Ukulungiswa kwekhamera kubhekiselele kwinani leepikseli ezinokuthi ikhamera ibambe kwaye igcinwe emfanekisweni, ngokwesiqhelo elinganiswa ngeemegapixels.Umzekelo, iipikseli ezili-10,000 zihambelana nesigidi esi-1 seendawo zokukhanya ezidityanisiweyo zenze umfanekiso wokugqibela. Isisombululo esiphezulu sekhamera siphumela kwiinkcukacha ezinkulu kunye nokuphucula umgangatho womfanekiso. Umzekelo, xa uthatha i-landscape okanye izifundo zabantu, isisombululo esiphezulu sivumela ukubonakaliswa okungcono kweenkcukacha ezintsonkothileyo ezifana nokuthungwa kwamagqabi okanye ukuhonjiswa kwezakhiwo. Nangona kunjalo, izisombululo eziphezulu kakhulu zinokukhokelela kubungakanani beefayile ezinkulu ezidla indawo yokugcina kunye nexesha lokucubungula. Oku kunokudala imiceli mngeni ngexesha lokudutyulwa kwebhetshi kunye nasemva kokuhlelwa; ngoko ke, kubalulekile ukuqwalasela iimfuno zokusetyenziswa xa ukhetha isisombululo esifanelekileyo.
Isisombululo seLens sisebenza njengemetric ebalulekileyo yokuhlola ukucaca okunokuthi ilensi ikwazi ukuhambisa kwisixokelelwano sekhamera, esoloko ibalwa ngeeperi zelayini ngobude (LP/PH) okanye iperi yelayini ye-angular ngemilimitha (LP/MM). Uyilo lwelensi lubandakanya izinto ezahlukeneyo ze-optical, nganye ichaphazela umgangatho womfanekiso obangelwayo. Izisombululo zelensi eziphezulu zenza ukuba kuthathwe okubukhali kunye neenkcukacha ngakumbi yikhamera. Kwiimeko ezisebenzayo ezifana nokufota iziganeko zezemidlalo okanye izifundo ezihamba ngokukhawuleza, iilensi ezikumgangatho ophezulu zinciphisa ngempumelelo i-blur motion kunye nokuphucula izinga lokuphumelela lokubamba. Ngaphaya koko, izinto ezinjengokuhamba kakuhle kokuhanjiswa kokukhanya, ulawulo lokuphambuka kwechromatic, amanyathelo okulawula ukubonakaliswa okubandakanya ii-anti-reflective coatings ngamacandelo abalulekileyo aphembelela ukusebenza kwamehlo ngokubanzi.
Ukusebenzisana phakathi kweekhamera kunye neelensi kubalulekile; baxhomekeke omnye komnye ukumisela umgangatho womfanekiso uwonke. Ukukwazi kwekhamera ukurekhoda ulwazi kuxhomekeke ngokupheleleyo kwizinto ezithunyelwa kwilensi eqhotyoshelweyo; ngoko ke amandla ayo aphezulu akanako ukudlula le lens ibonelela ngayo.
Ke ngoko, xa ufumana izixhobo zokufota kubalulekile ukuba uqinisekise ukuhambelana neziphumo ezisebenza kakuhle. Xa ukhetha izixhobo ezinesisombululo esiphakamileyo kubalulekile ukuba ungagxili nje kwiinkcukacha zezixhobo zakho kodwa nakwindlela iilensi ezihamba nazo ezizilungele ngayo ukuze uphucule ukusebenza kwenkqubo iyonke. Ukongeza, kwaneelensi ezisandula ukuyilwa eziqhayisa nge-optics egqwesileyo enezigqibo eziphezulu ngegama zifuna iikhamera ezihambelanayo ezikwazi ukusebenzisa ngokupheleleyo ezi zibonelelo ukuze wonke umshicileli we-shutter ubambe ubunzulu bokwenyani kwimifanekiso yomlinganiswa okanye imiboniso yendalo.
Elokuqukumbelayo—nokuba ngaba uphonononga ubuchwephesha bokufota okanye usebenziso nje oluqhelekileyo—uvavanyo oluthelekisayo lweempawu zohlobo olwahlukileyo luya kunceda abasebenzisi ekwenzeni ukhetho olunolwazi oluya kuthi ekugqibeleni lutyebise amava abo okufota ngelixa befumana iziphumo ezinqwenelekayo.
