Umusozi wa M12
Igikoresho cya M12 kivuga ku gikoresho gisanzwe gikoreshwa mu bijyanye no gufata amashusho mu buryo bwa digitale. Ni igikoresho gito gikoreshwa cyane cyane muri kamera nto, webcam, n'ibindi bikoresho bito by'ikoranabuhanga bisaba lenses zishobora guhindurwa.
Intera ya M12 ifite uburebure bwa mm 12, ikaba ari intera iri hagati y’impeta yo gushyiramo (impeta y’icyuma ifata lensi kuri kamera) n’icyuma gipima amashusho. Iyi ntera ngufi yemerera gukoresha lensi nto kandi zoroshye, bigatuma ikoreshwa neza kuri sisitemu nto kandi zishobora gutwara kamera.
Ubusanzwe, umugozi wa M12 ukoresha umugozi kugira ngo uhambire lens ku mubiri wa kamera. Lens ishyirwa kuri kamera, kandi imigozi ishyigikira ko ifata neza kandi ihamye. Ubwo bwoko bw'umugozi buzwiho ko bworoshye kandi bworoshye gukoresha.
Imwe mu nyungu z'iyi mount ya M12 ni uko ihura neza n'ubwoko butandukanye bw'ama lens. Abakora ama lens benshi bakora ama lens ya M12, batanga uburyo butandukanye bwo gupima no gupima kugira ngo ijyane n'ibikenewe bitandukanye byo gufata amashusho. Izi lens akenshi zigenewe gukoreshwa n'ama sensor mato y'amashusho aboneka muri kamera nto, sisitemu zo kugenzura, n'ibindi bikoresho.
Igikoresho cya C
Umusozo wa C ni umusozo usanzwe ukoreshwa mu bijyanye na kamera za videwo na sinema. Watangiye gukorwa na Bell & Howell mu myaka ya 1930 kuri kamera za filime za 16mm hanyuma ukaza kwemerwa n'abandi bakora.
Intera ya C mount ifite 17.526mm, ikaba ari intera iri hagati y’aho ifata n’icyuma gipima amashusho cyangwa filime. Iyi ntera ngufi ituma habaho ubworoherane mu gushushanya lens kandi bigatuma ihuzwa n’ama lens atandukanye, harimo lens za prime na lens zoom.
Igikoresho cya C gikoresha umurongo uhuza lens n'umubiri wa kamera. Lens ishyirwa kuri kamera, kandi imigozi ishyigikira ko ifata neza kandi idahindagurika. Igikoresho gifite umurambararo wa santimetero 25.4, bigatuma kiba gito ugereranyije n'ibindi bikoresho bya lens bikoreshwa muri sisitemu nini za kamera.
Kimwe mu byiza by'ingenzi bya C mount ni uburyo ikoresha mu buryo butandukanye. Ishobora kwakira ubwoko butandukanye bwa lens, harimo lens za filime za 16mm, lens za format ya 1-inch, na lens nto zagenewe kamera nto. Byongeye kandi, hakoreshejwe adaptateri, birashoboka gushyira lens za C mount ku zindi sisitemu za kamera, bikongera urwego rwa lens zihari.
Iyo C mount yakoreshejwe cyane mu bihe byashize kuri kamera za filime kandi iracyakoreshwa muri kamera za digitale zigezweho, cyane cyane mu bijyanye n'inganda n'ubumenyi. Ariko, mu myaka ya vuba aha, izindi lens mounts nka PL mount na EF mount zarushijeho kugaragara muri kamera za sinema z'umwuga bitewe n'ubushobozi bwazo bwo gufata sensor nini n'ama lens aremereye.
Muri rusange, C mount ikomeje kuba ingenzi kandi ifite ubushobozi bwo gukoresha lens nyinshi, cyane cyane mu bikorwa aho ari ngombwa ko irushaho kuba nto kandi yoroshye kuyikoresha.
CS Mount
CS mount ni lens mount isanzwe ikoreshwa cyane mu bijyanye na kamera zo kugenzura no kurinda. Ni inyongera ya C mount kandi yagenewe by'umwihariko kamera zifite sensors nto z'amashusho.
Ikirahure cya CS gifite intera imwe n’iya C mount, ikaba ari mm 17.526. Ibi bivuze ko lenzi za CS mount zishobora gukoreshwa kuri kamera za C mount hakoreshejwe adaptateri ya C-CS mount, ariko lenzi za C mount ntizishobora gushyirwa kuri kamera za CS mount zidafite adaptateri bitewe n’intera ngufi ya CS mount.
Igikoresho cya CS gifite intera ntoya inyuma ugereranyije n'igikoresho cya C, bigatuma habaho umwanya munini hagati y'ikirahuri n'icyuma gipima amashusho. Uyu mwanya w'inyongera urakenewe kugira ngo ushyiremo ibikoresho bito bipima amashusho bikoreshwa muri kamera zigenzura. Mu kwimura ikirahuri kure y'icyuma gipima, ikirahuri cya CS gipima amashusho gikoreshwa neza kuri ibyo bikoresho bito kandi gitanga uburebure bukwiye bw'igikoresho n'uburyo gikingira.
Igikoresho cya CS gikoresha umurongo uhuza imigozi, usa n'igikoresho cya C, kugira ngo gifatanye n'ikirahuri ku mubiri wa kamera. Ariko, umurambararo w'umugozi wa CS ni muto ugereranije n'uwa C, upima 1/2 santimetero (12.5mm). Ubu bunini buto ni ikindi kintu gitandukanya igikoresho cya CS n'igikoresho cya C.
Lense za CS mount ziraboneka cyane kandi zagenewe gukoreshwa mu kugenzura no mu mutekano. Zitanga uburyo butandukanye bwo gupima uburebure bw'inyuma n'amalenzi kugira ngo zihuze n'ibikenewe bitandukanye byo kugenzura, harimo lense zifite imiterere miremire, lense za telephoto, na lense za varifocal. Izi lense zikoreshwa muri sisitemu za televiziyo zifunze (CCTV), kamera zigenzura amashusho, n'izindi porogaramu z'umutekano.
Ni ngombwa kumenya ko lenzi zo gushyiramo CS zidahuye neza na kamera zo gushyiramo C zidafite adaptateri. Ariko, ibinyuranye n'ibyo birashoboka, aho lenzi zo gushyiramo C zishobora gukoreshwa kuri kamera zo gushyiramo CS zikoresheje adaptateri ikwiye.
