Panasonic GX7 vs Panasonic S2: A Detailed Comparison to Guide Your Next Camera Choice

Choosing the right camera can be a daunting task - especially when faced with models from the same brand that serve drastically different photography needs. Today, I'm diving deep into two Panasonic cameras: the advanced mirrorless Lumix DMC-GX7, announced in late 2013, and the compact point-and-shoot Lumix DMC-S2, which came out in early 2012. Both come from a respected maker renowned for reliable imaging gear, but they target fairly different users.

Having tested and used hundreds of mirrorless, compact, and DSLR cameras over the past 15 years, I’ll offer you an in-depth, hands-on comparison. You’ll find this helpful whether you’re a seasoned enthusiast, a beginner stepping into serious photography, or someone balancing budget with capability.

First Impressions: Design, Handling, and Physical Presence

At first glance, these two Panasonic cameras couldn't be more different in size and style.

The GX7 is a rangefinder-style mirrorless camera with a robust metal body that feels reassuringly solid in hand. Measuring 123x71x55mm and weighing 402 grams, it strikes a balance between compactness and ergonomics. Its thoughtfully laid-out controls and comfortable grip invite extended shooting sessions. Thanks to a fully articulating 3-inch touchscreen display and a sharp, bright electronic viewfinder (EVF) with 2.76M dots resolution, the GX7 excels for careful composition and intuitive handling.

In contrast, the S2 is a small sensor compact camera weighing just 112 grams, barely a third of the GX7. Its fixed lens design and lightweight plastic body make it extremely portable and pocketable but sacrifice extensive handling options. The fixed 2.7-inch screen is lower resolution at just 230k dots and lacks a viewfinder, which may hinder framing in bright daylight.

If you prioritize a camera that feels like an extension of your hand with tactile dials and buttons, the GX7 is clearly superior. Meanwhile, the S2 is for when ultra-portability and ease-of-use take precedence over manual control.

Sensor and Image Quality: The Heart of the Camera

Image quality largely depends on the sensor technology and image processor. The GX7 features a 16MP Four Thirds CMOS sensor measuring approximately 17.3x13mm with a sensor area of ~225mm². This sensor is paired with Panasonic’s Venus Engine processor, enabling solid dynamic range performance and color depth, resulting in sharper details and cleaner images up to ISO 25600 - though image quality naturally starts to degrade at higher sensitivities.

Conversely, the S2 uses a much smaller 1/2.3" CCD sensor (6.08x4.56mm, ~28mm²) with 14MP resolution. This sensor size is typical for compact cameras but inherently limits dynamic range, low-light performance, and depth of field control.

To put this in perspective: the GX7’s sensor is nearly eight times larger in area than the S2’s, which translates to:

• Far better noise handling at high ISO
• Superior dynamic range to retain details in shadows and highlights
• Greater control over depth of field for creative bokeh effects

In day-to-day shooting and controlled lighting, the S2 will still deliver decent snaps, but for professional-quality portraits or landscapes requiring fine details, the GX7’s sensor is the clear winner.

Control Layout and User Interface: Making Photography Intuitive

One of my favorite things about the GX7 is its smart control architecture. The top plate features a well-organized dial and dedicated exposure controls, allowing for fast aperture and shutter adjustments mid-shoot. A bonus is the tilting touchscreen LCD for high- or low-angle shots, which also supports touch focus. You get an EVF with complete 100% coverage and 0.7x magnification, very helpful for precision framing.

The S2’s interface is minimal, with no touch support and a simple fixed LCD. Lacking an EVF, you’ll rely on the screen alone, which suffers under sunlight glare. The compact size limits physical controls to basics.

If manual exposure tweaking and quick access to settings matter to you, the GX7 is the standout. The S2, on the other hand, focuses on point-and-shoot convenience.

Autofocus and Shooting Speed: Capturing the Moment

Autofocus systems significantly impact your ability to capture sharp images in a variety of situations.

The GX7 employs a contrast-detection AF system with 23 focus points and face detection, and supports continuous AF for tracking subjects. While not as advanced as today’s hybrid phase-detection systems, during my testing, it provided accurate and consistent focus - even in moderate low light. Continuous shooting tops out at a solid 5 frames per second, enough for casual action or street shooting.

The S2’s AF is contrast-detection only, with no continuous AF or tracking capabilities. Focus points are limited, and autofocus speed is noticeably slower, making it less suitable for fast-moving subjects.

For sports, wildlife, or any genre where capturing decisive moments is key, the GX7’s autofocus and burst speed offer a clear advantage. The S2 fits more leisurely shooting where speed isn’t critical.

Lens Selection and Compatibility: Creative Flexibility

A major consideration is the lens ecosystem - particularly for a mirrorless system like the GX7 with an interchangeable lens mount.

Being a Micro Four Thirds camera, the GX7 offers access to Panasonic’s extensive lineup and Olympus’s lenses, numbering over 100. This gives you versatility from ultra-wide, prime portrait lenses to long telephotos for wildlife and sports. You can adapt lenses from other mounts as well.

The S2 has a fixed 28–112mm f/3.1–6.5 zoom lens built-in, offering a 4× zoom range equivalent to 160–672mm in 35mm terms due to the smaller sensor’s crop factor of approximately 5.9. While convenient, this optics choice is limited compared to the GX7’s interchangeable options and smaller aperture range.

If you foresee developing your photography skills or need specific lenses for genres like macro, telephoto wildlife, or wide-angle landscapes, the GX7’s Micro Four Thirds mount is a huge plus.

Build Quality and Weather Resistance: Durability in the Field

Neither camera offers professional-grade weather sealing. The GX7 features a solid metal chassis with a premium feel, but lacks dust or moisture resistance. The compact S2’s plastic build and tiny form factor offer no environmental protections either.

If you shoot outdoors regularly and need weather resistance, neither option is perfect - but the GX7’s build is more robust and likely to survive general wear and tear better.

Battery Life and Storage: Keeping Up with Your Shoot

Battery capacity affects how long you can work without swapping power cells. The GX7 estimates about 350 shots per charge, which aligns with typical mirrorless performance of its generation. The S2 does slightly less at around 280 shots due to compact size limitations.

Both cameras use SD/SDHC/SDXC cards in one slot - standard and broadly compatible.

Video Capabilities: Recording Quality and Features

Video quality often surprises buyers who want both stills and moving image potential.

The GX7 captures Full HD 1080p footage at 60, 50, 30, and 24 fps using MPEG-4 and AVCHD formats. The inclusion of manual exposure control and a tilting touchscreen makes framing and adjusting on the fly smooth. However, it lacks microphone or headphone jacks, limiting audio control for serious videographers.

The S2’s video tops out at 720p HD at 30 fps, in Motion JPEG format which is processor-heavy and results in larger files. It also lacks manual exposure modes and any external audio inputs.

For casual video, the S2 suffices, but for more considered production or hybrid photo/video use, the GX7 grants more versatility.

Special Features and Connectivity: Modern Conveniences

Wireless connectivity on the GX7 includes built-in Wi-Fi and NFC for quick image transfer and remote shutter release, a feature sorely missing on the S2.

Tilting touchscreens, exposure bracketing (AE and white balance), sensor-based image stabilization (IBIS) on the GX7 enhance shooting flexibility. The S2 offers basic optical image stabilization relying on lens elements, less effective overall.

Price-to-Performance: What’s the Bang for Your Buck?

At a current price around $1000 for the GX7 and $109 for the S2, the value leap is pronounced but understandable due to vastly different classes.

You’re paying a premium for the comprehensiveness and quality the GX7 offers, while the S2 is an entry-level snapshot camera suitable for travelers or casual users.
