Samsung NX5 vs Sony RX100 II: A Hands-On Comparison for Photography Enthusiasts

Choosing a camera that fits your photography style, budget, and ergonomic preferences can be a daunting task given the sheer variety available. Today, I’ll walk you through a detailed comparison between two vastly different yet interesting models: the Samsung NX5, an entry-level mirrorless system camera announced back in 2010, and the Sony Cyber-shot RX100 II, a high-end large-sensor compact released in 2013. Both cameras are notable in their categories, but they cater to different priorities. From sensor technology and lens ecosystems to real-world performance in various photography disciplines, this comparison will help you understand which camera suits your needs and why.

Having personally tested thousands of cameras over 15 years, I’ll also share insights grounded in practical experience and hands-on testing methodologies - things not obvious from specs alone. Let’s start by placing these two contenders side-by-side in terms of size and handling.

Handling and Ergonomics: Bigger Isn’t Always Better

At first glance, the Samsung NX5 is a classic SLR-style mirrorless camera with a solid, boxy body, whereas the Sony RX100 II is a pocket-friendly, rangefinder-style fixed-lens compact. Their physical dimensions and weights illustrate this well: the NX5 measures 123x87x40 mm and weighs 499 grams, while the RX100 II is significantly more compact at 102x58x38 mm and lighter at just 281 grams.

For photographers used to traditional DSLR ergonomics, the NX5 feels more “camera-like,” with a pronounced grip that desks you well for extended shoots. The larger body makes button placement more spacious - easing access but perhaps intimidating beginners with fewer tactile controls. By contrast, the RX100 II emphasizes portability: its sleek outline fits comfortably in a jacket pocket or small bag without added bulk.

If portability ranks high on your list - say, for travel or street photography - the RX100 II’s compactness wins hands down. However, if you shoot for longer hours or require sturdier handling for telephoto lenses, the NX5’s body offers more secure grip and physical controls, albeit less refined by modern standards.

Top Controls and User Interface: Balancing Simplicity and Function

Examining the control layouts from above reveals key differences: the NX5's top plate features a mode dial, shutter button, and pop-up flash with classic DSLR resemblance, while the RX100 II swaps the traditional mode dial for a more compact control ring around the lens (for zoom/focus) and a minimalist design.

The NX5 includes dedicated buttons for exposure compensation, a customizable function button, and a physical flash hot-shoe compatible with external units - a boon for creative lighting setups. Although the RX100 II has a built-in flash and supports an optional electronic viewfinder accessory, it lacks a native hot-shoe, limiting flash flexibility.

Both cameras feature shutter speed dials (though the RX100 II’s is mostly electronic), but the NX5 supports shutter speeds up to 1/4000s, giving a slight edge for capturing fast action or shooting wide apertures in bright daylight. The RX100 II maxes out at 1/2000s, adequate for most scenarios but potentially limiting in high contrast outdoor conditions.

In real-world use, I find the NX5's button layout a bit dated but effective; the RX100 II excels at quick menu navigation with a sharp screen but demands menu diving for some settings. Hence, for those who want a tactile shooting experience with physical dials, NX5 remains preferable. On the flip side, RX100 II’s interface caters better to casual shooters valuing speed over granular control.

Sensor Size and Image Quality: The Heart of the Capture

Here’s where the comparison gets really interesting. The Samsung NX5 sports an APS-C CMOS sensor measuring 23.4x15.6 mm (approx 365 mm²) with 15 megapixels. The Sony RX100 II, meanwhile, incorporates a smaller but technologically advanced 1-inch CMOS sensor sized 13.2x8.8 mm (116 mm²) yet offering 20 megapixels.

Common wisdom suggests that larger sensors generally produce better image quality - especially at higher ISOs - due to bigger photosites capturing more light. And here, the NX5 slightly edges out thanks to its APS-C sensor area nearly 3x larger than RX100 II’s 1-inch chip. However, ISO performance and dynamic range depend heavily on sensor generation and image processing.

Testing these cameras side by side, I noticed the RX100 II's sensor uses Sony's BSI (Backside-Illuminated) technology, which enhances light gathering despite the smaller size. This gives RX100 II a leg-up for low-light photography and cleaner high ISO results up to ISO 3200–6400 range. NX5 tops out at ISO 3200 native, but grain becomes apparent beyond ISO 800–1600 on my real-world tests.

Image sharpness is quite different too. The RX100 II’s higher megapixel count - 5472x3648 max resolution - translates to denser details for landscape or macro shots, albeit with a tighter field of view caused by a 2.7x crop factor from its fixed 28-100mm equivalent lens. The NX5’s APS-C sensor plus Samsung NX mount offers a 1.5x crop factor but you have interchangeable lenses, making focal length choices far more flexible.

Both cameras employ an anti-aliasing filter to curb moiré but at the expense of the sharpest possible image fine detail. The RX100 II tends to produce crisper JPEGs out-of-camera, partly due to better image processing pipelines, while the NX5 benefits from RAW support for post-processing but usually requires more tweaking.

In conclusion, if ultimate image quality in low light matters to you, RX100 II’s sensor technology rivals or even surpasses the older NX5 despite smaller size. But if you’re after flexibility in lenses and larger sensor area for more control over depth of field, the NX5 brings unique value.

Rear LCD and Electronic Viewfinder: Visibility Matters

Both cameras have 3-inch rear displays, but the specs and usability vary substantially. The NX5 uses a fixed active matrix OLED screen with a resolution of 230K dots, which today feels quite low in clarity and sharpness. The display is bright and color accurate but small pixel density limits detailed review on location.

The Sony RX100 II employs a 3-inch tilting Xtra Fine WhiteMagic TFT LCD boasting 1229K dots resolution - around 5x the effective pixel density of the NX5. This makes it effortless to check focus, framing, and exposure in much more detail. The tilting mechanism also aids shooting at awkward angles, something the fixed NX5 cannot match.

While the NX5 features an electronic viewfinder with 100% coverage and 0.57x magnification, it lacks resolution details and doesn’t impress by modern standards. The RX100 II does not have a built-in EVF but supports an optional accessory hot-shoe-mounted OLED EVF, which many users find cumbersome but handy in bright conditions.

From real usage, I’d rank the RX100 II’s rear LCD as far superior for composing and reviewing shots, with NX5’s viewfinder serving as a fallback. If you particularly dislike composing on LCDs and prefer a sturdy EVF, the NX5’s built-in EVF gives an advantage despite modest specs.

Lens Ecosystem and Optical Versatility

One indisputable advantage of the Samsung NX5 is its mount system: Samsung NX lens mount with approximately 32 native lenses available, ranging from super-wide zooms to fast primes and telephotos.

Given the APS-C sensor size, these lenses offer good aperture ranges (many f/1.8 to f/4 options), helping portrait and low-light performance. The ability to switch lenses - manual or powered focus - makes the NX5 adaptable across many photography disciplines, from macro to wildlife.

On the other hand, the Sony RX100 II sports a fixed 28-100mm equivalent zoom lens with a relatively bright f/1.8-4.9 aperture range. This lens provides remarkable convenience without needing lens changes and is optically sharp, especially at wider focal lengths. It covers wide to telephoto ranges ideal for travel and street photography but falls short if you want specialized optics like macro or super-telephoto reach.

There's built-in optical image stabilization on the RX100 II lens element, helping handheld low-light and video shoots - a critical feature missing from the NX5 which relies solely on lens-based or no stabilization.

If you value interchangeable lenses and longer-term growth, the NX5 is your ally. For all-in-one simplicity, pocketability, and decent zoom flexibility, the RX100 II shines.

Autofocus Performance: Speed, Accuracy, and Tracking

The NX5 uses a contrast-detection AF system with 15 focus points, including face detection but no eye or animal eye autofocus capabilities. It supports single, continuous, and selective AF modes but lacks phase-detection and AF tracking, which limits performance for sports or wildlife action.

In contrast, the RX100 II employs a 25-point contrast detection AF system with sophisticated face detection and tracking capabilities, including continuous AF tracking. While not as fast as phase-detection AF in flagship mirrorless cameras, its AF speed and accuracy impressed me for a compact camera. It offers reliable focus lock even for moving subjects in well-lit conditions.

Shooting bursts reveals stark differences too: the NX5 manages roughly 3 fps continuous shooting, while the RX100 II can shoot up to 10 fps - a decisive edge for sports, wildlife, or fast-moving street moments.

For photographers prioritizing autofocus speed and tracking - think sports, wildlife, or event photography - the RX100 II delivers noticeably better performance. The NX5 suits more static subjects or deliberate compositions.

Burst Rates, Shutter Speeds, and Flash

Burst capability is crucial for capturing peak moments. The NX5’s 3 fps won’t satisfy dynamic shooting styles, whereas RX100 II’s 10 fps rate approaches DSLR speeds of the era.

Max shutter speeds also differ: 1/4000s on NX5 allows freezing extremely fast motion or wide aperture shooting in bright light; RX100 II caps at 1/2000s, sufficient for most but slightly limiting under strong sunlight.

Both offer built-in flashes: the NX5’s 11-meter range and flexible modes (red-eye reduction, fill flash, manual) provide more creative options versus the RX100 II’s simpler 15-meter auto flash with slow sync but fewer modes.

The NX5 has a hot-shoe for external flashes, a definite advantage for studio or event photographers who want control over lighting. The RX100 II lacks a built-in hot-shoe; external flash use demands adapters or is impossible.

Video Capabilities: Are They Relevant for You?

Video has become a core consideration even for still photographers. The Samsung NX5 records HD video at 1280x720p 30 fps with basic H.264 codec. It does not support Full HD 1080p or higher frame rates, nor does it have microphone or headphone jacks. Video is a secondary feature.

Sony RX100 II ups the stakes with Full HD 1080p at 60 fps support, AVCHD and MPEG-4 formats, and built-in optical stabilization that stabilizes handheld footage effectively. However, it also lacks external mic and headphone ports - a common compromise in compact cameras.

If video is a priority - especially quality and stabilization - the RX100 II offers a more modern and capable package. For those focused primarily on stills, the NX5 suffices but doesn’t impress for video work.

Specialized Photography Disciplines: Who Excels Where?

Let’s break down how each camera performs across key photography genres and use cases based on my extensive testing:

• Portraits: The NX5’s APS-C sensor and interchangeable lenses (with fast primes) give greater control over skin tones, shallow depth of field, and bokeh quality. However, autofocus lacks eye detection, meaning you’ll need patience and skill for critical focus. RX100 II’s lens isn't as fast but has face detection AF, supporting accurate eye-level focusing. I lean toward the NX5 if lens options and bokeh matter most.

• Landscapes: The NX5’s larger sensor aids dynamic range, but RX100 II’s higher resolution and modern sensor tech produce sharper, cleaner daylight images. Lack of weather sealing on both is notable, but manageably so for amateurs. The RX100 II’s compact size and tilt screen help low-angle shots in the field. Result: tie with an edge to the NX5 for sensor size and lenses.

• Wildlife & Sports: RX100 II’s faster burst rate, superior autofocus tracking, and compact size enable better quick-response shots despite limited telephoto reach. NX5’s slower 3 fps and AF limitations restrict catching action but allows deeper telephoto shooting with optional lenses if you can lug them around.

• Street Photography: Portability and discretion matter here. The RX100 II’s pocket size, quiet operation, and rapid AF make it perfect, while the bulkier NX5 may attract attention and slow you down.

• Macro: NX5 benefits from specialized macro lenses with precise focus control, while RX100 II offers respectable close focus at 5 cm with in-lens macro mode. If macro is your passion, NX5 lens system wins for versatility.

• Night / Astro: RX100 II’s BSI sensor and better high ISO capabilities outclass the older NX5 sensor here, plus longer exposure modes observed on Sony cameras aid astrophotography.

• Travel: RX100 II is the clear winner for travelers seeking lightweight gear with solid all-round performance and built-in zoom lens. NX5 could be cumbersome for casual travel due to size and interchangeable lenses.

• Professional work: The NX5’s APS-C RAW files offer more latitude for post-processing and integration into workflows, but lack rugged build quality and modern AF. RX100 II leans more consumer compact, limiting professional usage.

To further clarify these performance nuances, here are sample images from both cameras illustrating their output before we judge final ratings.
