Tsananguro uye mutsauko pakati pe lens focal kureba, kumashure kwakatarisa kureba, uye flange chinhambwe ndeaya anotevera:
Focal Length:Hurefu hwakatarisana neparameta yakakosha pakutora mifananidzo nekuona izvo zvinoreva chinhambwe kubva pakati pekuona kwelenzi kuenda kundege yekufungidzira (kureva, ndege inonzwa kamera), inowanzoyerwa mumamirimita. Ichi chiyero chinoita basa rakakosha pakuona maonero uye ekufungidzira maitiro elens. Malenzi ane hurefu hwakasiyana-siyana anoenderana neakasiyana mafoto anodiwa uye mamiriro. Semuyenzaniso, malenzi ane hurefu hwakatarisa hupfupi, anowanzonzi marenzi-makona marefu, akanakira kutora zviono zvakakura senge zvivakwa zvezvivakwa kana nzvimbo huru. Aya lenzi anopa nzvimbo yakafara yekuona, achibvumira vatori vemifananidzo kuti vasanganise zvimwe zvinhu mukati mefuremu. Kune rimwe divi, kureba kwakajairwa, senge 50 mm, kwakasiyana-siyana uye kwakanyatsokodzera kutorwa kwemafoto-chinangwa. Ivo vanonyatsotevedzera ziso remunhu remusikirwo nzvimbo yekuona, zvichivaita sarudzo dzakanakisa dzemifananidzo, kutora mifananidzo yemumugwagwa, uye mazuva ese ekupfura. Sezvineiwo, marefu akatarisa kureba lenzi, anowanzozivikanwa sema telephoto lenzi, akagadzirirwa zvidzidzo zviri kure. Aya lenzi anodzvanya chinhambwe chinofungidzirwa pakati pezvinhu, zvichiita kuti zvive zvakakwana zvekutapa mhuka dzesango, zviitiko zvemitambo, kana chero chidzidzo chiri kure nemutori wemifananidzo.
Zvakakosha kucherechedza kuti kureba kwekutarisa hakungokanganisa munda wekuona chete asiwo kunokonzera kudzika kwemunda uye kukanganisa kwemufananidzo. Hurefu hwakapfupika hunowanzo gadzira mifananidzo ine hudzamu hukuru hwemunda uye kushoma kudzvanyirira, nepo kureba kwakarebesa kunokonzeresa kudzika kwemunda uye zvakanyanya kutaurwa kudzvanya mhedzisiro. Kunzwisisa hunhu uhwu kunobvumira vatori vemifananidzo kuti vasarudze iyo lens yakakodzera kune yavo chaiyo yekusika chiratidzo.
Back Focal Distance (BFD): Iyo yekumashure yakatarisa kureba, inozivikanwawo seyakatarisa kumashure kureba, inoyera chinhambwe kubva kumashure kweyekupedzisira lens element kuenda kundege yekufungidzira (kureva, kamera sensor ndege). Iyi parameter yakakosha mukugadzira lens uye kuita nekuti inobata zvakananga chimiro chemukati uye yemhando yemaziso yelens. Zvichienderana nehurefu hwekutarisa uye kushandiswa kwakagadzirirwa kwelens, iyo yekumashure yakatarisana kureba inogona kusiyanisa zvakanyanya. Semuyenzaniso, marenzi akafara-ekona kazhinji ane mapfupi ekudzokera kumashure madaro nekuda kwekugadzirwa kwawo kwemaziso, ayo anosanganisira kupeta mirazvo yemwenje pamakona akapinza kuti uwane nzvimbo yakafara yekuona. Mukupesana, telephoto lenses inoda kureba kumashure kwakatarisa madaro kuti agare akaomesesa marongero awo, ayo anosanganisira akawanda lens zvinhu kuti aderedze kukanganisa uye kuve nechokwadi kupinza mukati mese furemu.
Iyo yekumashure yakatarisana chinhambwe chinotarisawo nzvimbo yemuviri iripo yekuisa zvimwe zvinhu mukati melenzi, senge diaphragms, mafirita, kana kudzikamisa nzira. Iyo lens yakanyatsogadzirwa inofanirwa kudzikamisa kumashure kwakatarisa kure nezvimwe zvinhu zvakaita sehuremu, saizi, uye mutengo kuendesa kwakaringana kuita. Uyezve, iyo yekumashure yakatarisa kure inoita basa rakakosha mukuona kuenderana pakati pemalenzi nemitumbi yekamera, kunyanya kana uchishandisa akasarudzika adapta kana accessories.
Flange Distance:Iyo flange chinhambwe ndiyo imwe yakakosha parameter mukutora mifananidzo inomiririra chinhambwe kubva paflange pamusoro peiyo lens Mount interface (kureva, nzvimbo yekubatana pakati pelenzi nemuviri wekhamera) kune sensor ndege yekhamera. Ichi chiyero chakakosha pakuchengetedza kurongeka kwakaringana pakati pe lens uye sensor yekufungidzira, kuve nechokwadi chekutarisa kwakaringana uye kupinza mumifananidzo yakatorwa. Mukati meiyo yakafanana gomo sisitimu, ese kamera muviri uye lens zvinogovana yakafanana flange chinhambwe, ichivimbisa kusanganisa kusanganisa uye kuita kwakaringana. Nekudaro, akasiyana masisitimu ekumisikidza anogona kunge aine akasiyana marefu marefu, izvo zvinogona kuunza matambudziko paunenge uchiedza kushandisa lenzi dzakagadzirirwa imwe system pane kamera muviri kubva kune imwe system.
Masisitimu emazuva ano emakamera, kunyanya makamera asina girazi, anowanzo kuratidza mapfupi marefu madaro achienzaniswa neachinyakare DSLRs. Iyi sarudzo yekugadzira inopa akati wandei mabhenefiti, kusanganisira kugona kugadzira madiki, akareruka lenzi uye yakagadziridzwa optical performance nekumisa lens zvinhu padyo ne sensor. Pamusoro pezvo, makamera asina chionioni ane mapfupi flange madaro anogona kugarisa lenzi ane marefu marefu madaro kuburikidza nekushandisa adapta mhete. Aya maadapter anobvumira vatori vemifananidzo kuti vashandise akawanda akasiyana-siyana lenses, kuwedzera maitiro avo ekugadzira uye nekupa mukana kune akasiyana emeso maficha anogona kunge asiri kuwanikwa mumalenzi emazuva ano.
Kusiyana uye Kubatana Pakati Pazvo:
Tsanangudzo uye Yekuyeresa Point Misiyano: Imwe neimwe yeiyi paramita inoyera yakasarudzika chinhambwe chine chekuita nelens uye kamera system. Iyo yakatarisa kureba inoyera chinhambwe kubva panzvimbo yemaziso yelenzi kusvika kune ndege yekufungidzira, inomiririra yekutanga.
