Exploring the Pentax K-01 vs Pentax P80: Two Ways Into Photography Worlds Apart

When it comes to cameras, it’s easy to get swept away by the latest models boasting flashing specs and endless features. But sometimes, looking back at two markedly different cameras from Pentax - the mirrorless K-01 and the small-sensor compact P80 - reveals how form, function, and era shape photographic experience. I’ve tested both extensively, across genres from landscapes to sports, and I want to share a deep dive comparing these cameras from sensor tech to usability. Whether you’re a budget-minded hobbyist or a gear geek wondering about legacy Pentax, this guide will help you understand what each offers and who they’re really for.

Let’s start with the big picture: The K-01 debuted in 2012 as Pentax’s unique entry-level mirrorless with a retro SLR look and APS-C sensor, aiming for serious photographers open to manual control and interchangeable lenses. Meanwhile, the P80 - released three years earlier - is a compact point-and-shoot with a tiny 1/2.3" sensor and fixed zoom lens, built for convenience but limited in advanced capability.

You’ll find a lot here on image quality, autofocus, video, handling, and suitability by genre, plus real-world insights from my hands-on experience and thousands of test shots. Let’s jump in.

Size and Handling - Comfort Meets Portability

Starting with ergonomics, the difference is striking. The Pentax K-01 is significantly larger and heavier, weighing 561g with dimensions of 122 x 79 x 58 mm. Its solid body feels substantial in hand, sporting a robust plastic shell with unconventional angular lines designed by industrial designer Marc Newson. This styling choice is polarizing - some love the modern-retro charm, others find it bulky and less pocketable.

In contrast, the Optio P80 is a palm-sized compact weighing just 125g and measuring 102 x 59 x 25 mm, ideal to slip into a jacket pocket or small bag. It’s perfect for street photography or travel where discretion and minimal bulk matter most.

Handling the K-01 is a more serious affair - fully manual, with dedicated dials for shutter priority, aperture priority, exposure compensation, and ISO. It encourages deliberate shot-making. The P80 is designed for point-and-shoot simplicity, with fewer buttons and no dedicated exposure modes beyond basic automatic.

The K-01 also lacks a viewfinder entirely, relying on its 3-inch, 921k-dot TFT LCD for framing; the P80 similarly has no viewfinder but uses a smaller 2.7-inch, 230k-dot screen.

Controls on the K-01 are extensive but not overwhelming. Button placement is generally intuitive, though the lack of a built-in grip can affect comfort during longer shoots, especially with heavy lenses. Pentax’s focus here seems to have been on delivering manual control for enthusiasts on a budget.

On the P80, the limited control set can feel overly simplistic, with a small zoom rocker and a shutter button essentially driving all operations. No manual exposure modes mean less creative control.

Sensor and Image Quality - The Heart of Photography

Now to the core: image quality. The K-01 sports a 16MP APS-C CMOS sensor measuring 23.7 x 15.7mm, which is vastly larger than the P80’s tiny 12MP CCD sensor at just 6.17 x 4.55mm.

This size difference alone explains the K-01’s edge in noise performance, dynamic range, and overall sharpness. The APS-C sensor allows better low-light sensitivity (ISO max 12800 native) and richer color depth (DxO Color Depth can confirm values around 23.7 bits), while the P80 maxes out at ISO 6400 and struggles with noise beyond ISO 400 due to its smaller, less capable sensor.

The K-01 also benefits from sensor-based image stabilization, improving sharpness handheld and especially during macro or telephoto shooting. The P80, unfortunately, has no stabilization.

In practical terms, the K-01 produces images with significantly better detail retention, smoother tonal gradation, and wider dynamic range, crucial for landscape or portrait work where highlight and shadow detail matter most.

While the P80's sensor delivers decent images under good lighting, its limitations become pronounced in dim scenes or when you require tighter cropping.

Autofocus and Shooting Speed - How Fast and Accurate?

The K-01’s autofocus system is contrast-detection only - somewhat basic by 2012 standards - and lacks phase-detection or the sophisticated tracking capabilities found in newer mirrorless cameras. However, its 81 focus points do provide decent coverage for static subjects, and it supports face detection to help nail portraits.

Continuous shooting tops out at a respectable 6 frames per second (fps), though buffer limitations and slower write speeds can bottleneck action bursts. In practice, that’s decent for casual sports photography and wildlife snaps of somewhat predictable motion.

The P80, living up to its entry-level compact status, offers just a 9-point contrast-detection AF system and a maximum continuous shooting speed of only 3 fps. Autofocus can be sluggish, especially in low-light or moving subjects - no surprise there.

Neither camera supports advanced features like animal eye-detection or subject tracking, which limits their utility for serious wildlife or fast-paced sports shooting.

Build Quality and Weather Resistance

Neither the K-01 nor P80 offer weather sealing, a limitation for landscape and outdoor enthusiasts who shoot in less-than-ideal conditions. The K-01’s body is reasonably solid plastic but not ruggedized - care is needed in rough environments.

Similarly, the P80’s compact chassis is lightweight plastic without any environmental protections.

For outdoor photographers who prioritize durability, you’ll want to consider this carefully. The K-01’s interchangeable lens mount offers some access to Pentax lenses with sealing (depending on the lens), but the body itself remains vulnerable.

Lens Ecosystem and Compatibility - Expanding Creative Horizons

One of the K-01’s most compelling advantages is its Pentax KAF2 mount, compatible with an extensive array of 151 lenses (from prime classics to zooms, macro, ultra-wide, and telephotos). This depth of lens choice, often at attractively affordable prices on the used market, bestows enormous creative latitude.

The P80, of course, comes with a fixed lens - 28-110mm (full-frame equivalent 28-110mm * 5.8 crop factor puts it around 162-638mm approx) - with an aperture range of f/2.6-5.8. This lens is fine for casual shooting but cannot match the optical quality, aperture control, or specialized options lenses bring on the K-01.

If you’re someone who likes to tinker with focal lengths or experiment with bokeh effects and subject isolation, the K-01’s mount is a huge selling point.

LCD Screen and Interface - What Will You See?

The K-01’s 3-inch fixed TFT LCD with 921k dots is crisp, bright, and offers live view functionality. Color accuracy and visibility in sunlight are passable but not exceptional. User interface navigation feels vintage and menu-heavy but is manageable after some time.

The P80’s smaller and lower-resolution 2.7-inch LCD at 230k dots displays images and menus clearly enough for casual shooting but lacks finesse or touchscreen convenience.

Neither camera offers touchscreen controls, and neither has an electronic viewfinder, which some photographers miss during extended shoots or bright outdoor conditions.

Video Recording - What Can They Capture?

Video-wise, the K-01 supports Full HD 1080p recording at 30, 25, and 24 frames per second, encoding via MPEG-4/H.264. It lacks 4K or advanced codecs but does include a microphone input for better sound capture, an advantage if you want to shoot vlogs or events with decent audio.

The P80, meanwhile, maxes out at 720p HD video at 30fps. It records in Motion JPEG format, which offers lower compression efficiency and larger file sizes, and has no microphone port. Video quality is consequently unimpressive by today’s standards.

Neither camera features in-body image stabilization during video, but the K-01's sensor stabilization may help handheld clarity to some extent.

Battery Life and Storage - How Long Can You Shoot?

The K-01 uses a D-LI90 rechargeable battery that delivers about 540 shots per charge - a solid figure for mirrorless cameras of its time. You can expect a full day of moderate shooting before needing a recharge.

The P80’s D-LI68 battery and official battery life are not well documented, but small compacts of this era typically manage 200-300 shots. It’s fine for casual outings but less suited for intensive shooting days.

Both cameras accept SD, SDHC, and SDXC cards, and the K-01 has a single card slot.

Wireless Connectivity and Ports

Neither camera has wireless features such as Wi-Fi, Bluetooth, or NFC - unsurprising given their release dates.

They both offer micro HDMI output, and the K-01 doubles with a microphone input jack, while the P80 does not.

USB 2.0 ports enable image transfer but lack fast transfer speeds now common in newer models.

Performance Summary and DxOmarks

The K-01 has a DxO overall score of 79, indicating competent sensor performance with good color depth and dynamic range. The P80 was not tested by DxO, but based on sensor specs and pixel size, it ranks well below the K-01.

Genre-specific strengths show the K-01 is versatile enough for portraits, landscapes, and hobby wildlife shooting, albeit with autofocus limits. The P80 fits casual snapshots and travel ease, not demanding disciplines.

How Do They Handle Different Photography Styles?

Portraiture

For portraits, the K-01 shines with its larger sensor delivering creamy bokeh and smooth skin tones. Its face detection autofocus helps, though the contrast AF can struggle in dim light.

In contrast, the P80’s small sensor and slower lens mean less depth separation, flatter bokeh, and limited control. Skin tones tend to be less nuanced due to reduced dynamic range.

Landscape Photography

Landscape shooters will appreciate the K-01’s APS-C sensor capturing more detail and dynamic range. The ability to attach specialized wide-angle or fast prime lenses is another boost.

The P80, while ultra-portable, lacks resolution and has limited dynamic range, resulting in less detailed skies and shadows.

Wildlife and Sports

Neither camera is a wildlife or sports powerhouse, but the K-01’s faster continuous shooting and broader lens compatibility give it more chance to deliver. Its burst speed of 6 fps can track slower animals or casual sports.

The P80’s sluggish autofocus and 3 fps speed hinder capturing action, making it mostly suitable for static subjects.

Street Photography

Here the P80’s ultraportability is an asset - the tiny size and discreet design make it a stealthy companion.

The K-01 is bulkier and more conspicuous but offers creative flexibility and manual control if you don’t mind the larger footprint.

Macro and Close-Up

The K-01, when paired with dedicated macro lenses and with sensor-shift stabilization, can produce sharp close-ups.

The P80’s fixed lens can focus down to 10cm, good for casual macro but limited in magnification and detail.

Night and Astrophotography

The K-01’s greater ISO performance and longer shutter speeds (max 30sec) enable night shots and basic astrophotography.

The P80’s noisier images and ISO limitations reduce quality for low-light.

Video Production

Again, the K-01’s Full HD and mic input outscore the P80’s 720p and no audio input.

Though neither camera is video-centric, the K-01 edges ahead for hybrid shooters.

Travel and Everyday Use

For travel, the P80’s small footprint, light weight, and decent zoom make it an attractive grab-and-go camera.

The K-01 is less convenient but great for those who prioritize image quality and lens versatility.

Professional and Workflow Considerations

Neither is a professional standard camera, but the K-01’s RAW support, manual controls, and better sensor quality enable more serious editing workflows.

The P80’s lack of RAW and limited controls restrict professional use.

Value and Recommendations

At about $899 new (though now often found used cheaper), the K-01 offers impressive APS-C image quality and extensive lens options for enthusiasts willing to invest.

The P80, at $199, is an affordable compact for casual shooters wanting a simple, pocketable camera but with significant image quality compromises.

If you want a fun, manual, and highly flexible system with room to grow, the K-01 is my pick. If size and simplicity rule your priorities and image quality isn’t critical, consider the P80.

Final Thoughts: Know Your Needs First

What struck me most during testing is how differently these cameras approach photography: the K-01 as a platform encouraging creativity and manual input, the P80 as a simple snapshot machine.

If reviewing my sample images (taken side by side), you can see how sensor size translates into richer detail and color on the K-01, especially under challenging lighting.
