When choosing a mirrorless camera, autofocus performance is a critical factor, especially for capturing fast-moving subjects or achieving sharp portraits. The Fujifilm X-T30 II and Panasonic G85 are two popular options with distinct autofocus systems. This article compares their autofocus capabilities to help photographers make an informed decision.

Autofocus System Overview

The Fujifilm X-T30 II uses a hybrid autofocus system combining phase detection and contrast detection. It features 425 autofocus points that cover a significant portion of the frame. Panasonic G85, on the other hand, employs a contrast-detection autofocus system with Depth From Defocus (DFD) technology, offering 49 autofocus points.

Autofocus Performance in Different Scenarios

Autofocus Speed

The Fujifilm X-T30 II generally provides faster autofocus, especially in well-lit conditions, due to its phase detection system. It quickly locks onto subjects, making it ideal for action photography. The Panasonic G85's contrast-detection autofocus is slower but improves with good lighting and contrast-rich scenes.

Autofocus in Low Light

In low-light conditions, the Fujifilm X-T30 II maintains reliable focus thanks to its phase detection points and advanced AF algorithms. The Panasonic G85 may struggle more, as contrast-detection autofocus relies heavily on scene contrast, which diminishes in dim environments.

Autofocus Tracking and Subject Recognition

The X-T30 II offers excellent subject tracking, including face and eye detection, which is highly effective for portrait and wildlife photography. The G85's autofocus system is less advanced in tracking moving subjects but performs adequately in controlled scenarios.

Additional Features and Considerations

Fujifilm's autofocus system benefits from its latest firmware updates, enhancing speed and accuracy. It also features customizable autofocus settings. Panasonic G85's autofocus benefits from DFD technology, which predicts subject movement but can be less accurate with fast or erratic motion.

Conclusion

For photographers prioritizing speed, subject tracking, and low-light performance, the Fujifilm X-T30 II offers a superior autofocus experience. The Panasonic G85 provides a decent autofocus system suitable for general photography but may fall short in fast-paced or challenging lighting conditions. Your choice should depend on your specific photography needs and shooting style.
