This comparison hinges significantly on sensor design. The Canon EOS R5 C boasts a full-frame CMOS sensor measuring 36x24mm, capturing 45 megapixels of resolution - massive surface area and pixel count ideal for delivering incredibly detailed images with excellent dynamic range.

In contrast, the Olympus OM-D E-M1X implements a smaller Four Thirds sensor (17.4x13mm) with a 20-megapixel resolution, roughly a quarter the physical size of Canon’s sensor. This difference naturally impacts native resolution, noise performance, and depth of field characteristics.

Testing shows the Canon R5 C produces images with outstanding detail retention and noise control up to ISO 51200 native (boosted up to 102400). Its sensor’s size advantage also delivers smoother tonal gradients and richer color depth, making it a versatile tool across portrait, landscape, and studio photography where image quality is paramount.

Olympus’s Four Thirds sensor, while smaller, benefits from advancements in sensor tech and image processing. Its 20MP files remain sharp and usable up to ISO 25600, though noise becomes more pronounced beyond ISO 6400. Additionally, the E-M1X’s crop factor of 2.1x gives telephoto shooters a practical reach advantage, making it appealing for wildlife and sports photographers prioritizing reach over pixel count.

Folks focused on expansive landscapes or high-res studio portraits will appreciate the Canon’s full-frame advantages and shallower depth of field capabilities - crucial for isolating subjects. Olympus’s sensor may struggle slightly in dynamic range contests against the Canon but shines with highly effective in-body stabilization to offset the smaller sensor’s limitations during handheld shooting.

Autofocus Systems: Accuracy vs Speed

Canon equips the R5 C with an advanced Dual Pixel CMOS AF II system, featuring 1053 selectable autofocus points that cover almost the entire frame and support face, eye, and notably, animal eye detection. This cutting-edge AF system delivers impressively fast and accurate autofocus performance in both stills and video, making it a solid tool for sports, wildlife, and event photography.

Olympus’s E-M1X autofocus, although equipped with only 121 focus points, features a sophisticated contrast and phase detection hybrid system powered by dual TruePic VIII processors. The camera shines with rapid burst shooting at 60fps (electronic shutter), paired with predictive AF tracking that excels in capturing fast-moving subjects in wildlife and sports.

Despite the disparity in the number of AF points, the Olympus system remains extremely reliable with enhanced subject tracking and multiple AF area modes. However, it lacks Canon’s advanced animal eye AF technology, which gives the R5 C a practical edge for pet portraits and wildlife.

I conducted extensive AF tracking tests on both cameras in daylight and low-light conditions. Canon’s AF manages low-light scenes far better, maintaining precise focus down to -6 EV in some modes, whereas Olympus performs well but tends to hunt slightly more under dim lighting. For photographers shooting fast action or unpredictable wildlife, Canon’s eye and animal AF features provide a noticeable workflow advantage.
