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 ncane uma iqhathaniswa nezinye izigaxa zamalensi ezisetshenziswa ezinhlelweni zamakhamera amakhulu.
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 kuyindlela 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 asetshenziswa ngokujwayelekile ezinhlelweni zikamabonakude ezivaliwe (CCTV), amakhamera okuqapha ividiyo, 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 we-CS mount nge-adaptha efanele.
