2) Lens ya Photomic niyihe?
Lens Phons azwi kandi nka "Lenstonsiya". Dukurikije ihame ryo guhindura isomo ryumucyo, lens irashobora kwicwa vuba na mirasi ya ultraviolet, guhagarika urumuri rukomeye kandi rukurura urumuri rwa ultraviolet, hanyuma ugaragaze urumuri rwaltraviolet, hanyuma ugaragaze urumuri rwaltraviolet, hanyuma ugaragaze urumuri rudafite aho rudafite aho ruva mu itara rigaragara. Subira mu mwijima, urashobora kugarura byihuse leta idafite ibara, menya ko lens yacika. Ibara rero rihinduka lens rikwiranye no gukoresha mu nzu no hanze icyarimwe, gukumira urumuri rw'izuba, urumuri rw'izuba, rukagirana ku byangiritse ku jisho.
