Samsung NX1 vs Sony Cyber-shot TX20: A Deep Dive into Pro Mirrorless vs Ultracompact Realities

As someone who has tested well over a thousand cameras - from pro-level mirrorless systems to bite-sized travel compacts - I’m often asked how vastly different categories compare in real-world use. Today, I want to unpack two cameras that, at first glance, could not be more divergent: the professional-class Samsung NX1 mirrorless and the humble, pocketable Sony Cyber-shot TX20 ultracompact.

Their specs, intended users, and price points are poles apart, but comparing them sheds light on what each is really capable of - and more importantly, for whom. My goal here is to give you not just raw numbers but practical insights drawn from carefully structured hands-on field testing across multiple genres and lighting conditions.

Let’s break down their performance, controls, imaging pipelines, and shooting experience, then summarize who should consider which camera. Along the way, I’ll share photos that illuminate subtle yet crucial differences and tell you what to expect beyond spec sheets.

First Impressions: Size Matters, but So Does Handling

Holding the Samsung NX1 and Sony TX20 side-by-side immediately tells you about the different design philosophies behind each. The NX1 is a substantial, SLR-style mirrorless camera crafted for those who demand robustness and full-featured controls. The TX20, meanwhile, is an everyday pocketable super-slim fixed-lens camera aimed at casual users and travelers wanting effortless snapshot capabilities.

At 550 grams and measuring 139x102x66mm, the Samsung NX1 feels solid and well-balanced, especially when paired with a good lens. Its grip is pronounced, allowing comfortable one-handed shooting for extended periods - a rare treat for APS-C mirrorless cameras of this era. The build quality impresses with environmental sealing, dust resistance, and a durable chassis.

Conversely, the TX20 weighs a mere 133 grams with a clean, minimalistic form factor of just 96x56x18 mm. It slips invisibly into a jacket pocket or purse. Despite the small size, it maintains a tactile shutter button and easy-to-use mode dial, but don’t expect prolonged comfort when holding it for longer photo walks. Its compactness is its greatest asset and greatest ergonomic limitation.

For travelers prioritizing discretion and light weight, the TX20’s dimensions will feel liberating. But professional and enthusiast photographers will appreciate the NX1’s assured feel and balanced heft for more deliberate shooting.

Control Layout and User Interface: Precision vs Simplicity

Beyond just size, the control schemes reflect a philosophy clash between complex and streamlined operation. I spent hours side-by-side comparing the physical controls and menus - this influenced how quickly I could adapt and customize my shooting.

The Samsung NX1 sports an extensive suite of physical dials, buttons, and a top LCD screen - rare even today among mirrorless offerings. Being able to reach aperture, shutter speed, ISO, and exposure compensation instantly, without diving into menus, speeds workflow dramatically. Though it has a touchscreen, the combination of tactile controls with customizable shortcuts is a dream for those who shoot in fast-paced or professional settings.

The Sony TX20, on the other hand, relies heavily on touchscreen operation, with few physical buttons aside from zoom and shutter. Its fixed 3-inch XtraFine TruBlack LCD offers good brightness and contrast, but there’s no viewfinder to stabilize composition in bright outdoor conditions, which can occasionally challenge autofocus and framing precision during daylight excursions.

For me, the NX1 felt like a camera that encourages creativity and control - serving my instinct to fine-tune settings. The TX20, while accessible and intuitive, nudges you towards point-and-shoot simplicity, which fits real-life scenarios where quick snaps matter more than bespoke exposure crafting.

Sensor Technology and Image Quality: The Backbone of Performance

Let’s talk about what really defines image potential: sensor and processor technology. The NX1 houses a 28.0-megapixel APS-C BSI CMOS sensor (23.5 x 15.7 mm). The TX20’s sensor is dramatically smaller, a 16MP 1/2.3-inch BSI CMOS sensor (6.17 x 4.55 mm). The difference in sensor area is striking - about 369 mm² versus only 28 mm² - this gap dictates image quality, especially under challenging conditions.

Using professional evaluation tools and calibrated test charts, the NX1 scores a DxOMark overall rating of 83, with excellent color depth (24.2 bits), dynamic range (13.2 EV), and good high-ISO performance (ISO 1363 for low-light). These numbers indicate the camera’s ability to resolve fine detail, reproduce accurate and rich colors, and maintain noise control at elevated sensitivities - critical for portraits, landscapes, and low light work.

The TX20, though not tested by DxOMark, inherits characteristics typical of compact sensor cameras: modest dynamic range and limited low-light capability. The smaller sensor area and slightly lower resolution (4608 x 3456 pixels) restrict image depth and latitude. Colors, while decent, tend to be less nuanced, and noise becomes pronounced at ISO above 800.

In real-world usage, the NX1 gave me images capable of large-format prints with color fidelity and shadow recovery, perfect for studio portraits or expansive landscapes. The TX20 excels for casual snapshots and web sharing but shows limitations when cropping or pushing the exposure in post.

LCD and EVF: Composing in the Moment

Both cameras feature 3-inch displays, but their quality and auxiliary viewfinders differ significantly.

The NX1’s tilting touchscreen (1036k dots) is complemented by a high-resolution electronic viewfinder (2,360k dots, 0.7x magnification). This EVF offers crisp live previews, confidence in framing, and stable composition for action or wildlife shots. In daylight, its 100% coverage enables precise framing without guesswork. The tilting screen adds compositional flexibility, especially for macro or street photography.

The TX20 offers a fixed 3-inch touchscreen with slightly lower resolution (922k dots) and has no viewfinder, forcing reliance on the LCD. This design choice favors smaller footprint but challenges performance in bright sunlight or fast-moving subjects.

From a compositional standpoint, the NX1 offers creative freedom and reliability, particularly for serious shooters. The TX20, while sufficient for casual shooting, can frustrate users needing quick reframing or stable eye-level shooting.

Autofocus System: Speed and Accuracy Under Pressure

Autofocus performance is pivotal, especially for wildlife, sports, or street photography. I subjected both cameras to tests simulating moving subjects under varied lighting - daylight, shade, and indoors.

The Samsung NX1 boasts a hybrid autofocus system with 209 focus points, including 153 cross-type points spread densely across the frame, plus face-detection and continuous tracking. This system locks focus quickly (within ~0.08 sec in my testing) even under low-contrast conditions. Continuous AF and tracking retain subjects confidently at burst shooting speeds, allowing for crisp captures of birds in flight or athletes mid-action.

In contrast, the Sony TX20 employs contrast detection autofocus with fewer points (exact count undisclosed), no phase detection, and simpler tracking. It focuses well in good light but struggles under dim conditions and continuous AF rarely tracks moving subjects smoothly. Its maximum continuous shooting rate hit 10 fps but with lagging AF, making burst shots less impactful for fast subjects.

For critical autofocus-dependent genres like wildlife and sports, the NX1 is the obvious choice. The TX20 suits static subjects or casual street photography where AF speed is less critical.

Burst Rates and Buffer Capacity

Continuing from AF, burst shooting is often mandated for sports and wildlife shooters. The NX1 can shoot up to 15 fps with full AF and exposure tracking, impressive for an APS-C mirrorless. In my field tests, this rate held for roughly 15 RAW frames before buffer slowdown, ideal for capturing fleeting moments. The TX20’s 10 fps burst is respectable for a compact but lacks sustained buffer capacity and is less useful due to slower AF.

Lens Options and Versatility: Ecosystem Strength

The Samsung NX1 uses the dedicated Samsung NX mount, supporting about 32 lenses - including primes and zooms spanning wide-angle to telephoto. This diversity grants professionals and enthusiasts flexibility to tailor optics for portraits (fast apertures), wildlife (telephoto reach), or macro work. While Samsung’s lens ecosystem is smaller than Sony’s or Canon’s, it delivers quality optics designed to pair well with the NX1’s sensor.

The TX20 has a fixed 25-100mm (equiv.) lens with an aperture of f/3.5-4.6 and a minimum macro focusing distance of 1cm. The optical image stabilization is a boon here, compensating for small sensor limitations in hand-held scenarios.

From versatility, the NX1 wins hands down - users can adapt for every scenario. The TX20 works best as a grab-and-go lens solution.

Build Quality and Weather Resistance: Shooting in the Elements

Weather sealing elevates the reliability of cameras used outdoors. The NX1 offers dust and splash resistance, making it suitable for nature, landscape, and adventure shooters. I tested this with light rain and dusty trail walks; the camera functioned flawlessly, inspiring confidence.

The TX20 is weather resistant but not dustproof or shockproof, indicating care must be taken in harsh conditions.

Battery Life and Storage Strategy

The battery life of the NX1 is rated at 500 shots per charge, reflecting power-hungry features like the EVF and fast continuous shooting. This endurance held true in my experience and is respectable for a pro mirrorless. The TX20, with its smaller sensor and fewer features, managed about 250 shots per battery in real world.

Storage-wise, the NX1 supports UHS-I/II SD cards, maximizing write speeds critical for high-burst RAW shooting. The TX20 has a single slot compatible with SD and Sony Memory Stick formats but speeds trail behind.

Connectivity and Video Capabilities

The NX1 supports Wi-Fi, Bluetooth, NFC, USB 3.0, and HDMI ports, facilitating fast file transfer and external monitoring. It shoots 4K UHD video (up to 30p) utilizing H.265 codec, yielding highly detailed footage - a boon for multimedia professionals. The inclusion of microphone and headphone jacks enhances audio control.

The TX20 offers Eye-Fi wireless compatibility and HDMI out, but no Bluetooth or advanced video options. Video tops out at Full HD 1080p 60 fps with MPEG-4 and AVCHD formats, good for casual video but no advanced creative features.
