Nikon 1 S1 vs Sony NEX-3N: A Comprehensive Comparison for Entry-Level Mirrorless Enthusiasts

Since their announcements in 2013, the Nikon 1 S1 and Sony NEX-3N have stood as prominent options for entry-level mirrorless cameras aimed at enthusiasts seeking compact, affordable systems. Both cameras boast rangefinder-style designs and straightforward controls, but beneath the surface, their technical differences result in unique strengths and limitations across photographic disciplines. Drawing from extensive hands-on testing with hundreds of mirrorless models, this analysis peels back layers of specs and field performance to guide photographers - novice or seasoned - toward an informed choice aligned with their creative goals.

Comparing Build and Ergonomics: Compactness vs. Handling

At a glance, the Nikon 1 S1 (102x61x30mm, 197g) is markedly smaller and lighter than the Sony NEX-3N, which measures 110x62x35mm and weighs 269g. The difference of roughly 70 grams and a slightly chunkier profile for the Sony translates into diverging grip ergonomics and portability.

The Nikon’s smaller size satisfies the priority of ultra-compactness and travel-friendliness  - beneficial for street photographers or those who prefer minimal kit weight. However, its reduced bulk also results in a less substantial handhold, which can affect stability with larger lenses or prolonged shooting. Additionally, Nikon’s body design lacks any provision for an electronic viewfinder (EVF), limiting framing to relying exclusively on the fixed 3-inch TFT LCD. This limitation might frustrate users accustomed to eye-level shooting in bright conditions.

Conversely, the NEX-3N’s slightly enlarged body accommodates a more comfortable grip and a 3-inch tilting LCD, increasing flexibility in composing at awkward angles. While the NEX-3N also omits a built-in viewfinder, its more robust design allows features like an external EVF (sold separately) to be attached - advantageous for landscape or sports shooters. Both do not offer environmental sealing, so caution is necessary when shooting in adverse weather.

Ergonomically, the Nikon’s control layout is more minimalistic, resulting in fewer dedicated buttons and modes directly accessible. The Sony’s interface, while still entry-level, provides a slightly more intuitive command setup that seasoned photographers will appreciate. When considering extended sessions or professional workflows, the NEX-3N’s build quality and control arrangement edge the balance in its favor.

Sensor Technology and Image Quality Performance

A fundamental distinction between these two cameras lies in their sensor design. The Nikon 1 S1 employs a 10.1-megapixel CMOS sensor measuring 13.2 x 8.8 mm (1-inch type), while the Sony NEX-3N utilizes a significantly larger 23.5 x 15.6 mm APS-C CMOS sensor with 16 megapixels.

From a technical perspective, sensor size and pixel count critically impact dynamic range, noise performance, and depth of field control. Testing via DxOMark corroborates this: the Sony’s sensor achieves markedly superior overall ratings with a DxO overall score of 74 compared to Nikon’s 56. Key image quality metrics, including color depth (Sony: 22.8 bits vs Nikon: 21.4 bits), dynamic range (12.5 EV vs 11.1 EV), and low-light ISO capability (1067 vs 397), translate into tangible gains for real-world photography.

• Low-Light and High ISO: Sony’s APS-C sensor maintains usable exposure and color fidelity at higher sensitivities, essential for indoor, night, and event shooting. Nikon’s 1-inch sensor exhibits noticeable noise past ISO 800, limiting its effectiveness in dim conditions.

• Resolution and Detail: The NEX-3N’s 16MP resolution yields larger image crops and finer detail renderings for landscape and commercial use. Nikon’s 10MP output is sufficient for casual prints and social media but can feel limiting for large enlargements.

• Depth of Field and Bokeh: Larger sensor size enables the Sony to achieve shallower depth of field and more attractive background separation, a boon for portrait and macro photography. Nikon’s smaller sensor enforces a deeper field, reducing natural bokeh quality.

In conclusion, the Sony NEX-3N sensor is substantially more capable for enthusiasts demanding higher fidelity, dynamic range, and flexibility across lighting conditions.

Display and Viewfinder: LCD Design and Usability

Both cameras dispense with electronic viewfinders, relying on rear LCDs for composition.

The Nikon 1 S1 features a fixed 3-inch TFT LCD with modest 460k-dot resolution. In contrast, the Sony NEX-3N offers a similar 3-inch, 460k-dot screen but with the added utility of tilting functionality.

Tilting screens provide critical advantages for composing low-angle macro shots, overhead street scenes, or awkward selfies (though neither model supports dedicated selfie modes). Users inclined toward experimental framing or those shooting videos manually will appreciate the Sony’s articulated display. Conversely, Nikon’s fixed LCD lacks gesture responsiveness or touch control, and the limited refresh rate can occasionally lag in live view.

Neither display incorporates touch functionality, a notable omission given the 2013 release era when other entry models began adding this feature, and may slow menu navigation and focus selection.

Autofocus Systems and Shooting Performance

Autofocus (AF) mechanisms strongly affect user experience, particularly for moving subjects and spontaneous captures.

• Nikon 1 S1 AF: The camera utilizes a hybrid AF system combining contrast-detection with limited phase-detection functionality across 135 focus points - the highest number listed among these two models. However, it relies primarily on contrast detection in live view mode with no face or eye-detection support. Continuous AF is unsupported; during burst shooting at 15fps, focus is locked on the first frame, reducing tracking accuracy for action photography. This design favors static subjects rather than dynamic shooting.

• Sony NEX-3N AF: The NEX-3N depends on pure contrast-detection autofocus with 25 focus points and selective AF area modes. Continuous AF during live view is supported, enabling better tracking of subjects in motion but at a maximum continuous shooting rate of only 4fps - significantly slower than Nikon’s burst. Notably, Sony lacks animal or eye-detection autofocus at this entry tier.

The Nikon’s higher burst rate may appeal to wildlife or sports shooters needing rapid-frame sequences, but the inability to track focus across shots undermines this advantage. Meanwhile, Sony provides a steadier AF experience for moderately moving subjects with more focus area control yet cannot match the Nikon’s speed.

In practical testing, neither model excels in fast autofocus scenarios, and users targeting high-paced action may require alternatives from newer cameras. For portraits and landscapes, both systems suffice, but with Sony delivering smoother focus transitions and fewer hunting issues in low-contrast environments.

Lens Ecosystem and Compatibility

Lens availability and quality substantially define system versatility.

• Nikon 1 System: The Nikon 1 mount supports a modest lineup of 13 native lenses designed specifically for its crop factor of 2.7x, limiting wide-angle reach and telephoto lengths. Adaptation to Nikon F-mount lenses is possible but requires an adapter with manual focus and aperture control, detracting from ease of use.

• Sony E-Mount System: Sony’s E mount supports a diverse and mature lens ecosystem, numbering over 120 lenses (including third-party options). The APS-C 1.5x crop factor retains manageable focal length equivalencies and wide-angle coverage superior to Nikon’s system. This range supports macro, telephoto, prime, and zoom varieties, satisfying photographers across genres.

From a practical standpoint, Sony’s lens catalog dramatically expands creative possibilities. While Nikon’s lenses are high quality but limited in choice and availability, Sony users enjoy ongoing investment in optics that benefit initial buyers and long-term system users alike.

Video Capabilities and Features

For those integrating video, differences narrow yet remain salient.

• Nikon 1 S1 Video: Records Full HD 1080p at up to 60fps using MPEG-4 and H.264 codecs. Also supports HFR (high frame rate) modes with low-resolution slow-motion capture (up to 1200fps at 320x120). The camera lacks microphone or headphone inputs, limiting audio control. No stabilization inside the body or lens is available. HDMI output is supported but only as basic pass-through.

• Sony NEX-3N Video: Also delivers Full HD at 1080p/60fps, using AVCHD and MPEG-4 recording formats. There are no slow-motion or high-frame-rate features, and similarly, no mic or headphone jacks for audio enhancement. No in-body stabilizer is present, but some stabilized lenses exist in Sony's lens lineup. HDMI output facilitates external monitoring.

In practical use, Nikon’s availability of ultra-high-speed capture lends it a creative niche for motion analysis, though with limited resolution trade-offs. Sony’s codec and bitrates are optimized for standard video workflows. Neither model caters well to professional video producers, but casual filmmaking is feasible.

Battery Life and Storage Flexibility

An often-overlooked practical concern is endurance.

• Nikon 1 S1: Rated for approximately 220 shots per charge with the EN-EL20 battery. Takes one SD/SDHC/SDXC card slot.

• Sony NEX-3N: Offers near double the battery life, about 480 shots on a single NPFW50 battery, enhancing the camera’s suitability for extended outings or travel. Supports both SD card formats and Memory Stick Pro Duo/Pro-HG Duo, adding versatility.

For users shooting travel or events, Sony’s longer battery life reduces the need for spares, an important operational advantage.
