Ungasarudza Sei Lenzi Yakafara Yekuyera Paunenge Uchitora Nyeredzi?

Magirazi emakona akafarainopa nzvimbo yakakura yekuona, zvichikubvumidza kutora denga rehusiku rakakura uye ruzivo rwakaoma rweMilky Way paunenge uchitora mifananidzo yenyeredzi. Saka, unosarudza sei lenzi yakafara yakakodzera paunenge uchitora denga rine nyeredzi?

Kusarudza lenzi yekona yakafara yakakodzera kunoda kufunga nezvezvinhu zvakati wandei. Ngatitarisei zvinhu zvikuru zvinopesvedzera:

1.Sarudzo yehurefu hwefocal

Kureba kwe14-24mm ndiko kureba kwakanakisa kwemalenzi ane angle yakafara kutora mifananidzo yedenga rakazara nenyeredzi. Inogona kutora Milky Way yese uku ichiita kuti mufananidzo uve wakajeka, zvichiita kuti ive yakakodzera kutora mifananidzo yeMilky Way nenzvimbo dzinosanganisa minda yenyeredzi nenzvimbo dzakasiyana-siyana.

Semuenzaniso, kushandisa urefu hwe14mm kunokubvumira kutora mifananidzo yedenga rakakura uye kutora maonero akazara eMilky Way, nepo kushandisa urefu hwe24mm kunokubvumira kutora zvakawanda zvechiitiko chacho.

2.Sarudzo yevhudzi

Pakutora mifananidzo mudenga rine nyeredzi, zvakanakisisa kusarudza lenzi ine kona yakafara ine mukana wakakura, sezvo mukana wakakura une mukana wakakura munzvimbo dzisina chiedza chakawanda. Mukana wakafara unovimbisa kuti chiedza chinokwana, zvichidzivirira kufamba kwenyeredzi panguva imwe chete zvichibvumira ISO yakaderera—zvichideredza ruzha uye zvichiburitsa mifananidzo yakajeka uye yakachena.

Pakutora mifananidzo mudenga rine nyeredzi, zvinokurudzirwa kusarudza aperture yepamusoro yeF2.8 kana kupfuura. F2.8 ndiyo baseline yakakodzera nzvimbo zhinji, nepo F1.4-1.8 iriyo yakanakisisa uye yakakodzera nzvimbo dzisina chiedza chakawanda.

Pakutora mifananidzo yedenga rine nyeredzi negirazi rakafara, aperture inofanira kufungwa nezvayo

3.Kudzora kunaka kwemufananidzo

Magirazi emakona akafaraVane mukana wekukanganisika kwechromatic uye matambudziko ekukanganisika kwebharero; lenzi yakanaka inofanira kukwanisa kudzora kusachinja-chinja kwechromatic uye kukanganisa zvakanaka. Pakutora denga rakazara nenyeredzi, kana lenzi ikasadzora kusachinja-chinja kwechromatic zvakanaka, mativi epepuru anogona kuoneka akatenderedza nyeredzi, nepo kusachinja-chinja kuchaita kuti mufananidzo ukanganiswe, zvichikanganisa mhedzisiro yese.

Saka, zvakakosha kusarudza lenzi inoratidza kutonga kwepamusoro-soro pamusoro pekusachinja-chinja kwechromatic uye kukanganiswa. Pamusoro pezvo, zvakakosha kusarudza lenzi ine resolution yepamusoro kuti uve nechokwadi chekuti nyeredzi dzinoonekwa dzakajeka uye dzakapinza, kudzivirira kusviba.

4.Kutarisa kwakanyatsojeka nemaoko

Munzvimbo dzine rima, basa rekamera re autofocus rinowanzo shaya simba, zvichiita kuti pave nekugadzirisa focus nemaoko—kunyanya, kuisa focus ring pa infinity (∞). Zvisinei, zvakakosha kuziva kuti infinity mark pa distance scale ye lens inowanzo ratidza kusarongeka kudiki mukushanda uye haigone kuvimbwa nayo chete.

Saka, zvakakosha kusarudza lenzi ine damping iri pakati nepakati uye kufamba kwenguva refu kuti zvive nyore kugadzirisa focus uye kuve nechokwadi chekuti nyeredzi dzakajeka uye dzakapinza.

Kutora mifananidzo yedenga rine nyeredzi uchishandisa lenzi yakafara kunowanzoda kutarisisa nemaoko

5.Huremu uye vhoriyamu

Kana uchida kutakuralenziPanze kwenguva yakareba, unofanira kufunga nezvehuremu nehukuru hwelenzi yacho. Semuenzaniso, kana uchitakura zvishandiso zvemitambo yekunze zvinoda nguva yakareba, zvakaita sekukwira makomo kana kufamba netsoka, zvakakosha kusarudza lenzi ine dhizaini yakareruka kuitira kuti ugone kufamba wakareruka uye kuderedza mutoro wako.

Uyezve, zvakakosha kusarudza lenzi yakakodzera zvichienderana nebhajeti yako. Kana uine bhajeti yakawanda, unogona kusarudza lenzi yepamusoro-soro; zvisinei, kana bhajeti yako iri shoma, zvinowanzokurudzirwa kusarudza lenzi inosangana nezvinodiwa zvako zvekupfura.

Pfungwa Dzekupedzisira:

Kana muchida kutenga marudzi akasiyana-siyana emalenzi ekutarisa, ekuongorora, emadrone, epamba rakangwara, kana chero chimwe chinhu, tine zvamunoda. Taura nesu nhasi kuti udzidze zvakawanda nezvemalenzi edu nezvimwe zvinhu.
