Best Pentax DSLRs of all time

In this guide, I’m going to be a purist and pick out solely the best Pentax DSLRs you can buy. Despite all the hype around mirrorless, DSLRs have many fans, with plenty of photographers preferring their optical viewfinders, rugged bodies and big batteries over mirrorless technology. It can be easier to pick up lenses more cheaply, too. Pentax is the only major camera manufacturers to have reaffirmed its commitment to DSLRs, with others jumping firmly into the mirrorless camp.

We’re not here to repeat the DSLR vs mirrorless debate. If you like the idea of shooting on a DSLR, Pentax is a great manufacturer to jump on board with, and you’ll find some top-notch cameras here, including recent models like the Pentax K-3 III Monochrome, released in 2023. Our focus on DSLRs means that a few recent Pentax releases are missing from the list – you won’t find the Pentax 17 point-and-shoot film camera, or any of the waterproof compacts like the Pentax WG-1000. You also certainly won’t see anything of Pentax’s brief foray into mirrorless with the ill-fated Pentax K-01. This all about the DSLR.

If you’re new to DSLRs (digital single-lens reflex cameras) in general, rest assured that Pentax is a fine choice, and our team has reviewed all the latest offerings from the manufacturer. Our selections are based on our extensive testing experience, and we’re confident that all the cameras on this list represent value for money. You also have the best Pentax lenses to choose from.

Best Pentax for black & white photography: Pentax K-3 III Monochrome

At a glance:

• $2,200 / £2,249 body-only
• 25.7MP APS-C sensor
• ISO 200-1,600,000
• 12fps continuous shooting
• 0.7x pentaprism viewfinder
• 3.2in, 1.62m-dot touchscreen
• 5-axis in-body image stabilisation

The Pentax K-3 Mark III was released by Ricoh as a high-end APS-C DSLR aimed squarely at enthusiast photographers. It turned out to be a very capable camera, combining fine handling, a robust build, and impressive image quality. The Pentax K-3 Mark III Monochrome combines the robust, enthusiast-friendly design of the K-3 Mark III with all the established advantages of a monochrome sensor: high pixel-level sharpness, low noise, end excellent dynamic range. 

At $2,200 / £2,249 the Monochrome model commands a premium over the stock Pentax K-3 Mark III at $1,700 / £1,899 body-only; but is dramatically cheaper than either of Leica’s current offerings, the Leica Q2 Monochrom ($6200 / £5200) and Leica M11 Monochrom ($6,195 / £5,300). It’s still not exactly a camera for the masses, but makes the idea of a dedicated mono model more accessible than before.

Best value Pentax camera: Pentax K-S2

At a glance:

• from $450 / £330 body-only (used)
• 20.2MP APS-C sensor
• ISO 100 – 51,200
• 0.95x pentaprism viewfinder
• 3in, 921k-dot touchscreen

Naming convention suggests that the Pentax K-S2 is a replacement for the popular entry-level K-S1; yet a glance at its specification reveals a more advanced camera likely to succeed the K-50. The K-S2 features a 20.1MP APS-C CMOS sensor which boasts an ISO range of 100-51,200 and has had the low-pass filter removed for maximum sharpness.

Any concerns about moiré and alias patterning are managed through the presence of an anti-alias filter simulator provided by the built-in image stabilisation system, which provides 3.5 stops of benefit as well as working with almost any lens including both wideangle and prime optics. Other features include in-camera Raw processing, HD video capture and built-in Wi-fi and NFC connectivity.

It could well be argued that the K-S2 is one of the most pleasing DSLRs to use thanks to its large viewfinder and impressive control set-up. Throw in the extensive range of compatible Pentax K mount lenses and you’ve got a camera which represents excellent value and is one of the best in its class.

Best Pentax for enthusiasts: Pentax KP

At a glance:

• from around $770 / £500 used
• 24.3-million-pixel APS-C sensor
• PRIME IV imaging engine
• Pentax K mount
• ISO 100-819,200
• 7fps continuous shooting
• 3.5mm headphone socket

The Pentax KP inherits features from the full-frame Pentax K-1 as well as the mid-range K-70 and targets keen enthusiasts who are committed to photography and insist on advanced features in a solid, weather-resistant body.

There is quite a lot to like about the KP. It has in-body stabilisation, the dynamic range is excellent for this size of sensor, it’s easy to use and the interchangeable grip design gives the user choice over the way the camera handles and feels with different lenses.

While it shoots slightly faster and offers a greater number of AF points than the K-70, it lacks a top-plate LCD, dual card slots, has a lower battery life and can’t shoot at 8.3fps.

Best Pentax for landscapes and portraits: Pentax K-1 II

At a glance:

• $1,697 / £1,899 body only
• 36.4MP full-frame
• 3.2in 1.04m-dot vari-angle-touchscreen
• Sensor-shift stabilisation & GPS
• Pentaprism OVF with 0.7x mag and 100% FOV
• Weather-resistant

If you want a full-frame DSLR with a Pentax badge on the front, the choice is very simple. There is only one series of full-frame DSLRs, comprising two iterations. The most recent Pentax K-1 II represented a modest upgrade from its predecessor the K-1, with the most notable improvement being the increased sensitivity by 2EV to a whopping extended ISO 819,200.

So what do the K-1 and K-1 II cameras have in common? Plenty of good things; a 36MP full-frame sensor with that excellent low light performance. A large pentaprism optical viewfinder (pentaprism is superior to pentamirror). Then there is sensor shift stabilisation, paired with GPS and a unique feature called Astrotracer that arguably makes the K-1 II the DSLR choice for astrophotography. There are also some great value, high quality Pentax K-mount lenses available, so landscape and portrait photographers are very well catered for.

Pentax has a tradition of well-made cameras – the brand would not have lasted so long otherwise. This flagship weather-resistant camera is the toughest of them all, and you feel it in every one of its 1010 grammes! We love the clever four-arm design of the vari-angle touch screen, plus the illuminated buttons are a nice touch for low light handling.

Have a look at the unique silver-edition of the Pentax K-1 Mark II and fitting lenses.

Best Pentax DSLR for action: Pentax K-3 III

At a glance:

• $1,697 / £1,899
• 25.7MP APS-C sensor
• ISO 100-1,600,000
• 12FPS
• 4K video up to 30p
• Pentaprism OVF with 1.05x mag and 100% FOV
• Weather-resistant

Pentax caused something of a stir by releasing a new DSLR in 2021, but as we found in our review, the Pentax K-3 III is a mighty fine flagship APS-C format camera, afforded a wealth of K-mount APS-C lenses and high performance. Features are too many to list here, but highlights include the back-illuminated sensor with maximum ISO 1,600,000 sensitivity, 12fps with 101-point AF system and, wait for it, 4K video! Yes Pentax can do video, too.

Handling-wise, high expectations are met. This is a solid weather-resistant camera weighing 820g. It has excellent ergonomics, dual card slots, a bright and large OVF, top LCD, though the 3.2in 1.62m-dot rear touch screen is fixed which is a shame. However, if you want a high performance Pentax DSLR for the likes of sports and wildlife and don’t mind the cost (at launch the K-3 III was more expensive than the full-frame K-1 II and rivals like the Nikon D500), then K-3 III is the choice for you.

Best Pentax DSLR for beginners: Pentax K-70

At a glance:

• $750 (new) / £350 (used)
• 24.2MP APS-C sensor
• 3in 921k-dot vari-angle screen
• Pentaprism OVF with 100% FOV
• Weather-resistant
• 6fps

Entry-level DSLRs don’t come any better than the Pentax K-70. In fact, the K-70 possesses plenty of qualities that even advanced photographers appreciate, such as a weather-sealed body, comfortable grip, and a bright pentaprism optical viewfinder with 100% field of view. You simply don’t get these sorts of features in similarly priced DSLRs. On the downside, it is larger and heavier at 688g when compared to other entry-level DSLRs.

For photographers, the innards of the K-70 are equally impressive; 24MP and a maximum ISO 102,400 with sensor-shift stabilisation, 6fps and built-in flash. Not forgetting its rugged build quality that is well suited to adverse outdoors conditions, and you have an all-purpose camera that is simply a great option to start out with DSLR photography. It’ll even provide on-screen prompts as you learn the ropes.

Best Pentax DSLR for detail: Pentax 645Z

At a glance:

• $4,996 / £4,500 new, from $3,300 / £1,500 second-hand
• 51.4MP medium format sensor
• ISO 100-204,800
• 3.2in 1.04m-dot tilt-LCD
• HD video up to 60fps
• 1550g (with battery and card)

The digital medium format market was disrupted through the introduction of the Pentax 645D in 2010. Not only did Pentax do away with the digital back, but also significantly undercut the big players Phase One and Hasselblad. At around a third of the cost, the 645D opened up digital medium format to a whole new group of photographers, and was eventually replaced by the Pentax 645Z in 2014.

What you get in the successor is a camera boasting a 51.4MP resolution on a 43.8×32.8mm image sensor, a tank-like build both in size and durability whereby you can confidently break free from the studio, plus a gorgeous viewfinder and handy tilt-LCD for waist-level shooting.

It’s a real shame that Pentax seemingly lost interest in its medium format DSLRs, and never felt the need to extend the lineup that is limited to six lenses, because it no longer enjoys predominance. Since the 645Z, Fujifilm launched its GFX range of cameras that includes the more cutting edge Fujifilm GFX 50S II, while Hasselblad added a more wallet-friendly lineup in the dazzling Hasselblad X1D series.

Best ultra-cheap: Pentax K100D

At a glance:

• 6.1MP APS-C CCD sensor
• ISO 200-3,200
• 2.5in 210k-dot LCD
• Sensor-shift stabilisation
• Discontinued 2007
• Around £50 second-hand

Sensor-shift stabilisation under the guise ‘Shake Reduction’ was introduced in the Pentax K100D and arguably set Pentax DSLRs apart for quite some time. Evolved to its current 5-axis form and compatible with a huge number of lenses, this feature paved the way for DSLR features unique to this very day, including Astrotracer (works with GPS), Pixel Shift and AA filter simulation.

As for the camera itself, the K100D has an 11-point AF array and optical viewfinder that would remain in Pentax APS-C DSLRs for many years, plus it boasts a top LCD which is usually found in high-end cameras only. Otherwise, the K100D understandably shows its years, with a CCD sensor, modest 6MP resolution, small LCD screen, 2.8fps drive mode, and it can’t shoot video. Still, you can pick up a K100D body only for around £50! The Pentax K100D Super, which was released at a later date, introduced a dust removal system, which is now standard across numerous other camera brands.

Best limited edition: Pentax K-x rainbow

At a glance:

• 12.4MP APS-C sensor
• ISO 200-6,400
• 2.7in 230k-dot LCD
• 720p video up to 24p
• RRP $649 but good luck finding one!

We can’t remember a DSLR that has been available in so many colours as the Pentax K-x, and the most memorable has to be the Pentax K-x rainbow edition. Made in collaboration with Tower Records and limited to 1,000 units, you’ll either want sunglasses as an accessory or for your own protection, depending which way you look at it. The camera’s styling is a matter of taste, but it certainly makes a statement.

Other than booting up with a rainbow image on the LCD (and its psychedelic shell), the rainbow edition is identical in every way to a standard Pentax K-x that harks back to 2010. That means you get a 12.4MP APS-C sensor, a decent OVF for the money, sensor-shift stabilisation, 4.7fps and, yes, video recording – gosh! It’ll be a mission to get your hands on the rainbow version, and you’ll have better luck if you like all-red.

Best second-hand Pentax under £1000: Pentax K-1

At a glance:

• 36.4MP full-frame sensor
• ISO 100-204,800
• 3.2in 1.04m-dot vari-angle-touch screen
• Sensor-shift stabilisation & GPS
• Around £1,000 / $1,000 second-hand

To its credit, there’s not a lot more to say about the Pentax K-1 that hasn’t already been said about the K-1 II above. Unless you are a serious low-light photographer, then the K-1 offers virtually everything that the K-1 II does but at a significantly lower price (though the K-1 is no slouch in low light either). At less than £1,000 second-hand, it’s such a compelling purchase.

Both cameras offer high levels of sharp detail thanks to a 36MP sensor with no anti-aliasing filter. Where there is a risk of aliasing artefacts, the anti-aliasing filter simulator can be called upon – a feature that is present thanks to sensor stabilisation. Both cameras are comfortable in the hand, albeit on the heavier side. Both cameras really make use of sensor shift stabilisation for unique shooting modes. Overall, you’ll struggle to find a more capable DSLR for photography at this price point.

Best Pentax bargain under £100: Pentax K-r

At a glance:

• 12.4MP APS-C sensor
• 3in 921k-dot LCD
• 720p video up to 25p
• Pentamirror OVF with 0.85x mag and 96% FOV
• 598g with battery and card
• Around £100 / $300 second-hand with lens

We’ve scoured second-hand stock held by reputable dealers in 2022 and the best Pentax camera you can snag sub-£100 is the Pentax K-r, where you’ll get the 18-55mm kit lens chucked in, too. It may have had a short 18-month shelf life being discontinued in 2012, but the K-r is a highly capable shooter considering its age.

With a 12.4MP APS-C sensor, extended ISO 100-25,600 range, an excellent choice of lenses, much improved LCD screen, a continuous drive mode of 6fps and 11-point AF system, the K-r is able to make excellent pictures for all types of photographers. Despite its more premium feel over the K-x, the K-r is not in fact weather-resistant, although a Li-ion battery was introduced whereas the K-x and other cameras from this era rely on AA batteries.

How to choose the best Pentax DSLR

When picking a Pentax DSLR, you’re choosing from three sensor sizes: APS-C, full-frame, and medium format. APS-C is the smallest, generally found in cameras pitched at beginners, while full-frame is the professional standard, producing better images, but costing more. You can learn more about the differences in our full run-down of APS-C vs full-frame. Medium format, meanwhile, is a larger sensor size, designed to capture unparalleled levels of detail. Pentax only made a couple of medium format DSLRs, but they’re still a worthwhile buy if you can find them.

Other specs to look at will depend on what you want to shoot. Pentax cameras are famous for good weatherproofing, so the brand in general will suit the outdoor photographer. Beyond that though, you may want to compare burst rates if you’re planning to shoot fast action, or ISO range if you want to photograph in low light (some Pentax DSLRs can go surprisingly high).

You may also want to look at which cameras have built-in stabilisation to keep shots blur-free at slower shutter speeds, and some have extra useful features like GPS. Finally, while no one would say it is Pentax’s forte, later cameras have been begrudgingly given the ability to shoot Full HD video, and even 4K video on the most recent offering.

FAQ: Does Pentax still make cameras?

Yes. The Pentax brand was purchased by Ricoh in 2011, and the firm has continued to release cameras under the Pentax branding to this day. Recent releases include the Pentax 17 film camera and Pentax WG-1000 waterproof camera in 2024, as well as the Pentax K-3 III Monochrome in 2023. While Pentax doesn’t release new cameras at the same frequency as many of its competitors, it is definitely still developing new cameras. Also, by virtue of staying out of the ultra-competitive mirrorless market, Pentax has been able to explore a few interesting niches of its own.

FAQ: Do old Pentax lenses fit on new Pentax cameras?

Yes. Pentax has shown impressive respect for its heritage in keeping its old lenses compatible with its newer bodies, and you shouldn’t have a problem fitting them. Just bear in mind that if you’re using an old lens from the film era, you won’t be able to take advantage of autofocus and will have to reacquaint yourself with manual focusing. On some bodies, you may need to set the camera to a specific ‘M’ mode to get things working.
