M12 iNtaba
Ukunyuka kwe-M12 kubhekiselele kwi-lens ye-lens esemgangathweni esetyenziswa ngokuqhelekileyo kwintsimi ye-imaging yedijithali. Yifom encinci into yokunyuka esetyenziswa ikakhulu kwiikhamera ezidibeneyo, iikhamera zewebhu, kunye nezinye izixhobo ezincinci zombane ezifuna iilensi ezinokutshintshana.
Intaba ye-M12 inomgama ogxininise we-flange we-12mm, engumgama phakathi kwe-flange yokunyuka (intsimbi yentsimbi edibanisa i-lens kwikhamera) kunye ne-sensor yomfanekiso. Lo mgama omfutshane uvumela ukusetyenziswa kweelensi ezincinci kunye nezikhaphukhaphu, okwenza ukuba zilungele iinkqubo zekhamera ezidibeneyo kunye neziphathekayo.
Intaba ye-M12 ngokuqhelekileyo isebenzisa uqhagamshelo olunentambo ukukhusela ilensi kumzimba wekhamera. I-lens ikrwelwe kwikhamera, kwaye iintambo ziqinisekisa ukudibanisa okukhuselekileyo kunye nokuzinza. Olu hlobo lwentaba luyaziwa ngokulula kunye nokulula ukusetyenziswa.
Enye inzuzo yentaba ye-M12 kukuhambelana kwayo ngokubanzi kunye neentlobo ezahlukeneyo zeelensi. Abavelisi beelensi abaninzi bavelisa iilensi ze-M12, ezinikezela ngoluhlu lobude obugqalileyo kunye neenketho zokuvula ukuze zihambelane neemfuno zemifanekiso eyahlukeneyo. Ezi lens ngokwesiqhelo ziyilelwe ukuba zisetyenziswe kunye nemifanekiso emincinci yoluvo efunyenwe kwiikhamera ezixineneyo, iinkqubo zokucupha, kunye nezinye izixhobo.
C entabeni
Intaba ye-C yintaba yelensi esemgangathweni esetyenziswa kwibala levidiyo yobuchwephesha kunye neekhamera ze-cinema. Yaqala yaphuhliswa nguBell & Howell ngoo-1930 kwiikhamera zefilimu ze-16mm kwaye kamva yamkelwa ngabanye abavelisi.
Intaba ye-C inomgama ogxininise we-flange we-17.526mm, umgama phakathi kwe-flange ekhulayo kunye ne-sensor yomfanekiso okanye indiza yefilimu. Lo mgama umfutshane uvumela ukuguquguquka kuyilo lwelensi kwaye iyenze ihambelane noluhlu olubanzi lweelensi, kubandakanya zombini iilensi eziphambili kunye neelensi zokusondeza.
Intaba ye-C isebenzisa uxhulumaniso olunentambo ukuncamathisela ilensi kumzimba wekhamera. I-lens ikrwelwe kwikhamera, kwaye iintambo ziqinisekisa ukudibanisa okukhuselekileyo kunye nokuzinza. Intaba inobubanzi obuyi-intshi eyi-1 (25.4mm), eyenza ibencinci xa ithelekiswa nezinye iilensi zokuxhoma ezisetyenziswa kwiinkqubo ezinkulu zekhamera.
Enye yeenzuzo eziphambili zentaba ye-C kukuguquguquka kwayo. Iyakwazi ukwamkela iintlobo ezahlukeneyo zeelensi, kubandakanywa iilensi zefilimu ze-16mm, iilensi zefomathi ye-intshi ye-intshi, kunye neelensi ezincinci ezilungiselelwe iikhamera ezidibeneyo. Ukongezelela, ngokusetyenziswa kwee-adapters, kunokwenzeka ukukhupha iilensi ze-C kwezinye iinkqubo zekhamera, ukwandisa uluhlu lweelensi ezikhoyo.
I-C mount isetyenziswe ngokubanzi kwixesha elidlulileyo kwiikhamera zefilimu kwaye isasetyenziswa kwiikhamera zanamhlanje zedijithali, ngakumbi kwiinkalo zoshishino kunye nezenzululwazi. Nangona kunjalo, kwiminyaka yakutshanje, ezinye iilensi zokunyuswa njenge-PL Mount kunye ne-EF Mount ziye zaxhaphaka ngakumbi kwiikhamera ze-cinema yobuchwephesha ngenxa yokukwazi ukuphatha izinzwa ezinkulu kunye neelensi ezinzima.
Lilonke, i-C Mount ihlala iyilensi ebalulekileyo kwaye iguquguqukayo, ngakumbi kwizicelo apho ukubumbana kunye nokuguquguquka kunqweneleka.
CS Mount
Intaba ye-CS yintaba yelensi esemgangathweni esetyenziswa ngokuqhelekileyo kwibala lokujonga kunye neekhamera zokhuseleko. Kukwandiswa kwentaba ye-C kwaye yenzelwe ngokukodwa iikhamera ezinezinzwa zemifanekiso ezincinci.
Intaba ye-CS inomgama ogxilileyo we-flange ofanayo njenge-C mount, eyi-17.526mm. Oku kuthetha ukuba iilensi zokunyuka kwe-CS zingasetyenziselwa kwiikhamera ze-C ngokusebenzisa i-adaptha yokunyuka kwe-C-CS, kodwa iilensi ze-C zokunyuka azikwazi ukufakwa ngokuthe ngqo kwiikhamera ze-CS mount ngaphandle kwe-adaptha ngenxa yokufutshane komgama ogxininise we-flange we-CS mount.
Intaba ye-CS inomgama omncinci wokugxilwa ngasemva kune-C, ivumela indawo enkulu phakathi kwe-lens kunye ne-sensor yomfanekiso. Esi sithuba esongezelelweyo siyimfuneko ukulungiselela iinzwa zemifanekiso ezincinci ezisetyenziswa kwiikhamera zokucupha. Ngokuhambisa i-lens kude kude ne-sensor, iilensi ze-CS zilungiselelwe ezi zinzwa zincinci kwaye zibonelela ngobude obufanelekileyo kunye nokhuselo.
Intaba ye-CS isebenzisa uxhulumaniso olunentambo, olufana ne-C mount, ukuncamathisela i-lens kumzimba wekhamera. Nangona kunjalo, i-diameter yentambo ye-CS mount incinci kune-C mount, ilinganisa i-1/2 intshi (12.5mm). Lo bukhulu buncinci lolunye uphawu olwahlula i-CS entabeni ukusuka kwi-C mount.
Iilensi zokunyuswa kwe-CS ziyafumaneka ngokubanzi kwaye ziyilelwe ngokukodwa ukubekwa kweliso kunye nokhuseleko izicelo. Banikezela ngobude obahlukeneyo bojoliso kunye neenketho zeelensi ukuhlangabezana neemfuno ezahlukeneyo zokucupha, kubandakanywa iilensi ezibanzi, iilensi ze-telephoto, kunye neelensi zevarifocal. Ezi lensi zidla ngokusetyenziswa kwiinkqubo zikamabonakude (CCTV), iikhamera zokucupha ividiyo, kunye nezinye iinkqubo zokhuseleko.
Kubalulekile ukuqaphela ukuba iilensi zokunyuswa kwe-CS azihambelani ngokuthe ngqo neekhamera ze-C ngaphandle kweadaptha. Nangona kunjalo, i-reverse inokwenzeka, apho iilensi ze-C zinokusetyenziswa kwiikhamera ze-CS kunye ne-adapter efanelekileyo.
