Intaba ye-M12
Ukukhwezwa kwe-M12 kubhekisela ekukhwezweni kwelensi okujwayelekile okuvame ukusetshenziswa emkhakheni wezithombe zedijithali. Kuyifomu elincane lokukhweza lesici elisetshenziswa ngokuyinhloko kumakhamera ahlangene, amakhamera ewebhu, nezinye izinto zikagesi ezincane ezidinga amalensi ashintshashintshayo.
Intaba ye-M12 inebanga eligxilile le-flange elingu-12mm, okuyibanga eliphakathi kwe-flange ekhwezayo (indandatho yensimbi enamathisela ilensi ekhamera) kanye nenzwa yesithombe. Leli banga elifushane livumela ukusetshenziswa kwamalensi amancane nalula, okulenza lifaneleke kumasistimu amakhamera ahlangene futhi aphathekayo.
I-M12 mount ngokuvamile isebenzisa uxhumano olunentambo ukuvikela ilensi emzimbeni wekhamera. Ilensi ikrufulwe ekhamera, futhi imicu iqinisekisa ukunamathiselwa okuvikelekile nokuzinzile. Lolu hlobo lwezintaba lwaziwa ngobulula nokusebenziseka kalula.
Enye inzuzo ye-M12 mount ukuhambisana kwayo okubanzi nezinhlobo ezahlukene zamalensi. Abakhiqizi abaningi bamalensi bakhiqiza amalensi e-M12, anikezela ngobude bokugxila kanye nezinketho zokuvula ukuze avumelane nezidingo zesithombe ezihlukene. Lawa ma-lens ngokuvamile aklanyelwe ukusetshenziswa nezinzwa zesithombe ezincane ezitholakala kumakhamera ahlangene, amasistimu okuqapha, namanye amadivayisi.
C khuphuka
I-C mount iyisikhwezi selensi esimisiwe esisetshenziswa emkhakheni wamakhamera wevidiyo ochwepheshe namakhamera wesinema. Yaqala yasungulwa nguBell & Howell ngeminyaka yawo-1930s yamakhamera efilimu ayi-16mm futhi kamuva yamukelwa abanye abakhiqizi.
I-C mount inebanga eligxilile le-flange elingu-17.526mm, okuyibanga eliphakathi kwe-flange ekhwezayo kanye nenzwa yesithombe noma indiza yefilimu. Leli banga elifushane livumela ukuguquguquka ekwakhiweni kwamalensi futhi lenza ihambisane nezinhlobonhlobo zamalensi, okuhlanganisa womabili amalensi ayinhloko namalensi okusondeza.
Isikhwezi sika-C sisebenzisa uxhumano oluluchungechunge ukunamathisela ilensi emzimbeni wekhamera. Ilensi ikrufulwe ekhamera, futhi imicu iqinisekisa ukunamathiselwa okuvikelekile nokuzinzile. Intaba inobubanzi obuyi-intshi engu-1 (25.4mm), okuyenza ibe mncane uma iqhathaniswa nezinye izigaxa zamalensi ezisetshenziswa ezinhlelweni zamakhamera ezinkulu.
Enye yezinzuzo ezibalulekile ze-C mount ukuguquguquka kwayo. Ingakwazi ukuthwala izinhlobo ezahlukene zamalensi, okuhlanganisa amalensi efilimu angu-16mm, amalensi efomethi eyi-intshi engu-1, namalensi amancane aklanyelwe amakhamera ahlangene. Ukwengeza, ngokusetshenziswa kwama-adaptha, kungenzeka ukufaka amalensi okufaka i-C kwezinye izinhlelo zekhamera, ukwandisa ububanzi bamalensi atholakalayo.
I-C mount ibisetshenziswa kabanzi esikhathini esidlule kumakhamera wefilimu futhi isasetshenziswa kumakhamera esimanje edijithali, ikakhulukazi emikhakheni yezithombe zezimboni nezesayensi. Kodwa-ke, eminyakeni yamuva nje, amanye ama-lens afakwa njenge-PL Mount kanye ne-EF Mount avame kakhulu kumakhamera wesinema ochwepheshe ngenxa yekhono lawo lokuphatha izinzwa ezinkulu namalensi asindayo.
Sekukonke, ukukhwezwa kwe-C kuhlala kuyindawo ebalulekile futhi esebenza ngezindlela eziningi, ikakhulukazi ezinhlelweni lapho ukubumbana nokuvumelana nezimo kufunwa khona.
CS Mount
I-CS mount iyisikhwezi selensi esimisiwe esivame ukusetshenziswa emkhakheni wamakhamera wokugada nawokuvikela. Kuyisandiso se-C mount futhi yakhelwe ngokuqondile amakhamera anezinzwa zezithombe ezincane.
I-CS mount inebanga elifanayo lokugxila le-flange njenge-C mount, engu-17.526mm. Lokhu kusho ukuthi amalensi okokukhweza e-CS angasetshenziswa kumakhamera wokukhweza i-C ngokusebenzisa i-adaptha yokukhweza ye-C-CS, kodwa amalensi okufakwa kwe-C awakwazi ukukhwezwa ngokuqondile kumakhamera e-CS mount ngaphandle kwe-adaptha ngenxa yebanga elifushane lokugxila le-flange le-CS mount.
I-CS mount inebanga elincane lokugxila emuva kune-C mount, okuvumela isikhala esiningi phakathi kwelensi nenzwa yesithombe. Lesi sikhala esengeziwe siyadingeka ukuze kufakwe izinzwa zesithombe ezincane ezisetshenziswa kumakhamera agadayo. Ngokususa ilensi iqhele kude nenzwa, amalensi okukhweza e-CS alungiselelwa lezi zinzwa ezincane futhi anikeze ubude bokugxila obufanele kanye nokufakwa.
I-CS mount isebenzisa uxhumo oluluchungechunge, olufana nokokukhweza u-C, ukuze kunamathiselwe ilensi emzimbeni wekhamera. Nokho, idiameter yentambo yokukhweza i-CS incane kunaleyo ye-C mount, ikala u-1/2 intshi (12.5mm). Lo sayizi omncane ungolunye uphawu oluhlukanisa ukukhweza kwe-CS ku-C mount.
Amalensi okukhweza e-CS atholakala kabanzi futhi aklanyelwe ngokukhethekile izinhlelo zokusebenza zokugada nokuphepha. Banikeza izinhlobonhlobo zobude bokugxila kanye nezinketho zamalensi ukuze kuhlangatshezwane nezidingo ezihlukene zokugada, okuhlanganisa amalensi ane-engeli ebanzi, amalensi e-telephoto, namalensi e-varifocal. Lawa ma-lens ngokuvamile asetshenziswa ezinhlelweni zikamabonakude wesifunda esivaliwe (CCTV), amakhamera okuqapha amavidiyo, nezinye izinhlelo zokusebenza zokuphepha.
Kubalulekile ukuqaphela ukuthi amalensi e-CS mount awahambisani ngokuqondile namakhamera we-C mount ngaphandle kwe-adaptha. Nokho, ukuhlehla kuyenzeka, lapho amalensi okufakwa kwe-C angasetshenziswa kumakhamera e-CS mount ane-adaptha efanele.
