Iimpawu kunye neemeko ezisebenzayo zeLensi yeVarifocal kunye neLensi yoQokelelo oluZinzileyo

Xa kufikwa kuiilensi ze-varifocal, sinokwazi ngegama layo ukuba le yilensi enokutshintsha ubude befocal, eliyilensi etshintsha ukwakheka kokudubula ngokutshintsha ubude befocal ngaphandle kokuhambisa isixhobo.

Ngokwahlukileyo koko, ilensi yokugxila esisigxina yilensi engenakutshintsha ubude befocal, kwaye ukuba ufuna ukutshintsha indlela yokudubula, kufuneka ushukumise indawo yekhamera ngesandla.

1,Iimpawu zei-varifocalilensi kunyeukugxila okuzinzileyoilensi

Singazibona iimpawu ze-varifocal lens kunye ne-fixed focus lens kweli gama, size sijonge ezithile:

(1)Iimpawu zei-varifocalilensi

A. Ubude befocal bungatshintshwa, ilensi enye inika ubude obahlukeneyo befocal, inokuziqhelanisa neemfuno ezahlukeneyo zokudubula;

B. Ulwakhiwo lulonke luyinkimbinkimbi, kuquka amaqela eelensi ezininzi, ilensi idla ngokuba nkulu, inkulu kakhulu;

Ubungakanani be-Aperture buhlala buncinci, nto leyo enciphisa amandla okudubula kwiindawo ezinokukhanya okuphantsi;

D.Ngenxa yoyilo oluntsonkothileyo lwelensi, inokuchaphazela ukucaca kunye nobukhali bomfanekiso;

Ukutshintsha ubude be-focal kususa ngqo isidingo sokutshintsha iilensi kwaye kunciphisa uthuli kunye nokungcola okufakwa kukutshintsha iilensi.

(2)Iimpawu zeukugxila okuzinzileyoilensi

A. Kuphela ubude obujoliswe ngqo obungaguqukiyo, lungisa ubude obujoliswe ngqo obunokushukunyiswa ngesandla kuphela;

B. Ulwakhiwo lulula kakhulu, luneelensi ezimbalwa, ubunzima obulula, kunye nomthamo omncinci;

C. Ingaba nesithuba esikhulu sokuvula nokudubula kwiindawo ezinokukhanya okuphantsi;

D.Ngenxa yesakhiwo sayo esilula, imifanekiso idla ngokuba cacileyo kwaye ibukhali ngakumbi.

2,Iimeko ezisebenzayo kwii-varifocaliilensi kunyeukugxila okuzinzileyoiilensi

Iimpawu zeiilensi ze-varifocalkunye neelensi zokugxila ezizinzileyo zichonga iimeko zazo ezahlukeneyo ezifanelekileyo:

(1)Iimeko ezisebenzayo kwii-varifocaliilensi

A. Ukuhamba: Ilensi enye ye-varifocal yanele uninzi lweemfuno.

B.Ukufota imitshato: Ifanelekile kwiindawo zokudubula ezikhawulezayo ezifuna ukugubungela ubude obahlukeneyo befocal.

C. Isetyenziselwa ukunika ingxelo ngemifanekisoUmzekelo, kwiimeko ezifana nokufota iindaba ezifuna impendulo ekhawulezileyo kwiimeko ezahlukeneyo,iilensi ze-varifocalingakhawuleza i-varifocal ukuhlangabezana neemfuno zokudubula.

Ukufota imitshato

(2)Iimeko ezisebenzayo kwiukugxila okuzinzileyoiilensi

A.Ukufota imveliso: Ilensi yokugxila esisigxina inokuba nokusebenza kakuhle kokukhanya kunye nolawulo lomgangatho womfanekiso xa uthatha imifanekiso ephilayo.

B.Ukufota esitalatweniUkusebenzisa ilensi yokugxila engaguqukiyo kunyanzela umfoti ukuba ashukume ngakumbi aze akwazi ukukhangela iindawo ezifanelekileyo kunye nee-engile.

C. Ngeefoto zobuchule: Ezifana nokufota imifanekiso ye-portrait, ukufota i-landscape, njl.njl., zinokwenza ubunzulu obuhle bempembelelo yentsimi ngokusebenzisa umngxuma omkhulu.

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.
