M12 Mount (s Mount) vs. C Mount vs. I-CS Mount

M12 Mount

I-M12 Mount isho i-lens evamile esetshenziswa kakhulu emkhakheni we-Digital imaging. Kuyinto encane yefomu lefomu elisetshenziswa ngokuyinhloko kumakhamera acwebile, ama-webcams, namanye amadivaysi amancane kagesi adinga ama-lens aguqukayo.

I-M12 Mount inebanga lokuqondwa kwe-flange le-12mm, okuyibanga phakathi kwe-flange ekhuphukayo (indandatho yensimbi enamathisela ilensi kwikhamera) kanye nenzwa yesithombe. Leli banga elifushane livumela ukusetshenziswa kwamalensi amancane futhi angasindi, okwenza lilungele izinhlelo zekhamera ezihambisanayo neziphathekayo.

I-M12 MATHER ngokuvamile isebenzisa uxhumano olunentambo ukuvikela ilensi emzimbeni wekhamera. Ilensi iklwebekile kwikhamera, futhi imicu iqinisekisa okunamathiselwe okuphephile nokuzinzile. Lolu hlobo lwentaba lwaziwa ngokulula nokusebenziseka kalula.

Ithuba elilodwa le-M12 Mount ukuhambisana kwalo okubanzi nezinhlobo ezahlukahlukene zelensi. Abakhiqizi abaningi be-lens bakhiqiza amalensi we-M12, enikeza uhla lwezinhlobo zobude obugxile kanye nezinketho zokusebenzisa i-aperture ukuze zivumelane nezidingo ezihlukile zokucabanga. Lawa ma-lens ajwayele ukuklanywa ukusetshenziswa ngezinzwa ezincane zezithombe ezitholakala kumakhamera acwebecwebe, izinhlelo zokubhekwa namanye amadivaysi.

C

I-C Mount iyinyumu yelensi evamile esetshenziswa emkhakheni wamakhamera wevidiyo ne-cinema. Kuqale kwakhiwa ngeBell & Howell ngawo-1930s kumakhamera wefilimu ayi-16mm futhi kamuva kwamukelwa abanye abakhiqizi.

I-C Mount inebanga lokuqondwa kwe-flange le-17.526mm, okuyibanga phakathi kwe-flange ekhuphukayo ne-sensor yesithombe noma indiza yefilimu. Leli banga elifushane livumela ukuguquguquka kwezimo ku-Lens Design futhi kwenza kube nokuhambisana nezinhlamvu eziningi zamalensi, kufaka phakathi amalensi aphambili namalensi wokusondeza.

I-C Mount isebenzisa uxhumano olunentambo ukuze unamathisele ilensi emzimbeni wekhamera. Ilensi iklwebekile kwikhamera, futhi imicu iqinisekisa okunamathiselwe okuphephile nokuzinzile. I-Mount ine-1-inch ububanzi (25.4mm), okwenza kube mincane ngokuqhathaniswa nokuqhathaniswa nezinye izikhala zelensi ezisetshenziswa ezinhlelweni zekhamera ezinkulu.

Enye yezinzuzo ezisemqoka ze-C Mount ukuguquguquka kwayo okuhlukahlukene. Ingahlalisa izinhlobo ezahlukahlukene zelensi, kufaka phakathi ama-lens wefilimu ayi-16mm, ama-lens wefomethi ye-1-inch, kanye namalensi amancane aklanyelwe amakhamera ahlanganisiwe. Ngokwengeziwe, ngokusetshenziswa kwama-adaptha, kungenzeka ukuthi abeke ama-C Mount Lens kwezinye izinhlelo zekhamera, andisa ububanzi bamalensi atholakalayo.

I-C Mount isetshenziswe kabanzi esikhathini esedlule kumakhamera wefilimu futhi isasetshenziswa kumakhamera wesimanje wedijithali, ikakhulukazi emasimini anemifanekiso yokucabanga ngezimboni nezesayensi. Kodwa-ke, eminyakeni yamuva nje, ezinye izikhala zelensi ezinjenge-PL Mount kanye ne-EF Mount ziye zanda kakhulu kumakhamera we-cinema ochwepheshe ngenxa yamandla abo okuphatha izinzwa ezinkulu namalensi aphezulu.

Sekukonke, i-C Mount ihlala i-lens ebalulekile neguquguqukayo, ikakhulukazi kuzinhlelo zokusebenza lapho kufiswa khona ukuhlangana nokuguquguquka.

I-CS Mount

I-CS Mount iyinyumu yelensi evamile esetshenziswa kakhulu emkhakheni wamakhamera wokubhekwa nokuvikeleka. Kuyisandiso se-C Mount futhi yakhelwe ngqo amakhamera anezinzwa ezincanyana zezithombe.

I-CS Mount inebanga elifanayo le-Flange Fortal njengentaba ye-C, okuyi-17.526mm. Lokhu kusho ukuthi ama-CS Mount Lens angasetshenziswa kumakhamera we-C Mount ngokusebenzisa i-adaptha ye-C-C-CS Mount, kepha amalensi we-C Mount angeke afakwe ngqo kumakhamera we-CS Mount ngaphandle kwe-adapter ngenxa yebanga elifushane le-flange lentaba ye-CS.

I-CS Mount inebanga elincane lokugxila emuva kunentaba ye-C, okuvumela isikhala esithe xaxa phakathi kwelensi kanye nesisindo sesithombe. Lesi sikhala esengeziwe siyadingeka ukwamukela izinzwa ezincane zezithombe ezisetshenziswa kumakhamera wokubhekwa. Ngokuhambisa ilensi kude ne-sensor, ama-lens weNtaba ama-CS alungiselelwe lezinzwa ezincane futhi anikeze ubude obufanele bokugxila nokumboza.

I-CS Mount isebenzisa uxhumano olunentambo, efana ne-C Mount, ukunamathisela ilensi emzimbeni wekhamera. Kodwa-ke, ububanzi bentambo ye-CS Mount incane kunaleyo yeNtaba ye-C, ukulinganisa 1/2 inch (12.5mm). Lolu usayizi omncane lungenye isimilo esihlukanisa i-CS Mount entabeni ye-C.

Ama-lens weNbumba le-CS atholakala kabanzi futhi yakhelwe ngokuqondile izicelo zokubhekwa kanye nokuphepha. Banikeza izinhlobo ezahlukahlukene zokugxila kanye nezinketho zelensi ukuze uhlangabezane nezidingo ezihlukile zokubhekwa, kufaka phakathi ama-lens ambi ama-angle, amalensi we-telephoto, namalensi we-varifocal. Lawa ma-lens asetshenziswa ngokujwayelekile ezinhlelweni zethelevishini ezivaliwe (CCTV), amakhamera wokubhekwa kwevidiyo, nezinye izinhlelo zokuphepha.

Kubalulekile ukuqaphela ukuthi ama-lens weNtaba ye-CS awahambelani ngqo namakhamera we-C Mount ngaphandle kwe-adaptha. Kodwa-ke, ukuphindisela kungenzeka, lapho amalensi we-C ama-C angasetshenziswa khona kumakhamera we-CS Mount nge-adaptha efanele.
