📋 目次
1What sensor size and resolution should I look for in a 4K full-frame mirrorless camera?
A full-frame sensor (36mm x 24mm) paired with at least 24 megapixels ensures excellent image quality and low-light performance. While 4K video is standard, look for models that support 4K at 60fps for smooth motion, and consider 8K recording if you need high-resolution stills or future-proofing.
2Which autofocus systems are best for 4K full-frame mirrorless cameras?
Look for cameras with at least 500 phase-detection points and a hybrid autofocus system for fast, accurate tracking. Models with eye-tracking and subject recognition are ideal for video and wildlife photography, while those with AI-based AF excel in low-light or complex scenes.
3What lens compatibility should I consider when buying a 4K full-frame mirrorless camera?
Ensure the camera uses a widely supported mount like Sony E, Nikon Z, or Canon RF, which offer extensive lens ecosystems. Adapters exist, but native lenses provide better performance. Consider future lens needs, especially if you plan to expand into video or specialized photography.
4How important is in-body image stabilization (IBIS) for a 4K full-frame mirrorless camera?
IBIS is crucial for handheld video and low-light photography, reducing camera shake by 3-5 stops. Look for models with 5-axis stabilization for the best results, especially if you shoot without a tripod or in dynamic environments like events or travel.
5What video features should I prioritize in a 4K full-frame mirrorless camera?
Prioritize 4K at 60fps, log profiles for color grading, and external recording via HDMI for higher bitrates. Look for dual card slots for backup and 10-bit 4:2:2 color depth for professional editing. Also, check for built-in ND filters and good audio inputs if you shoot video frequently.
