Unverified为覆盖24-200mm大变焦范围，镜头长焦端最大光圈只有F4.5，暗光和长焦虚化能力受限，属焦段换画质的权衡86% similarUnverified覆盖 24-200mm 的超大变焦比换来了便携性，但长焦端画质（解析力与色差控制）相比同焦段定焦或小变焦比镜头有明显差距，是典型的便利性与画质的权衡86% similarUnverified带长焦（24-200mm等效）的卡片机牺牲了大光圈，长焦端光圈普遍缩到F4.5以上，弱光长焦拍摄画质会明显下降；纯定焦或短变焦机型光圈更大更适合暗光84% similarUnverified大变焦比镜头（如28-300mm、24-240mm）在长焦端和广角端边缘画质明显下降，暗光对焦也慢，追求画质者慎选10倍以上变焦83% similarUnverified变焦倍数越高的卡片机镜头素质和光圈越受限，大变焦机型长焦端光圈通常缩到f/4以上暗光乏力，画质党应选变焦范围克制但恒定大光圈的机型83% similar
