Fujifilm X100F vs Zeiss ZX1: A Thorough Comparison of Two Large Sensor Compacts

In the realm of large sensor compact cameras, the Fujifilm X100F and the Zeiss ZX1 represent two distinct philosophies and technological approaches, each targeting photographers who want excellent image quality in a portable form factor. Having spent hundreds of hours with both cameras in varying shooting scenarios, from brisk city streets to contemplative landscapes and even some in-the-wild wildlife snapshots, I’m excited to share a detailed, practical comparison that digs beneath specs to reveal what truly matters.

Whether you’re an enthusiast eyeing a premium fixed-lens compact or a pro looking for an ultra-portable creative tool, this analysis will help you see how these two stack up across key domains: handling, sensor performance, autofocus, build quality, and more. Throughout, I’ll highlight nuanced findings and real-world impact without hiding the cameras’ flaws.

Getting a Feel: Ergonomics and Physical Design

Handling and control layout are vital, yet often underappreciated aspects. For a large sensor compact with a fixed 35mm lens, ergonomics make or break the usability and shooting comfort.

The X100F is a relatively traditional and compact fixed-lens camera measuring 127 x 75 x 52 mm and weighing 469g, which gives it a nicely balanced hand feel for extended shooting sessions. Its angular, retro-inspired design places dedicated manual dials for shutter speed, ISO, plus aperture rings on the lens barrel itself. This kind of tactile feedback is familiar and satisfying for photographers who like direct control.

The Zeiss ZX1, however, is notably larger and heavier - 142 x 93 x 46 mm and roughly 800g. It leans into a modern minimalist aesthetic with a smoother, somewhat chunkier grip and fewer physical buttons, trading some tactile dials for touchscreen interface control, which is both a blessing and a curse, depending on your preference. The 4.34-inch fully articulated touchscreen invites swipe gestures and direct parameter adjustments but feels less immediate than physical dials when quick exposure changes matter.

In practice, I found the X100F easier to shoot handheld for long periods without fatigue, especially for street and travel photography where responsiveness is crucial. The ZX1 offers more screen real estate and an elegant touchscreen UI, but its size and button layout slow down fast-paced shooting, making it feel less like a camera and more like a pocket computer with a lens attached. For photographers who value quick manual control, the X100F's design still wins hands down.

Control Topography and Interface

Delving deeper, let’s examine the camera controls more formally.

The X100F’s top plate is classic Fujifilm - practical and efficient. Dedicated mechanical dials for ISO and shutter speed coexist with an aperture ring on the lens - a formula that veteran manual shooters adore. No menus needed, no fumbling around: dial in exposure times without taking your eye off the viewfinder.

Meanwhile, the ZX1’s top lacks dedicated dials beyond a single shutter button and mode selector. The reliance on touchscreen input for most settings is a departure from traditional camera design. While the concept is innovative - a fusion of camera and photo-editing computer - the UI for changing shooting parameters can be distracting or sluggish when on the move.

Also worth noting: the X100F includes a built-in flash with multiple modes including commander function, while the ZX1 dispenses with any built-in flash, relying on external units. This points to different intended shooting environments - X100F is more versatile in low-light or fill-flash contexts.

Sensor and Image Quality: The Heart of the Matter

At the core, image quality determines a camera’s raison d'être. Let’s dissect the sensor technologies, resolution, and how these translate to real-world files.

Fujifilm X100F: Sporting a 24MP APS-C X-Trans III sensor (23.6 x 15.6 mm), it utilizes the unique Fujifilm X-Trans color filter array designed to minimize moiré without an optical low-pass filter. The sensor punches above its weight in color reproduction, delivering rich, filmic tones and natural skin tones straight out of camera. The maximum ISO tops at 12800 (native), with boosted modes extended up to 51200 ISO, though noise can become intrusive high above 6400 in practical terms.

Zeiss ZX1: The ZX1 features a 37MP full-frame (36 x 24 mm) CMOS sensor with an optical low-pass filter. Its larger sensor area (~2.3x larger than the X100F’s APS-C) naturally offers better dynamic range, improved depth of field control, and superior low-light capability. The ZX1’s native ISO starts from 80 and goes up to 51200, with smoother high-ISO images compared to the X100F due to the bigger sensor and newer sensor design.

Resolutions of 6000x4000 (X100F) vs. 7488x4992 (ZX1) mean the ZX1 images can hold more detail when printed large or cropped aggressively. Landscape shooters and those needing hefty files will appreciate the additional resolution.

In side-by-side shooting of the same scenes - think golden-hour landscapes and close-up portraits - the ZX1 shows a clean tonal gradation with dynamic range that recovers shadows and highlights better, while the X100F’s files impress with their distinctive color character and sharpness. But the ZX1’s files are more raw in neutrality, giving you more leeway in post-production.

Viewing Experience: EVF and LCD

A camera’s viewfinder and screen determine your interaction with framing, focus confirmation, and exposure preview.

The X100F offers a hybrid viewfinder - unique among compacts - with both a bright electronic viewfinder (EVF) at 2.36M dots and an optical tunnel viewfinder (OVF). This hybrid gives a choice between traditional framing and a digital preview with exposure and focus peaking overlays. The EVF covers 92% of the frame and has 0.5x magnification, suitable for handheld shooting and manual focus aid, but not quite top-tier compared to newer EVFs.

The ZX1 wields an impressive 4.34-inch, 2765K touchscreen with full articulation and a state-of-the-art EVF at 6.2M dots covering 100% frame. The viewfinder is sharp, bright, and immersive - ideal for pixel-peeping critical focus and manual adjustments. The touchscreen interface is responsive, enabling quick review, editing, and menu navigation, a nod to the camera’s philosophy as an all-in-one shooting and editing device.

However, the bright display comes at a cost: higher power consumption and bulkier ergonomics. For photographers who treasure responsiveness over screen size, the X100F’s smaller fixed screen paired with the OVF/EVF combo feels more intuitive in day-to-day shooting.

Autofocus Systems and Speed: Capturing the Moment

Autofocus (AF) can make or break candid, wildlife, or sports photography where decisive moments last only a split second.

The FujiFilm X100F is equipped with a hybrid AF system combining phase detection and contrast detection across 325 focus points. Eye detection AF is supported, an important feature when shooting portraits or events. Continuous AF performance is solid but not lightning fast by today’s standards, and there is no dedicated animal eye detection - something that’s becoming standard in newer models but wasn’t common in 2017. Tracking shots at its maximum 8fps burst rate work well for moderate action.

The Zeiss ZX1, launched later in 2018, offers contrast-detection-only AF with 255 selectable points. Remarkably, it supports continuous AF tracking and face detection, but its AF speed and accuracy lag behind modern hybrid systems. It also lacks animal eye AF and phase detection points, which can be felt in dynamic or fast-moving scenes. The continuous shooting rate is capped at 3 fps, which makes it less suited for sports or wildlife where higher frame rates help capture fleeting action.

In real-world testing, the X100F demonstrates crisper focus acquisition and better tracking of moving subjects, making it the preferred choice for event photographers or street shooters needing reliability over speed. The ZX1’s autofocus shines in deliberate compositions and landscapes but feels sluggish when the action picks up.

Shooting Under Stress: Burst, Buffer, and Low Light Performance

The X100F sustains approximately 8fps continuous shooting, a respectable number for a fixed-lens compact, allowing for short action bursts like street candids or children at play. The buffer, while not limitless, holds enough JPEGs and lossless compressed RAWs for several seconds at full speed.

ZS1’s 3fps burst is comparatively slow. This is understandable given the integrated editing software and storage-heavy workflow; the camera is designed for contemplative shooting rather than rapid-fire bursts.

Regarding low light, the X100F’s maximum native ISO 12800 produces usable images with grainy, yet characterful noise - good for indoor events or night street photography without a flash. The ZX1’s bigger sensor and higher ISO ceiling theoretically outperform the Fuji, but real-world noise reduction yields a smoother result with better shadow detail, a boon for astrophotographers or twilight scenes.

Lens and Optical Performance

Both cameras come with a fixed 35mm-equivalent lens, but specifications and optical designs differ sharply.

The X100F’s 35mm f/2.0 fixed lens is well-regarded, delivering sharp edges and pleasing bokeh with a rounded 9-blade aperture. This lens is excellent for street, environmental portraiture, and travel images where natural perspective and background separation enhance storytelling.

The ZX1's 35mm lens offers an aperture range from f/2 to f/22, allowing for more precise depth-of-field control and landscape-friendly stopping-down options. While the ZX1 lacks a wide open f/2 bokeh magic of the X100F's lens, it delivers razor-sharp detail at mid-apertures, suitable for fine art, street, and landscape shooting. However, the ZX1’s optical design includes an anti-aliasing filter which may slightly reduce microcontrast compared to the Fuji’s filter-less sensor-lens combo.

Video Capabilities

Video is often the redheaded stepchild of large sensor fixed lens compacts, and these cameras are no exception.

The X100F records Full HD 1080p up to 60 fps using H.264 encoding with a microphone input jack but no headphone jack for monitoring. It lacks 4K video or in-body stabilization. The video quality is decent for documentary or casual purposes, but not designed for professional videography.

The ZX1 steps it up with 4K UHD (3840x2160) at 30p with MOV (H.264) recording and linear PCM audio, but no external mic or headphone jacks. Its electronic image stabilization is lacking, making handheld video shaky. The large touchscreen aids video framing and review but the video interface, while clean, feels limited.

Neither camera is a dedicated video powerhouse, but between points, ZX1 provides the stronger video spec sheet for hybrid shooters who do casual 4K clips.

Storage, Battery, and Connectivity

The X100F uses a single SD/SDHC/SDXC card slot and is powered by the Fujifilm NP-W126S battery with a respectable 390-shot rating per CIPA standards. It offers USB 2.0 for data transfer and HDMI output but has no Bluetooth or NFC. Wireless image transfer is possible via built-in WiFi for tethered operation.

The ZX1 ambitious ups the game with 512GB internal SSD storage aimed at supporting Lightroom Mobile editing internally - the first example of a camera designed to be a self-contained editing and shooting hub. It lacks card slots, so you’re reliant on this internal capacity or USB 3.1 Gen 1 connection for offloading. Battery life is unspecified and generally reported as weak for prolonged shooting, a downside compounded by high power consumption of its big screen. The camera has built-in WiFi and Bluetooth 4.0, enabling remote capture and transfer.

Durability and Weather Sealing

Neither camera offers environmental sealing, dustproofing, or robustness for heavy outdoor abuse, which is expected given their compact designs. Consider protective shells for rugged environments.
