Kodi lenzi yokhazikika yoyang'ana kwambiri ndi chiyani?

Monga momwe dzinalo likusonyezera,lenzi yokhazikikandi mtundu wa lenzi yojambulira zithunzi yokhala ndi kutalika kokhazikika, komwe sikungasinthidwe ndipo kumagwirizana ndi lenzi yojambulira zithunzi.

Ponena za izi, magalasi okhazikika nthawi zambiri amakhala ndi malo otseguka kwambiri komanso mawonekedwe abwino kwambiri, zomwe zimapangitsa kuti azigwiritsidwa ntchito pojambula zithunzi zapamwamba kwambiri.

Kusiyana pakati pa magalasi okhazikika ndi magalasi ozungulira

Lenzi yokhazikika yokhazikika ndi lenzi yozungulira ndi mitundu iwiri yodziwika bwino ya magalasi a kamera, ndipo kusiyana kwawo kwakukulu kuli ngati kutalika kwa focal kumatha kusinthidwa. Ali ndi ubwino wawo akagwiritsidwa ntchito m'njira zosiyanasiyana.

Mwachitsanzo, lenzi yokhazikika ndi yoyenera kugwiritsidwa ntchito m'malo okhala ndi kuwala kokwanira, kufunafuna chithunzi chapamwamba, komanso mitu yokhazikika yojambulira, pomwe lenzi yozungulira ndi yoyenera kwambiri pazochitika zomwe zimafuna zoom yosinthasintha, monga kujambula zithunzi zamasewera.

Lenzi yokhazikika yokhazikika

Kutalika kwa focal

Utali wa focal wa lens yokhazikika ndi wokhazikika, monga 50mm, 85mm, ndi zina zotero, ndipo sungasinthidwe. Lens yozungulira imatha kusintha kutalika kwa focal mwa kuzungulira kapena kukankhira ndi kukoka mbiya ya lens, zomwe zimathandiza kusankha pakati pa wide-angle ndi telephoto.

Omagwiridwe antchito a maso

Kawirikawiri,lenzi yokhazikikaIli ndi mawonekedwe abwino kuposa lenzi ya zoom chifukwa kapangidwe kake ndi kosavuta ndipo sikafuna kuganizira za kayendedwe ka lenzi kapena kapangidwe kake kovuta. Ponena za izi, ma lenzi okhazikika nthawi zambiri amakhala ndi malo otseguka kwambiri (okhala ndi F-value yochepa), zomwe zingapereke chithunzi chabwino, kuwala kwakukulu, komanso zotsatira zabwino zosokoneza maziko.

Koma tsopano ndi chitukuko cha ukadaulo, magalasi ena apamwamba kwambiri amathanso kufika pamlingo wa magalasi okhazikika pankhani ya magwiridwe antchito a kuwala.

Kulemera ndi kuchuluka

Kapangidwe ka lenzi yokhazikika ndi kosavuta, nthawi zambiri kakang'ono komanso kopepuka kukula. Kapangidwe ka lenzi yowonera zithunzi ndi kovuta, komwe kali ndi ma lenzi ambiri, kotero nthawi zambiri kumakhala kolemera komanso kwakukulu, zomwe sizingakhale zosavuta kwa ojambula zithunzi kugwiritsa ntchito.

Njira yowombera

Lenzi yokhazikika yokhazikikaMagalasi ndi oyenera kujambula zochitika kapena mitu inayake, chifukwa kutalika kwa focal sikungasinthidwe, ndipo magalasi oyenera ayenera kusankhidwa kutengera mtunda wojambulira.

Lenzi ya zoom ndi yosinthasintha pang'ono ndipo imatha kusintha kutalika kwa focal malinga ndi zosowa za kujambula popanda kusintha malo ojambulira. Ndi yoyenera pazochitika zomwe zimafuna kusintha kosinthasintha kwa mtunda ndi ngodya yojambulira.
