Fujifilm X-T4 vs Sony A6700: A Deep Dive to Find Your Next APS-C Mirrorless Workhorse

Having personally handled and tested thousands of cameras over the past 15 years, I approach this Fujifilm X-T4 and Sony A6700 comparison not as a mere spec sheet duel but as a practical exploration of what these two flagship APS-C mirrorless models can genuinely deliver in the field. Both are advanced models from two titans of the mirrorless world, aimed at enthusiasts and pros seeking top-tier image quality, speed, and versatility without the bulk and cost of full-frame.

I have taken them through a gamut of shooting scenarios - portrait sessions, wilderness treks, fast-paced events, and long travel days - to see where each shines and where compromises lurk. Let’s dig in.

Ready, Set, Touch and Feel: Ergonomics and Design Face-Off

When you hold a camera for hours, the physical experience shapes your work more than any spec on paper. The Fujifilm X-T4 carries the classic SLR-style mirrorless feel - chunky, substantial, and solid. Weighing in at 607g with dimensions of 135 x 93 x 64 mm, it has a pronounced grip and robust build with environmental sealing that gives confidence shooting in variable weather.

The Sony A6700 moves toward a streamlined rangefinder style in a smaller, lighter body at 493g and 122 x 69 x 75 mm. While compact and undeniably travel-friendly, my hands found it less comfortable over long shoots compared to Fuji’s heftier grip profile.

Both feature fully articulated 3-inch touchscreens, but the Fuji's screen boasts a higher resolution at 1620k dots versus Sony’s 1040k, lending more precision during focus checks. The top-panel layout also splits opinions: Fujifilm sticks to tactile dials for ISO, shutter speed, and exposure compensation giving an analog control feel, while Sony adopts a more streamlined button and dial setup that might appeal to those used to its Alpha series.

In practice, Fuji's dials offer quick, tactile feedback, great for spontaneous adjustments without diving into menus, a real boon for shooting dynamic scenes. Sony benefits from its compactness but demands more reliance on the touchscreen or custom buttons to tweak exposure - something I personally find slightly slower in fast action.

Practical takeaway: If you crave a robust, tactile interface with classic controls that keep eyes on the scene, the X-T4 edges ahead. For lightweight carry and a subdued presence, the A6700 suits well.

APS-C Sensors: The Battle of X-Trans CMOS 4 vs Sony BSI-CMOS

Both cameras pack 26-megapixel APS-C sensors with a 1.5x crop factor but diverge in sensor technologies. Fuji’s X-T4 uses its proprietary X-Trans CMOS 4 sensor without an optical low pass filter (OLPF), preserving maximum sharpness and detail. Sony’s A6700 shifts to a traditional BSI-CMOS sensor layered with an OLPF to balance resolution and moiré suppression.

Real-world shooting confirms Fuji’s X-Trans sensor delivers exquisite detail and texture rendition, especially noticeable in landscape and portrait work where fine nuances in skin tones and foliage come alive. The absence of an anti-aliasing filter invites slightly punchier files that benefit larger prints.

Conversely, Sony’s sensor excels in high ISO performance with extended native ISO up to 32,000 and boosted to 102,400. I pushed both cameras in a low-light astrophotography session and found the A6700 maintains cleaner shadows and smoother gradations in the deeper shadows, albeit with a touch less fine detail than Fuji.

Color science is personal, but the X-T4’s renowned film simulations and natural skin tone rendering favored portrait sessions immensely. Sony’s files offer a more neutral starting point, ideal for those who prefer heavy editing in post or video workflows due to their more linear color curves.

Summary: Fuji suits photographers prioritizing ultimate sharpness and color nuance, while Sony leans toward higher ISO flexibility and smoother gradients under challenging lighting.

Eye on Autofocus: Speed, Accuracy, and Intelligent Tracking

Autofocus (AF) technology can make or break your photo shoot, especially in wildlife and sports. The X-T4 boasts 425 phase-detect AF points spread widely, leveraging contrast detection to fine-tune focus accuracy. Sony steps up with an impressive 759 AF points, including real-time eye and animal eye AF for humans and wildlife.

In practical experience, the Sony A6700’s animal eye autofocus is a genuine asset for wildlife photographers. During a birding trip, I could lock focus quickly on moving subjects, even under dense foliage. The X-T4 proved capable but required a more deliberate approach to tracking small erratic subjects.

For sports, I found Fuji’s continuous AF and 15 fps mechanical shutter speed delivered excellent action capture, but Sony's 11 fps is not far behind, coupled with a lower blackout time in the EVF, allowing better subject tracking.

In portraiture, both have facial and eye AF, but Sony's latest algorithm felt slightly more reliable in very low contrast lighting or when subjects were turning their heads swiftly.

Both cameras support touch AF on their rear screens for rapid refocus, critical for street and documentary shooters.

In the Field: Build, Durability, and Weather Sealing

I tested both bodies through rain-soaked trails and dusty environments to evaluate sealing. Both cameras are weather resistant but not fully waterproof. The X-T4’s magnesium alloy body felt exceptionally rugged, with a snug grip and sealed buttons that inspired shooting confidence in adverse conditions.

Sony’s A6700 also features environmental sealing but felt a tad less sturdy under punishing conditions, partially due to its lighter build. The lack of dual card slots (offered only on Fuji) could be a dealbreaker for professionals requiring in-camera redundancy for reliability.

Viewing and Interface: Screens and Viewfinders Compared

A key usability factor is how you compose shots and review images. Fujifilm’s EVF impresses with 3.69 million dots at 0.75x magnification, delivering crisp, bright, and immersive framing. Sony’s viewfinder, while slightly smaller at 2.36 million dots and 0.71x magnification, still holds high fidelity but does feel less immersive in comparison.

The articulated touchscreen displays on both cameras aid creativity with selfie-friendly flips and touch-to-focus. Fuji’s higher resolution screen provides more clarity when confirming focus or zooming in on images, especially beneficial for macro or landscape photographers inspecting details.

Choosing Lenses: What Does the Ecosystem Offer?

Fujifilm’s X-mount boasts 54 native lenses - a curated range of primes and zooms celebrated for optical quality, especially within the renowned XF prime series. The vintage character of some lenses complements Fuji’s film simulations, delivering an inimitable look straight from the camera.

In contrast, Sony’s E-mount commands a vast arsenal of 199 lenses, from Sony’s own G Master premium glass to third-party options like Sigma and Tamron. This breadth provides unmatched versatility and future-proofing for any genre, from ultra-wide landscapes to super telephoto wildlife lenses.

For macro enthusiasts, both brands offer specialized optics, but Fuji lacks optical stabilization in most macro primes, relying on in-body image stabilization (IBIS). Sony’s newer lenses and IBIS provide excellent combined stabilization in closer focus distances.

Burst Rates and Buffer: How Do They Handle Speed?

For wildlife and sports photographers, frame rate and buffer depth are crucial. Fuji’s X-T4 shoots up to 15 fps with the mechanical shutter and can reach 30 fps with the electronic shutter, though with some rolling shutter artifacts. Sony’s A6700 maxes at 11 fps mechanically and speeds up to 20 fps electronically, with a slightly deeper buffer for extended bursts.

In real-world tests, Fuji was fantastic for fast-moving subjects but suffered minor blackouts in the EVF at max speeds. Sony balanced speed with more consistent EVF visibility, aiding tracking.

Video Capabilities: 4K and Beyond

Both cameras target hybrid shooters with robust video specs.

The Fujifilm X-T4 stands out with 4K up to 60p at 10-bit 4:2:0 internally and 4:2:2 externally via HDMI. This, combined with Fujifilm’s renowned color science and F-Log, makes it strong for creatives seeking cinematic footage. IBIS combined with digital stabilization ensures smooth handheld takes.

Sony’s A6700 doubles down with 4K 120p slow motion at 10-bit internally - ideal for action videographers and sport shooters - though limited to 4K 30p for extended recording durations. Sony also supports high-bitrate XAVC HS format, delivering superior compression efficiency. The inclusion of both mic and headphone jacks pleases vloggers and sound recordists.

If video is a primary use case, Fuji offers a slightly more filmmaker-friendly interface with tactile controls, while Sony appeals with frame rate options and high bitrate codecs.

Battery Life and Storage: Endurance on the Trail

Sony's A6700 boasts approximately 570 shots per charge (CIPA rating), outperforming Fuji’s 500 shots. This makes Sony preferable for travel and long-day shooting without frequent battery swaps.

Storage-wise, Fuji X-T4 offers dual SD UHS-II card slots supporting in-camera backup and overflow, critical for professionals when redundancy is a must. Sony A6700 has a single slot and supports SD and Memory Stick Pro Duo (a legacy format), which might disappoint those wanting maximum flexibility.

Price Versus Performance: What’s the Value Proposition?

At current street prices, Fujifilm X-T4 sits around $1700 body-only, while Sony A6700 goes for about $1400, making the Sony a more budget-friendly choice, especially for those entering the advanced APS-C arena.

The premium for Fujifilm gains you dual card slots, faster mechanical shutter speeds, higher resolution EVF, and famed color science. If these benefits align with your shooting priorities, the extra $300 is justified.
