Le mpazamo inkulu nomthengi - ukuthembela olomeleleyo kwi amazwi kwindawo yokuthengisa umcebisi. Njengoko yaziwa, abaphathi msebenzi eziphambili - ngokwanda ukuthengisa. Kuba nabathengisi imveliso ophezulu kuthengisa namaqhinga ezahlukeneyo, ezifana njengoko kubonisiwe kwi inkcazo sixhobo sibaluleke zoom enkulu, yaye yintoni uhlobo zoom (enombala kunye digital) azibonisi, kuba ndifuna kakuhle umthengi. Ukunqanda konke oku kwaye khetha isixhobo ilungileyo Kubalulekile ukwazi kusengaphambili yonke malunga umsebenzi ukucupha kunye zoom emaXhoseni.

Yintoni zoom?

Zoom kuxhomekeke ubude. FR - ke ubude kwicandelo ukusuka embindini lens isizalo, oko kukuthi, ingongoma ekujoliswe ... Wagqiba ekubeni babhiyozele kwi ilens e iimillimitha, umzekelo, ipere 5,8-24 amanani mm: umvo lokuqala - i responce kwi ekupheleni elifutshane, kwaye inani lesibini - DF kwi ekupheleni elide. Xa sisahlula ngenani ngenani RF elide elifutshane, sifumana ixabiso yokusondeza, lingana ne ukuya ezine.

zoom yedijithali

Ngoku siyazi ukuba ukucupha kufuneka ukuqonda iintlobo zalo ezisisiseko: digital nezibonwa. Ezinye khamera bahlanganisa kwaye, kunye nezinye iintlobo.

Digital Zoom, xa kuthelekiswa ne woqondo - luhlobo eyinyani, ngokuba ngenxa ukusebenzisa kwayo yimveliso processing zingafumaneka, ngokwenene ngokomgangatho wasondela injongosenzi efotweni. Yokutshintshwa kwamanqaku kwenzeka ngokuthi esisuka ngundoqo mfanekiso yeprogram nemida de ifikelela ubungakanani kwisakhelo sokuqala.

Ukuba dijithali mkhulu, umfanekiso angandiswa kunye nokulahlekelwa encinane yomgangatho, ukuba incinane, ngoko ke ukwanda umgangatho ilahlekile nobutyobo. zigcwaliswe sele Iingceba Tiny ayikwazi ngokomgangatho ngcono, ukuze loo imifanekiso kunye ukwandisa pikseliziruyutsya ngamandla.

Kunjalo, oku kubonisa ngokucacileyo ukuba ngokusebenzisa dijithali, ungafumana umfanekiso esezantsi-umgangatho, kuba indlela processing akemi ngxi, yaye njalo ngcono. Ethelekiswa izixhobo kwiminyaka nje 7 eyadlulayo, iikhamera yangoku inkqubo yonyango nga ngokuphawulekayo ukwandisa mfanekiso, nto leyo eyenza kube ngendlela eyiyo, ukuba ndisolulela phantse kungabonakali.

Ukuba iimfuno zakho ukucupha ngokucacileyo akanelisekanga, ungakwazi noba khubaza okanye ukutshintsha izicwangciso ixabiso layo.

optical zoom

Loo zoom - le sikrini yi ngokusetyenziswa eyepiece. Ngokunciphisa ngokutsha ekujikeni, t. E. Ubude focal, le kelelo lwenziwa lo moya efotweni into. Inzuzo ephambili zoom woqondo edijithali kukuba umfanekiso kakhulu ngazo kuwo akukho lincitshiswe inter-pixel izithuba, ngoko ke umgangatho photo ayikho zathotywa.

Uluhlu ubude bamalungelo ezesini kungabonwa ngqo kwi lens. Kakade ke, xa ukhetha ikhamera , kukhethwa ukuba ixabiso elikhulu kunokwenzeka oko, kokukhona ukuba ishishini akuyomfuneko kunye optical zoom kwindawo, ngokoqobo "bexhentsa" izixhobo ngakumbi nobunzima kakhulu.

Superzoom - ilwela zoom ubuninzi

Ngelo xesha langoku, enombala 10x usondeze nga kusimangalise ngaphandle kokuba nomama oneminyaka engama-80 ubudala. Inkqubela phezu kobuso, kwaye isizukulwana yangoku sele ukonwabela ngokukhululekileyo iikhamera compact exhotyiswe 50x zoom. Oku kuhlolwa nje nje impumelelo, kodwa uvale, atsibatsibe ngaphakathi kwizizukulwana elide. Eneneni, yintoni na dijithali, xa kuthelekiswa super Optical? Kuqinisa zoom iifoto umgangatho ophezulu sele ukwenza ukhuphiswano obubonakalayo iiseti ngumsina of SLR kunye lens abaninzi abafoti yobungcali umbilo yayiqhubeka zonke Kuphendula photo. Ngokuqhelekileyo, abaninzi i "widgets" ezithile zisebenze kakhulu superzoom yokuthathwa compact indawo, kodwa ngokwemiqathango ukuhamba kunye ergonomics, ukuba ubanike isiqalo intloko.

Ngenxa yokuba kwizivumelwano ngoko ube zoom lens enamandla yale icamera ayi kufuna ukususwa rhoqo / ixhotyiswe ukuze ufumane ezona ezifanelekileyo ifoto shoot ethile ukwenzela ukuba kunqanda uthuli bangene matrix.
