We already listed pros and cons of each model. However, you may also find useful to look at their common strengths and weaknesses shown side-by-side.

Screen

Sony ZV-E1 and Pentax K-S2 have 3.0" Fully Articulated screens with 1,037k dot and 921k dot resolutions respectively. Fully articulated screen makes cameras selfie and vlogger friendly and generally very useful for video shooting. Sony ZV-E1 also features touchscreen which has advantages such as easy menu navigation, intuitive controls, quick setting adjustment and most importantly a Touch-to-Focus functionality allowing users to select a specific point on the screen where they want the camera to focus. This feature can be helpful for achieving precise focus in both photo and video recording.

Optical (pentaprism) Viewfinder on Pentax K-S2

Pentax K-S2 has a built-in Optical (pentaprism) viewfinder. It has a 100% coverage and 0.95x (0.63x 35mm equivalent) magnification. There is no built-in or optional viewfinder available on Sony ZV-E1.

Sony ZV-E1 features a 12.1 megapixel Full Frame BSI-CMOS sensor with dimensions of 35.6 x 23.8 mm and a total area of 847.3 mm². Its native ISO range is 80 - 102,400 and expands to 40 - 409,600 in boosted mode. Pentax K-S2 features a 20.12 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 - 51,200.

Sony ZV-E1 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 ZV-E1 is equipped with BIONZ XR processor and can take pictures up to 4240 x 2832 resolution. Pentax K-S2 is equipped with PRIME MII processor and can take pictures up to 5472 x 3648 resolution. It can also take pictures with lower resolution like 4224 x 2816, 3072 x 2048, 1920 x 1280 with 3:2 aspect ratios.

Lens Mount

Sony ZV-E1 has Sony E lens mount and Pentax K-S2 has Pentax K_AF2 lens mount. Due to Full Frame sensor in Sony ZV-E1 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. Due to APS-C sensor in Pentax K-S2 its crop factor 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 Pentax K-S2

There is no optical low-pass filter (OLPF), also known as an anti-aliasing filter, in front of the sensor on Pentax K-S2. 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

The cameras have a built-in in-body image stabilization (IBIS) (5 stops of compensation in Sony ZV-E1). This means that you are still getting vibration reduction when cameras are 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 5 802.11ac/b/g/n 2.4/5 GHz on Sony ZV-E1) 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.

Bluetooth on Sony ZV-E1

Sony ZV-E1 has a built-in Bluetooth which lets you to connect the camera to a smartphone or a dedicated remote control device. This allows you to remotely trigger the camera, adjust settings and controls remotely through a paired mobile app. While Wi-Fi is generally faster for transferring larger files, Bluetooth can be used for small, selective transfers, it can provide real-time information about your camera's battery status, memory card capacity, and other key settings directly on your paired smartphone or smartwatch.
