Iilensi zokugxila ezizinzileyoZinobude obungaguqukiyo befocal kunye nesakhiwo esilula se-optical, ngaloo ndlela zinomgangatho ophezulu we-optical kwaye zisetyenziswa kakhulu ekufoteni. Kwifoto yasebusuku, iilensi zefocal eziguquliweyo zikwasisixhobo esisetyenziswa kakhulu ngabafoti.
Zithini iingenelo zokusebenzisa ilensi egxile kwimifanekiso yasebusuku? Makhe sijonge.
1.Imbobo enkulu ivumela ukukhanya okungakumbi ukuba kungene
Xa kuthelekiswa neelensi ze-varifocal, iilensi ezigxile kwi-fixed focus zihlala zine-aperture enkulu, nto leyo evumela ukuba zibambe ukukhanya okungakumbi ngexesha elifanayo, enye yezona nzuzo zazo ziphambili.
Ingakumbi kwiimeko eziphantsi kokukhanya, ukusebenzisa ilensi yokugxila ezinzileyo kunokunciphisa ingxolo ngempumelelo, kuphucule umgangatho womfanekiso, kwaye kuvelise iinkcukacha ezincinci. Ngaphezu koko, ukwanda kokungena kokukhanya ngenxa yokuvula okukhulu kunceda ekunciphiseni ukufiphala komfanekiso okubangelwa kukushukuma kwekhamera ngexesha lokudubula ngesandla.
2.Ukusebenza kakuhle komgangatho womfanekiso
Iilensi zokugxila ezizinzileyo zinesakhiwo esilula kunye noyilo olujolise ngakumbi kwi-optical, oluhlala luvumela ulawulo olungcono lwe-aberrations (ezifana ne-chromatic aberration, i-distortion, i-field curvature, njl.njl.), ngaloo ndlela zibonelela ngeziphumo zomfanekiso ezicacileyo nezibukhali, ezenza zifaneleke ukufota imigca enzima kunye nokukhanya kunye nomthunzi kwimiboniso yasebusuku.
Kwimifanekiso yasebusuku, olu mgangatho womfanekiso ubalaseleyo lubaluleke kakhulu kuba ukukhanya kufiphele ebusuku, kwaye nesiphoso esincinci siya kubonakala kumfanekiso. Emva kokuthatha iifoto, abafoti badla ngokufuna ukwandisa iifoto ukuze bahlole iinkcukacha, nto leyo eyenza ukuba umfanekiso ube bukhali kakhulu.

3.Incinci kwaye ilula, kulula ukuyiphatha
Iilensi zokugxila ezizinzileyozihlala zincinci kwaye zikhaphukhaphu, nto leyo ezenza zifaneleke ukufotwa ngesandla esiphathwayo kwaye zilungele ukufotwa ngaphandle okanye kokuhambahamba. Umzekelo, xa ufota imifanekiso yasezitalatweni ebusuku, apho kufuneka khona ukuhamba ixesha elide, olu ncedo lokuthwaleka luyabonakala.
Kubafoti bezithombe zasebusuku, iilensi ezikhaphukhaphu nezincinci zinokunciphisa umthwalo wazo wokuthwala kwaye zivumele ukuba zibe bhetyebhetye ngakumbi xa zifota kwiindawo ezahlukeneyo nakwiindawo ezahlukeneyo.
4.Ukusebenza okuguquguqukayo, okufanelekileyo kwisakhiwo sobuchule
Nangona iilensi ezigxile kwi-fixed focus zingaguquguquki njengeelensi ze-zoom ngokutshintsha ubude be-focal, ubude be-focal obugxilileyo bunyanzela abafoti ukuba bacinge nzulu malunga nokwakheka kunye nomxholo ngokubanyanzela ukuba batshintshe indawo yabo ukuze batshintshe ifreyimu.
Kwimifanekiso yasebusuku, ngokuhlala ujikeleza kwaye ulungisa indawo yokudubula kunye ne-engile, ungathatha ngcono utshintsho ekukhanyeni nasemthunzini kunye neengqimba zendawo ebusuku, udale imifanekiso enobuchule ngakumbi.

5.Ukusebenza kweendleko eziphezulu
Xa kuthelekiswa neelensi ze-varifocal,iilensi zokugxila ezizinzileyongokubanzi zifikeleleka lula. Neelensi zobuchwephesha ezizinzileyo ezikumgangatho ophezulu zibonelela ngomgangatho womfanekiso ongcono kakhulu kuneelensi ze-varifocal ezikuluhlu lwamaxabiso afanayo. Kwabafoti abasaqalayo abanebhajethi encinci, iilensi zokugxila ezizinzileyo ezikumgangatho wokuqala ziyindlela entle, zibonelela ngomgangatho womfanekiso olungileyo ngexabiso eliphantsi, zibonelela ngexabiso elihle kakhulu lemali.
6.Ifanelekile ukudubula kwiimeko ezithile
Iilensi ezigxile kwi-fixed focus zilungele kakhulu iintlobo ezithile zeefoto zasebusuku, ezifana neefoto ze-portrait kunye ne-landscape. Kwifoto ze-portrait zasebusuku, i-aperture enkulu kunye nobunzulu obungaphantsi kwebala lelensi egxile kwi-fixed focus zinokugqamisa umxholo, zifiphaze izibane zangasemva, kwaye zigcine ubukhali ebusweni bomntu, nto leyo ekhokelela kwiifoto zobugcisa ngakumbi.
Kwimifanekiso yasebusuku, ilensi yokugxila ebanzi eqinisiweyo ene-aperture enkulu inokubamba imiboniso yokukhanya kunye neenkcukacha ezingaphezulu, okwenza umfanekiso ube mhle kwaye ube nobukhulu obuthathu.
Iilensi zokugxila ezizinzileyo zikwafanelekile ekufoteni iimeko ezithile
Emva kokuqonda iingenelo zeiilensi zokugxila ezizinzileyoKwimifanekiso yasebusuku, kulula ukubona ukuba kutheni ziye zaba sisixhobo esithandwayo kubafoti abafota imifanekiso yasebusuku. Nangona zingaguquguquki kangako ngokwemigama yobude befocal njengeelensi ze-varifocal, iilensi ezigxile kwi-fixed focus ziye zaba zithandwa kakhulu ngabafoti ngenxa yomgangatho wazo ophezulu womfanekiso kunye nokusebenza kwazo.
Iingcinga Zokugqibela:
Ngokusebenzisana neengcali eChuangAn, zombini uyilo kunye nokuveliswa kulawulwa ziinjineli ezinobuchule obuphezulu. Njengenxalenye yenkqubo yokuthenga, ummeli wenkampani unokuchaza ngokweenkcukacha ulwazi oluthile malunga nohlobo lwelensi ofuna ukuyithenga. Uthotho lweemveliso zelensi zikaChuangAn zisetyenziswa kwiintlobo ngeentlobo zezicelo, ukusuka ekujongeni, ukuskena, iidrone, iimoto ukuya kumakhaya akrelekrele, njl. IChuangAn ineentlobo ngeentlobo zeelensi ezigqityiweyo, ezinokutshintshwa okanye zenziwe ngokwezifiso ngokweemfuno zakho. Qhagamshelana nathi ngokukhawuleza.
