为什么适马30 1.4拍出来的照片很糊

把套头换了刚买的适马30 1.4 发现拍的照片很糊，稍微放大一些就糊了，比我那套头拍的照片清晰度都差。是我那里没设置好还是怎么个回事。比如对焦同样5米外的物体，套头放大了还是比较清晰的，适马的稍微放大一些就糊了……



我传个样子 大佬帮忙看一下
这个链子离我大概一米多

我截了一个局部
如果用套头拍这么近 放大也不会这样啊

还有是6400+30 1.4

有大佬说估计是光圈大了 或者没对到焦，我今天设置的点对焦，绝对对上焦了。就第一张那个云我拍了n张都是放大一些就糊了。
我今天又去试了下，还是那样 稍微放大就是糊的 。我也用这个适马镜头拍了几百张，每张都是这样的，，，，，，下面我找几个
下面是6400+ 适马30 1.4

用着产生一种错觉 ，甚至觉得黑卡1代的画质都比这个头要好 ，拍出来的没有一张不糊 ，服了。
