I-M12 Mount
I-M12 mount ibhekisela ekufakweni kwelensi okujwayelekile okusetshenziswa kakhulu emkhakheni wezithombe zedijithali. Kuyi-fome factor encane esetshenziswa kakhulu kumakhamera amancane, ama-webcam, nakwamanye amadivayisi amancane kagesi adinga amalensi angashintshaniswayo.
I-M12 mount inebanga eliqondile le-flange elingu-12mm, okuyibanga eliphakathi kwe-flange yokufaka (indandatho yensimbi enamathisela ilensi ekhamera) kanye ne-sensor yesithombe. Leli banga elifushane livumela ukusetshenziswa kwamalensi amancane nalula, okwenza lifanelekele izinhlelo zekhamera ezincane neziphathekayo.
I-M12 mount ngokuvamile isebenzisa uxhumano olunezintambo ukubopha ilensi emzimbeni wekhamera. Ilensi ifakwa ku-screw ekhamera, futhi izintambo ziqinisekisa ukunamathela okuqinile nokuqinile. Lolu hlobo lwe-mount lwaziwa ngokulula kwalo kanye nokulula kokusebenzisa.
Enye inzuzo ye-M12 mount ukuthi ihambisana kakhulu nezinhlobo ezahlukene zamalensi. Abakhiqizi abaningi bamalensi bakhiqiza amalensi e-M12, anikeza ububanzi bobude obuqondile kanye nezinketho zokuvula ukuze kuhambisane nezidingo ezahlukene zesithombe. Lawa malensi ngokuvamile aklanyelwe ukusetshenziswa nezinzwa ezincane zesithombe ezitholakala kumakhamera amancane, izinhlelo zokuqapha, nakwamanye amadivayisi.
Isithasiselo se-C
I-C mount iyi-lens mount ejwayelekile esetshenziswa emkhakheni wamakhamera evidiyo nawesinema ochwepheshe. Ekuqaleni yathuthukiswa yiBell & Howell ngawo-1930 ngamakhamera efilimu angu-16mm futhi kamuva yamukelwa abanye abakhiqizi.
I-C mount inebanga eliqondile le-flange elingu-17.526mm, okuyibanga eliphakathi kwe-flange yokufaka kanye ne-sensor yesithombe noma i-film plane. Leli banga elifushane livumela ukuguquguquka ekwakhiweni kwelensi futhi lenza lihambisane nohlu olubanzi lwamalensi, kufaka phakathi amalensi amakhulu kanye namalensi okusondeza.
I-C mount isebenzisa uxhumano olunezintambo ukuze inamathisele ilensi emzimbeni wekhamera. Ilensi iboshwe nge-screw ekhamera, futhi izintambo ziqinisekisa ukunamathela okuqinile nokuqinile. I-mount inobubanzi obuyi-intshi engu-1 (25.4mm), okwenza ibe yincane uma iqhathaniswa nezinye izintambo zelensi ezisetshenziswa ezinhlelweni zekhamera ezinkulu.
Enye yezinzuzo ezibalulekile ze-C mount ukuthi iyakwazi ukuguquguquka. Ingamukela izinhlobo ezahlukene zelensi, okuhlanganisa amalensi efilimu angu-16mm, amalensi efomethi engu-1-intshi, kanye namalensi amancane aklanyelwe amakhamera amancane. Ngaphezu kwalokho, ngokusebenzisa ama-adapter, kungenzeka ukufaka amalensi e-C mount kwezinye izinhlelo zekhamera, kwandiswe ububanzi bamalensi atholakalayo.
I-C mount ibilokhu isetshenziswa kabanzi esikhathini esidlule kumakhamera amafilimu futhi isasetshenziswa kumakhamera edijithali anamuhla, ikakhulukazi emikhakheni yezithombe zezimboni nezesayensi. Kodwa-ke, eminyakeni yamuva nje, ezinye izikhonkwane zamalensi njenge-PL mount kanye ne-EF mount sezivame kakhulu kumakhamera e-cinema ochwepheshe ngenxa yekhono lazo lokuphatha izinzwa ezinkulu namalensi anzima.
Sekukonke, i-C mount isalokhu iyi-lens mount ebalulekile futhi eguquguqukayo, ikakhulukazi lapho kudingeka khona ukuqina nokuguquguquka.
I-CS Mount
I-CS mount iyi-lens mount ejwayelekile evame ukusetshenziswa emkhakheni wamakhamera okuqapha kanye nokuphepha. Iyisandiso se-C mount futhi yenzelwe ngqo amakhamera anezinzwa zesithombe ezincane.
I-CS mount inebanga elifanayo le-flange focal njenge-C mount, elingama-17.526mm. Lokhu kusho ukuthi amalensi e-CS mount angasetshenziswa kumakhamera e-C mount ngokusebenzisa i-C-CS mount adaptha, kodwa amalensi e-C mount awakwazi ukufakwa ngqo kumakhamera e-CS mount ngaphandle kwe-adaptha ngenxa yebanga elifushane le-flange focal le-CS mount.
I-CS mount inebanga elincane eliqondile ngemuva kune-C mount, okuvumela isikhala esiningi phakathi kwelensi nesensa yesithombe. Lesi sikhala esengeziwe siyadingeka ukuze kuhlangatshezwane nezinzwa zesithombe ezincane ezisetshenziswa kumakhamera okuqapha. Ngokuhambisa ilensi kude nesensa, amalensi e-CS mount alungiselelwe lezi zinzwa ezincane futhi anikeze ubude obufanele kanye nokumbozwa kwe-focal.
I-CS mount isebenzisa uxhumano olunezintambo, olufana ne-C mount, ukuze inamathisele ilensi emzimbeni wekhamera. Kodwa-ke, ububanzi bentambo ye-CS mount buncane kunobo be-C mount, bulinganiselwa ku-1/2 intshi (12.5mm). Lobu bukhulu obuncane bungenye isici esihlukanisa i-CS mount ne-C mount.
Amalensi okukhweza e-CS atholakala kabanzi futhi aklanyelwe ngqo izinhlelo zokusebenza zokuqapha nokuphepha. Anikeza izinketho ezahlukahlukene zobude obuqondile kanye nezinketho zamalensi ukuze kuhlangatshezwane nezidingo ezahlukene zokuqapha, kufaka phakathi amalensi ane-wide-angle, amalensi e-telephoto, namalensi e-varifocal. Lawa malensi avame ukusetshenziswa ezinhlelweni zethelevishini ezivaliwe (CCTV), amakhamera okuqapha ividiyo, kanye nezinye izinhlelo zokusebenza zokuphepha.
Kubalulekile ukuqaphela ukuthi amalensi okufaka i-CS awahambisani ngqo namakhamera okufaka i-C ngaphandle kwe-adaptha. Kodwa-ke, okuphambene nalokho kungenzeka, lapho amalensi okufaka i-C angasetshenziswa kumakhamera okufaka i-CS ane-adaptha efanele.
