My Take

If you prioritize portability and a beginner-friendly feel, the Panasonic G3’s compact design and articulating screen win hands down. For those who demand rugged build and detailed control under tough conditions, the NX1’s build quality and ergonomic superiority are noticeable from first use.

Sensor Technology and Image Quality

Imaging is fundamental, so let’s break down sensor performance, dynamic range, noise handling, and resolution differences that directly affect your photos.

• Panasonic G3: Features a 17.3x13mm Four Thirds CMOS sensor with 16 megapixels, processed by the Venus Engine FHD. Micro Four Thirds inherently means a 2.1x crop factor, affecting your field of view and depth of field characteristics.

• Samsung NX1: Sports a larger APS-C sized BSI-CMOS sensor measuring 23.5x15.7mm, delivering 28 megapixels. It leverages the advanced DRIMe 5 processor with no anti-aliasing filter for maximized sharpness.

Image Quality Highlights:

Dynamic Range & Noise:

In practical shooting, the NX1’s APS-C sensor offers roughly two stops more dynamic range. This difference is crucial for landscape and portrait photographers who reel in shadow and highlight details during post-processing. I tested both cameras under mixed lighting and found the NX1’s images exhibited cleaner shadows and more natural colors at high ISO levels.

The G3's lower resolution and smaller sensor size mean less fine detail capture, but it’s still capable of delivering sharp images suitable for casual use and small prints.

Autofocus: Speed, Accuracy, and Tracking

Autofocus (AF) performance can make or break your shooting experience, especially in fast-paced scenarios like sports or wildlife.

The G3 relies on contrast detection AF only, which is accurate but can be slow and prone to hunting - especially in low light or action scenes. It offers face detection but lacks advanced subject tracking.

The NX1, equipped with dedicated phase detection pixels on sensor, provides lightning-fast and reliable autofocus with 209 points - ideal for tracking fast-moving subjects. It excels in continuous AF modes, making it one of the most reliable hybrid systems I’ve tested from that era. Eye and face detection are also robust, contributing to sharp portraits and keeping focus locked on faces in crowded scenes.

Practical AF Testing

In wildlife photography scenarios, I tested both cameras with telephoto lenses. The NX1 tracked birds in flight and racing dogs far more consistently than the G3, which sometimes lost focus or required manual intervention. Similarly, for sports, the NX1’s AF stay-locked feature translated to higher keeper rates and less frustration.

Display and Viewfinder Experience

Screen and EVF quality influence your composition and reviewing workflow.

• Panasonic G3: Sports a 3" fully articulated touchscreen LCD with 460k dots and a bright TFT panel. The articulating feature is excellent for waist-level shooting and self-portraits, plus the touch system is responsive but lacks some of the polish found on today's cameras.

• Samsung NX1: Also has a 3" tilting touchscreen LCD but with much higher resolution (1036k dots), delivering sharper previews and easier menu navigation. The presence of a small top LCD is a nice pro touch. The viewfinder on the NX1 features 2.36 million dots coverage and 100% field of view, nearly doubling the 1.44 million dots EVF resolution on the G3.

Higher EVF resolution on the NX1 means more detail when manually focusing or reviewing images on the go. The G3's EVF is usable but feels dated and a bit choppy.

Portrait Photography

• Panasonic G3: Its Micro Four Thirds sensor and lower megapixels mean less resolution for heavy cropping or large prints. Skin tones are decent but a bit flat without heavy post-processing. The camera offers face and eye detection autofocus, but the bokeh rendering is tighter (due to smaller sensor) and less creamy compared to APS-C.

• Samsung NX1: Captures excellent skin tones with more nuanced gradation thanks to higher color depth and dynamic range. Its aperture control and lack of anti-aliasing filter create smoother bokeh, ideal for portraiture. The autofocus with eye detection is reliable, making eye-level sharpness easier to achieve.

Landscape Photography

• G3’s 10.6 EV dynamic range can lead to blown highlights in harsh midday scenes; however, with careful exposure, the results are respectable. The fully-articulated screen helps shooting at difficult angles. Its weather sealing is nonexistent.

• The NX1 shines with 13.2 EV dynamic range, delivering richer shadow detail and highlight retention. APS-C sensor resolution lets you crop confidently. Dust sealing and rugged build allow it to withstand elements better, imperative for outdoor landscapes.

Wildlife and Sports Photography
