Panasonic LX100 II vs Sigma DP2: An Expert’s Take on Two Large Sensor Compacts from Different Eras

When it comes to large sensor compact cameras, the landscape is peppered with intriguing options that blend portability with image quality - though each with its own quirks and priorities. Today, we're diving deep into a comparison between two such contenders from very different corners of photographic history and technology: the Panasonic Lumix DC-LX100 II, launched in 2018, and the older, but still noteworthy, Sigma DP2, which debuted in 2009.

At first glance, these cameras might seem like odd bedfellows: one is decisive about versatile usability and video prowess; the other a niche specialist with unique sensor tech. But both are housed in compact form factors featuring large sensors, catering to photographers keen on image quality without lugging around DSLRs or mirrorless rigs.

I’ve had the pleasure (and occasional frustration) of putting both through their paces extensively, measuring them against the demands of diverse photographic disciplines. From portraiture to wildlife, landscapes to street scenes, and macro to astrophotography, this article aims to unpack how each performs in real-world use. I’ll also provide a practical take on ergonomics, lens options, connectivity, and value, helping you decide which suits your photographic style best.

How They Stack Up Physically and Ergonomically

Let’s start with the obvious: what these cameras feel like in your hands - the tactile experience that shapes every shooting session.

Looking side-by-side, the Panasonic LX100 II is marginally bulkier and heavier (392g vs. 280g), thanks to its larger battery and more advanced internal components. The Sigma DP2 feels more minimalist and pocketable, although its boxy shape might not inspire ergonomic comfort for extended shoots.

If you appreciate a solid grip and a bit of weight to steady your aim, Panasonic’s magnesium alloy body gives the LX100 II a reassuring heft. I found the rubberized textured grip particularly helpful during long outdoor shoots, where hand fatigue starts to creep in. The DP2, with shallower contours, is lighter but can feel toy-like compared to modern compacts, demanding more care in handling.

Control Layout and User Interface: Man's Best Companion or Forgotten Button?

Designers clearly had different philosophies here.

The LX100 II bucks the minimalism trend and embraces complexity, offering dedicated dials for shutter speed, exposure compensation, and aperture ring on the lens barrel. For a guy like me who enjoys tactile control without diving into menus, this is a blessing. That said, the absence of illuminated buttons in dim conditions is a mild downside, though the customizable function button helps streamline workflow.

On the flip side, the Sigma DP2's minimalist top deck keeps things simple - just a shutter release, mode dial, and no physical aperture ring (aperture is fixed on the lens). This simplicity comes at the cost of limited quick-access controls, pushing you into menus to adjust settings. For a photographer who relishes manual exposure tweaks on the fly, this can feel restrictive.

Live view operation does exist on both, but the Panasonic incorporates a touchscreen interface, making navigation more intuitive - especially for those used to smartphones - while the Sigma sticks to button presses and toggles.

Sensor Technology and Image Quality: The Heart of the Matter

Here’s where the debate really thickens.

Panasonic employs a 17-megapixel Four Thirds CMOS sensor measuring 17.3 x 13 mm, married with the efficient Venus Engine processor. Sigma opts for its idiosyncratic Foveon X3 APS-C-sized CMOS sensor, measuring 20.7 x 13.8 mm but only producing a 5MP output resolution.

Diving deeper, the Foveon sensor captures color information in a way no other sensor does: it records red, green, and blue photons at different silicon depths rather than using Bayer filter interpolation. This grants Sigma a reputation for exceptional color fidelity and detail rendition at low ISO settings but can reveal some limitations in noise handling and dynamic range.

In practical testing, the LX100 II’s images struck me as generally more balanced - with a wider dynamic range across shadows and highlights, thanks to designing for versatile shooting situations. I tested both cameras using standardized exposure sweeps and found the Panasonic’s sensor upheld cleaner details beyond ISO 1600, whereas the DP2 started showing pronounced noise even at its native ISO 200-400 range.

The LX100 II’s maximum image resolution of 4736x3552 (approximately 17MP) also allows larger prints and cropping flexibility, while the Sigma’s 2640x1760 resolution, though smaller, delivers impressively sharp output within its pixel count due to the Foveon’s no-bayer-filter design.

Those who prize color accuracy above all - and mainly shoot static subjects - might prefer the DP2’s output, but the LX100 II wins on practical everyday quality and higher resolution.

Try Me, Autofocus: Who’s Quicker to Nail the Shot?

Both cameras feature contrast detection autofocus systems - but that’s about where the similarities end.

The Panasonic LX100 II sports a multi-point AF system with 49 focus points, face detection, and continuous tracking modes. It also supports touch-to-focus on its LCD. This gives it solid real-world speed and reliability even in moderately low light - ideal for quick candid portraits or street photography.

Conversely, the Sigma DP2 relies on a slow contrast-detection-only AF with a single focus mode and no face or eye detection assistance. In practice, this means you’re often nudging the focus manually, especially in dim conditions or fast-moving scenes. Its slow AF motor verges on frustrating if you’re chasing fleeting moments in wildlife or sports; it’s best suited for deliberate, composed shots - think still life or landscapes.

Viewing and Composing: Viewfinders and Screens

Let’s talk composition aids. Here’s the Panasonic LX100 II’s clear advantage:

The LX100 II features a bright 3-inch 1240k-dot touchscreen LCD paired with a sharp electronic viewfinder (EVF) - 2.76 million dots at 0.7x magnification, covering 100% of the frame. This combination provides excellent collaborative framing in bright daylight and a comfortable eye point even for eyeglass wearers. The touchscreen is responsive, making menu adjustments and focus selection easy when handheld.

The Sigma DP2 sports a smaller, low-res 2.5-inch LCD at just 230k dots, no touchscreen, and no EVF at all. Composing under sunlight requires shading the screen or guessing. Though the LCD is adequately bright indoors, it’s a significant limitation for precise framing or reviewing shots in varied lighting conditions.

Lens Versatility and Optics

Both cameras come with fixed lenses, a blessing and curse for portability but a challenge for adaptability.

• LX100 II: 24–75mm equivalent zoom with a bright variable aperture from f/1.7 to f/2.8.
• DP2: 41mm equivalent prime lens at a fixed aperture (Sigma doesn’t specify max aperture, but it’s around f/2.8).

The LX100 II’s zoom range combined with the bright lens lets you experiment across wide-angle landscapes, portraits, and short telephoto - ideal for travel photographers craving flexibility. I’ve appreciated its smooth, fast aperture transitions for subject isolation and bokeh-rich portraits, especially when paired with Panasonic’s aperture ring and focus modes.

The Sigma DP2, with its fixed 41mm lens, demands thoughtful composition and limited framing adjustments (you move your feet for crop or different perspectives). Its optic, however, is razor-sharp and designed exclusively to maximize the Foveon sensor’s characteristics. The distinct rendering style produces images with a painterly quality, attracting enthusiasts of fine art photography - but this lack of versatility may jar users accustomed to zooms or multi-lens systems.

Battery Life and Storage: Practical Necessities

Battery life is often overlooked but can ruin a day of shooting if underestimated.

The Panasonic LX100 II uses a rechargeable DMW-BLE9 lithium-ion battery offering approximately 340 shots per charge. This isn’t stellar compared to DSLRs but respectable for a compact packing a large sensor and EVF. Its USB charging compatibility also boosts convenience on the go - a nice touch for travelers.

The Sigma DP2’s battery specifications are vague (it even lacks a specified model), but in my testing, the rated shots per charge fell closer to 200-250, owing to the older electronics and small body limiting battery size.

Both cameras accommodate a single SD card slot, compatible with standard SD, SDHC, and SDXC cards. Panasonic supports UHS-I speeds useful for 4K video and burst shooting; Sigma’s slower data pipeline reflects its more modest still photo focus.

Connectivity and Modern Workflow

In 2024, wireless features are practically mandatory for fast image sharing and remote control.

Panasonic LX100 II delivers built-in Wi-Fi and Bluetooth connectivity, enabling image transfer to smartphones, remote triggering via apps, and firmware updates over the air. The HDMI port offers clean video output for content creators - a boon for modern workflows.

The Sigma DP2 offers none of these, lacking wireless capabilities altogether, HDMI output, even USB 3.0. It feels decidedly last decade in this respect, making it less suited for instantly sharing shots or integrating into complex workflows without manual card swaps.

Video: Can They Handle Moving Pictures?

If you do video often, the Panasonic LX100 II is an obvious winner.

It shoots clean 4K UHD footage at 30p @ 100 Mbps (MP4, H.264, AAC), which is a major plus for vloggers or creative videographers wanting high quality from a compact. Panasonic’s Venus Engine helps reduce noise and improve overall video clarity.

Sigma DP2 has a video mode capped at a miserable 320 x 240 resolution at 30fps in Motion JPEG format - essentially a novelty rather than a tool for serious video. It’s fair to say this camera was never intended as a video companion.

Real-World Use Across Photography Genres: Who Does What Best?

Time for a thorough brushstroke across different photography styles to put theory into action.

Portrait Photography

• Panasonic LX100 II: The versatile zoom and bright aperture shine here. Eye detection autofocus locks quickly in good light, while subtle bokeh transitions in portraits help separate subject and background. Colors are natural and skin tones pleasing, particularly when shooting in RAW and tweaking in post.
• Sigma DP2: The 41mm prime’s sharpness yields detail-packed portraits, but relying on manual focus or slow AF makes it challenging to capture fleeting expressions - better suited for posed studio-like work.

Landscape Photography

• LX100 II: Offers variable focal lengths to capture wide scenes or compressed views. Its sensor balances resolution and dynamic range to hold shadow detail and recovery latitude.
• DP2: The Foveon sensor delivers breathtaking color depth, ideal for static, controlled landscape compositions - but limited resolution and slow operation restrict spontaneity.

Wildlife and Sports Photography

Honestly, neither shines here, but Panasonic is the clear winner if you must choose:

• LX100 II’s 11 frames per second burst and decent AF tracking help grab fast action within reason.
• DP2’s 3 fps max, sluggish focus, and fixed lens are ill-equipped for dynamic subjects.

Street Photography

• DP2’s smaller size and discreet look benefit street shooters wanting to fly under the radar, but slow AF can lead to missed moments.
• LX100 II’s faster AF and EVF give more shooting confidence but are less inconspicuous.

• The Panasonic offers a 3cm macro focus range with optical image stabilization lending sharper handheld shots.
• Sigma lacks a dedicated macro focus, limiting close-up shooting capability.

Night and Astro Photography

Low-light performance favors the In-house tech:

• Panasonic’s higher ISO performance and wider aperture help capture stars and night scenes with less noise.
• Sigma’s low maximum ISO and narrow aperture limit night photography strongly.

Travel Photography

Here, the LX100 II is made for you: a balanced zoom lens, good battery life, rugged build, and compact but ergonomic design.

The DP2’s artistic image output could appeal to wanderers seeking a particular style - but practical constraints like poor battery, clunky controls, and single focal length may frustrate long trips.

Reliability, File Formats & Professional Integration

The Panasonic’s support for RAW files (RW2 format), versatile exposure modes, focus bracketing, and stack focus features suit professional workflows. USB charging and Wi-Fi help keep pace with on-location demands.

Sigma also supports RAW (X3F format), but software support isn’t as widespread, and workflow integration might feel clunky.
