Chii chinonziLenzi yeFisheyeLenzi yefisheye rudzi rwelenzi yekamera yakagadzirirwa kugadzira maonero akafara echiitiko, ine kukanganiswa kwakasimba uye kwakasiyana. Lenzi yefisheye inogona kutora nzvimbo yakakura kwazvo yekuona, kazhinji kusvika kumadhigirii zana nemakumi masere kana kupfuura, izvo zvinobvumira mutori wemifananidzo kutora nzvimbo yakakura kwazvo yechiitiko mumufananidzo mumwe chete.

Lenzi yeziso refisheye

Magirazi eFisheye anopiwa mazita kubva pakukanganiswa kwawo kwakasiyana, izvo zvinogadzira mufananidzo wakatenderera kana wakaita sebharero unogona kuwedzeredzwa uye kurongwa. Kukanganiswa uku kunokonzerwa nenzira iyo lenzi inodzosera chiedza painopfuura nepakati pezvinhu zvegirazi zvakakombama zvelenzi. Izvi zvinogona kushandiswa nevanotora mifananidzo kugadzira mifananidzo yakasiyana uye inochinja-chinja, asi zvinogonawo kuva muganho kana mufananidzo wakaita sewechisikigo uchida.

Magirazi eFisheye anouya mumhando dzakasiyana-siyana, kusanganisira magirazi eFisheye akatenderera, magirazi eFisheye akachekwa-chekwa, uye magirazi eFisheye akakwana. Rudzi rumwe nerumwe rwemagirazi eFisheye aya rune hunhu hwarwo hwakasiyana uye rwakakodzera mhando dzakasiyana dzemifananidzo.
