If you’re on the hunt for a new mirrorless camera, it’s critical to not just skim specs but immerse yourself in how these tools perform in your real-world photographic adventures.

In this hands-on comparison, I’ll take you through every angle: sensor prowess, autofocus wizardry, ergonomics, video chops, and suitability across photography genres. Whether you’re an enthusiast looking for your dream starter mirrorless or a pro who demands bulletproof reliability and stellar image quality, I’ll help you make the best call without any smoke and mirrors.

Let’s dive in.

Getting Acquainted: Size, Feel, and Controls

Before pixel peeping, the first tactile experience with a camera sets the tone for repeat use.

Here’s where the Fujifilm X-S10 shows off its nimble, entry-level mirrorless nature. Weighing in at a featherlight 465g, it fits comfortably in most hands - even if you have dainty digits or like to travel light. The Fuji’s modest footprint (126 x 85 x 65 mm) means it’s not going to weigh down a day-long hike or get in the way when you’re shooting street scenes on the go.

On the flip side, the Leica SL2-S commands attention at 931g and measuring 146 x 107 x 83 mm. This isn’t lightweight or compact territory; it’s a serious grip for serious shooters. Leica’s build quality is something you feel with every hold – dense, machined aluminum body, and the confidence that it’s built to last and to withstand pro-level abuse.

Controls reflect the personalities of these cameras. The Fuji X-S10, despite its entry-level tag, surprisingly offers a rich SLR-style control layout, with a raised grip and easily assignable dials. However, it opts out of top-plate LCDs or illuminated buttons, relying heavily on a fully articulating touchscreen (more on that soon) to navigate settings.

The SL2-S, however, is the embodiment of “pro club for thumbs.” Dual SD card slots (UHS-II in slot 1), a robust top LCD, and a host of customizable buttons delineate it as a tool built for workflow efficiency. For those shooting tethered or in fast-paced professional scenarios, these subtle ergonomic advantages compound into smoother days on set.

The Heart: Sensor Tech and Image Quality

Real-world image quality is a non-negotiable, and here the divide between APS-C and full-frame plays a starring role.

The Fujifilm X-S10 employs a 26MP APS-C BSI-CMOS sensor (23.5x15.6 mm), which delivers a solid 6240 x 4160 pixel resolution. This sensor punches well above its weight for mid-tier cameras, offering excellent sharpness, surprisingly vibrant studio-grade color rendition, and Fuji’s signature film simulations - drawing on decades of analog experimentation.

Leica’s SL2-S flips the script with a 24MP full-frame CMOS sensor (36x24 mm). Despite a nominally lower pixel count than some competitors, the larger sensor area enables superior dynamic range and noise control, particularly at higher ISOs (native max ISO 50,000 vs. Fuji’s 12,800). In my tests shooting high-contrast landscapes and dimly lit interiors, the SL2-S consistently yielded cleaner shadows and a more forgiving highlight roll-off.

The APS-C sensor in the Fuji does limit shallow depth-of-field extremes compared to Leica’s full-frame, especially for portrait enthusiasts chasing creamy bokeh and “pop.” But with Fuji’s extensive X-mount lens lineup (54 lenses and counting), you can still achieve pleasing subject isolation, especially with their fast primes.

Peeking Through the Eyepiece: Viewfinders and Screens

In scrappy street photography or intense studio shoots, the interface between your eye and the camera matters deeply.

Fujifilm outfits the X-S10 with a 3-inch, fully articulated, 1040k-dot touchscreen, perfect for vlogging, product photography, or awkward angles. The flip-and-twist screen is a major plus for content creators and solo shooters. The electronic viewfinder (EVF) is a 2.36MP OLED with 0.62x magnification - decent enough but somewhat faint in harsh daylight or intricate manual focusing scenarios.

Leica’s SL2-S, meanwhile, equips a fixed 3.2-inch display with a superior 2.1 million-dot resolution. While you sacrifice articulation, the screen quality is noticeably brighter and sharper, complemented by an EVF that is jaw-dropping: 5.76 million dots and 0.78x magnification. The experience is akin to looking through a glass window rather than an electronic proxy, giving critical focus and composition a tactile confidence.

For video shooters, both touchscreens are responsive - but Leica’s lack of flip-out limits front-facing self-recording.

Autofocus Systems: Tracking, Speed, and Precision

Autofocus can make or break your shot, especially in wildlife or sports where split-second performance is demanded.

The Fujifilm X-S10 features a hybrid autofocus with 425 points (phase-detect plus contrast detection). It has dependable face detection and eye AF that works reliably even in moderately low light. The slightly smaller sensor and APS-C nature help by making depth of field more forgiving.

During my outdoor wildlife sessions, the Fuji tracked subjects well but occasionally hesitated with erratically moving birds or under dense foliage, where its contrast-detection component struggled.

Leica’s SL2-S deploys 225 AF points, relying solely on contrast detection AF rather than phase detection - a deliberate design choice. Counterintuitive at first, this seems to prioritize accuracy over ultra-fast performance. In practice, it nails precise focusing in static or predictable subjects such as portraits, landscapes, or carefully composed scenes. However, in high-action sports or fast-moving wildlife, the SL2-S can lag behind high-end phase-detection shooters in sustained tracking.

Both cameras support touch-to-focus on their screens and offer eye and face detection, but only the Fuji’s AF system supports animal eye AF (currently absent on both). Fuji has a slight edge in autofocus versatility, but Leica’s system rewards those who value precision over speed.

Burst, Buffer, and Shutter Reliability

If you’re shooting fast-paced action - say basketball or wildlife - you want a camera that can keep up without choking on files.

Both cameras list a max continuous shooting speed of 20 frames per second. But that’s only part of the story.

The Fujifilm X-S10’s buffer and SD card interface (single UHS-I slot) introduce some limitations under darker compressed RAW shooting. After approximately 30 frames, the buffer clears, causing brief breaks.

The Leica SL2-S really shines here, thanks to its dual SD card slots and UHS-II in the first slot, paired with a robust processor. It can sustain long bursts and multi-frame captures without hiccups, making it closer to pro-level rapid-fire consistency.

That said, I found both shutter systems mechanically reliable and surprisingly quiet (Fuji supports electronic shutter up to 1/32000 sec). Leica also provides a max mechanical shutter speed up to 1/8000 second, great for shooting wide-open in bright daylight.

Video Capabilities: A Content Creator’s Perspective

Video is no longer a luxury feature - both of these mirrorless cameras cater to it seriously but with distinct approaches.

The Fuji X-S10 offers 4K UHD video recording up to 30p at 200 Mbps in MOV format with H.264 compression and Linear PCM audio. The fully articulated touchscreen supports selfie vloggers and creative framing. In-body Image Stabilization (IBIS) works impressively for handheld video, especially for run-and-gun shooters.

The Leica SL2-S raises the bar with more pro-friendly specs: 4K DCI (4096 x 2160) recording at up to 60p and ultra-high bitrate 400 Mbps at 24-30 fps, supporting slow motion in 1080p up to 120 fps, plus headphone and microphone ports for monitoring and clean audio capture. The IBIS here is sensor-based with five-axis stabilization, providing rock-solid footage, even with heavier lenses.

If video is a significant part of your workflow - whether documentary filmmaking or hybrid content creation - the SL2-S currently pulls ahead in specs and prosumer features, albeit at a far higher price.

Lenses and Ecosystem: Investing in Glass

You can have the most sophisticated camera, but without lenses that suit your style, it’s just a fancy brick.

The Fujifilm X-S10 uses the Fujifilm X mount, which boasts an extensive, growing selection of 54 native lenses ranging from affordable primes like the 23mm f/2 to excellent zooms and specialized lenses for macros and wider angles. Fuji’s reputation for premium optics at accessible prices allows entry-level buyers to build solid lens kits without breaking the bank.

Leica’s SL2-S uses the Leica L-mount, supporting 36 lenses natively. Though fewer in number, this line is built to legendary Leica standards, with exceptional build quality, stunning optics, and great reliability. Another bonus: Leica’s alliance with Panasonic and Sigma under the L-mount alliance means third-party choices and competitive options are steadily growing.

Lens investment matters hugely. The Fuji ecosystem is terrific for discerning beginners and budget photographers, whereas Leica caters to those prioritizing craftsmanship, durability, and ultimate image rendition.

Durability and Weather Resistance: Built for the Real World?

Shooting outdoor landscapes or commercial jobs demands cameras that won’t quit under rain, dust, or temperature swings.

The Fuji X-S10 offers no official weather sealing - a worthwhile caveat for hiking in drizzle or dusty environments. Its lightweight build and plastic-heavy parts make it vulnerable to rough handling.

Leica’s SL2-S is fully weather-sealed against dust and moisture. Its robust metal body and sealed internal components are ready for professional outdoor use, surviving freezing conditions and rainstorms with aplomb. I’ve personally pushed it on mountain shoots and it returned without a scratch.

Battery Life and Storage: Powering Your Day

Nothing kills an inspired shooting session faster than a dead battery or filling the memory card too early.

The Fujifilm X-S10’s battery life rates approximately 325 shots per charge, which is respectable for its class but might leave you scouting for extra packs on longer expeditions. With a single UHS-I slot, always have ample SD cards on hand.

Leica’s SL2-S significantly boosts battery life to about 510 shots per charge, and the dual UHS-II slots not only speed up write times but also provide redundant backups - a must-have for professional workflows where data loss means costly reshoots.
