Yini Izinombolo ZamaLensi Okuhlunga Ikhamera ashoyo?
Q: Zisho ukuthini izinombolo kuma-lens zoom zoom? Iyini incazelo yensimbi yokusondeza kwekhamera?
A: Ukuqonda ama-lens ekhamera, ikakhulukazi ama-zoom lensiza ye-digital, kungaba inqubo ekhohlisayo. Qinisekisa: Izinombolo ezibalwe ngama-lens zoom zoom ikhamera zibonakala zilula. Isilinganiso se-zoom ye-zoom ye-10X sincane kakhulu, kanti isilinganiso se-zoom sokulinganisa esingu-50X siningana ne-lens zoom enkulu. Futhi ungakwazi ukudubula ibanga elide kakhulu ne-zoom lense enkulu kunalensi encane yokusondeza.
Ngenkathi lezo zincazelo zilula ngokwanele ezithombeni eziyisisekelo, azitsheli lonke indaba. Ukuze uthole izithombe ezicacile ezidingekayo, ukuqonda kangcono ikhamera yokusondeza ikhamera kubalulekile. Qhubeka ufunda ukuze ufunde kabanzi mayelana nama-lens zoom zoom.
Incazelo yokuhlunga kwe-Lens
Izinga lens zoom zoom ikhamera yedijithali ibonisa inani lokukhulisa i-lensi ingaveza. Izinombolo zingase zidideke, noma kunjalo, ngoba abanye abakhiqizi baqokomisa izilinganiso ezahlukene, kufaka phakathi ukusondeza okubonakalayo , ukusondeza kwe-digital , nokusondeza okuhlangene. Gcina lokhu engqondweni lapho usebenza ekuzwiseni ama-zoom lens:
Ukusondeza okubonakalayo kuyisilinganiso sokusondeza esibaluleke kunazo zonke ngoba silinganisa ububanzi obude bokukhanya kwe-lens, ngokusekelwe kokwakhiwa kwangempela komzimba. Njengoba ikhamera idlulisela izakhi zengilazi ku-lens, ubude bokugxila kwe-lens buyishintsha, ukuyibeka ububanzi obude obufunwa ku-lens zoom.
I-zoom yedijithali yedijithali iyinhlangano yokulinganisa ububanzi obude bokuthi isofthiwe yekhamera idala. Esikhundleni sokuhambisa izakhi zomzimba zensiza ukuze zishintshe ubude bokugxila kwe-lens, isofthiwe yekhamera idumisa isithombe njengoba iboniswe kusikrini se-LCD, kudala ukukhohliswa kwe-lens zoom. Ngenxa yokuthi isilinganiselo se-digital zoom sikhulisa isithombe, singabangela ukulahlekelwa ukubukeka esithombeni, ngakho-ke ukusebenzisa i-digital zoom akukhuthazwa ngaphandle kokuthi ungenakho okunye okukhethwa kukho. Ikhamera ye-smartphone ingasebenzisa ukusondeza kwe-digital kuphela.
Abanye abenzi bekhamera basebenzisa leli gama ukuhlanganisa ukusondeza ukuchaza amalensi abo, nakuba lokhu kuyisikhathi esidala. Ukusondeza okuhlanganisiwe kubhekisela kwisilinganiselwa sokusondeza kokubili kokusondeza okubonakalayo nokusondeza kwe-digital okwenziwe ndawonye.
Ukuqonda Izinombolo ze-Lens Zoom
Gcina lokhu engqondweni lapho usebenza ekuqondeni ama-lenses okuqonda: Zonke izilinganiso zokusondeza kwe-optical azifani.
Isibonelo, i-lens zoom ye-10X ingaba nefilimu engu-35mm elingana no-24mm-240mm. Kodwa enye i-lens zoom ye-10X kwenye ikhamera ingaba ne-35mm-350mm elinganayo. (Lolu hlobo lwezinombolo kufanele lufakwe ohlwini lwekhamera.) Ikhamera yokuqala izohlinzeka ngamakhono angcono kakhulu angama-angle kodwa ukusebenza okungaphansi kwe-telephoto kunekhamera yesibili.
I-lens zoom lens ingasebenzisa cishe noma yikuphi ukuphakama kwe-angle ne-telephoto yokubeka ubude obude. Ukusondeza kwe-optical kubhekisela ebangeni phakathi kwalababili, kungakhathaliseki ukuthi i-angle ebanzi noma amakhono we-telephoto.
Ngenkathi i-lens zoom ye-50X yokukhanya izwakala njengesilinganiso esimangalisayo futhi ungase ucabange ukuthi inikeza amandla we-telephoto enamandla, kungenzeka ukuthi ayikwazi ukudubula esimweni se-telephoto esikhulu kunaleyo ye-lens zoom ye-42X optical zoom. Uma i-lens zoom ye-50X yokukhanya ikwazi ukubeka ama-angle angama-20mm, ukubekwa kwayo kwe-telephoto esiphezulu kuyoba ngu-1000mm (20 kwandiswa ngu-50). Futhi uma i-lens zoom ye-42X yokukhanya ikwazi ukubeka ama-angle angama-25mm, ukubekwa kwayo kwe-telephoto esiphezulu kuyoba yi-1050mm (25 ithulwe ngu-42). Qinisekisa ukuthi awuqapheli kuphela ukulinganisa kwe-optical zoom lens ethile, kodwa futhi nokubekwe kwesikhala esiphezulu se-telephoto.
Kuyafaneleka futhi ukuphawula ukuthi ezinye izilinganiso zokusondeza kwe-optical akuyona inombolo ejikelezayo. Ungathola ukusondeza okubonakalayo kwe-4.2X ngekhamera, njengokungathi ubude obusuka ku-24-100mm ku-lens zoom zoom.
