iPhone 18 Pro系列今年首度導入可變光圈,成為新機最受矚目的升級之一,不過近期一段拆解影片卻意外掀起另一波討論。知名YouTube頻道Phone Repair Guru拆機時發現,只要將磁鐵靠近相機模組,光圈葉片竟會立刻收合,也讓不少網友好奇,強力磁鐵是否可能干擾這套全新相機系統。
磁鐵影響可變光圈?拆解畫面引熱議
Phone Repair Guru拆解iPhone 18 Pro系列相機模組時,特別研究可變光圈結構。主相機採用6片光圈葉片,提供f/1.48、f/1.8、f/2.8與f/4共4段光圈可調。從磁鐵靠近後,葉片會直接產生動作來看,他推測蘋果可能是透過微型電磁馬達驅動光圈,也就是利用線圈通電產生磁場,再透過內部轉動結構,控制6片光圈葉片開闔。

這段畫面曝光後,也立刻引起網友熱議,有人直呼「那不是要離磁鐵遠一點?但iPhone自己就有MagSafe」,也有人認為,真正需要注意的應該是磁力特別強的磁鐵,並非一般MagSafe配件。
蘋果提醒磁性配件可能影響相機 非針對可變光圈
外媒報導,蘋果其實過去就曾針對磁力配件可能干擾iPhone相機提出警告。根據蘋果官方說明,部分iPhone具備OIS光學影像防震與閉環自動對焦功能,鏡頭內的定位感測器會對磁場產生反應,如果強力磁鐵太靠近,可能造成干擾,甚至讓感測器暫時無法正常運作。一旦受到影響,不只可能降低感測器準確度,也會限制鏡頭可以移動的範圍。雖然相機仍能透過其他方式進行防震拍攝,但OIS與閉環自動對焦的效果就可能無法正常發揮。
蘋果也提醒,部分第三方手機殼、車用支架等配件,可能會在靠近iPhone後置鏡頭的位置使用強力磁鐵或磁性金屬板為了讓相機維持最佳表現,建議避免讓這類磁性配件過度靠近後置鏡頭。不過,值得注意的是,蘋果這段說明只是闡述磁力配件可能干擾iPhone相機,並非是針對可變光圈設計,
不過值得注意的是,蘋果這段官方說明主要是在提醒磁力配件可能干擾iPhone相機的OIS與閉環自動對焦系統,並不是特別針對iPhone 18 Pro系列的可變光圈設計。換句話說,目前只能確認拆解測試中,外部磁場確實會讓光圈葉片產生反應,至於是否會對可變光圈造成實際損壞,現階段仍沒有官方證據證實。
