几张南京的远景，奥林巴斯EM10拍摄，另外有几个问题想问。

设备是奥林巴斯EM10MK3，镜头有奥林巴斯14-40f3.5，40-150f5.6和松下20 f1.7定焦。
拍的照片是很满意，有两个疑问
1. 为啥拍出来感觉雾蒙蒙的，是因为空气湿度大吗？可是那天很晴朗看起来不像大雾。还是我拍摄出了问题？和M43底太小有关吗？和我没有遮光罩有关吗？
我要怎样才能拍出不模糊的城市远景
2. 用P档拍出来感觉很模糊，用自动挡感觉不模糊但是发蓝，是因为什么原因？
如果我要用M档来拍应该怎么调比较好，为什么奥巴用M档右下角有个数轴在动？ [img]https://img.nga.178.com/attachments/mon_202008/05/-570ynQ5-1hpmK22T3cSsg-lc.jpg.medium.jpg[/img][img]https://img.nga.178.com/attachments/mon_202008/05/-570ynQ5-2q3vK2fT3cSsg-lc.jpg.medium.jpg[/img]
