Yiziphi Izilinganiso Ezivamile Zokugxila Kwamalensi Ezimboni? Yiziphi Izinto Okufanele Zicatshangelwe Lapho Ukhetha Imodeli?

1,Yiziphi ubude obuvame ukusetshenziswa bamalensi ezimboni?

Kunezindlela eziningi zokugxila ezisetshenziswa kuamalensi ezimboniNgokuvamile, kukhethwa ububanzi obuhlukene bobude obuqondile ngokwezidingo zokudubula. Nazi ezinye izibonelo ezivamile zobude obuqondile:

A.Ubude obuqondile obungu-4mm

Amalensi alolu bude obuqondile afaneleka kakhulu ekudubuleni izindawo ezinkulu kanye nebanga eliseduze, njengezindawo zokusebenzela zasefektri, izindawo zokugcina impahla, njll.

B.Ubude obuqondile obungu-6mm

Uma kuqhathaniswa nelensi yobude obuqondile engu-4mm, lena ilensi yobude obuqondile ende kancane, efaneleka ngezikhathi ezinkulu kancane. Imishini eminingi emikhulu yezimboni, njengamathuluzi omshini asindayo, imigqa yokukhiqiza emikhulu, njll., ingasebenzisa ilensi engu-6mm.

C.Ubude obuqondile obungu-8mm

Ilensi engu-8mm ingathwebula izigcawu ezinkulu, njengomugqa omkhulu wokukhiqiza, indawo yokugcina impahla, njll. Kufanele kuqashelwe ukuthi ilensi yalolu bude obuqondile ingabangela ukuphambuka kwesithombe ezigcawini ezinkulu.

D.Ubude obuqondile obungu-12mm

Uma kuqhathaniswa nelensi yobude obuqondile obungu-8mm, ilensi engu-12mm inobubanzi bokudubula obubanzi futhi ifaneleka kakhulu ukusetshenziswa ezigcawini ezinkulu.

E.Ubude obuqondile obungu-16mm

Ilensi yobude obuqondile obungu-16mm ilensi yobude obuphakathi nendawo, efanelekela ukudubula ebangeni eliphakathi nendawo. Ingasetshenziswa ukudubula izingxenye ezithile zefektri, njengemishini, imishini, njll.

F.Ubude obuqondile obungu-25mm

Ilensi engu-25mm ilensi efana ne-telephoto, efaneleka kakhulu ekudubuleni ibanga elide, njengokudubula umbono obanzi wefektri yonke usuka endaweni ephakeme.

G.Ubude obungama-35mm, 50mm, 75mm kanye nobunye ubude obuqondile

Amalensi afana no-35mm, 50mm, no-75mm angamalensi amade anobude obuqondile angasetshenziswa ukuthwebula izithombe zezimboni ezikude, noma ukuthwebula izithombe ezinkulu (ibanga lokudubula eliseduze kakhulu) ukuze kuthwetshulwe imininingwane eyengeziwe esithombeni.

2,Yiziphi izici okufanele zicatshangelwe lapho ukhetha amalensi ezimboni?

Uma ukhethailensi yezimboni, izici ezilandelayo zidinga ukucatshangelwa:

A.Izidingo zesicelo

Ngaphambi kokukhetha ilensi, nquma ukuthi yiluphi uhlobo lwelensi oludingwa uhlelo lwakho lokusebenza. Ngoba izinhlelo zokusebenza ezahlukene zidinga izinhlobo ezahlukene zamapharamitha njengokuvula, ubude be-focal kanye nensimu yokubuka.

Isibonelo, ingabe udinga ilensi ene-wide-engela noma ilensi ye-telephoto? Udinga ikhono lokugxila noma lokusondeza eliqinile? Lokhu kunqunywa ngokusekelwe ezidingweni zohlelo lokusebenza.

B.Amapharamitha okukhanya

Imbobo, ubude obuqondile kanye nensimu yokubuka konke kuyimingcele ebalulekile yelensi. Imbobo inquma inani lokukhanya okudluliselwa yilensi, futhi imbobo enkulu ingafinyelela ikhwalithi yesithombe engcono ezimweni zokukhanya okuphansi; ubude obuqondile kanye nensimu yokubuka kunquma insimu yokubuka kanye nokukhulisa isithombe.

C.Isithomberisixazululo

Uma ukhetha ilensi, udinga futhi ukukhetha ilensi efanelekile ngokusekelwe ezidingweni zokulungiswa kwesithombe. Ukulungiswa kwelensi kufanele kufane namaphikseli ekhamera ukuqinisekisa izithombe ezisezingeni eliphezulu.

D.Ikhwalithi yokubona yelensi

Ikhwalithi yokubona yelensi inquma ngqo ukucaca nokuhlanekezela kwesithombe. Ngakho-ke, lapho ukhetha ilensi, kufanele ucabangele ilensi evela kumkhiqizo othembekile ukuqinisekisa ukusebenza okuzinzile kokubona.

E.Ukuzivumelanisa nezimo kwemvelo

Uma ukhetha ilensi, udinga futhi ukucabangela izimo zemvelo zesicelo sakho. Isibonelo, uma indawo yesicelo inezici ezifana nothuli, umswakama, noma izinga lokushisa eliphezulu, udinga ukukhetha ilensi engangeni uthuli, engangeni manzi, futhi engangeni izinga lokushisa eliphezulu.

F.Isabelomali selensi

Isabelomali singenye yezinto ezibalulekile okufanele uzicabangele lapho ukhetha ilensi. Izinhlobo ezahlukene zamalensi zinamanani ahlukene, ngakho qiniseka ukuthi ukhetha ilensi efanele ngokwesabelomali sakho.

Imicabango Yokugcina:

UChuangAn wenze umklamo wokuqala kanye nokukhiqizwa kweamalensi ezimboni, ezisetshenziswa kuzo zonke izici zezicelo zezimboni. Uma unesithakazelo noma unesidingo samalensi ezimboni, sicela usithinte ngokushesha okukhulu.
