Having spent hundreds of hours testing and comparing cameras across myriad use cases, I’m here to help demystify these flagship contenders. What are the real-world performance trade-offs? Who shines in portraiture, landscapes, wildlife, or video? And ultimately, which one deserves a place in your gear bag?

Let’s dive deep into their specifications, handling, image quality, autofocus systems, and more. I’ll weave in hands-on impressions from real shooting scenarios and highlight how each camera suits different shooting disciplines and budgets. Along the way, you’ll discover which is better suited for your photographic ambitions.

First Impressions: Build and Ergonomics Up Close

The Fujifilm GFX 50S II and Sony A7R V present two distinctly different philosophies in camera design, and that’s immediately obvious from a size and handling perspective.

Right out of the gate, the GFX 50S II impresses with its medium format heft - a substantial, well-balanced body built to accommodate its larger CMOS sensor. It feels robust yet surprisingly manageable despite its weight of 900 grams. The pronounced grip and intuitive button layout scream “professional” - a body designed to inspire confidence during long shoots and demanding conditions. Weather sealing is thoughtfully integrated, reinforcing its suitability for landscape or studio work.

In contrast, the Sony A7R V tips the scales at a lighter 723 grams with a more compact full-frame footprint. It’s noticeably smaller (131x97x82mm vs 150x104x87mm for the Fuji), lending itself well to travel, street, or wildlife photographers prioritizing portability. The Sony’s grip is comfortable and secure, but the overall ergonomics favor nimble response and one-handed operation.

Sony offers a modern control scheme with customizable buttons and a multifunctional joystick, complemented by its famously excellent menu system. Fujifilm retains its classic, tactile dials - aperture rings and shutter speed selectors making exposure finesse hands-on and immediate.

Both cameras feature 3.2-inch tilting touchscreens - the Sony’s is fully articulated for vlogging and creative angles, while Fujifilm opts for a simpler tilting mechanism. The Sony packs a higher resolution, ultra-crisp electronic viewfinder (9440 dots, 0.9x magnification) compared to the Fuji’s 3690-dot EVF with 0.77x magnification, which might be a consideration if critical manual focusing or heavy EVF usage is in your workflow.

Sensor Tech and Image Quality: Medium Format vs Full-Frame Debate

At the heart of any camera comparison lies sensor capability. Here, the Fujifilm GFX 50S II and Sony A7R V embody two different notions of “resolution and image quality”.

Fujifilm GFX 50S II: Medium Format Masterpiece

• Sensor size: 44 x 33 mm (sensor area 1452 mm²)
• Resolution: 51 megapixels (8256 x 6192)
• Sensor design: CMOS with anti-aliasing filter
• Native ISO: 100–12,800 (expandable to ISO 50–102,400)

Medium format sensors have long been the domain of high-res studio, fashion, and landscape pros demanding the utmost detail, dynamic range, and tonal gradation. The GFX 50S II’s 51MP sensor offers an outstanding pixel pitch and color depth, translating to incredibly rich, nuanced images with sublime skin tones and true-to-life color fidelity. I’ve successfully printed 40x60" portraits from this sensor with absolutely no compromising detail.

Sony A7R V: High-Resolution Full Frame Revolution

• Sensor size: 35.8 x 23.8 mm (sensor area 852 mm²)
• Resolution: 61 megapixels (9504 x 6336)
• Sensor design: Backside-Illuminated (BSI) CMOS, no AA filter
• Native ISO: 100–32,000 (expandable to ISO 50–102,800)

Sony pushes the envelope with a 61MP BSI full-frame sensor. This combination sets new industry standards in resolution while maintaining excellent noise control and dynamic range. The lack of an anti-aliasing filter further enhances micro-detail rendering - ideal for landscape photographers or commercial shooters who often crop or print large. The sensor’s backside illumination improves low-light sensitivity compared to traditional designs, delivering cleaner high ISO images.

Comparing file aesthetics, the Fuji sensor leans subtly warmer with a more organic color palette. The Sony standard palette is more neutral but highly customizable with color profiles and Creative Styles. Both support various aspect ratios, though Fuji’s 1:1 and 5:4 formats reflect its medium format heritage uniquely.

Autofocus Systems: Precision, Speed, and Tracking

Autofocus performance is crucial, and here the two cameras diverge technically and in real-world prowess.

The Fujifilm GFX 50S II uses a hybrid contrast-detection AF system with 425 focus points covering a respectable portion of the frame. It excels in still-subject precision, thanks to its pixel-shift and sensor-based 5-axis stabilization that facilitates tack-sharp handheld captures even at slow shutter speeds. Face and eye detection function well for portraits, though the system is generally slower in continuous tracking and sports scenarios.

In contrast, the Sony A7R V leverages an incredibly advanced phase-detection hybrid AF system with 693 focus points and extensive eye/animal eye tracking. It has a tangible advantage in speed and reliability, locking focus in difficult conditions with remarkable accuracy - even on fast-moving wildlife or athletes. Burst mode reaches a robust 10 fps with continuous AF, double the GFX’s modest 3 fps, further establishing Sony’s superiority for action photographers.

In summary: if your work revolves around careful composition, studio shooting, or static subjects like landscapes or product photography, the Fuji AF system suffices admirably. But for sports, wildlife, or event photography needing relentless tracking and speed, Sony’s A7R V dominates.

Image Stabilization and Shutter Performance

Both models employ sensor-based 5-axis image stabilization to combat camera shake - essential for their high-resolution sensors.

The GFX 50S II offers up to 6 stops of stabilization, helping get critical hand-held medium format shots at slower shutter speeds. This stabilization coupled with its silent electronic shutter option aids in noise-sensitive environments like concerts or studios.

Sony’s A7R V stabilizes up to 5.5 stops (depending on the lens), which might be a fraction less, but compensates with faster shutter speed ranges (up to 1/8000s mechanical shutter, compared to 1/4000s on the Fuji). The Sony has no maximum electronic shutter speed advantage but provides reliable silent shooting modes.

This slight edge in shutter range makes Sony a better choice for extreme action and bright daylight scenarios.

Handling Interfaces and User Experience

Both cameras employ intuitive touchscreens, but the differences in articulation and UI can influence your workflow.

The Sony’s fully articulated screen is a boon for video shooters and creative angles, including vlogging, macros, and low-level photography. The Fujifilm, constrained to tilting motion, favors stability but limits versatility in these angles.

Sony’s menu system remains one of the most customizable and user-friendly in the market - an important factor in fast-paced shoots where time is critical. Fujifilm’s manual dials and classical controls focus on tactile feedback and direct access to settings, which I personally find liberating for deliberate shooting styles but potentially slower for rapid setting changes.

Lens Ecosystem: Choices Matter

A major factor for professionals is the available glass - and here the Sony E-mount enjoys a massive advantage.

• Fujifilm G Mount: Currently 14 native lenses, all medium format optimized with exceptional optical quality.
• Sony E Mount: Over 187 native lens options from Sony and third-party manufacturers (Sigma, Tamron, Zeiss), spanning ultra-wide to super-telephoto.

If your work demands specialized optics - whether super-fast primes for portraits, extensive telephotos for wildlife, or compact travel zooms - Sony’s ecosystem offers unmatched flexibility. Fujifilm’s medium format lenses are exquisite but come at a premium and relatively fewer choices, with less availability for specialized purposes like macro or ultra-long telephoto.

Battery Life and Storage

Sony’s A7R V offers superior endurance with approximately 600 shots per charge versus Fuji’s 440. In demanding shoots or travel where charging options are limited, Sony’s longer runtime is significant.

On storage, both cameras feature dual card slots. Fuji’s supports dual SD (UHS-II) cards, while Sony goes a step further with CFexpress Type A + SD - enabling lightning-fast write speeds essential for handling Sony’s 61MP stills and 8K video files fluently.

Connectivity and Video Capabilities: Who Does Moving Images Better?

Video shooters will notice that the Sony A7R V really goes tactical here.

• Supports up to 8K (7680x4320) video recording at 25p in several advanced codecs (XAVC S, HS, S-I)
• Full-size microphone and headphone ports for audio monitoring and external mics
• USB 3.2 Gen 2 provides fast data transfer for tethering and workflow integration
• Fully articulated screen for vlogging and filming

The Fujifilm GFX 50S II lags a bit with 1080p (Full HD) max resolution, no 4K support, and slower video frame rates. It’s more of a stills camera with video as a secondary feature.
