Samsung NX300M vs Sigma DP1s: An In-Depth Comparison for Photography Enthusiasts

Selecting the right camera is an intricate balance of understanding one’s photographic priorities, technical details, and long-term needs. Today, we juxtapose two distinct models occupying very different conceptual spaces in the camera market: the Samsung NX300M, an entry-level mirrorless system camera introduced in early 2013, and the Sigma DP1s, a large sensor compact camera from 2009 renowned for its unique sensor technology and fixed prime lens. Though both share APS-C-sized sensors - a feature typically associated with medium or high-end cameras - their design philosophies, feature sets, and user experiences diverge sharply.

Through exhaustive hands-on experience testing thousands of cameras, I will guide you through a detailed lens on their specifications, real-world usability, imaging performance, and suitability across photographic disciplines ranging from portraiture to astrophotography. I will also consider build quality, ergonomics, lens ecosystem, and video capabilities, firmly grounded in current photography standards and workflows.

Quick Size and Ergonomics Overview

When comparing cameras, physical handling and ergonomics are pivotal, especially for extended shooting sessions.

The Samsung NX300M adopts the rangefinder-style mirrorless form factor, with dimensions roughly 122 x 64 x 41 mm and weighing approximately 331 grams with battery - pleasantly compact yet comfortable for small to medium hands. The ergonomics lean towards beginners and enthusiasts who appreciate a grasp incorporating both touchscreen interaction and physical controls. Its slightly deeper grip offers tangible camera stability.

Conversely, the Sigma DP1s is a large sensor compact measuring 109 x 60 x 31 mm, weighing 270 grams. This makes the DP1s extremely pocketable yet at some cost to traditional handling comfort, given the minimalist body and the absence of a pronounced grip. Its fixed lens design means you’re carrying a highly streamlined device, ideal for stealth shooting or travel but less comfortable for prolonged handheld use.

The NX300M’s controls feel more deliberate and thoughtfully placed, while the DP1s favors minimalism, which reflects their differing user bases: the NX300M aims for versatility and user empowerment; the DP1s targets purists desiring ultimate compactness.

Design, Control Layout, and User Interface

Analyzing the top view design can reveal how intuitive and accessible the controls are under practical conditions.

The Samsung NX300M's top plate shows a traditional DSLR-ish layout: mode dial offering PASM and auto modes, dedicated shutter release, hot shoe, and a physical exposure compensation dial. This ensures quick access to frequently used settings, a welcome feature for photographers juggling manual and semi-automatic control.

The Sigma DP1s, however, lacks a mode dial. It relies on a programmatic interface to switch exposure modes, supplemented by fewer physical buttons - catering to photographers comfortable with a slower, deliberate pace of shooting.

The NX300M’s interface is enhanced by a tiltable 3.3-inch AMOLED touchscreen, with generous 768k-dot resolution, aiding in live view composition and menu navigation, although the touchscreen can feel a little oversensitive on occasion. The DP1s has a fixed 2.5-inch LCD with a much lower 230k-dot resolution, reflecting its older lineage and resulting in a less engaging visual experience when reviewing shots or navigating menus.

Refer to the back screen comparison below to better understand the impact on usability.

LCD Screen and Viewfinder Experience

The NX300M’s vibrant OLED touchscreen is a considerable advantage for users migrating from smartphone photography or those who value quick touchscreen focusing and tapping through menus. Its tilting mechanism also facilitates shooting from various angles - overhead, waist level, or low positions - enhancing versatility for street, macro, and video shooting.

Sigma DP1s has neither a touchscreen nor a viewfinder, which may challenge photographers used to eye-level framing, particularly in brighter outdoor conditions. The small, lower-res fixed screen limits detail discernment, requiring photographers to rely more on careful composition and exposure preview via histogram or highlight warnings.

Neither camera features any eye-level electronic viewfinder (EVF), a notable limitation in fast-paced or bright-light situations where an EVF assists stable compositional feedback.

Sensor Technology and Image Quality Insights

Sensor quality fundamentally impacts image resolution, dynamic range, color fidelity, and noise performance.

• Samsung NX300M:
