Isithombe esikhulu se-telephotoamalensi, ikakhulukazi lezo ezinobude obuqondile obungu-300mm nangaphezulu, zingamathuluzi abalulekile ekuthwebuleni izithombe zezinyoni, okukuvumela ukuthi uthwebule izithombe ezicacile nezinemininingwane ngaphandle kokuphazamisa ukuziphatha kwazo, okufana nomphumela wokusebenzisa isibonakude esikhulu.
Kulesi sihloko, sizofunda ngokusetshenziswa kwamalensi e-super telephoto ekuthwebuleni izithombe zezinyoni.
1.Ikhono lokubamba ibanga elide
Ngenxa yokuthi izinyoni zivame ukuhlala ezindaweni ezikude nabantu, amalensi e-super-telephoto anikeza ukukhulisa okuphezulu kakhulu, okwenza abathwebuli bezithombe bakwazi ukuthwebula izithombe ezinemininingwane yezinyoni ezikude ngaphandle kokuphazamisa ukuziphatha kwazo kwemvelo. Lesi sici sibaluleke kakhulu lapho kuthwetshulwa izithombe zezinyoni ezithile ezingavamile.
Isibonelo, ezindaweni zokugcina imvelo noma endle, ukusebenzisa ilensi ye-ultra-telephoto kukuvumela ukuthi ungawanaki izithiyo ezifana nezihlahla nendawo bese uthwebula ngqo izidleke zezinyoni esihlahleni sezihlahla noma imihlambi yezinyoni ezifudukayo emanzini. Usebenzisa ilensi engu-600mm, ungadubula izinto eziqhele ngamasentimitha angu-90 ubude ebangeni elingamamitha ayi-100, okwenza kube lula ukuthwebula umzuzu wama-hummingbird eshaya amaphiko awo noma izinkozi zizingela.

2.Ukulawulwa kokucindezelwa kwesikhala nokwakheka
Isithombe esikhulu se-telephotoamalensiinikeza umphumela wokucindezela okubonakalayo onamandla, osondeza izinyoni ezikude eduze nesizinda, okwenza zibonakale ngokucacile ohlakeni. Lokhu kufiphaza isizinda, kugqamise isihloko, kudala umuzwa oqinile wokujula kokubona.
Lesi sici samalensi e-super telephoto sivumela abathwebuli bezithombe ukuthi bagxile emininingwaneni ethile yezinyoni, njengokuthungwa kwezimpaphe noma ukunyakaza komlomo, noma ukudala izingqikithi zokudala.
Isibonelo, lapho uthwebula isithombe se-crane enomqhele obomvu emi endaweni emanzi, ukuphuma kwelanga namafu ngemuva kungahlanganiswa nesihloko ngelensi, kuthuthukise ukulandisa kwesithombe.
3.Ukugxila okusheshayo nokudubula okusheshayo
Izinyoni zivame ukuhamba ngokushesha kakhulu, ngakho-ke ukuthwebula izithombe zezinyoni kudinga impendulo esheshayo, ukugxila okusheshayo kanye nokudubula okusheshayo kuyizidingo ezibalulekile. Amalensi e-Super telephoto ngokuvamile afakwe uhlelo lokugxila olusheshayo, olungaqeda ukugxila ngesikhathi esifushane futhi lubambe izikhathi eziguquguqukayo zezinyoni.
Isibonelo, uma isinamathiselo se-super-telephoto sisetshenziswa nelensi ye-F4.5 aperture, sinikeza ukusebenza okuhle kakhulu ngisho nasezimweni ezikhanyayo; lapho kuthwetshulwa izithombe ze-swifts ezihlaselayo, ingagxila ngemizuzwana engu-0.5 kuphela, ibambe ngokushesha amandla esikhashana.

4.Isixazululo esiphezulu kanye nokunikezwa okuningiliziwe
Isithombe esikhulu kakhuluilensiabakwazi nje kuphela ukudubula izinyoni zikude, kodwa futhi bathwebula izithombe zezinyoni eziseduze ngokulungisa ubude be-focal. Leli khono livumela abathwebuli bezithombe ukuthi bathwebule imininingwane efana nokuthungwa kwezimpaphe zenyoni kanye nokubukeka kobuso, okuthuthukisa ukuvezwa kwezithombe zabo.
Isibonelo, lapho kuthwetshulwa isithombe sepigogo lisakaza izimpaphe zalo ngelensi ye-super-telephoto, ukuthungwa kwezimpaphe zalo okunama-scaly kungabuyiselwa ngokusobala. Uma kuhlanganiswe ne-teleconverter (njenge-1.4x noma i-2x), ilensi engu-600mm ingafinyelela ubude obufanayo obuyi-840mm (1.4x) noma i-1200mm (2x), kufezwe umphumela "we-telescopic microscopic", ofanele ukuthwebula isakhiwo se-microscopic sezinto zokwakha izidleke zezinyoni (njengeziqu zotshani nezimpaphe).
5.Ukuzivumelanisa nezimo eziyinkimbinkimbi
Ilensi ye-super telephoto iguquguquka kakhulu ezindaweni ezahlukene futhi ifanele ukusetshenziswa ezimweni zokukhanya ezahlukene njengokukhanya kwelanga okunamandla noma izinsuku ezinamafu.
Isibonelo, ezindaweni ezinokukhanya okuphansi, amalensi e-super telephoto avame ukudinga izilungiselelo ze-ISO ephezulu noma i-flash ukuze athwebule izilwane zasendle nezemidlalo. Lapho kuthwetshulwa izithombe zezinyoni emaxhaphozini noma emahlathini, abathwebuli bezithombe bangakhetha ukusebenzisa ilensi ye-super telephoto ene-tripod noma ukuzinza kwesithombe emzimbeni ukuqinisekisa izithombe ezizinzile.

6.Izicelo ezikhethekile kanye namasu ahlukahlukene
Isithombe esikhulu se-telephotoamalensiingasetshenziswa futhi ukudala imibono eyingqayizivele kanye nokuzwakalisa, hhayi nje kuphela ekuthwebuleni izithombe zomzimba wonke zezinyoni kodwa futhi nasekuthwebuleni izithombe eziseduze.
Isibonelo, ngokushintsha i-engeli yokudubula kanye nobude bokugxila, noma ngokusebenzisa ubuchwepheshe bokulawula kude, abathwebuli bezithombe bangathwebula ukuziphatha kwezinyoni noma ukusondelana kwazo ezindaweni ezifihliwe, bathwebule indlela eguquguqukayo yezinyoni ezindizayo noma ubuhle obungaguquki bezinyoni eziphumule. Lapho kuthwetshulwa izithombe zezingulule ezindaweni zotshani zase-Afrika, ilensi engu-600mm ivumela ukubanjwa kwezingulule ngaphakathi kwemoto efihliwe. Ilensi engu-100-400mm ivumela ukubanjwa kwamehlo ezinyoni, izimpaphe, kanye neminye imininingwane.
Imicabango Yokugcina:
Uma unesifiso sokuthenga izinhlobo ezahlukene zamalensi okuqapha, ukuskena, ama-drones, ikhaya elihlakaniphile, noma olunye uhlobo lokusetshenziswa, sinalokho okudingayo. Xhumana nathi namuhla ukuze ufunde kabanzi ngamalensi ethu nezinye izesekeli.
Isikhathi sokuthunyelwe: Okthoba-24-2025
