🧱 Build and Handling
The Fujifilm X-S10 strikes a perfect balance between compactness and comfort. Its deep grip feels like a mini DSLR, making it easy to hold even with larger lenses. The fully articulating screen makes it great for vlogging and creative angles.
The Sony A6400, by contrast, is smaller and lighter, with a robust magnesium-alloy body. However, its menu system feels less intuitive, and the lack of IBIS means you’ll rely on stabilized lenses.
👉 Verdict:
-
X-S10: Better ergonomics and stabilization.
-
A6400: Smaller, tougher, and travel-friendly.
🎯 Autofocus and Speed
Here’s where the Sony A6400 takes the lead.
Sony’s Real-Time Tracking AF and Eye AF are among the best in the industry — extremely fast, accurate, and reliable in both photo and video modes.
The Fujifilm X-S10 also offers strong autofocus performance with face and eye detection, but it’s not quite as instantaneous as Sony’s system, especially in continuous tracking.
👉 Verdict:
-
A6400: Industry-leading autofocus performance.
-
X-S10: Very good AF, but not as predictive for moving subjects.
