Both deliver sharp results; a6700 adds IBIS, 10‑bit video, AI tracking, and better ergonomics.
You want a small camera that punches above its size. I’ve shot trips, family days, and paid gigs with both. In my hands, the sony a6400 vs a6700 feels like a real choice: save money with the a6400, or step up to the a6700 for video and stabilization. I tested both side by side for weeks. Here’s what I learned so you can pick the right fit.

Is Sony a6400 Good?

Yes, the Sony a6400 is good. It is great for beginners, travelers, and hybrid shooters on a budget. It focuses fast, shoots sharp 4K, and packs light. If you do more photos than video, it shines. If you vlog with a gimbal, you will not miss stabilization.

On a weekend street session, the a6400 locked onto eyes as people crossed the frame. I got crisp shots with the small 35mm lens. On a city vlog, I flipped the screen up and framed myself with ease. The footage looked clean. The battery lasted a full afternoon of mixed clips.

What Makes It Stand Out / Key Features

• 24.2MP APS-C sensor with strong detail and color
• Real-time Eye AF for people and animals
• 4K up to 30p oversampled; 1080p up to 120p
• Flip-up selfie screen for vlogging
• Compact body with E-mount lens support

What I Like

• Fast, reliable autofocus for street and travel
• Clean 4K that still looks modern
• Lightweight body that packs in a small bag
• Flip screen makes solo shooting easy
• Great value in the sony a6400 vs a6700 debate if you are cost focused

What Could Be Better

• No in-body image stabilization (IBIS)
• 8-bit video only; less room for color grading
• Older battery and ports; shorter runtimes

My Recommendation

If you want a sharp, fast, budget-friendly hybrid, get the a6400. It is widely available and a smart value.

I filmed a run-and-gun interview in late light. The a6700’s IBIS steadied my handheld shots. Skin tones looked lovely in S-Cinetone. On a car shoot, the AI tracking stuck to the driver’s face even with sunglasses. The deeper grip and new menu made fast changes easy.

What Makes It Stand Out / Key Features

• 5-axis IBIS for steadier handheld shots
• 10-bit 4:2:2 video, 4K60, and 4K120 (crop)

• New battery and USB-C power for long days
• Deep features that scale with your skills

What Could Be Better

• Higher price than the a6400
• Body is a bit heavier
• 4K120 uses a crop, so framing is tighter

Best For	Why
Solo filmmakers and vloggers	IBIS, 10-bit, and AI subject tracking
Hybrid pros	Better codecs, ports, and power options
