Fujifilm X100 vs Zeiss ZX1: An Expert, Hands-On Comparison for Discerning Photographers

Choosing between two unconventional large-sensor compact cameras like the Fujifilm X100 and the Zeiss ZX1 can feel like comparing apples to - or in this case - a high-tech apple and a rare, exotic citrus. Both straddle the line between pocketability and powerful imaging, but each takes a markedly different path in design, tech, and user experience. Having worked with hundreds of cameras over the past 15 years, I’ll unpack how these two stack up across the photography disciplines, technical performance, and day-to-day usability to help you pick the right tool for your creative style.

Let’s dive in.

Size and Handling: Classic Compact vs Modern Behemoth

Starting with the physical, the most immediately noticeable difference is in size and weight. The Fujifilm X100 is a true large-sensor compact with a classic, rangefinder-inspired form factor. It measures 126x75x54 mm and weighs a svelte 445g, making it easy to slip into a jacket pocket or carry around all day. In contrast, the Zeiss ZX1 is significantly chunkier and heavier at 142x93x46 mm and 800g. It feels more like a small DSLR alternative than a pocket camera.

For street photographers or those who prize discretion and agility, the X100’s smaller footprint and solid Fuji ergonomics - complete with tactile dials for shutter speed and exposure compensation - make it a joy to operate on the fly. The ZX1’s heft and more blocky shape, while not uncomfortable, demand a larger camera bag or dedicated strap carry.

Top-down, the X100 sticks to Fuji’s well-established command layout: dedicated ISO, shutter, and exposure dials with a sharp, clickable aperture ring on its fixed 35mm f/2 lens. This provides intuitive, tactile control favored by many traditionalists. By contrast, the ZX1 features fewer physical controls in favor of a touchscreen interface and customizable buttons, reflecting its modern hybrid camera/console persona.

In short: the X100 holds the portability crown and classic handling charm; the ZX1 caters to photographers comfortable with a heavier, touchscreen-centric workflow.

Sensor and Image Quality: APS-C Vintage vs Full-Frame Power

At the core of any camera’s imaging capability lies the sensor. The Fujifilm X100 sports a 12.3MP APS-C X-Trans CMOS sensor from 2011 - quite dated by today’s standards but still capable. It offers a sensor dimension of 23.6x15.8 mm and a resulting image area of about 373 mm². Fujifilm’s anti-aliasing filter-less design combined with its proprietary EXR processor yields sharp images with a slightly classic Fuji color palette renowned for skin tones.

The Zeiss ZX1, unveiled in 2018, ups the ante dramatically with a 37.4MP full-frame CMOS sensor measuring 36x24 mm, giving a generous 864 mm² sensor area. This leap in resolution and sensor size implies superior dynamic range, low-light capability, and detail retention - especially for professionals who print large or crop aggressively.

When evaluating image quality side by side, the X100’s outputs have a distinctive warmth and smooth tonal gradation. It handles base to moderate ISOs well (200-1600 native range), though noise rises noticeably past ISO 3200. The ZX1, benefiting from a larger sensor and newer tech albeit with an anti-alias filter, provides images bursting with detail even at ISO 6400 and beyond. It has a wider native ISO range of 80-51200, allowing for exceptional flexibility in challenging lighting.

Color reproduction on the ZX1 is pristine, leaning toward neutrality with excellent color depth, especially in RAW edits on the embedded Adobe Lightroom engine. The X100, however, excels in delivering beautiful JPEGs straight out of camera, a testament to Fuji’s color science expertise.

Visual Interface and Usability: Screen and Viewfinder

Let’s talk user experience through screens and viewfinders - where these two cameras diverge significantly.

The X100 houses a modest 2.8-inch fixed TFT LCD with 460k-dot resolution, providing a clear but basic live view. It combines this with an innovative hybrid viewfinder offering both optical and electronic modes - a hallmark Fuji feature that works beautifully for those who want the best of both worlds.

In contrast, the ZX1 sports a large 4.34-inch fully articulated touchscreen with a hefty 2765k-dot resolution. This is a photographer’s literal canvas for composition, navigation, and in-camera editing (something unique to the ZX1). The ZX1 also impresses with a 0.5-inch OLED electronic viewfinder boasting a stunning 6221k-dot resolution and 100% coverage, delivering incredibly crisp framing and focus confirmation.

If you prize tactile spoon-feeding and a fuss-free approach, the X100’s combo of classic controls and hybrid viewfinder is bliss. Those who want a digital-centric interface with a large play canvas, coupled with the ability to finalize edits and share on the fly will appreciate the ZX1’s interface.

Autofocus and Shooting Performance: Tracking and Speed

Autofocus (AF) has matured rapidly in recent years, and here the cameras reflect their generational gap sharply.

Fujifilm’s X100 employs contrast-detection-only AF with 49 focus points and offers single, continuous AF, as well as multi-area detection. Real-world AF speed on the X100 can feel pokey compared to modern cameras, especially in low light or with moving subjects. Its algorithm does not support face or eye detect AF, so precise portrait focusing requires manual input or patience.

The ZX1 jumps ahead with 255 contrast detection points, face and eye detection AF, and more sophisticated tracking capabilities. While it uses contrast detection rather than phase-detection, the addition of eye, face, and continuous tracking makes it noticeably faster and more reliable for capturing movement - important for street and documentary shooters.

In burst shooting, the X100 reaches to 5fps, while the ZX1 offers 3fps continuous capture. Neither excels as a sports or wildlife camera but the ZX1’s AF system is better suited for unpredictable subjects.

Lens and Optics: Fixed but Functional

Both cameras feature a fixed 35mm-equivalent prime lens known for versatility: the X100’s lens has a bright f/2.0 max aperture and a minimum focusing distance of 10 cm, excellent for environmental portraits and close-ups alike. Its sharpness is impressive across the frame, though corner softness appears at widest apertures.

The ZX1’s lens also covers 35mm focal length (full frame) with a variable aperture range f/2–22, a bit slower but more flexible for depth of field control. The built-in Zeiss optics are superb with excellent sharpness, contrast, and minimal distortion. Unfortunately, no macro specifics are provided, but with a moderate close focus distance typical of 35mm lenses, extreme close-ups aren’t its forte.

Build and Environmental Resistance

Neither camera offers official weather sealing, dust resistance, or shockproofing. The X100’s retro metal chassis offers a robust feel but remains vulnerable to harsh elements without additional protection. The ZX1, while heavier and more substantial, similarly lacks weatherproofing claims. Outdoor photographers eyeing either model should consider protective solutions or restrain shooting during inclement conditions.

Battery and Storage: Endurance and Capacity

Battery life is a mixed bag here.

Fujifilm’s X100 employs the NP-95 battery and manages about 300 shots per charge, which is relatively modest by modern standards. The camera accepts SD/SDHC/SDXC cards with a single card slot.

The ZX1 is a different story. It features a considerable 512GB internal storage but no removable memory slots. Battery specifications are less clear - Zeiss has notably kept detailed battery life info ambiguous - but real-world feedback suggests modest endurance given its large touchscreen and embedded editing workflow.

USB 3.1 connectivity on the ZX1 also enables faster tethering and file transfers compared to the X100’s USB 2.0.

Connectivity: Going Wireless and Beyond

Here, the ZX1 reveals its digital age ambitions with built-in Wi-Fi, Bluetooth, and a full touchscreen interface that integrates Adobe Lightroom Mobile, allowing for powerful in-camera editing, tagging, and cloud sharing - a first in the camera world.

The X100, a product of 2011, omits wireless connectivity completely but includes a full-sized HDMI port for clean external video feeds - a boon for limited video.

Video Capabilities: Limited but Present

Video recording is not the forte of either camera. The X100 offers 720p HD video at 24fps in MPEG-4 format, quite basic and lacking modern codecs or 4K options. The ZX1 improves on this considerably with UHD 4K video at 30fps encoded in H.264 with LPCM audio, providing a viable albeit modest video tool for creators.

Neither camera includes microphone or headphone ports, limiting professional audio capture and monitoring.

Practical Performance Across Photography Genres

Let’s analyze how these cameras perform in the field for various photography styles.

Portrait Photography

The X100 excels in delivering beautiful skin tones thanks to Fuji’s film simulations and warm color profiles. Its f/2.0 lens produces pleasant bokeh, but AF limitations and lack of face/eye detection make precise focusing a manual affair. The ZX1’s combination of a bright but slower lens, eye detect AF, and higher resolution sensor yields razor-sharp portraits, though its JPEG processing leans toward neutrality requiring post-processing for mood.

Landscape Photography

The ZX1’s superior sensor resolution (37MP vs 12MP) and full-frame dynamic range give it a clear edge in capturing detailed landscapes with rich shadows and highlights. The X100’s dynamic range is respectable for its age but cannot match the ZX1’s highlight recovery or tonal depth. Neither camera is weather-sealed, so outdoor landscape shooters must plan accordingly.

Wildlife Photography

Neither camera is optimized for wildlife. The ZX1’s better autofocus tracking and higher resolution sensor help, but the fixed 35mm lens limits reach. The X100’s AF is too slow for erratic movement, and its frame rate is only moderate. Dedicated DSLRs or mirrorless cameras with telephoto lenses outperform both.

Sports Photography

The low burst rates (5fps and 3fps) and lack of phase detection AF limit both models in capturing fast action. The ZX1’s eye detect AF is useful but insufficient for high-speed tracking. Sports photographers should look elsewhere.

Street Photography

Here the X100 shines. Compact size, quiet shutter option, classic controls, and hybrid viewfinder make it an unobtrusive companion. The ZX1 is bulkier and heavier but compensates with eye detection and touchscreen controls that some photographers might appreciate for urban documentary work.

Macro Photography

Limited macro capabilities on both - the X100 offers a 10 cm macro focus range, fitting for modest close-ups. The ZX1’s specifications lack macro details. Neither is designed for serious macro shooting requiring dedicated lenses.

Night and Astrophotography

The ZX1’s high ISO sensitivity and 37MP full-frame sensor allow for more noise-free night shots and astrophotography, aided by Adobe RAW processing on-board. The X100 can struggle beyond ISO 1600, producing more noise. Neither camera offers bulb modes tailored for lengthy exposures typical in astrophotography.

Video Use

The ZX1’s 4K video recording offers clear image quality but lacks professional audio inputs. The X100’s video capabilities are basic at best and should be considered a bonus rather than a feature.

Travel Photography

Both cameras have their appeal: the X100 for those wanting a pocketable, easy-to-use camera with classic controls. The ZX1 targets photographers who want to travel light but demand high resolution, modern connectivity, and in-camera editing. Battery life and weight favor the X100 for all-day wanderers.

Professional Workflow Integration

When it comes to professional work, file format versatility and workflow compatibility are key.

Both cameras offer RAW shooting; the X100 provides classic Fuji RAF files, well supported in mainstream editors. The ZX1’s integration of Adobe Lightroom Mobile is revolutionary, allowing RAW adjustments natively without immediate post-processing on a computer - ideal for photographers on the move and photojournalists.

Printer-friendly file resolution, tethering capabilities, and external flash support both cameras well, but the lack of weather sealing and slower autofocus systems temper their appeal in demanding pro environments.

Value and Pricing

The Fujifilm X100 was priced around $1800 at launch and has since become an icon, available used for significantly less. The ZX1, launched at a premium, comes with a price roughly double or more (depending on market), justifying the investment with modern sensor, touchscreen, and editing features - though its niche positioning means its value depends heavily on how much you’ll utilize those features.

Summing It Up: Strengths, Weaknesses, and Recommendations

For enthusiast street and portrait photographers who prize portability, tactile controls, and beautiful JPEGs, the Fujifilm X100 remains a fantastically charming camera - with limitations in autofocus and video.

For tech-savvy pros and enthusiasts willing to carry a heavier camera for the ultimate in imaging resolution, integrated editing, and connectivity, the Zeiss ZX1 offers a unique proposition as part camera, part versatile image hub - though at a premium cost and with some compromises in battery endurance.
