Overall, if you prefer a more traditional, tactile interface and a substantial grip, you’ll appreciate the X-T4’s handling. Sony’s design caters well to those seeking a streamlined, more compact experience.

Sensor and Image Quality: Resolution, Dynamic Range, and ISO Performance

When evaluating cameras, the sensor is the heart, and this is where the two differ significantly.

• Fujifilm X-T4: APS-C sized X-Trans CMOS 4 sensor (23.5x15.6mm) with 26MP resolution, no optical low-pass filter for sharper images. Fuji’s X-Trans color filter array is renowned for faithful skin tones and pleasing color rendition.
• Sony A7R II: Full-frame 42.4MP back-illuminated CMOS sensor (35.9x24mm), also with no optical low-pass filter, offering significantly more native resolution.

Real-world impact:
The A7R II’s full-frame sensor captures images with spectacular detail and excellent dynamic range, measured at roughly 13.9 EV stop range on DxOMark - ideal for landscape and studio photographers who value high resolution and shadow detail. Its native ISO range up to 25600 (boosted to 102400) allows flexibility in lower-light environments, although noise becomes noticeable at the top end.

The X-T4’s 26MP APS-C sensor is smaller but punches well above its class, delivering rich colors, exceptional sharpness, and a clean ISO range up to 12800, expandable to 51200. Fuji’s film simulation modes emulate classic film looks, beneficial for street and portrait photographers seeking out-of-camera aesthetics.

From my tests shooting both in controlled studio and outdoor scenes, Sony’s larger sensor produces files with higher print potential and dynamic range benefits, while Fuji’s sensor offers quicker readout speeds and vibrant colors straight out of the camera.

Autofocus Systems: Speed, Accuracy, and Tracking

Fast and reliable autofocus (AF) is critical for most photography genres, especially action and wildlife.

• Fujifilm X-T4 AF: 425-point hybrid AF system (phase-detect + contrast-detect), including face and eye detection. Continuous AF shoots at up to 15fps with focus tracking.
• Sony A7R II AF: 399-point phase-detection AF points covering 45% of the frame, plus contrast detection. Max continuous shooting at 5fps.

I found the X-T4’s AF to be quicker to lock under varied conditions, especially in continuous tracking mode. Fuji’s algorithm shines for portraits and street photography, reliably maintaining eye detect and face tracking. In wildlife and sports, its 15fps burst rate with AF tracking makes a big difference, capturing fleeting moments better than Sony’s slower frame rate.

The A7R II’s AF is precise but generally slower, with occasional hunting in low light or fast subjects. However, the sensor’s resolution compensates somewhat by allowing cropping for composition adjustments.

Viewing Experience: EVF and LCD Screen Performance

A camera’s electronic viewfinder (EVF) and rear LCD are your windows to the image and workflow interface.

• Fujifilm X-T4: 3.0-inch fully articulating touchscreen with 1.62M dots, plus a high-res 3.69M-dot EVF with 0.75x magnification.
• Sony A7R II: 3.0-inch tilting LCD screen (non-touch) at 1.23M dots and a 2.36M-dot EVF with 0.78x magnification.

The Fuji’s touch-enabled articulating screen offers incredible flexibility - ideal for vloggers, macro shooters, and awkward-angle framing. The EVF is bright, sharp, and provides natural colors with minimal lag. During my extensive shooting, the touch interface sped up menu navigation and focus selection noticeably.

Sony’s EVF delivers good clarity but lags behind Fuji’s in resolution and responsiveness. The non-touch screen limits quick menu access and focus adjustments, though it’s perfectly adequate for traditional compositions.

Lens Ecosystem and Compatibility

Choosing a camera often comes down to available lenses.

• Fujifilm X-T4: Fujifilm X mount with over 50 native lenses, many known for excellent optics in a compact form factor. The range covers everything from ultra-wide to super-telephoto, with stellar primes for portraits and macro.
• Sony A7R II: Sony E mount with over 120 native lenses from Sony and third parties like Sigma, Tamron, and Zeiss, including many full-frame options.

The Sony system offers greater versatility if you need specialized lenses or want access to a broad selection. Fuji’s lens lineup specializes in high-quality primes and compact zooms, perfect for everyday use and travel.

While I tested both with comparable zoom and prime lenses, the A7R II’s lens choices support extreme resolution better in professional studios. Fuji’s lenses balance optical quality and portability superbly for on-the-go shooters.

Burst Shooting and Buffer Depth: Capturing Fast Action

Sports and wildlife photographers need reliable burst performance.

• X-T4 shoots up to 15fps with mechanical shutter (30fps electronic silent shutter).
• A7R II maxes out at 5fps mechanical shutter.

Fuji wins hands down here. In real use, the X-T4’s deep buffer allows longer continuous bursts with AF tracking. The Sony’s buffer fills quicker, limiting extended action sequences. For capturing decisive moments in sport or wildlife, this is a crucial advantage for Fuji.

Video Capabilities: Specs and Practical Use

Both cameras support 4K video but differ in codec and frame rates:

• Fujifilm X-T4: 4K DCI/UHD up to 60p 10-bit 4:2:0 internal recording (H.265), plus F-Log profiles and advanced IBIS (in-body image stabilization).
