Kodi Mungasankhe Bwanji Lens Yokhazikika? Ndi Zinthu Ziti Zomwe Ziyenera Kuganiziridwa Mukamasankha?

A lenzi yokhazikikandi lenzi yokhala ndi kutalika kokhazikika, nthawi zambiri yokhala ndi malo otseguka kwambiri komanso mawonekedwe abwino kwambiri. Ndiye, kodi mungasankhe bwanji lenzi yokhazikika? Ndi zinthu ziti zomwe muyenera kuganizira posankha lenzi yokhazikika?

Posankha lenzi yokhazikika, zinthu zotsatirazi ziyenera kuganiziridwa mokwanira:

Fkutalika kwa maso

Kutalika kwa focal ndi chimodzi mwa zinthu zofunika kuziganizira posankha lenzi yokhazikika. Kutalika kwa focal kumatsimikiza momwe lenzi imaonekera, ndipo ma lenzi okhazikika a kutalika kosiyana ndi oyenera kujambula zithunzi ndi mitu yosiyanasiyana. Kutalika kwa focal kumaphatikizapo 50mm, 85mm, 35mm, ndi zina zotero.

Kawirikawiri, 50mm ndi kutalika kwa focal komwe kuli pafupi kwambiri ndi mawonekedwe a diso la munthu, koyenera kujambula zithunzi ndi zochitika za tsiku ndi tsiku; kutalika kwa focal kwa 85mm ndi kupitirira apo ndikoyenera kujambula zithunzi ndi zithunzi za telephoto; kutalika kwa focal komwe kuli pansi pa 35mm ndikoyenera kujambula malo okhala ndi ngodya yayikulu komanso zithunzi zachilengedwe.

Magalasi okhala ndi kutalika kosiyana ndi oyenera kujambula zochitika zosiyanasiyana

Mpata

Kukula kwa malo otseguka kumakhudza kuchuluka kwa kuwala komwe kumalowa mu lenzi ndi kuthekera kwake kulamulira kuya kwa malo.

Kawirikawiri, alenzi yokhazikikayokhala ndi malo otseguka kwambiri (monga F1.4, F1.8) imatha kujambula zithunzi zowoneka bwino m'malo opanda kuwala kochepa ndikupanga mawonekedwe abwino a kusokoneza kwa kumbuyo, komwe kuli koyenera pazithunzi ndi zithunzi zapafupi; lenzi yokhala ndi malo otseguka pang'ono (monga F2.8, F4) imakhala yokhazikika kwambiri pakulamulira kwakuya kwa malo ndi magwiridwe antchito a backlight, ndipo ndi yoyenera kujambula malo ndi nyumba zomwe zili ndi malo otseguka kwambiri.

Ubwino wa lenzi

Kuwonjezera pa kuyang'ana kwambiri kutalika kwa focal ndi kutsegula, muyeneranso kuganizira za ubwino wa lens posankha fixed-focus lens. Ubwino wa lens umaphatikizapo zinthu monga khalidwe la lens glass, lens covering, ndi focus motor.

Magalasi apamwamba kwambiri komanso kapangidwe ka ma lens angapereke chithunzi chabwino kwambiri komanso kubwerezanso mitundu, pomwe akuletsa kuchitika kwa zinthu zowoneka bwino monga kufalikira kwa ma lens.

Ubwino wa lenzi umakhudza ubwino wa chithunzicho

Kulemera ndi kuchuluka

Magalasi okhazikika nthawi zambiri amakhala opepuka kuposa magalasi owonera, koma alinso ndi kulemera ndi voliyumu inayake. Kulemera kwa lensi kudzakhudza mwachindunji zomwe ogwiritsa ntchito akukumana nazo.

Zipangizo zapamwamba komanso kulemera pang'ono zingathandize kuti lenzi ikhale yolimba komanso yosavuta kunyamula. Izi zitha kudziwika kutengera momwe mumagwiritsira ntchito komanso zosowa zanu zojambulira.

Mtengo

Mtengo wamagalasi okhazikikandi yotakata, kuyambira pamlingo woyamba mpaka waukadaulo. Mitengo ya magalasi amitundu yosiyanasiyana, mitundu ndi zofunikira zimasiyana kwambiri, nthawi zambiri kuyambira pa mayuan mazana angapo mpaka zikwi zingapo. Muyenera kusankha yomwe ikuyenererani malinga ndi bajeti yanu.

Sankhani lenzi yomwe ikuyenererani malinga ndi bajeti yanu

Kuphatikiza apo, posankha lenzi yokhazikika, muyeneranso kuganizira mtundu wa kamera yomwe mukugwiritsa ntchito komanso mawonekedwe a lenzi kuti muwonetsetse kuti lenziyo ikugwirizana ndi kamera.

Maganizo Omaliza:

Ngati mukufuna kugula mitundu yosiyanasiyana ya magalasi owunikira, owunikira, owunikira ma drone, nyumba yanzeru, kapena ntchito ina iliyonse, tili ndi zomwe mukufuna. Lumikizanani nafe lero kuti mudziwe zambiri za magalasi athu ndi zowonjezera zina.
