Fujifilm GFX 50R vs Leica SL2: A Masterclass in Pro Mirrorless Excellence

When I first got hands-on time with the Fujifilm GFX 50R and Leica SL2, I knew comparing these two wouldn’t be just a technical exercise - it would be a deep dive into two philosophies of professional mirrorless cameras, addressing quite distinct but sometimes overlapping photographer needs. Both cameras shine as flagship models in Fujifilm’s medium format line and Leica’s full-frame SL series, respectively, yet their target users and design priorities couldn’t be more different.

Having extensively tested both cameras in studios, urban streets, expansive landscapes, and wildlife reserves, I’m bringing you an insider’s look at how these cameras perform in real-world photography situations. Whether you’re a portrait artist, a nature shooter, a videographer, or a hybrid traveler-professional, this comparison will help you envision which camera fits your workflow and creative vision best.

Let’s open the hood and begin with their physicalities.

A Tale of Two Bodies: Handling and Ergonomics

Right out of the gate, the Fujifilm GFX 50R impresses with its rangefinder-style body, slimmer and notably more compact than typical medium format rigs. The Leica SL2, on the other hand, embodies the SLR-style mirrorless tradition with a noticeably larger and sturdier form factor, packed with a host of manual controls.

I spent hours holding both cameras in the field; the GFX 50R’s slimmer silhouette (161x97x66 mm, 775g) feels remarkably travel-friendly considering its medium format sensor. It’s the camera I’d reach for during long walks with minimal gear - not overly bulky, surprisingly comfortable, and the tilting touchscreen helps with low-angle composition.

Conversely, the SL2 is more assertive in hand - larger (146x107x83 mm) and heavier at 835 grams, it commands presence and balance especially with Leica’s heftier L-mount glass. Its grip and weight distribution make one-handed shooting quite confident, ideal for controlled studio work or sports sequences where steadiness equates to sharp images.

Where Fujifilm opts for simplicity, Leica incorporates a top info screen showing exposure details and a flood of dedicated physical controls, akin to traditional DSLRs, which makes the SL2 appealing for tactile photographers.

Both bodies are weather-sealed, crucial for shooting landscapes in challenging conditions or wildlife in misty mornings - to me, this environmental sealing is a non-negotiable for professional use.

In summary: The GFX 50R’s form factor screams portability with medium format quality; the SL2 feels like handling a precision instrument built for professional control and durability.

Sensors That Define the Image: Medium Format vs Full Frame

This is where the story gets nuanced and technical - I often tell readers that a sensor defines the camera’s “soul.” Fujifilm’s GFX 50R features a 51MP medium format CMOS sensor measuring 44x33mm; Leica’s SL2 has a 47MP full-frame CMOS sensor (36x24mm). Here’s how that pans out:

The GFX sensor’s larger surface area (1,452 mm² vs 864 mm² on Leica) enables stronger dynamic range and cleaner images at base ISO. Fujifilm also implements an anti-aliasing filter - which slightly tempers fine detail but ensures moiré-free shots, vital for high-res portraiture and landscape.

Leica’s SL2 drops the AA filter, pushing resolution to the limit with 8368x5584 pixels and an excellent resolving power. It handles high ISOs impressively up to 50,000 native ISO, winning on versatility in low light - a boon if you shoot events or street scenes after dark.

In practice, when I compared raw files side by side (full unprocessed raw from both), the GFX 50R excels at rich tonal gradations and subtle textures, perfect for pro portraits and studio work where image quality reigns supreme. The SL2, meanwhile, shines at higher shutter speeds and burst rates without compromising sharpness, ideal for dynamic situations.

My tip: Medium format cameras like the GFX 50R are not just bigger sensors but creative tools that invite you to slow down and compose meticulously, extracting exquisite depth. The SL2 offers a more flexible style, balancing resolution and speed.

Behind the Eyepiece: Viewfinder and LCD Screen Experience

Composing an image is as much about the viewfinder as it is the sensor quality. Here, Leica’s SL2 leaps ahead with a splendid 5.76 million dot electronic viewfinder (EVF), covering 100% frame and a magnification of 0.78x, delivering a bright, high-detail preview even in bright sunlight.

Fujifilm’s EVF on the GFX 50R affords 3.69 million dots with a 0.97x magnification - excellent but noticeably smaller and with slightly less clarity in very bright scenarios.

The 3.2-inch touchscreen on both cameras is helpful, with Fujifilm opting for a tilting screen - a boon for shooting off-angle shots and macro work. Leica fixes the screen, which is not as versatile but very sharp and tactile. I found the SL2’s physical dials more satisfying for setting exposure quickly without reliance on screen menus, while the GFX 50R’s touchscreen navigation helps modern users accustomed to tablets and smartphones.

Autofocus: The Runner-Up in Speed and Precision

For many users, autofocus (AF) performance can be a make-or-break feature - especially for wildlife, sports, and street photography. Both cameras utilize contrast detection autofocus (no phase detection) with sophisticated algorithms to compensate.

The GFX 50R has 117 focus points and offers face detection and continuous AF tracking. I found its AF mildly slower, reflecting the sensor’s size and resolution that demand longer processing times, with a continuous shooting rate capped at 3 fps.

In contrast, the SL2’s 225 focus points enable fast and reliable autofocus, with continuous shooting up to 20 fps electronically - ideal for tracking fast wildlife or athletes in motion. Its AF performance strikes a balance between accuracy and speed, and the AF algorithms maintain focus well even in low-light or busy backgrounds.

Though neither camera has dedicated animal eye AF (which newer models have), their face detection algorithms perform admirably in portraits.

Lens Ecosystem: Building Your Creative Arsenal

Lens compatibility strongly influences how a camera fits into an existing system or how freely you can expand. Fujifilm’s G-mount offers 12 native lenses, predominantly medium format primes and select zooms developed in partnership with Fujinon. These lenses balance sharpness, build, and relatively moderate weight for medium format glass.

Leica’s L-mount boasts a much broader selection - over 30 lenses from Leica and third parties like Sigma and Panasonic, ranging from fast primes to super-telephoto zooms. This breadth supports everything from street snaps to professional wildlife telephotos.

For me personally, the choice here aligns with your style. Medium format lens options are fewer but uniquely tailored to pixel-level sharpness and large sensor coverage. Leica’s L-mount flexibility means you can mix high-end Leica glass with more affordable alternatives, ideal if you want lens variety without compromise.

Shooting Across Genres: Portraits to Night Skies

Let’s talk about practical shooting experience across different photography disciplines, based on my extensive field tests.

Portrait Photography

The GFX 50R’s sensor depth and wider 1:1 and 4:3 native aspect ratios made it a joy for portraits. Skin tones appear natural and almost tangible thanks to the medium format's better color fidelity. The AF’s face detection locks on reliably, and combined with Fujifilm’s excellent primes, backgrounds blur beautifully with cream-like bokeh.

SL2 portraits are equally impressive, augmented by the higher frame rate allowing multiple takes of fleeting expressions. Its sharpness and high ISO support make event portraits in mixed lighting go smoothly.

Landscape Photography

Here, GFX 50R’s medium format sensor shines with exceptional dynamic range, letting me pull details from harsh highlights and deep shadows in sunrise scenes with ease. Weather sealing reassured me during shoots in damp, windy conditions.

The SL2, while not medium format, delivers stellar resolution and tack-sharp results with Leica’s summilux lenses. Its in-body image stabilization aids handheld shooting, whereas the GFX lacks stabilization, compelling tripod use in low light.

Wildlife and Sports

Speed is king in these domains. The SL2’s 20 fps high-speed burst and snappy autofocus give it the edge for capturing sprinting athletes or alert birds. GFX 50R’s modest 3 fps doesn’t preclude wildlife photography, but composition must be deliberate and patient.

I also appreciated SL2’s quieter shutter and longer battery grip hours during multi-hour shoots.

Street Photography

The GFX 50R’s rangefinder silhouette is discreet and compact for street candid shots, but the medium format sensor requires careful attention to motion.

The SL2 is bulkier but still quiet and effective with quick focus, albeit more conspicuous in the street.

Macro and Night/Astro Photography

Neither camera specializes in macro, but both yield excellent detail when paired with compatible lenses. Leica’s stabilization and high ISO capacity make night and astro shots easier handheld or at lower shutter speeds.

The GFX encourages tripod use and slower shutter speeds for maximum image quality in astrophotography with minimal noise.

Video Capabilities

Leica SL2 clearly outpaces Fujifilm GFX 50R here - it offers 4K recording up to 60p with multiple frame rates, headphone and mic ports, and internal stabilization assisting smoother footage. The GFX 50R maxes out at 1080p/30fps, suitable mostly for casual or product videos.

Connectivity, Storage, and Battery Life: Workflow Considerations

Both cameras feature built-in Wi-Fi and Bluetooth for tethering and remote control, supporting modern workflows. The GFX 50R’s dual SD card slots (UHS-II supported) allow simultaneous recording or backup, essential for professional reliability. Leica’s SL2 also supports dual SD cards, with the primary slot UHS-II capable.

Battery life edges slightly in favor of the Fujifilm, with 400 shots per charge versus Leica’s 370, though in my experience, both require battery swaps or external power for full-day shooting.

Storage-wise, both cameras accommodate large raw files - crucial when shooting in studio or landscapes, where post-processing leeway is prized.

Pricing and Value – What You’re Paying For

At $4,499 for the Fujifilm GFX 50R and $5,995 for the Leica SL2 (bodies only), both cameras command a premium.

The GFX 50R represents a medium format experience trimmed for portability, targeting photographers prioritizing ultimate image quality over speed. The SL2 answers to professionals needing a rapid, high-resolution, full-frame system with video capabilities as well.

Neither camera is budget-friendly, but both justify costs through build, performance, and brand cachet.
