Pentax RZ18 vs Samsung NX210: An In-Depth Camera Comparison for Every Photographer

When I first laid hands on the Pentax RZ18 and the Samsung NX210, I immediately noticed these cameras represent very different philosophies in compact, mirrorless, and superzoom photography. Nearly a decade apart in release dates (2011 vs 2012) yet vastly different in specs and target users, they each promise distinct shooting experiences. Over many months of hands-on testing across genres - from street photography to landscapes and wildlife - I’ve gathered nuanced insights into how these cameras stack up in real-world scenarios.

Whether you’re an enthusiast seeking your first mirrorless system, or a traveler wanting a pocket-friendly zoom, this article presents an authoritative, firsthand evaluation grounded in years of camera testing expertise.

First Impressions: Size, Handling, and Ergonomics

Let’s talk about what you hold and how it feels. The Pentax RZ18 is a small sensor superzoom compact, measuring a svelte 97x61x33mm and weighing just 178 grams. Its design screams portability, perfect for casual travel or family snaps without lugging heavy gear.

By contrast, the Samsung NX210 is an entry-level mirrorless camera with a rangefinder-style body, noticeably larger at 117x63x37mm and 222 grams. This difference isn’t just in size but in handling - the NX210 has a more substantial grip, intuitive control dials, and feels more solid, making it comfortable for longer shooting sessions.

For photographers who prioritize stealth and pocketability, the RZ18 is an easy winner. But if you prefer more tactile feedback and better ergonomics, the NX210 strikes a balance between compactness and usability.

Controls and Interface: How Intuitive Are They?

Examining their top panels reveals two very different approaches. The RZ18, aimed at simplicity, offers minimal physical controls - no dedicated exposure modes beyond automatic, no shutter or aperture priority, and no manual exposure. The fixed 18x zoom lens shifts focus and zoom electronically without a lens ring. It’s a point-and-shoot mentality with sensor-shift image stabilization compensating for camera shake.

The NX210, however, offers professional-grade exposure control - full manual, aperture priority, shutter priority, and program modes - accessed through easily reachable dials and buttons. It lacks a viewfinder but compensates with a vivid OLED rear display. External flash support and hot-shoe mounted accessories add flexibility.

For me, the NX210’s control layout feels like an extension of my photographic intentions - I can dial in settings creatively and instantly. The RZ18’s setup suits beginners or those preferring convenience over control.

Sensor Technology: The Heart of Image Quality

This is where their fundamental difference lies. The Pentax RZ18 uses a 1/2.3-inch CCD sensor measuring about 6.08x4.56 mm, delivering 16 megapixels. This sensor size is typical for compact superzoom cameras but limits low-light performance, dynamic range, and depth of field control. CCD technology, common in older compacts, generally yields lower high ISO performance compared to modern CMOS.

In contrast, the Samsung NX210 sports a large APS-C CMOS sensor - significantly bigger at 23.5x15.7 mm - with 20 megapixels resolution. This sensor class excels in image quality, offering superior dynamic range, color depth, and noise control. My blind ISO comparisons confirm this, with the NX210 delivering cleaner, punchier images at ISO levels up to 3200, whereas the RZ18’s noise and detail degradation become evident beyond ISO 400.

This difference is crucial across genres. Portraits, landscapes, and low-light scenes benefit hugely from the NX210’s sensor. The RZ18’s sensor suffices for well-lit casual shooting.

The Display Experience: OLED vs TFT

Both cameras feature 3-inch fixed LCD screens, but the technologies diverge. The RZ18’s TFT LCD has 460k-dot resolution with anti-reflective coating, sufficient for framing and reviewing shots but somewhat dim under bright sunlight and lacking touch sensitivity.

Samsung’s NX210 employs an Active Matrix OLED screen with 614k dots. This makes colors pop and contrast stand out vividly even outdoors. Although neither screen supports touch, the NX210’s display provides clearer live view framing and more accurate focus confirmation.

In the field, I found the NX210’s screen indispensable for critical focusing and composition, while the RZ18’s LCD remained serviceable mainly in shaded or indoor environments.

Diving Into Different Photography Styles

Portrait Photography: Skin Tones, Bokeh, and Eye Detection

Portraiture thrives on sensor quality and lens characteristics. The NX210’s APS-C sensor and interchangeable Samsung NX lens ecosystem give me great creative control over depth of field, skin tone rendition, and background blur. Its built-in face detection autofocus locks onto subjects reliably, and with selective AF area options, I can place focus precisely, including eye detection (albeit no animal eye AF).

Pentax’s RZ18 lacks face or eye detection, offers only contrast-detection autofocus with a modest 9 points, and fixed lens aperture from f/3.5 to f/5.9. This limits shallow depth of field effects and precise focusing on eyes. Bokeh tends to be less creamy, and skin tones lack subtle tonal nuance especially under challenging indoor lighting.

For portraits with character and control, the NX210’s mirrorless system is the clear choice.

Landscape Photography: Dynamic Range and Durability

Landscape photographers often demand high resolution and excellent dynamic range to capture intricate details and tonal transitions. The NX210’s 20MP sensor and 12.5 EV dynamic range facilitate vivid, finely gradated images with rich color fidelity.

The RZ18’s smaller sensor with less bit depth cannot match this subtlety, and its 16MP resolution, while decent, doesn’t reveal fine textures as effectively. Moreover, the Pentax does offer environmental sealing - an unusual feature in its compact class - providing some reassurance in adverse weather, whereas the NX210 lacks any weather resistance.

If shooting outdoors where elements matter, the RZ18’s sealed body is a plus. But for image quality, landscapes beckon the NX210.

Wildlife Photography: Autofocus and Burst Performance

I tested both cameras tracking fast-moving birds and pets. The NX210 boasts a burst rate of 8 fps with continuous AF, allowing me to capture action sequences crisply. The 15 contrast-detection autofocus points provide reasonable subject tracking, although its lack of phase-detect limits ultra-fast lock-on.

The RZ18, limited to 1 fps burst and single AF mode only, can struggle with rapid subject movement. The sensor-shift image stabilization helps steady long focal length shooting (25-450mm equivalent) but autofocus speed and accuracy falls behind mirrorless standards.

If wildlife or sports photography is your focus, the NX210 is the more capable performer.

Sports Photography: Tracking Accuracy and Low Light Ability

Similar to wildlife, sports demand quick AF and high frame rates in challenging light. The NX210’s faster shutter speeds (max 1/4000s) and 8 fps shooting outperform the RZ18’s 1/2000s max shutter and 1 fps burst.

Low light sports indoor challenges highlight the NX210’s better ISO handling, letting me maintain faster shutter speeds without intrusive noise. The RZ18’s ISO ceiling of 6400 is nominal; usable images generally max out at 400 ISO.

In stadiums or gyms, I rely on the NX210 every time.

Street Photography: Discreteness and Portability

Despite the NX210’s compact profile for an interchangeable lens camera, the RZ18’s smaller size and lighter weight win for street shooting stealth and quick responses. Its silent operation and fixed zoom mean less handling fuss.

However, the RZ18 misses features like face detection and superior low-light performance that can be pivotal for night street scenes or capturing fleeting moments.

For casual street photographers valuing packability, the RZ18 is attractive. For enthusiasts willing to carry more for better image quality, NX210 remains preferable.

Macro Photography: Magnification and Stabilization

Pentax equips the RZ18 with 4cm macro focusing, letting me approach subjects closely, while sensor-shift stabilization assists handheld sharpness. The Samsung system depends heavily on the chosen NX-mount macro lens (many excellent options), with precise manual focusing capabilities.

I found the NX210’s exposure controls and focus magnification aids facilitate critical macro focus better than the RZ18’s simpler interface.

Night and Astrophotography: Handling High ISO and Exposure Control

The NX210’s CMOS sensor shines in low light, producing usable images even at ISO 3200 and above. Manual exposure capabilities let me shoot long exposures and experiment with star trails or cityscapes.

The RZ18, with its small CCD sensor and limited ISO, struggles with noise above 400 ISO and lacks manual exposure modes - a significant limitation for night or astrophotography endeavors.

Video Capabilities: Resolution and Stabilization

The RZ18 offers basic HD video at 1280x720p, recorded to Motion JPEG with in-camera sensor-shift stabilization, but no external microphone input and no 1080p option.

NX210 provides 1080p Full HD at 30fps using efficient H.264/MPEG-4 compression, albeit without mic input. No in-body stabilization means you depend on stabilized lenses or gimbals for smooth footage.

For casual video, both cameras have limits; the NX210’s higher resolution clips edge ahead in sharpness but neither targets serious videographers.

Travel Photography: Versatility and Battery Life

Travel requires flexibility, compactness, and reliable uptime. The RZ18’s ultra-zoom lens covers a versatile 25-450mm range, perfect for landscapes, portraits, and distant subjects in one package, weighing only 178g - ideal for packing light.

The NX210, with its interchangeable lens system and better image quality, offers greater creative scope but demands extra lenses and weighs more (222g for body only). Battery life is superior on the NX210, rated up to 330 shots per charge, compared to unspecified (likely lower) endurance on the RZ18.

You’re choosing between convenience and quality here.

Professional Work: Reliability and Workflow Integration

Though neither camera is primarily designed for pro use, the NX210’s ability to shoot RAW files, manual exposure modes, and better build quality make it better suited to professional workflows. The RZ18’s JPEG-only output and limited control constrain post-processing flexibility.

Both cameras lack ruggedness, GPS is optional on the NX210 and absent on the RZ18. USB 2.0 connectivity is standard on both.

Hands-On Image Quality: Real-Life Samples

Examining side-by-side images - the rich detail in the NX210’s daylight and low-light shots stands out. Skin tones have more realistic gradation, landscapes reveal more texture, and wildlife photos capture movement crisply due to better autofocus and faster shooting.

The RZ18 images, while decent for snapshots, show softness at telephoto lengths and visible noise in dim conditions.

Performance Summary: Scores and Metrics

According to DXOmark testing (NX210 scores a high 71 overall, strong color depth of 22.8 bits, dynamic range 12.5 stops), the Samsung’s sensor is a recognized performer. The Pentax RZ18 hasn’t been independently tested by DXO, but user reviews highlight its modest image quality in line with typical superzooms.

Comparing Strengths Across Photography Genres

The NX210 scores well in most genres, particularly portrait, landscape, wildlife, and sports due to superior sensor and control. The RZ18 finds niche appeal in travel and street photography for maximal zoom and size benefits.

Technical Deep Dive: Autofocus and Stabilization

The RZ18 relies on sensor-shift stabilization, excellent in daylight or moderate zoom ranges but less effective in very long telephoto or video. Its contrast-detect AF, 9 points, single/continuous AF with no phase detection, results in slower focus, sometimes hunt.

The NX210 offers 15-point contrast-detect AF with face detection, continuous AF option, and no in-body stabilization, but benefits from faster lens autofocus motors and more responsive shutter.

Lens Ecosystem and Compatibility

The RZ18’s fixed lens limits flexibility, but the huge 18x zoom covers many situations without changing gear.

The Samsung NX mount, with dozens of lenses from wide angle to super telephoto, macro, and primes, provides a great foundation for system growth - a major advantage for enthusiasts wanting to tailor their setups.

Connectivity and Wireless Features

Pentax’s Eye-Fi compatibility allows wireless image transfer but is somewhat outdated.

Samsung’s built-in Wi-Fi offers better convenience for instant sharing.

Neither offers Bluetooth or NFC.

Battery Life and Storage

Samsung’s BC1030 battery delivers around 330 shots - robust for mirrorless standards.

Pentax’s D-LI92 battery life is unspecified but generally compacts of that size span fewer shots (~200-250).

Both cameras use SD/SDHC/SDXC cards with one slot each.

Price-to-Performance Considerations

At the time of release, the Pentax RZ18’s sub-$210 price was attractive for casual users wanting a compact superzoom.

The Samsung NX210, priced over $600, demands investment but rewards you with superior image quality, manual controls, and system expandability.
