📋 目次
1What sensor size should I look for in a mirrorless DSLR camera?
Look for a full-frame (36mm x 24mm) sensor for superior low-light performance and depth of field control, or APS-C (22.5mm x 15mm) for a more compact body and better reach with telephoto lenses. Full-frame is ideal for professional photography, while APS-C suits enthusiasts and travel photographers.
2How does autofocus performance vary between mirrorless and DSLR cameras?
Mirrorless cameras typically use phase-detection autofocus on the imaging sensor, offering faster and more accurate focusing, especially in video. DSLRs use a separate phase-detection module, which can lag slightly. Look for at least 300 phase-detection points for reliable subject tracking in action or sports photography.
3What lens mount should I prioritize based on my needs?
Choose a mount with a wide range of compatible lenses, such as Sony E-mount, Fujifilm X-mount, or Canon RF-mount. Consider future lens availability and whether you already own lenses in the same system. Third-party lenses are often available but may vary in quality and support.
4What video capabilities should I check for in a mirrorless DSLR?
Look for 4K recording at 30fps or higher, log profiles for better color grading, and at least 10-bit internal recording. In-body image stabilization (IBIS) is also valuable for handheld video. Some models offer 8K or higher frame rates, but these may require external recorders for full resolution.
5Is in-body image stabilization worth the extra cost?
Yes, if you shoot handheld or in low-light conditions. IBIS can compensate for camera shake by shifting the sensor, often offering 3-5 stops of stabilization. It works with any lens, unlike lens-based stabilization, and is especially useful for travel, street, or documentary photography.
