The Canon EOS R100 is priced at $599 while the Olympus OM-1 Mark II comes in significantly higher at $1,999. This roughly $1,400 price difference marks a substantial gap in their respective features and intended usage.
Design and Build Quality
The Canon EOS R100 is designed for ease of use and portability, making it suitable for everyday photography. In contrast, the Olympus OM-1 Mark II features a weather-sealed design, rated at IP53, which provides protection against dust and splashes. This ruggedness caters to outdoor photographers who often face challenging conditions, including extreme temperatures down to -10℃. While both cameras are built with quality in mind, the OM-1 Mark II stands out for its durability.
Image Quality and Sensor Performance
The Canon EOS R100 boasts a 24.2MP APS-C CMOS sensor that effectively handles a variety of lighting conditions. On the other hand, the Olympus OM-1 Mark II is equipped with a 20MP stacked BSI Live MOS sensor, which enhances resolution and exhibits low noise. While both sensors are capable of producing high-quality images, the stacked design of the OM-1 Mark II provides superior performance in dynamic situations, making it a better choice for wildlife and action photography.
Autofocus and Shooting Speed
When it comes to autofocus capabilities, the Canon EOS R100 employs Dual Pixel CMOS AF with 143 AF zones, ensuring precise focus for a range of subjects. Conversely, the OM-1 Mark II features Cross Quad Pixel AF with 1,053 focus points, offering 100% high-precision coverage. This advanced autofocus system allows for faster and more accurate focusing, particularly useful in fast-paced scenarios. The Canon’s electronic shutter can achieve 6.5 fps, while the Olympus excels with its processing speed, making it a more suitable option for capturing fleeting moments.
Video Capabilities
The Canon EOS R100 supports 4K video recording at 24p, although it does come with a crop factor. Additionally, it offers Full HD 60p for those preferring to shoot in lower resolutions. In contrast, the OM-1 Mark II provides several computational photography functions that enhance video shooting, including Handheld High Res Shot and Focus Stacking. While both cameras are competent for video, the Olympus offers more advanced features that cater to serious videographers and filmmakers.
Included Accessories and Value

While it is a powerful camera, the lack of additional gear may require extra investment for users.

The Canon EOS R100 is better suited for casual photographers looking for an affordable yet capable camera. It is straightforward, making it an excellent choice for those new to photography. In contrast, the OM-1 Mark II targets professional photographers and enthusiasts who require advanced features and ruggedness for serious outdoor shooting. Its higher price point reflects the quality and capabilities that cater to this audience.
