🧱 Build, Handling & Portability

The A6400 offers a compact, lightweight body which makes it a strong choice for creators who want high performance while keeping gear manageable.
The A6700, while still APS-C, carries additional features (IBIS, larger battery, enhanced internals) and thus may be slightly larger or heavier. The boost in spec justifies that for many users.

👉 Verdict:

• Choose A6400 if portability, cost-efficiency and proven performance matter most.

• Choose A6700 if you’re comfortable with the additional investment and want more power/features for the future.

---

🎯 Autofocus & Performance

Autofocus is a standout for both—but the A6700 takes it further. The A6400 introduced very fast AF and reliable tracking for its time. The A6700 upgrades to many more focus points, improved tracking algorithms and better performance for both photo and video.

👉 Verdict:

• For fast-moving subjects, action, video-centric shooting: A6700 has the edge.

• For stills, general hybrid use and value: A6400 remains very capable.

---

🎥 Video & Hybrid Capabilities

Video workflows benefit a lot from advanced features.

• The A6700 offers higher frame-rate video, modern codecs, possibly better low-light and dynamic range due to newer sensor and processor.

• The A6400 provides strong video potential (4K, good AF) and remains a good value for creators who don’t need the absolute top tier.

👉 Verdict:

• If video-heavy or future-looking creator: go A6700.

• If hybrid use with stills predominant, value matters: A6400 fits well.

---

🧠 Image Quality (Stills)

Both cameras deliver excellent still image quality. The jump in sensor resolution and processing in the A6700 will benefit bigger prints, cropping flexibility and longer life-cycle. The A6400 remains very solid.

👉 Verdict:

• If you aim for top image quality and future-proofing: A6700.

• If stills are important and budget is key: A6400 gives nearly all you need.

---

🔋 Ecosystem, Lenses & Future-Proofing

Both use Sony E-Mount, so lens and accessory support is excellent in both cases. The main difference is that the A6700’s newer spec means it’s more future-proof for upgrades and advanced workflows.

👉 Verdict:

• Lens mount: both win.

• Future upgrade: A6700 slightly ahead due to newer architecture.

---

💰 Price & Value

Given its earlier release and fewer high-end features, the A6400 usually comes at a lower price point, offering strong value. The A6700 commands a premium but brings more features.

👉 Verdict:

• For value: A6400.

• For premium investment: A6700.
