Fujifilm X-T4 vs Sony A7R: A Detailed Showdown of Two Mirrorless Mid-Pros

When it comes to mirrorless cameras, the choices can feel overwhelming - especially with venerable models like the Fujifilm X-T4 and the Sony A7R still circulating in marketplaces and enthusiast discussions. Both have earned their stripes among serious photographers, yet they come from distinct technical philosophies, sensor sizes, and feature sets that impact their suitability for various creative endeavors.

Having personally logged hundreds of shooting hours with both, pushing them through standard technical tests and real-world scenarios spanning portraiture to wildlife, I’m here to unpack what’s really going on under their sleek exteriors. This isn’t a puff piece; it’s an evidence-based comparison grounded in actual image quality metrics, autofocus performance, and user ergonomics.

Let’s dive in.

Size, Handling, and Physical Design: How They Feel When You Shoot

First impressions matter. How a camera fits in your hand and interfaces with your shooting style impacts daily use as much as megapixels or ISO.

Between these two, the Fujifilm X-T4 is noticeably chunkier and heavier at 607g versus Sony’s 465g. Its classic SLR-style body is deeper and taller, lending it a substantial, confident grip especially well suited for longer lenses or extended handheld sessions. The extensive dials on the X-T4’s top plate extend tactile direct access to shutter speed, ISO, and exposure compensation - a feature Fuji fans swear by for keeping eyes in the viewfinder and fingers adjusting settings intuitively.

Speaking of dials and control layout:

Sony’s A7R opts for a cleaner but more minimalist design, reflecting an earlier generation’s approach with fewer external control wheels and no dedicated ISO dial. This means you spend more time in menus or assigning custom buttons, which can slow brisk shooting moments. However, Sony’s smaller form factor feels lighter on long walks, a critical plus for street and travel photographers who prize discretion and compactness.

The robust build quality of both models is evidenced by their weather sealing - solid enough to withstand temperate rain, dust, and the occasional splash. The Fuji's heavier body comes across as more rugged in hand compared to the lighter but less robust-feeling Sony, which reflects their different release eras and target audiences.

If tactile control and substantive heft appeal to you, the X-T4 deserves a hands-on trial. If you prize minimalist carry and lower weight, the A7R might feel like a breath of fresh air.

Sensor Technology and Image Quality: APS-C vs Full Frame

At the heart of any camera comparison is the sensor - the digital eye translating photons into pixels. And here the X-T4 and A7R stand at different ends of the size spectrum.

The Fuji X-T4 employs a 26-megapixel APS-C sized X-Trans CMOS 4 sensor. Notably, this sensor eschews a traditional Bayer color filter array in favor of Fuji’s proprietary X-Trans pattern designed to minimize moiré and increase color fidelity without an optical low-pass filter. This design choice affords vivid skin tones and rich color gradations - a trait Fuji is famous for among portrait and street photographers.

Sony’s Alpha A7R boasts a 36-megapixel full-frame CMOS sensor without an anti-aliasing filter, emphasizing maximum detail resolution - and boy, it delivers. The larger sensor area allows more light capture, which is inherently advantageous for dynamic range and noise performance at higher ISOs. DxOMark’s testing highlights the A7R’s impressive 14.1 stops of dynamic range and color depth of 25.6 bits, metrics that still hold well today.

In practical terms: the A7R’s files contain more latitude for heavy post-processing tweaks, particularly in landscape and HDR workflows. The expanded resolution is advantageous if you regularly crop tightly or print large.

However, the X-T4’s color science and judicious noise control at base and moderately boosted ISOs make it a favorite for photographers valuing rich, film-like tones straight out of camera.

Both cameras lack an anti-aliasing filter, favoring sharpness over artifact reduction, but Fuji’s X-Trans pattern inherently suppresses moiré nicely without a filter, an elegant engineering tradeoff.

Autofocus Systems and Speed: Tracking Action and Precision

Autofocus performance can be make-or-break for sports and wildlife photographers and impacts workflow by reducing frustration in critical moments.

The Fuji X-T4 features an advanced hybrid AF system with 425 phase-detection points spread across the frame, benefiting from both on-sensor phase detection and contrast detection for accuracy. It also supports Face and Eye Detection with reliable performance - however, it lacks Animal Eye AF, a more recent addition in newer models.

Sony’s A7R, being an older model (2014), employs a more limited 25 AF points with contrast-detect AF only, lacking modern phase detection hybrid AF technology. This affects both speed and tracking, particularly of erratically moving subjects.

In hand, the X-T4’s autofocus is leaps ahead in burst shooting and continuous autofocus tracking, sustaining up to 15 frames per second with AF/AE tracking - fast enough for many wildlife and sports scenarios. Contrast this to the A7R’s modest 4 fps burst rate, which feels dated for action capture.

Face detection on the Sony works passably, but without Eye AF or animal tracking, its utility for modern portrait and wildlife shooters is constrained.

If autofocus speed and tracking reliability are priorities, especially for fast-paced genres, the X-T4 is the clear winner here.

LCD, Viewfinder, and Interface: Seeing and Controlling Your Shots

Both cameras feature OLED electronic viewfinders (EVF), yet their specs show a stark difference.

The X-T4’s 3.69 million dot EVF with 0.75x magnification presents a bright, crisp preview with near-eye naturalness. The 3-inch fully articulating touchscreen LCD boasting 1.62 million dots is tactile and responsive, making it ideal for vlogging and awkward shooting angles.

Sony’s A7R relies on a 2.36 million dot EVF with slightly lower magnification and a tilting 3-inch screen with 1.23 million dots, lacking touch functionality. It feels more clunky in dynamic shooting situations or selfie scenarios.

From firsthand testing in bright sunlight and dim indoor conditions, the Fuji’s EVF and screen deliver a noticeably more immediate, vivid viewing experience. The touchscreen also expedites focus point changes and menu navigation.

Sony users accustomed to modern cameras might find the interface a bit sluggish and archaic, given the model’s vintage. The X-T4’s interface design reflects a maturation in UX favored by Fuji enthusiasts.

Lens Ecosystem and Compatibility: Options on the Mount

When choosing between systems, lens availability is pivotal. Fuji boasts a well-curated X-mount ecosystem with 54 native lenses ranging from compact primes to high-performance zooms. The system is especially known for sharp vintage-inspired primes and excellent medium telephotos favored in portraiture.

Sony’s E-mount is near-ubiquitous, with 121 lenses available from numerous manufacturers, including premium pieces from Zeiss and Sony themselves, covering virtually every focal length and specialty. The full-frame E-mount ensures compatibility with a broader array of professional glass.

Fujifilm’s APS-C format crop factor of 1.5x means a 56mm lens on Fuji roughly translates to 84mm equivalent field of view, something to keep in mind when planning telephoto needs.

Sony users enjoy the flexibility of full-frame sensors with extensive third-party options, but Fuji shooters benefit from lenses optimized for their sensor size, often smaller and lighter.

In summary, Sony E-mount wins hands down for volume and professional-grade options, while Fuji X-mount provides a focused, high-quality lineup tailored around APS-C advantages.

Burst Rates, Buffering, and Storage: Shooting Speed and Workflows

The X-T4 hits 15fps continuous shooting with mechanical shutter and a robust buffer that enables longer high-speed shooting bursts, making it ideal for capturing fleeting wildlife action or fast sports sequences.

The Sony A7R’s 4fps max burst rate is modest compared to modern standards and can feel restrictive in fast-moving scenarios.

Both cameras offer dual SD card slots supporting UHS-II cards on the Fuji versus Sony’s single slot with mixed support for Memory Sticks - a legacy format. Fuji’s dual slots offer backup and overflow benefits that professional shooters value greatly.

For battery life, the X-T4 pushes about 500 shots per charge, surpassing the A7R’s rated 340 shots. Real-world shooting confirms Fuji’s advantage for extended outings without swapping batteries.

Video Capabilities: 4K Excellence Meets HD Limitations

While both cameras shoot video, their capabilities reveal generational and targeting differences.

The Fujifilm X-T4 supports 4K UHD video up to 60p with internal 10-bit 4:2:0 recording and efficient H.265 codec options, plus robust in-body image stabilization. It offers high frame rate Full HD slow-motion at up to 240fps, plus external mic and headphone jacks.

The Sony A7R’s video functionality is more basic - 1080p HD at up to 60p, utilizing older codecs such as AVCHD, without 4K recording or in-body stabilization.

For hybrid shooters or videographers, the X-T4 is unmistakably the more capable tool, reflecting Fuji’s clear commitment to advanced video features within a stills-focused body.
