Kunyange zvazvo zvikamu zvizhinji zvekamera ye digital zvakakosha, lensi inogona kuva yakakosha zvikuru. Pasina lens yepamusoro, mapikicha ako haana mukana wekuve wakasimba uye wakajeka. Zvisinei, zvingava zvakaoma kududzira zvakananga zvakasiyana pakati pe lenses pasina kuziva mamwe mazwi emamera ekushandisa karojekiti zvakananga. Zvinogona kunge zvichinyadzisa kunzwisisa mamwe mazwi anowanzoshandiswa ne lenses.
Paunenge uchitenga kamera, iva nechokwadi chokuti unosarudza rudzi rwe lensi iyo ichashanda zvakanaka mumamiriro ako ezvinhu nokudzidza inonyanya kukosha kameri terminology.
- Zoom. Vamwe vatevedzeri vanotaura nezvekutsvaira sekukurisa kwechifananidzo, zvichiita kuti mufananidzo wacho apfure "chinyorwa" chisingabvumirwe kuswedera pedyo nehurukuro. Kunyange zvakadaro, tsanangudzo chaiyo yekutsvaira ndeyekwaniso ye lensi yekupfura pamatauriro akawanda. Mune mamwe mazwi, iyo zoom lens inogona kupfura yakareba pona pfuti kana kupururudza telephoto kana maviri. Hasi lenzi dzose dzinopa kuvhenekera.
- Kuratidzwa kwemaziso. Kugadzirwa kwemaziso ndiko kukwanisa kushandura urefu hwemiseu ye lens uchishandisa hardware mukati memwenje kuti uchinje urefu hukuru. Kuratidzwa kwemaziso ndiyo nzira inoshandiswa yekutsvaga, sezvo inenge isingabatsiri zvakanyanya kuratidzwa kwechifananidzo nekuda kwekutenderera kune hardware mu lens kuita shanduko. Kuratidzwa kwemaziso chinhu chinowanika nechagadziriswa lens cameras, pane DSLRs.
- Dhidhiro yeD Digital. Kudhindwa kweDhijito ndirwo rudzi rwekutsvaga iyo software mukati mekamera inoshandura iyo focal urefu kuburikidza nekukudzikisa chifananidzo. Nemhaka yekutsvaira kwema digital kunosanganisira kuwedzera kukura kwepikisiki, kuvhenekera kwejeri dzimwe nguva kunogona kuipa kuchinja kwechifananidzo. Paunenge uchitenga kamera, usaisa pfungwa pazhizha dze digital, sezvo vazhinji vanoona mifananidzo vanogona kudzokorora zvinhu zvakawanda zvekugadzira digital nekuita-post software. Ngwarira ku-optical zoom namba panzvimbo.
- Shandukari lenzi. Kumusoro-kuguma, kamera dze DSLR, uye mirrorless makamera zvinogona kushandisa lens inoshandurudzwa, apo lenzi dzakasiyana dzinopa hutano hwakasiyana. Nezvizhinji zve- DSLR lens uye mirrorless camera lens, kugadzirisa mufananidzo kunowanikwa mumutambo, kuvharira kamera kushungurudza nekuvandudza mifananidzo yemhando.
- Focal length. Nzvimbo yakatarisa ndeyekuyera kwemafaro kubva pakati pe lens kusvika kune imwe nzvimbo (iyo ndiyo inoratidzi yemifananidzo mune kamera kamera). Nhamba dzakawanda dzejeri dzemamera dzemakirini dzinoratidza lens 'inowedzera muyero yakareba, yakadai sa 25mm-125mm. Izvo zvakakosha urefu hwekuyera zvakanyatsorongedza telephoto uye yakakura-angle maikirwo e-lens kupfuura optical zoom measure, iyo inongori nhamba inoratidza chiyero pakati pekona yakareba uye telephoto chiyero. Muenzaniso uri pamusoro pe 25mm-125mm muenzaniso, unenge uine 5X optical zoom measurement.
- LCD. Iko-crystall display (LCD) iri kumashure kwekhamera ye digital inogona kushandiswa kugadzira mufananidzo, kufanana nekuona. Zvisinei, gara uchiyeuka kuti LCD haifaniri kunge yakasimwa 100% yemufananidzo iyo kamera ichapfura. LCD yakavhara dzimwe nguva inogona kuva 95% kana yakakwirira, uye purogiramu dzimwe nguva inoratidzwa mumashoko ekamera. Inowanzoenderana nemafungiro kuburikidza ne-lens, asi haikwanisi kuitanidza.
- Optical viewfinder. Iko optical viewfinder inopa kusati kusimbiswa, kusati kwedhijitariti yekuona kwemufananidzo mufananidzo wacho ari kuda kupfura. Uine pombi-shoma, pfungwa uye kupfura makamera, iyo optical viewfinder haisati yakasungirirwa kune lens optics - pane kudaro, inowanzova pamusoro pe-lens - zvinoreva kuti hazvizofananidzi zvakafanana nemifananidzo iyo lens ichapfura. Pamusoro-kuguma, makamera e DSLR anosungira optical viewfinder kune lens optics, achipa mufananidzo wakakwana wemifananidzo inouya.
- Electronic viewfinder (EVF). IEVF mukamera yemakambani iLCD duku inopa mufananidzo mukana wekugadzira mufananidzo wacho. IEVF inomiririra chimiro chechifananidzo. Nekutevedzera maonero kuburikidza ne lens yemufananidzo wekupedzisira, EVE inonyatsofananidza nekururama kweLCD.
