Electronic (OLED) Viewfinder on Sony Alpha 7 IV

Sony Alpha 7 IV has a built-in 0.5" Electronic (OLED) viewfinder with 3,680k dot resolution. It has a 100% coverage and 0.78x magnification. There is no built-in or optional viewfinder available on Nikon 1 S2.

Nikon 1 S2 features a 14.2 megapixel 1-inch CMOS sensor with dimensions of 13.1 x 8.8 mm and a total area of 115.3 mm². Its native ISO range is 200 - 12,800. Sony Alpha 7 IV features a 33.0 megapixel Full Frame BSI-CMOS sensor with dimensions of 35.9 x 23.8 mm and a total area of 566.4 mm². Its native ISO range is 100 - 51,200 and expands to 50 - 204,800 in boosted mode.

Sony Alpha 7 IV 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.

Nikon 1 S2 is equipped with EXPEED 4A processor and can take pictures up to 4592 x 3072 resolution. Sony Alpha 7 IV is equipped with BIONZ XR processor and can take pictures up to 7008 x 4672 resolution.

Lens Mount

Nikon 1 S2 has Nikon 1 lens mount and Sony Alpha 7 IV has Sony E lens mount. Due to 1-inch sensor in Nikon 1 S2 its crop factor is equal to 2.7x, this means that a 35mm equivalent focal length of the mounted lens will be equal to its actual focal length times 2.7. Due to Full Frame sensor in Sony Alpha 7 IV its crop factor is equal to 1x, this means that a 35mm equivalent focal length of the mounted lens will be equal to its actual focal length.

No Low-Pass Filter on Sony Alpha 7 IV

There is no optical low-pass filter (OLPF), also known as an anti-aliasing filter, in front of the sensor on Sony Alpha 7 IV. 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 7 IV

Sony Alpha 7 IV has a built-in 5-Axis Sensor Shift in-body image stabilization (IBIS) with 5.5 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 on Sony Alpha 7 IV

Sony Alpha 7 IV has a built-in Wi-Fi (Wi-Fi 5, 802.11ac/b/g/n, 2.4/5 GHz) 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.
