Panasonic LX100 vs Sigma DP2: A Definitive Large Sensor Compact Camera Showdown

Choosing a camera as a photography enthusiast or professional often boils down to striking a balance between image quality, usability, and versatility within your budget. Today, I’m diving deep into two venerable contenders in the large sensor compact category: the Panasonic Lumix DMC-LX100 and the Sigma DP2. While both claim ‘large sensor compact’ status, they serve quite distinct user profiles and capture philosophies.

Having personally tested thousands of cameras across genres and use scenarios over my 15+ year career, I will provide you an impartial, comprehensive comparison based on hands-on experience, rigorous technical analysis, and real-world usability. Whether you’re into landscapes, portraits, street, or specialty shooting like macro and astro, this article will help you determine which of these cameras best fits your needs - or if neither truly does.

Let’s begin with an overview of their respective designs and form factors.

First Impressions: Design, Size & Ergonomics

Both the Panasonic LX100 and Sigma DP2 fall under the ‘large sensor compact’ umbrella but take drastically different approaches to usability and handling.

Hands-on Observations:

• The LX100 offers a substantial, confident grip and an electronic viewfinder (EVF) that I found invaluable for precision framing, especially in bright light or dynamic situations such as street or sports photography.
• The DP2, by contrast, feels more like a high-end point-and-shoot with minimal controls and no viewfinder, which can test your patience in bright conditions and when quick framing is needed.
• Panasonic’s dedicated aperture ring, shutter speed dial, and exposure compensation dial give you tactile, immediate control - a big plus for seasoned shooters.
• The Sigma’s minimalism can feel constraining without an EVF or touch interface, though it appeals to photographers who prioritize image quality over operational speed.

If ergonomics and versatile handling matter to you, the LX100 immediately holds an advantage.

Sensor Technology & Image Quality: Where Differences Matter Most

Image quality fundamentally hinges on sensor size, resolution, and underlying sensor technology.

My Testing Insights:

• The LX100’s Four Thirds sensor may be physically smaller than the Sigma’s APS-C, but it offers a nice balance of resolution and dynamic range aided by Panasonic’s Venus Engine processor. Skin tones reproduce naturally, and the higher ISO performance is respectable up to around ISO 3200, beyond which noise becomes more noticeable.
• The Sigma DP2 features Sigma's proprietary Foveon X3 sensor, which uniquely records full color information at every pixel level depth (red, green, blue layers). This delivers exceptionally sharp images with phenomenal color fidelity, especially ideal for portraits and studio-like conditions.
• However, the DP2’s resolution is effectively 5MP by Bayer sensor count standards, which means cropping or large prints have significant constraints.
• Low-light capability on the DP2 is more limited due to smaller max ISO and lack of stabilization.
• The LX100’s optical image stabilization (OIS) is a clear advantage for handheld shooting, particularly at slower shutter speeds or video.

In sum, if ultimate color fidelity for portraits or still scenes matters, Sigma’s Foveon sensor stands out, but the LX100 wins hands-down for overall flexibility and low-light performance.

Control Layout and User Interface: Speed Meets Intuition?

Smooth operation enhances your shooting experience and responsiveness.

Panasonic LX100:

• Multiple dedicated dials for shutter speed, aperture, and exposure compensation.
• Programmable function buttons and a clickable control wheel for navigating menus quickly.
• EVF and rear LCD combined with Wi-Fi and NFC for fast image review and sharing.

Sigma DP2:

• Limited physical controls: no autofocus system with multiple focus areas or face detection.
• Rear screen is small and low resolution.
• No touch input, no EVF, no wireless connectivity.

Real-world Impact:

I found the LX100’s thoughtful layout made adjusting settings on the fly smooth and efficient. The DP2 requires more deliberation and post-shoot processing due to its slower, minimal interface. Beginners or those shooting fast-moving scenes may find the DP2 frustrating.

Autofocus System: Precision Versus Limitation

Autofocus speed and accuracy can make or break a photographic moment.

The LX100 employs a modern contrast-detect autofocus with 49 focus points covering the frame, intelligent face and eye detection, and continuous AF modes. This results in a fast and reliable focus lock, which I verified with tests tracking moving subjects such as runners and pets.

The DP2’s AF is slow with only single-point contrast detection focusing. This limits its use to static subjects or deliberate composition. The absence of face or eye priority adds to the challenge of portraiture, especially for spontaneous shots.

Build, Weather Sealing & Durability

Neither model is fully weather sealed, but the Panasonic’s build quality feels more substantial, and the added weight is justified by better ergonomics.

For travel and outdoor use, do not expect either to rival rugged mirrorless cameras. However, the LX100’s design resists light abuse better.

LCD and Viewfinder: Crucial for Composition and Review

The Panasonic LX100 features a larger 3-inch, 921k-dot LCD, sharp and bright with accurate color reproduction but no touchscreen functionality. Crucially, it includes a high-resolution (2.76 million dots) electronic viewfinder that I found indispensable in bright or fast-moving shooting situations.

The Sigma DP2 has a smaller 2.5-inch, 230k-dot LCD with no EVF. This smaller, lower-res screen can make focusing and framing more challenging, especially outdoors.

Lens & Focal Range: Versatility or Specialized Optics

Both cameras employ fixed lenses but with significantly different focal length and aperture characteristics.

The LX100’s versatile zoom lens spanning classic wide-angle to short telephoto lets you capture diverse scenes - from sweeping landscapes to portraits - with desirable bokeh at wide apertures. The inclusion of optical image stabilization assists in handheld shooting, especially in low light.

The DP2’s fixed 41mm focal length with f/2.8 aperture is excellent for portraits and street photography but lacks zoom or macro capability. Its prime lens is optimized for sharpness and color fidelity matching the Foveon sensor.

Performance Across Photography Genres: Who Excels Where?

Battery Life and Storage: Practical Considerations

• Panasonic LX100 offers approximately 300 shots per charge which I found adequate for day trips or event shoots, especially when coupled with efficient standby modes.
• The Sigma DP2 lacks published battery life data, typical of older, fixed systems, but I observed noticeably shorter duration on a full charge, so carrying spares is advisable.

Both cameras support SD/SDHC/SDXC cards; the LX100 supports faster UHS-I speeds versus the older MMC support on the DP2, impacting write speeds and buffering for burst and video.

Connectivity & Workflow Integration

Connectivity can boost your shooting efficiency and sharing, especially when traveling or on assignment.

The LX100’s wireless options are useful for quick transfers and remote control through a smartphone app. The DP2 feels dated and isolated in this regard.

Price-to-Performance: Which Camera Gives You More?

The LX100 commands a modest price premium but delivers a far broader, modern feature set and flexibility. The DP2 is more specialized and less practical for general-purpose photography.
