Ingabe Amalensi Ezimboni Angasetshenziswa Njengamalensi e-SLR? Yimaphi Amapharamitha Okufanele Siwanake Lapho Sikhetha Amalensi Ezimboni?

1,Ingabe amalensi ezimboni angasetshenziswa njengamalensi e-SLR?

Imiklamo kanye nokusetshenziswa kweamalensi ezimboninamalensi e-SLR ahlukile. Nakuba womabili engamalensi, indlela asebenza ngayo nezimo asetshenziswa kuzo zizohluka. Uma usendaweni yokukhiqiza yezimboni, kunconywa ukusebenzisa ama-lens akhethekile wezimboni; uma wenza umsebenzi wokuthwebula izithombe, kunconywa ukuthi usebenzise amalensi ekhamera ochwepheshe.

Amalensi ezimboni adizayinelwe ngokugxila ekunembeni, ukuqina, kanye nokuzinza, ikakhulukazi ukuze ahlangabezane nezidingo zokukhiqiza nezinye izinhlelo zokusebenza zobungcweti, njengokusetshenziswa okukhethekile kokuzenzakalela, ukubhekwa, ucwaningo lwezokwelapha, nokuningi.

Idizayini yamalensi e-SLR ngokuyinhloko idinga ukucabangela ukusebenza kokubona, ukuvezwa kobuciko nolwazi lomsebenzisi, njll., ukuze kuhlangatshezwane nezidingo zabathwebuli bezithombe zekhwalithi yesithombe nokusebenza okusha.

Nakuba ngokobuchwepheshe kungenzeka ukufaka ilensi yezimboni ekhamera ye-SLR (inqobo nje uma kufanelana nesixhumi esibonakalayo), imiphumela yokudubula ingase ingabi mihle. Amalensi ezimboni angase anganikezi ikhwalithi yesithombe engcono kakhulu noma ukusebenza, futhi angase angasebenzi nokuvezwa kwekhamera yakho okuzenzakalelayo noma isistimu yokugxila ngokuzenzakalela.

Ikhamera ye-SLR

Ngezidingo ezithile ezikhethekile zokuthatha izithombe, njengokuthwebula izithombe ezincanyana eziseduze, kungafakwaamalensi ezimbonikumakhamera we-SLR, kodwa lokhu ngokuvamile kudinga amathuluzi asekelayo ochwepheshe nolwazi lochwepheshe ukuze kusekelwe ukuqedwa.

2,Yimiphi imingcele okufanele siyinake lapho sikhetha amalensi ezimboni?

Lapho ukhetha i-lens yezimboni, udinga ukucabangela imingcele ehlukahlukene. Amapharamitha alandelayo avamise ukugxila kuwo:

Ubude bokugxila:

Ubude bokugxila bunquma inkambu yokubuka nokukhulisa ilensi. Ubude bokugxila bude buhlinzeka ngokubukwa nokukhulisa ububanzi bebanga elide, kuyilapho ubude bokugxila obufushane bunikeza inkambu yokubuka ebanzi. Ngokuvamile kuyanconywa ukukhetha ubude bokugxila obufanele ngokusekelwe ezidingweni zezimo ezithile zohlelo lokusebenza.

Imbobo:

Imbobo inquma inani lokukhanya okudluliselwa ngelensi futhi ithinta ukucaca nokujula kwesithombe. Imbobo ebanzi ivumela ukuchayeka okungcono nekhwalithi yesithombe ezimeni zokukhanya okuphansi. Uma ukukhanya kwesigcawu osidubulayo kungenamandla, kunconywa ukuthi ukhethe ilensi enembobo enkulu.

Isixazululo:

Ukulungiswa kwelensi kunquma imininingwane yesithombe engayithwebula, ngokulungiswa okuphezulu okuhlinzeka ngezithombe ezicacile, ezinemininingwane eyengeziwe. Uma unezidingo eziphakeme zokucaca kwezithombe ezithathiwe, kuyanconywa ukuthi ukhethe ilensi enokulungiswa okuphezulu.

Ilensi yezimboni

Inkambu yokubuka:

Inkambu yokubuka isho ububanzi bezinto i-lens engamboza, ngokuvamile evezwa ngama-engeli avundlile naqondile. Ukukhetha inkambu efanele yokubuka kuqinisekisa ukuthi ilensi ingakwazi ukuthwebula uhla lwesithombe olufunekayo.

Uhlobo lwesixhumi esibonakalayo:

Uhlobo lwesixhumi esibonakalayo selensi kufanele lufane nekhamera noma okokusebenza okusetshenzisiwe. Okuvamileilensi yezimboniizinhlobo zesixhumi esibonakalayo zifaka i-C-mount, i-CS-mount, i-F-mount, njll.

Ukuhlanekezela:

Ukuhlanekezela kubhekisela ekuwohlokeni okwethulwa ilensi lapho ithwebula into kusici se-photosensitive. Ngokuvamile, amalensi ezimboni anezidingo eziphakeme ekuhlanekeni. Ukukhetha ilensi enokuhlanekezela okuphansi kungaqinisekisa ukunemba nokunemba kwesithombe.

Ikhwalithi yelensi:

Ikhwalithi yelensi ithinta ngokuqondile ukucaca nokukhiqizwa kombala kwesithombe. Lapho ukhetha i-lens, udinga ukuqinisekisa ukuthi ukhetha uhlobo oluphezulu lwelensi kanye nemodeli.

Ezinye izimfuneko ezikhethekile: Lapho ukhetha amalensi ezimbonini, kudingeka futhi ucabangele ukuthi indawo esetshenziswa kuyo inezidingo ezikhethekile zelensi, njengokuthi ingabe ayingeni manzi, ingangenwa uthuli, futhi imelana nezinga lokushisa eliphezulu.

Imicabango yokugcina:

UChuangAn wenze umklamo wokuqala kanye nokukhiqizwa kwamalensi ezimboni, asetshenziswa kuzo zonke izici zezicelo zezimboni. Uma unentshisekelo noma unezidingo zeamalensi ezimboni, sicela usithinte ngokushesha ngangokunokwenzeka.
