Ibisobanuro no gutandukanya uburebure bwa lens, uburebure bwinyuma, nintera ya flange nibi bikurikira:
Uburebure bwibanze:Uburebure bwibanze ni ikintu gikomeye mu gufotora no muri optique bivuga intera iva hagati ya optique ya lens kugera ku ndege yerekana amashusho (ni ukuvuga indege ya sensor ya kamera), ubusanzwe bipimirwa muri milimetero. Iki gipimo kigira uruhare runini muguhitamo icyerekezo n'amashusho biranga lens. Lens ifite uburebure butandukanye bujyanye nibyifuzo bitandukanye byo gufotora. Kurugero, lens ifite uburebure bugufi bwibanze, bikunze kwitwa ubugari bugari, nibyiza gufata amashusho yagutse nkubwubatsi cyangwa ahantu nyaburanga. Izi lens zitanga umurongo mugari wo kureba, zemerera abafotora gushyiramo ibintu byinshi murwego. Kurundi ruhande, uburebure busanzwe bwibanze, nka mm 50, burahuza kandi bukwiranye no gufotora rusange. Barigana cyane aho amaso yumuntu asanzwe abona, bigatuma bahitamo neza kumashusho, gufotora kumuhanda, no kurasa burimunsi. Ibinyuranye, uburebure burebure bwibanze, busanzwe buzwi nka terefone ya terefone, bwagenewe amasomo ya kure. Izi lens zigabanya intera igaragara hagati yikintu, bigatuma ikora neza kugirango ifate inyamanswa, ibirori bya siporo, cyangwa ingingo iyo ari yo yose iri kure yuwifotora.
Birakwiye ko tumenya ko uburebure bwibanze butareba gusa umurima wo kureba ahubwo binagira ingaruka kumurambararo wumurima no kugoreka amashusho. Uburebure buke bwibanze bukunda kubyara amashusho hamwe nuburebure bwikibanza hamwe no kwikuramo bike, mugihe uburebure burebure bwibisubizo bivamo uburebure buke bwumurima hamwe ningaruka zigaragara zo kwikuramo. Gusobanukirwa ibi biranga bituma abafotora bahitamo lens ikwiranye nicyerekezo cyihariye cyo guhanga.
Intera Yinyuma (BFD): Intera yinyuma yinyuma, izwi kandi nkuburebure bwinyuma, ipima intera kuva hejuru yinyuma yibice byanyuma bya lens kugeza kumashusho yerekana amashusho (ni ukuvuga indege ya sensor ya kamera). Iyi parameter ningirakamaro mugushushanya no gukora kuko bigira ingaruka muburyo bwimiterere yimbere nubuziranenge bwa lens. Ukurikije uburebure bwibanze hamwe nuburyo bugenewe gukoresha lens, intera yinyuma irashobora gutandukana cyane. Kurugero, ubugari-bugari burigihe bufite intera ngufi yinyuma bitewe nubushakashatsi bwa optique, burimo kugoreka imirasire yumucyo kumpande zikarishye kugirango ugere kumurongo mugari wo kureba. Ibinyuranyo, lens ya terefone isaba intera ndende yinyuma kugirango ihuze neza na optique ya optique, ikubiyemo ibintu byinshi byerekana lens kugirango bigabanye aberrasi kandi byemeze ubukana kumurongo wose.
Intera yinyuma yerekana kandi umwanya ugaragara kugirango ushireho ibindi bikoresho imbere yinteguza, nka diafragma, muyungurura, cyangwa uburyo bwo gutuza. Lens yateguwe neza igomba guhuza intera yibanze hamwe nibindi bintu nkuburemere, ingano, nigiciro kugirango itange imikorere myiza. Byongeye kandi, intera yibanze yinyuma igira uruhare runini muguhuza lens hamwe numubiri wa kamera, cyane cyane iyo ukoresheje adaptate yihariye cyangwa ibikoresho.
Intera ya Flange:Intera ya flange ni ikindi kintu cyingenzi mugufotora cyerekana intera iva hejuru ya flange yubuso bwa lens mount (ni ukuvuga ubuso bwo guhuza hagati ya lens numubiri wa kamera) kugeza indege ya sensor ya kamera. Iki gipimo ningirakamaro mugukomeza guhuza neza hagati ya lens na sensor yerekana amashusho, byemeza neza kwibanda hamwe nuburemere mumashusho yafashwe. Muri sisitemu imwe yo kwishyiriraho, umubiri wa kamera hamwe na lens bisangiye intera imwe ya flange, byemeza guhuza hamwe no gukora neza. Nyamara, sisitemu zitandukanye zo kwishyiriraho zishobora kuba zifite intera zitandukanye, zishobora gutera ibibazo mugihe ugerageza gukoresha lens zagenewe sisitemu imwe kumubiri wa kamera kuva mubindi sisitemu.
Sisitemu ya kijyambere, cyane cyane kamera idafite indorerwamo, akenshi igaragaramo intera ngufi ya flange ugereranije na DSLR gakondo. Igishushanyo mbonera gitanga ibyiza byinshi, harimo nubushobozi bwo gukora utuntu duto, tworoheje kandi tunoze imikorere ya optique mugushira lens hafi ya sensor. Byongeye kandi, kamera idafite indorerwamo ifite intera ngufi ya flange irashobora kwakira lens ifite intera ndende ya flange ukoresheje impeta ya adapt. Izi adaptate zemerera abafotora gukoresha intera nini yumurage, kwagura ubushobozi bwabo bwo guhanga no gutanga uburyo bwihariye bwa optique budashobora kuboneka mumurongo ugezweho.
Itandukaniro n’ibihuza Muri bo:
Ibisobanuro no gupima Ingingo Itandukaniro: Buri kimwe muri ibyo bipimo gipima intera itandukanye ijyanye na lens na sisitemu ya kamera. Uburebure bwibanze bupima intera iva hagati ya optique ya lens kugera kumashusho yerekana amashusho, byerekana ibanze.
