Hunhu uye Mamiriro Anoshanda eVarifocal Lens neFixed Focus Lens

Kana zvasvika pamagirazi emhando dzakasiyana, tinogona kuziva kubva muzita rayo kuti iyi i lenzi inogona kushandura urefu hwe focal, inova lenzi inoshandura chimiro chekupfura nekushandura urefu hwe focal pasina kufambisa mudziyo.

Pane kudaro, lenzi yekutarisa yakagadzika igirazi risingakwanise kuchinja urefu hwefocal, uye kana uchida kuchinja chimiro chekutora, unofanirwa kufambisa nzvimbo yekamera nemaoko.

1,Hunhu hwevarifocallenzi uyekutarisa kwakasimbalenzi

Tinogona kuona hunhu hwelenzi yevarifocal uye lenzi yefixed focus kubva pazita racho, uye tarisa zvakananga:

(1)Hunhu hwevarifocallenzi

A. Kureba kwefocal kunogona kuchinjwa, lenzi imwe chete inopa hurefu hwakasiyana-siyana hwefocal, inogona kuchinjika kune zvinodiwa zvakasiyana zvekupfura;

B. Maumbirwo ese akaomarara, kusanganisira mapoka akawanda e lenzi, lenzi inowanzova yakakura, yakakura zvishoma;

C. Saizi yeAperture inowanzova diki, izvo zvinoderedza kugona kupfura munzvimbo dzisina chiedza chakawanda;

D.Nekuda kwekugadzirwa kwakaoma kwelenzi, zvinogona kukanganisa kujeka uye kupinza kwemufananidzo;

E. Kuchinja urefu hwemagirazi kunobvisa zvakananga kudiwa kwekuchinja magirazi uye kunoderedza guruva netsvina zvinounzwa nekuchinja magirazi.

Lenzi ye varifocal

(2)Hunhu hwekutarisa kwakasimbalenzi

A. Kureba kwakatarwa chete, gadzirisa kureba kwakatarwa kunogona kungofambiswa nemaoko chete;

B. Chimiro chacho chiri nyore, chine magirazi mashoma, huremu hwakareruka, uye vhoriyamu diki;

C. Inogona kuva neburi rakakura uye inopfura munzvimbo dzine chiedza chakaderera;

D. Nekuda kwechimiro chayo chiri nyore, mifananidzo inowanzova yakajeka uye yakapinza.

Lenzi yekutarisa yakasimbiswa

2,Mamiriro ezvinhu anoshanda kunevarifocalmagirazi uyekutarisa kwakasimbamagirazi

Hunhu hwemagirazi emhando dzakasiyanauye magirazi ekutarisa akasimba anosarudza mamiriro avo akasiyana anoshanda:

(1)Mamiriro ezvinhu anoshanda kunevarifocalmagirazi

A. Kwekufamba: Lenzi imwe chete ye varifocal inokwana zvinodiwa zvakawanda.

B.Kutora mifananidzo yemuchato: Yakakodzera nzvimbo dzekupfura dzinokurumidza dzinoda kufukidza hurefu hwakasiyana-siyana hwefocal.

C. Inoshandiswa pakunyora mifananidzoSemuenzaniso, mune zviitiko zvakaita sekutora mifananidzo munhau zvinoda mhinduro nekukurumidza mumamiriro akasiyana-siyana,magirazi emhando dzakasiyanainogona kukurumidza kusiyanisa zvinhu kuti iwane zvinodiwa pakupfura.

Kutora mifananidzo yemuchato

(2)Mamiriro ezvinhu anoshanda kunekutarisa kwakasimbamagirazi

A. Zvekutora mifananidzo yezvigadzirwa: Lenzi yekutarisa yakagadzika inogona kuva nekushanda zvakanaka kwechiedza uye kudzora kunaka kwemufananidzo pakupfura mifananidzo isina kusimba.

B. Zvekutora mifananidzo mumugwagwa: Kushandisa lenzi yekutarisa yakagadzika kunomanikidza mufotori kuti afambe zvakanyanya uye kuti akwanise kutsvaga nzvimbo dzakanaka nemakona.

C. Kune mifananidzo yekugadzira: Zvakadai semifananidzo yemifananidzo, mifananidzo yenzvimbo, nezvimwewo, zvinogona kugadzira kudzika kwakanaka kwemhedzisiro yemunda kuburikidza neburi guru.

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.
