Understanding the fundamental differences in sensor design drastically impacts your choice. Here’s a detailed sensor spec comparison:

Canon EOS R5:

• Sensor Type: Full Frame CMOS
• Dimensions: 36x24mm
• Resolution: 45MP (8192x5464)
• Max ISO: 51200 (native), 102400 (boosted)
• Anti-aliasing filter: Yes

Fujifilm GFX 50S II:

• Sensor Type: Medium Format CMOS
• Dimensions: 44x33mm
• Resolution: 51MP (8256x6192)
• Max ISO: 12800 (native), 102400 (boosted)
• Anti-aliasing filter: Yes

The 1.7x larger medium format sensor in the GFX 50S II delivers a substantial boost in sensor area, offering inherently higher dynamic range and shallower depth of field capabilities. The 51MP sensor yields superior pixel-level detail, which is particularly beneficial in landscape or commercial studio work demanding ultimate image quality.

Conversely, the Canon R5 provides a slightly lower resolution but impressively high pixel density, delivering excellent sharpness with more manageable file sizes and faster processing. Canon’s DIGIC X processor enhances noise reduction and dynamic range across a wider ISO range, especially useful for low-light scenarios.

In my tests, both cameras produced exceptional image detail. However, the GFX 50S II's medium format sensor revealed better tonal gradation and highlight retention in landscape scenes, whereas the Canon R5 excelled in versatility and high-ISO performance under practical shooting conditions.

The User Interface: Screen and Viewfinder Excellence

Your interface experience can influence shooting enjoyment and efficiency. Both cameras offer electronic viewfinders and LCD screens:

• Canon EOS R5: 3.2" fully articulating touchscreen (2100k dots), 5.76M-dot OLED EVF covering 100% frame at 0.76x magnification
• FujiFilm GFX 50S II: 3.2" tilting touchscreen (2360k dots), 3.69M-dot OLED EVF with similar coverage and 0.77x magnification

The R5’s fully articulating screen is highly practical for vloggers, macro shooters, or photographers working at awkward angles. The touch responsiveness felt snappy and accurate in my use. The Fuji’s tilting screen, while sharper resolution-wise, lacks full articulation, which may limit some creative framing options.

The R5’s EVF impresses with ultra-high resolution and minimal lag, ideal for fast-paced action. The GFX EVF is excellent for static or deliberate compositions, exhibiting crisp contrast and accurate color but sometimes feels less fluid when tracking moving subjects.

Autofocus Precision and Burst Performance

Fast, reliable autofocus is crucial whether shooting wildlife, sports, or portraits. Below is a summary of AF specs and shoot rates:

• Canon EOS R5: 1053 AF points (Dual Pixel CMOS AF II with Phase Detection), Eye & Animal AF, 12 fps mechanical shutter continuous shooting
• Fujifilm GFX 50S II: 425 contrast-detection AF points (no phase detection), no animal eye AF, 3 fps continuous shooting

The Canon EOS R5’s autofocus system is industry-leading, combining an expansive AF point spread with high-speed phase detection and AI-driven eye and animal tracking. During my tests in fast-moving environments like soccer matches and wildlife photography, the R5 rarely lost focus, even with erratically moving subjects.

The GFX 50S II leans towards deliberate composition rather than speed. Its contrast-detection AF system, though precise for static subjects and studio work, is slower and slightly less accurate in continuous autofocus modes. The 3 fps maximum shooting rate lacks ideal burst capacity for action photography.

Real-world note: If you prioritize speed and tracking accuracy, especially in dynamic conditions, the Canon R5 has a clear advantage.
