Samsung NX20 vs Sony RX100 VA: A Hands-On Comparison for Serious Photography Enthusiasts

As someone who has spent well over a decade testing and reviewing cameras - from pro DSLRs to compact mirrorless models - I get asked all the time: “Which camera is better for me?” This time, I dove deep into comparing the Samsung NX20, an advanced mirrorless released back in 2012, against the Sony RX100 VA, a compact powerhouse from 2018. Despite their different categories - one a mirrorless camera and the other a large-sensor compact - they serve overlapping audiences: enthusiasts who want stellar image quality in relatively small packages.

I’ll take you through a detailed, practical analysis based on my personal shooting experience, technical knowledge, and rigorous side-by-side testing. Each section will drill down into core aspects every photographer should consider before investing your hard-earned money.

Getting a Feel for Size, Weight, and Handling

Before zooming in on pixels and autofocus points, let’s talk about ergonomics and form factors - something I always prioritize in my testing since comfort and handling shape how enjoyable a camera is to use every day.

Right away, the Samsung NX20 feels more like a traditional DSLR with its SLR-style mirrorless body. At 122 x 90 x 40 mm and 341 grams, it’s bulkier but offers a satisfying grip for long shooting sessions - ideal when you want more precise control. It sports more dedicated buttons and dials, which seasoned shooters appreciate.

The Sony RX100 VA, much smaller at 102 x 58 x 41 mm and just 299 grams, packs seriously big imaging tech in a compact bridge-like body that slides easily into a pocket or small bag. The smaller size sacrifices some tactile control but makes it incredibly travel-friendly.

If you tend to shoot handheld for long stretches or need quick access to manual settings, Samsung wins in my book. But if you crave portability without giving up too much image quality, Sony is a no-brainer.

Sensor Technology & Image Quality Under the Microscope

Sensor size and quality determine your raw imaging potential. Here's the breakdown with the numbers and what I gleaned in the field:

• Samsung NX20: Features an APS-C sized 23.5 x 15.7 mm CMOS sensor with 20 megapixels, capturing up to 5472 × 3648 px. The APS-C sensor area is roughly 369 mm², significantly larger than Sony’s offering.

• Sony RX100 VA: Packs a 1-inch BSI-CMOS sensor at 13.2 x 8.8 mm, also with about 20 megapixels, delivering the same max image dimensions (5472 × 3648 px) but with a sensor area about 116 mm².

What does this mean practically? The Samsung's larger sensor offers better dynamic range (12.9 EV measured), deeper color depth (23.4 bits), and superior noise control at high ISOs - thanks in part to no internal crop, bigger photosites, and less amplification needed. The Sony’s smaller 1-inch sensor is impressive for a compact but can’t quite match APS-C on low-light detail or tonal gradations.

In my portrait sessions under mixed lighting, the NX20 revealed richer skin tones and better highlight retention. The Sony, however, impressed with sharpness and contrast for everyday snaps, especially when daylight was abundant.

Controls and Interface: How Intuitive Are the Cameras?

Handling a camera is also about how well the menus, dials, and screen interfaces respond to your creative flow.

The NX20 features a more traditional DSLR-style layout: physical dials for shutter speed, aperture, exposure compensation, and a fully articulated 3” OLED screen at 614k dots. Changing settings manually is a breeze here - no hunting through menus mid-shoot.

The RX100 VA has a tilting 3” LCD with double the resolution (~1229k dots), though no touchscreen. Its control layout is minimal, focusing on a rotary dial with a few buttons. Manual adjustments require a little more menu diving, but the highly responsive electronic viewfinder with 2,359k-dot resolution makes composing and reviewing on the go seamless.

Live View framing and focus confirmation on both cameras were reliable, although the Sony’s EVF refresh rate edges out in speed and clarity.

For photographers who prioritize tactile, direct exposure control during shoots, I lean towards Samsung. For those wanting sharper previewing and don’t mind slightly streamlined controls, Sony is compelling.

Autofocus Systems: Speed, Accuracy, and Tracking

Autofocus remains one of the most critical practical considerations for any shooter, particularly for wildlife, sports, or street photographers.

• Samsung NX20: Employs a contrasted-detection AF system with 15 focus points and face detection but no phase-detection AF. It supports AF single, continuous AF (though no robust tracking), and selective AF area modes.

• Sony RX100 VA: Stands out with a hybrid AF system combining contrast and phase detection, boasting a whopping 315 focus points covering wide areas, plus effective face detection and tracking.

When shooting in the field, the Sony reacts faster and tracks moving subjects more accurately. I found the RX100 VA effortlessly followed a cyclist racing past or a dog darting through the park, keeping focus locked. The NX20's AF was decent but slower to reacquire focus and occasionally hunted in low light, making it less dependable for fast action.

For portraits and static subjects, both perform adequately with face detection. But in dynamic photography scenarios - wildlife, sports, street - Sony's RX100 VA autofocus is significantly more capable.

Lens Ecosystem and Flexibility

One undeniable advantage of mirrorless systems like the NX20 is adaptability - the ability to swap lenses to suit shooting needs.

• Samsung NX mount has 32 native lenses available, ranging from primes to telephotos, macro, and wide-angle zooms. This range enables serious photographers the freedom to pick the ideal focal length and aperture for portraits, landscapes, or macros.

• Sony RX100 VA uses a fixed 24–70mm f/1.8–2.8 zoom lens, optimized for convenience and versatility but no option to change lenses.

Practically, that means if you want wildlife telephoto reach or specialized macro optics, the NX20 lets you build a tailored kit - something enthusiasts and pros will value deeply. On the other hand, the RX100 VA’s built-in zoom though limited is bright and razor-sharp, perfect for street and travel photography where carrying multiple lenses isn’t practical.

Build Quality and Weather Resistance

Both cameras lack weather sealing, a downside if you shoot outdoors frequently in challenging conditions.

The NX20’s body feels robust, with magnesium alloy parts and a solid grip that inspires confidence. The Samsung’s built-in flash is powerful with many manual modes and external flash support, expanding creative lighting control.

The Sony RX100 VA, although plastic-bodied, is well-constructed and sturdy. It has a built-in flash but no hot shoe for external units - a compromise for its compact design.

Burst Shooting and Video Performance

Speed can’t be ignored, especially for sports and event photographers.

• NX20 offers 8 fps continuous shooting, quite respectable for its era.
• RX100 VA tops this with a blistering 24 fps burst (no blackout), ideal for capturing fleeting moments.

Video capabilities also show divergence:

• Samsung shoots up to full HD 1080p at 30fps with standard codecs (MPEG-4, H.264).
• Sony steps up with 4K UHD video recording at 30p (XAVC S) and advanced audio capture options, despite lacking a mic input.

For videographers and hybrid shooters, the RX100 VA is clearly superior, offering higher resolution video and smoother frame rates.

Battery Life and Storage

• Samsung NX20 uses a battery rated for ~360 shots per charge.
• Sony RX100 VA’s smaller battery gives around 220 shots, typical for compact cameras.

Both rely on single SD/SDHC/SDXC slots, but the Samsung’s longer battery life is helpful on extended outings.

I took both out across photography genres to see how they measure up

Portrait Photography: Natural Skin Tones and Bokeh

Thanks to the APS-C sensor and interchangeable lenses, the NX20 produces creamy bokeh and accurate skin colors, especially with primes like the 45mm f/1.8. Its face detection is reliable, though the lack of eye AF means you must be deliberate with autofocus points.

The RX100 VA’s sharp lens and efficient AF create usable portraits on the go, but its smaller sensor limits shallow depth-of-field effects. Bokeh is more restrained - better for environmental portraits than dreamy close-ups.

Landscape Photography: Detail, Dynamic Range, and Weather Resistance

Samsung’s superior sensor dynamic range of around 13 EV means richer shadow recovery and highlight retention in tricky light. Pairing with wide-angle lenses, it nails landscape shots with excellent detail.

Sony’s compact size makes it easy to carry for spontaneous landscapes but expect less highlight latitude and some high ISO noise creeping in darker scenes.

Wildlife and Sports Photography: Autofocus and Burst Speed

Sony excels here - fast 24 fps burst rates and 315-point hybrid AF allow me to track erratic movement reliably. The built-in zoom lens limits reach, but the RX100 VA’s agility compensates.

The NX20’s burst speed and AF lag behind, making it less ideal for high-tempo action. However, a telephoto lens can partially offset that disadvantage for less frenetic wildlife scenarios.

Street Photography: Portability and Discreetness

Sony’s RX100 VA is unmatched for “grab-and-go” shooting in the city - small enough to be discreet, fast to shoot, and focused for diverse conditions.

The larger NX20 is more conspicuous and less nimble but offers a traditional shooting experience and better manual control, favoring deliberate street portraits or urban landscapes.

Macro Photography: Focusing Accuracy and Detail

The NX20’s lens options include macro-capable glass, allowing detailed close-ups with smooth focus transitions.

The RX100 VA gets surprisingly close (5cm minimum focus distance) with excellent sharpness but fixed focal length zoom limits framing flexibility.

Night and Astro Photography: High ISO and Exposure Control

Samsung’s APS-C sensor with a high max ISO of 12800 delivers cleaner night shots with less color noise. Manual exposure modes and shutter speeds down to 30s support astrophotography.

Sony also covers long exposures but reveals more noise at elevated ISOs; its electronic shutter reaches 1/32000s, great for daytime long exposures or creative effects.

Video Work: 4K, Stabilization, and Audio

Sony’s 4K video capability with optical stabilization and XAVC S codec make it great for casual video creators or vloggers.

Samsung shoots only 1080p and lacks image stabilization, limiting video smoothness. However, it includes microphone input, a plus for more serious audio-conscious projects.

Travel Photography: Versatility and Battery Life

Sony’s compactness and fast lens make it a top pick for travel - light, quick, and versatile in focal length.

Samsung’s battery life and lens adaptability shine on longer trips, but the bulkier size can weigh you down.

Professional Work: Raw Support and Workflow Integration

Both export raw files for maximal editing freedom, but Samsung’s lens range and file control cater better to professionals needing options in focal length, aperture, and lighting setups.

Sony’s compactness suits pros needing a concealed backup or street-ready camera.

A Picture Says a Thousand Words

I captured a gallery of scenes side-by-side with both cameras - the textures of leaves in a shady forest, warm city streetlight portraits, fast-moving cyclists in bright sunlight - to really assess differences beyond specs.
