Mbewu faktor.Chto ndi ndi n'kofunika posankha kamera yadigito.

Mbewu chinthu - mawu amene anawonjezera kuti dikishonare Zithunzi mawu zikamera ndi kugwiritsa ntchito kwambiri mbadwo watsopano wa kamera. Ndi chitukuko cha umisiri wamakono nzeru mu msika anayamba kuoneka zambiri digito SLR makamera ndi mtengo mosavuta nonprofessionals. ogula zimenezi, kuwonjezera pa mtengo, kusiyanitsa pokhapokha gulu lina, limene anasankha kamera - chiwerengero megapixels. Ndi megapixels iwo mwanjira asanaganize, ndi kupereka zingaoneke, ndichiyani akali kumvetsa kuti kwambiri chipangizo bwino. Komabe, monga kunapezeka, ina yofunika khalidwe zimasiyanitsa khalidwe pakati pa kamera yadigito, chinthu mbewu. Musanayambe kugula kamera, chilili kulingalira icho chiri.

Amateurs ochepa kamodzi mumadabwa bwanji, ngati mandala ndi mandala ali ndi mawonekedwe zozungulira, chimango nthawi yomweyo iwo kutenga amakona anayi? Palibe kumva yankho la funso ili palibe. Projecting fano yajambulidwa kwa atolankhani pa kamera, ndi Optics mandala chabe amadula "owonjezera" gawo la fano, kuwapatsa iwo mawonekedwe anayi. Ndi yabwino kwa kupanga filimu ongokhala mndandanda wa mafelemu amakona anayi, ndi kupanga zithunzi, ndi kupatsa ndi zina yaying'ono, ndi mosalekeza.

Chifukwa cha ntchito yaitali filimu zithunzi kukula kwa chimango pa filimu kupitiriza ntchito ngati kukula ndi Buku. Palibe ngakhale zimachokeradi kusintha ngakhale tsopano, pamene kuwombera pa filimu ndi pafupifupi chinthu chakale. Masiku ano, ndi inalowa la digito chithunzi kuwombera pa masanjidwewo wapadera, sipangakhalenso ziri poyerekeza ndi filimu.

Masanjidwewo, ndilo kukula kwa chimango lolingana film, wotchedwa anthawi chimango. Komabe, ambiri makamera digito SLR ndi bokosi ndi kakang'ono kwambiri. Mwachibadwa pa mawerengetsedwe otere chidwi yekha m'dera lapakati pa fano limene imakhoza kwa masanjidwewo m'ziwawa. Zowoneka, zikuwoneka ngati kujambulidwa ndi chimango mandala kukhala amayesetsa yaitali mogwirizana.

Choncho ananyamuka mawu akuti amasonyeza "zoonjezera" kutalika focal, amene si kwenikweni zikuchitika, chifukwa apa, monga chitsanzo chathu ndi magalasi yozungulira chabe kudula gawo lakunja la chimango lapansi. Mu English mawu "mbewu" (mbewu) likumasuliridwa kuti "kudula". Choncho dzina la mawu akuti - chinthu mbewu, amene amanena kuti ndi chongopeka kuchuluka Utali. Iwo limafotokoza molondola nthawi yomweyo Ndipotu pali ndondomeko kuwombera, monga mwa mphamvu ya thupi, kamera mandala Utali ndi sanasinthe, koma kusintha yekha mbali ya view.

Choncho, chimango zamitundu 35 timillimetrovoy filimu 24x36 mamilimita wakhala ndi akanali Buku lomwe tsopano chikugwirizana ndi chinthu mbewu. Kwa chimango amenewa ndi wofanana 1. Pa chiyambi cha chi, Nikon digito kujambula mwanzeru asankha kuti n'zotheka kubala digito SLR makamera ndi luso logwiritsa ntchito iwo ndi Optics akale, omwe anapangidwa kwa zaka zambiri ndipo nthawi zambiri ndalama zoposa kamera yokha.

Komabe, ndi kukhazikitsa mfundo imeneyi tili ndi vuto linalake. Pangani zonse kutalika kachipangizo anatsimikizira mtengo kwambiri, ndipo monga chochepa panalibe mfundo.

Chifukwa cha researches sensa wakhazikitsidwa, umene unali opendekera ndi nthawi theka zosakwana chimango 35 timillimetrovoy filimu. Choncho, kwa kachipangizo ngati 1.5 - izi ndi mbewu yake china. Canon, poyamba, anadzapeza njira bwino. Mbewu chinthu cha zipinda zake ungafanane 1.6.

Kuti mwanjira osiyana naye, mbewu chinthu cha Nikon anayamba kuitana DX, ndi zonse kutalika kachipangizo FX. kabisidwe amenewa akalipo lero. Izo ntchito ndi makampani ena ambiri, kuwonjezera Nikon.

Opanga makamera ndi chinthu mbewu, ntchito zimene m'dera masensa awo kubwera oposa theka. Zimenezi zinachititsa ndalama mu kupanga Optics wamphamvu ndi mtengo. Opanga anayamba kutulutsa zedi misa makamera digito ziti zomwe osiyanasiyana ojambula.
