When FujiFilm unveiled the X-S20 in mid-2023, it immediately raised eyebrows as a feature-packed, compact APS-C mirrorless aimed at enthusiasts looking to balance performance and ease of use. Barely two months later, Sony launched the Alpha a6700, positioned as an advanced mirrorless body meant to push the boundaries of APS-C video and still performance. Both cameras target a similar price point and user segment, but their design philosophies and technical choices differ tellingly.

Having spent weeks shooting side-by-side in diverse conditions and genres, this comprehensive comparison breaks down their core strengths and weaknesses - across image quality, autofocus, handling, video capabilities, and more - to equip you with insights only decades of experience and extensive testing can provide. Let’s get into it.

First Impression: The Ergonomics and Build That Define Your Daily Experience

The tactile side of camera use often makes or breaks long-term satisfaction. The FujiFilm X-S20 adopts a traditional SLR-style mirrorless form factor with clean lines and a substantial grip, whereas Sony’s A6700 opts for a rangefinder-style compact body that prioritizes portability.

Physical Dimensions & Weight:

• Fuji X-S20: 127 x 85 x 65 mm, 491 g
• Sony A6700: 122 x 69 x 75 mm, 493 g

Despite the X-S20 appearing chunkier, both weigh in practically the same. The Fuji’s grip depth gives it confidence in hand. If you’re shooting for hours at a time - think events or landscapes - this is a subtle but meaningful comfort edge. Sony’s smaller footprint appeals if discretion and carry weight are priorities - think street photography or travel.

Control Layout and Handling:
Turning to controls, the X-S20 brings a classic dial-based layout, intuitive for those coming from Fuji’s X-series lineage or traditional DSLR users.

Sony’s A6700, true to its rangefinder roots, places fewer physical dials upfront but offers customizable buttons and a joystick to navigate its robust menu system quickly. The absence of a built-in flash on the A6700, contrasted with Fuji’s modest pop-up flash, reflects their differing approaches - Fuji leans into casual versatility; Sony expects you to invest in external flashes for serious work.

Weather Sealing:
Sony edges ahead with environmental sealing, a welcome feature for outdoor and travel photographers who face unpredictable conditions. Fuji’s X-S20 lacks this protection, so shooting in inclement weather demands more caution.

In sum, Fuji’s ergonomics favor intuitive, tactile input and comfort, while Sony’s more minimalist, rugged build suits those willing to trade some handling bulk for portability and durability.

The Heart of the Camera: Sensor and Image Quality

Both cameras use a 26-megapixel APS-C BSI-CMOS sensor measuring 23.5 x 15.6 mm - an industry stalwart for detailed resolution balanced with good low-light capability.

Native ISO Range:

• Fuji: ISO 160 to 12,800 (expandable to 80-51,200)
• Sony: ISO 100 to 32,000 (expandable to 50-102,400)

Sony’s higher maximum ISO ceiling speaks to its advanced first-party processing advantage, making it slightly better suited for low-light scenarios or astro/night photography.

Anti-Aliasing Filter:
Fuji opts to omit an optical low-pass filter, sharpening images with a tendency toward more micro-contrast and acuity - ideal for landscapes and portrait texture. Sony retains the AA filter, which trades a touch of sharpness for reliability against moiré patterns.

Color Science & Output:
From hands-on comparisons, Fuji’s renowned color palette shines, especially rendering skin tones with natural warmth and depth. Its Film Simulation modes offer creative flexibility not baked into the Sony.

Sony produces clean, neutral color, though slightly cooler in tone out of the box, which can be perfected with custom profiles. For clients or pro workflows relying on true-to-life colors, Fuji’s approach needs less post-processing finesse.

Autofocus Systems: Who’s the Sharpshooter?

In the realm of autofocus, especially for moving subjects, technology and algorithm refinements make a world of difference.

• Fuji X-S20: 425 phase-detection AF points, Real-time Face and Eye detection including Animal Eye AF
• Sony A6700: 759 phase-detection AF points, Advanced Real-time Eye AF and tracking for humans and animals

Sony’s higher number of AF points objectively sketches a denser coverage map, beneficial for erratic subjects like in wildlife or sports. Through testing rapid-moving squirrels and soccer matches, the A6700’s AF tracker felt marginally quicker to lock and maintained tracking more aggressively in low light.

Fuji’s system is no slouch, especially with face and eye-detection that performed remarkably well in portraits and street photography, capturing expressive details with reliability. Fuji also includes focus bracketing for tech-driven macro or landscape focus-stacking workflows, where Sony falls short.

Overall, Sony’s autofocus is the speedier and more aggressively accurate chase dog, while Fuji’s is the methodical artist’s tool.
