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

Nikon Z8 has a 3.2" Tilting screen with 2,100k dot resolution and Pentax Optio WG-2 GPS has a 3.0" Fixed screen with 460k dot resolution. Tilting screen makes Nikon Z8 very useful for photography purposes but not so useful for video shooting. Nikon Z8 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.

Electronic (OLED) Viewfinder on Nikon Z8

Nikon Z8 has a built-in 0.5" Electronic (OLED) viewfinder with 3,690k dot resolution. It has a 100% coverage and 0.80x magnification. There is no built-in or optional viewfinder available on Pentax Optio WG-2 GPS.

Nikon Z8 features a 45.7 megapixel Full Frame Stacked CMOS sensor with dimensions of 35.9 x 23.9 mm and a total area of 858 mm². Its native ISO range is 64 - 25,600 and expands to 32 - 102,400 in boosted mode. Pentax Optio WG-2 GPS features a 16 megapixel 1/2.3-inch BSI-CMOS sensor with dimensions of 6.17 x 4.55 mm and a total area of 20.7 mm². Its native ISO range is 125 - 6,400.

Nikon Z8 has Stacked CMOS sensor. The key feature of such sensor is its three-dimensional structure, which consists of multiple layers of semiconductor material and circuitry stacked on top of each other. This allows the sensor to have dedicated layers for image capture and signal processing. This separation allows for faster data readout, reducing rolling shutter effects and enabling high-speed shooting and video recording. It is also more power-efficient.

Pentax Optio WG-2 GPS 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 Z8 is equipped with EXPEED 7 processor and can take pictures up to 8256 x 5504 resolution. Pentax Optio WG-2 GPS can take pictures up to 4288 x 3216 resolution. It can also take pictures with lower resolution like 4288 x 3216, 4224 x 2376, 3216 x 3216, 3072 x 2304, 3072 x 1728, 2592 x 1944, 2592 x 1464, 2048 x 1536, 1920 x 1080, 1024 x 768, 640 x 480 with 1:1, 4:3, 16:9 aspect ratios.

No Low-Pass Filter on Nikon Z8

There is no optical low-pass filter (OLPF), also known as an anti-aliasing filter, in front of the sensor on Nikon Z8. 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 Nikon Z8

Nikon Z8 has a built-in 5-Axis Sensor Shift in-body image stabilization (IBIS) with 6 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 GPS on Pentax Optio WG-2 GPS

Pentax Optio WG-2 GPS has a built-in GPS (Global Positioning System) technology which allows you to automatically tag the location where you took your photos. You can later categorize, organize, and search for photos based on location. This is very useful for travel and outdoor photographers for documenting the locations where images were captured.

Built-in Wi-Fi on Nikon Z8

Nikon Z8 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.

Bluetooth on Nikon Z8

Nikon Z8 has a built-in Bluetooth (version 5) 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.
