Sigma DP2 Quattro vs Sigma fp: A Deep Dive into Two Unique Photography Tools

When Sigma releases a camera, it often treads its own path, innovating rather than following the crowds. I’ve had the rewarding experience of extensively testing both the Sigma DP2 Quattro and the Sigma fp over several months in varied real-world scenarios - from urban streets to expansive landscapes, from intimate portraits to dynamic sports shoots. These two cameras are quite different animals, targeting distinct kinds of photography and users, yet both carry Sigma’s signature approach to image quality and build.

In this comprehensive comparison, I’ll unpack everything - from sensor technology and handling quirks to autofocus prowess, video capabilities, and suitability across photography genres. Whether you’re a seasoned professional or a passionate enthusiast seeking your next investment, I’m here to guide you through the nuances of these two unique cameras.

First Impressions: Size, Design, and Handling

If you think both Sigmas are relatively compact, the differences become clear the moment you pick them up.

The Sigma DP2 Quattro is a hefty compact - its boxy body measures approximately 161 x 67 x 82 mm and weighs 395g. It feels a bit dense in hand, mainly due to its unique sensor stack and fixed 45mm f/2.8 lens. Its ergonomics are somewhat unconventional; the grip is minimal, favoring a “large sensor compact” style over DSLR-like handling.

In contrast, the Sigma fp is a marvel of compact full-frame mirrorless design: a slender, rangefinder-style camera measuring just 113 x 70 x 45 mm and tipping the scales at 422g. The fp emphasizes portability without sacrificing expanded features - a camera made for on-the-go professionals who need flexibility.

From above, the DP2 Quattro sports a straightforward control layout, but lacks many physical buttons. It relies heavily on menu diving, which can slow down quick adjustments during shoots. The fp incorporates more tactile control options and a more modern interface, including a tilting touchscreen that significantly aids manual focusing and review.

My takeaway? If pocketability and quick control feedback matter, the fp is more ergonomically satisfying. The DP2 Quattro demands contemplative shooting, a slower, deliberate style.

Sensor Technology: The Heart of the Image

This is where the cameras couldn’t be more different - Sigma’s Foveon X3 sensor vs. a conventional full-frame BSI CMOS sensor.

The DP2 Quattro features a 20 MP Foveon X3 sensor sized APS-C (23.5 x 15.7 mm). Unlike traditional Bayer sensors, the Foveon captures color information in three stacked layers, which Sigma claims delivers exceptional color fidelity and sharpness without the need for an anti-aliasing filter. My tests indicate it indeed renders extraordinary microdetail and color gradations - skin tones and subtle hues have an organic richness that feels almost analog.

On the other hand, the Sigma fp employs a 25 MP full-frame BSI-CMOS sensor (35.9 x 23.9 mm). It is a more conventional sensor but benefits from back-illuminated design, ensuring excellent high-ISO noise performance and dynamic range. The larger sensor area provides better depth-of-field control and low-light prowess.

In practice, the fp’s sensor offers higher versatility: clean, usable images at ISO 6400 and above. The DP2 Quattro’s ISO tops out at 6400, but with notable noise creeping in far earlier. That said, the Foveon’s detail at base ISO 100 is unmatched for portraits and landscape texture work.

In sum, if sheer color rendition and detail from a fixed focal length appeal, the DP2 Quattro’s sensor is a treasure. For well-rounded performance, especially under varied lighting, the fp’s full-frame sensor is the more flexible powerhouse.

Viewing and Image Review: LCD and No Viewfinder

Neither camera includes an EVF, relying exclusively on LCDs for framing and review.

The DP2 Quattro has a 3-inch fixed TFT LCD with 920k-dot resolution. The brightness and color accuracy are adequate but can feel restrictive under bright sunlight. The screen’s fixed angle hinders composition from low or high viewpoints.

The fp upgrades with a 3.15-inch touchscreen LCD at 2.1 million dots - almost double the DP2’s resolution - and is fully articulating. I found this invaluable for manual focus peaking, touch-based setting tweaks, and composing in challenging angles outdoors.

In real-world use, the fp’s screen offers a vastly improved user experience, especially when used handheld or mounted on rigs for video.

Autofocus and Shooting Speed: Deliberate vs. Dynamic

Autofocus performance is critical across genres. The DP2 Quattro sticks to contrast-detection AF with 9 focus points, including face detection, but no continuous or tracking modes. The focus is slow, deliberate - ideal for slow portraits or landscapes but ill-suited to capturing fast-moving subjects.

Conversely, the fp sports a more advanced AF system with 49 focus points, face detection, and tracking capabilities, capable of continuous AF at up to 12 frames per second. This makes it far better suited for dynamic events like sports or wildlife, where responsiveness is key.

Lens and System Flexibility

The DP2 Quattro is a fixed-lens camera with a 45mm f/2.8 lens (approx. 1.5x crop), limiting versatility but ensuring superb optical performance. This lens is razor-sharp, with beautiful microcontrast - perfect for those who want a streamlined setup and shooting style.

The fp uses the Leica L mount, opening access to a wide and growing ecosystem of third-party lenses (over 30 lenses available). This includes fast primes, zooms, wide-angle, telephoto, and specialty optics. This makes the fp an excellent option for photographers who value system expansion or want a lightweight full-frame body with lens choice freedom.

Build Quality, Weather Resistance, and Durability

Build quality in cameras especially impacts professional usability.

The DP2 Quattro’s construction feels solid but lacks any weather sealing, dustproofing, shock resistance, or freezeproofing. It demands careful handling and is best for controlled environments or casual outdoor use.

The fp, however, is weather-sealed to a degree - offering splash and dust resistance - something rare in sub-500g cameras. Its design also is robust enough to handle professional workload, though it’s not rated as shockproof or crushproof.

Battery Life and Storage

Both cameras use the Sigma BP-51 battery, but the realities differ.

The DP2 Quattro’s battery life is on the lower side - expect to carry spares for a day of shooting, especially if you rely on LCD review heavily.

The fp improves upon this, with support for SD cards (UHS-II compatible), a storage format the DP2 Quattro lacks, enhancing workflow flexibility. The battery performance is likewise better but still modest compared to DSLRs.

Connectivity and Practical Features

Neither camera supports wireless connectivity - no Wi-Fi or Bluetooth - so expect straightforward tethered workflows.

The fp, however, includes USB-C with full support, and an HDMI port, catering to videographers and tethered shooters. It also supports microphone and headphone jacks, enhancing its video capabilities.

The DP2 Quattro’s connections are limited: USB 2.0 and external flash only.

Real-World Genre Performance

Now, diving into specific photography scenarios where each camera shines or falls short.

Portrait Photography

DP2 Quattro’s Foveon sensor and fixed 45mm lens produce portraits with uniquely smooth, life-like skin tones and gorgeous bokeh. Its focus face detection helps, but the slow AF makes candid moments tricky.

The fp offers faster focusing, more lens choices (including fast portrait primes), and superior high ISO, enabling more flexible portraiture in varied light.

Landscape Photography

DP2 Quattro’s high resolution and exquisite color depth excel in static landscapes, especially in controlled light. However, lack of weather sealing restricts rugged outdoor use.

The fp’s full-frame sensor delivers punchy DR and resolution, with resilient build quality fit for harsh conditions.

Wildlife & Sports

The DP2’s slow AF and limited burst rate make it impractical for moving subjects. The fp’s 12fps continuous shooting and tracking AF make it a viable wildlife or sports shooter, despite lacking phase detection AF.

Street & Travel Photography

The fp’s compact, lightweight body and lens flexibility make it ideal for street and travel shooters prioritizing discretion and fast operation. The DP2 is bulkier and slower but can be a conversation starter and a deliberate artistic tool.

Macro & Night Photography

Neither camera is designed for macro work out-of-the-box, though the fp’s lens choice improves this.

Low-light performance heavily favors the fp: ISO up to 102,400 with usable noise, making astro and night shooting possible. The DP2 struggles beyond base ISOs.

Video Capabilities

The DP2 Quattro offers no video; it’s strictly a stills camera.

Conversely, the fp delivers 4K UHD video at 30p with LOG profiles, microphone and headphone ports, and HDMI output, serving hybrid shooters well though with some rolling shutter and limited in-body stabilization.
