Ziyintoni na iiNombolo kwiiLensi zokuLawulwa kweKhamera?
Umbuzo: Zithini ukuba iinombolo zetekisi zetekisi zithetha ntoni? Iyintoni inkcazo ye-zoom yekhamera?
A: Ukuqonda ii-lens zekhamera, ngokukodwa iilensi ze-zoom zekhamera zedijithali, ingaba yinkqubo enobuqili. O qi nikile: Amanani abhalwe ngeekhamera zoom zoom zibonakala zilula ngokwaneleyo. Isilinganiselo se-zoom ye-zoom ye-10X yincinci encinci, ngelixa i-50X yokulinganisa imilinganiselo yokulinganisa ilingana ne-lens zoom enkulu. Kwaye unokudubula kumgama omde kakhulu kunye ne-lens enkulu yokwenza i-lens kune-lens encane.
Ngelixa ezi ngcaciso zilula ngokwaneleyo ukufotowa okuyisiseko, abaxeli ibali lonke. Ukufuna iimpapasho ezicacileyo ngakumbi, ukuqonda okungcono ikhamera yokusondeza ikhamera kubalulekile. Qhubeka ufunda ukuze ufunde okungakumbi malunga neekhamera zokusondeza iilensi.
Zoom Lens Inkcazo
Izalathisi ze-lens zekhamera yedijithali zibonisa ukuba inani lokukhulisa i-lens liyakwazi ukuvelisa. Amanani anokudidanisa, nangona kunjalo, kuba abanye abavelisi baphakamisa imilinganiselo eyahlukeneyo, kubandakanywa ukusondeza okubonakalayo, ukusondeza kwedijithali , kunye nokusondeza okuhlangeneyo. Gcina oku engqondweni xa usebenza ekuqondeni iilensi zethamo:
Utsalane lokubonakalayo luyona mlinganiselo wesondlo esibaluleke kakhulu kuba ulinganisa ububanzi bendawo yobude beli lensi, ngokusekelwe kwakhiwo sokwenyama kwilensi. Njengoko ikhamera ishukumisa izinto zeglasi kwi-lens, ubude becala kwenguqu yentsholongwane, ukunika ububanzi obude obunqwenela kwi-lens zoom.
I-zoom zoom yedijithali yindlela yokulinganisa ububanzi bendawo yobude ukuba isofthiwe yekhamera idala. Esikhundleni sokuhambisa izinto ezisemzimbeni zentsholongwane ukuba zitshintshe ubude obunzulu be-lens, isofthiwe yekhamera iphakamisa umfanekiso njengoko iboniswe kwisikrini se-LCD, ukudala ukukhohlisa kwesikrini se-zoom. Ngenxa yokuba isilinganiselo sokwenza idijithali nje sikhulisa umfanekiso, sinokuphumela ekulahlekeni kobukhali kwisithombe, ngoko ke ukusebenzisa i-zoom yedijithali ayicebisi ngaphandle kokuba ungenayo enye into. Ikhamera ye-smartphone ingasebenzisa ulwelo lwedijithali kuphela.
Abanye abenzi bekhamera basebenzisa eli gama ukudibanisa ukudibanisa ukuchaza iilensi zabo, nangona eli lide elide. Utsalane oludibeneyo lubhekisela kwisilinganiselo se-lens yokulinganisa kokubili ukutsala kwe-optical kunye ne-zoom yedijithali eyongeziweyo kunye.
Ukuqonda i-Numom Lens Numbers
Gcina oku engqondweni xa usebenza ekuqondeni iilensi zethamo: Zonke izilinganiso ze-zoom ze-zoom azifani.
Ngokomzekelo, i-lens zoom ye-10X ingaba nefilimu engama-35mm engama-24mm-240mm. Kodwa enye i-zoom ye-10X yelinye ikhamera ingaba ne-35mm-350mm elinganayo. (Olu luhlu lwamanani lufanele ludweliswe kwiinkcazo zeekhamera.) Ikhamera yokuqala iya kunika amandla angcono kumandla amaninzi kodwa ingaphantsi kwee-telephoto ukusebenza kunekhamera yesibili.
I-lens zoom lens ingasebenzisa phantse nayiphi na i-angle ephakamileyo kunye ne-telephoto yokubeka ubude bendawo. I-zoom zoom ibonisa ububanzi phakathi kwezi zibini, kungakhathaliseki ukuba liphi na i-angle ebanzi okanye i-telephoto.
Nangona i-lens ye-zoom ye-50X ijonga njengomlinganiselo oncomekayo kwaye ungacinga ukuba inika amandla i-telephoto, inokuthi ayikwazi ukudubula kwisitopu se-telephoto ekulu njengokuba i-lens ye-zoom ye-42X. Ukuba i-lens ye-zoom ye-50X ine-angle engama-20mm, i-telephoto yokubeka ilungiselelo liza kuba yi-1000mm (iphindwe ngu-50). Yaye ukuba i-lens zoom ye-42X i-angle engama-25mm, i-telephoto yokubeka i-telephoto isithuba esingu-1050mm (i-25 yanda ngo-42). Qinisekisa ukuba awuqwalasela kuphela ukulinganisa kwe-optical zoom ye-lens ethile, kodwa nakwi-optimal setting yayo.
Kukwafanelekile ukuba uqaphele ukuba amanye amanyathelo okutsalwa kwe-optical ayikho inombolo ejikelezayo. Unokufumana ukubonakala kwe-4.2X ngekhamera, njengokuba ubude obude be-24-100mm kwi-lens zoom zoom.
