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

Canon EOS R100 and Pentax Optio WG-2 GPS have 3.0" Fixed screens with 1,040k dot and 460k dot resolutions respectively.

Electronic (OLED) Viewfinder on Canon EOS R100

Canon EOS R100 has a built-in 0.39" Electronic (OLED) viewfinder with 2,360k dot resolution. It has a 100% coverage and 0.95x (0.59x 35mm equivalent) magnification. There is no built-in or optional viewfinder available on Pentax Optio WG-2 GPS.

Canon EOS R100 features a 24.1 megapixel APS-C CMOS sensor with dimensions of 22.3 x 14.9 mm and a total area of 332.3 mm². Its native ISO range is 100 - 12,800 and expands to 100 - 25,600 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.

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.

Canon EOS R100 is equipped with DIGIC 8 processor and can take pictures up to 6000 x 4000 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 Canon EOS R100

There is no optical low-pass filter (OLPF), also known as an anti-aliasing filter, in front of the sensor on Canon EOS R100. 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.

No Image Stabilization

The cameras do not have image stabilization. On Canon EOS R100 it means that you need lenses with optical image stabilization for vibration reduction. As for Pentax Optio WG-2 GPS nothing can be done.

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 Canon EOS R100

Canon EOS R100 has a built-in Wi-Fi (802.11b/g, 2.4 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.
