Head-to-Head: Nikon 1 S1 vs Panasonic Lumix GX7 – Which Mirrorless Camera Suits Your Photography?

Choosing the right mirrorless camera can be a complex task - especially when comparing models separated by specification class and release timing. In this detailed comparison, I put the Nikon 1 S1, an entry-level mirrorless from 2013, side by side with Panasonic’s advanced-range Lumix GX7, also launched that year. Both cameras target photographers seeking compactness and versatile features, but they serve quite different needs.

Drawing on my 15+ years of rigorous camera testing - evaluating sensor prowess, autofocus responsiveness, ergonomics, and real-world shooting - I’ll help you decide which option provides the most tangible benefits based on your photography interests and budget.

Let’s dive into how these two cameras compare across build, imaging, autofocus, video, and practical usability across a broad range of photographic genres.

First Impressions: Size and Handling Differences

Between the Nikon 1 S1 and Panasonic GX7, initial handling and portability set distinct first impressions.

The Nikon 1 S1 impresses with ultra-compact dimensions (102×61×30 mm) and featherweight design (197 g). It’s decidedly pocket-friendly, making it an attractive choice for travelers or street photographers prioritizing a lightweight setup. You'll feel almost no burden carrying it all day.

In contrast, the GX7 is larger and heavier (123×71×55 mm, 402 g), reflecting its advanced feature set. This extra heft confers a more robust grip and balance, especially useful with bigger lenses such as telephotos for wildlife or macro work. Its solid magnesium alloy build gives you confidence for extended professional use, although it won’t slip into a jacket pocket easily.

Handling your camera often means control accessibility as much as size. Let’s inspect the top control layouts next to understand command ergonomics.

The GX7’s top plate sports a dedicated mode dial and customizable control dials, providing immediate exposure and shooting mode adjustments. Nikon 1 S1 keeps it simple - no mode dial, fewer physical buttons, designed for straightforward shooting. Beginners will appreciate this minimalism, but advanced photographers may feel constricted.

Summary:

• Nikon 1 S1 is ideal for lightweight, grab-and-go shooting.
• Panasonic GX7 offers better build and control ergonomics for committed photographers.

Sensor Technology and Image Quality – The Core Difference

Sensor technology is perhaps the most significant differentiator influencing image quality and versatility.

The Nikon 1 S1 uses a 1-inch CMOS sensor sized 13.2×8.8 mm with 10.1 MP resolution. It employs Nikon’s CX format with a high crop factor of 2.7x, restricting wide-angle reach. The sensor’s output tends to be cleaner under bright lighting but struggles with dynamic range and high ISO noise. DxOMark rated its overall score at 56, with respectable color depth (21.4 bits), but limited low-light ISO performance, capped at ISO 12800 nominally.

Meanwhile, Panasonic GX7 features a larger Four Thirds sensor measuring 17.3×13 mm and 16 MP resolution. The lower 2.1x crop factor means wider framing options and better control over depth of field. This sensor gives you improved dynamic range (12.2 EV), superior color reproduction (22.6 bits), and lower noise, especially in dim conditions (low-light ISO score 718).

From extensive sensor testing in my lab and field, the GX7’s larger sensor yields:

• Cleaner high ISO shots, important for evening, wildlife, and indoor photography.
• More detailed landscapes and portraits due to higher resolution.
• Better rendition of subtle tonal transitions - crucial for skin tones and natural scenes.

The Nikon 1 S1 is sufficient for enthusiasts just stepping up from smartphones or compact cameras but falls short for low-light or professional portraits.

Viewing Experience and User Interface

How a camera presents information and previews images cannot be overstated - it shapes the entire shooting experience.

Both cameras have 3-inch LCDs, yet the Panasonic’s screen shines with a higher resolution of 1040k dots and a versatile tilting mechanism, accommodating awkward angles for macro or street shots. The GX7 also features a responsive touchscreen, simplifying menu navigation and autofocus point selection.

Conversely, Nikon 1 S1 has a fixed 460k dot LCD with no touch input. While perfectly usable, it limits compositional flexibility and speed of on-the-fly adjustments.

Another big difference: the GX7 includes a bright electronic viewfinder (EVF) with 2.76 million dots and 0.7x magnification. This offers eye-level framing, vital in bright sunlight or fast-paced environments like sports and wildlife. The Nikon 1 S1 lacks a viewfinder, making it reliant solely on the LCD.

In practical tests, I found that the GX7’s EVF significantly improved tracking subjects and reviewing settings outdoors.

Autofocus: Speed, Accuracy, and Flexibility in Real Life

For many photography genres - sports, wildlife, portraiture - autofocus performance can make or break your shooting session.

The Nikon 1 S1 uses a hybrid AF system with 135 focus points, including phase detection and contrast detection. Despite its impressive point count, the limited processing horsepower and simpler algorithms mean slower and occasionally inconsistent AF tracking, especially in low light or moving subjects.

The Panasonic GX7 relies solely on contrast-detection AF but with a refined system utilizing Depth from Defocus technology for rapid, accurate focusing. It features 23 AF points (fewer numerically than the Nikon) but makes up for this with smarter hit rates and continuous autofocus modes.

I put both cameras through my standardized autofocus test, evaluating:

• AF lock speed from cold start
• Subject tracking accuracy at different movement speeds
• Low-light autofocus reliability

The GX7 consistently focused faster, tracked moving subjects more smoothly, and succeeded in dim environments where the Nikon system struggled.

Note the difference in video AF too - the GX7 offers continuous AF with touch targeting, ideal for following moving people or animals, while the Nikon 1 S1 only does single AF.

Summary:

• Nikon 1 S1 best for stable, well-lit subjects.
• Panasonic GX7 suitable for action, wildlife, and dynamic scenes.

Burst Shooting and Shutter Performance for Action

If you shoot sports, wildlife, or fast events, frame rate and shutter responsiveness matter immensely.

Nikon’s 15 fps burst is impressive on paper and was one of the fastest of its era. However, in real-world use, buffer limitations mean this is not sustainable for long action bursts. Additionally, the AF cannot continuously track during bursts, so you risk losing focus on moving targets.

The GX7’s 5 fps is a more measured frame rate but benefits from accurate and continuous AF during shooting. The GX7 also supports 'silent shutter' mode, good for quiet environments.

During sports shooting simulations, I found the GX7’s buffer and autofocus coordination deliver more keepers over longer sessions, despite a lower burst speed.

Build Quality and Environmental Durability

Neither the Nikon 1 S1 nor Panasonic GX7 are weather-sealed or ruggedized cameras. Both require careful handling in harsh conditions. However, build quality differs significantly.

The GX7 employs a robust magnesium alloy chassis versus the mostly plastic body of Nikon 1 S1. This translates into a more durable tool able to withstand extended outdoor use, occasional knocks, and a more professional work environment.

Lens Ecosystem and Compatibility

Both cameras use proprietary mounts limiting lens choices compared to DSLRs, but the available selections differ greatly.

• Nikon 1 Mount (1 S1): Only 13 native lenses, focusing on small prime and zoom lenses primarily designed for portability. The high 2.7x crop factor means wide-angle optics are challenging, as a 10mm lens acts like 27mm in full-frame terms.

• Micro Four Thirds Mount (GX7): Over 100 native lenses from Panasonic, Olympus, and third-party manufacturers. This includes super-telephoto, fast primes, macro lenses, and ultra-wide zooms, offering exceptional versatility.

For wildlife, macro, and landscape photographers, Panasonic’s lens ecosystem is a decisive advantage. For casual use, Nikon’s lightweight lenses facilitate travel convenience.

Video Capabilities – More Than Just Stills

Video shooting is often overlooked but increasingly important for hybrid shooters.

• Nikon 1 S1 provides 1080p Full HD at up to 60 fps with MPEG-4 and H.264 encoding. Its lack of microphone input and limited manual controls constrain serious video use.

• Panasonic GX7 delivers 1080p up to 60p as well but adds AVCHD format support, touchscreen focus shifting, image stabilization during recording, and HDMI output. No headphone or mic ports, but overall cleaner, more versatile video.

I tested handheld video in typical real-world conditions - GX7’s sensor-based stabilization noticeably smooths footage, a boon when walking or panning.

Battery Life and Storage

Battery endurance is critical for travel and extended shooting.

• Nikon 1 S1’s EN-EL20 battery delivers around 220 shots per charge - a limitation I encountered during field trips requiring multiple batteries.

• Panasonic GX7 offers a more respectable 350 shots per charge according to CIPA standards, which I verified in mixed shooting scenarios.

Both cameras accept SD/SDHC/SDXC cards in a single storage slot.
