- Isihluthulelo selensi yeselula ye-telephoto ubude obuqondile: ngaphezu kuka-50mm indawo iyacindezelwa, i-engeli yokubuka iyancishiswa futhi isithombe siyathuthukiswa.
- Amafoni aphathwayo ahlanganisa amalensi e-telephoto, ama-periscope, kanye nezinzwa ezinesinqumo esiphezulu ukuze anikeze i-optical kanye ne-hybrid zoom ngemininingwane engcono kanye nomsindo omncane.
- Izesekeli zangaphandle kanye namasethi ezithombe andisa ububanzi belensi ye-telephoto efinyelela kubude obufanayo obungu-200mm ngaphandle kwesidingo sokuphatha ikhamera enkulu.
- Ukukhetha kahle kudinga ukubheka i-optics, inzwa, ukucubungula ngisho ne-ecosystem yezesekeli, hhayi nje "ukukhulisa okungu-x" okubonakala ezicacisweni zobuchwepheshe.
Sekuyiminyaka besithengisa ukusondeza okuthuthukile Kungase kubonakale kuyindlela elula "yokusondeza izinto", kodwa iqiniso lithakazelisa kakhulu. Ilensi enhle ye-telephoto ekuthwebuleni izithombe zeselula akugcini nje ngokukuvumela ukuthi ubone ngokucacile izihloko ezikudeIphinde ishintshe ngokuphelele izilinganiso zobuso kuma-portraits, indlela ingemuva elicindezelwe ngayo, indlela isihloko esihlukaniswa ngayo, kanye nomphumela wokufiphala. Ake sichaze, ngokuthula kodwa ngokunembile, ukuthi kusebenza kanjani, ukuthi yiziphi izinhlobo ezikhona, ukuthi yini abakhiqizi ayenzile, nokuthi yimaphi amafoni nezesekeli ezikufanele uma i-zoom ibalulekile kuwe.
Ubude be-focal: inhliziyo yelensi ye-telephoto efonini ephathekayo
Ukuze uqonde ukuthi yini eyenza ilensi ye-telephoto ku-smartphone ibe ekhethekile, kufanele uqale ngezinto eziyisisekelo: ibanga eligxile (noma ubude)Kalula nje, ibanga eliphakathi kwesikhungo sokubona selensi kanye nenzwa yesithombe, evezwa ngamamilimitha (okulingana nohlaka oluphelele uma kukhulunywa ngocingo).
Kumafoni eselula anamuhla, abakhiqizi bagqamisa lesi sibalo kanye nama-megapixel: 24 mm, 50 mm, 75 mm, 120 mm… ngoba ukusebenza kwefoni kuncike kuyo. i-engeli yombono kanye nombono esizokuthola. Ngaphambilini, ngekhamera eyodwa, i-"zoom" yayimane inciphisa inzwa: amaphikseli ambalwa, imininingwane embalwa, nomsindo omningi. Manje, amakhamera amaningana anobude obuhlukene bokugxila kanye nokucubungula okunamandla ahlanganisiwe ukuze kufezwe ukusondelana okuhlanzekile kakhulu.
Ezithombeni zendabuko, ilensi ivame ukubhekwa njenge I-50mm inikeza umbono osondelene kakhulu noweso lomuntu.ngaphandle kokuhlanekezela okusobala. Phakathi kuka-35 no-50 mm sinalolo hlu "lwemvelo" lapho kungekho lutho oluhlanekezelwe ngokweqile. Ngaphansi kwalokho, singena ezweni lamalensi ane-angle ebanzi kanye ne-ultra-wide-angle; ngaphezu kwalo, umbuso wamalensi e-telephoto.
Uma sifinyelela ngaphansi kwamamilimitha angu-24, insimu yokubuka ivuleka kakhulu: uma sifinyelela ku-16 noma 13 mm singayimboza izigcawu ezivulekile kakhulu, ingaphakathi eliminyene, noma izakhiwo eziphakeme ngokuphelele...ngezindleko zokuphambukisa imiphetho. Uma sidlula ama-50mm, i-engeli yokubuka iyancipha, indawo iyacindezelwa, bese siqala "ukusondeza" lokho esikuthathayo.
Kumaselula, amalensi e-telephoto ngokuvamile abhekwa njengaqala ku-50mm okulingana. Kumakhamera endabuko, amalensi amaningi e-telephoto ngokusobala adlula u-70mm, kanti emishinini ephezulu, afinyelela ubude obuqondile ezithombeni ezintathu nezine. Nokho, ku-smartphone, ukulinganiselwa ngokomzimba kobukhulu bedivayisi Kukuphoqa ukuthi ube nobuciko obuningi.
Iyini ngempela ilensi ye-telephoto ehambayo futhi yini eyenza ihluke?
Kalula nje, ilensi ye-telephoto iyinoma iyiphi ilensi Ukusondeza izinto usebenzisa i-optics yangempela, hhayi ukunqampuna kwedijithaliUma ifoni yakho ephathekayo ikhangisa ngokuthi "2x, 3x noma 5x optical zoom", kusho ukuthi okungenani kukhona ikhamera eyodwa enobude obude bokugxila kuneyona eyinhloko, ekwazi ukufeza lokho kusondeza ngaphandle kokushintsha ukukala isithombe.
Empeleni, abakhiqizi abaningi baqala ngelensi eyinhloko engaba ngu-24-26mm bese bengeza imodyuli eyengeziwe engu-50, 70, 80, 100mm noma ngaphezulu. Lokhu kugxuma kobude be-focal yikona okunquma i-“2x, 3x, 5x…” edumile, ngakho-ke, izinga langempela lokusondeza okubonakalayo phezu kwekhamera eyinhlokoIsibonelo, ilensi ephambili engu-26mm ehlanganiswe nelensi ye-telephoto engu-52mm inikeza ukukhulisa okungu-2x; uma ilensi ye-telephoto ingu-78mm, sikhuluma ngo-3x, njalo njalo.
Ukwandisa ubude be-focal kubangela ukuthi kwenzeke izinto eziningana ngesikhathi esisodwa: i-engeli yokubuka iyancipha, ukujula kwensimu kuya ngokuya kujula, futhi ingemuva libonakala lisondele kakhulu kumuntu okhulumayo. Lokhu kucindezelwa kwemvelo kwesimo yikona okwenza kube njalo... ilensi ye-telephoto ingaba namandla anele ezithombeni, izithombe zasemadolobheni, noma ngisho nezithombe ezinkulu kwamanye omakhalekhukhwini.
Ngokuphathelene ne-engeli, yize ilensi ene-engeli ebanzi ingafinyelela ku-100-120º, ilensi ye-telephoto engu-80-100mm iyinciphisa kakhulu insimu yayo yokubuka, ijikeleza cishe ku-24-30º. Lokhu kuholela ekubumbeni okuqinile. ikhono lokuhlukanisa imininingwane nokulawula okuhle kakhulu lokho okufakiwe esithombeni.
Ngaphezu kwalokho, ukujula kwensimu okungajulile kwenza kube lula ukuhlukanisa isihloko nesizinda ngaphandle kokudinga imodi yesithombe sesofthiwe. Ukufiphala esikutholayo ngelensi ye-telephoto yeselula enhle kuyi- i-bokeh ebonakalayo ethuthukayo futhi yemvelo lowo mdwebo odwetshwe ngesandla obonakala ngezinye izikhathi ezindleleni zokubala ze-portrait.
Igxathu eliyingqophamlando: kusukela kukhamera ephindwe kabili kuya ku-periscope
Inguquko yokuqala enkulu ku-zoom yeselula yafika lapho abakhiqizi benquma ukufaka amakhamera amabili angemuva anobude obuhlukene bokugxila obungaguqukiIsibonelo esiphawulekayo kwakuyi- I-iPhone 7 Plus, ehlanganise ilensi ephambili engu-28mm nelensi ye-telephoto engu-56mm ukuze inikeze i-optical zoom engu-2x ngaphandle kokusebenzisa i-digital cropping.
Icebo lalilula: ifoni ephathekayo yayinganyakazisi ingilazi njengekhamera encane ene-zoom, kodwa kunalokho wagxuma esuka kwenye ikhamera waya kwenye Lapho umsebenzisi ecela ukusondeza okwengeziwe, konke kwakuhamba kahle kwaze kwaba yilapho i-physics ibeka umkhawulo: ukuze kufinyelelwe ukusondeza okwengeziwe, kudingeka ibanga elithe xaxa phakathi kwelensi nenzwa… futhi omakhalekhukhwini baya ngokuya bencipha.
Impendulo kwaba uhlelo lwe-periscope. Esikhundleni sokubeka amalensi emgqeni oqondile oqonde endaweni yento ehambayo, kusetshenziswa i-prism noma isibuko esisetshenziswayo. ivimbela ukukhanya okungu-90º Ivumela amalensi ukuthi abekwe ngaphakathi kwefoni. Lokhu kuthola isikhala ngaphandle kokwandisa ubukhulu be-chassis futhi kuvumela ubude be-focal obulingana no-120mm noma ngaphezulu.
Abakhiqizi abanjengoHuawei bathande le ndlela ngamalensi e-telephoto angu-3x, 5x, kanye nangokwengeziwe. Inkinga ukuthi, ukuze kufezwe ama-zoom aqine njenge-10x optical zoom emsulwa, kuzodingeka uhambo olude kangaka lwamalensi ukuthi ikhamera yayizophuma ngamasentimitha ambalwa, into engenakwenzeka maqondana nomklamo kanye nokumelana.
Ngesikhathi esifanayo, kwaqala "impi yokumaketha" mayelana nokusondeza. Amanye amabhrendi aqala ukubala ukusondeza okuphelele kusukela kulensi ye-ultra-wide-angle (isibonelo, kusukela ku-16mm kuya ku-160mm) ukuze akhangise "ukusondeza okungu-10x" noma "ukusondeza okungu-10x hybrid," yize ukwanda kwangempela kokukhanya okuvela kukhamera eyinhloko kwakungokuphindwe kahlanu kuphela. Ngamanye amazwi, Izinombolo ezikhangisweni azibonisi njalo i-optical zoom yangempela..
Intuthuko yakamuva ilethe izixazululo eziyinkimbinkimbi nakakhulu, njengezinhlelo ze-periscope ezimbili noma amalensi angaphakathi ashintsha ubude be-focal ngaphandle kwezingxenye zangaphandle ezihambayo. Sesivele sibona lokhu kwamanye amamodeli aphezulu kakhulu. Amalensi e-telephoto ashintshana phakathi kobude obubili bangempela bokugxila (isb., 3,7x kanye no-9,4x)inikeza ububanzi bokukhanya obungakaze bubonwe ngaphandle kokuthembela kakhulu ku-zoom yedijithali ephakathi.
Izinzwa ezinkulu kanye nokusondeza ngokusika: ngenye indlela
Ngesikhathi onjiniyela be-optical becindezela ama-periscopes kuze kube sezingeni labo, kwavela enye indlela yocwaningo: eyama- inzwa enesinqumo esikhuluUma ikhamera eyinhloko inama-megapixel ayi-100, 200 noma ngaphezulu, kungenzeka ukunqamula ingxenye ephakathi yesithombe ukuze ulingise ukukhuliswa okuphakathi ngaphandle kokuthi isithombe sibukeke "sine-pixel".
Umqondo ulula kakhulu: uma unenzwa engu-200MP, ungagcina ingxenye ephakathi kuphela ukuze ulingise ukusondeza okungu-2x, 4x, noma ngaphezulu, konke lokhu ngenkathi ulondoloza inani elanele lamaphikseli ukuze isithombe sokugcina sihlale sikhulu futhi sinemininingwaneLe ndlela isivele isetshenziswa kumamodeli amaningi aphezulu kusukela ngo-2025 nango-2026.
Imikhiqizo efana ne-Samsung ithuthukise leli qhinga kakhulu: inzwa yayo enkulu engu-200MP ivumela ukusondeza okuseduze kokukhanya ngokunyuka okufana no-2x no-4x ngokusika nje, ngaphandle kokushintsha amalensi. I-Sony, yona, ingene emakethe kakhulu ngezinzwa ezifana ne-200MP LYTIA, eklanyelwe ngqo omakhalekhukhwini abasezingeni eliphezulu, lapho usayizi wephikseli kanye nekhono lokuqoqa ukukhanya zibaluleke njengenani eliphelele lama-megapixel.
Kodwa-ke, le ndlela inemikhawulo ecacile. Nakuba umphumela ungaba muhle kakhulu ezimweni zokukhanya ezilawulwayo, uma ukukhanya kuncipha ngisho noma sikhulisa ukunqampuna kakhulu, Kuzwakala umsindo, ukuthungwa kubushelelezi, futhi ukucubungula kufanele kusebenze kanzima.Ngakho-ke, imiphumela emihle kakhulu itholakala ngokuhlanganisa le ndlela namalensi e-telephoto angempela.
Ekusetshenzisweni kwansuku zonke, izinhlelo ezihlanganisa inzwa enesinqumo esiphezulu namalensi e-telephoto azinikele zinikeza okuthile okuthakazelisa kakhulu: ukushintshashintsha okubushelelezi phakathi kobude obugxileEsikhundleni sokuba no-1x, 3x kanye no-5x nje, ungadlula ezinyathelweni eziphakathi (1,5x, 2x, 2,5x, 7x, 10x…) ngenkathi ugcina ikhwalithi efanayo.
Izesekeli zangaphandle: lapho ifoni ephathekayo “iphula” ishasi
Kufika isikhathi lapho, kungakhathaliseki ukuthi ulungisa kangakanani, ungakwazi ukuthola okunye ukuhamba okubonakalayo ngocingo ngaphandle kokuphazamisa umklamo. Futhi yilapho sebeqale khona ukuthola ukuthandwa. amalensi e-telephoto angaphandle kanye nama-modular photography kits for Smartphones.
Amanye amabhrendi akhethe amakesi afana ne-bayonet ukuze afake amalensi engeziwe, izibambo ezinamabhethri ahlanganisiwe, kanye nezinhlelo zamagnetic ezivumela ifoni ephathekayo ukuthi iguqulwe ibe uhlobo lwe- ikhamera engenasibuko ephaketheniUmqondo ucacile: uma ungakwazi ukufaka i-200mm ngaphakathi kwe-chassis, uyayikhipha bese uyifaka uma uyidinga.
Isibonelo esiyinhloko amakhithi afaka ilensi yangaphandle "ye-super telephoto" engaba ngu-200mm ukuze ihambisane nelensi yendabuko yefoni. Lezi zesekeli zisebenza njengengilazi yokukhulisa esezingeni eliphezulu kumojuli ye-telephoto, ziphindaphinda ububanzi bayo bokukhanya ukuze ikwenze... ikhambi elisebenzayo lezithombe zasesiteji, zemvelo noma ezemidlalo ngaphandle kokuphatha ikhamera enkulu.
Nokho, akuphelele konke. Uma ufaka ilensi yangaphandle yalolu hlobo, kuvame ukwenzeka ukuthi amanye amakhamera efonini (eyinhloko kanye ne-engeli ebanzi) azokhutshazwangoba isesekeli sivimbela insimu yabo yokubona. Ngaphezu kwalokho, i-ergonomics ishintshiwe ngokuphelele: yonke into inkulu, iyabonakala kakhulu, futhi yandisa ingozi yamaqhubu nemivimbo.
Kuvamile futhi ukuthi isofthiwe idinga ukuzivumelanisa nezimo: ngokuvamile, izindlela ezithile (njenge-"telephoto extender") zidinga ukwenziwa zisebenze ukuze ifoni isebenzise ukulungiswa kwelensi okufanele, ukugxila, kanye nokuzinza. Ngaphandle kwalolu sizo, isithombe singabonakala siguquliwe, sifiphele, noma sineziphambeko ezivelele kakhulu.
Naphezu kwalezi zingqinamba, izesekeli zangaphandle zinengqondo kakhulu kubasebenzisi abakwaziyo lokho Bazobhekana nezimo ezithile kakhuluAmakhonsathi, imicimbi ekude, izilwane zasendle, izithombe zokuhamba ezidinga umzamo omkhulu… Kulezi zimo, ukuphatha ifoni ephathekayo enelensi ye-telephoto enhle kanye nekhithi yangaphandle kungathatha indawo yekhamera ye-zoom yendabuko.
Yini enikezwa ilensi ye-telephoto ekuthwebuleni izithombe zeselula ngale "kokusondeza"?
Iphutha elivame kakhulu uma kukhulunywa ngamalensi e-telephoto kumaselula ukucabanga ukuthi awusizo kuphela ekuboneni izinto ezikude eduze, njengokungathi ifoni iyisibonakude nje. Iqiniso liwukuthi Inani layo lokudala kanye nelobuchwepheshe lidlula kakhulu lokho.
Kuma-portraits, isibonelo, umehluko uyamangalisa. Amalensi ane-engeli ebanzi ajwayelekile kumakhamera amakhulu ahlanekezela ubuso uma usondeza isithombe: impumulo emikhulu, izindlebe ezincane, amabunzi agqamileKuwukuhlanekezelwa kombono okwaziwayo. Ngokuhamba kude nomuntu okhulumayo bese usebenzisa ilensi ye-telephoto, ugcina izilinganiso zemvelo kakhulu nezithandekayo.
Ngaphezu kwalokho, ilensi ye-telephoto icindezela indawo, okwenza ingemuva libonakale liseduze nomuntu othintekayo. Lokhu kucindezela Kuyinika ukubukeka kwe-cinema kakhudlwanaikakhulukazi ezithombeni nasezigcawini zasemadolobheni lapho ufuna khona izakhiwo, izibani noma izakhi zemvelo zibonakale kahle ngemuva komuntu.
Ukujula kwensimu okungajulile nakho kusiza ukuhlukanisa ngokubonakalayo into ekhona ngemuva. Ngisho noma kunezinzwa ezincane, ilensi ye-telephoto eklanywe kahle ingakhiqiza i-bokeh yangempela ebushelelezi, eqhubekayo, futhi ekhilimu, ihluke kakhulu kumaski yokufiphaza imodi yesithombe se-AI.
Ezithombeni zasemadolobheni kanye nezindawo ezizungezile, ilensi ye-telephoto ilungele kakhulu hlukanisa imininingwane ethileIfasitela elikhanyayo esakhiweni, umuntu onqamula indlela, isiqongo sentaba phansi kwesigodi. Lapho ilensi ebanzi ivame ukuhlanganisa yonke into ibe yindawo ebanzi, ilensi ye-telephoto ikuvumela ukuthi uxoxe izindaba ezincane ngaphakathi kwengqikithi enkulu.
Kwamanye amafoni aphathwayo akamuva, i-TV nayo isibe isikhali esiyimfihlo se-macroNgenxa yekhono lokugxila eduze kakhulu nangobude obude kakhulu bokugxila, ukuthungwa, izinambuzane noma izinto ezincane kungathathwa ngaphandle kokubeka ikhamera ngqo kumuntu okhulumayo, kunciphisa izithunzi, ukuzindla kanye nezinkinga zokugxila.
Ilensi ye-Telephoto, i-AI kanye nezithombe zekhompyutha: iqembu elibusayo
Ilensi ye-telephoto ayisebenzi yodwa. Imiphumela esiyibonayo kumafoni e-zoom angcono kakhulu namuhla iwumkhiqizo wenhlanganisela eyinkimbinkimbi ye ama-optics, izinzwa ezinkulu, kanye nama-algorithms e-AI lokho kulungisa isithombe ngasinye ngokushesha.
Uma kwenzeka amamodeli akamuva aphezulu, ilensi ye-telephoto incike ezinzwa ezingama-50, 48, noma ngisho nama-200 MP, ukuzinza kwesithombe okuthuthukisiwe (i-OIS), kanye nokucubungula okwaziyo ukuthi kufanele kuhlanganiswe nini ulwazi oluvela kumakhamera amaningi ukuze kuthuthukiswe imininingwane futhi kuncishiswe umsindo. Umgomo uwukufeza ushintsho olubushelelezi kusuka ku-1x kuya ku-3x, 5x, noma i-10x zoom. Akufanele kube noshintsho olubonakalayo olusheshayo kumbala, ukugqama, noma ukuthungwa..
Imikhiqizo efana ne-Samsung ikhethe izinhlelo ezimbili ze-telephoto (isibonelo, i-3x kanye ne-5x) ezihlanganiswe nokusikwa kwenzwa eyinhloko engu-200MP ukuze inikeze ukusondeza "ikhwalithi yokukhanya" ngezinyathelo eziphakathi ezifana ne-2x kanye ne-10x. Abanye, njenge-Apple, bathuthukise kusuka kuma-sensor angu-12MP baya ku-48MP kumamodeli abo e-Pro ukuze bakwazi ukunikeza. amaphuzu agxile kakhulu "abonakalayo" anekhwalithi enhle (13 mm, 24 mm, 28 mm, 35 mm, 48 mm, 120 mm, 240 mm…) ngaphandle kokwengeza amamojula angapheli angokwenyama, futhi ayasebenza futhi amaqhinga okuthola okuningi ku-iPhone yakho.
Ngasohlangothini lokuhlola lwe-Android, abakhiqizi baseShayina bathathe isinyathelo esithe xaxa amalensi e-telephoto amade e-periscope, izinzwa ze-zoom ezinikezelwe ku-200MP, kanye nezesekeli zangaphandleAmamodeli avela ku-vivo, i-OPPO, i-HONOR noma i-realme agxile kumalensi e-telephoto ukuze kuthathwe izithombe zasemgwaqweni, izithombe noma i-zoom exakile, aze adlale ngamabanga alinganayo angu-85, 100 noma ngisho no-200 mm ngemiphumela eminyakeni embalwa edlule eyayibonakala njengenganekwane yesayensi kuselula.
I-Google, ngakolunye uhlangothi, iguqule i-telephoto yaba enye inkundla yokudlala ngezithombe zayo zekhompyutha: ngezinzwa ze-48 MP kanye ne-5x optical zoom, esekelwa yi-digital zoom efinyelela ku-100x, amafoni e-Pixel aphezulu abonisa ukuthi kanjani I-AI ingacindezela yonke i-photon yokugcina ukugcina ubukhali nemininingwane lapho ezinye izingcingo zincibilika khona zibe ama-watercolor edijithali.
Noma kunjalo, wonke lomlingo uza ngentengo: amafayela amakhulu, ukusetshenziswa kwebhethri okuphezulu kanye nokucutshungulwa okudinga kakhulu yeprosesa nememori. Uma usebenzisa kakhulu ubude obude be-focal kanye nezindlela ezinesisombululo esiphezulu, uzobona ngokushesha umthelela empilweni yebhethri kanye nesitoreji.
Izibonelo zamafoni aphathwayo aqukethe kakhulu amalensi e-telephoto
Imakethe ka-2026 igcwele iziphakamiso ezahlukene, kodwa kunezindlela ezimbalwa ezicacile emkhakheni wethelevishini:
Ngakolunye uhlangothi sinamaqhawe akudala afana SamsungAmamodeli e-Ultra afaka ilensi ye-telephoto ekabili (imojula eyodwa ene-zoom engaba ngu-3x yama-portraits kanye nenye efinyeleleka kakhulu ekuthwebuleni izithombe ezikude), esekelwa yinzwa eyinhloko engu-200 MP. Lokhu kuvumela ukuhlanganisa i-optical zoom kanye ne-cropping nezinyathelo eziphakathi zekhwalithi, kanye nokufeza i-digital zoom efinyelela ku-100x, okuthi, nakuba ingaphelele, isetshenziswe ngokumangalisayo.
Ku-ecosystem ye AppleAmamodeli e-Pro Max afake ilensi ye-periscope telephoto ene-5x optical zoom, esekelwa yizinzwa ze-48MP kanye nokucubungula kwazo okudumile kwe-photonic. Lokhu kubavumela ukuthi banikeze ulwazi oluqinile kakhulu ku- izithombe zesithombe kanye nezithombe ezikudengemibala ehambisanayo kanye nokushintshashintsha okubushelelezi phakathi kwamalensi.
Bese sithola abakhiqizi baseShayina abake bafuna ngokusobala ukuzihlukanisa ne-TV: i-OPPO, i-vivo, i-HONOR, i-Xiaomi noma i-realme baqalise amamodeli amakhulu nge Amalensi e-telephoto angu-200MPNjengoba ubude obuqondile bulingana no-65, 85, noma 100 mm, izinzwa ezinkulu, kanye nokuzinza okunamandla, lawa mafoni aklanyelwe labo abathanda izithombe ze-zoom kanye ne-portrait ngaphezu kwakho konke okunye.
Amanye amamodeli afaka nama-photographic kit ongakhetha kuwo: ama-grip athuthukisa ukuphathwa futhi ahlanganise ibhethri elengeziwe, amasongo esibambi sokuhlunga ukuze asetshenziswe ama-polarizers noma izihlungi ze-ND, njengasekhamera yobungcweti...futhi ngisho namalensi angaphandle anweba i-telephoto yomdabu afinyelela ku-200mm okulingana. Konke lokhu kunengqondo yokuthi ungamboza uhambo, umcimbi, noma umbiko wasedolobheni usebenzisa ifoni yakho ephathekayo kanye nekhithi encane esikhwameni sakho.
Amafoni agoqekayo akhombisile nokuthi i-form factor akudingeki ilahle amandla okusondeza. Sekuvele kukhona amadivayisi anemizimba engaphansi kuka-5 mm ubukhulu ahlanganisa... amalensi e-telephoto angokoqobo ajikelezayo (3x) Ngenxa yezinzwa ezihlanganisiwe kanye nemiklamo emincane yokukhanya, okufakazela ukuthi ilensi ye-telephoto akuyona indawo ekhethekile "yezitini" ezisindayo kakhulu.
I-Telephoto uma iqhathaniswa ne-wide-angle: ukushintsha izinto eziza kuqala
Isikhathi eside, kwakuthathwa kalula ukuthi ikhamera ebanzi kakhulu yayibalulekile kunoma iyiphi ifoni ephathekayo efuna ukuzigqaja ngokuguquguquka: izithombe zeqembu, ingaphakathi, izakhiwo… Kodwa, ngokuvuthwa kwezithombe zeselula, Ilensi ye-telephoto iye yathuthuka..
Akuyona into engaqondakali ukuthi uma umkhiqizo ufuna ukunciphisa izindleko noma ukunciphisa imininingwane, Ikhamera yokuqala elahliwe ngokuvamile ilensi ebanzi kakhulu. noma incishiswa ibe yisigaba sesibili ngezinzwa ezincane kanye nama-optics abuthakathaka. Ngakolunye uhlangothi, ilensi ye-telephoto isibe uphawu lwebanga eliphakathi kuya kweliphezulu kanye neliphezulu, ngoba yilapho umsebenzisi ebona khona igxathu langempela lokudala.
Ilensi ene-angle ebanzi kakhulu isasebenza, vele, kodwa izinkinga zayo zaziwa kahle: Ukusebenza okungekuhle kokukhanya okuphansi, ukuphazamiseka kwekhoneni, ukuphambuka kwejometri Futhi, ezimweni eziningi, ikhwalithi iphansi kakhulu kuneyekhamera eyinhloko. Ngakolunye uhlangothi, ilensi enhle ye-telephoto ivula umnyango wezithombe zobungcweti, ukwakheka okunembile kwasemadolobheni, kanye nokusondeza "kwangempela".
Lo mkhuba uyabonakala nasendleleni abantu abasebenzisa ngayo amakhamera. Abathwebuli bezithombe abaningi beselula kanye nabasebenzisi abathuthukile bayavuma ukuthi Ilensi abayikhumbula kakhulu uma ingekho ilensi ye-telephoto.Akuyona ilensi ebanzi kakhulu. Ukubhala ku-2x, 3x, noma 5x kunikeza umuzwa wokulawula ukufometha nokuxoxa indaba okunzima ukukopisha ngekhamera eyodwa eyinhloko.
Ngisho nemikhiqizo eyaqala igxile kakhulu ekwakhiweni noma esibonakalayo, njenge-Nothing, igcine ibheja ezicini kumamodeli ayo akamuva. Amalensi e-telephoto akhula ngamandla kanye nemisebenzi emikhulu exhunywe kula malensiNgoba yilapho abasebenzisi abafuna izinto eziningi becela khona ukuthuthukiswa.
Okufanele ukucabangele lapho ukhetha ifoni ephathekayo ngokusekelwe kulensi yayo ye-telephoto
Uma i-zoom iyisici esibalulekile kuwe, ungagxili nje kuphela esithombeni esithi "x magnification" esikhangisweni. Kunamaphuzu amaningana abalulekile okufanele uwabukeze ngokucophelela futhi ngokuhlolwa kwangempela noma nini lapho kungenzeka.
Into yokuqala ngukuthi ikhwalithi yangempela yokukhanya yelensi ye-telephotoUkulungiswa, ubukhali phakathi nasemakhoneni, izinga lemininingwane ezigcawini zasemini nasebusuku, kanye nendlela ephatha ngayo isikhumba ezithombeni. Ukuba nama-megapixel amaningi akwanele; ukukhanya okuphakathi noma ukucubungula okunamandla kungonakalisa ilensi ebukeka ithembisa ephepheni.
Okwesibili, bheka usayizi kanye nokusebenza kwenzwa eyinhlokoUma umkhiqizo uthembele kakhulu ekunqumeni kwedijithali ukuze unikeze izinyathelo zokusondeza eziphakathi, udinga inzwa enkulu, enokuthwebula ukukhanya okuhle kanye nokucubungula okunekhono ukuze ukusondeza "okungeyikho" okungu-2x noma okungu-4x kusondele kakhulu ngelensi yangempela ye-telephoto.
Enye inkinga okufanele icatshangelwe yile ukuhambisana nezesekeli zangaphandle: amakesi e-bayonet, amalensi e-telephoto anamathiselwayo, ama-grip, izibambo zokuhlunga… Uma uzibona usebenzisa ifoni yakho ephathekayo njengethuluzi lokuthwebula izithombe elibalulekile, ungase ube nesithakazelo ohlelweni lwezesekeli oluklanywe kahle.
Ungakhohlwa umthelela wokugcina kanye nokuphila kwebhethri. Izithombe ezinesinqumo esigcwele kanye nokusetshenziswa okujulile kwe-zoom ende, ividiyo ye-4K/8K, kanye nezindlela ze-RAW noma ze-SuperRAW kuzolimaza kakhulu. Zigcwalisa inkumbulo futhi zidle ama-milliamp ngokusheshaHlola umthamo wesitoreji sangaphakathi sefoni, amathuba (noma cha) okunwebeka ngekhadi le-microSD, kanye nosayizi webhethri kanye nesivinini sokushaja.
Ekugcineni, hlola ukuthi ifoni iphatha kanjani ukuhambisana kombala kanye nomehluko phakathi kwamalensiUhlelo oluhle lwekhamera lusho ukuthi ukushintsha kusuka kukhamera eyinhloko uye kulensi ye-telephoto (noma i-ultra-wide-angle) kubonakala kuphela ohlakeni, hhayi esikhumbeni, ekushiseni kombala, noma ekuhlukeni okuphelele.
Namuhla, ukuqonda ukuthi amalensi e-telephoto asebenza kanjani ezithombeni zeselula, ukulinganiselwa kwawo ngokomzimba, izingibe zokumaketha, kanye nezixazululo zobuchwepheshe zomkhiqizo ngamunye kukuvumela ukuthi ukhethe kangcono kakhulu, futhi ngaphezu kwakho konke, sebenzisa ikhamera osunayo kakade ephaketheni lakhoKusukela esithombeni sokuqala kuya ohambweni lokugcina, ngefoni nje kuphela, futhi uma uzimisele, kune-TV encane efakwe kuyo.
