Iilensi zeVarifocalzivumela uhlengahlengiso oluguquguqukayo lobude befocal, okuvumela ukuba kuthathwe iintlobo ezahlukeneyo zeefoto ngelensi enye. Zizixhobo eziyimfuneko kwicandelo lokufota, ezisetyenziswa kakhulu, kwaye zithandwa kakhulu ngabafoti.
Usetyenziso oluthile lweelensi ze-varifocal kwimifanekiso luquka, kodwa alukhawulelwanga, koku kulandelayo:
1.Imifanekiso yelizwe
Ukufota ngendlela ye-landscape kugxile kakhulu kwimiboniso ebanzi kunye neenkcukacha ezintsonkothileyo, kwaye ubude obuhlengahlengiswayo be-lens ye-varifocal bubonelela ngeenzuzo ezinkulu ezisebenzayo kule nkalo. Ukusebenzisa ilensi ye-varifocal ukwenza uyilo kukuvumela ukuba ubambe umxholo wesiganeko kwindawo efanayo, njengengxangxasi ekude okanye umlambo ehlathini, ugqamise umxholo ophambili.
Kwangaxeshanye, isiphelo se-telephoto sinokucinezela isithuba, sizise iintaba ezikude kunye nomphambili kufutshane kwaye siphucule ingqiqo yobunzulu kumfanekiso. Ukusebenzisa isiphelo se-engile ebanzi ekubumbeni kudla ngokusetyenziswa ukufota iintaba ezinkulu, amachibi, kunye nolwandle lwamafu, ezinokubandakanya izinto ezingqongileyo ezingaphezulu kwaye ziphucule ingqiqo yendawo kunye nobukhulu kumfanekiso.
Xa uthatha imifanekiso kwiindawo ezintsonkothileyo, ezinje ngeentaba kunye neentlambo, ukusebenzisa ilensi ye-varifocal kunokuthatha imifanekiso ye-wide angle kunye neenkcukacha ezikufutshane, kunciphisa umthwalo wokuthwala imithwalo enzima kunye neendleko zexesha lokutshintsha iilensi.

2.Imifanekiso yemifanekiso
Ukufota ngemifanekiso kufuna inqanaba eliphezulu lokufota kunye nokufiphala kwemvelaphi.iilensi ze-varifocalNgokwe-focal length ingahlangabezana neemfuno ezahlukeneyo zokuyila, inceda ekucinezeleni umbono, iqaqambise umxholo, kwaye ivumelane nemifanekiso yokusingqongileyo kunye nemizobo ekufutshane.
Umzekelo, ukusebenzisa ubude obuqhelekileyo befocal (obufana ne-35-50mm) ukufota imifanekiso yokusingqongileyo kunokuqwalasela zombini umxholo kunye nommandla ongasemva, okubangela imifanekiso yendalo neyobusondeleyo; ukusebenzisa ubude befocal betelephoto (obufana ne-85-200mm) ukufota imifanekiso yobunzulu obunganzulu bentsimi kusebenzisa isiphumo sokucinezelwa kwelensi yetelephoto ukwenza imvelaphi ibe lula kwaye isiphumo sebokeh sithambe, esifanelekileyo ngakumbi ekufoteni imifanekiso ekufutshane okanye imifanekiso yomzimba ophakathi kwiindawo ezixineneyo.
3.Iifoto zokuhamba
Uphawu "lwelensi enye-yonke" lweelensi ze-varifocal lukwafanelekile kakhulu ekufoteni uhambo. Ukusebenzisa ilensi ye-varifocal kukuvumela ukuba uziqhelanise notshintsho lweendawo ezahlukeneyo (imbonakalo yomhlaba, abantu, imifanekiso, njl.njl.), ukunciphisa inani leelensi ekufuneka uziphathe, kunye nokunciphisa ubunzima bemithwalo yakho. Ifanelekile ngokukodwa ekuhambeni intaba, ukuzulazula ezidolophini, kunye nezinye iimeko.
Umzekelo, ukuphatha ilensi ye-varifocal enobude obuyi-24-105mm okanye i-18-200mm kunokugubungela lonke ubude obuyi-focal ukusuka kwiindawo ezibanzi ukuya kwiifoto eziphakathi, ukuhlangabezana neemfuno ezahlukeneyo zokudubula iindawo, ii-portraits, kunye nokutya ngelixa useluhambeni.

4.Isitalato/di-ocumentarypi-hotography
Ukufota esitalatweni kunye nokufota iidokhumentari, njengeefoto ezicacileyo esitalatweni kunye nokurekhodwa kwemisebenzi yabantu, kufuna ukufota amaxesha okwenyani ngobuchule kunye nokugqibezela umfanekiso ngaphandle kokuphazamisa umntu othatha inxaxheba. Oku kufuna ilensi ekwaziyo ukuphendula ngokukhawuleza nangokuguquguqukayo, kwayeiilensi ze-varifocalbanokuqhelana notshintsho olunzima kangaka lwendalo.
Umzekelo, ukusebenzisa isiphelo se-wide angle kukuvumela ukuba uthwebule imifanekiso emikhulu esitalatweni, urekhode unxibelelwano phakathi kwabantu kunye nokusingqongileyo, kwaye uphucule indlela ebaliswa ngayo imifanekiso; ukusebenzisa isiphelo se-telephoto esiphakathi ukuya kweside kukuvumela ukuba uthwebule amaxesha endalo ngakumbi xa ukude nomxholo.
5.Ezemidlalo/wubomi bezilwanyanapi-hotography
Iilensi zeVarifocal zisetyenziswa rhoqo kwiimeko ezifuna ukufotwa kweefoto ezikude—ezifana nezemidlalo kunye neefoto zezilwanyana zasendle—ezivumela abafoti ukuba bathathe imifanekiso ngokukhawuleza ngaphandle kokuphazamisa umntu ochaphazelekayo.
Umzekelo, ilensi ye-varifocal engama-70-200mm inokubamba umzuzu wokubaleka kwiziganeko zomdyarho kunye nezemidlalo, iqande imifanekiso eguquguqukayo; ilensi ye-varifocal engama-100-400mm idibanisa ukugubungela nge-telephoto kunye nokuphatheka, okwenza ifaneleke ukulandelwa kwexesha elide kunye nokufotwa kwezilwanyana zasendle endle.

6.Ifoto yesibhakabhaka esineenkwenkwezi
Iilensi ze-Varifocal wide angle zibonelela ngokulinganisela phakathi kokugubungela i-wide-engile kunye nokuguquguquka kokwakheka, kwaye kwiminyaka yakutshanje, zikwasetyenziswa nakwiifoto zeenkwenkwezi esibhakabhakeni. Ukusebenzisa ilensi ye-16-35mm wide angle kukuvumela ukuba ubambe umbono we-panoramic we-Milky Way, ngelixa usebenzisa ithuba lokusondeza ukulungisa ukwakheka—ukuthatha okungakumbi kwe-Milky Way okanye ukugqamisa indawo engundoqo.
Ukusetyenziswa kwelensi ye-varifocal kususa ingxaki yokutshintsha ikhamera ngokwasemzimbeni, nto leyo eyenza ukuba ifaneleke kakhulu ukudubula kwiindawo ezingaphandle ezinemida, njengeentaba, iintlango, kunye nee-canyons.
Ukwengeza,iilensi ze-varifocalikwanazo nezicelo zobungcali kwiimeko ezikhethekileyo ezifana nokufota ii-macro, ukudubula iifilimu kunye neevidiyo, kunye nokuhlolwa kwemizi-mveliso.
Ngamafutshane, iilensi ze-varifocal zisetyenziswa kakhulu kwicandelo lokufota—ngenxa yokukwazi kwazo ukulungisa ubude be-focal ngokuguquguquka—kwaye zibonise ukusebenza okugqwesileyo kwiimeko ezifuna ukuziqhelanisa ngokukhawuleza neziganeko ezitshintshayo okanye ukwenza lula ukuphatheka kwezixhobo. Abafoti banokulungisa ubude be-focal kunye nendawo yekhamera ngokufanelekileyo ngokwemeko ethile yesicelo.
Iingcinga Zokugqibela:
Ukuba unomdla wokuthenga iintlobo ngeentlobo zeelensi zokujonga, ukuskena, iidrone, ikhaya elikrelekrele, okanye naluphi na olunye uhlobo lokusetyenziswa, sinazo izinto ozifunayo. Nxibelelana nathi namhlanje ukuze ufunde okungakumbi ngeelensi zethu kunye nezinye izixhobo.
