Yeyiphi eyona njongo iphambili yeelensi zokusebenza? Zeziphi iintlobo ze-lenses ezisetyenziswayo ezisetyenziswayo ezisetyenziswayo?

1,Yeyiphi eyona njongo iphambili yeelensi zokusebenza?

Iilensi zemizi-mvelisoNgaba iilensi zenzelwe izicelo zemizi-mveliso, isetyenziselwa ikakhulu uhlolo, ukwamkelwa komfanekiso kunye nokusetyenziswa komatshini wokusetyenziswa koomatshini kwizindlu zemveliso.

Iilensi zemizi-mveliso zineempawu zesisombululo esiphezulu, ukugqobhoza okuphantsi, kuthelekiswa nenqanaba eliphezulu kunye nombala ogqwesileyo. Banokubonelela ngemifanekiso ecacileyo nechanileyo ukuze bafezekise iimfuno zokuchongwa ezichanekileyo kunye nolawulo oluphambili kwimveliso yemizi-mveliso.

Iilensi zemizi-mveliso zihlala zisetyenziswa ngemithombo yokukhanya, iikhamera, isoftware yokulungisa umfanekiso kunye nezinye izixhobo zokufumana iziphene zemicimbi yemveliso, zilinganisa imilinganiselo, kunye nezinye iinkqubo zokuphucula ukusebenza kakuhle kunye nomgangatho wemveliso. Iilensi zemizi-mveliso zidlala indima ebalulekileyo kwinkqubo yemveliso yamashishini ahlukeneyo anjengeemoto, i-elektroniki, amayeza kunye nokutya.

2,Zeziphi iintlobo ze-lenses ezisetyenziswayo ezisetyenziswayo ezisetyenziswayo?

I-lens yemvelisolicandelo elibalulekileyo kwinkqubo yombono yomatshini. Owona msebenzi ophambili welensi yokumizi-mveliso yingcinga yokukhanya, edlala indima ebaluleke kakhulu kumgangatho wokucinga. Zininzi iintlobo zeelensi ezisetyenziswayo ezisetyenziswayo ezisetyenziswa kwimizi-mveliso ngokweendlela ezahlukeneyo zokuhlelwa.

①Ngokwendawo yobukumkani obunemizi-mveliso yezomzi-mveliso, banokwahlulwa ukuba:

A.I-C-Mounta le-Lens yeMizi-mveliso:Yilensi yezemizi-mveliso isetyenziswe ngokubanzi kwiinkqubo zombono zomatshini, ngeengenelo zobunzima bokukhanya, ubungakanani obukhulu, ixabiso eliphantsi kunye neentlobo ezahlukeneyo.

B.I-CS-Mounta le-Lens:Uqhagamshelo olunentambo lwe-CS-Mount luyafana ne-C-Mount, eyintsingiselo evunyiweyo yelizwe liphela. Iikhamera zeshishini ezine-CS-Mount inokuqhagamshelana kwi-C-Mound nakwiintaba ze-CS-Modes, kodwa ukuba iilensi ze-C-Motal zisetyenziswa, iringi kuphela ye-5mm iyafuneka; Ikhamera ye-C-Mota yeWecomu ayinakusebenzisa i-lenses ye-CS-Momes.

C.F-Intaba yemizi-mveliso Ilensi:F-Mount ngumgangatho wokujonga i-lens ezininzi zelensi. Ngokwesiqhelo, xa umphezulu wekhamera yemveliso mkhulu kune-intshi enye, ilensi ye-F-Mount iyafuneka.

②Ngokwemide eyahlukileyo yeIilensi zemizi-mveliso, banokwahlulwa ukuba:

A.Ilensi ejolise kuyo-gwenxa:Ubude obumiselweyo, ukungavisisani ngokubanzi, ukugxila kumsebenzi onqabileyo, umgama omncinci wokusebenza, kunye nendawo yokujonga iinguqu ze-angle kunye nomgama.

B.zoomIlensi yemizi-mveliso:Ubude obugxile bunokutshintshwa ngokuqhubekayo, ubukhulu bungaphezulu kwelensi yokugxila, efanelekileyo kwinjongo yotshintsho, kwaye umgangatho we-pixel awulunganga njengelensi ekugxilwe kuyo.

③Ngokwekokuba ubungakanani buguqukile, bunokwahlulwa ukuba:

A.I-LENS YOKUGQIBELA I-LENSI YOKUGQIBELA:Ukuqiniswa okusisigxina, umgama osisigxina wokusebenza, akukho subture, akukho sidingo sokutshintsha, izinga lokusebenza eliphantsi, linokusetyenziswa ngomthombo we-ceaxial.

B.I-Lens yokuqinisa i-lens yemveliso yemveliso:Ukuqiniswa kunokuhlengahlengiswa ngaphandle kokutshintsha umgama wokusebenza. Xa utshintsho olukhulu, lusazisa umgangatho obalaseleyo womfanekiso kwaye lube nolwakhiwo oluntsonkothileyo.

Iingcinga zokugqibela:

I-Chuangan iqhube uyilo lwangaphambili kunye nemveliso yeIilensi zemizi-mveliso, esetyenziswa kuwo onke amabakala kwizicelo zeshishini. Ukuba unomdla okanye unezidingo zeelensi zemizi-mveliso, nceda unxibelelane nathi ngokukhawuleza.
