Yintoni Eyona Njongo YeeLensi Zemizi-mveliso? Ziziphi Iintlobo ZeeLensi Zemizi-mveliso Ezisetyenziswa Kakhulu?

1,Yintoni injongo ephambili yeelensi zemizi-mveliso?

Iilensi zemizi-mvelisoziilensi ezenzelwe ukusetyenziswa kwemizi-mveliso, ezisetyenziselwa kakhulu ukujonga ngamehlo, ukuqaphela imifanekiso kunye nokusetyenziswa kombono womatshini kwicandelo lemizi-mveliso.

Iilensi zemizi-mveliso zineempawu zokuba nesisombululo esiphezulu, ukugqwetheka okuphantsi, umahluko ophezulu kunye nokusebenza kakuhle kombala. Zinokubonelela ngemifanekiso ecacileyo nechanekileyo ukuhlangabezana neemfuno zokufunyanwa ngokuchanekileyo kunye nolawulo lomgangatho kwimveliso yemizi-mveliso.

Iilensi zemizi-mveliso zihlala zisetyenziswa kunye nemithombo yokukhanya, iikhamera, isoftware yokucubungula imifanekiso kunye nezinye izixhobo zokufumanisa iziphene zomphezulu wemveliso, ukulinganisa ubukhulu, ukubona amabala okanye izinto zangaphandle, kunye nezinye iinkqubo zenkqubo ukuphucula ukusebenza kakuhle kwemveliso kunye nomgangatho wemveliso. Iilensi zemizi-mveliso zidlala indima ebalulekileyo kwinkqubo yemveliso yamashishini ahlukeneyo afana neemoto, izixhobo ze-elektroniki, amayeza, kunye nokutya.

2,Ziziphi iintlobo zeelensi zemizi-mveliso ezisetyenziswa rhoqo ezikhoyo?

Ilensi yemizi-mvelisolicandelo elibalulekileyo kwinkqubo yokubona koomatshini. Umsebenzi ophambili welensi yezimboni kukubona ngeliso elibonakalayo, okudlala indima ebaluleke kakhulu kumgangatho wokubona ngeliso. Kukho iintlobo ezininzi zeelensi zezimboni ezisetyenziswa rhoqo ngokweendlela ezahlukeneyo zokuhlela.

①Ngokweendlela ezahlukeneyo zokunxibelelana kweelensi zemizi-mveliso, zingahlulwa zibe:

A.Ilensi yemizi-mveliso efakelwe kwi-C:Yilensi yemizi-mveliso esetyenziswa kakhulu kwiinkqubo zokubona koomatshini, kunye neenzuzo zobunzima obulula, ubungakanani obuncinci, ixabiso eliphantsi kunye nohlobo olubanzi.

B.Ilensi yemizi-mveliso efakelwe kwi-CS:Uqhagamshelo olunemisonto lwe-CS-mount lufana nolwe-C-mount, oluyi-interface esemgangathweni eyamkelweyo kwihlabathi liphela. Iikhamera zoshishino ezine-CS-mount zinokuqhagamshela kwi-C-mount kunye neelensi ze-CS-mount, kodwa ukuba kusetyenziswa ilensi ye-C-mount kuphela, kufuneka iringi ye-adaptha ye-5mm; iikhamera zoshishino ze-C-mount azinakusebenzisa iilensi ze-CS-mount.

C.F-faka imboni ilensi:I-F-mount yindlela eqhelekileyo yokusebenzisana kweempawu ezininzi zeelensi. Ngokwesiqhelo, xa umphezulu wekhamera yemizi-mveliso ungaphezulu kwe-intshi enye, kufuneka ilensi ye-F-mount.

②Ngokwee-focal lengths ezahlukeneyoiilensi zoshishino, zinokwahlulwa zibe:

A.Ilensi yemizi-mveliso egxile ngokungaguqukiyo:ubude obungaguqukiyo befocal, umngxuma ohlengahlengiswayo ngokubanzi, umsebenzi wokulungisa ukugxila, umgama omncinci wokusebenza, kunye notshintsho lwe-engile yebala lokujonga ngomgama.

B.Zoomilensi yemizi-mveliso:Ubude befocal bunokutshintshwa rhoqo, ubungakanani bukhulu kunelensi yefocal esisigxina, ifanelekile kutshintsho lwezinto, kwaye umgangatho wepikseli awulunganga njengelensi yefocal esisigxina.

③Ngokwendlela ukwandiswa kwezinto okuguquguqukayo ngayo, kunokwahlulwahlulwa kube:

A.Ilensi yemizi-mveliso yokukhulisa engaguqukiyo:ukukhulisa okuzinzileyo, umgama ozinzileyo wokusebenza, akukho sithuba, akukho mfuneko yokulungisa ingqwalasela, izinga eliphantsi lokuguquguquka, ingasetyenziswa kunye nomthombo wokukhanya we-coaxial.

B.Ilensi yemizi-mveliso yokukhulisa eguquguqukayo:Ukwandiswa kunokulungiswa ngokungenamanqwanqwa ngaphandle kokutshintsha umgama wokusebenza. Xa ukwandiswa kutshintsha, kusabonisa umgangatho womfanekiso ogqwesileyo kwaye kunesakhiwo esintsonkothileyo.

Iingcinga Zokugqibela:

UChuangAn wenze uyilo lokuqala kunye nemveliso yeiilensi zoshishino, ezisetyenziswa kuzo zonke iinkalo zezicelo zoshishino. Ukuba unomdla okanye uneemfuno zeelensi zoshishino, nceda unxibelelane nathi ngokukhawuleza.
