Uyini zoom ikhamera? Khetha best Zoom

Ukukhetha nokuthenga ikhamera - kuba nzima futhi enesibopho: hhayi kuphela ukuthi kubalulekile ukuba acabangele yonke imisebenzi oyifunayo futhi idivayisi izici, ngakho futhi kudingeke ukuba uthole leli thuluzi ngendlela efanele lebanga lentengo. Iphutha elikhulu kakhulu umthengi - ukuthembela ngokungathandabuzi emazwini consultant yokuthengisa endaweni. Njengoba yaziwa, main umsebenzi abaphathi - okwandayo yokuthengisa. Ukuze uthole abakhangisi ezinhle umkhiqizo yizikhangiso ku namasu ehlukene, njenge kukhonjisiwe incazelo ithuluzi okukhulu ukubaluleka zoom, futhi hlobo luni zoom (optical futhi digital) ayibonisi, enethemba lokuthi ukuhluleka umthengi. Ukuze ugweme konke lokhu bese ukhetha ithuluzi engcono kuwufanele ukwazi konke kusengaphambili mayelana umsebenzi zoom zoom izinhlobo.

Kuyini zoom?

Sondeza (zoom) - lena ekhethekile ipharamitha photodevices lens elikuvumela ukusondeza, bese kukhula izinto ukususwa. Nayo ungakwazi ukudubula kusukela inkanyezi ibanga, ukusondeza futhi ukuthatha izithombe ngisho izimbali ewindini phansi 9th, nakuba ukuhlolwa eziphathelene nezempi futhi indiza projectiles kodwa singalimali ngokwengqondo nangokomzimba.

Sondeza incike ubude ebalulekile. FR - ubude ingxenye kusukela phakathi lens matrix, okungukuthi, kwaze kwaba seqophelweni focus ... Wanquma ukugubha kwi lens ngamamilimitha, isibonelo, i-pair of 5,8-24 amadijithi mm: idijithi yokuqala - a FR ku ukuphela esifushane, kanti inombolo yesibili - DF ku ukuphela eside. Uma thina uhlukanise inombolo ngenani RF eside esifushane, sithola ukubaluleka zoom, ilingana ezine.

i-zoom yedijithali

Manje njengoba siyazi ukuthi zoom kufanele uqonde izinhlobo zalo eziyisisekelo: digital futhi optical. Ezinye amakhamera sihlanganise nokuthi, kanye nezinye izinhlobo.

Digital Zoom, uma iqhathaniswa optical - uhlobo eqanjiwe, ngoba ngokusebenzisa ukusebenzisa kwayo umkhiqizo we processing digital ingatholakala, hhayi ngempela qualitatively wasondela into esesithombeni. Ukulinganisa kwenzeka esisuka ngumgogodla ezikhungweni zomsebenzi isithombe hlelo njengoba umkhawulo kufika kusayizi wasekuqaleni uzimele.

Uma i-zoom yedijithali mkhulu, isithombe kungenziwa lenyuke nge ukulahlekelwa kancane izinga, uma incane ke ukwanda izinga kulahleka irretrievably. Kakade egcwele Fragments Tiny ayikwazi qualitatively ngcono, ukuze lezo zithombe nge okwandisa pikseliziruyutsya kakhulu.

Noma kunjalo, libonisa ngokucacile ukuthi ngokusebenzisa i-zoom yedijithali, ungathola isithombe yekhwalithi ephansi, ukuze kusebenziswe digital indlela akusho yima, njalo ngcono. Uma kuqhathaniswa namadivayisi iminyaka 7 nje edlule, amakhamera samanje uhlelo lokwelapha ungakwazi ukwandisa isithombe, okwenza kube omuhle kangaka, ukuthi esisuka cishe kungabonakali.

Uma izidingo zakho lokusondeza ngokucacile unganelisekile, ungahlala noma vimbela noma ukushintsha izilungiselelo ngokujulile ukubaluleka kwaso.

zoom optical

a zoom okunjalo - lokhu kokukhulisa by ukusetshenziswa eyepiece. Ngokunciphisa engela ukubuyekeza, t. E. ubude ebalulekile, le isilinganiselo wenziwa ku into isithombe. Inzuzo enkulu lokusondeza optical ukuze oludijithali yokuthi isithombe lunganwetshwa it is hhayi encishisiwe kokunye-pixel Isikhala, ngakho izinga sithombe phansi.

Ububanzi ubude ebalulekile kungabonwa ngqo lens. Yiqiniso, lapho ekhetha ikhamera , okungcono ukubaluleka elikhulu kunawo kungenzeka ke, kulapho ukuthi umkhakha akudingekile ne-zoom optical indawo, ngokwezwi nezwi okusho "wokushaya" amathuluzi zichwephesha nakakhulu.

Superzoom - Champions lokusondeza kaningi

Ngaleso sikhathi samanje, optical 10x zoom ungakwazi kusimangaze ngaphandle ukuthi ugogo oneminyaka engu-80 ubudala. Inqubekela ebusweni, kanye nesizukulwane samanje isivele ngokukhululekile ujabulele amakhamera compact ifakwe 50x zoom. It is esikalini hhayi njengesixuku nje intuthuko, kodwa njengoba eqa, ngena izizukulwane eside. Empeleni, yini i-zoom yedijithali, uma kuqhathaniswa nabangu-super Optical? Umtselela wesikhatsi ne lokusondeza eliphakeme quality izithombe kakade ukwenza mncintiswano eziphathekayo amasethi nzima ka SLR kanye lens ezingenakubalwa bezithombe professional umjuluko yadonsa zonke amahlumela isithombe. Ngokwemvelo, abantu abaningi bakule "amawijethi" ecacile kakhulu sokusebenza enezithombe superzoom compact alithathi isikhundla, kodwa ngokuya ukuhamba kanye Ergonomics, babanike ube nesiqalo esihle.

Ngenxa yokuthi umtselela wesikhatsi nokunye abe zoom lens enamandla le khamera akudingi ukususwa njalo / ifakwe ukuze uthole efaneleka kakhulu ethile ukuthatha isithombe ukuze ivimbele uthuli angangeni-matrix.

Sondeza futhi ekhona e-video. Samuntu eziphambili kakhulu Kulokhu kuyoba superzoom Ukusondeza mathupha. Nokho khona idivayisi umsebenzi ofanayo manje akuyona entsha, - - Ngisho naphezu kweqiniso lokuthi ividiyo ikhamera zoom lokhu ibhonasi abalulekile.

Ngakho, kungcono kakhulu ukunquma ukuthi ukhethe idivayisi nge zoom optical noma superzoom compact. Usuvele uyakwazi lokho zoom yedijithali futhi ukuthi lokhu kwanda izinga isithombe. Sondeza akufanele kube isizathu esiyinhloko ukuthenga umshini, kungcono uthenge ikhamera ezinhle, ukuhlinzeka ikhono ukushintsha yokukhanya. Kulokhu, uma isifiso noma isidingo esiphuthumayo ukuba zoom vysokokratny ekugcineni ilawula konke ukucabanga kwakho, ungahlala ukuthenga lens afanele.
