I-telephoto lens iyikhamera eyenza ukusondeza okubonakalayo. Ilensi yeperiscope iyisandiso esifanayo selensi yocingo evamile, kodwa inombombo ongunxande esikhundleni sendilinga evamile. Ilensi yeperiscope ilusizo kumalandscapes nezinye izimo uma ufuna ukubuka okubanzi kodwa ungakwazi ukusondela kakhulu. Ungayisebenzisa futhi ukuthatha izithombe ezinkulu.
Iyini ikhamera ye-Telephoto futhi isebenza kanjani?
Ikhamera ye-Telephoto ilungele ukuthwebula izinto eziseduze njengawo wonke ama-zoom lens. I-telephoto lens isusa ukuhlanekezela komgqomo ukuze idale izithombe ezicacile, ezinemininingwane. Kodwa okubi ukuthi kungaba nzima ukukusebenzisela ukuthwebula i-angle ebanzi, ngoba kudinga ukugxila okwenziwa ngesandla kumakhamera ajwayelekile. Ilensi yocingo eyedwa yanele ngezinjongo eziningi, kodwa uma ubheka ukuthatha izithombe noma ama-landscape, uzofuna i-telephoto ezacile.
I-telephoto lens ikuvumela ukuthi usondele ezihlokweni ezikude futhi uthwebule imininingwane emihle. Ukusebenzisa ilensi ye-telephoto kuhle kakhulu ezilwaneni zasendle ezikude noma izindawo ezinhle kakhulu. Isebenza kahle futhi ekudubuleni abantu, i-mountain scapes, nama-cityscapes. Ingasetshenziswa kuzo zonke izimo, kuhlanganise ngaphakathi nangaphandle. Ilungele ukuthatha izithombe zemicimbi ofuna ukuyiqopha, njengamakhonsathi noma imicimbi yezemidlalo. Kuyasiza futhi uma udinga ukusondeza esihlokweni eduze kakhulu.
Ngenkathi ikukhamera evamile njenge-Nikon noma i-Canon, ilensi ye-telephoto iyanwebeka lapho isetshenziswa, ayenzi mnyakazo kuma-smartphone. Isetshenziswa ngokuyisisekelo ukudala lowo mphumela omuhle we-bokeh kumodi yokuma ngobude.
Iyini ikhamera yePeriscope futhi isetshenziselwa ini?
Amakhamera we-periscope anamandla kakhulu adumile ngabathwebuli bezithombe. Lawa madivayisi akuvumela ukuthi usondele esihlokweni sakho ngenkathi uzuza ukudubula okungamakiwe. Futhi zilungele ukuthwebula izithombe zemvelo, ngenxa yokujula kwazo okulinganiselwe kokugxila kanye nokufiphala kwengemuva. I-Huawei's P40 Pro+, enezinzwa zekhamera ezinhlanu, izidla ngelensi ye-periscope engu-10x, elingana no-240mm ekhamera enohlaka olugcwele.
Ngenxa yesakhiwo sawo esiyingqayizivele, amakhamera we-periscope anekhono lokusondeza eliphezulu kunamakhamera avamile. Zinendawo evulekile engunxande noma emise okuka-L ngaphandle, ewela phezu kweprism ngaphakathi kwemojuli. I-prism igobisa umsebe wokukhanya ube amadigri angu-90 bese idlula kwilensi nenzwa ukuze ikhiqize isithombe esicacile. Uma umhubhe umude, ibanga lokusondeza elibonakalayo liya phezulu. Ubukhulu bebanga lokusondeza lekhamera ye-periscope ngu-5X.
Ikhamera ye-periscope iyishubhu enamalensi amabili angama-degree angu-45 nhlangothi zombili. Umsebenzisi ubheka ekugcineni futhi abone isithombe esivezwa omunye. Ilensi yeperiscope isebenzisa isibuko esisodwa ukugoba ukukhanya okungamadigri angama-90. Ngakho-ke, isithombe asisihle njenge-DSLR, kodwa sisengcono kunekhamera evamile yokukhomba bese udubula. Kodwa kufanele uqaphele ukuthi amakhamera e-periscope ngokuvamile anezithombe ezinokulungiswa okuphansi. Ungafunda izinzuzo zekhamera ye-Periscope kusuka lapha.
Umehluko phakathi kwamalensi okusondeza ikhamera ye-smartphone
I-periscope lens isetshenziselwa ukubona eduze kwezithiyo. Ineprism noma isibuko ekwakhiweni kwayo. Ubude bayo benza kube nokwenzeka ukubona ngemva kwento. I-periscope iwusizo kwezemidlalo noma eminye imisebenzi lapho kudingeka khona inkambu ebanzi yokubuka. I-periscope isetshenziswe amashumi eminyaka ezimotweni zezikhali futhi ayiyingozi ukuyisebenzisa. Ngaphandle kokusebenza, kungase futhi kube ukuhlolwa kwesayensi okujabulisayo.
Amakhamera we-Telephoto ne-periscope ahlukile ngokosayizi. Ilensi yeperiscope inendawo yokubuka encane kanye nenani lephikseli eliphansi. Inzwa yayo ivamise ukubekwa ngokuvundlile. Ngenxa yalokho, usayizi wezinzwa mncane. Lokhu kunciphisa inani lokukhanya elingena kukhamera. Ikhwalithi yesithombe se-periscope ivamise ukuba yimbi, ngakho-ke ungase ufune ukuthatha izithombe ngelensi ye-engeli ebanzi uma udinga ukuvala into ehambayo.
Ngokuphathelene nokusondeza kwe-optical, amalensi e-periscope angcono kakhulu kubathwebuli bezithombe zezwe futhi anezinzuzo eziningi. Ilensi yeperiscope ayiyona ilensi yendabuko yocingo. Umthamo wayo wokusondeza obonakalayo mkhulu kunelensi yocingo. Ikhamera izodinga isikhala esengeziwe ukuze yamukele inzwa. Ilensi yeperiscope ibiza kakhulu. Kodwa inezici nezinzuzo ezengeziwe.
Ikhamera ye-periscope inendawo yokubuka ewumngcingo futhi idinga ukukhanya okuzungezile okwengeziwe. Indawo yayo incane kunelensi ye-telephoto. I-shutter yayo idinga ukukhanya okwengeziwe ukuze ikhiqize izithombe zekhwalithi ephezulu. Ilensi yayo izohlala yehlisa ikhwalithi yesithombe njengoba isondeza. Kodwa abakhiqizi baseShayina sebeneminyaka bezama ngamakhamera we-periscope. I IHuawei P40 Pro+, isibonelo, ine-10x omnidirectional reticle ilensi yeperiscope elingana 240mm kukhamera yohlaka olugcwele.
Amalensi ePeriscope ayakwazi ukusondeza amandla aphezulu. Asetshenziswa kangcono ukudubula indawo ekude. Kodwa okubi kwamalensi e-periscope ukuthi awafaneleki kuzo zonke izimo. Amanye amalensi e-periscope angase abize kakhulu futhi awafanele ama-smartphones amaningi. Ezinye zazo zifaneleka kangcono ukuthwebula nge-telephoto, kodwa uma udinga ukuthatha izithombe zezindawo ezikude, ilensi ye-tera-periscope iyisinqumo esingcono.
Zoom Lens for Smartphones
Ukuze uthole ukubukeka kochwepheshe okwengeziwe, ungathenga namalensi okusondeza ama-smartphones. Kunezinhlobo ezimbalwa ezahlukene futhi zonke ziza namazinga ahlukene okukhulisa. Enye yezinketho ezidume kakhulu yi- I-Samsung Galaxy S9 +, enokulungiswa kwe-4K. Kodwa-ke, uma uthanda kakhulu ukuthwebula izithombe, kufanele ucabangele ikhamera ye-iPhone noma ye-Android. I-Xiaomi ingenye inketho engase ilungele izidingo zakho. I-Xiaomi brand yenze inqwaba yamafoni athengekayo anamakhamera ekhwalithi anama-zoom lens. Zihlole!
I-zoom lens edumile ye-smartphone yi I-Sony QX10. Lena imodeli enamandla kakhulu, ene-zoom yokubona engu-10X, noma okulinganayo okungu-25-250mm. Ilungele izinhlobonhlobo zezindawo zokuthwebula izithombe, futhi iyahambisana nama-smartphones amaningi esimanje. Iphinde ibe nenzwa ye-CMOS futhi ithwebule ku-18MP futhi inozinzo owakhelwe ngaphakathi. Lezi izici ezimbili ezibalulekile okufanele uzibheke lapho unquma ukuthi iyiphi ikhamera ye-smartphone ongayithenga.
I-telephoto lens yangaphandle iyindlela enhle ye-smartphone. Inganikeza ubude bokugxila obungu-12x. Le lens iyasiza futhi njenge-monocular yokuthatha izithombe. Ilensi yocingo ingaxhunywa kumakhalekhukhwini kusetshenziswa isiqeshana, okusho ukuthi akuyona nje into enhle yokuthatha izithombe ngocingo lwakho, kodwa futhi ingathuthukisa ikhwalithi yesithombe. Uma ufuna i-zoom lens ye-smartphone yakho, ungathola i-engeli ebanzi, i-macro, ne-telephoto lens ezothuthukisa ulwazi lwakho. Lawa ma-lens alingana kuma-smartphone aze afike kumamilimitha ayishumi ubukhulu. Banesikulufu esinenjoloba abazosinamathisela ocingweni. Ikhithi yelensi yendawo yonke yakwaNelomo ihlanganisa nendwangu yokuhlanza i-microfibre kanye nekesi lokuthwala eliyisivikelo. Ikhithi yelensi yefoni nayo iyahambisana nama-iPhone.
Amalensi okusondeza angaxhunywa ku-smartphone yakho ngesiqeshana. I-telephoto lens inehadiwe yekhamera ekhangayo. Inekhamera eyinhloko engu-108MP ene-OIS, i-periscope telephoto engu-10MP ene-OIS, kanye nekhamera engu-12-megapixel ultrawide ene-dual-pixel PDAF. Ngaphezu kwalokho, isekela i-Super Steady Video.
