analephera kuyang'ana mwatsatanetsatane nkhaniyo, komabe, zomwe zinayambitsa zochitika zambiri zomwe zinapezeka kuti zinalembedwa mwa 1758 ndi katswiri wa zamagetsi osiyanasiyana: John Dollond. Pogwiritsa ntchito 1763, Peter Dollard (mwana wa Yohane) adayambitsa kusintha kwa chipangidwe chomwe amachitcha kuti apochromat.

Chinthu chachikulu chotsatira m'kuunika chimene chinachitika chinali kusinthika kwa chiphunzitso chamakono cha kuwala; asayansi angapo, madokotala, akatswiri a sayansi, akatswiri, ndi akatswiri a masamu anaphatikizidwa mu kuyesera ndi kulingalira. Chochititsa chidwi kwambiri ndi Thomas Young (England) ndi AJ Fresnel (France), akukulitsa chidziwitso cha kuwala. James Clerk Maxwell (Scottish), omwe ali ndi mphamvu zamagetsi zowunikira ku 1864, pamodzi ndi ntchito yake pa zithunzi zoyambirira panthawi yomweyi (pafupi ndi 1860). Max Planck (Germany) ndi ake Quantum chiphunzitso cha 1900 chinathandiza kufotokoza kuwala; Albert Einstein (potsirizira pake United States) mu 1905 inapititsa patsogolo Mapark kufotokozera kuwala, kutitengera ife Photon.

Kupita patsogolo Quantum Ma mechanics anafotokoza zambiri za kuwala kwa 1935.

Ndi anthu onse owala kwambiri omwe amagwiritsa ntchito mfundo zenizeni, ndizofunika kuti musataye mtima wina woganiza bwino pogwiritsa ntchito lens. Carl Friedrich Gauss, katswiri wa masamu wa ku Germany, adathandiza kwambiri pa lens yamakono, komanso kumvetsetsa kwake. Wake Dioptrische Untersuchungen anatiphunzitsa zambiri, kuphatikizapo chiwongolero cha chiwongolero cha fano ndi Gaussian Optics.

Kwa zaka zotsatira za 100, ntchito yake inathandiza kutsogolera lens kupanga, makamaka kufotokoza kwa zipilala zisanu zazikulu mu mapuloteni (astigmatism, coma, kupotoza, mapulaneti a Petzval, ndi ozungulira).

Ngakhale kuti mawuwa agwiritsidwa ntchito pamaso a diso, amagwiritsidwa ntchito m'maganizo a optics, ndipo m'zinthu zonse zomwe zimafunikira lens kumaso (chithunzi) makamera ku magalasi a maso - zomwe zimatifikitsa ku lens zomwe zimagwiritsidwa ntchito masiku ano mu digito makamera avidiyo omwe amagwiritsidwa ntchito ndi malo osindikizira ndi ena odziwa ntchito.

Ndi makina a zoom 4.1x mu Super 35mm mawonekedwe, akuwongolera mofulumira kuti apange optic yothamanga. Canon zimakumanitsa nthawi zonse kapena zimadutsa miyezo yamakampani apamwamba. Ulemu nthawi zonse umakwatirana kuti ukhale nawo Canon mankhwala; mphete zothandizira zimathandiza kuti mukhale osakanikirana ndi mpeni pazitsulo izi ndi kumbuyo kwa flange njira yowonongeka ikukumana ndi zosowa za kanema. Lens ili lochititsa chidwi la 4K liri ndi lens lalikulu kwambiri komanso zopangidwa ndi fluorite zomwe zimathandiza kuwongolera zithunzi zake. Chifukwa cha luso labwino, kulingalira bwino kumafuna kusintha kokha. Mbali khumi ndi imodzi yokhala ndi chingwe chowombera chimapangitsa kuganizira kwakukulu.

Chotsimikizirika china chotsimikizika Canon ndi CN-E30-300mm T2.95-3.7 L SP (yomwe ili ndi PL PL kapena EF mount) - pamwamba pa Super 35mm mapangidwe ndi zopambana zosaneneka ndi telephoto focal kutalika. Zambiri mwazochitika mu CanonMapulogalamu apamwamba otsiriza amapeza njira zawo muzipangizo zawo zambiri; monga lenti yapitayi ichi, nayenso, chiri ndi zizindikiro zoonekera kumbali zonse za malo ozungulira kuti zitheke mosavuta kugwiritsa ntchito ngakhale kuchokera kumbali ina. Canon akatswiri amapanga makasitomalawo HD zoyembekeza mozama. Kupanga zojambula mu galasi kumaphatikizapo kufalikira ndi kuvomereza, kubwezeretsa zolakwika zomwe zimapangidwira chilengedwe.

Zomwe mafilimu athu akujambula ndi maulendo apamwamba, ma lens atithandizira kuwerengera chitukuko chathu chopitilira monga mpikisano wokhala ndi zithunzi zosavuta. Mapulogalamu mu telescopes angatibweretsere nyenyezi kuchokera kumwamba, ndi makilogalamu mu makamera athu angatithandize kutengera nyenyezi zathu kwa omvera athu.
