Ngụkọta mmụba = ebumnobi ebumnobi * dijitalụ na-ebuli elu
Ngosi anya lens ebumnobi = Nnukwu ebumnobi oghere oghere * Ngosi anya oghere
Ngosipụta dijitalụ = nha nleba anya * 25.4/CCD nha diagonal ebumnuche
Nha diagonal ebumnuche CCD: 1/3" bụ 6mm, 1/2" bụ 8mm, 2/3" bụ 11mm
Ọmụmaatụ: oghere 0.7X - 4.5X nwere 1/3" CCD na ihe nleba anya 14"
Nbuli elu dijitalụ: 14 * 25.4 / 6 = 59.3X
Ngụkọta mmụba: (0.7X - 4.5X) * 59.3=41.5X - 266.9X
Mgbe ahụ, dị ka nhazi nke dị n'elu, a na-emezigharị mkpokọta akụrụngwa a n'etiti 41.5X na 266.9X.
