The physical design of a camera plays a crucial role in its usability and durability. Both the Sony a6400 and a6600 feature a compact and lightweight design, making them highly portable and convenient for photographers who are constantly on the move. These cameras are well-suited for travel, street photography, and other situations where size and weight are important factors.

However, the a6600 takes it a step further with its robust magnesium alloy construction. This construction enhances the camera’s overall durability, making it more resistant to dust and moisture. With its weather-sealed body, the a6600 offers increased protection, allowing photographers to confidently shoot in challenging conditions such as rain or dusty environments. If you frequently find yourself in rugged outdoor settings or engage in sports photography, the a6600’s sturdier build provides added peace of mind.

Sensor and Image Quality

The image sensor is a critical component of any camera, as it directly affects the image quality produced. Both the a6400 and a6600 incorporate a 24.2-megapixel APS-C Exmor CMOS sensor, which is known for delivering exceptional image quality with excellent detail and dynamic range.

However, the a6600 utilizes an enhanced version of the sensor. This enhanced sensor offers improved color reproduction, ensuring accurate and vibrant color rendering in your photographs. Additionally, the a6600’s sensor excels in low-light performance, thanks to its enhanced sensitivity and noise reduction capabilities. As a result, the a6600 produces cleaner images at higher ISO levels, allowing you to capture stunning photos even in challenging lighting conditions.

Autofocus and Performance

Autofocus performance is a key consideration, especially for photographers who frequently shoot moving subjects or require precise focusing. Both the a6400 and a6600 boast an impressive 425-point phase-detection autofocus system, which covers a wide area of the frame. This extensive coverage ensures fast and accurate subject tracking, enabling you to capture sharp images of subjects in motion.

However, the a6600 takes autofocus capabilities a step further with the inclusion of Real-time Eye AF. This feature, available for both humans and animals, allows the camera to automatically detect and track the eyes of your subjects. Real-time Eye AF ensures that the focus remains sharp on the subject’s eyes, even when they are moving within the frame. This makes the a6600 an excellent choice for portrait photography, as well as wildlife and pet photography.

In terms of performance, the a6600 offers a superior buffer capacity compared to the a6400. The buffer capacity determines how many continuous shots you can capture at high frame rates before the camera’s buffer fills up and slows down. The a6600 has an impressive buffer capacity, allowing you to capture up to 116 JPEG or 46 RAW images in a single burst. In contrast, the a6400 has a slightly lower buffer capacity, with the ability to capture up to 99 JPEG or 46 RAW images in continuous shooting mode. This enhanced performance of the a6600 makes it particularly well-suited for sports, action, or any situation where capturing a rapid sequence of shots is crucial.

Video Capabilities

Both the a6400 and a6600 excel in video recording capabilities, delivering impressive 4K UHD resolution with full pixel readout and no pixel binning. This means that the cameras utilize the full sensor width to capture detailed and high-quality footage, resulting in vibrant videos.

However, the a6600 offers an additional advantage with its built-in 5-axis in-body image stabilization (IBIS). This feature compensates for camera shake, providing smoother and more stable footage, especially when shooting handheld or using non-stabilized lenses. The IBIS system of the a6600 allows for greater flexibility in capturing steady videos, reducing the reliance on external stabilizers or gimbals. This is particularly beneficial for videographers who often shoot in dynamic or fast-paced environments where maintaining stable footage can be challenging.

On the other hand, the a6400 relies on lens-based stabilization, which means that the effectiveness of stabilization depends on using lenses with built-in optical stabilization. While this can still provide stabilization benefits, it may not be as effective or versatile as the in-body image stabilization of the a6600.

Battery Life

Battery life is a crucial consideration for photographers, especially when shooting in remote locations or situations where access to power sources is limited. The a6600 boasts an advantage over the a6400 in this aspect, thanks to its larger NP-FZ100 battery. This higher-capacity battery allows the a6600 to capture approximately 810 shots per charge, providing extended shooting time without the need for frequent battery changes.

On the other hand, the a6400 comes with the smaller NP-FW50 battery, which provides approximately 410 shots per charge when working with the LCD screen or 360 shots when using the viewfinder. While this is still respectable battery life, it may require photographers to carry additional batteries or be mindful of power management during longer shoots or travel situations.


Both the a6400 and a6600 offer a range of connectivity options to enhance your shooting experience and facilitate seamless file transfer and sharing. In addition to the aforementioned Wi-Fi and NFC capabilities, both cameras provide convenient wireless connectivity for transferring images and videos to compatible devices such as smartphones, tablets, or computers.

Furthermore, the cameras support USB connectivity, enabling direct connections to computers or other compatible devices. This feature simplifies the process of transferring files, performing firmware updates, or even enabling tethered shooting, where you can control the camera settings and capture images remotely from a computer.

Both cameras come equipped with a micro HDMI port, allowing you to connect them directly to external monitors or televisions. This feature comes in handy when you need a larger display to review your images or videos in detail or when showcasing your work to a larger audience.

Other Features

Both cameras also offer an external microphone input, which allows for the connection of external microphones. This is particularly valuable for videographers, vloggers, or anyone who requires high-quality audio recording. By using an external microphone, you can achieve better sound clarity and reduce ambient noise, resulting in professional-grade audio for your videos.

It’s worth noting that the a6600 offers a headphone jack, which is absent in the a6400. This allows you to monitor audio in real time while recording videos, ensuring that you capture the desired sound without any unwanted noise or distortion. This feature is especially valuable for videographers or content creators who require precise control over audio quality.


Sony a6400 vs a6600: Is It Worth the Upgrade?

While the a6400 offers a more affordable option without compromising on image quality and autofocus performance, the a6600 provides several notable upgrades, including better weather sealing, enhanced image stabilization, improved battery life, and additional video recording capabilities.

Evaluate carefully wether you need these new features or not, as the a6400 is still a great choice.
