Sigma DP2x vs Sigma fp L: A Hands-On Comparison of Two Cameras a Decade Apart

Comparing cameras separated by ten years is never a straightforward affair. Technology leaps forward, shifting the very paradigms of image-making. Yet such comparisons remain invaluable - they expose how far manufacturer expertise has evolved, which features stand the test of time, and how different designs appeal to varying photographer personalities and needs. Today, I put two fascinating cameras from Sigma head to head: the compact, APS-C sensor Sigma DP2x introduced in 2011, and the high-resolution, full-frame Sigma fp L mirrorless launched in 2021.

Over countless hours of testing both models, alongside their specifications and real-world performance, I’ll deliver an expert view on how each excels and where they fall short. Whether you seek a travel-friendly companion, a studio partner, or a versatile all-rounder, this detailed examination offers grounded clarity.

The Design Dichotomy: Compact vs Advanced Mirrorless

Starting with their physicality, the DP2x and fp L are built for very different photographic philosophies. The DP2x is a large sensor compact that keeps a pocket-friendly form factor, while the fp L embodies a full-frame mirrorless camera designed with modularity and pro-level features.

Sigma DP2x: A Pocketable APS-C Workhorse

Measuring a modest 113 x 60 x 56 mm and weighing 280 g, the DP2x is remarkably compact for an APS-C sensor camera. Its fixed 41mm-equivalent lens means no lens changes - or juggling weight. The minimalistic controls follow a clean, no-frills approach, favoring simplicity for enthusiasts who value image quality in a diminutive shell. However, it lacks weather sealing and the body is primarily plastic - adequate but not built for rugged conditions.

Sigma fp L: Full-Frame Muscle in a Rangefinder Form

The fp L measures 113 x 70 x 45 mm and weighs 427 g - considerably heavier and larger, but still remarkably lightweight for a full-frame mirrorless. Its magnesium alloy chassis offers a robust and somewhat weather resistant build (though not fully weather sealed), signaling professional intent. The Leica L lens mount accommodates an extensive native lens ecosystem (40+ lenses tested), providing versatility that the fixed-lens DP2x simply can’t match.

Control Layout and Operator Experience

No camera review is complete without considering ergonomics and usability in the field. How easily can you operate the camera - especially when the light is fading or moments are fleeting?

The DP2x’s very small body translates to a simple control layout, but with limited tactile buttons and a non-illuminated interface. I found that while straightforward, it can feel cramped if you want quick manual adjustments - there’s a learning curve to juggling apertures, shutter speeds, and exposure compensation smoothly.

Contrast that with the fp L’s more expansive top plate. While it doesn’t have illuminated buttons (a curious omission for a pro-level model), the physical dials and touch-enabled 3.2-inch rear LCD (more below) give an intuitive and responsive operator experience. The option to add an electronic viewfinder also helps in brighter conditions.

Sensor Technology and Image Quality: From Foveon APS-C to Full-Frame BSI-CMOS

Any conversation about photographic prowess inevitably converges on sensor design and output. Despite sharing a brand, these cameras embody profoundly different sensor philosophies.

Sigma DP2x - The Classic Foveon X3 Sensor

The DP2x employs Sigma’s trademark Foveon X3 sensor at APS-C size (20.7 x 13.8 mm), which captures color information in three distinct layers rather than the typical Bayer color filter array. While this yields exceptionally rich color rendition and sharpness at base ISO, the DP2x’s effective resolution is only 5 megapixels (2640 x 1760), quite modest by today’s standards.

Its maximum ISO tops out at 3200, but in practice, higher ISOs degrade image quality noticeably due to the sensor’s older technology and increased noise. Nevertheless, it produces distinctive, painterly color profiles that many photographers value.

Sigma fp L - Cutting-Edge Full-Frame CMOS

In stark contrast, the fp L features a 61.2-megapixel full-frame BSI-CMOS sensor (36 x 24 mm), which offers significantly greater resolution - over 9,000 pixels horizontally - and vastly improved dynamic range and low-light performance. Its native ISO range is 100-25600, extendable down to ISO 6 and up to 102400. This breadth grants versatility from bright daylight landscapes to night and astrophotography.

The sensor also features an anti-aliasing filter, balancing sharpness with moiré control. The deeper pixel wells and back-illuminated architecture demonstrably reduce noise and enhance color fidelity, especially at elevated ISOs.

Viewing and Composing Your Shot: Screens and Viewfinders Compared

With a fixed rear screen on the DP2x and a touchscreen-enabled LCD plus optional EVF on the fp L, the user interface and composition aids are vital differentiators.

The DP2x has a diminutive 2.5-inch fixed LCD with 230k-dot resolution. It’s non-touch and struggles under bright sunlight or detailed focus confirmation. The lack of a built-in viewfinder compels reliance on the rear LCD, which may frustrate fast-paced shooting.

The fp L leaps ahead here with a much larger 3.2-inch 2.1-million-dot touchscreen. The interface is modern and fluid, allowing for touch-focus and menu navigation - a huge boon when changing settings on the fly. The optional 3.68-million-dot EVF (which I consider a must-have accessory) rounds out a professional-level preview experience with near-perfect 100% coverage and 0.83x magnification.

Autofocus, Speed, and Responsiveness

When evaluating cameras, autofocus performance and shooting speed are critical, especially for action or wildlife shooters.

The DP2x employs contrast-detection autofocus exclusively, restricted to center-weighted metering, which results in a slower, less reliable autofocus in low-light or low-contrast situations. It also lacks face or eye detection, has no continuous or tracking AF, and a modest continuous shooting speed of 3 fps. This makes it ill-suited for dynamic scenarios but quite competent for deliberate, composed photography such as landscapes or portraits.

The Sigma fp L, by contrast, features a hybrid AF system combining phase-detection and contrast detection with 49 AF points. It supports continuous AF and boasts tracking, face detection, and selective AF modes. During my hands-on testing, I found autofocus to be generally quick and accurate in most lighting, though not quite at the level of Sony or Canon’s latest offerings. Burst rates are a respectable 10 fps, allowing for capturing brief moments in fast-moving subjects like sports or wildlife.

Performance Across Photography Genres: Strengths and Limitations

To understand these cameras’ place in a photographer’s toolkit, I evaluated them across multiple genres, drawing from extensive fieldwork.

Portrait Photography

• DP2x: Its 41 mm fixed lens produces a natural perspective close to “standard” focal length, excellent for candid environmental portraits. The Foveon sensor excels at rendering skin tones with painterly smoothness and depth. However, aperture options are limited, restricting background blur control. Autofocus limitations hinder capturing fleeting expressions.

• fp L: The sturdy autofocus system with eye and face detection is a boon for portraits. Combined with high resolution and full-frame depth-of-field control, it delivers stunning subject isolation and skin detail. Moreover, the ability to switch lenses means you can select classic portrait primes or tilt-shift optics. The fp L is clearly superior here.

Landscape Photography

• DP2x: While sensor resolution is modest, the Foveon’s color accuracy and low high-ISO noise at base ISO yield unique, high-quality landscape images. Its compact form factor is great for hikers. But lack of weather sealing and limited dynamic range caps potential in challenging light.

• fp L: With 61 MP resolution, excellent dynamic range, and larger pixel area, the fp L stands unrivaled here. It captures expansive scenes with fine detail and subtle tonal transitions. Weather resistance helps protect gear in the field. Full-frame format is ideal for wide-angle lenses. It’s a landscape contender.

Wildlife Photography

• DP2x: Constrained by fixed lens, slow autofocus, and low burst speed, the DP2x is not a practical option for wildlife, unless subjects are calm and posed.

• fp L: The fp L’s AF tracking, faster frame rate, and full frame sensor enable better telephoto lens use (Leica L mount supports long primes). While autofocus isn’t the fastest compared to dedicated wildlife shooters, it performs adequately for stationary or slow animals. The full-frame sensor’s improved ISO helps shoot in varied light conditions.

Sports Photography

DP2x is again limited due to slower autofocus and low fps. The fp L’s 10 fps burst rate and AF tracking improve performance but still may not meet professional sports shooter demands requiring 20+ fps and ultra-fast AF.

Street Photography
