Ilensi entsha yeCanon macro zoom iya kukhutshwa ekupheleni kuka-2014

ICanon inamahemuhemu okuba isebenza kwiliso lokusondeza i-macro ejikeleze uphawu lwe-200mm kwaye iya kubhengezwa ukuphela kuka-2014.

Njengoko "unyaka welensi" yeCanon uqhubeka ngaphandle kokumiselwa ngokusesikweni kwayo nayiphi na iilensi, umzi-mveliso wokuhleba uyaqhubeka nokusasaza intlebendwane malunga nezicwangciso zenkampani zowama-2014.

Ngapha koko, ababukeli beshishini bafumanisa amalungelo awodwa omenzi wechiza kwiilensi ezintsha, bechaza ezinye iimveliso ezinokuthi zityhilwe kulo nyaka.

Ilensi entsha yeCanon macro zoom inentlebendwane yoluhlu lwezemidlalo olujolise kwi-200mm

ICanon EF 100mm f / 2.8L ISM USM Macro yenye yeefowuni ezimbalwa zeelensi ezinkulu zeekhamera ze-EOS. Inkampani inamahemuhemu okubhengeza imodeli yokusondeza ukulungisa oku kusilela ekupheleni kuka-2014.

Ukufunyanwa kwakutshanje kwelitye lokuguba kuqukethe i-Canon macro zoom lens entsha. Le ayisiyiyo ye-optic yokuqala kudidi lwayo ukuba ibe ngamahemuhemu, kodwa inokuba yeyokuqala ukukhutshwa kwintengiso kunye noluhlu olugxile kwi-200mm.

Imithombo ibanga ukuba imveliso ikwisigaba seprototype, ke umenzi we-EOS usayifaka kwaye uzama ukumisela ukuba zeziphi izinto zokugqibela ezinokufakwa kwiilensi.

Omnye wabo kukuthatha isigqibo sokuba okanye hayi ukongeza itekhnoloji yokuqinisa uzinzo. Ngenxa yoko kufanelekileyo, i-IS iya kuba luncedo ekuthatheni i-macro shots, ke iCanon iya kutsala umdla wabathengi ngakumbi ngokongeza le nkqubo.

Iilensi ezinkulu zeCanon ziya kubonisa ukuvuleka okuphezulu okungapheliyo

Iintetho zokuhleba ziyaqhubeka "nesiqinisekiso" sokuba i-optic iya kubonisa ukuvulwa okuphezulu okungapheliyo. Ixabiso layo alikhange livulwe, nangona kufanelekile ukuba silindele ukuba eli liqaqambe kakhulu-elinokuba lijikeleze f / 4- elinokuba luncedo kakhulu kwimifanekiso emikhulu.

Umntu ovuzayo uthethile ukuba ilensi ibonelela nge-2: 1 macro ratio, kodwa akufuneki sithathe umda we-1: 1 xa uyisebenzisa kwelona xesha lide. Njengesiqhelo, yithathe ngengqolowa yetyuwa kuba akukho bungqina bokuxhasa amabango, ke kuya kufuneka uphephe nakuphi na ukuphoxeka okukhulu.

Nokuba yeyiphi na indlela, imithombo ithe i-lens entsha ye-Canon zoom iya kukhutshwa ukuphela konyaka kwaye kushiyeke ixesha elininzi kude kube lelo xesha.

Iilensi ezimbini zoom zekhamera yeCanon APS-C DSLR enelungelo elilodwa lomenzi eJapan

I-Canon zoom lens patent yamva ichaza ii-optics ezimbini ze-EF-S, zombini ziphela nge-55mm kunye nefertile ye-f / 3.5-5.6. Nangona kunjalo, enye yazo iqala nge-18mm, ngelixa enye i-17mm.

Okwangoku, iCanon inelungelo elilodwa lomenzi wechiza ngeelensi ezimbini. Zombini ziyafana, kodwa inye kuphela eya kukhutshwa kwintengiso.

Eyokuqala yi-EF-S 18-55mm f / 3.5-5.6 IS STM lens, eya kuthi ibe yilensi yekiti ye-Canon EOS DSLRs ene-APS-C yomfanekiso woluvo ngokutshintsha isizukulwana sangoku.

Imodeli yesibini yi-EF-S 17-55mm f / 3.5-5.6 IS STM lens. Kukho umahluko we-1mm, ke kuya kuhlala kubonakala ukuba inkampani iya kuhamba ngokubanzi okanye hayi. Zonke ziya kutyhilwa ngo-2014, ke khumbula ukuba umonde yinto elungileyo.
