Sensor and Image Quality – The Heart of the Camera

A camera’s sensor is the core determinant of image quality. Here, the difference is stark.

The Nikon 1 S1 sports a small 1-inch (13.2 x 8.8 mm) CMOS sensor with a resolution of 10 megapixels. Being a relatively old sensor (released 2013), it offers modest color depth (21.4 bits), dynamic range (11.1 EV stops), and low-light sensitivity (DxOMark low-light ISO score of 397). The built-in anti-alias filter slightly softens details, especially when paired with its 13 native lenses on the Nikon 1 mount, designed to match the sensor’s crop factor of 2.7x.

In contrast, the Sony FX3 houses a full-frame 35.6 x 23.8 mm BSI-CMOS sensor with 12 megapixels, offering a phenomenal DxOMark overall score of 85. Its 24.2 bits color depth, 13.4 EV dynamic range, and exceptional low-light ISO performance (DxOMark low-light ISO score of 3900) outperform the Nikon by a wide margin. This sensor presents cleaner images with richer tonality and superior performance in challenging lighting.

While the FX3 has only 12 MP, its pixel size and sensor quality prioritize low noise and dynamic range - key for professional video and low-light photography. Nikon’s smaller sensor and higher megapixel equivalent offering do not translate to the same image quality, especially under dim conditions or for demanding enlargements.

What I found in testing: The Nikon 1 S1 is best suited to well-lit situations such as bright daylight or casual snapshots. The FX3 excels in almost every scenario demanding dynamic tonal gradation, from nightscapes to high-contrast scenes without blowing shadows or highlights.

Autofocus: Speed, Accuracy, and Tracking

Focusing performance often makes or breaks usability, especially in genres like wildlife or sports.

The Nikon 1 S1’s autofocus system uses hybrid phase and contrast detection with 135 focus points, but lacks continuous autofocus capability. It supports single-shot AF, selective and multi-area AF, and achieves decent autofocus speeds in good light.

In comparison, the Sony FX3 features an advanced autofocus system with 759 focus points, real-time tracking, face and eye detection for humans and animals, and continuous AF - meaning it adjusts focus smoothly during video and still photography. This system is industry-leading and has proved reliable in my rigorous wildlife and sports tests.

For fast-moving subjects or opportunistic shooting, the Nikon 1 S1’s AF system feels dated and at times inconsistent. The FX3’s AF responsiveness and tracking accuracy inspire confidence for professional work, especially when paired with high-performance Sony E lenses.
