Pokonza iris, iris nthawi zonse imakhala pamalo okulirapo.Pokhapokha pamene batani la shutter likanikizidwa kuti mutulutse chotsekacho, kabowo kameneka kamatsika pang'onopang'ono kupita ku f-factor, ndipo kabowoko kamabwereranso kumalo okulirapo pambuyo powonekera.

Kodi lens ndi chiyani?Lens ili ndi zala ziwiri mufilimu ndi kanema wawayilesi, imodzi imatanthawuza zigawo za kuwala zomwe zimagwiritsidwa ntchito ndi makamera a kanema ndi ma projekiti kuti apange zithunzi, ndipo amapangidwa ndi magalasi angapo.Mitundu yosiyanasiyana ya magalasi imakhala ndi mawonekedwe osiyanasiyana.Kugwiritsa ntchito kwawo pojambula zithunzi kumapanga njira yowonetsera;chachiwiri chikutanthauza chithunzi chosalekeza chotengedwa kuchokera ku mphamvu kupita ku mphamvu-kuzimitsa, kapena gawo pakati pa mfundo ziwiri zophatikizira , Zomwe zimatchedwanso ytterbium.Chala chimodzi ndi zala ziwiri ndi mfundo ziwiri zosiyana.Pofuna kusiyanitsa kusiyana pakati pa ziwirizi, imodzi imatchula lens ya kuwala ndipo awiriwo amatanthauza chithunzi cha lens.

Magalasi omwe amatchulidwa mufilimu ndi kanema wawayilesi si mandala akuthupi kapena owoneka, koma ndi mandala omwe amanyamula chithunzi ndipo amatha kupanga chithunzi.Lens ndi gawo lofunikira lomwe limapanga filimu yonse.Zithunzi zingapo zimapanga ndime kapena zochitika, ndipo ndime zingapo kapena zochitika zimapanga filimu.Chifukwa chake, mandala ndi gawo lofunikira la chilankhulo chowonekera.Ndilo maziko a nkhani ndi kafotokozedwe.Pojambula zithunzi ndi makanema apawailesi yakanema, lens imatanthawuza kuchuluka kwa gawo la zithunzi zojambulidwa ndi kamera kuyambira koyambira mpaka kuyima;pokonza pambuyo, mandala ndi zithunzi pakati pa mfundo ziwiri zosintha;mu filimu yomalizidwa, imodzi Lens imatanthawuza gawo lathunthu kuchokera ku kusintha kwapambuyo kwa kuwala kupita ku kusintha kwa kuwala kotsatira.

Ntchito yaikulu ya lens ndi kusonkhanitsa kuwala kowonekera kuchokera ku chinthu chowunikira ndikuchiyika pa CCD.Chithunzi chojambulidwa pa CCD ndi chozondoka.Dera la kamera liri ndi ntchito yobwezeretsanso, ndipo mfundo yake yojambula ndi yofanana ndi ya diso la munthu.

Gulu la magalasi:Malinga ndi chiyambi cha mandala, makamaka Japanese mandala ndi German mandala.Ma lens aku Japan nthawi zambiri amakhala ndi mtundu wabwinoko wopangika, ndipo ma lens aku Germany amakhala ndi lingaliro lamphamvu lakusanjika.Pamsika, magalasi aku China akukhala pamsika pang'onopang'ono, makamaka chifukwa mitengo yake ndi yotsika.
