M12 phiri
Kukwera kwa M12 kumatanthawuza phiri la lens lokhazikika lomwe limagwiritsidwa ntchito pojambula zithunzi za digito.Ndi kachidutswa kakang'ono kamene kamagwiritsa ntchito makamera apang'ono, makamera apawebusayiti, ndi zida zina zazing'ono zamagetsi zomwe zimafuna magalasi osinthika.
Phiri la M12 lili ndi mtunda wokhazikika wa 12mm, womwe ndi mtunda pakati pa flange yokwera (mphete yachitsulo yomwe imamangiriza lens ku kamera) ndi sensa ya chithunzi.Mtunda waufupi uwu umalola kugwiritsa ntchito magalasi ang'onoang'ono komanso opepuka, ndikupangitsa kuti ikhale yoyenera pamakina ophatikizika komanso onyamula makamera.
Chokwera cha M12 nthawi zambiri chimagwiritsa ntchito chingwe cholumikizira kuti chiteteze mandala ku thupi la kamera.Lens imakulungidwa pa kamera, ndipo ulusiwo umatsimikizira kulumikizidwa kotetezeka komanso kokhazikika.Mtundu uwu wa phiri umadziwika chifukwa cha kuphweka kwake komanso kugwiritsa ntchito mosavuta.
Ubwino umodzi wa phiri la M12 ndikulumikizana kwake kwakukulu ndi mitundu yosiyanasiyana ya mandala.Opanga ma lens ambiri amapanga ma lens a M12, omwe amapereka utali wotalikirapo komanso pobowola kuti agwirizane ndi zosowa zosiyanasiyana zamaganizidwe.Ma lens awa amapangidwa kuti azigwiritsidwa ntchito ndi masensa ang'onoang'ono azithunzi omwe amapezeka mu makamera apang'ono, makina owunikira, ndi zida zina.
C phiri
C Mount ndi phiri lokhazikika la lens lomwe limagwiritsidwa ntchito popanga makanema apakanema ndi makamera amakanema.Idapangidwa koyambirira ndi Bell & Howell mu 1930s kwa makamera amafilimu a 16mm ndipo pambuyo pake adatengedwa ndi opanga ena.
The C phiri lili ndi flange focal mtunda wa 17.526mm, womwe ndi mtunda pakati pa flange okwera ndi sensa chithunzi kapena filimu ndege.Mtunda waufupi uwu umalola kusinthasintha pamapangidwe a lens ndikupangitsa kuti igwirizane ndi magalasi osiyanasiyana, kuphatikiza ma lens apamwamba ndi ma zoom.
Chokwera cha C chimagwiritsa ntchito kulumikizana kwa ulusi kuti amangirire lens ku thupi la kamera.Lens imakulungidwa pa kamera, ndipo ulusiwo umatsimikizira kulumikizidwa kotetezeka komanso kokhazikika.Phirili lili ndi mainchesi 1 inchi (25.4mm), zomwe zimapangitsa kuti likhale laling'ono poyerekeza ndi ma lens ena omwe amagwiritsidwa ntchito pamakamera akuluakulu.
Chimodzi mwazabwino zazikulu za C phiri ndi kusinthasintha kwake.Itha kukhala ndi mitundu yosiyanasiyana ya mandala, kuphatikiza magalasi amafilimu a 16mm, ma lens amtundu wa 1-inch, ndi ma lens ang'onoang'ono opangidwira makamera apang'ono.Kuphatikiza apo, pogwiritsa ntchito ma adapter, ndizotheka kuyika ma lens a C pamakina ena a kamera, kukulitsa ma lens omwe alipo.
Chokwera cha C chakhala chikugwiritsidwa ntchito kwambiri m'mbuyomu pamakamera amafilimu ndipo chimagwiritsidwabe ntchito m'makamera amakono a digito, makamaka m'mafakitale ndi zojambula zasayansi.Komabe, m'zaka zaposachedwa, ma lens ena okwera ngati PL mount ndi EF mount akhala akuchulukirachulukira mumakamera akatswiri amakanema chifukwa cha kuthekera kwawo kunyamula masensa akulu ndi ma lens olemera.
Ponseponse, phiri la C limakhalabe lofunikira komanso losunthika la lens, makamaka pamapulogalamu omwe kukhazikika komanso kusinthasintha kumafunidwa.
CS Mount
CS Mount ndi phiri la lens lokhazikika lomwe limagwiritsidwa ntchito poyang'anira makamera achitetezo.Ndiwowonjezera pa phiri la C ndipo amapangidwira makamera omwe ali ndi masensa ang'onoang'ono azithunzi.
Phiri la CS lili ndi mtunda wofanana wa flange monga phiri la C, lomwe ndi 17.526mm.Izi zikutanthauza kuti ma lens okwera a CS atha kugwiritsidwa ntchito pamakamera okwera C pogwiritsa ntchito chosinthira chokwera cha C-CS, koma ma lens okwera a C sangathe kuyikidwa mwachindunji pamakamera a CS mount popanda adaputala chifukwa cha mtunda wocheperako wa phiri la CS.
Chokwera cha CS chimakhala ndi mtunda wocheperako wakumbuyo kuposa phiri la C, zomwe zimalola kuti pakhale malo ochulukirapo pakati pa mandala ndi sensa yazithunzi.Malo owonjezerawa ndi ofunikira kuti agwirizane ndi masensa ang'onoang'ono azithunzi omwe amagwiritsidwa ntchito pamakamera owunika.Mwa kusuntha mandala kutali ndi sensa, ma lens okwera a CS amakometsedwa kwa masensa ang'onoang'onowa ndikupereka kutalika koyenera komanso kuphimba.
Kukwera kwa CS kumagwiritsa ntchito kulumikizana kwa ulusi, kofanana ndi phiri la C, kulumikiza lens ku thupi la kamera.Komabe, ulusi wa ulusi wa phiri la CS ndi wocheperako kuposa wa C phiri, wolemera 1/2 inchi (12.5mm).Kukula kocheperako ndi chikhalidwe china chomwe chimasiyanitsa phiri la CS ndi C phiri.
Ma lens okwera a CS amapezeka kwambiri ndipo amapangidwira kuti aziwunika komanso kugwiritsa ntchito chitetezo.Amapereka utali wotalikirapo komanso zosankha zamagalasi kuti akwaniritse zosowa zosiyanasiyana zowunikira, kuphatikiza ma lens akulu, ma telephoto lens, ndi ma lens osiyanasiyana.Magalasi awa nthawi zambiri amagwiritsidwa ntchito pamakina otsekera pawailesi yakanema (CCTV), makamera owonera makanema, ndi mapulogalamu ena achitetezo.
Ndikofunika kuzindikira kuti ma lens okwera a CS samagwirizana mwachindunji ndi makamera a C okwera opanda adaputala.Komabe, chotsaliracho ndi chotheka, kumene C mount lens angagwiritsidwe ntchito pa CS phiri makamera ndi adaputala yoyenera.
