抓拍小孩拍照手機求推薦！網激推2陸廠「不要iPhone」點名這一台
現在許多人都會用手機拍照記錄生活，有「全職寶媽」網友近日發文，表示自己想買新機紀錄寶寶成長，詢問網友推薦型號。許多人都推薦有原況照片的iPhone手機，但也有人說iPhone拍人像不好看、OPPO拍小孩白白嫩嫩，還有人提到Google的Pixel 系列可以一邊吸引小孩注意一邊拍照。
有網友近日在PTT mobile Comm版以「忙碌的全職媽媽無腦拍照手機」為題發文，表示自己購買新機的預算在3萬以內、不限品牌，主要是用來抓拍嬰兒，以及在空閒時滑短片、網購、處理網銀事務，偶爾也會玩一點手遊。原PO說自己是全職在家帶小孩，希望新手機能讓她隨手抓拍嬰兒也能拍得好看，容量至少要512G，續航能力和充電速度優秀，如果外型也好看就更好。
對於原PO列出的條件，許多網友都推薦iPhone，「女生用iPhone、拍小孩打開原況照片」、「問就是iPhone，你以後會感謝自己有用原況拍照片」、「買iPhone就對了，外界公認的拍照好」。
