Having spent many hours testing and dissecting both cameras, I’m eager to guide you through their strengths, weaknesses, and real-world usability across a variety of photography disciplines.

Whether you’re a photography enthusiast deciding between proven DSLR ergonomics or cutting-edge mirrorless innovation, or a professional hunting for the best value, this detailed comparison will help clarify which camera suits your needs and creative ambitions.

First Impressions: Size and Handling in Your Hands

The tangible feel of a camera - the way it fits in your hand, the weight balance, and the placement of controls - is an irreplaceable part of the shooting experience. Having used hundreds of cameras across categories, I always start my evaluation with physical ergonomics.

Samsung GX-20: Classic DSLR Bulk with Purpose

At 800 grams and measuring 142 x 101 x 72 mm, the GX-20 embodies the traditional DSLR heft. This “mid-size SLR” design offers solidity and durability - it feels reassuring under the palm, particularly when paired with larger lenses. Pentax KAF2 lens mount compatibility also means access to a well-established lens ecosystem.

Samsung NX300: Compact, Light, and Agile

Weighing just 331 grams and sized at 122 x 64 x 41 mm, the NX300 is strikingly more compact. It fits easily into one hand or modest camera bags, suiting travel and street photography idea(l)s like a glove. The rangefinder-style mirrorless construction means fewer mechanical parts, enhancing portability.

Looking at the top deck controls in detail, the GX-20 sports a more traditional DSLR layout with dials for shutter speed, exposure modes, and customizable buttons for rapid adjustments. The NX300, with its sleek rangefinder silhouette, has a cleaner top plate but relies more heavily on screen operation and fewer physical dials.

My takeaway: If you prefer tactile feedback, physical dials, and the reassuring heft of a DSLR, the GX-20 excels in extended shoots. Conversely, the NX300’s minimalist, light design favors spontaneity, particularly in travel or street contexts.

Sensor and Image Quality: The Core of Photographic Output

The sensor’s capabilities define the creative and technical possibilities of a camera. Both these models use APS-C CMOS sensors, but their characteristics and processing differ markedly.

Sensor Specifications and Raw Performance

• GX-20: 15 MP APS-C sensor (23.4 x 15.6 mm), 1.5x crop factor, with a fairly standard anti-aliasing filter.
• NX300: 20 MP APS-C sensor (23.5 x 15.7 mm), similar crop factor, but a newer generation sensor chipset (Samsung DRIMe IV processor) and an OLED screen.

Color Depth and Dynamic Range

According to DXOMark benchmarks, the NX300's sensor outperforms the GX-20, notably in dynamic range (12.7 EV vs 11.2 EV) and low-light ISO performance (942 vs 714). This means the NX300 can recover more shadow details and produce cleaner images at higher ISO settings - an important factor for event, sports, and night photography.

Color depth edges slightly toward the NX300 too (23.6 bits vs 23.1 bits), suggesting richer color rendition, especially in nuanced tones like skin - crucial for portraiture.

Real-World Image Quality and Output

I performed side-by-side tests shooting RAW files under controlled conditions. The NX300 consistently delivers cleaner, sharper images with less noise from ISO 800 upwards. The higher resolution sensor allows for larger prints and cropping flexibility. The GX-20, however, holds its own in well-lit scenes, with classic color rendering and pleasing texture gradations despite the fewer megapixels.

Anti-Aliasing and Detail

Both cameras feature an anti-aliasing filter, which reduces moiré but slightly softens fine details. For landscape and macro shooters craving razor-sharp files, this might be limiting - but it’s a common trade-off in consumer-level APS-C models.

Focusing Systems and Burst Rate: When Speed Matters

Whether capturing a fleeting expression, a bird mid-flight, or athletes dashing on the field, autofocus (AF) system performance and continuous shooting speed are deciding factors.

Autofocus Capabilities at a Glance

Samsung’s mirrorless NX300 leverages a large number of focus points and hybrid AF technology - combining phase and contrast detection for speed and accuracy. Importantly, it supports face detection autofocus, invaluable for portraits and events.
