Pentax Q vs Samsung NX11: A Hands-On Deep Dive for Serious Buyers

Choosing between the Pentax Q and Samsung NX11 takes us back over a decade to when mirrorless cameras were just starting to carve out space in enthusiast and beginner hands alike. Both launched as entry-level mirrorless systems but took completely different routes – the Pentax Q really pushed miniaturization with a tiny sensor and ultra-compact lenses, while the Samsung NX11 flaunted a larger APS-C sensor and a more traditional DSLR-style body. Having spent many years testing thousands of cameras from the cheapskate compact shooters to pro-grade monsters, I’m excited to share a detailed comparison based on firsthand trials, technical analysis, and real-world use cases.

Whether you’re a portrait hobbyist, landscape lover, wildlife shooter, or content creator hunting for value on a budget, this guide will give you real, grounded insights - quirks, strengths, weaknesses and all. So pull up a chair; let’s get under the hoods of the Pentax Q and Samsung NX11.

First Impressions: Size, Style, and Handling

One look at these cameras gives you opposite vibes. The Pentax Q, with its delightfully diminutive frame, almost feels like a point-and-shoot that went to mirrorless school. Its rangefinder-style design is minimalist and ultra-portable, making it an excellent pocket rocket - especially for those who prize stealth and light kit loads.

The Samsung NX11 is more conventional with an SLR-inspired shape, complete with a pronounced grip and a heftier build. While not bulky by DSLR standards, it definitely clubs for your thumbs. The larger size gives it a more substantial feel and likely better ergonomics for extended shooting sessions.

Let's visually compare their sizes to give you a better feel.

The difference is obvious: the Q's compactness comes at the expense of a smaller sensor (more on that soon), while the NX11's size supports advanced handling features like a built-in EVF and superior balance with longer lenses.

From a usability standpoint, I found the Samsung’s traditional grip more comfortable during long hikes or events, but the Pentax Q scores points in situations where discretion and rapid travel are paramount. Bottom line? Your comfort and shooting scenario will heavily influence which body size feels right.

Design and Controls: The Camera at Your Fingertips

Ergonomics are not just size but how the controls work around the body. Both cameras have fixed 3-inch LCDs, but details differ, and their button layouts aim for distinct user experiences.

Let’s examine their top plate controls side-by-side.

The Pentax Q keeps things super simple, ideal for beginners or those who don’t want to fiddle with complicated menus. Its top has a straightforward shutter release, mode dial, and a few buttons - no clubs for your thumbs here.

In contrast, the NX11 is designed for those who want more direct access to exposure modes, ISO, and a bigger dial layout that doesn’t force you to dive into menus often. It also supports live view and video mode toggles conveniently.

On the rear, the Samsung’s bigger screen offers higher resolution, and the presence of an electronic viewfinder makes composing in bright conditions far easier than the Pentax Q’s LCD-only approach. More on that in the display section.

For grip, the NX11’s contours hold the hand well, especially when paired with bigger lenses. The Q’s minimal grip is fine for light use, but bigger hands may find it fiddly for prolonged sessions.

For tactile shooters, the NX11’s design wins usability points, but the Pentax Q appeals with simplicity and diminutive charm.

Sensor Tech and Image Quality Showdown

Now to the heart of the matter: image quality. This often defines the success and longevity of a camera system.

Here’s the direct sensor comparison highlighting size and technical details:

Pentax Q: It houses a tiny 1/2.3-inch CMOS sensor measuring just 6.17 x 4.55 mm - tiny when compared to modern mirrorless standards. While its 12 MP resolution is respectable, the physical pixel size is small, limiting its dynamic range and low-light performance. The 5.8x crop factor makes wide-angle shooting tricky unless you use specialized lenses.

Samsung NX11: Sporting an APS-C CMOS sensor (23.4 x 15.6 mm), it boasts a much larger sensor surface area - over ten times bigger than the Pentax Q’s. This yields significantly better image quality, higher dynamic range, and improved performance at higher ISOs. At 15 MP, it's slightly higher resolution, but the pixels are also physically larger, resulting in richer color depth, reduced noise, and smoother gradations.

From my lab testing (using DxOMark data as a reference and real-world shooting), the NX11’s sensor scores 63 on overall image quality, whereas the Pentax Q lags at 47. The color depth difference (22.7 bits vs 20.2 bits) and noise handling (low-light ISO of 553 vs 189) are particularly impactful when shooting portraits or dim environments.

For landscape shooters craving pristine files or astrophotographers pushing dynamic range, the NX11 is hands-down superior. The Pentax Q’s sensor is more limited, better suited to casual daylight shooting or scenarios where portability trumps pixel-peeping.

Viewing and Interface: LCDs, Viewfinders, and Menus

Composing your shot is an essential part of photography, so let’s talk about screens and viewfinders - no cameras are perfect, but these interfaces often make or break the experience.

The Pentax Q features a fixed 3-inch, 460K-dot TFT LCD. It’s bright enough for indoor use but harder to see clearly in strong sunlight, and sadly, the Q lacks any built-in viewfinder. This forces you to rely solely on the rear screen, which can feel limiting in bright outdoor conditions.

The Samsung NX11, however, packs a higher resolution 3-inch OLED screen with 614K dots, providing punchier contrast and better viewing angles. Importantly, it also boasts a built-in electronic viewfinder (EVF) with 100% coverage and 0.57x magnification, giving photographers a DSLR-like shooting experience with eye-level framing.

Here’s a side-by-side look at their LCDs for more clarity:

In practice, the NX11’s EVF shines in variable light - tracking your subject with compositional precision and reducing glare issues, especially useful for wildlife or sports photography where quick framing is key. The Pentax Q’s lack of electronic or optical viewfinder limits compositional stability, pushing users toward a more casual shooting style.

If you’re someone who shoots in bright outdoor scenarios or video, an EVF is a big productivity booster, and NX11 scores big here.

Autofocus, Shooting Speed & Burst Capability

For genres like wildlife, sports, or street photography, autofocus accuracy and continuous shooting speed can make or break a shot.

The Pentax Q uses contrast-detection AF with 25 focus points, no phase detection, and face detection is absent. It supports continuous autofocus and tracking but at a modest 2 fps burst rate - not fast by any standard.

The Samsung NX11 also employs contrast-detection AF but adds face detection for better portrait precision. However, it lacks phase-detection AF and does not support animal eye AF. Its continuous shooting maxes at 3 fps, slightly faster than the Q.

While these frame rates are modest compared to modern machines, the NX11 has the edge in more consistent autofocus performance thanks to face detection and a more developed AF system.

Here's a quick pros and cons list for AF and performance:

Pentax Q Pros:

• 25 AF points for decent coverage
• Sensor-shift image stabilization compensates for small sensor constraints
• Continuous AF and tracking available

Pentax Q Cons:

• No face or eye detection
• Slower burst rate at 2 fps
• Contrast-based AF struggles in low light

Samsung NX11 Pros:

• Face detection autofocus
• Faster 3 fps continuous shooting
• Electronic viewfinder aids focusing in difficult light

Samsung NX11 Cons:

• No phase-detection AF
• Lacks animal or eye AF technologies

For fast action or wildlife shooters, neither camera excels, but the NX11’s marginally faster burst and face detection make it a better choice. For street photographers favoring compactness, Q’s nimbleness could still prevail despite slower AF.

Lens Ecosystem and Focal Range Flexibility

A camera’s ecosystem often defines its usefulness long term. Let’s compare lenses and mount considerations for both systems.

• Pentax Q System: Features the Pentax Q mount with just 8 native lenses, largely compact pancake primes and zooms designed to match the small sensor. The focal length multiplier is a whopping 5.8x, drastically narrowing the angle of view and effectively pushing all lenses into telephoto territory. What’s wide-angle on the Q? You’re limited, so landscape shooters often feel constrained.

• Samsung NX11 System: Boasts a healthy 32 native NX mount lenses ranging from ultra-wide to telephoto primes and zooms with a moderate 1.5x crop factor. Samsung collaborated with lens makers like Schneider-Kreuznach for quality optics. This variety supports macro, portrait, landscape, and general purpose needs flexibly.

In practical terms, if you crave versatility in lens choices or specific focal ranges (especially wide angles), the NX11 shines. The Pentax Q might suffice for casual shooting but puts you in a tight spot if you want extensive experimentation with different focal lengths.

Build Quality, Weather Resistance & Battery Life

Neither camera was designed as a rugged outdoor companion, but a few points bear mentioning.

Build-wise, the Samsung NX11 is heavier at 499 grams, with a solid polycarbonate and metal mix that feels durable yet not overly bulky. Pentax Q comes in at a featherlight 180 grams, very travel-friendly but plasticky and less robust.

Neither camera offers environmental sealing, waterproofing, dustproofing, or shockproofing features. If you shoot in challenging weather, prepare to use protective gear or umbrellas.

Battery life is another everyday factor:

• Pentax Q: Rated at ~230 shots per charge using the D-LI68 battery.
• Samsung NX11: Much better endurance with ~400 shots per charge on the BP1130 battery.

Longer battery life on the NX11 means you can confidently shoot events or travel days without packing multiple spares. The Pentax Q needs more frequent recharges or piggyback batteries to keep up.

Video Capabilities: Not the Main Event but Worth Considering

Both cameras offer video, but neither as their main selling point.

• Pentax Q: Records Full HD 1080p (1920x1080) but capped at 30 fps. It uses MPEG-4 and H.264 codecs but lacks external microphone input or headphone jacks, limiting audio quality control. Stability is aided by in-body sensor-shift stabilization, which helps handholding.

• Samsung NX11: Maxes out at 720p HD video at 30 fps, also lacks professional audio I/O, and has no in-body stabilization. The video quality is serviceable but clearly less advanced than the Q’s.

If you require hybrid stills + video shooters for casual home movies or social sharing, the Pentax Q has the edge. Serious videographers will find both limiting and want to look elsewhere.

Final Verdict and Who Should Buy Which

We’ve covered nearly every angle, so here’s my no-nonsense rundown:

Parting Advice: Is It Time to Look Elsewhere?

Both cameras represent early-generation mirrorless tech; while they have quaint charm and pockets-only appeal (Pentax Q) or DSLR-like experience (Samsung NX11), I personally recommend newer models if your budget permits.

If you’re attracted by the Pentax Q’s tiny form factor, consider modern ultra-compact models with larger sensors (like Sony RX100 series). For Samsung NX11 fans, the NX20 and beyond offered solid upgrades, and today's entry-level APS-C smartphones and mirrorless models outperform these hand-me-downs at competitive prices.

Nonetheless, both remain interesting cameras for collectors, beginners with small budgets, or secondary travel companions.
