光学变焦夜景看潜望长焦是否配备大光圈(f/2.8以内)和OIS，多数机型长焦在夜间进光量骤降，会自动切回主摄裁切，导致'夜景长焦'实为数码变焦

Unverified夜景表现不只看传感器，长曝光多帧合成算法和光学镜头镀膜同样关键；镜头鬼影/眩光控制差的机型在夜晚拍点光源（路灯、霓虹）会出现明显光斑，需查看实拍样张而非参数82% similarUnverified夜景手持成片率取决于OIS光学防抖+算法多帧合成，认准主摄支持OIS（光学防抖）而非仅EIS（电子防抖）；无OIS的机型夜景需要更长手持时间，糊片率显著上升78% similarUnverified夜间效果核心看光圈值而非分辨率，F1.8及以下大光圈镜头夜视表现明显优于F2.0，配合STARVIS/STARVIS2索尼传感器夜间画面更纯净78% similarUnverified夜景多摄协同看长焦夜拍：多数机型夜间超过2x就强制切主摄裁切，只有配备大底长焦(≥1/2英寸)且支持长焦独立夜景模式的机型，才能在弱光下保持远摄画质75% similar
