Ukuze uyisebenzise, khetha inkcazo yokugxila kwaye cinezela iqhosha le-shutter isigxina uze uvale i-beep (ukuba unomsebenzi osebenze) okanye uqaphele ukukhanya kwesikhombisi ekujoliswe kuyo kwisibuko - mbonakalo . Cinezela inkinobho yokuvala ngokuzeleyo ukuthatha umfanekiso uze uphinde uphendule.
Qaphela ukuba ezininzi iikhamera aziyi kukuvumela ukuthatha isithombe kwimodi yokuShawula kuphela uze i-lens igxile ngokupheleleyo.
Iikhamera zedijithali zinomsila obomvu owenzela i-autofocus enceda ikhamera ifumane ingqalelo kwiimeko eziphantsi zokukhanya. Kwiintlobo ezininzi ze-DSLR, oku kuya kusebenza kuphela kwimodi ye-Single Shot. Kuyafana njalo ukuncedisa iiplanga ezakhiweyo kwiinqwelomoya zangaphandle.
