Panasonic Lumix DMC-S1 vs. Pentax MX-1: An In-Depth Comparative Review for Small Sensor Compact Cameras

In the ever-evolving world of digital photography, small sensor compact cameras remain a popular choice for photographers seeking a balance between portability, ease of use, and decent image quality. Today, I’m diving into a detailed head-to-head comparison of two notable players in this category: the Panasonic Lumix DMC-S1 from 2011 and the Pentax MX-1 released in 2013. Both offer fixed lenses with identical focal ranges but differ significantly in features, ergonomics, and performance.

Having spent weeks putting these cameras through rigorous real-world and lab testing scenarios alongside technical analysis, this article aims to provide you with expert insights into their design, image quality, handling, and suitability across various photography disciplines. Whether you’re a budding enthusiast or a seasoned photographer seeking a reliable compact companion, understanding the trade-offs here is critical. Let’s start by taking a quick look at their physical presence.

Size, Build, and Ergonomics: Comfortable Handling vs. Classic Compactness

Right out of the gate, the physical feel of a camera shapes the entire shooting experience. The Panasonic S1 is incredibly diminutive by modern standards, weighing just 117g and measuring a slender 99 x 59 x 21 mm. In contrast, the Pentax MX-1 tips the scales at 391g with dimensions of 122 x 61 x 51 mm, making it noticeably larger and chunkier.

This size difference tells a tale of two design philosophies. The Panasonic's ultra-compact form factor is exemplary for those prioritizing pocketability and lightweight carry - ideal as a grab-and-go everyday camera. However, this comes with trade-offs: the ergonomics feel somewhat cramped, and the Panasonic lacks a protruding grip, which can affect stability during prolonged shooting sessions.

The Pentax MX-1 leans into a more robust build with a vintage-inspired, all-metal chassis that exudes solidity and durability. Its thicker body offers a comfortable, secure grip and makes room for more physical controls, appealing to photographers who prefer tactile interfaces over touchscreen fiddling. The MX-1’s comparatively heavier weight can either feel reassuring or burdensome, depending on your preference for heft.

So, ergonomically, the choice boils down to: do you want a featherlight, pocketable shooter (Panasonic), or a heavier but comfortable, retro-styled camera (Pentax)?

Top Controls and Interface: Manual-Focused vs. Simplicity

Let’s deep dive into user interface and controls, which significantly impact workflow, especially when shooting quickly in changing conditions.

The Panasonic S1 offers a pretty minimalist control layout on its top panel. It lacks dedicated manual exposure dials and instead relies on a GUI-driven approach, though it does support live view. With no manual focus ring or extensive physical controls, this camera targets casual users who want simplicity over granular control.

Conversely, the Pentax MX-1 embraces classic photography sensibilities with physical shutter speed dials, an aperture ring on the lens, and customizable function buttons. Manual focus is implemented with direct tactile feedback, granting enhanced precision for those who prefer traditional shooting methods.

From my time testing, the MX-1 offers a refreshing, hands-on shooting experience that elevates your engagement with the craft. Meanwhile, the Panasonic may feel limited to photographers comfortable with automated modes and minimal customization.

Sensor Technology: The Invisible Heartbeat of Image Quality

Both cameras feature a 12MP CCD or CMOS sensor, a standard for the era and sensor size class, but they aren't exactly twins under the hood.

• Panasonic Lumix S1: Uses a smaller 1/2.3-inch CCD sensor (6.08 x 4.56 mm), equating to just 27.72 mm² sensor area.
• Pentax MX-1: Employs a larger 1/1.7-inch BSI CMOS sensor (7.44 x 5.58 mm) - that’s about 41.52 mm², nearly 50% larger than the Panasonic's.

Larger sensor size directly correlates with better light-gathering capability, resulting in superior dynamic range, less noise, and improved low-light performance. The MX-1’s sensor benefits from back-illuminated design, giving it a technology edge over the S1's earlier CCD, which is more prone to noise and limited dynamic range.

Also notable: the MX-1 supports RAW file capture, allowing for extensive post-processing latitude. The Panasonic only shoots JPEGs with no RAW support, an important limitation for serious photographers wanting maximum flexibility.

In practical testing under varied lighting, the MX-1 renders cleaner images at higher ISOs, with deeper color fidelity and better shadow recovery. The Panasonic’s images tend to show more noise and compressed tonal gradations, especially above ISO 400.

Rear Screen and Live View: Usability and Viewing Comfort

Live view and rear LCD usability matter much for composition and reviewing shots, especially on compact cameras without electronic viewfinders.

The Panasonic S1 features a basic fixed 2.7-inch TFT LCD with a modest 230k-dot resolution, lacking touchscreen capabilities. The image appears somewhat dim and less crisp, making it less pleasurable or effective for precise framing, particularly in strong sunlight.

Meanwhile, the Pentax MX-1 offers a larger 3-inch tilting LCD with a significantly higher 920k-dot resolution and an anti-reflective coating, which improves visibility outdoors. The tilting mechanism adds creative flexibility - handy for low-angle shots or shooting above crowds.

This higher resolution screen and adjustable angle make the MX-1 far more comfortable and versatile for live view photography and menu navigation.

Autofocus Performance: Precision vs. Simplicity

Auto focusing is a key area where technology can make or break a user’s shooting experience. Neither camera sports phase-detection autofocus, instead relying on contrast-detection AF systems.

The Panasonic S1 comes with a simpler AF system that provides eleven basic focus points without face detection or tracking features. Autofocus speed is leisurely, and it doesn't support continuous or tracking AF. Predictably, in challenging lighting or dynamic scenes, the S1 will struggle - leading to missed focus opportunities.

The Pentax MX-1 improves upon this with 25 focus points and includes face detection and AF tracking capabilities, enhancing reliability and accuracy for moving subjects. It also supports single, continuous, and AF tracking modes. Manual focus is straightforward, with a dedicated focus ring allowing precise adjustments for macro or low-contrast subjects.

In wildlife or sports scenarios, the MX-1's AF system performs markedly better, capturing sharper images of fast-moving subjects. The Panasonic S1 is best reserved for static or slow-moving subjects due to slow and less accurate AF.

Lens Quality and Reach: Bright Optics vs. Range Limitations

Both cameras offer a fixed 28-112mm equivalent zoom - a modest 4x range - making them equally versatile for standard daily shooting.

However, maximum apertures differ substantially:

• Panasonic S1: f/3.1 – f/5.6
• Pentax MX-1: f/1.8 – f/2.5

The bright lens of the MX-1 is a major advantage, especially in low light and for shallow depth-of-field effects like creamy bokeh. The Panasonic lens, being slower, requires higher ISO or slower shutter speeds indoors or at dusk.

Macro capabilities also differ: the MX-1 focuses down to 1cm compared to Panasonic’s 5cm, permitting closer and more detailed close-up shots.

The MX-1’s lens is also known for being sharp edge-to-edge with minimal chromatic aberrations, whereas the Panasonic lens, while decent, is softer wide open and exhibits more distortion in the telephoto range.

Image Stabilization and Shutter Speeds: Stability Meets Flexibility

Both cameras provide image stabilization, but their types differ:

• Panasonic uses optical image stabilization.
• Pentax relies on sensor-shift stabilization.

Sensor-shift systems in the MX-1 are generally more effective across focal lengths and in macro situations, as the correction happens directly at the sensor. The Panasonic’s optical system works well for standard zoom but is less helpful at macro distances.

Regarding shutter speed flexibility:

• Panasonic’s shutter range: 8 – 1/1600 sec.
• Pentax MX-1: much wider at 30 – 1/8000 sec.

This wider range allows the MX-1 to freeze fast action better and facilitate longer exposures for night or creative effects without ND filters.

Video Capabilities: Modest vs. More Versatile

For users who want video as part of their camera’s function, these two diverge sharply.

Panasonic S1 shoots only up to 720p at 30fps, recorded as Motion JPEG - a dated, inefficient format yielding large file sizes and limited editing flexibility.

Pentax MX-1 provides full HD 1080p video at 30fps, along with 720p options up to 60fps, encoded in efficient MPEG-4/H.264. This translates to better video quality, smoother motion, and smaller file sizes conducive to easier editing.

Neither camera has external microphone inputs, so audio remains limited to built-in mics, which is a constraint for serious video makers.

Battery Life and Storage: Efficiency in Compact Packages

Battery endurance often gets overlooked but can impact long shoots significantly:

• Panasonic S1: About 240 shots per charge.
• Pentax MX-1: Slightly better at 290 shots.

While neither is spectacular, the MX-1 offers marginally longer shooting time, attributed to efficient processing and a larger battery.

Storage-wise, both support SD/SDHC/SDXC cards. The Panasonic includes internal storage - a nice fallback - though its capacity is small.

Connectivity and Extras: What’s Missing and What’s Useful

Neither camera boasts modern wireless features like Bluetooth or Wi-Fi. The MX-1 includes Eye-Fi card compatibility for wireless transfer - better than nothing for the era but limited compared to today’s standards.

The Pentax MX-1 outputs via HDMI, useful for tethered viewing or playback on external monitors, whereas the Panasonic S1 lacks this.

Putting It All Together: Performance Ratings

Based on my own lab testing combined with established third-party data, the MX-1 outperforms the Panasonic S1 in most categories. It excels especially in sensor quality, lens brightness, autofocus, video, and handling.

How Do They Stack Up Across Photography Types?
