Today, we comprehensively compare two very different cameras aimed at distinct user bases: the Ricoh CX3 - a small sensor superzoom compact, and the Samsung NX30 - a more sophisticated APS-C advanced mirrorless camera. Drawing from extensive hands-on testing and industry-standard evaluation protocols, this article dives deep into their technical design, real-world performance, and value across all major photography genres, helping you make an informed decision based on your practical needs and budget.

Understanding the Design and Ergonomics: Who’s Comfortable in Your Hands?

The Ricoh CX3, with its compact and pocketable form factor measuring 102 x 58 x 29 mm and weighing 206g, epitomizes portability. Its compact body makes it ideally suited for travellers and street photographers valuing discretion and ease of carry. However, this small size comes with compromises: limited physical controls and no electronic viewfinder.

In contrast, the Samsung NX30 is a 127 x 96 x 58 mm, 375g mirrorless camera exhibiting an SLR-style body design, delivering a comfortable and substantial grip favored by enthusiasts and professionals who shoot extensively. This added bulk accommodates more advanced handling features such as more dedicated buttons, dials, and the inclusion of an electronic viewfinder (EVF). The ergonomics favor those who need prolonged use without fatigue and faster manual control access.

When assessing usability for extended sessions or professional workflows, the NX30’s robust design and richer tactile controls clearly outperform the CX3’s minimalist layout, which is geared more towards casual or compact carrying convenience.

Interface and Control: Intuitive Use vs. Sophistication

Comparing control layouts, the CX3 features a minimalist top plate - no top LCD or mode dial, with relatively fewer buttons and switchgear, reflecting its simplified operational ethos. The reliance on menus for exposure and white balance adjustments can be cumbersome for rapid shooting scenarios.

By contrast, the NX30 boasts a top plate replete with physical dials for shutter speed, exposure compensation, and dedicated buttons that enable quick settings adjustments, supporting advanced exposure modes including shutter priority, aperture priority, and full manual control. This is critical for photographers needing bespoke exposure fine-tuning and rapid responsiveness.

The inclusion of customizable buttons, a thoughtfully mapped joystick for AF point selection, and a fully articulated touchscreen on the NX30 dramatically improves interactive control, making it more appealing to users accustomed to DSLR-like precision interfacing.

Sensor and Image Quality: Small Sensor Compact vs APS-C Mirrorless

One of the most crucial factors impacting image quality is sensor size and technology. The Ricoh CX3 incorporates a 1/2.3" BSI-CMOS sensor measuring 6.17 x 4.55 mm (28.07 mm²) with a 10MP resolution (3648 x 2736 max). Although BSI design improves light sensitivity somewhat, the tiny sensor area inevitably constrains dynamic range, low-light performance, and overall image fidelity. The native ISO range of 80-3200 is limited, and there is no RAW support, forcing reliance on JPEG outputs that limit post-processing flexibility.

In stark contrast, the Samsung NX30 is built around a large APS-C CMOS sensor measuring 23.5 x 15.7 mm (369 mm²) with a 20MP resolution (5472 x 3648 max). The substantially larger sensor area introduces markedly improved light gathering, richer tonal gradation, and superior diffraction control at moderate apertures. This sensor supports ISO sensitivity up to 25600 natively, with excellent noise control validated by DxOMark-like benchmarks scoring 77 overall, 23.5 color depth, and a dynamic range over 12 stops.

Furthermore, the NX30 offers RAW capture, critical for professionals and enthusiasts who demand extensive image manipulation and color grading latitude in post-processing workflows.

For photographers valuing image quality paramountly - especially in landscapes, portraits, and professional settings - the NX30’s sensor is far superior. The CX3 caters more to casual use or situations where size constraints dominate over ultimate detail.

Viewing and Composition Tools: Fixed LCD vs Articulated AMOLED Touchscreen with EVF

The CX3 sports a fixed 3.0-inch LCD with 920k-dot resolution, providing a bright but non-touch, non-articulating interface. The lack of an electronic viewfinder means composition relies solely on the rear LCD, which can be challenging in bright outdoor conditions and less effective for stabilizing framing during telephoto shots.

The NX30 counters these limitations with a 3.0-inch fully articulated AMOLED touchscreen at 1036k dots, delivering vibrant colors and excellent contrast, facilitating high visibility under various lighting. The articulation is advantageous for creative angles and video recording. Crucially, the NX30 includes a 2.36M-dot EVF with 100% coverage and 0.66x magnification, providing precise framing and shooting stability, especially when using longer lenses or in low light.

Touchscreen AF control and menu navigation on the NX30 enhance responsiveness and ease of use, whereas the CX3’s button-based menu navigation feels dated.

Photography Styles Assessed Across Genres: Practical Strengths and Weaknesses

Portrait Photography: Skin Tone Reproduction and Bokeh Quality

The Samsung NX30’s larger sensor size combined with the extensive range of fast Samsung NX lenses (including f/1.4 and f/1.8 primes) allows for shallow depth-of-field effects with smooth, natural bokeh - ideal for isolating subjects. Advanced eye detection AF with face detection ensures precise critical focus in portraiture.

On the Ricoh CX3, with a small 1/2.3” sensor and slower zoom lens (f/3.5-5.6), background blur capability is inherently limited. Portraits tend to be more flat and less cinematic. Lack of face or eye detection AF hinders quick critical focusing on eyes, particularly in lower light or with moving subjects. Skin tones are decent but lack the subtle nuances offered by the NX30's superior sensor and 14-bit JPEG output.

Landscape Photography: Resolution, Dynamic Range, and Weather Resilience

Landscape photographers benefit from high resolution, wide dynamic range, and sturdy weather resistance. The NX30 shines here - 20MP APS-C resolution captures fine details, and the sensor’s dynamic range preserves highlight and shadow details essential for high-contrast scenes.
