Iilensi zemizi-mvelisoziilensi ezisetyenziselwa ngokukodwa ukusetyenziswa kwemifanekiso kwicandelo lemizi-mveliso. Zineempawu ezithile ezithile ezinokuhlangabezana neemfuno zecandelo lemizi-mveliso ukuze zifumane umgangatho kunye nokuchaneka komfanekiso, kwaye ke ngoko zisetyenziswa kakhulu kwiinkqubo zemveliso kunye nemveliso yemizi-mveliso.
Kule nqaku, siza kufunda ngeempawu zomfanekiso weelensi zemizi-mveliso.
Isisombululo esiphezulu kunye nokucaca
Iilensi zemizi-mveliso zinesisombululo esiphezulu nesicacileyo, ezinokubamba iinkcukacha ezincinci kunye nemifanekiso echanekileyo, ukuqinisekisa ukuba umgangatho womfanekiso uyahlangabezana neemfuno zezicelo zemizi-mveliso. Oku kubaluleke kakhulu kwiindawo ezifuna ukubonwa ngokuchanekileyo kunye nokulinganiswa kwizicelo zemizi-mveliso, njengakwicandelo lokuhlolwa nokulinganiswa komgangatho.
Iimpawu ezilungileyo ze-optical
Uyilo kunye nokuveliswa kweelensi zemizi-mveliso kudla ngokuthathela ingqalelo uzinzo kunye nokuhambelana kokusebenza kwe-optical. Umzekelo, ngokuqhelekileyo iyila kwaye iphucule inkqubo ye-optical efanelekileyo kwiimeko ezithile zesicelo, enokulawula ngempumelelo ukuphazamiseka kwe-optical okufana ne-astigmatism kunye ne-chromatic aberration ukuqinisekisa ukuchaneka kunye nokuthembeka kwemifanekiso.
Ikwanayo nokukwazi ukuphinda ivelise imibala ngendlela egqwesileyo kwaye inokubuyisela ngokuchanekileyo umbala wokuqala wento efotweyo ukuqinisekisa ubunyani nokuchaneka kwento leyo. Ke ngoko, ukuchaneka nokuthembeka kwayoilensi yemizi-mvelisoUkuthathwa kwemifanekiso kuqinisekisiwe phantsi kweemeko ezahlukeneyo zokukhanya kunye neemeko ezahlukeneyo.
Iilensi zemizi-mveliso zineempawu ezintle zokukhanya
Uzinzo oluphezulu kunye nokuqina
Iilensi zemizi-mveliso zihlala zifuna ukumelana nokusetyenziswa ixesha elide kunye neemeko ezinzima zendalo, ngoko ke zihlala zenzelwe ukuba ziqine kwaye zihlale ixesha elide, zikwazi ukumelana nobushushu obuphezulu, ukufuma, ukungcangcazela kunye nezinye iimvavanyo zendalo. Uzinzo oluphezulu kunye nokuqina zezinye zeempawu zazo ezibalulekileyo. Oku kuqinisekisa ukuthembeka kunye nokuqina kwelensi kwiindawo zemveliso kunye nemveliso yemizi-mveliso.
Ubomi obude bokusebenza
Iilensi zemizi-mveliso zihlala zisebenzisa izixhobo kunye neenkqubo ezikumgangatho ophezulu, ezineengubo ezikhethekileyo kunye neendlela zokukhusela ukuthintela uthuli, ioyile kunye nezinye izinto ezingcolisayo ukuba zingayichaphazeli ilensi. Zisebenza ixesha elide kwaye zisebenza ngokuzinzileyo, kwaye zifanelekile kwizicelo zokusebenza zexesha elide nezinamandla aphezulu, ukuqinisekisa ukuba ilensi inokusebenza ngokuzinzileyo ixesha elide kwiindawo ezinzima.
Ulawulo lokugxila kunye nokuvula
Iilensi zemizi-mvelisoidla ngokuba nemisebenzi yokulawula ukugxila kunye nokuvula, enokulungisa ubude befocal kunye nobukhulu be-aperture ngokweemfuno ezithile ukuze kufunyanwe isiphumo somfanekiso esifunekayo.
Iilensi zemizi-mveliso ziyakwazi ukuzivumelanisa nokusingqongileyo ngendlela enamandla
Imbobo enkulu kunye nomgama omde wokusebenza
Ukuze zilungelelaniswe neentlobo ngeentlobo zezicelo zoshishino, iilensi zoshishino zihlala zinemingxuma emikhulu kunye nemigama emide yokusebenza, kwaye zinokuzivumelanisa nezinto ekujoliswe kuzo ezinobukhulu obahlukeneyo kunye nemigama.
Igubungela iintlobo ezahlukeneyo zeelensi
Iilensi zoshishino zigubungela iintlobo ngeentlobo zeelensi, kuquka iilensi ezigxile kwingqwalasela esisigxina, iilensi ze-zoom, iilensi ze-macro, njl.njl., ezinokuzivumelanisa neemfuno ezahlukeneyo zesicelo sezoshishino.
Ngamafutshane, uyilo kunye nokuveliswa kweiilensi zoshishinoukugxila ekusebenzeni nasekuqineni, okunokuhlangabezana neemfuno zecandelo lemizi-mveliso zokuchaneka komfanekiso kunye nokuzinza kwaye zisetyenziswa kakhulu kwicandelo lemizi-mveliso.
Iingcinga Zokugqibela:
UChuangAn wenze uyilo lokuqala kunye nokuveliswa kweelensi zemizi-mveliso, ezisetyenziswa kuzo zonke iinkalo zezicelo zemizi-mveliso. Ukuba unomdla okanye uneemfuno zeelensi zemizi-mveliso, nceda unxibelelane nathi ngokukhawuleza.
