Here, we undertake a rigorous, experience-driven comparison between two somewhat unconventional yet technically compelling cameras from very different corners of the mirrorless spectrum: the Samsung NX300, an entry-level, widely praised compact system camera from 2013, and the Sigma sd Quattro H, a specialized advanced mirrorless camera with a unique sensor design, announced in 2016.

Both cameras target users who want serious image quality and flexibility without stepping fully into professional DSLR territory, but approach it with radically different philosophies. By exploring their sensor technologies, ergonomics, autofocus systems, and performance across various photography genres, this article aims to provide a deep, practical, and trustworthy guide to help photographers - ranging from keen amateurs to pros considering a niche tool - choose the right fit for their creative needs.

Visualizing the Cameras, Ergonomics, and Handling

Understanding a camera’s physical ergonomics, size, and control layout is crucial because these affect usability significantly, especially on long shoots or in demanding conditions.

The Samsung NX300 is a compact, lightweight rangefinder-style mirrorless camera renowned for its approachable design tailored at entry-level users stepping up from smartphones or point-and-shoot cameras. Measuring 122 x 64 x 41 mm and weighing 331 grams, it fits comfortably in one hand and offers a reasonably large grip, despite lacking weather sealing or robust protective features. Its magnesium alloy and plastic body blend durability with portability.

In stark contrast, the Sigma sd Quattro H presents a more substantial build at 147 x 95 x 91 mm (weight unspecified but noticeably heavier), designed to handle with a firm, steady grip. The larger footprint stems from the need to house a unique APS-H sized Foveon X3 sensor and to provide additional heat dissipation for its dual TRUE III processors. While lacking elaborate ergonomics targeting beginners, its button placement and chassis suggest thoughtful design for advanced shooting scenarios, particularly studio and landscape photography.

The NX300’s top plate reveals a clean, minimalistic control scheme with a mode dial, shutter button, and a few physical buttons - an intentional simplicity to ease new users into manual control. The tilting 3.3-inch Active Matrix OLED touchscreen enhances interaction, especially for autofocus selection and menu navigation.

Conversely, the Quattro H adopts a more traditional, button-heavy interface without touchscreen capabilities, reflecting Sigma’s target audience of precision-driven photographers comfortable with manual and menu-heavy operation. The inclusion of an electronic viewfinder (EVF) with 2,360K dots resolution and 0.73x magnification covering 100% frame offers an essential compositional aid absent in the NX300. For photographers reliant on critical framing and manual focus, this inclusion is a decisive advantage.

Sensor Technology and Image Quality Breakdown

Central to any camera comparison is the heart of the system: the image sensor. Here, the divergence between the NX300 and the Quattro H is profound.

The Samsung NX300 employs a conventional 20MP APS-C CMOS sensor measuring 23.5 x 15.7 mm with a typical Bayer color filter array and an anti-aliasing filter. This sensor strikes a balance that was, at the time of release, very competitive in terms of resolution and dynamic range, scoring DxOmark overall 76, with color depth at 23.6 bits, dynamic range 12.7 EV, and a low-light ISO score indicating decent high ISO performance (ISO 942 on DxO).

The Sigma sd Quattro H uses an APS-H (26.6 x 17.9 mm) Foveon X3 direct image sensor with 45 megapixels (spatial resolution 6,200 x 4,152 pixels). Unlike Bayer sensors, the Foveon X3 captures full color information at every pixel location by utilizing three stacked layers sensitive to red, green, and blue light. This results in higher perceived resolution and richer color gradation, a claim backed by many professional users favoring Sigma’s output. However, raw files are more complex to process, and high ISO performance is generally weaker due to sensor design and readout limitations, capped at ISO 6400 native.

From practical testing, the NX300’s sensor excels in versatility, offering smooth colors, robust dynamic range, and acceptable noise performance up to ISO 3200, useful in diverse lighting conditions. The Quattro H’s sensor produces images with exceptional detail and color fidelity in optimal lighting and captures subtle tonal gradations unattainable for Bayer sensors. However, in low light, noise is more pronounced, and dynamic range, while adequate, doesn’t match the best APS-C Bayer alternatives.

Autofocus Systems: Speed, Accuracy, and Practical Use

Autofocus (AF) performance can make or break the shooting experience, especially in genres where timing is critical.

The NX300 features an advanced hybrid 247-point autofocus system, mixing on-sensor phase-detection with contrast detection. This extensive AF point count and face detection facilitate precise tracking and rapid acquisition across the frame. Live-view AF and continuous AF modes are implemented effectively, achieving burst shooting at 9 fps, which at the time aligned well with many enthusiast-level mirrorless cameras.

The Quattro H employs a more modest 9-point AF system, all contrast-detection based, supplemented by phase detection, emphasizing accuracy over speed. Its AF area selection includes center-weighted and multi-area modes with face detection but without sophisticated eye or animal eye tracking. Continuous AF is supported; however, it operates at a more leisurely pace suitable for controlled shooting environments rather than fast action.

In real-world use, the NX300’s autofocus consistently outperforms the Quattro H for genres like sports, wildlife, and street photography, where speed and tracking precision are mandatory. In studio, portraiture, or architecture, the Quattro H’s AF accuracy, combined with manual focus tools, shines, albeit with a learning curve.

Handling, Screen, and Viewfinder Experience

The user interface and visual feedback components form vital touchpoints in camera-operated workflows.

The NX300’s 3.3-inch AMOLED touchscreen with 768K-dot resolution offers vibrant, high-contrast viewing with excellent outdoor visibility. Its tilting capability facilitates low and high angle shooting, a boon for macro and street photographers alike. Touch creation of focus points and intuitive swipe gestures contribute to a modern, fluid user interface.

The Quattro H features a fixed 3-inch LCD with 1.62M-dot resolution (more pixels but not touchscreen). While the display is sharp, fixed positioning can be restrictive for creative angles. Its electronic viewfinder is a highlight, offering 100% frame coverage and high resolution, enabling precise manual focus and framing in bright light conditions where LCD use is compromised.

The absence of touchscreen and reliance on smaller AF points in the Quattro H’s EVF result in a more deliberate, methodical shooting approach, preferred by studio operators and landscape photographers who benefit from slower pace and steady compositions.

Lens Ecosystem and Compatibility

A camera is only as versatile as its lenses allow.

The Samsung NX system caters to 32 native lenses, spanning wide angle, standard zooms, primes, and telephoto zooms, with a crop factor multiplier of 1.5x applying to all lenses. Although Samsung discontinued the NX line after the NX500, the existing range provides sufficient diversity for entry-level to intermediate shooters, including affordable third-party options.

Sigma’s SA mount boasts 76 lenses, including high quality primes and specialized optics explicitly designed to maximize the Foveon sensor’s characteristics. The slightly larger crop factor of 1.4x yields a slightly wider field of view compared to the NX300 for equivalent focal lengths. Sigma lenses tend to prioritize optical performance at the expense of autofocus motor speed, often requiring deliberate focusing technique.

Choosing Sigma’s SA mount for Quattro H implies an investment in a more niche lens lineup, often appealing to photographers committed to optimized image quality rather than broad system versatility.

Evaluating Battery Life and Storage Solutions

Endurance is crucial for all-day shoots or demanding itinerant work.

The Samsung NX300 uses a BP1130 battery pack rated for roughly 330 shots per charge, which is reasonable for mirrorless cameras of its generation but may necessitate spares for extended use. It accepts single SD/SDHC/SDXC cards, simplifying storage expansion.

The Sigma Quattro H employs a BP-61 battery, but exact figures on battery life are scarce, though user reports suggest moderate stamina necessitating spare batteries for extended sessions. It also supports a single SD/SDHC/SDXC card, maintaining workflow consistency.

Overall, the NX300 offers a slightly better endurance profile, fitting the expectations of outdoor and travel photographers, while the Quattro H’s power considerations require planning, befitting its more deliberate shooting style.

Connectivity and Expansion Features

Modern photography often demands wireless connectivity and flexible ports.

The NX300 includes built-in Wi-Fi with NFC support, facilitating image transfer, remote control, and instant sharing - features beneficial for social media exposure, event photography, and casual shooters prioritizing immediacy.

The Quattro H lacks any wireless connectivity, reflecting its design focus on studio and fine art photographers unlikely to require on-the-fly file sharing. It provides USB 3.0 for rapid tethered file transfers and an HDMI port but no microphone or headphone ports, and no GPS options.

For video-centric users or those needing wireless integration, the NX300 is clearly superior.

Burst Rate, Shutter Speed, and Exposure Control

Speed and exposure latitude enable photographers to capture transient moments and creative effects.

The NX300’s shutter speeds range from 30 seconds to 1/6000 sec, allowing both extended exposures and fast action snapshot capabilities. It supports various exposure modes such as aperture priority, shutter priority, manual exposure, and offers full exposure compensation and bracketing options.

Burst shooting occurs at 9 fps, competitive among entry-level mirrorless but without the buffer depth or speed of professional models.

The Quattro H offers speeds between 30 seconds and 1/4000 sec - slower at the top end, slightly limiting for ultra-fast motion freeze. Burst mode is limited to 3.8 fps, reflecting its orientation toward controlled composition rather than action capture.

Both cameras provide robust exposure mode control usable for creative experimentation; however, the NX300 excels in speed and responsiveness.
