Iilensi zokugxila ezizinzileyo zithandwa ngabafoti abaninzi ngenxa yokuvula okuphezulu, umgangatho womfanekiso ophezulu, kunye nokuphatheka. Iilensi yokugxila esisigxinainobude obugxininisiweyo obusisigxina, kwaye uyilo lwayo lujolise ngakumbi ekusebenzeni kwamehlo ngaphakathi koluhlu oluthile lwengqwalasela, ekhokelela kumgangatho ongcono womfanekiso.
Ke, ndiyisebenzisa njani ilensi yokugxila esisigxina? Masifunde malunga neengcebiso kunye nezilumkiso zokusebenzisa iilensi ezigxininisiweyo kunye.

Ukusetyenziswa kwelensi yogxininiso ezinzileyo kuneendlela zobuchule, kwaye ngokusebenzisa obu buchule, umntu unokusebenzisa izibonelelo zelensi kwaye athathe iifoto ezikumgangatho ophezulu:
1.Khetha ubude bojoliso obufanelekileyo ngokusekelwe kwindawo yokudubula
Ubude be-lens yogxininiso olusisigxina luzinzile, ngoko ke xa uyisebenzisa, kuyimfuneko ukukhetha ubude bogxininiso ngokufanelekileyo ngokusekelwe kwisihloko kunye nomgama odutyulwayo.
Umzekelo, iilensi ze-telephoto zifanelekile ukudubula izifundo ezikude, ngelixaiilensi ezibanzizikulungele ukudubula imihlaba emikhulu; Xa udubula imixholo ekude, kunokuba yimfuneko ukuba usondele kubo ngokusondeleyo, kwaye xa udubula imiboniso emikhulu, kunokuba yimfuneko ukuhlehla umgama othile.

2.Nika ingqalelo ukuchaneka kokugxila kwincwadana
Ngenxa yokungakwazi kweilensi yokugxila esisigxinaukulungelelanisa ubude obugxininisiweyo, umfoti kufuneka ahlengahlengise ugxininiso lwekhamera ukuqinisekisa ukuba umxholo wokufota ugxininise ngokucacileyo. Ukulungelelaniswa kwengqwalasela kunokufezekiswa ngokusebenzisa imisebenzi yokugxila ngokuzenzekelayo okanye ngesandla.
Ezinye iilensi ezigxininisiweyo azikwazi ukugxila kwi-autofocus kwaye zixhasa kuphela ugxininiso lwezandla. Kuyimfuneko ukuba usebenzise kwaye uhlakulele izakhono ezilungileyo zokugxila ngexesha lokusetyenziswa ukuqinisekisa ukudubula okucacileyo kunye nokubonakalayo kwesifundo.
3.Nikela ingqalelo ekusebenziseni izibonelelo zokuvula indawo enkulu
Iilensi ezigxininisiweyo zihlala zinendawo enkulu yokuvula, ngoko zihlala zithatha iifoto ezicacileyo neziqaqambileyo kwiimeko zokukhanya okuphantsi.
Xa ukudubula, ubunzulu bentsimi kunye nobumnyama obungasemva bunokulawulwa ngokulungelelanisa ubungakanani bokuvula: i-aperture encinci (efana ne-f / 16) inokugcina umfanekiso wonke ucacile, ngelixa i-aperture enkulu (efana ne-f / 2.8) inokudala i-aperture ubunzulu obunzulu besiphumo sebala, ukwahlula umxholo kwimvelaphi.
4.Nika ingqalelo ekuqulunqweni okuneenkcukacha
Ngenxa yobude obungaguqukiyo bokujolisa, ukusebenzisa ilensi yojoliso engatshintshiyo kunokuphucula izakhono zokuqamba, kukuvumela ukuba uqwalasele ngononophelo ulungiselelo lwezinto kunye nokubonakaliswa kwemixholo kumfanekiso ngamnye.
