实测数据
性能表现
最让我们惊讶的是它在f/1.4全开下的锐度。很多大光圈镜头全开时画面会偏软，但这支适马不会。中心锐度从最大光圈开始就非常扎实，收缩到f/2.8更是锐不可当。散景表现更是它的王牌，在我们的数据库中处于97百分位，绝对的顶级水准。光斑圆润干净，过渡如奶油般化开，完全没有低端镜头的生硬感。自动对焦虽然不是最顶级的，但86百分位的排名也足够优秀，步进马达安静迅速，拍静态人像和扫街绰绰有余。唯一的弱点是光学综合评分只在中游，但这主要是因为没有防抖和焦段单一拖了后腿，单论成像硬素质，它远超这个分数给人的印象。

竞品对比
和佳能RF 28-70mm f/2.8这种顶级变焦比，适马56mm f/1.4在虚化和弱光能力上是碾压级的，毕竟光圈大了整整两档，但代价是完全牺牲了变焦的便利性。如果你只拍人像，适马完胜。如果什么都想拍，那支佳能更全能。另一个有趣的对手是腾龙18-300mm，它是个超级旅游头，方便到极致，但画质和光圈跟适马完全不在一个次元。简单说，要极致画质和虚化，选适马；要拍到和方便，选腾龙。

价格
性价比分析
这支镜头没有官方定价，但根据各渠道数据，价格跨度从430美元到57029美元不等，显然那个高价是某种离谱的捆绑包或者错误标价。正常零售价基本在400到500美元区间，在这个价位上，它的光学素质和f/1.4带来的虚化效果，让原厂镜头看起来像是在抢钱。如果你看到400美元出头的价格，直接下手，这就是APS-C系统里最值得买的人像镜头之一。

概述
适马56mm f/1.4 DC DN是那种你用过一次就回不去的镜头。它用相对便宜的价格，把APS-C人像摄影最核心的两件事做到了极致：刀锐奶化的画质和梦幻的背景虚化。如果你正在用佳能EF-M、索尼E或者尼康Z卡口的APS-C机身，并且想找一支能拍出惊艳人像的定焦，那基本可以停止搜索了。这就是目前这个价位段里，人像镜头的版本答案。
常见问题
Q: 这镜头有防抖吗？
没有。镜头本身不带防抖，所以你需要依赖机身防抖或者保持安全快门。好在f/1.4的大光圈能让你在暗光下用更快的快门速度，很大程度上弥补了没有防抖的不足。
Q: 装在索尼A7系列全画幅机身上能用吗？
能，但相机会强制开启APS-C裁切模式，你只能用到传感器中间的一部分，像素会大幅缩水。这镜头是专门为APS-C机身优化的，装在全画幅上属于浪费，我们不推荐这么干。
Q: 56mm在APS-C上相当于全画幅的多少焦距？
索尼和尼康的APS-C机身是1.5倍裁切系数，等效全画幅约84mm。佳能是1.6倍，等效约90mm。不管哪个，都是非常经典的人像焦段。
不适合的人群
如果你需要一支能拍风景、能抓拍、能应付各种场合的挂机头，这支定焦不适合你。它的焦段固定，视角狭窄，拍大场面风光基本没戏。你应该去看看像腾龙18-300mm或者佳能RF 28-70mm f/2.8这样的变焦镜头，它们牺牲了一些画质和光圈，但换来了你真正需要的灵活性。
最终评价
适马56mm f/1.4 DC DN是一支近乎完美的APS-C人像定焦。它用无可挑剔的锐度和梦幻散景，证明了副厂镜头不仅能打，甚至能越级反杀。除了手动对焦手感和缺乏防抖这两个小遗憾，它在核心成像上几乎没有缺点。对于任何想认真拍好人像的APS-C用户来说，这是一支必入的镜头，我们的数据库和几百位用户的真实反馈都强烈支持这一点。
