Nikon 1 S1 vs Panasonic GX9

Comparing the Nikon 1 S1 and Panasonic Lumix DC-GX9: Two Mirrorless Cameras, Worlds Apart

Selecting the right mirrorless camera involves a careful evaluation of specifications, performance, handling, and ultimately the intended photographic use. In this detailed comparison, we examine two distinct models from very different product segments: the Nikon 1 S1, an entry-level mirrorless camera launched in 2013, and the Panasonic Lumix DC-GX9, an advanced model released in 2018. Despite sharing the rangefinder-style mirrorless form factor, these cameras exhibit markedly divergent designs, technical capabilities, and practical applications. Drawing from over 15 years of hands-on testing, and thousands of cameras evaluated, this article dissects these two products to understand which user types each best serves.

Design and Ergonomics: Compactness Versus Control

At first glance, both cameras employ a rangefinder-style body architecture, favoring a minimalist and lightweight build. The Nikon 1 S1 measures a very compact 102 x 61 x 30 mm and weighs just 197 grams, making it highly pocketable and ostensibly ideal for casual shooters and travel photographers who prioritize portability. In contrast, the Panasonic GX9, larger at 124 x 72 x 47 mm and weighing 407 grams, offers a sturdier grip and more substantial physical presence that can benefit photographers who value handling over minimalism.

Control-wise, the Nikon 1 S1 has a sparse layout, lacking illuminated buttons or advanced dials. Its fixed TFT LCD screen is limited to 460k dots resolution, without any touch functionality or articulating capability. Conversely, the GX9 boasts a higher resolution (1,240k dots) 3-inch tilting touchscreen LCD, coupled with a high-resolution electronic viewfinder (2,760k dots, 0.7x magnification) providing 100% frame coverage. Such features afford the GX9 enhanced versatility in composition and intuitive menu navigation, essentials for more deliberate photographic workflows.

While the Nikon’s simplicity reduces learning curve for beginners, its ergonomics will frustrate more demanding users seeking refined manual control. The GX9 strikes a balanced compromise, combining manageable size with a comprehensive control set sufficient for advanced amateurs and professionals in a compact system.

Sensor Technology and Image Quality: Compact Sensor vs. Balanced Resolution

A core technical dividing line between these cameras is their sensor design and resultant image quality. The Nikon 1 S1 employs a 1-inch CX-format CMOS sensor measuring 13.2 x 8.8 mm (116.16 mm² sensor area) with a modest 10MP effective resolution. The sensor incorporates an anti-aliasing filter and provides a native ISO range of 100–12,800. DXO Mark assigns the S1 an overall score of 56, with a color depth of 21.4 bits and dynamic range of 11.1 EV at base ISO. Its low-light ISO score is 397, indicating modest noise performance in challenging lighting.

In contrast, the Panasonic GX9 houses a substantially larger Four Thirds CMOS sensor measuring 17.3 x 13 mm (224.90 mm²), more than 1.9 times the surface area of the S1’s sensor. This sensor dispenses with the optical low-pass filter to maximize resolution and sharpness, outputting 20MP images at 5184 x 3888 pixels resolution. The native ISO range is 200–25,600, expandable down to 100. Although not tested by DXO Mark, the GX9 is widely recognized for superior image quality relative to 1-inch sensor cameras, thanks to its larger sensor size and higher pixel count.

This technical gulf translates to a clear practical advantage for the GX9: images exhibit finer detail, smoother gradations, and cleaner high ISO performance. Landscapes and portraits benefit markedly from enhanced dynamic range and noise control, making the GX9 more suitable for demanding photographers who require elevated image fidelity. The Nikon 1 S1, by contrast, delivers acceptable results in good lighting but struggles with noise and detail when pushed beyond ideal conditions.

Autofocus Systems: Speed versus Sophistication

The autofocus (AF) systems represent another area of divergence. The Nikon 1 S1 features a hybrid AF system combining phase-detection and contrast-detection with 135 focus points. Its autofocus is described as single-shot with tracking, but notably lacks continuous AF for video or burst shooting. The S1 uses contrast-detection, which, while accurate, tends to be slower and less reliable under low light or for tracking fast moving subjects. Face detection is not supported.

The Panasonic GX9 employs a contrast-detection DFD (Depth From Defocus) system enhanced by the Venus Engine processor, with 49 focus points. It supports rapid single, continuous, tracking, and selective AF modes, alongside superior face detection capabilities. The GX9 also supports face/eye detection, crucial for portrait and wildlife photographers to maintain focus on moving subjects’ eyes in real time. AF performance is notably snappier and more accurate, particularly in variable lighting.

For wildlife and sports photography, the Nikon 1 S1’s 15 fps burst (without continuous AF) may seem appealing on paper, but in practice, tracking moving subjects is compromised by lack of continuous focus. The GX9’s respectable 9 fps burst paired with robust continuous AF better supports action photography despite the slightly slower frame rate.

Build Quality and Weather Resistance

Neither camera offers professional-grade environmental sealing. Both omit waterproofing, dustproofing, and shock resistance features, so protection from harsh weather necessitates aftermarket solutions such as rain covers. The Nikon 1 S1’s ultra-lightweight plastic construction reinforces its entry-level positioning, and careful handling is advised to prevent damage.

The Panasonic GX9’s chassis, while still lacking weather sealing, is heavier with more metal components that provide incremental durability benefits, though it should not be mistaken for a ruggedized model. Photographers planning professional outdoor work must consider additional protective gear regardless.

Lens Ecosystem and Compatibility

Lens availability is a critical factor for system viability. The Nikon 1 S1 uses the proprietary Nikon 1 lens mount, which supports 13 lenses (as per specifications), focusing mainly on compact zooms and primes with a focal length multiplier of 2.7x due to sensor crop. The limited lens selection restricts system expandability and versatility, potentially frustrating users looking to explore diverse optics or specialized glass such as macro or ultra wide-angle lenses.

Conversely, the Panasonic GX9 utilizes the Micro Four Thirds (MFT) mount, an industry standard with over 100 native lenses from Panasonic, Olympus, and third-party manufacturers. The 2.1x crop factor allows moderate telephoto reach while maintaining manageable size. The rich MFT ecosystem affords photographers the choice of fast primes, rugged telephotos, macro lenses, tilt-shift options, and high-performing zooms. This diversity ensures the GX9 can be adapted effectively for nearly any photographic discipline.

Handling and User Interface: Screen, Viewfinder, and Controls

The Nikon 1 S1 sports a basic 3-inch fixed TFT LCD with 460k pixel resolution, offering limited brightness and no touch input. It lacks any built-in viewfinder, compelling users to rely on the rear screen for composition under all circumstances. This can prove difficult in bright sunlight or awkward angles.

In contrast, the Panasonic GX9 introduces a sophisticated 3-inch tilting touchscreen LCD with 1,240k pixels resolution, significantly enhancing visibility and operation. The tilting mechanism aids low or high-angle shooting, and the touchscreen facilitates intuitive AF point selection and menu navigation. Most importantly, the GX9 includes a built-in electronic viewfinder with 2,760k pixel resolution and full frame coverage, enabling precise composition and focus confirmation under all lighting conditions.

For photographers accustomed to mechanical rangefinders or DSLRs, the GX9’s traditional viewfinder experience provides a marked usability advantage. The Nikon’s minimalist approach might suffice for entry users but quickly feels restrictive for serious work.

Battery Life and Storage

Battery performance is moderate on both systems, with the Nikon 1 S1 rated for approximately 220 shots per charge, relying on the smaller EN-EL20 battery pack. The Panasonic GX9 offers somewhat improved endurance at 260 shots per charge, beneficial for extended photo sessions or travel where frequent recharging may be inconvenient.

Both cameras utilize single SD/SDHC/SDXC card slots with UHS-I support (GX9 only), allowing standard storage flexibility. The GX9’s support of faster UHS-I cards is advantageous for buffering large 4K video files or high-speed JPEG burst shooting.

Video Capabilities: From Junior to Advanced

Video functionality is a decisive feature differentiating the two cameras. The Nikon 1 S1 shoots Full HD (1920x1080) up to 60 fps, recorded in MPEG-4 or H.264 formats. However, it lacks a microphone or headphone jack, optical or in-body stabilization, and any 4K or high-resolution video modes. The absence of continuous autofocus during video recording further limits usability. Although this may suit casual video capture, it falls short for more ambitious or semi-professional shooting.

In contrast, the Panasonic GX9 captures UHD 4K (3840x2160) footage at 30 fps, with additional Full HD recording up to 60 fps. It incorporates 5-axis in-body image stabilization that considerably reduces camera shake during handheld video. Although the GX9 lacks microphone and headphone ports, in-body sensor stabilization partly compensates, yielding smooth and usable footage for independent filmmakers and vloggers. The inclusion of 4K Photo mode, enabling frame extraction from 4K video, adds practical versatility.

Specialized Photography Disciplines
