Sigma DP1x vs Zeiss ZX1

Sigma DP1x vs Zeiss ZX1: An In-Depth Comparison of Two Unique Large Sensor Compacts

Over my 15+ years testing digital cameras, I’ve encountered countless designs aiming to balance quality and portability. Few cameras have intrigued me quite like the Sigma DP1x and the Zeiss ZX1 - two large sensor compacts released nearly a decade apart, with distinctly different philosophies. As someone who’s evaluated hundreds of cameras for everything from studio portraiture to wildlife tracking, rising above marketing specs to reveal practical realities is second nature. Today, I’ll walk you through a comprehensive comparison of these two models, not just by their tech specs but with insights drawn from extensive hands-on testing, so you can decide which suits your photographic vision and workflow.

First Impressions and Handling: Ergonomics & Design Personality

Before we dive deep into specs and performance, I find it critical to discuss the handling experience since anyone who’s spent hours shooting understands how ergonomics influence creativity.

The Sigma DP1x is compact, minimalist, and distinctly retro. Its fixed 28mm equivalent F4 lens and modest 2.5-inch low-res LCD reflect its 2010 vintage. The body is surprisingly petite. Measuring just 113 x 60 x 50 mm and weighing a featherlight 250g, it almost disappears in hand or pocket. While small, it does not evoke disposable toy-like qualities - the build is sturdy with a satisfying heft for its size, but it’s clearly not designed for comfortable extended shooting sessions or fast operation.

Conversely, Zeiss’s ZX1 feels like a different beast altogether. At 142 x 93 x 46 mm and weighing 800g, it is more akin to a serious tool packed with contemporary tech. Its larger form factor makes it ergonomically significant for gripping securely, particularly for longer shoots. The fully articulating 4.34-inch high-res touchscreen, combined with an electronic viewfinder, indexes it firmly in the modern high-end compact segment focused on usability.

Handling-wise, the DP1x demands deliberate, slower shooting, favoring contemplative photographers. The ZX1 invites direct tactile engagement, with customizable buttons and a responsive interface much closer to mirrorless cameras I've tested.

Control Layout and User Interface: Traditional Meets Tomorrow

Tactile feedback and intuitiveness in controls can make or break the shooting experience. The DP1x’s top layout is sparse - think minimal buttons, no dials for ISO or exposure compensation, and a small screen for feedback. It relies heavily on manual focus rings and menus that feel dated by today’s standards. This simplicity, however, might appeal if you prefer minimal distractions or exclusively manual control.

The ZX1’s top surface is busier with buttons placed logically for speedy access to key functions, including exposure modes and focus. Meanwhile, its fully articulated touchscreen provides an intuitive, smartphone-like UI experience I always appreciate when reviewing newer cameras.

Having shot for hours with both, I note that the Sigma’s lack of versatility slows down spontaneous, dynamic shooting. Zeiss ZX1 feels more modern and fluid - it’s a camera you can quickly tweak on-the-fly, vital in fast-changing environments such as street or event photography.

Sensor and Image Quality: The Heart of the Matter

Now to the core: image quality. The DP1x houses Sigma’s signature Foveon X3 APS-C sensor measuring 20.7 x 13.8 mm with a unique approach capturing color information in three layers. It’s an alluring proposition for still life and portraiture, rendering colors with painterly depth, delivering 5MP effective resolution (2640x1760), and a native ISO range constrained to 100–3200.

The ZX1 sports a contemporary 37MP full-frame Bayer sensor (36 x 24 mm), enabling much higher resolution (7488x4992 pixels), extended dynamic range, and exceptional high ISO performance up to ISO 51200. This sensor offers lengthier reach across genres that demand detail retention and flexibility.

Technically, Foveon produces stunning color fidelity and subtle gradations at base ISO, with quick fall off in noise beyond 800 ISO, limiting its low-light plasticity. Our lab and field measurements confirm the ZX1’s sensor is vastly superior for wide ISO ranges, dynamic range, and detail retention - clear benefits for landscape and professional use.

Screen and Viewfinder: Visual Feedback & Framing Tools

On the DP1x, the fixed 2.5-inch LCD with a mere 230k-dot resolution feels cramped and dim by today’s standards. There’s no viewfinder, forcing reliance on the LCD which can be challenging in bright sunlight.

Meanwhile, the ZX1 boasts a 4.34-inch fully articulating touchscreen with an incredible 2765k-dot resolution, coupled with a 6221k-dot electronic viewfinder. As someone who tests everything from entry-level compacts to cine cameras, I understand how crucial clear visualization is for precise focus and composition, especially under tricky lighting.

In real-world use, the ZX1’s articulate screen also permits creative shooting angles and selfie convenience (though not marketed as selfie-friendly). This thorough feedback ecosystem facilitates confident framing in diverse shooting conditions.

Autofocus and Focusing Experience

A significant factor for many photographers is autofocus reliability and speed. The DP1x relies on contrast detection AF without phase detection or face/eye tracking. It has no dedicated AF points and is limited to single AF mode, requiring patience to nail focus.

The ZX1 ups the ante with a sophisticated 255-point AF system incorporating contrast detection with face detection and continuous tracking. In prior wildlife and street tests, I found its tracking responsive with minimal hunting.

For macro or portrait photographers chasing sharp eyes and smooth bokeh backgrounds with precision, the ZX1 offers superior focus flexibility thanks to touch AF+tracking, while the DP1x requires focus peaking and manual nudging.

Lens and Focal Length Considerations

Both cameras feature fixed lenses that define their core utility. The DP1x has a 28 mm F4 prime, roughly equivalent to 43–44 mm on 35mm format due to its 1.7x crop factor. The lens is sharp and crisp but limited in aperture and zoom flexibility, hailing as a “set it and forget it” tool aimed at wide-angle street, documentary, and environmental landscape.

The ZX1’s 35 mm F2 lens is a classic workhorse focal length, perfect for a wide spectrum from street to environmental portraits. With an aperture range down to F22, it provides greater exposure control and more attractive shallow depth-of-field potential.

From my experience, the faster Zeiss lens on the ZX1 offers more creative latitude, particularly in low light and subject separation, while the DP1x’s lens might struggle for isolation but rewards with simplicity and compactness.

Continuous Shooting and Burst Performance

Neither camera targets sports shooters, but for awareness: the DP1x lacks continuous shooting capabilities entirely, making it unsuitable for action photography.

The ZX1 offers a modest 3 fps burst rate; while not lightning fast compared to professional mirrorless gear, it’s functional for casual movement capture and better suited to evolving scenes than the DP1x.

Build Quality and Durability: Weather Gear?

Neither camera offers weather sealing, dustproofing, or ruggedization overtly. The DP1x is compact but modestly built, with no specialized environmental protections, meaning caution is warranted in inclement weather.

The ZX1’s larger body provides a more substantial grip and slightly more robust feel, yet still lacks official weather sealing. I would exercise care outdoors, especially given its premium components and internal SSD storage.

Battery Life and Storage Solutions

Battery life details for both are limited, but the DP1x’s small size and age hint at shorter endurance, compounded by older chipsets and LCD tech.

More remarkably, the ZX1 has a 512GB internal SSD, a rare approach among cameras that reduces the risk of silent card corruption and improves speed but limits swap-ability. It supports a single SD card slot for backup or file import.

Connectivity on the ZX1 includes USB 3.1, Bluetooth, and HDMI, enabling faster file transfer and on-the-spot sharing, crucial for modern workflows. The DP1x has only USB 1.0, a painfully slow option in today’s context.

Real-World Photography Across Genres

Having outlined the mechanical and technical aspects, let’s talk about usability across photographic disciplines.

Portrait Photography

The DP1x’s unique Foveon sensor renders skin tones with a painterly, subtly organic feel. The lens’s F4 max aperture limits creamy bokeh but gives sharpness across the frame. Lack of autofocus aids limits ease of obtaining sharp eyes.

The ZX1’s larger sensor, higher resolution, and F2 aperture create beautiful shallow depth-of-field and excellent eye-detection autofocus, making portraits sharper and more natural. For professional portraitists, its color rendition and detail offer a modern advantage.

Landscape Photography

DP1x provides respectable detail at base ISO but 5MP resolution constrains print or crop size. Dynamic range is limited by sensor design but color fidelity shines. Its compact body’s lightweight is a plus for hikers who prioritize portability.

ZX1’s full-frame sensor unlocks vastly superior resolution and dynamic range, critical for landscapes with extreme lights and shadows. Though heavier, the larger battery and articulating screen aid long exposures and framing.

Wildlife and Sports Photography

Neither camera is well suited to wildlife or sports given slow burst rates and fixed lenses. The ZX1’s 3 fps and advanced AF is closer to usability here; the DP1x is hardly viable for these genres.

Street Photography

DP1x’s compact size, quiet operation, and subtle lens make it discreet for street shoots, especially in well-lit conditions. However, its slow operation may hinder fast-moving scenes.

ZX1’s larger size and louder operation make it less discreet, but superb autofocus and lens speed help capture fleeting moments with clarity.

Macro Photography

Both lack macro lens support; DP1x has no macro range spec, ZX1 has none either. Neither is ideal here.

Night and Astro Photography

DP1x’s ISO ceiling of 3200 and sensor noise limit astrophotography; no image stabilization hinders handheld low-light work.

ZX1’s high ISO up to 51200 and full-frame sensor are better suited for night shooting, though the lack of stabilization remains a challenge.

Video Capabilities

DP1x video maxes out at 320x240 QVGA resolution, essentially useless by today’s standards.

ZX1 shoots UHD 4K video at 30p with modern compression and audio, unfurling creative opportunities beyond stills.

Travel Photography

DP1x’s compact form and simple operation suit light travel kits and street documentation but compromised by slow responsiveness.

ZX1’s versatility, power, and connectivity make it a robust travel all-in-one, though its bulk and weight increase hauling load.
