一,Mhando dzeChengetedzo Kamera Lenses:
Kuchengetedza kamera lenses kunouya mumhando dzakasiyana, imwe neimwe yakagadzirirwa kukodzera chaiyo yekuongorora zvinodiwa. Kunzwisisa mhando dze lenses iripo kunogona kukubatsira kusarudza iyo yakakodzera kune yako yekuchengetedza kamera setup. Heano marudzi akajairika eChengetedzo kamera lenses:
1,Yakagadziriswa lens: Lens yakagadzirirwa ine imwe chete focal urefu uye munda wekuona, izvo hazvigone kuchinjwa. Iyo ndiyo sarudzo-inoshanda sarudzo yakakodzera kutarisisa imwe nzvimbo isina kudiwa kwekuenderera mberi kwekugadzirisa. Yakagadziriswa lenses inowanikwa mune dzakasiyana facal urefu, uchikubvumira kuti usarudze munda waunoda.
2,Varificeal Lens. Iyo inopa kuchinjika mukugadzirisa iyo zoom level uye yakanakira mamiriro ezvinhu apo nzvimbo yekutarisa inogona kuchinja kana kuti inoda huwandu hwakasiyana ruzivo. Varifceal Lenses inowanzoshandiswa mune zviitiko zvinopesana zvinodikanwa, zvakadai sekuongororwa kwekunze.
3,Zoom lens:Iyo zoom lens inopa kugona kugadzirisa iyo yekureba uye munda wewona kure kure. Inotendera ese ese Optical Zoom uye digital zoom. Optical zoom inochengetedza mufananidzo wemhando nekugadzirisa zvinhu zve lens, nepo digital zoom inowedzera iyo mufananidzo wacho, zvichikonzera kurasikirwa kwekugona kwemhando yemifananidzo. Zoom Lens anowanzo shandiswa mune zvekushandisa apo kure kure kutarisa uye kugona kwekutora zvakanaka ruzivo zvakakosha, senge muzvivakwa muhombe kana munzvimbo dzekunze.
4,Wide-Angle Lens: Level-angle lens ine ipfupi focal urefu, zvichikonzera munda wakawedzera Izvo zvakakodzera kutarisisa nzvimbo dzakakura kana nzvimbo dzakavhurika dzinotapa maonero akawandisa anokosha. Lever-angle lenses inowanzo shandiswa mukuongorora mamiriro ekuongorora akadai sekupaka mijenya, warehouse, kana kunze kwekunze kwekutarisa.
5,LEXPHOTE LENS. Izvo zvakanakira kutarisisa kwenguva refu kana mamiriro ezvinhu ipo panobata chaiyo nhoroondo kubva kure inokosha. Nhaurwa dzefoni dzinowanzoshandiswa pakushandisa mashandisirwo akadai sepa rezinesi rekuzivikanwa, kucherechedzwa kwechiso, kana kuongorora pfungwa dzakasimba kubva kure.
6,Pinile lens:Iyo PINHELE LEN ISINA LENTIONS LENS Icho Chinonyanya Kudiki uye Kungwara. Iyo yakagadzirirwa kuvanzika mukati mezvinhu kana nzvimbo, ichibvumira kuturikira kwekuvhara. Pinhole Lenses anowanzo shandiswa mumamiriro ezvinhu apo kamera inoda kuvanzika kana akangwara, senge muATMs, gonhi mapepa, kana kuvhara mashandiro ekuvhara.
二,Maitiro ekusarudza zvakanakisa lens kune yako yekuchengetedza kamera?
Kusarudza iyo yakanakisa lens yako yekuchengetedza kamera inhanho yakakosha mukuita kuti uite zvakaringana kuita uye kutapa yakakwirira-yemhando yepamusoro vhidhiyo yekufamba. Hezvino zvimwe zvinhu zvekufunga kana uchisarudza lens:
Kamera mhando:Sarudza mhando yekamera yekuchengetedza iwe kana kuronga kutenga. Mhando dzekamera dzakasiyana, dzakadai seBullet, dome, kana ptz (tilt-zoom), ingangoda marudzi akanyatso kana saizi.
Kureba kwehurefu: Kureba kwekureba kunosarudza munda wekuona uye huwandu hwe zoom. Iyo inoyerwa mumamirimita (mm). Sarudza urefu hwomukati hune ruzivo rwako chaidzo. Heano mamwe maitiro akajairika:
Wide-Angle Lens(2.8mm kusvika 8mm): Inopa munda wakawanda wekuona, wakakodzera kufukidza nzvimbo dzakakura kana kuongorora nzvimbo dzakakura.
Standard Lens (8mm kusvika 12mm): inopa maonero ane mwero akakodzera kuwanda kweiyo generallance application.
Telephoto Lens (12mm uye pamusoro): Inopa iyo Sarrower munda wekutarisa asi inopa yakakura zoom kugona kwekutarisa kwenguva refu kana kudzikama-kwakadzama.
Munda wekutarisa (FOV): Funga nezve nzvimbo iyo yaunoda kutarisa uye iyo nhanho yeruzivo inodiwa. Munda wakakura wokutarisa unobatsira munzvimbo dzakakura dzakavhurika, nepo iyo Narrower Fov iri nani kune yakatarwa nzvimbo dzekutarisirwa dzinoda kutarisisa.
Aperture. Iyo inomiririrwa neF-nhamba (semuenzaniso, f / 1.4, f / 2.8). Iyo yakaderera F-nhamba inoratidza kuparadzwa kwakawanda, kubvumira chiedza chimwe kuti upinde ma lens. Kuwedzeredzwa kwakapamhama kunobatsira mumamiriro akaderera emwenje kana kuti utore mifananidzo yakajeka murima.
Mufananidzo sensor kuenderana: Ita shuwa kuti lenzi inoenderana neiyo mufananidzo sensor saizi yako kamera. Zvakajairika mufananidzo sensor saizi inosanganisira 1/3 ", 1 / 2.7", uye 1 / 2,5 ". Uchishandisa lens yakagadzirirwa iyo yakakodzera sensor saizi inobatsira kuchengetedza mufananidzo wemhando uye zvinodzivirira kukuvara kana kufungidzira kwemifananidzo.
Lens mounT: Tarisa iyo lens gomo yemhando inodiwa kune yako kamera. Mhando dzeMakomo dzakajairika dzinosanganisira CS gomo uye c gomo. Ita shuwa kuti lenzi yaunosarudza inoenderana nekamera yekamera mhando.
Varificeal vs. akagadziriswa lens:Variflocal Lenses inokutendera kuti ugadzirise kureba kwenguva yakareba, kupa kuchinjika kuti uchinje munda wekuona sezvazvinodiwa. Yakagadziriswa lenses ine yakafanorongerwa focal urefu uye ipa munda wakatemwa wekutarisa. Sarudza mhando yakakodzera yakavakirwa pane yako yekuongorora zvinodiwa.
Budget:Funga nezve bhajeti rako kana uchisarudza lens. Yakakwirira-mhando lenses ine zvigadzirwa zvepamberi zvinogona kunge zvichidhura asi zvinogona kupa zviri nani mufananidzo mhando uye kusimba.
Mugadziri uye ongororo:Tsvagurudzo dzinokudzwa dzinobatsira dzinogona kuitika mumakamera ekuchengetedza kamera. Verenga revatengi ongororo uye tsvaga mazano kuti uve nechokwadi chekuti unosarudza yakavimbika uye ine mukurumbira chigadzirwa.
三,Kusarudza lens yeIndoor vs. Kunze: Ndeupi mutsauko?
Kana uchisarudza lens yeMukati kana kunze kwekuona, kune mashoma mashoma akasiyana ekufunga nekuda kwehunhu hwakasiyana hwezvinhu izvi. Hezvino zvaunoda kuti uzive:
Mamiriro Ekuvhenekera:Nzvimbo dzekunze dzinowanzove nemamiriro ezvinhu akasiyana-siyana, kusanganisira kupenya kwezuva, mimvuri, uye yakaderera-mwenje panguva yehusiku. Nzvimbo dzemukati, kune rumwe rutivi, kazhinji zvine mamiriro akaomeserwa mwenje nekuzvivharira. Naizvozvo, kusarudzwa kweLens kunofanirwa kufunga nezvezvinetso chaicho chega kwenzvimbo imwe neimwe.
Kunze:Sarudza lens ine yakarongedzwa yakarongedzwa (yakaderera f-nhamba) yekuunganidza imwe mwenje mumamiriro akaderera-mwenje. Izvi zvinovimbisa kuoneka kuri nani uye mhando yemufananidzo panguva yeDusk, mambakwedza, kana husiku hwehusiku. Pamusoro pezvo, Lenses neakanaka Dynamic Kugona kugona kunogona kubata musiyano uripo pakati pezuva rakajeka kwezuva uye nzvimbo dzakapetwa nenzvimbo zvinobudirira.
Indoor: Sezvo nzvimbo dzemukati dzinowanzove nemwenje unowirirana, ma lens zvine mwero kushungurudzwa zvine mwero kunogona kukwana. Lens ane zvishoma yepamusoro f-nhamba inogona kuendesa yakanaka mufananidzo mhando mumukati memukati miganho pasina kudikanwa kwekushanda kwakakura kwekuwedzera.
Munda weVatariri:Iyo inodiwa munda wekutarisa inogona kusiyana zvichienderana nehukuru uye chimiro chenzvimbo yekutarisa.
Outdoor: Nzvimbo dzekunze dzinowanzoda munda wakakura wekutarisa nzvimbo dzakakura zvakanyanya. Lever-angle lenses inowanzo shandiswa kutora pfungwa yakakura, kunyanya kune nzvimbo dzakavhurika sekupaka mijenya kana ekuvhara ekuvhara.
Indoor: Munda wekuona kwekutarisa kwemukati kunogona kusiyana zvichienderana nenzvimbo yakatarwa iri kutariswa. Mune zvimwe zviitiko, level-angle lens inogona kunge yakakodzera kuvhara imba yakakura kana horoway. Nekudaro, munzvimbo dzakasimba kana kuti pane zvakadzama kutarisisa zvinodiwa, lens neyekudzvanywa munda wekutarisa kana kugona kugadzirisa urefu hwehutsinye (Varificeal lens
Kupokana Kwemamiriro ekunze: Makamera ekunze ekunze uye lenses anofanirwa kugadzirwa kuti aregedze mamiriro ekunze mamiriro ekunze, akadai semvura, chando, guruva, kana kupisa kwakanyanya. Izvo zvakakosha kusarudza lenses zvakanyatsogadzirirwa kushandiswa kwekunze, izvo zvinowanzouya nemamiriro ekunze-anoramba maitiro kunge akasungwa ekudzivirira kubva pakunyorova uye marara.
Kupesana Kwavari:Munzvimbo dzekunze, pane njodzi yakakwira yekuparadza kana kushungurudzika. Funga nezvezvinyorwa zvine zvidziviriro zvekudzivirira senge zvinokanganisa-zvinodzivirira zvisingaite kana dombo kudzivirira kukuvara uye kuve nechokwadi chekuita kwekamera uye mhando yemhando yemifananidzo haina kukanganiswa.
Ir Kuenderana:Kana yako yekuongorora system inosanganisira infrared (IR) kuvhenekera kwehusiku chiratidzo, ona kuti lenzi inoenderana neIr mwenje. Dzimwe lenses dzinogona kunge dzive neyerin-yakatemwa shofita kuti uwedzere mufananidzo wemufananidzo mukati mezuva uchibvumira kuti ibudise Ir inovhenekera usiku.
