Viewfinder

Sony Alpha 6700 has a built-in 0.39" Electronic (OLED) viewfinder with 2,359k dots resolution and Sony Alpha 6400 has a built-in 0.39" Electronic viewfinder with 2,359k dot resolution. They both have 100% coverage and 1.07x (0.71x 35mm equivalent) magnification.

Sony Alpha 6700 features a 26.0 megapixel APS-C BSI-CMOS sensor with dimensions of 23.3 x 15.5 mm and a total area of 361.2 mm². Its native ISO range is 100 - 32,000 and expands to 50 - 102,800 in boosted mode. Sony Alpha 6400 features a 24.2 megapixel APS-C CMOS sensor with dimensions of 23.5 x 15.6 mm and a total area of 243.4 mm². Its native ISO range is 100 - 32,000 and expands to 100 - 102,400 in boosted mode.

Sony Alpha 6700 has BSI-CMOS sensor, short for Backside Illuminated Complementary Metal-Oxide-Semiconductor sensor. In traditional CMOS sensors, the wiring and circuitry are located on the front side of the sensor, which can block some of the incoming light. BSI technology flips this design by placing the photosensitive elements (pixels) on the backside of the sensor, allowing more light to reach the pixels. This significantly enhances light sensitivity and improves low-light performance. BSI-CMOS sensors are particularly effective in low-light conditions, as they can capture more light, resulting in brighter and less noisy images. This makes them well-suited for indoor and night photography. BSI-CMOS sensors deliver a higher SNR and reduced cross-talk.

Sony Alpha 6700 is equipped with Bionz XR processor and can take pictures up to 6192 x 4128 resolution. Sony Alpha 6400 is equipped with BIONZ X processor and can take pictures up to 6000 x 4000 resolution.

Lens Mount

Cameras have Sony E lens mount. Due to their APS-C sensor their crop factor (also called lens multiplier) is equal to 1.5x. This means that a 35mm equivalent focal length of the mounted lens will be equal to its actual focal length times 1.5.

No Low-Pass Filter on Sony Alpha 6700

There is no optical low-pass filter (OLPF), also known as an anti-aliasing filter, in front of the sensor on Sony Alpha 6700. This results in a slightly sharper image but may also introduce moiré patterns and aliasing artifacts when photographing subjects with fine, repetitive patterns or details.

In-Body Image Stabilization on Sony Alpha 6700

Sony Alpha 6700 has a built-in 5-Axis Sensor Shift in-body image stabilization (IBIS) with 5 stops of compensation. This means that you are still getting vibration reduction when camera is paired with non-image stabilizied lenses. It also works with lenses with optical image stabilization and in combination can achieve even better compensation.

Built-in Wi-Fi

Cameras have built-in Wi-Fi (Wi-Fi 5 MIMO 2x2 802.11ac/b/g/n 2.4/5 GHz on Sony Alpha 6700, 802.11b/g/n 2.4 GHz on Sony Alpha 6400) which allows to easily transfer photos and videos from the camera to other Wi-Fi-enabled devices, such as smartphones, tablets, printers, or computers. This eliminates the need for cables and allows for quick and convenient media sharing and social media integration. It gives you the ability to control your camera remotely using a smartphone or tablet. This is particularly useful for taking self-portraits, group shots, or capturing images in challenging conditions without having to touch the camera. Firmware updates can also be downloaded and installed wirelessly.
