Nangona ezininzi iinxalenye zekhamera yedijithali zibalulekile, i-lens ingabonakala ibaluleke kakhulu. Ngaphandle kwelensi yekhwalithi, iifoto zakho azikho ithuba lokuba zibukhali kwaye zigqamile. Nangona kunjalo kunokuba kunzima ukucacisa ukungafani okwenene phakathi kwama-lens ngaphandle kokwazi ezinye zeekhamera zeekhamera ngokukodwa iilensi. Oku kunokudideka kakhulu ukuqonda ezinye zeemeko eziqhelekileyo ezisetyenziswe ngeelensi.
Xa uthengela ikhamera, qiniseka ukuba ukhethe uhlobo lensiza oluya kusebenza kakuhle kwimeko yakho ngokufunda ibalulekileyo yegama lekhamera yelenjini.
- Zoom. Abanye abathathi beefoto babhekisela ekutsaleni njengokukhushulwa komfanekiso, ukuvumela umfoto-mfanekiso ukuba adubule isithombe "sokuvala" ngaphandle kokuba asondele kufuphi nesihloko. Nangona kunjalo, inkcazo yangempela yokutsalisa yikhono lokukhangela i-lens ekugqibeleni ubude obude. Ngamanye amagama, i-zoom lens inokudubula i-angle ebonakalayo yombhobho okanye i-telephoto shot or both. Hayi zonke iilensi ezibonelela nge-zoom zoom.
- Utsalane lokubonakala. Utsalane olumandla luyakwazi ukutshintsha ubude belo lensi usebenzisa i-hardware ngaphakathi kwilensi ukuze utshintshe ubude obujoliswe kuyo. Uluhlu lwezobugcisa luyindlela ekhethiweyo yokusondeza, njengoko engathinteli kakubi umfanekiso wesithombe ngenxa yokuthembela kwi-hardware kwilenki ukwenza utshintsho. Utsalane olucacileyo luyinto efunyenwe ngekhamera ezijoliswe kuyo, kunokuba i-DSLRs.
- Ukulondoloza kwedijithi. Ukulondoloza idijithali luhlobo lokusondeza apho isofthiwe ngaphakathi kwekhamera ishintshe ubude obude ngokukhupha umfanekiso. Ngenxa yokwenza udijithali luquka ukwandisa ubukhulu beepikseli, ukuzondeza kwedijithali ngamanye amaxesha kunokuchaphazela kakubi ukubonakala komfanekiso. Xa uthengisa ikhamera, ungagxininisekisi kwidijithali, njengoko abaninzi beefoto banokuphinda benze iindidi ezininzi zetekisi yedijithali kunye nesofthiwe yokuvelisa emva. Naka ingqalelo kwinombolo ye-optical zoom.
- Iilensi eziguquguqukayo. Iiphammethi eziphezulu, ii-DSLR neekhamera ezingenakubuyiselwa, apho iilensi ezahlukeneyo zinika amandla ahlukeneyo. Ngolwazi oluninzi lwe- DSLR lens kunye neekhamera zekhamera ezingenasiphene, ukuzinza komfanekiso kwakhelwe kwilenjini, kunqanda ukuzwakalisa ikhamera nokuphucula umgangatho womfanekiso.
- Ubude obude. Ubude obuphambili bubungakanani bemida ukusuka kwinqanaba le-lens ukuya kwisigxininiso (esona isisitho somfanekiso kwikhamera yedijithali). Iilensi zekhamera ezininzi zedijithali zivelisa uluhlu lwentsimbi kumlinganiselo ophezulu, njengama-25mm-125mm. Isilinganiselo sobude obude ngokuchanekileyo silinganisa i-telephoto kunye ne-angle-angle-capabilities ye-lens kunomlinganiselo we-optical zoom, efana nje nenani elibonisa umlinganiselo phakathi kwe-angle ephezulu kunye ne-telephoto. Ngokomzekelo ongentla ongama-25mm-125mm, kuya kuba nomlinganiselo we-zoom we-5X.
- LCD. Ukuboniswa kwekristal yamanzi (i-LCD) emva kwekhamera yedijithali ingasetyenziselwa ukuseka ifoto, njengefowuni. Nangona kunjalo, gcinani engqondweni ukuba i-LCD ayifumanekanga iifayile ezingama-100% womfanekiso ukuba ikhamera iya kudubula. Ukufihla nge- LCD ngamanye amaxesha kungaba ngama-95% okanye ngaphezulu, kwaye ipesenti ngezinye izihlandlo zibhalwe kwiinkcazo zekhamera. Ngokuqhelekileyo ihambelana nombono ngepensi, kodwa ayifani ngokufanayo.
- Isibuko sokubukela. I-viewfinder ye-optical inikeza umfanekiso ongabonakaliyo, ongabonakaliyo wedijithali womfanekiso wefottoli malunga nokudubula. Nge-end-end-end, iphuzu kunye nokudubula iikhamera, i-viewfinder ye-optical ayixhunyiwe kwi-optical lens - kunoko, ngokuqhelekileyo ngaphezu kwe-lens-oku kuthetha ukuba ayinakufanisa ngqo nomfanekiso i-lensi iya kudubula. Ekugqibeleni, ii-DSLR zekhamera zibophe i- viewfinder optical kwi-optical lens, ukubonelela kwangaphambili umfanekiso ozayo.
- I-viewfinder ye-Electronic (EVF). I-EVF kwikhamera yedijithali yile LCD emncinci eyenza umfoto-mfanekiso ithuba lokumisa ifoto. I-EVF iyimelelo yedijithali yomfanekiso. Ngokomzekelo wokulinganisa umbono ngokusebenzisa i-lens yesithombe sokugqibela, i-EVF ihambelana ngokuchanekileyo kweLCD.
