Video

The PENTAX K3 III isn't designed for action video. It's a hefty camera meant for handheld shooting rather than mounting, and beyond that, its autofocus struggles to effectively track moving subjects, so it's not the best choice for filming sports or action.

Pros
  • Weather-sealed.
  • Feels well-built and very comfortable to use.
Cons
  • Heavy and bulky.
  • 4k frame rates and recording capability are limited.
  • Not waterproof.
  • Disappointing autofocus tracking in video.

Differences Between Sizes And Variants

The PENTAX K-3 Mark III comes in two color variants: 'Black' and 'Silver'. We tested the 'Black' model, and you can see our unit's label here

You can buy the camera body on its own or bundle it with one of several available lens kit bundles, depending on the retailer. 

Let us know if you come across another variant or if your PENTAX K-3 III doesn't correspond to our review, and we'll update it.

Compared To Other Cameras

The third iteration of the PENTAX K-3 is a fantastic DSLR camera. It's ruggedly built, with plenty of thoughtful design features and customization options to give you more control over your shooting experience, and a powerful sensor that's sure to take beautiful photos in the right hands. However, it's also one of the most expensive APS-C cameras on the market, and in the age of mirrorless supremacy, it leaves a lot to be desired when it comes to shooting speed, autofocus, and video capability, making it doubtful if it's worth the price.

If you're looking for other DSLR options, check out our recommendations for the best DSLR cameras. Otherwise, you can explore mirrorless alternatives by checking out our list of best mirrorless cameras or see the best cameras we've tested for photography.

Fujifilm X-T4

The PENTAX K-3 Mark III and the Fujifilm X-T4 are both premium APS-C cameras, but they use different technologies with different advantages and disadvantages. The PENTAX is a DSLR, so it's heavier and bulkier, but it has an optical viewfinder and longer battery life. The Fujifilm, on the other hand, is a mirrorless camera, allowing for a much more portable body. It also performs significantly better when it comes to video features and autofocus tracking. 

Canon EOS 5D Mark IV

The Canon EOS 5D Mark IV and the PENTAX K-3 Mark III are both DSLR workhorses with sturdy builds and great ergonomics. Having said that, each has its own advantage over the other. The Canon uses a higher-resolution full-frame sensor, giving you more leeway to crop in images and when shooting in low light. The PENTAX, despite its smaller APS-C sensor, is a newer camera with newer tech, giving it a leg up when it comes to max burst rate and max ISO, though the Canon still has a larger photo buffer and more reliable autofocus system.

The PENTAX K-3 Mark III uses the Pentax K-mount, which is compatible with K, KA, KAF, KAF2 (with power zoom), KAF3, or KAF4 lenses. The camera's weather-sealed and advertised to be dustproof as well as cold-resistant down to -10°C (14°F).

The camera has three command dials. By default in manual mode, the front dial near the shutter button controls shutter speed, the rear dial controls aperture, and the top dial (or 'E Dial') controls ISO. You can customize these and more (up to 10 buttons in total are customizable) to suit your preferences, and you can set different customizations for each shooting mode, which is great.

The PENTAX K3 Mark III has a great battery life. Its 800-shot CIPA rating is better than most mirrorless models and is quite good for a DSLR, though it falls far short of some Nikon models like the Nikon D780. What that means is you're likely to get plenty out of this camera on a full charge, though that depends on how you use it.

It isn't quite as good for video, though it'll still last for about an hour and a half of continuous video recording. Just be aware that the battery can overheat when recording in 4k for longer periods.

The PENTAX K3 Mark III includes eight different shooting modes to give you more control over exposure parameters and 12 custom image modes to adapt to different scenes or desired effects. Each image mode is customizable, allowing you to manually adjust settings like hue, contrast, saturation, color temperature, and more to change up the look of JPEG files. Also, the electronic shutter function is only available after upgrading to firmware version 1.10.

The PENTAX K-3 III can shoot at a quick max burst rate of 11 fps, which is especially impressive relative to other DSLR cameras. It's more than fast enough for most shooting situations where you'd want to capture fast action like sports. That said, it has a very small photo buffer, even when shooting in JPEG, and on top of that, it takes a very long time for it to clear its buffer once full. That means even though you can shoot in quick bursts, you're going to quickly be interrupted, which isn't ideal when you're trying to capture fleeting moments.

The PENTAX K-3 Mark III has a decent autofocus system, although it's most effective when shooting through the viewfinder, which is what we used to achieve the results above. When shooting through the LCD monitor in Live View, the autofocus is very unreliable at tracking moving subjects. No surprise considering it uses a contrast-detection AF system here, unlike a DSLR like the Nikon D780, which implements faster phase-detection AF in Live View.

It does a decent job of tracking faces. It's a bit slow and can sometimes lose its target when the person is moving briskly towards the camera. Its general subject tracking does pretty well, though. All in all, it's an effective AF system that'll perform well for a variety of situations and subjects but doesn't quite compete with the leading AF systems found on the latest mirrorless cameras.

The PENTAX K-3 Mark III features in-body image stabilization, and it does a fantastic job of stabilizing the sensor, so you can get clear handheld shots at very slow shutter speeds. We used the Pentax HD-DA 16-50mm f/2.8ED PLM AW lens, which doesn't have optical stabilization, but you can expect similar performance even with a kit lens and possibly even better performance with an optically stabilized lens.

The PENTAX K-3 Mark III has excellent dynamic range. It's right up there as far as APS-C cameras go and even surpasses a lot of older full-frame DSLRs. All in all, it can capture a wide range of highlight and shadow detail in high-contrast scenes. It also has really good exposure latitude, so you can make pretty significant exposure adjustments to your photos without introducing a whole lot of noise.

Noise handling is excellent when shooting in JPEG. The camera processes photos well at high ISOs, so noise is barely visible, though of course in dim lighting conditions, it's harder to avoid introducing noise, and photos become unusable at the extreme end of the camera's ISO settings. That's especially the case at the camera's max ISO of 1,600,000, as you can see here. That said, there are very few, if any, real-world scenarios in which you'd use ISO 1,600,000, which is more of a marketing gimmick, so it's not an issue.

  • RAW SNR 18% At ISO 25600: 24.89 dB
  • RAW SNR 18% At ISO 51200: 22.61 dB

The differences are marginal, so you can just use whichever format you prefer.

The camera has fantastic RAW noise handling, far better than most APS-C cameras we've tested. With shorter exposure times at high ISOs, noise is more visible, but RAW files are still relatively clean.

It can't record 4k / 60 fps like the latest video-centric cameras can, but it records at up to 30 fps, which is great for standard and more cinematic video work. You just can't get smooth action footage or create slow-motion 4k video with these frame rates.

Internal recording isn't great in 4k, but that's not unusual, considering this camera's mainly aimed at photographers. It's capped to a seven-and-a-half-minute recording time, which doesn't give you a lot of time to record. Bit rates are also small, and it can only capture 8-bit 4:2:0 video internally, so it isn't capturing a great amount of information, resulting in lower overall video quality.

The PENTAX K-3 Mark III has a poor autofocus system when shooting 4k video. It's slow and unreliable, even when using a high-end lens like the DA 16-50mm f/2.8, which uses a PLM motor for autofocusing. While the motor is quiet, which is good for video work, it's still very slow to focus. The camera has face detection and does a good job of recognizing human subjects in the frame, but ultimately, it struggles to keep up with moving subjects.

Video quality is okay in 4k. It looks reasonably sharp and detailed, but because the camera can only record cropped 4k, it's using a smaller portion of the sensor, resulting in slightly worse quality than you might expect for 4k. In low light, video looks quite noisy and grainy, and the camera has trouble bringing out detail in the shadows.

The PENTAX K3 III has two SD card slots, though only one is rated for faster UHS-II cards. It's still a welcome addition, and given the camera's limited buffer, the advantage of a UHS-II card is marginal. There are three different storage settings when two SD cards are inserted, including sequential, which switches to the backup after the card in Slot 1 is full, duplicate, which uses the second card as a running backup, or an option to store RAW and JPEG photos separately on each card.
