• Resolution: 20 MP (5472×3648 pixels)
• Sensitivity Range: ISO 100–102,400 (expandable to 50–819,200)
• Anti-Aliasing Filter: Yes
• Processor: DIGIC X

Canon’s advanced 20 MP sensor balances resolution with high-speed data throughput and excellent low-light performance. The full-frame dimension provides a large photosite area, enabling superior dynamic range, reduced noise at high ISO, and more effective shallow depth of field control - paramount for portrait, wildlife, and sports image quality.

Fujifilm IS Pro:

• Sensor Type: APS-C CCD (23×15.5 mm)
• Resolution: 6 MP (4256×2848 pixels)
• Sensitivity Range: ISO 100–3200
• Anti-Aliasing Filter: Yes

This 6 MP CCD sensor harks back to the pre-CMOS dominance era, optimized for high-resolution forensic and UV/IR imaging rather than naturalistic color capture. Its smaller sensor size and lower resolution constrain large print usability and cropping flexibility for general photography but serve niche spectral imaging well.

From practical experience, Canon’s sensor significantly outperforms in dynamic range and signal-to-noise ratio. The Fuji’s limited ISO ceiling restricts usability in low light and fast action, while the Canon’s high ISO thresholds support night and sports photography with manageable noise levels.

Autofocus Systems: Speed and Accuracy in Diverse Environments
