Pros & Cons
👍 Pros
- Features a 42.4 MP back-illuminated Exmor R CMOS sensor with gapless on-chip lens design for superior image quality.
- Incorporates a new front-end LSI and an updated BIONZ X processing engine, delivering maximum processing speed.
- Boasts an Advanced Hybrid AF system with 399 focal-plane Phase-detection AF points covering 68% of the image plane.
- Offers 425 contrast AF points, collectively covering 47% of the image area for broad and accurate focusing.
- Achieves 10 FPS continuous shooting with continuous and accurate AF/AE in both mechanical and silent shudder modes.
👎 Cons
- The camera's high megapixel count produces large files, which necessitates ample storage and potentially faster computer hardware for editing.
- While featuring an advanced autofocus system, performance may still be challenged in extremely low light or with highly unpredictable subjects.
- The "maximum processing speed" capability might require specific, high-speed memory cards to fully realize its potential during continuous shooting.
- Users accustomed to simpler cameras might find the extensive feature set and customization options to have a learning curve.
- The 47% contrast AF point coverage, while broad, is still less than the phase-detection coverage, which might impact certain focusing scenarios.
