Xa uhlengahlengiso lwe-iris, iris ihlala ikwimeko enkulu yokuvula.Kuphela xa iqhosha le-shutter licinezelekile ukukhulula i-shutter, i-aperture iyancipha ngokuzenzekelayo kwi-f-factor, kwaye i-aperture ibuyela kwi-aperture enkulu emva kokuvezwa.
Yintoni ilensi?Ilensi ineminwe emibini kwifilimu nakumabonakude, enye ibhekisa kumacandelo okukhanya asetyenziswa ziikhamera bhanyabhanya kunye neeprojektha ukwenza imifanekiso, kwaye yenziwe ngamalensi amaninzi.Iintlobo ezahlukeneyo zeelensi zineempawu ezahlukeneyo zokubumba.Ukusetyenziswa kwabo kwimodeli yeefoto kubandakanya indlela yokubonakalisa i-optical;eyesibini ibhekisa kumfanekiso oqhubekayo othatyathiweyo ukusuka kumandla-ukuya kumbane-ukucima, okanye icandelo phakathi kwamanqaku amabini adibanisayo , Ekwabizwa ngokuba yi ytterbium.Umnwe omnye kunye neminwe emibini ziingcamango ezimbini ezihluke ngokupheleleyo.Ukwenzela ukwahlula umahluko phakathi kwezi zimbini, enye ibhekisa kwilensi yokubona kwaye ezi zimbini zibhekisa kumfanekiso welensi.
Ilensi ekubhekiselwa kuyo kwifilim nakumabonakude ayisiyo lens ebonakalayo okanye ebonakalayo, kodwa ilensi ethwala umfanekiso kwaye inokwenza umfanekiso.I-lens yiyunithi esisiseko ehlanganisa yonke ifilimu.Iifoto ezininzi zenza umhlathi okanye umboniso, kwaye imihlathi emininzi okanye imiboniso bhanyabhanya.Ngoko ke, i-lens ikwayiyunithi esisiseko yolwimi olubonwayo.Sisiseko sokubalisa kunye nokubonakalisa.Ngaphambi kokufota imisebenzi yefilimu kunye nomabonakude, ilensi ibhekisa kwisimbuku secandelo lemifanekiso ethathwe yikhamera ukusuka ekuqaleni ukuya kuthi xhaxhe;kwi-post-editing, i-lens yisethi yemifanekiso phakathi kwamanqaku amabini okuhlela;kwifilimu egqityiweyo, enye I-lens ibhekisela kwicandelo elipheleleyo ukusuka kwinguqu yangaphambili ye-optical ukuya kwinguqu elandelayo ye-optical.
Umsebenzi oyintloko we-lens kukuqokelela ukukhanya okubonakalisiweyo kwinto ekhanyisiweyo kwaye igxininise kwi-CCD.Umfanekiso oboniswe kwiCCD ujonge phantsi.Isekethe yekhamera inomsebenzi wokuyibuyisela umva, kwaye umgaqo wayo we-imaging ufana neliso lomntu.
Ukuhlelwa kweLens:Ngokwemvelaphi yelensi, ubukhulu becala lens yaseJapan kunye nelensi yaseJamani.Iilensi zaseJapan ubukhulu becala zinokuphinda ziphinde zikwazi ukuphinda ziphinde ziphinde ziphindeke kakuhle zemibala, kwaye iilensi zaseJamani zinembono eyomeleleyo yokubeka umaleko.Kwimarike, iilensi zaseTshayina ngokuthe ngcembe zingena emarikeni, ngakumbi ngenxa yokuba amaxabiso aphantsi.
