#现在微单相机还在拼对焦点数量吗?##长文创作激励计划##头条创作挑战赛#
The focusing ability of digital cameras has historically been based on system sophistication, not the number of focus points, although the number of focus points is an important indicator of a camera's focusing ability.
However, the development of mirrorless cameras on the market has long gone beyond the stage of simply spelling the number of focus points, although the number of focus points is still an important indicator of the performance of the camera's focusing system, but the design of modern mirrorless cameras and consumer demand have shifted to a more comprehensive and intelligent focusing system.
1. Quality and efficiency of focusing system:
• The combination of Phase-Detection Focus (PDAF) and Contrast-Detection Focus (CAF) allows mirrorless cameras to provide fast and accurate focusing performance during high-speed continuous shooting and video recording.
• All-pixel dual-core CMOS AF (a technology used by Canon in its EOS R series) allows every pixel to participate in focusing, improving focusing speed and accuracy.
2. Focus area and coverage:
• The development of camera technology, especially the upgrade of the sensor and focusing system, has enabled many modern mirrorless cameras to achieve a wide coverage of the focus area, almost all over the entire sensor, which allows for greater possibilities and flexibility when composing, and the photographer does not need to reframe the picture or rely on focus locking.
3. Intelligent and predictive focusing:
• The most obvious aspect of the mirrorless camera focusing system upgrade is intelligence, where artificial intelligence and machine learning algorithms are applied to the focusing system, enabling the camera to identify and track specific subjects, such as faces, eyes, cars, or animals.
• Predictive focus predicts the trajectory of moving objects and adjusts focus in advance to ensure crisp images are captured at critical moments.
4. Customization and user interface:
• The advanced mirrorless camera offers a wealth of customization options, allowing photographers to adjust focus settings based on the shooting scene and personal preferences.
• The user interface has become more intuitive, making it easier to adjust focus settings.
5. Video focusing performance:
• With the popularity of video shooting, the video focusing performance of mirrorless cameras has become more and more important, including smooth focus transitions and continuous autofocus.
6. Comprehensive performance:
• The number of focus points is only one part of the performance of a focusing system, modern mirrorless cameras emphasize the overall focusing experience, including speed, accuracy, coverage, intelligent tracking, and video performance.
So, while the number of focus points is still an important consideration, the competition for modern mirrorless cameras has shifted to the overall quality and user experience of focusing systems. Consumers and professionals alike consider all aspects of the focus system, not just the number of focus points, when choosing a camera. Manufacturers are also innovating to improve focusing performance by introducing advanced technologies and algorithms to meet different scenes and shooting needs.
