Autofocus System

One of the standout features of the Sony a6400 is its autofocus system. It’s equipped with 425 phase-detection and 425 contrast-detection points. Here’s what you can expect:

  • Tracking Performance: The real-time tracking and Eye AF (autofocus) are game-changing. They allow you to maintain focus on moving subjects, ensuring sharp images. Eye AF is particularly useful for portraits, keeping the focus on the subject’s eyes for stunning details.

Image Quality

The Sony a6400 produces high-quality images that are sure to impress. Here’s what you need to know about its image quality:

  • Color Reproduction: The colors are vibrant yet natural. Whether you’re capturing landscapes or portraits, the camera reproduces colors accurately, giving your photos a lifelike quality.
  • Dynamic Range: With a dynamic range of around 13 stops, the a6400 can handle a wide range of lighting conditions. This means your images will retain detail in both highlights and shadows, even in challenging light.
  • Noise Performance: At lower ISO levels, noise is minimal, producing clean and crisp images. As you increase the ISO, noise does become more apparent but remains well-controlled. Here’s a quick breakdown:
    • ISO 100-800: Virtually noise-free images.

Low Light Performance

The a6400 excels in low light conditions. If you often find yourself shooting in dimly lit environments, this camera will not disappoint. Here’s why:

  • Noise Reduction: The camera’s noise reduction technology works effectively to keep grain at bay, ensuring your low-light shots are as clean as possible.
  • Bright Lens Options: Paired with a fast lens, the a6400’s low light performance is further enhanced. Lenses with a wide aperture (e.g., f/1.8) allow more light to hit the sensor, resulting in brighter and clearer images.

In summary, the Sony a6400’s performance and image quality make it a fantastic choice for photography enthusiasts. Whether you’re shooting fast action, vibrant landscapes, or portraits in low light, this camera delivers top-notch results every time.

Video Capabilities

The Sony a6400 isn’t just a great camera for photography; it excels in video production as well. This camera is a solid choice for beginners looking to dip their toes into videography. Here’s why.

4K Video Recording

The Sony a6400 offers impressive 4K video recording abilities. Here’s what you can expect:

  • Image Detail: The 4K footage is crisp, with excellent color accuracy and minimal noise. Whether you’re shooting landscapes or close-up shots, every detail is captured beautifully.
  • S-Log and HLG: The a6400 supports S-Log2, S-Log3, and Hybrid Log-Gamma (HLG) recording, giving you a broader dynamic range. This is a fantastic feature for those wanting to do color grading in post-production.
  • Limitations: One downside is the 4K recording comes with a slight crop. It’s minor, but something to be aware of if you need the full frame for wide shots. Also, there’s a 30-minute record limit per clip, which may be restrictive for longer projects.

With 4K capabilities, the Sony a6400 delivers video quality that competes with higher-end models, making it a great pick for budding filmmakers.

Slow Motion and High-Speed Recording

If you’re into creating dramatic slow-motion sequences, the Sony a6400 has you covered:

  • Full HD at 120 fps: The camera can shoot Full HD (1080p) video at up to 120 frames per second. This allows you to create slow-motion videos with smooth, fluid motion.
  • Slow Motion Detail: The 120 fps recording retains excellent detail and minimizes motion blur, giving your slow-motion shots a professional look.
  • Playback Options: You can slow the footage down to 24 fps or 30 fps in your editing software, effectively creating a 4x or 5x slow-motion effect.
  • Creative Possibilities: Think of the action shots you can capture – a skateboarder nailing a trick, a dancer’s graceful moves, or even water splashing in slow motion. It opens up a world of creative possibilities.

With these high-speed recording options, the a6400 lets you get creative with your videos, adding a dynamic flair that keeps your audience engaged.

The Sony a6400’s video capabilities make it a superb choice for any aspiring videographer. Whether you’re shooting stunning 4K footage or experimenting with slow motion, this camera provides the tools you need to create impressive video content.

Battery Life and Connectivity

When choosing a camera, battery life and connectivity are two crucial aspects to consider. Let’s explore how the Sony a6400 fares in these areas.

Battery Performance

The Sony a6400 is equipped with a rechargeable NP-FW50 battery. On a full charge, you can expect to capture approximately 360 shots when using the LCD screen and around 410 shots with the viewfinder. This should be more than sufficient for casual outings and short photography sessions.

Power-Saving Features:

  • Auto Power Off: The camera automatically turns off after a set period of inactivity to preserve battery life. You can customize this setting to match your usage pattern.
  • Airplane Mode: Disables wireless functions like Wi-Fi and Bluetooth to save power, especially useful when these features aren’t needed.
  • EVF/LCD Auto Switch: The camera switches between the electronic viewfinder and the LCD screen based on proximity sensors. This means the LCD only lights up when you’re not looking through the viewfinder, conserving energy.

Despite its compact size, the Sony a6400’s battery life is decent. However, for extended sessions or trips, it’s a smart idea to carry a spare battery or two.

Connectivity Options

The Sony a6400 offers a range of lens options and compatibility that make it a versatile choice for beginner photographers. Whether you’re sticking with the kit lenses or exploring third-party options, you’re sure to find something that fits your needs.

Kit Lenses

When you purchase the Sony a6400, you often have the option to buy it with a kit lens. These lenses are designed to provide a good starting point for beginners and cover a variety of shooting scenarios.

Common Kit Lenses:

  • 16-50mm f/3.5-5.6 OSS (Optical Steady Shot): This is a compact, lightweight lens that offers a versatile zoom range, making it perfect for everyday photography. From wide-angle shots to moderate telephoto, it’s a solid all-rounder. The built-in Optical SteadyShot helps reduce camera shake, ensuring clearer images.
  • 18-135mm f/3.5-5.6 OSS: This lens provides a broader zoom range, making it ideal for those who want more flexibility without carrying multiple lenses. From landscapes to portraits, this lens covers it all. The image stabilization feature ensures crisp images, even at longer focal lengths.

Performance-wise, these kit lenses offer good image quality with decent sharpness and contrast. They also focus quickly and quietly, which is beneficial for both photography and video recording. While they may not match the quality of higher-end lenses, they are an excellent starting point for any beginner.

Third-Party Lenses

One of the great things about the Sony a6400 is its compatibility with a wide range of third-party lenses. This opens up a world of possibilities, allowing you to tailor your equipment to fit your specific needs and budget.


The Sony a6400 uses the E-mount system, which is widely supported by many lens manufacturers. This means you’re not limited to Sony-branded lenses. Brands like Sigma, Tamron, and Rokinon offer high-quality lenses that work seamlessly with the a6400.

Variety of Options:

Here are some popular types of third-party lenses you might consider:

  • Prime Lenses: These lenses have a fixed focal length and are known for their sharpness and low-light performance. A great example is the Sigma 30mm f/1.4, which is perfect for portraits and low-light photography.
  • Macro Lenses: If you’re interested in close-up photography, a macro lens like the Tamron 90mm f/2.8 Macro is an excellent choice. It allows you to capture intricate details with stunning clarity.
  • Zoom Lenses: For those looking for versatility, third-party zoom lenses like the Tamron 28-75mm f/2.8 offer a wide aperture and a flexible focal range, making it suitable for various types of photography—from landscapes to events.

While the Sony a6400 has many strengths, there are also some drawbacks to consider. Knowing these can help you make a more informed decision:

  • Battery Life: The battery life is decent but not exceptional. You can expect around 360 shots per charge when using the LCD screen. For longer shoots or travel, carrying extra batteries is a must.
  • No In-Body Image Stabilization: Unlike some other cameras, the Sony a6400 lacks in-body image stabilization (IBIS). This means you’ll need to rely on lenses with Optical SteadyShot for stability, which can be limiting.
  • Limited Touchscreen Functionality: While the camera has a touchscreen, its functionality is somewhat limited. You can’t fully navigate the menu using the touchscreen, which can be a bit frustrating.
  • Slight Crop in 4K Video: When recording in 4K, the camera applies a slight crop to the image. This might not be a deal-breaker for everyone, but it’s something to be aware of, especially if you need a wider field of view.
  • Micro USB Instead of USB-C: The camera uses a Micro USB port for charging and data transfer, which is a bit outdated. USB-C would provide faster data transfer and charging times.
  • Lack of Weather Sealing: The Sony a6400 does not have weather sealing, making it less ideal for shooting in harsh conditions. If you often shoot outdoors, you’ll need to be extra cautious to protect your gear.

By weighing these pros and cons, you can better determine if the Sony a6400 is the right camera for your needs. Its strengths make it a fantastic choice for beginners, but it’s important to be mindful of its limitations.
