The Sigma DP2 Quattro vs Sony NEX-5N: A Deep Dive into Two Distinct APS-C Cameras

Choosing your next camera often feels like standing at a crossroads, especially when options come from different eras and design philosophies. I’ve had the opportunity to extensively test both the Sigma DP2 Quattro and the Sony NEX-5N - two APS-C sensor cameras born roughly three years apart, yet aimed at enthusiasts craving high image quality, each from very different directions. With over 15 years evaluating cameras professionally, I want to guide you through an honest, hands-on comparison of these two to help you understand which might fit your photography ambitions.

Seeing Is Believing: Size and Handling

At first glance - and by feel - the Sigma DP2 Quattro and Sony NEX-5N couldn't be more different. The Sigma DP2 Quattro is a large sensor compact with a fixed 45mm f/2.8 lens, designed for a very specific photographic purpose, while the Sony NEX-5N is a mirrorless system camera that takes interchangeable lenses over the expansive Sony E-mount range.

Sigma DP2 Quattro vs Sony NEX-5N size comparison

The Sigma DP2 Quattro feels solid and substantial in hand, weighing 395g with a body dimension of 161x67x82mm; it leans heavy for a compact camera. Its grip is generous but chunky which, along with its somewhat unorthodox angular body design, provides stability for deliberate shooting rather than rapid bursts. It gives the impression of a serious photographer’s tool - but not one you'd want in a pocket for street or travel use.

Conversely, the Sony NEX-5N weighs just 269g with a far more compact body at 111x59x38mm. This small footprint and lighter weight make it immensely portable and inviting for spontaneous photography. Its slim rangefinder style body feels nimble, perfect for travel or street shooting where stealth and quick reaction matter.

In hands-on use, the Sigma demands slower, more calculated operation, whereas the Sony encourages playfulness and responsiveness. If your shooting style values portability and ease, the NEX-5N wins here. Yet, if you’re methodical about image creation and want a tactile experience, the DP2 Quattro rewards patience.

Top Controls and Interface: Designed for Precision vs. Flexibility

Usability is key, and both cameras reflect very different control philosophies.

Sigma DP2 Quattro vs Sony NEX-5N top view buttons comparison

The Sigma DP2 Quattro’s minimalist top plate features a shutter button with a ring control around it, an exposure compensation dial, and a mode dial - clearly aimed at photographers who prefer to dial settings directly and avoid menu diving. However, the absence of an optical or electronic viewfinder pushes you toward composing on the fixed 3" screen without touch input. The controls feel deliberate rather than speedy, requiring time to get accustomed to their tactile response.

The Sony NEX-5N, being mirrorless with interchangeable lenses, provides a richer set of customizable buttons, a tilting 3" touchscreen (which aids in creative angles), and more accessible exposure control options. It lacks a built-in viewfinder but offers an optional external EVF - a noteworthy tradeoff. The autofocus system is user-friendly, supporting face detection and a broad array of focusing areas, plus touch AF. For fast-paced photography, especially street and casual portraiture, this flexibility matters.

Between these two, my experience finds the NEX-5N better suited for dynamic shooting environments needing quick tweaks, while the Sigma’s controls cater well to focused, contemplative image-making sessions.

The Heart of the Image: Sensor and Image Quality

A true showstopper when comparing these two is their fundamentally different approach to sensing light and rendering images.

Sigma DP2 Quattro vs Sony NEX-5N sensor size comparison

The Sigma DP2 Quattro employs a unique Foveon X3 CMOS sensor - notable for capturing full color information across three stacked photodiode layers at every pixel. This sensor measures 23.5 x 15.7mm (APS-C class) and offers an effective 20 megapixels (unique to its design, not directly comparable to Bayer sensors). The Foveon sensor’s strength is razor-sharp detail and exceptionally accurate color reproduction, especially skin tones, thanks to its direct color interpretation without a Bayer filter array.

In contrast, the Sony NEX-5N uses a traditional Bayer APS-C CMOS sensor (23.4 x 15.6mm, 16MP). This sensor is well-regarded for dynamic range, high ISO performance, and overall speed due to mature CMOS technology. Having tested both at ISO 100 through native ISO 6400 and beyond, I found the Sony delivers superior low-light versatility and cleaner images at elevated ISO settings, thanks to conventional noise reduction processes.

While the Sigma’s Foveon excels in daylight and controlled lighting with ultra-fine texture capture and color depth - ideal for studio, portrait, and landscape work - the Sony shines in versatility, better noise control, and higher burst rates, making it more practical for general shooting conditions and lower-light environments.

Composing and Reviewing Images: Screens and Viewfinding

In real-world shooting, your interface to composing and reviewing images is pivotal.

Sigma DP2 Quattro vs Sony NEX-5N Screen and Viewfinder comparison

Both cameras feature a 3" LCD with 920k dot resolution, which is fairly sharp for their era. However, the Sony’s screen tilts - an enormous boon for shooting at awkward angles, including street candid shots or low-level still-life work - while the Sigma’s LCD is fixed at a single angle.

The NEX-5N also provides touch-focus capabilities, which dramatically improves focusing speed and ease, particularly in spontaneous shooting. The Sigma lacks a touchscreen and limits autofocus to contrast detection with only nine focus points and no continuous AF, which slows responsiveness but further cements its deliberate usage style.

Neither camera includes a built-in viewfinder, but Sony offers an external EVF option. I highly recommend using it outdoors on the NEX-5N for better visibility under harsh sunlight - a scenario where the Sigma’s fixed TFT screen can become difficult to see.

Who’s Better at What? Genre-by-Genre Performance

Looking at the photography disciplines that you may pursue, here’s my detailed take based on extensive field testing:

Portraiture: Skin Tones and Bokeh Magic

The Sigma DP2 Quattro, with its 45mm fixed lens (effectively ~68mm in 35mm terms), offers an optimal portrait focal length. The Foveon sensor combined with the lens’s optical performance produces portraits with incredible color fidelity and detail, rendering skin naturally and smoothly without heavy post-processing.

However, at f/2.8 maximum, the bokeh is pleasant but not as creamy or shallow as lenses with wider apertures; the fixed lens limitation can be a con. The Sony NEX-5N, paired with the vast E-mount lens ecosystem, enables you to choose faster lenses (like 50mm f/1.8 or even f/1.4 options), granting more background separation. Sony’s face and eye detection AF also help nail focus quickly on subjects' eyes, a huge advantage for portrait shooters.

Landscape: Dynamic Range and Resolution

Sigma’s Foveon sensor delivers exquisite micro-detail, invaluable for landscapes that reward ultra-high resolution and color detail for large prints. However, limited dynamic range relative to traditional sensors requires careful exposure techniques. The Sigma’s lack of in-body image stabilization (IBIS) means tripods are essential for sharp landscapes in low light.

Sony's NEX-5N provides better dynamic range and slightly higher pixel count of 16MP, sufficient for gorgeous 16x20 prints, with more forgiving shadow recovery and highlight retention. Its weather-sealing is nonexistent, which should be considered if you shoot in harsh conditions.

Wildlife and Sports: Autofocus Agility and Frame Rates

The Sigma DP2 Quattro has a maximum 3 fps burst, single-shot contrast AE autofocus only, and only 9 focus points - far too limited for moving subjects like wildlife or sports.

The Sony NEX-5N steps up with a 10 fps continuous shooting rate and a more versatile AF system with 25 focus points, face detection, and Live View phase detection (although limited). While not a dedicated sports camera, NEX-5N is substantially better at tracking moving subjects, helping you get sharper shots in more dynamic scenarios.

Street and Travel: Discreteness and Portability

The Sony’s smaller size, lighter weight, tilting touchscreen, and interchangeable lenses afford tremendous street credibility. I’ve used mine for years capturing fleeting moments in crowded cityscapes without drawing attention.

The Sigma’s bulk and non-tilting screen make it less convenient for street photography, but I found its discreet shutter sound and fixed prime could aid in slow shooting sessions when subtlety counts. For travel, battery life is another factor: NEX-5N offers roughly 460 shots per charge compared to the unknown, likely less generous life on the Sigma.

Macro, Night, and Video Capabilities

Neither camera is a macro specialist, but here's how they stack up:

  • Macro: Sigma’s fixed lens doesn’t offer macro capability; Sony’s lens ecosystem includes dedicated macro lenses. Thus, macro enthusiasts would lean on the Sony system for close-up capabilities.

  • Night and Astro: Sigma's limited max ISO and slower shutter speeds (max 1/2000s) can be restrictive; no built-in stabilization adds to challenges. Sony offers much higher ISO (up to 25600), which paired with good noise handling opens night shooting possibilities. Neither is ideal for astrophotography but Sony's sensor is more versatile for long exposure and low-light.

  • Video: Sigma DP2 Quattro has no video mode - a significant limitation today. The NEX-5N offers 1080p full HD video at 60fps, with AVCHD format support and HDMI output, making it a capable hybrid stills/video tool for casual filmmakers.

Build Quality and Weather Resistance

Neither model offers environmental sealing, dustproofing, or weather resistance, so both require care in challenging climates. The Sigma’s physical heft and solid feel suggest durability, whereas the lightweight Sony feels more delicate but is still well constructed.

Lens Ecosystem and Expandability

This comparison hinges on fixed vs. interchangeable lenses - a fundamental differentiation:

  • Sigma DP2 Quattro: Features a single fixed lens (45mm f/2.8) crafted for exceptional optical quality, but no flexibility to change focal lengths or add accessories beyond an external flash.

  • Sony NEX-5N: The E-mount lens ecosystem, even at release, included over 100 lens options from wide-angle primes to telephoto zooms and specialty lenses. Lens choice drastically extends creative potential.

Workflow, Connectivity, and Storage

The Sigma DP2 Quattro has limited connectivity options - no wireless features, only USB 2.0 for file transfer, and one storage card slot. Battery life data is sparse, but users report modest performance.

The Sony NEX-5N, on the other hand, supports Eye-Fi wireless SD cards, HDMI output, USB 2.0, and wide file compatibility. Battery life of approximately 460 shots per charge is considerably better for prolonged shoots.

Price and Value Assessment

At launch pricing, the Sigma DP2 Quattro retailed around $930, almost double the Sony NEX-5N’s $550 street price. Sigma targets photographers prioritizing image quality in a dedicated compact form, while Sony delivers versatility and affordability.

In my experience, the Sony NEX-5N offers a compelling entry point into APS-C mirrorless photography with benefits across more genres, whereas the Sigma DP2 Quattro demands a niche commitment to meticulous, studio-quality images.
