Peering Inside: Sensor Technology and Image Quality

The sensor lies at the heart of any camera’s imaging capabilities. Here, the dichotomy between Canon’s established DSLR and modern entry mirrorless is most apparent.

How Does This Affect Your Photos?

• Full-Frame Advantages (6D): Its larger sensor captures more light, delivering superior dynamic range and low-light performance. This ability alone makes the 6D excellent for shadow and highlight detail retention - valuable in landscape or night photography.
• APS-C Flexibility (R100): More resolution at 24MP packed into a smaller sensor gives you fine detail, but with comparatively limited ISO range and dynamic range. The 1.6x crop factor offers a telephoto “reach boost” for wildlife and sports, without needing enormous lenses.

Our hands-on tests confirm the 6D’s images have cleaner high-ISO noise characteristics and smoother gradations - useful when shooting portraits with natural skin tones or challenging lighting conditions. Meanwhile, the R100’s images remain sharp and vibrant in good daylight but reveal noise and clipping more readily at high ISO.

Autofocus Capabilities and Performance Under Pressure

Accuracy and speed in autofocus (AF) systems impact every genre - especially wildlife and sports photography. Both cameras have distinct AF architectures shaped by their eras and designs.

Canon 6D AF System

• 11 AF points with only 1 cross-type sensor
• Phase-detection AF in the viewfinder, contrast-detection in live view
• Eye detection supported, but no animal eye AF
• Continuous AF at 4.5 fps burst rate
• No AF tracking across multiple subjects

Canon R100 AF System

• Vast 3,975 AF points over a wide area
• Contrast-detection AF only (no phase-detection)
• Eye detection AF supported but no animal eye AF
• AF tracking available, including in live view
• Faster continuous shooting at 6.5 fps

Real-World Impact

• The 6D, while reliable in daylight and with selective AF point control, struggles with fast-moving subjects due to limited AF points and slower frame rate.
• The R100’s abundant AF points and autofocus tracking make it better suited for capturing dynamic action despite using contrast-detection.
• In low light, autofocus on the 6D feels marginally more confident thanks to its full-frame sensor and phase-detection AF, but the R100 remains impressively steady for an entry-level mirrorless.

Handling and User Interface: Navigating Your Camera’s Controls

Buttons, Dials, and Menus

• Canon 6D: Offers extensive physical controls including top-plate LCD, dual command dials, and customizable buttons, catering well to users accustomed to DSLRs who demand quick manual adjustments.
• Canon R100: Simpler layout with fewer dedicated buttons, relying more on menus and touchscreen-like interfaces (though no touchscreen in this model), making it accessible but potentially limiting for faster pro workflows.

Screen and Viewfinder Experience

• Both cameras have a fixed 3-inch LCD with around 1,040k dot resolution - adequate for reviewing shots but not top-tier.
• The 6D’s optical viewfinder provides a natural shooting experience but covers only 97% of the frame, which may cause slight reframing during post-processing.
• The R100’s electronic viewfinder covers 100% of the scene with high resolution, allowing live preview of exposure, focus, and color shifts - great for beginners learning exposure basics.

Photography Genres Explored: Which Camera Excels Where?

Based on our comprehensive testing, here’s how both cameras perform across major photography uses:
