Sony A6400 & Sony A7 II share many similarities, but there are also important differences, such as quality, performance, features, design, and connectivity. If you want the best one between them, I Would recommend the Sony A6400 rather than the Sony A7 II.
Why Do I Recommend The Sony A6400?
- The Sony A6400 has a 425-point phase-detect autofocus system for faster and more accurate subject acquisition across most of the frame, while the Sony A7 II uses a 117-point phase-detect autofocus system.
- Sony A6400 supports real-time tracking autofocus for maintaining continuous focus on moving subjects during sports and wildlife shooting, whereas the Sony A7 II lacks real-time tracking autofocus.
- It includes real-time Eye AF for humans and animals to keep eyes sharply focused in portraits and action scenes, while the Sony A7 II uses a basic Eye AF system limited to human subjects.
- The Sony A6400 records oversampled 4K video from a 6K readout for sharper detail and reduced moiré in video footage, while the Sony A7 II records only Full HD video.
- Sony A6400 shoots up to 11 frames per second for capturing fast-moving moments with more usable frames, while the Sony A7 II shoots up to 5 frames per second.
- It features an electronic shutter for completely silent shooting in events, wildlife, or quiet environments, whereas the Sony A7 II relies on a mechanical shutter only.
- The Sony A6400 comes with a 180-degree flip-up LCD screen for easy self-recording and vlogging, while the Sony A7 II uses a tilt-only LCD screen.
- Sony A6400 has a significantly lighter and more compact body for improved portability and reduced fatigue during travel and long handheld sessions, compared to the Sony A7 II’s heavier body.
Maybe the Sony A7 II can make you comfortable because it’s a little bit cheaper than the Sony A6400. But you have to compromise all the above-mentioned features. Now the Decision is Yours. I hope it was helpful to choose the right one.

What Common Both Can Do?
- Lens Mount: Both cameras use Sony’s E-mount, allowing access to a wide ecosystem of native Sony lenses and third-party options. This compatibility makes it easier to share lenses across APS-C and full-frame Sony mirrorless systems.
- Mirrorless Design: Each model is built around a mirrorless architecture, enabling shorter flange distance and more compact body construction. This design also supports advanced autofocus and real-time electronic viewfinder previews.
- Interchangeable Lenses: Both cameras support interchangeable lenses, giving photographers flexibility to choose optics for portraits, landscapes, sports, or video work. This adaptability is essential for growing skill levels and varied shooting needs.
- CMOS Sensor Type: Sony A6400 and Sony A7 II both use Exmor CMOS sensors, which are known for efficient light capture and low-noise performance. This sensor technology contributes to reliable image quality across different lighting conditions.
- Image Processor Family: Both models rely on Sony’s BIONZ X image processor family for image handling. This ensures consistent color science, noise reduction behavior, and overall image rendering between the two cameras.
- RAW Capture: Each camera supports RAW file capture, allowing photographers maximum flexibility in post-processing. RAW files preserve more detail and dynamic range than compressed formats.
- Rear LCD Screen: Both cameras include a rear LCD for image playback, menu navigation, and live view shooting. The screen enables flexible composition when shooting at unusual angles.
- Wi-Fi Connectivity: Wireless connectivity is built into both models, enabling image transfer to smartphones or tablets. This feature simplifies sharing photos without removing the memory card.
- NFC Support: Each camera includes NFC for quick pairing with compatible devices. This allows faster setup when transferring images or controlling the camera remotely.
- USB Connectivity: Sony A6400 and Sony A7 II both feature USB ports for data transfer and charging. USB support improves workflow efficiency when working with computers or power banks.
- HDMI Output: Both cameras provide HDMI output for external displays or recorders. This is useful for studio work, monitoring, or video production setups.
- Silent Shooting Option: Each model supports silent shooting via electronic shutter modes. This is beneficial for events, wildlife, or quiet environments where shutter noise is disruptive.
- Dust & Moisture Resistance: Both bodies include basic sealing against dust and moisture. This adds durability for outdoor shooting in less-than-ideal weather conditions.
- Hot Shoe: Each camera features Sony’s Multi Interface Shoe for flashes and accessories. This ensures compatibility with a wide range of lighting and audio equipment.
- Battery Type: Both cameras use the NP-FW50 battery, allowing shared batteries and chargers. This is convenient for users who own multiple Sony mirrorless bodies.
