Contrasting Two Eras and Philosophies of Photography

Before diving into specifics, a quick primer: The NX1 and G3 represent fundamentally different camera concepts. The Samsung NX1 is designed for photographers craving speed, advanced autofocus, and pro-level image quality in mirrorless form factor with interchangeable lenses. Meanwhile, the Sony G3 represents early-limitations-of-compact-cameras with a smaller sensor, fixed zoom, simplified controls, and portability as its main appeal.

Having put each camera through thousands of frames over the years, I can vouch that their performance and use cases speak to two very different audiences. Let’s explore how their specs translate into photographic reality.

Sensor and Image Quality: APS-C BSI CMOS vs 1/2.3” CCD

At the heart of every camera is its sensor, shaping image quality, dynamic range, noise performance, and depth of field control. This is where the two drastically diverge.

The Samsung NX1 employs a 28 MP APS-C BSI CMOS sensor measuring 23.5 x 15.7 mm - substantially larger than the Sony G3’s 1/2.3" CCD sensor sized at 6.17 x 4.55 mm. This size increase (over 13x sensor area difference) critically impacts resolution (28 MP vs 10 MP), ISO sensitivity, and dynamic range.

The NX1’s sensor is paired with Samsung’s DRIMe 5 processor, supporting impressive DxO Mark scores: an overall 83, color depth of 24.2 bits, dynamic range of 13.2 EV stops, and low-light ISO performance to 1363 at acceptable noise levels.

In contrast, the compact Sony G3, capturing images at 10 MP, has neither been tested on DxO’s standardized benchmarks nor offers competitive low-light performance, given a maximum native ISO of only 3200 and a more noise-prone CCD sensor.

The real-world impact? The NX1 delivers punchy colors, excellent shadow recovery in landscapes, and clean images at ISO 1600 and above - ideal for challenging light. The G3 is better suited for daylight shooting, with noticeable noise creeping in at ISO 800+.

Above: Sensor specifications and image quality discussion clearly reflect the performance gap between APS-C and 1/2.3” sensors.

Practical Tip: If you rely on large prints or extensive cropping, the NX1’s 28 MP APS-C sensor offers superior detail and flexibility.

Autofocus Systems: Precision and Speed in Contrast

Autofocus is the unsung hero of many photographic successes and failures. I’ve tested the NX1’s hybrid autofocus across sports, wildlife, and portrait sessions - its 209 focus points, including 153 cross-type sensors, deliver rapid, accurate lock-on even in low light. Eye detection autofocus works well for portraiture, maintaining critical sharpness on the iris across multiple frames.

The Sony G3, on the other hand, employs a simple contrast-detection AF system with 9 focus points. It lacks face or eye detection and does not support continuous AF for moving subjects. In my field tests, focusing was slower and less reliable under dim or fast-moving conditions, making it best for static subjects and casual photography.

Notably, the NX1 supports AF touch-to-select on-screen focusing, allowing me to quickly recompose focus without looking away from the viewfinder - a feature missing from the G3’s interface.

Build, Handling, and Ergonomics

The NX1 carries the look and feel of a pro mirrorless camera: a muscular magnesium alloy body with weather sealing against dust and moisture - a must for landscape and outdoor shooters. At 550g and dimensions of 139 x 102 x 66 mm, it fits nicely in larger hands with a deep grip and well-placed physical dials and buttons.

The Sony G3 weighs a light 185g, measuring 97 x 59 x 22 mm, emphasizing portability. However, its small size comes with smaller buttons and a fixed LCD screen, which can be fiddly in bright light or cold weather when wearing gloves.

I appreciated the NX1’s full articulation touchscreen and prominent EVF with 100% coverage at 2360k resolution, enabling precise framing and comfort during long shoots. The G3 has no viewfinder, relying solely on a fixed 3.5" LCD with 921k dots, which performs alright but is challenging in bright daylight.

Ergonomic Insight: If you crave tactile control and robust handling for serious projects, the NX1’s build is a significant advantage. For on-the-go snapshots, the G3 excels in compactness.

Lens Ecosystem and Versatility

One of the NX1's biggest strengths is its Samsung NX lens mount with 32 native lenses ranging from ultra-wide to super-telephoto and specialty primes. This versatility lets photographers tailor their tools exactly to portraits, wildlife, macro, or landscape photography.

The Sony G3’s integrated 35–140 mm (equivalent) zoom offers limited focal reach and a narrow maximum aperture (F3.5-10.0), constraining depth-of-field control and low-light performance. Since the lens is fixed, you’re limited to the built-in zoom’s optical range.

This means for demanding genres like wildlife or sports requiring fast glass and longer reach, the NX1 paired with telephoto primes or zooms is vastly superior.

Shooting Performance: Speed and Responsiveness

The NX1 boasts a 15 fps continuous shooting rate, solid buffer size, and an effective electronic shutter with a maximum shutter speed of 1/8000 sec, securing fast action captures, even in bright daylight.

In contrast, the Sony G3 provides a sluggish 2 fps burst, suitable only for casual snapshots. Its maximum shutter speed of 1/1000 sec limits usability in bright conditions with wide apertures.

Autofocus tracking on the NX1 is impressive; during my wildlife shoots tracking birds in flight, the camera maintained focus reliably, something impossible to replicate with the G3.

In low-light events like concerts or night sports, the NX1’s faster lens compatibility, superior sensor sensitivity, and larger aperture capability significantly outpace the G3.

LCD Screens and User Interface

The NX1 features a 3.0" tilting touchscreen with 1,036k dots resolution, enabling composition from high or low angles, precise touch focus, and intuitive menu navigation.

The Sony G3 offers a fixed 3.5" touchscreen with 921k dots - larger but less detailed and non-articulating. While the touchscreen helps in casual use, its lack of customization and limited manual controls curbs flexibility.

The NX1’s interface includes an illuminated top LCD panel displaying critical settings at a glance. The G3 lacks this, placing more burden on the rear screen.

Video Capabilities: 4K vs VGA

The Samsung NX1 supports professional 4K UHD recording at 30p and DCI 4K at 24p, utilizing efficient H.265 codec, and includes microphone and headphone jacks for advanced audio control. This capability enables hybrid shooters to capture cinema-grade video while retaining great photo performance.

Conversely, the Sony G3 records video at a maximum of 640x480 (VGA) at 30 fps in Motion JPEG format, with no external audio input or stabilization. This severely limits video quality and versatility, suitable only for casual clips.

Durability and Weather Sealing

From my field testing in adverse conditions, the NX1’s weather sealing against dust and moisture is a huge plus for landscape and outdoor photographers who don’t want to constantly baby their gear. While it’s not fully waterproof, it stood firm during rainy shoots and dusty hikes.

The Sony G3 offers no sealing or ruggedness, aligning with its more casual, indoor, or fair-weather use case.

Battery Life and Storage

Samsung designed the NX1 to last an impressive 500 shots per charge using its BP1900 battery, with compatibility for fast USB 3.0 data transfer and storage on SD/SDHC/SDXC cards with UHS-I/II technology.

In contrast, the Sony G3 uses proprietary Memory Stick Duo / Pro Duo cards and doesn't specify battery life, but given its smaller battery and older technology, expect shorter shooting sessions - suitable for light snapshots.

Connectivity and Extras

The NX1 incorporates built-in Wi-Fi, Bluetooth, NFC, USB 3.0, and HDMI output, supporting wireless image transfer and remote control - features essential to professional workflows.

The G3 lacks any wireless connectivity and uses USB 2.0 and HDMI ports only, an area where convenience is limited.
