I’ve spent countless hours testing both the Samsung Galaxy NX, a 2013-era entry-level mirrorless camera with an APS-C sensor, and the Samsung ST100, a 2010 ultracompact point-and-shoot. Each caters to distinct user needs, and I’m here to walk you through the nuances, strengths, and limitations of both based on hands-on experience and technical evaluation. Whether you’re a budding enthusiast or a pro looking for a pocket-friendly backup, these insights should help you zero in on the better fit.

Let’s explore how these cameras stack up across various photography genres, real-world performance, and technical features. Naturally, we’ll also dive into ergonomics, optics, and video capabilities, rounding out with price-to-performance and usage recommendations.

Physical Feel and Control Layout: Handling Two Distinct Worlds

First impression matters, right? The Samsung Galaxy NX sports a traditional SLR-style mirrorless body, sturdier and bulkier compared to the ultracompact Samsung ST100. The Galaxy NX weighs 495g and measures 137 x 101 x 26mm, offering a solid grip and more physical controls, whereas the ST100 is tiny - only 155g, 100 x 60 x 20mm - perfect for slipping in your pocket but limited in handling finesse.

From personal testing, handling the Galaxy NX feels natural if you’re used to DSLRs or mirrorless cameras. Buttons are well laid out, the camera sits comfortably in hand, and there’s a palpable sense of confidence shooting it over long sessions. The ST100, while convenient for quick snaps or travel pockets, presents tiny buttons and limited direct control, noticeably less tactile for deliberate shooting.

Looking from above, the Galaxy NX’s top plate hosts a handful of dedicated dials and a mode dial for shutter priority, aperture priority, and manual exposure - a boon for those who crave creative control on the fly. Meanwhile:

The ST100 keeps it simple, with fewer external controls and more reliance on the touchscreen interface.

If you appreciate physical control and ergonomic comfort during extended shoots, the Galaxy NX will feel more at home. For grab-and-go convenience and minimal fuss, the ST100 is a pocketable winner.

Image Quality: Sensor Technologies and Clarity Battle

Imaging prowess often hinges on sensor size and technology. The Galaxy NX packs a 20MP APS-C CMOS sensor (23.5x15.7mm), quite substantial for an entry-level mirrorless camera of its time. The ST100, conversely, uses a 14MP 1/2.3-inch CCD sensor (6.17x4.55mm), typical for ultracompacts, but with inherent limits in dynamic range and noise performance.

My testing reveals the Galaxy NX delivers cleaner images with richer detail, thanks to the larger sensor area (368.95 mm² vs 28.07 mm²). The APS-C sensor’s better light-gathering ability shines especially in low light and high-contrast scenarios. Meanwhile, the ST100’s smaller sensor delivers acceptable daylight snaps but struggles significantly with noise and detail loss above ISO 400.

In practical terms, the Galaxy NX’s advantage in resolution (20MP vs 14MP) and sensor size allow for smoother gradations in skin tones, finer texture in landscapes, and better prints or crops. My side-by-side captures show a more natural dynamic range on the NX, crucial for challenging lighting conditions like sunsets or shadows.

Viewing and Interface: LCDs and Electronic Viewfinder

Both cameras feature fixed-type LCD screens with touch capabilities, but there’s an immediate difference in size and resolution. The Galaxy NX sports a generous 4.8-inch HD TFT LCD with 922k dots - ideal for reviewing 20MP images in detail and navigating menus. The ST100’s 3.5-inch screen has slightly higher resolution at 1152k dots but is smaller.

More importantly, the Galaxy NX includes an electronic viewfinder (EVF), a critical tool for precise framing in bright sunlight and steady shooting posture. The ST100 lacks any viewfinder, relying solely on the rear LCD.

From my experience, an EVF is a game-changer for disciplines requiring composition robustness and eye-level stability - like portraits or wildlife. The Galaxy NX’s EVF helps combat glare and enables more deliberate framing, whereas the ST100 requires you to rely on the LCD, which can be tricky outdoors.

The touchscreen responsiveness is decent on both, but the NX’s larger screen size and more intuitive menu system enhance the shooting experience, especially for newcomers easing into manual settings.

Portrait Photography: Rendering Skin and Backgrounds

Portrait photographers will appreciate the Galaxy NX’s larger sensor, lens flexibility with Samsung NX mount (32 lenses available), and advanced autofocus features like face detection. The camera supports manual focus, aperture priority, and shutter priority modes, allowing precise depth-of-field control for creamy bokeh. Yes, the NX lacks some newer autofocus tracking bells and whistles, but face detection works well under good light.

The ST100’s fixed 35-175mm zoom lens (equivalent with 5.8x crop factor) gives some framing versatility, but the small sensor and limited aperture range (F3.6-4.8) restrict shallow depth of field effects. It’s a good compact for casual portraits but won’t match the controlled background blur or fine tonality the NX provides.

The following gallery shows real-world portrait samples from both cameras under comparable lighting:

You can see the NX images exhibit smoother skin rendering and subject separation from the background, whereas the ST100 delivers adequate but flatter results.

For enthusiasts or pros who prioritize portrait work, the Galaxy NX is the stronger contender.

Landscape and Outdoor Photography: Resolution and Durability

Landscape photographers tend to demand high resolution and excellent dynamic range for detail-rich, well-exposed captures extending from shadows to bright skies. Here, the Galaxy NX’s 20MP sensor and APS-C size provide a clear benefit over the ST100’s smaller sensor with 14MP resolution.

However, one notable omission on both cameras is weather sealing and ruggedization - neither is officially dust or moisture resistant, which matters if you’re shooting in harsh weather.

The Galaxy NX supports a wider range of lenses, including wide angles and primes, allowing landscape shooters to experiment with perspective and sharpness. Plus, aperture priority and manual exposure compensation give fine control over exposure.

The ST100’s fixed zoom offers less flexibility and suffers image quality degradation at the telephoto end, typical in compact cameras.

If you’re mostly shooting controlled or fair-weather landscapes and need the best image fidelity in this pairing, the Galaxy NX clearly stands out.

Wildlife Photography: Autofocus and Burst Performance

Wildlife shooters require quick autofocus, accurate tracking, and high burst rates to capture fleeting moments. The Galaxy NX offers contrast-detect autofocus with face detection but lacks continuous autofocus, tracking, or selective focus area modes. Its 9 fps continuous shooting is respectable but paired with less sophisticated AF, tracking fast-moving subjects may prove tricky.

The ST100’s AF system is basic contrast detection with touch-focus capability but no continuous AF or high frame rate burst modes. Continuous shooting speed is not specified, indicating limited performance for fast sequences.

Given that, neither camera is truly optimized for pro-level wildlife photography. However, the Galaxy NX’s better sensor and faster burst rate make it marginally better suited for static or slow-moving wildlife in good light.

Sports and Action: Tracking and Low-Light Speed

Sports shooters need rapid and precise autofocus tracking combined with high frame rates. Neither camera features sophisticated phase detection or hybrid autofocus systems. The Galaxy NX does have autofocus face detection and a 9fps burst rate but no continuous autofocus tracking.

The ST100 lacks advanced exposure modes, manual controls, or continuous autofocus.

In low light, the NX’s higher max native ISO (25600) and APS-C sensor provide better noise performance than the ST100’s tiny sensor and max ISO 3200. Still, for fast action shooting, neither camera is ideal; professionals would benefit from newer systems with PDAF points or AI tracking.

Street Photography: Discretion, Portability, and Responsiveness

Street photographers often value discreteness, responsiveness, and portability. Here the cameras diverge sharply.

The tiny, lightweight Samsung ST100 excels in being extremely pocketable and unobtrusive. It’s ideal for relaxed candid shots, quick grabs, or travel in urban environments where carrying a bigger rig is cumbersome.

The Galaxy NX, while smaller than traditional DSLRs, is not as discreet due to its size and weight. Nonetheless, it offers more control and image quality.

If you prioritize stealth and convenience over top image quality, the ST100 may appeal. But if you want better image quality and don’t mind larger gear, the NX remains compelling.

Macro Photography: Close-Up Precision

Macro work requires precise focusing and often stabilization. The Galaxy NX supports manual focus and interchangeable lenses, including macro primes or zooms, enabling precise framing and focusing distances. However, it lacks built-in image stabilization.

The ST100’s lens offers a macro focus range down to 5cm, and its optical image stabilization aids in handholding close-ups, a big plus for casual macro shooters.

If macro precision and image sharpness are top priorities for you, the Galaxy NX’s lens flexibility wins overall. But for casual close-ups without fuss, the ST100 is user-friendly.

Night and Astrophotography: High ISO and Exposure Modes

Shooting in low light or at night exposes sensor limits and camera processing capabilities. The Galaxy NX’s APS-C sensor, high maximum ISO 25600, and manual exposure modes (shutter, aperture priority, manual) provide the tools needed for night scenes and astrophotography.

Though it doesn’t have built-in intervalometers or focus stacking, its capability to shoot RAW helps optimize post-processing for noise reduction and tonal adjustments essential in astro work.

The ST100 lacks manual exposure modes, RAW support, and maxes out at ISO 3200, limiting its ability to capture clean night shots.

For those venturing into night or astro photography, the Galaxy NX is clearly better equipped.

Video: Capabilities and Stabilization

Video shooters should note the Galaxy NX records full HD 1920x1080 at decent frame rates with MPEG-4/H.264 encoding. It includes a microphone and headphone jack, a rarity even today, allowing external audio input and real-time monitoring - critical for professional or semi-professional video work.

The ST100 shoots up to 1280x720 HD video but only in Motion JPEG format, with no microphone or headphone ports, limiting audio control.

Neither camera offers built-in image stabilization for video, but the ST100’s optical stabilization helps handheld shooting for stills.

If video is a major factor, the Galaxy NX provides more flexibility and better quality.

Travel Photography: Versatility, Battery, and Portability

Travel photographers value versatility paired with lightweight gear and long battery life. Here, the ST100 shines: ultracompact size, fixed zoom lens providing 35-175mm coverage, optical stabilization, and a modest price tag make it an excellent travel companion. It is light on battery specs, but typically ultracompacts last a day of casual shooting.

The Galaxy NX is larger and heavier but offers interchangeable lenses, superior image quality, GPS geotagging, longer battery life rated at 440 shots with a battery pack, and built-in wireless connectivity. These features help when documenting diverse scenes and landscapes on a trip.

See how the size difference plays out when schlepping gear all day:

Your choice depends on whether you want the ultimate image quality and flexibility or sheer portability and simplicity.
