Amalensi e-Varifocalikuvumela ukuthi ulungise ubude bokugxila ngaphandle kokushintsha indawo yakho yokudubula, okunikeza ukuguquguquka okukhulu kanye nokuzivumelanisa nezimo nezidingo ezahlukene zokudubula, futhi zisetshenziswa kabanzi ekuthwebuleni izithombe zomhlaba.
Uma uthwebula izithombe zezindawo, ukukhetha ilensi ye-varifocal efanele kudinga ukucabangela izici ezifana nobude be-focal, izinhloso zokudubula, kanye nezici zesigcawu. Kulesi sihloko, sizohlola lezi zici ndawonye.
1.Indawo enkulu
Uma uthwebula izithombe zezindawo ezinkulu, njengezintaba, izindawo ezinotshani, amahlane, kanye nogu lolwandle, lapho ubukhulu bendawo yonke budinga ukuthwetshulwa khona, kudingeka insimu ebanzi yokubuka, umuzwa wokwandiswa, noma ukujula kwendawo. Kulezi zimo, ilensi ye-varifocal ene-angle ebanzi kakhulu iyafaneleka, enobude obuqondile obufana no-10-24mm noma 16-35mm.
Isibonelo, lapho kuthwetshulwa umbono obanzi wentaba embozwe yiqhwa, ilensi ye-varifocal esebenzisa ilensi ye-ultra-wide-angle ingabamba amatshe ngaphambili ngasikhathi sinye, izitshalo eziphakathi nendawo, kanye nentaba embozwe yiqhwa ngemuva, okugqamisa umuzwa wokujula esikhaleni.

2.Indawo enobukhulu obuphakathi nendawo
Uma uthwebula izithombe zezindawo ezisezingeni eliphakathi, njengamachibi, amasimu, noma imigqa yedolobha, kubalulekile ukugqamisa imininingwane ethile noma ubudlelwano phakathi kwesihloko nendawo esikuyo.amalensi e-varifocal, ezinobude obuqondile obufana no-24-70mm noma 24-105mm, zifaneleka kule njongo, njengoba ngokwemvelo zenza isilinganiso kanye nobudlelwano bendawo bendawo.
Ububanzi obugxile kumalensi ajwayelekile e-varifocal buhlanganisa imibono evame ukusetshenziswa, okuvumela ukwakheka okuguquguqukayo nokulinganisela kokubili indawo yonke kanye nezinto ezinemininingwane. Isibonelo, ubude obugxile obungaba ngu-50mm bungasetshenziswa ukubamba ukukhanya nesithunzi ehlathini, kuyilapho umphumela wokucindezela wobude obugxile obungu-70mm ungasetshenziswa ukugcizelela isikebhe esincane echibini.
3.Indawo ekude
Ukuthwebula izithombe zezindawo ezikude, njengezintaba nezilwane zasendle, noma ezinye izigcawu ezingafinyeleleki, kudinga ilensi ekwazi ukuthwebula izinto ezikude, ukucindezela isikhala, noma ukugqamisa imininingwane. Kulezi zimo, ilensi ye-telephoto varifocal enobude obuqondile obufana no-70-200mm noma u-100-400mm iyafaneleka. Umphumela wokucindezela ngelensi ye-telephoto ungabeka izinto ezikude, noma uhlukanise into ngemuva, kuyilapho ukudubula kude kusiza nokugwema ukuphazamisa imvelo noma ukuqinisekisa ukuphepha komuntu siqu.
Isibonelo, lapho kuthwetshulwa izithombe zezintaba ezikude, ukuthungwa kwamafu, noma iqhwa eziqongweni zezintaba, ilensi ye-telephoto ingasondeza isihloko, igqamise imininingwane kanye nokuthungwa; lapho kuthwetshulwa izithombe zezintaba ezinezingqimba, amasimu anezingqimba, noma amahlathi, umphumela wokucindezela kwendawo ngelensi ye-telephoto ungadala umuzwa wokujula kanye nokugcwala esithombeni.

4.Izindawo ezihlanganisa izinto zabantu
Uma uthwebula izithombe zezindawo ezihlanganisa izinto zabantu, njengezigcawu ezinabantu nezakhiwo (isb., abelusi kanye nezindawo zotshani, amathempeli namahlathi asendulo), kunconywa ukusebenzisa indinganisoilensi ye-varifocalLokhu kuzosiza ekugwemeni ukuhlanekezelwa okungavamile kwabantu noma izakhiwo ngenxa yombono.
5.Ukubuka okubanzi endaweni evalekile
Uma uthwebula ama-panorama ezindaweni ezivalekile njengezigodi noma imizila yamahlathi, ukusebenzisa ilensi ene-angle ebanzi kakhulu kungcono, njengoba ikuvumela ukuthi uthwebule umbono ophelele wendawo usendaweni elinganiselwe.
6.Ukuqoshwa kohambo lwansuku zonke kanye nokuthwebula izithombe
Ukuze kuthathwe izikhathi zokuhamba zansuku zonke, ilensi idinga ukuthwalwa kalula, iguquguquke ekubunjweni kwayo, futhi ikwazi ukushintsha ngokushesha izigcawu (njengokusuka ezimbalini ezingaphambili notshani kuya ezintabeni eziphakathi nendawo), ngokumbozwa okubanzi kobude bokugxila ukuze kungadingeki izinguquko ezivamile. Ilensi ejwayelekile ye-varifocal ifaneleka kule njongo.

7.Ukudubula ezimweni zokukhanya okuphansi
Uma uthwebula ezimweni zokukhanya okuphansi, njengasekuphumeni kwelanga, ekushoneni kwelanga, noma ezinsukwini ezinamafu, kungcono ukhethe ilensi ye-varifocal enembobo enkulu, njengelensi engu-16-35mm noma engu-24-70mm enembobo ye-f/2.8 engaguquki. Lokhu kuqinisekisa isivinini se-shutter esisheshayo futhi kunciphisa ukufiphala kwesithombe. Ngokuphambene nalokho, ezimweni zokukhanya okukhanyayo, njengasemini, ungasebenzisa ilensi ye-varifocal enembobo encane (njenge-f/4 noma i-f/5.6) ukuze ugcine izinto eziseduze nezikude zigxile.
Ngamafuphi, lapho uthwebula izithombe zezindawo, kufanele ucabangele izici ezifana nebanga lesihloko, izici zezindawo, kanye nezimo zokukhanya ukuze ukhethe indawo efanele.ilensi ye-varifocal, ngaleyo ndlela kukhulisa amandla okuveza izithombe zakho zezwe.
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.
