Iilensi zeVarifocalikuvumela ukuba ulungise ubude befocal ngaphandle kokutshintsha indawo yakho yokudubula, nto leyo enika ukuguquguquka okukhulu kunye nokuzivumelanisa neemfuno ezahlukeneyo zokudubula, kwaye zisetyenziswa kakhulu kwimifanekiso yelizwe.
Xa ufota i-landscapes, ukukhetha ilensi ye-varifocal efanelekileyo kufuna ukuqwalasela izinto ezifana nobude be-focal, iinjongo zokudubula, kunye neempawu zesimo. Kweli nqaku, siza kuhlola ezi zinto kunye.
1.Imbonakalo yomhlaba enkulu
Xa ufota iindawo ezinkulu, ezifana neentaba, ingca, iintlango, kunye nonxweme, apho ubukhulu bendalo bufanele ukubanjwa khona, kufuneka indawo ebanzi yokujonga, uvakalelo lolwandiso, okanye ubunzulu bendawo. Kwezi meko, ilensi ye-varifocal ebanzi kakhulu ifanelekile, enobude obuphambili obufana ne-10-24mm okanye i-16-35mm.
Umzekelo, xa uthatha umfanekiso wentaba egqunywe likhephu, ilensi ye-varifocal esebenzisa ilensi ye-ultra-wide-angle ingathatha ngaxeshanye amatye angaphambili, izityalo ezisemhlabeni, kunye nentaba egqunywe likhephu ngasemva, nto leyo ebonisa ubunzulu bendawo.

2.Imbonakalo yomhlaba ephakathi
Xa ufota imimandla ephakathi, efana namachibi, amasimi, okanye imigca yesixeko, kuyimfuneko ukugqamisa iinkcukacha ezithile okanye ubudlelwane phakathi kwento ekuthethwa ngayo nendawo ekuyo.iilensi ze-varifocal, ezinobude obuphambili obufana ne-24-70mm okanye i-24-105mm, zifanelekile kule njongo, njengoko ngokwemvelo zibonisa umlinganiselo kunye nobudlelwane bendawo yendawo.
Uluhlu oluphambili lweelensi ze-varifocal ezisemgangathweni lugubungela iimbono ezisetyenziswa rhoqo, okuvumela ukwakheka okuguquguqukayo kunye nokulinganisela zombini indawo iyonke kunye nezinto ezineenkcukacha. Umzekelo, ubude obuphambili obumalunga ne-50mm bungasetyenziselwa ukubamba ukukhanya kunye nomthunzi ehlathini, ngelixa isiphumo sokucinezelwa kobude obuphambili obuyi-70mm singasetyenziselwa ukugxininisa isikhephe esincinci echibini.
3.Imbonakalo ekude
Ukufota iindawo ezikude, ezifana neentaba nezilwanyana zasendle, okanye ezinye iindawo ezingafikelelekiyo, kufuna ilensi ekwaziyo ukufota izinto ezikude, ukucinezela indawo, okanye ukuqaqambisa iinkcukacha. Kwezi meko, ilensi ye-telephoto varifocal enobude obuphambili obufana ne-70-200mm okanye i-100-400mm ifanelekile. Isiphumo sokucinezelwa kwelensi ye-telephoto sinokubeka izinto ezikude, okanye sahlukanise umntu ngasemva, ngelixa ukudubula kude kukwanceda ukuphepha ukuphazamisa okusingqongileyo okanye ukuqinisekisa ukhuseleko lomntu.
Umzekelo, xa kufotwa imilo yeentaba ezikude, ubume bamafu, okanye ikhephu kwiincopho zeentaba, ilensi ye-telephoto inokusondeza loo mntu, iqaqambise iinkcukacha kunye nobume; xa kufotwa iintaba ezineengqimba, amasimi aneengqimba, okanye amahlathi, isiphumo sokucinezelwa kwendawo selensi ye-telephoto singenza uvakalelo lobunzulu kunye nobukhulu kumfanekiso.

4.Imihlaba equka izinto zabantu
Xa ufota iindawo eziquka izinto zabantu, njengemiboniso yabantu nezakhiwo (umz., abelusi kunye namadlelo engca, iitempile zamandulo kunye namahlathi), kuyacetyiswa ukusebenzisa umgangathoilensi ye-varifocalOku kuya kunceda ukunqanda ukugqwethwa okungaqhelekanga kwabantu okanye izakhiwo ngenxa yembono.
5.Umbono we-panoramic kwindawo evalekileyo
Xa uthatha imifanekiso kwiindawo ezixineneyo ezifana neentlambo okanye iindlela zamahlathi, ukusebenzisa ilensi ebanzi kakhulu yeyona nto ifanelekileyo, kuba ikuvumela ukuba ubambe umbono opheleleyo wendalo kwindawo enomda.
6.Ukurekhoda uhambo lwemihla ngemihla kunye nokudubula
Ukuze kuthathwe imifanekiso yemihla ngemihla, ilensi kufuneka ithwalwe lula, iguquguquke kwindlela ebhalwe ngayo, kwaye ikwazi ukutshintsha ngokukhawuleza imifanekiso (efana neentyatyambo ezingaphambili nengca ukuya kwiintaba eziphakathi komhlaba), igqunywe ngobude obubanzi ukuze kungabikho mfuneko yokutshintsha rhoqo. Ilensi eqhelekileyo ye-varifocal ifanelekile kule njongo.

7.Ukudubula kwiimeko zokukhanya okuphantsi
Xa ufota kwiimeko eziphantsi kokukhanya, njengaxa kuphuma ilanga, xa litshona ilanga, okanye xa lifumile, kungcono ukhethe ilensi enkulu ene-varifocal, efana nelensi ye-16-35mm okanye ye-24-70mm ene-f/2.8 aperture engaguqukiyo. Oku kuqinisekisa isantya sokuvala esikhawulezayo kwaye kunciphisa ukufiphala komfanekiso. Ngokwahlukileyo koko, kwiimeko zokukhanya okuqaqambileyo, njengasemini, ungasebenzisa ilensi ye-varifocal ene-aperture encinci (efana ne-f/4 okanye i-f/5.6) ukugcina izinto ezikufutshane nezikude zigxile.
Ngamafutshane, xa ufota imbonakalo yomhlaba, kufuneka uqwalasele izinto ezinje ngomgama oya kumntu owuthathayo, iimpawu zembonakalo yomhlaba, kunye neemeko zokukhanya ukuze ukhethe indawo efanelekileyo.ilensi ye-varifocal, ngaloo ndlela ukwandisa amandla okubonakalisa imifanekiso yakho yembonakalo yomhlaba.
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.
