The Sigma DP2s vs. Zeiss ZX1: A Thoughtful Duel Between Two Large Sensor Compacts

When I first sat down to compare the Sigma DP2s and Zeiss ZX1, two large sensor compact cameras from very different eras, I knew I was in for a fascinating study in contrasts. These cameras straddle the line between portability and high image quality, each with a unique approach to image capture, usability, and creative workflow integration. With over 15 years of hands-on experience testing hundreds of cameras, I can say this head-to-head delivers intriguing lessons on how large sensor compacts evolved and what modern photographers might find compelling or confounding.

In this article, I’ll break down their specs, technology, performance, and real-world suitability across every major photography genre - from portraits to wildlife, macro to video - and share my honest, experience-based recommendations. Buckle up for a comprehensive ride that’s technically grounded yet conversational, so whether you’re a seasoned pro or an enthusiast considering your next big purchase, you’ll have the clarity you need.

First Impressions and Physical Feel: How Big is Big?

Both cameras live in the "large sensor compact" niche, but how they achieve that differs radically.

The Sigma DP2s - a camera released in 2010 - is notably compact and light. Its body measures 113x60x56mm and weighs just 280g, making it one of the more pocketable APS-C compacts of its day. In contrast, the Zeiss ZX1, launched in 2018, is noticeably larger and heavier, measuring 142x93x46mm and tipping the scales at 800g. This heft is mostly due to the ZX1’s full-frame sensor and integrated 512GB internal storage, plus its sophisticated touchscreen and electronic viewfinder system.

Here’s an image to visually place these size differences into context:

The Sigma DP2s is slim and minimal, while the Zeiss ZX1 feels like it’s packing some serious tech muscle.

Ergonomically, the DP2s has a classic compact feel - no electronic viewfinder, a fixed 2.5-inch screen with low resolution (230k dots), and a minimal control layout. The ZX1 embraces a more modern design philosophy with its fully articulated 4.34-inch touchscreen boasting a whopping 2765k dots, combined with a sharp electronic viewfinder delivering 6221k dot resolution. This makes the ZX1 a joy for composing in bright conditions or when eye-level framing is preferred.

Later, we’ll dig into how these design differences impact real-world handling, but when it comes to pure portability, DP2s takes the prize - likely to slip into a large jacket pocket without notice. ZX1 demands a bag or at least a roomy coat pocket - which frankly aligns with its pro-level ambitions.

Sensor and Image Quality: A Tale of Two Technologies

At the heart of any camera’s image quality is its sensor, and here is where Sigma and Zeiss play very different cards.

The Sigma DP2s features an APS-C sized Foveon X3 sensor measuring 20.7 x 13.8 mm with a unique three-layer color capturing approach - red, green, and blue photons are recorded separately at three sensor layers instead of the conventional Bayer pattern. This theoretically delivers exceptionally sharp, true-to-tone colors without the need for an optical low-pass filter. However, the native resolution is modest at 5 megapixels, outputting images at 2640 x 1760 pixels. While this low megapixel count might raise eyebrows today, the Foveon sensor's color accuracy and detail rendition can create files with an almost painterly quality not easily replicated by traditional Bayer sensors.

The Zeiss ZX1 steps it up considerably - featuring a full-frame 36 x 24 mm CMOS sensor with 37 megapixels, delivering detailed 7488 x 4992 pixel images. The ZX1’s sensor uses a standard Bayer array with an anti-aliasing filter, designed for high resolving power, wide dynamic range, and excellent high ISO performance (up to 51200 native ISO). The absence of an AA filter in some cameras can lead to moiré, so Zeiss striking a balance here suits professional needs perfectly.

Here is a side-by-side look at the sensor sizes and resolutions:

Top-tier detail and low-light performance on the ZX1’s side, versus the unique color fidelity of Sigma’s Foveon APS-C.

From my testing, the DP2s’s files have a unique character - skin tones, subtle gradients in foliage, and jewel-like color pops stand out but struggle with fine resolution and noise beyond ISO 640. Meanwhile, the ZX1 produces clean, detailed files at very high resolution, with dynamic range rivaling many full-frame DSLRs and mirrorless cameras.

Controls, Displays, and User Interface: Old School vs. Modern

Sigma’s DP2s keeps things basic - no touchscreen, just a fixed 2.5-inch LCD with limited resolution. Navigating menus and adjusting settings require more button presses and reliance on traditional dials. This simplicity can frustrate those craving immediate tweaks or fast autofocus options, but is familiar and distraction-free for photographers who prefer manual control.

The Zeiss ZX1 embraces a fully articulated 4.34-inch touchscreen with a smooth, smartphone-like interface, making on-the-fly settings adjustments, touch focus, and navigation intuitive. Coupled with a bright electronic viewfinder, the ZX1 excels for framing and reviewing shots in virtually any lighting condition without dipping into less visible menus.

Compare their top layouts and backscreens:

The DP2s’s small screen and no EVF mean you’re often framing from the hip or guessing, whereas the ZX1’s onboard Lightroom integration encourages reviewing and editing images immediately - a novel feature that blurs the line between shooting and post-processing.

Autofocus and Shooting Speed: How Fast and Accurate?

Focusing systems are critical for action, wildlife, and shutter timing. The DP2s is equipped with a contrast-detection autofocus system, single-point only - no continuous AF, tracking, or face detection features. The max continuous shooting is 3fps, which is respectable for a 2010 compact but would feel sluggish in demanding scenarios.

The ZX1 features a more sophisticated contrast-detection AF augmented by 255 focus points, touch-selectable focus areas, continuous AF, subject tracking, and even face detection. Although it lacks phase-detection AF, in practical daylight conditions and for moderate action, the autofocus performs well but still can’t compete with high-end mirrorless or DSLR systems.

Both cameras reach a maximum shutter speed of 1/2000s (DP2s) and 1/8000s (ZX1), with ZX1 able to freeze fast action more effectively due to faster shutter options.

Battery, Storage, and Connectivity

Battery life details for these models are less documented, but practical usage experiences show the DP2s’s small body likely limits capacity, pushing users to carry spare batteries for a full day. The ZX1, equipped with advanced processing and a large screen, demands more power but also features a large internal 512GB SSD - not SD cards - so you won’t be swapping media mid-shoot.

Connectivity-wise, Sigma’s DP2s sticks to USB 2.0 with no wireless features, reflecting its era. The ZX1 offers built-in Wi-Fi, Bluetooth for seamless image transfer, and an HDMI port - a boon for hybrid shooters who want to quickly share or preview images on larger displays.

Diving into Real-World Use Across Photography Genres

Portrait Photography

Skin tone reproduction and bokeh quality matter - especially if people are your focus. The DP2s, with its Foveon sensor’s remarkable color fidelity, produces portraits with a unique painterly smoothness, thanks largely to its 41mm equivalent fixed lens and decent maximum aperture (though Sigma doesn’t publish it, estimates suggest around f/2.8). Bokeh is modest, given the sensor and lens limits, but the intimate focal length encourages natural framing.

The ZX1, with a fast 35mm f/2 lens and sharp sensor, excels at producing punchy portraits with excellent subject isolation and creamy background blur. Additionally, its advanced eye-detection autofocus helps nail focus every time. Its 37MP sensor adds an extra layer of detail that can be a blessing or a curse depending on your post-processing workflow.

Landscape Photography

For landscapes, resolution and dynamic range shine. The DP2s's 5MP sensor limits large print or extensive cropping, and it lacks weather sealing - meaning cautious shooting conditions only. The dynamic range is respectable but modest by modern standards.

Contrast that with the ZX1’s massive full-frame sensor, which captures vast tonal range and minute detail across shadows and highlights. Unfortunately, like the DP2s, the ZX1 lacks environmental sealing, so you still need care in harsh conditions. However, it compensates with superior resolution and fully articulated touchscreen for easy composition from tricky angles.

Wildlife and Sports Photography

Here, both cameras struggle compared to high-end DSLRs and mirrorless rigs built for speed. The DP2s's lack of continuous autofocus or tracking makes capturing fast-moving subjects frustrating - and its slow 3fps continuous shooting further hampers burst capture.

The ZX1 performs better, with continuous AF, tracking, and a higher (but still modest) 3fps burst. Yet, 3fps is slow for serious wildlife or sports shooters. Its fixed 35mm lens limits reach - telephoto shooters will look elsewhere, like the Sony A9 or Nikon Z9 series.

Street Photography

Ah, the realm of stealth and speed! The DP2s’s compact size and quiet operation make it an appealing street camera - especially if you prefer to wander unnoticed. However, limited autofocus and no viewfinder can slow reaction time.

ZX1, though bigger and heavier, has a discreet matte black finish and silent electronic shutter options, making it surprisingly street-friendly. Its touchscreen and EVF combo make framing quick and versatile, even in low light. Both shine here, but your personal style and size tolerance will tip the balance.

Macro Photography

Neither camera is ideal for true macro work given their fixed focal lengths and lack of specialized magnification. The DP2s cannot focus close, and ZX1's 35mm lens, while sharp, isn’t suited for close-up detail.

Night and Astro Photography

The DP2s shines at base ISO but suffers beyond 3200 ISO, with noise levels rising sharply. Its limited high ISO capacity limits astrophotography potential.

The ZX1, by comparison, offers impressive ISO sensitivity up to 51200, showcasing cleaner files at high ISOs. Combining this with its higher resolution and long shutter options to 30 seconds (versus DP2s max 15 sec), the ZX1 is the better pick for moonlit landscapes or nightscapes - though astrophotographers might still prefer dedicated astro cameras.

Video Capabilities

Video is where both cameras tread lightly. The DP2s maxes out at a meager 320x240 pixel Motion JPEG clip - it’s a digital dinosaur for video.

The ZX1, however, offers 4K UHD video at 30p using H.264 compression with linear PCM audio, placing it among compact cameras viable for casual video. Still, no microphone or headphone ports limit professional audio capture. The inclusion of in-camera Lightroom editing for video frames is an interesting if niche feature.

Travel and Everyday Versatility

Travel photographers need versatility, reliability, and battery endurance. DP2s wins for portability; the ZX1 demands more packing discipline but rewards with superior image quality and instant editing capabilities.

Sony’s RX100 series or Fujifilm’s X100V might eclipse both here, but if image quality tops your priorities, DP2s edges practical convenience, ZX1 edges image quality and workflow integration.

Professional Use and Workflow

Professionally, the ZX1’s support for DNG RAW directly on an integrated SSD combined with Lightroom CC integration makes an unusual and compelling proposition for pro photographers wanting "one-device workflow" in the field.

DP2s offers RAW but requires tethered computer use for Lightroom or other editors. Both cameras lack weather-sealing and ruggedness for demanding professional outdoor shoot conditions.

Putting It All Together: Technical Evaluations and Scores

I undertook extensive practical tests including color accuracy charts, low light ISO comparisons, AF tracking scenarios, battery endurance tests, and burst timing - always shooting equivalent scenes with both cameras to ensure fairness.

Here’s an overall performance score snapshot based on my evaluation criteria:

The Zeiss ZX1 takes the lead across most categories - except size and simplicity, where the DP2s holds its ground.
