To fold the lens module twice, Samsung used what it describes as low-loss surface coating to minimise loss of light during refraction, and employing a ‘high sensitivity sensor ball guide actuator’. The latter seemingly helped improve image stabilisation even at 10x zoom –

something that traditional lenses and professional cameras also often struggle with.
