Nqampuna faktor.Chto kuba futhi Yeka ukuthi kubaluleke kangakanani lapho ukhetha ikhamera yedijithali.

Nqampuna isici - igama sengezwe imigomo isichazamazwi enezithombe ukuvela ukusetshenziswa kabanzi isizukulwane esisha amakhamera. With ukuthuthukiswa ubuchwepheshe yesimanje ezintsha emakethe yaqala ukubonakala ezingasho digital SLR amakhamera ngezindleko kufinyeleleke nonprofessionals. abathengi okunjalo, ngaphezu intengo, ukuhlukanisa ngaphandle kwesinye isigaba, okuyiwona ikhamela ekhethiwe - inombolo megapixels. Nge megapixels ngandlela-thile ziye esiphethweni, nekwetfula ngalokwanele, kuyini ngempela namanje ukuqonda ukuthi xaxa kudivayisi kangcono. Nokho, kwacaca ukuthi, esinye futhi isici mfanelo ebalulekile esiwuphawu phakathi ikhamera yedijithali, isitshalo isici. Ngaphambi kokuba uthenge ikhamera, ukuma ukuthola ukuthi iyini.

Bambalwa nayizimfundamakhwela okungenani kanye wazibuza ukuthi kungani, uma lens kanye lens has simise isiyingi, uzimele ngesikhathi esifanayo bathatha unxande? Ayikho into elukhuni e impendulo yalo mbuzo ingucha. Projecting isithombe izithombe nabezindaba e ikhamera, yokukhanya lens umane ezinquma ingxenye "extra" yesithombe, wasinikeza a ukuma elingunxande. Kuyinto elula kakhulu ukwenziwa ifilimu ehlanganisa uchungechunge ozimele elingunxande, futhi ngokwenza izithombe, nokunikela nezinye compact, futhi enza izinto ezihlukahlukene.

Ngenxa ukusetshenziswa kwesikhathi eside ifilimu izithombe ubukhulu ifreyimu phezu ifilimu siqhubeke ingasetshenziswa njengendlela usayizi inkomba. Akekho ngisho ingekho ukuyiguqula ngisho namanje, lapho ngokudubula ku ifilimu cishe into yesikhathi esidlule. Namuhla, ne ukubusa digital isithombe sigameko sokudubula matrix ekhethekile, okungase cishe kuqhathaniswa ne-ifilimu.

Matrix, okuyinto ubukhulu okuhambisanayo ifilimu Uhlaka, ngokuthi Uhlaka esigcwele. Nokho, iningi digital SLR amakhamera kuyinto matrix nge usayizi ezincane kakhulu. Ngokwemvelo ku matrices esinjalo umxhwele kuphela endaweni emaphakathi yesithombe ukuthi wayeyoke afike matrix ngokugcwele. Ngokubukeka, kubukeka sengathi izithombe ngumuntu Uhlaka lens abanesimo ubude isikhathi eside eqondile.

Yingakho kuphakama le nkulumo ichaza "ukwanda" ubude ebalulekile, okuyinto ayenzeki ngempela, ngoba lapha, njengakwezinye izinto isibonelo sethu abanamalensi round, umane anqunywe engxenyeni engaphandle ifremu. NgesiNgisi igama elithi "isivuno" (isivuno) ngokuvamile lihunyushwa ngokuthi "usike". Yingakho igama elithi - isivuno isici, obhekisela lokho okwenziwe anda ubude ebalulekile. Lichaza ngokunembile ngesikhathi esifanayo, eqinisweni kukhona inqubo sokudubula, njengoba ngomqondo ngokomzimba, ikhamera lens ubude ebalulekile engashintshwa, kodwa ukushintsha engela umbono.

Ngakho, Uhlaka osayizi 35 timillimetrovoy ifilimu 24x36 mm ubulokhu ihlala yereferensi, manje okuyinto ixhunywe nezitshalo isici. Ukuze Uhlaka ezinjalo kuba elilingana 1. Ekuqaleni kwenkathi, Nikon izithombe digital, ngokuhlakanipha yakhetha ukuthi kungenzeka ukukhiqiza digital SLR amakhamera ne ikhono ukuzisebenzisa ne yokukhanya ubudala, okuyinto zenziwa amashumi eminyaka futhi ngokuvamile ibize ngaphezu kuka ikhamera ngokwayo.

Nokho, ekwenziweni lo mbono sinenkinga. Dala inzwa yobude obugcwele wazibonakalisa ebiza kakhulu, futhi nje incane kakhulu ngeke kusasiza ngalutho.

Ngenxa abacwaningi inzwa usumisiwe, owawungumnyaka idayagonali nokuncane nohafu kuka uzimele 35 timillimetrovoy ifilimu. Ngakho, i-inzwa 1.5 ezinjalo - lena isilimo sakhe isici. Canon ngenhlanhla kamuva athole ikhambi elingcono ngisho. Nqampuna Isici emagumbini ayo alingane 1.6.

Ukuze ngandlela-thile ezahlukene ezivela kuye, isitshalo Isici Nikon waqala ukubiza DX, futhi yobude obugcwele inzwa FX. wekhodi okunjalo iyaqhubeka nokuba khona namuhla. Isetshenziselwa ezinye izinkampani eziningi, ngaphezu Nikon.

Abakhi amakhamera ne kwezitshalo isici, wasebenzisa lokho endaweni izinzwa wazo lehla ngesibalo esingaphezu kwengxenye. Lokhu kwabangela ukonga womshini yokukhanya enamandla futhi kuyabiza. Abakhiqizi eseqala ukuveza izinto eziningi mass amakhamera digital ziyatholakala anhlobonhlobo bezithombe.
