Samsung Galaxy NX vs Sigma fp: A Hands-On Comparison for Photography Enthusiasts

Choosing a camera is about matching your shooting style, subject preferences, and budget to the tool that empowers you most effectively. In this detailed comparison, I put two distinct mirrorless cameras side by side - the Samsung Galaxy NX (2013) and the Sigma fp (2019) - to help you understand what each offers through the lens of real-world experience and technical scrutiny. Drawing on firsthand testing across multiple photography disciplines, I’ll explore every angle: sensor performance, autofocus, ergonomics, image quality, and beyond. Whether you’re a portrait shooter, landscape lover, or hybrid photo/video enthusiast, you’ll find practical insights here to guide your decision.

First Impressions: Size, Handling, and Design Philosophy

Before we dive into pixel-level detail, understanding how a camera feels in your hands sets an immediate tone for your shooting experience.

Samsung Galaxy NX is an entry-level SLR-style mirrorless camera with a chunky but solid build. Its body dimensions (137x101x26 mm) and weight (495g) show it sits in the mid-sized range for APS-C cameras, with a pronounced grip and classic DSLR ergonomics. The large 4.8” display - one of the biggest on mirrorless cameras at its time - dominates its rear.

Meanwhile, the Sigma fp is a radical counterpoint, embodying a minimalist, rangefinder-style design. Its compact 113x70x45 mm chassis weighs 422g, surprisingly light given the full-frame sensor inside. It eschews a viewfinder entirely, relying on rear screen composition or external EVFs. This stripped-down approach favors portability and modularity, appealing to hybrid shooters who prioritize video or want to build customized rigs.

If you often shoot handheld or travel light, the Sigma fp’s compact form is a delight. The Samsung Galaxy NX, larger and more conventional, feels more at home in a traditional photography kit, especially if you prize a solid grip and larger touchscreen for previewing images.

Control layouts reinforce these differences. The Galaxy NX offers a more typical DSLR-style button array and mode dial, which beginners and traditionalists will appreciate. Sigma fp’s minimalist top plate eliminates extraneous dials, relying heavily on touchscreen input and programmable buttons - great for professionals who customize workflow but can feel underwhelming for novices.

Sensor and Image Quality: The Heart of the Matter

The choice between an APS-C sensor and a full-frame sensor defines the photographic capabilities and output of both cameras.

Sigma fp features a full-frame 35.9 x 23.9 mm BSI-CMOS sensor with 25MP resolution, which delivers superior dynamic range and superior low-light performance. The sensor area is nearly 2.3 times the size of the Galaxy NX’s APS-C sensor (23.5 x 15.7 mm, 20MP), offering better noise control and shallower depth of field potential.

In my tests under controlled studio and outdoor conditions, the Sigma fp consistently outperformed in scenarios requiring high ISO sensitivity or wide dynamic range. For example, in shadow recovery or sunrise landscapes, the Sigma’s sensor retained highlight details and revealed subtle gradients with finesse.

The Galaxy NX, while capable of producing sharp, clean images in daylight or moderate ISO (up to 1600), tends to introduce noise and loses detail above ISO 3200. Its 20MP sensor resolution is respectable but noticeably behind today’s standards, especially compared to Sigma fp’s 25MP.

Both cameras include an anti-aliasing filter, which slightly softens extremely fine detail to prevent moiré but maintains overall clarity.

Practical Takeaway

• Landscape and night/astro photographers will benefit most from the Sigma fp’s full-frame sensor for its dynamic range and noise performance.
• Casual portrait and street photographers on a budget might find Galaxy NX adequate if they prioritize size and simplicity.

Autofocus Systems: Speed and Accuracy in Real Life

Autofocus (AF) performance profoundly impacts usability, especially for wildlife, sports, and candid street photography.

The Galaxy NX uses a hybrid AF system with phase detection assisted by contrast detection, but it lacks continuous autofocus and tracking capabilities. From personal experience, this means it excels in static subjects and deliberate composition but struggles to maintain focus on moving targets.

The Sigma fp relies solely on contrast detection AF but offers continuous autofocus, face detection, and advanced tracking with 49 focus points spread across the frame. During my field testing, Sigma’s AF was noticeably faster at locking focus in live view and video modes, and more reliable tracking moving subjects such as runners or pets, although slower than the latest mirrorless cameras with hybrid AF.

Important caveat: Neither camera offers animal eye autofocus nor advanced cross-point AF patterns, limiting their competitiveness in wildlife or fast sports photography where premium systems shine.

Summary of Autofocus Suitability

Displays, Viewfinders, and Interface Experience

User interface - how you review, compose, and interact with your camera - shapes your overall satisfaction and speed in shooting.

The Galaxy NX boasts a large 4.8-inch HD TFT LCD touchscreen with 922k dots. This was innovative in 2013, providing ample viewing space for composing and navigating menus. However, the screen isn’t articulating, which somewhat limits creative angles while shooting.

Sigma fp features a smaller 3.2-inch touchscreen but with a much higher resolution of 2.1 million dots, delivering a much sharper and clearer image preview despite its smaller size. This screen also supports touch focus and menu navigation, albeit within a more compact and minimalist interface.

A key distinction is that the Galaxy NX includes an electronic viewfinder - albeit modest in resolution - whereas the Sigma fp excludes any built-in EVF, pushing users to invest in optional external viewfinders for bright conditions or precise manual focusing.

Lens Ecosystem and Compatibility: Optics Matter

The lens mount greatly influences the types and styles of photography you can pursue.

• Samsung Galaxy NX: Uses Samsung NX-mount lenses, with a modest native lens lineup of about 32 lenses, mostly APS-C format primes and zooms. Samsung’s NX system never gained widespread adoption, so third-party support is limited, and many lenses are now discontinued or hard to find.

• Sigma fp: Uses the Leica L-mount, a versatile mount supported by Sigma, Panasonic, and Leica themselves. This provides access to a growing ecosystem of nearly 30 native lenses at various focal lengths and apertures, plus abundant third-party adapter options opening Canon EF, Nikon F, and others. Being full-frame native, you avoid crop factors.

This makes the Sigma fp more future-proof and flexible for photographers wanting to expand their kit with high-quality primes, fast zooms, and specialty optics.

Burst Shooting and Buffer Capacity

For sports or wildlife photographers who need speed and agility, continuous shooting specs matter.

The Sigma fp’s 12 FPS mechanical shutter speed outpaces the Galaxy NX’s 9 FPS, while the latter does not support continuous AF during bursts, hindering usefulness for dynamic subjects. The Sigma fp’s buffer performance also better sustains burst shooting, important when chasing fleeting moments.

Video Capabilities: Photo and Video Hybrid Use

Hybrid photo/video shooting continues to grow; let’s see how these two cameras stack up for videographers.

Video-wise, the Sigma fp is clearly more modern, offering native 4K UHD recording (3840x2160 @ 30fps) in a broadly accepted MOV/H.264 codec with linear PCM audio. It also supports timelapse video recording.

The Galaxy NX maxes out at Full HD 1080p, typical for cameras of its era, with a standard MPEG-4 implementation. While sufficient for casual video, serious videographers will quickly find it limiting.

Neither camera provides in-body image stabilization, so lens choice or gimbals are essential for smooth footage. Both incorporate microphone and headphone jacks, a boon for audio monitoring.

Durability and Environmental Sealing

The Sigma fp includes weather sealing to protect against dust and moisture - a valuable feature when shooting outdoors in varied conditions.

The Galaxy NX lacks any weather resistance, restricting its use in challenging environments.

For landscape photographers or those who shoot in rugged terrain, the Sigma fp is a safer bet.

Battery Life and Storage

• Galaxy NX: Rated around 440 shots per charge, powered by a proprietary battery pack. Single SD card slot (SD/SDHC/SDXC).

• Sigma fp: Battery life unspecified but uses BP-51 pack. Single SD slot supports UHS-II cards for faster write speeds, which benefits high-bitrate 4K video recording.

In my hands-on testing, the Galaxy NX’s battery often lasts a shooting day in photo mode, but continuous video or live Wi-Fi connectivity drain it quickly. The Sigma fp, while compact, requires extra batteries for full-day shoots, especially in intensive video use.
