+睿睿的曙光考上了，算是放下了心中的一個重擔。另一個放不下心的是老婆的肝。
+
+看了好幾個禮拜之後，決定不買富士原廠的[XF56mmF1.2 R WR](https://www.fujifilm.com.tw/personal/digitalcamera/xf56mmf12-r-wr/)，決定買入[Sigma 56mm F1.4 DC DN C](https://www.sigma.net.tw/lens/dn/56_14/index.html)。
+
+雖然原廠的銳利度與光圈都比較優秀，但以我的使用情形與極端條件來看，綜合考量下來，優秀的程度與那相差f0.2的光圈並不值得那超過一半的價差。同樣公司貨，數位達人的報價原廠是29500，Sigma則是11800。
+這價差我多買一顆銘匠都還有剩。對！我也買了[銘匠 27mm f2.8](https://ttartisan.com/?AF-Lens/157.html)。
+
+目前有考慮的鏡頭都列在[[想要的鏡頭]]。
