Uma ufunda isihloko sethu mayelana nekhamera esanda kwethulwa evela ku-workshop I-Samsung NX1, kufanele ukuthi uqaphele ukuthi ikhamera iqukethe inzwa yakamuva ye-APS-CMOS. Inzwa ingathatha izithombe ezingu-28-megapixel, kodwa into ethakazelisa kakhulu ngayo ukuthi ngenxa yobuchwepheshe bamuva, le nzwa ingaqoqa ukukhanya okwengeziwe.
Ngenxa yenqubo yethusi ene-nanometer engama-65-nanometer, ikhamera ingasebenza kangcono kakhulu ebumnyameni. Lokhu kusho ukuthi ungagcina inani eliphakeme le-ISO njengekhadi lecilongo liphakamisa umkhono wakho, ngoba ngale nzwa ngeke uyidinge. Ukusetshenziswa kwamandla nakho kwehliswe kakhulu uma kuqhathaniswa nenqubo evamile yokukhiqiza esebenzisa ubuchwepheshe be-aluminium engu-180-nm.
Njengoba inzwa engu-28-megapixel APS-C CMOS iyimodeli yakamuva ongayithola futhi yenzelwe i-flagship Samsung NX1, kuyacaca ukuthi wonke amanye amapharamitha nawo azoba phezulu. Inzwa iphinde iphushe imingcele kusivinini sokuskena nokonga amandla.
Kodwa-ke, lokho i-Samsung eyayigxile kukho kakhulu kwakuyinkinga yokuthatha izithombe ezimeni ezingezinhle zokukhanya. Inzwa ihlanganisa ubuchwepheshe be-BSI (i-back-side illuminated), obuhambisa izingxenye zensimbi ngemuva kwe-photo-diode futhi lokhu kubangela ukuthi inzwa ithwebule ukukhanya okwengeziwe. Bathi cishe ngo-30% ukukhanya okwengeziwe uma kuqhathaniswa nobuchwepheshe obudala be-FSI (i-front-side illuminated) obusetshenziswa kuze kube manje.
Ukushintsha indawo ye-diode futhi kusho ukuthi izintambo zensimbi ku-sensor zilungiselelwe kangcono ukuthwebula izithombe ezilandelanayo ngokushesha. Futhi lokho kumphumela wokugcina kusho inani lama-30fps uma uthwebula ividiyo ye-UHD.
