Magirazi eVarifocalimhando yelenzi inoshandiswa zvakanyanya mukutora mifananidzo. Dzinogona kushandura kona yekupfura uye chimiro chayo nekugadzirisa kureba kwefocal, zvichibvumira lenzi imwe kutora mifananidzo yakasiyana-siyana pasina chikonzero chekuchinja malenzi kakawanda, nokudaro zvichiita kuti "lenzi imwe chete yezvinhu zvese".
1.Zvakanakira zvikuru zvevarifocalmagirazi
(1)Kugadzikana kwechimiro
Zvichienzaniswa nemalenzi ekutarisa akasimba, malenzi e-varifocal anogona kufukidza malenzi akawanda ekutarisa mulenzi imwe chete, zvichitora maonero akasiyana. Anobvumira kuchinja nekukurumidza kubva pakona yakafara kuenda kutelephoto pasina kuchinja malenzi, zvichiita kuti anyatsokodzera mamiriro ezvinhu anoda kugadziriswa nekukurumidza, senge kufamba uye kutora mifananidzo yezviitiko.
Semuenzaniso, kubva panzvimbo dzakakura kusvika pakuva pedyo nezvinhu zviri kure, kushandisa lenzi ye zoom kunongoreva kutenderedza mhete ye zoom, zvichikudzivirira kuti usapotsa nguva nekuchinja ma lenzi.
(2)Kutakurwa uye kushanda
Lenzi imwe chete ine ruvara rwakafara inogona kufukidza divi rakafara kusvika pakati nepakati, ichizadzisa zvinodiwa zvakasiyana-siyana zvekutora mifananidzo. Inogona kutsiva malenzi akawanda akasimba, ichideredza huremu hwekutakura uye nguva inopedzerwa uchichinja malenzi, zvichiita kuti ive yakakodzera mamiriro ezvinhu aunoda kufamba nechiedza, senge kutora mifananidzo mumugwagwa uye kufamba netsoka.
Semuenzaniso, pakutora mifananidzo mumugwagwa, lenzi ye telephoto inogona kushandiswa kutora nekukurumidza nzvimbo yeshiri inongoerekana yaonekwa iri mudenga kana chiitiko chiri kure, nepo lenzi ye wide-angle inogona kushandiswa kutora mifananidzo yevanhu vari pedyo.
Magirazi eVarifocal anopa kurongeka kunochinjika uye kushanda kwakanyanya
(3)Kugona kupfura zvine simba
Mukutora mifananidzo kwakasimba semavhidhiyo, ma lenzi ekuzoom anobvumira kugadziriswa kwe zoom ring nemaoko kana nemota kuti zoom in and out, zvichitungamira ziso remuoni, kugadzira zoom yakatsetseka yemafambiro ekamera, uye kutogadzira mhedzisiro yekugadzira. Semuenzaniso, kushandisa zoom lens kusunda zoom ring ne shutter speed inononoka kunogona kugadzira radial dynamic effect.
(4)Kurumidza kuchinja zvinoenderana nemamiriro ezvinhu ari kuchinja
Muzviitiko apo chiedza, nharaunda, uye nyaya zviri kuchinja nguva dzose, zvakaita sekutora mifananidzo mumugwagwa, kurekodha zviitiko, uye kufamba, ma lenzi e zoom anokutendera kuti ugadzirise nekukurumidza kutarisa kuti utarise mamiriro akasiyana pasina kuchinja ma lenzi nekukurumidza.
2.Varifocalmazano ekushandisa lenzi
Panguva iyomagirazi emhando dzakasiyanaZvinopa zvakawanda zviri nyore uye rusununguko rwekugadzira mifananidzo, hunyanzvi hwekushandisa hunodiwa kuti uburitse kugona kwavo kwakazara.
(1)Enzanisa urefu hwakasiyana hwenzvimbo zvichienderana nenzvimbo
Kushandisa urefu hwakasiyana hwemafocal kunogona kuburitsa mhedzisiro dzakasiyana dzemifananidzo, uye nzvimbo dzakasiyana dzinodawo hurefu hwakasiyana hwemafocal. Semuenzaniso:
Magirazi ane makona akafara akakodzera kutora mifananidzo yenzvimbo nezvivakwa, zvichisimbisa maonero nehupamhi hwenzvimbo, asi kungwarira kunofanira kuitwa kudzivirira kukanganisa pamipendero yemufananidzo;
Marefu akajairika akakodzera kutora mifananidzo yemumugwagwa uye kutora mifananidzo yemifananidzo, zvichipa maonero ehupenyu hwezuva nezuva ukuwo zvichifungawo nezvenharaunda, zvichiita kuti zvikodzere kutora mifananidzo yezvinyorwa, nekudzvanywa kwechisikigo uye kusviba kwemashure kwakapfava;
Magirazi eTelephoto akakodzera kutora mifananidzo yemhuka dzesango nemitambo, zvichibvumira kutora mifananidzo kure uku uchidzivirira kupindirana nemunhu ari kutorwa, kutora zvinhu zviri kure, uye kubvisa zvinhu zvakati wandei kuti zviratidze munhu ari kutorwa.
Magirazi eVarifocal anogona kuenzaniswa nehurefu hwakasiyana hwema focal zvichienderana nenzvimbo yacho
(2)Kutarisa nekutarisa kwenguva refu
Paunenge uchishandisa lenzi ye varifocal, tanga watarisa kure kure ne telephoto, wobva wasarudza kureba kwakakodzera kuti utore. Izvi zvinovandudza kunyatsoona kwakakodzera. Pakure kure ne telephoto, mufananidzo wemunhu wacho wakakura nepo kudzika kwemunda kuri kudiki, zvichiita kuti zvive nyore kuona kwakarurama. Izvi zvinobatsira zvikuru mumamiriro emwenje ane chiedza chekumashure kana akaomarara, uko kushandisa lenzi ye telephoto kunobvumira kuyerwa kwakakodzera kwenzvimbo.
(3)Usanyanya kuvimba ne zoom,dzivisa kuumbwa kweune usimbe
Zviri nyore kushandisamagirazi emhando dzakasiyanazvinogona kutungamira nyore nyore kune nzira isina kugadzikana, ichingovimba nekutenderedza zoom ring kuti igadzire mapikicha, zvichikonzera kuvimba zvakanyanya ne zoom uye zvingangoderedza kutanga kwekugadzirwa. Zvakakosha kucherechedza kuti kuchinja urefu hwe focal ye lens kunochinja nzvimbo yekuona, ukuwo kufambisa kamera kuchichinja maonero.
Kufambisa kamera pedyo kana kure kunogona kugadzira mhedzisiro yakasiyana-siyana yenzvimbo uye kudzvanywa kwemashure. Nokudaro, kushandisa lenzi yevarifocal kunoda kufamba-famba kuti uwane kona yekupfura yakakodzera uye wobva wagadzirisa urefu hwefocal kuti ugadzire mifananidzo yemhando yepamusoro.
(4)Teereraiiyokugadzikanayemagumo eterefoto
Malenzi eTelephoto anowanzo zungunuswa nekamera, zvichikonzera mifananidzo isina kujeka. Muzviitiko zvakadaro, zvinodikanwa kuwedzera kumhanya kweshutter kana kushandisa maturusi ekusimbisa mufananidzo. Kunyanya kana uchishandisa malenzi evarifocal ane urefu hwe200mm kana kupfuura, zvinokurudzirwa kushandisa tripod kana mudziyo wakafanana kuti usimbise lenzi. Izvi zvinoderedza kuzungunuswa kwepfuti kunoitwa nemaoko, zvinoita kuti kupfura kugadzikane, uye zvinovandudza kupinza kwemufananidzo.
Kugadzikana kwakakosha zvikuru pakupfura ne lenzi ye telephoto
(5)Teererai kuchinja kwenzvimbo inovhurika uye kudzika kwenzvimbo.
Kuvhurika kwakanyanya kwema lenzi mazhinji ekuzoom kunoderera sezvo urefu hwefocal huchiwedzera. Izvi zvinoreva kuti pamagumo e telephoto, kuvhurika kwakanyanya kunenge kudiki, zvichideredza huwandu hwechiedza chinopinda mu lenzi uye zvichideredza kuvhurika kwekumashure. Saka, mumamiriro ezvinhu asina chiedza chakawanda kana kana zvichidikanwa kuvhurika kwakasimba kwekumashure, shandisa magumo e lenzi akafara kana kuwedzera ISO.
Kuti pave nemhedzisiro yakakura yebokeh pamagumo etelephoto, panogona kudiwa mukana wakakura kana daro riri pedyo rekupfura. Uyezve, kuti udzore kudzika kwemunda, unogona kuyedza kunzwisisa kukanganiswa kwehurefu hwakasiyana hwefocal pahurefu hwemunda. Semuenzaniso, kupfura neurefu hupfupi hwefocal wozowedzera mukati kunogona kuita kuti kumashure kuve kwakapinza, nokudaro kuwana kudzika kwakanyanya kwemunda.
(6)Shandisa hood yelenzi zvine musoro
Magirazi eVarifocalvane chimiro chakaoma kunzwisisa uye boka guru remalenzi epamberi, zvichiita kuti vabatwe nechiedza chisingawanikwe, izvo zvinogona kukonzera kupenya kwechiedza uye kupenya kwechiedza. Kushandisa lenzi hood kwakakosha mukuderedza mhedzisiro iyi yekupenya kwechiedza; kushandisa lenzi hood chaiyo kunogona kuvandudza kunaka kwemufananidzo nekusiyana kwawo, nokudaro zvichiwedzera kunaka kwemufananidzo.
(7)Shandisa mafirita nekungwarira
Hazvikurudzirwi kushandisa mafirita pamalenzi ekuzoom kunze kwekunge zvichidikanwa. Mune dzimwe nzvimbo, dzakadai semahombekombe egungwa kana munzvimbo dzine mvura yemunyu, mafirita ekudzivirira kana ekudzivirira anogona kushandiswa, asi kushandisa mamwe mafirita kunongowedzera matambudziko echiedza mukati melenzi, izvo zvinogona kukonzera matambudziko.
Paunenge uchishandisa lenzi ye varifocal, nyatsoteerera mashandiro echiedza
Pamusoro pezvo, zviitiko zvakasiyana zvekutora mifananidzo zvinoda matekiniki akasiyana pakushandisa varifocal lenses. Semuenzaniso, mukutora mifananidzo yekufamba, zoom lens inogona kufukidza wide-angle kusvika telephoto mune rimwe lenzi; aperture diki inogona kushandiswa kutora mifananidzo yenzvimbo masikati, nepo telephoto lens yepakati ine aperture hombe inogona kushandiswa kutora mifananidzo yemumugwagwa panguva yemanheru.
Mukupedzisa,magirazi emhando dzakasiyanainopa mukana wekugadzira zvinhu zvitsva, ichitsigira vanhu vanoda kutora mifananidzo. Zvisinei, semutori wemifananidzo, kungoziva matekiniki e varifocal lens hakuna kukwana; kudzidzira kwakawanda uye ruzivo rwekushanda nesimba zvakakosha kuti uchinje hunyanzvi uhwu kuita intuition, zvichikubvumidza kushandisa zvizere mabhenefiti e zoom lenses uye kubata zviitiko zvakasiyana-siyana zvehunyanzvi zviri nyore.
