性能表现
最让人上瘾的是它的高感。ISO 12800下画面干净得不像话,这在我们的数据库里就是顶级的存在。759个相位对焦点咬住眼睛不放,拍4K 120帧的升格时也没掉过链子。但真正让我们意外的是那块944万点的取景器,大白天看回放简直是一种享受,完全不像以前索尼的祖传小窗。

竞品对比
跟佳能EOS R6 Mark III比,A7S III的视频规格和散热管理更专业,但佳能的防抖和照片像素更均衡。尼康Z9是全能怪兽,但体积和价格都高一个级别。如果你只拍视频,索尼的镜头群和低光表现是决定性优势。富士X-H2像素高,但那是APS-C画幅,高感完全不是对手。

概述
索尼A7S III就是一台披着相机外壳的专业摄像机。如果你需要一台能拍出纯净画面的视频主力机,它就是标杆。1200万像素听起来像是个笑话,但这恰恰是它在暗光下封神的原因。别指望拿它拍完照片回来大幅裁切,它的灵魂全在视频上。
常见问题
Q: 1200万像素拍照够用吗?
发朋友圈和社交媒体完全够用,但别想大幅裁切或者打印巨幅海报。这机器本质上就是为视频设计的,拍照只是附赠功能。
Q: 真的会过热吗?
会。虽然比上一代好很多,但夏天在户外拍4K 60帧以上,连续录20多分钟就可能触发过热保护。把翻转屏打开,自动关机温度设为高,能缓解一些。
Q: 需要买什么存储卡?
想拍4K 120帧或者All-Intra格式,必须用CFexpress Type-A卡,速度飞快但价格感人。如果只拍普通4K,V90的SD卡也能用,但别买便宜的。
不适合的人群
如果你主要拍照片,或者需要高像素来二次构图,这台机器会让你抓狂。1200万像素在今天确实太少了。出门左转看看索尼A7R系列或者佳能EOS R5,它们才是拍照和视频兼顾的好选择。
最终评价
这就是一台为视频而生的机器。如果你90%的时间都在拍视频,尤其是需要高感和升格的场景,闭眼入。它把视频性能做到了这个价位的极致,那些缺点在纯净的画面面前都可以忍。但如果你想拍照视频兼顾,它不适合你。
