I-Canon ibuyela kwiiNqanaba eziphezulu ze-DSLR kunye ne-7D
I- Canon EOS 7D yikhamera ye-APS-C ehamba phambili. Eyilwe kwiikhamera eziphambili ezifana ne-Nikon D300S, idibanisa inani eliphezulu le-megapixel nge-tag price price.
Kwiinkalo ezininzi, le khamera inokudibanisa i-Canon ye-5D Mark II. Ukuba awuyidingi ikhamera yesigxina epheleleyo, uya kuba nzima ukufumana isizathu sokuthenga amaxabiso angama-5D.
Uhlaziyo luka-2015: I-Canon EOS 7D yaqala ukukhutshwa ngo-2009 kwaye oku kuhlaziywa kubhalwe ngo-2010. Ngowokugqibela kwinguqu ye-7D, khangela i-Canon EOS 7D Mark II, enee-megapixel ezingama-20.2 kunye ne-HD egcweleyo yevidiyo.

- Ihlala ikhupha kancane kwiimeko ezifani kakhulu
Uhlolo lwe-Canon EOS 7D
I-Canon ngokuqinisekileyo yayiyinkokeli yemakethi kwi-SLRs yedijithali ixesha elide, ukuvelisa zombini umthengi "isakhelo sesityalo" kunye neengcali "ezipheleleyo zeefowuni".
Emva koko, bobabini uNicon no-Sony baqala ukuvelisa iikhamera ezixhatshazayo-kwaye kwezinye iimeko zidlulile-iminikelo yabathengi beCanon. I-EOS 7D yempendulo yeCanon kubadlali bayo.
Ngama-megapixels angama-18 kunye nomzimba onamandla omnyuzi, le khamera iwa phantsi kweliqela eliphakathi labathengi abaxhamli, kubandakanye nalabo abafuna into ethile kwi- DSLR yomthengi. Ukongezelela, kufike ngetekethi exabiso elihle. Kodwa ingabe isaba isithsaba xa kuziwa kwiifomera ze-APS-C?
Inkqubo ye-AF
I-7D ineenkalo ze- AF -19. Le nto, ngokulula, enye yeendlela ezijolise ekugqibeleni ukuba ndizibone ixesha elide. Akunako kuphela ukuzenzekela ngokuzenzekelayo okanye ngokukhetha ngokukhetha ukhetho lwama-AF, kodwa ungasebenzisa iimodi ezahlukeneyo ukukunceda ukuba wenze uninzi lwenkqubo.
Ngokomzekelo, kukho inkqubo yoMmandla we-Zone, ebeka amaqela kwiindawo ezinhlanu ukukunceda ugxininise ingqwalasela yekhamera kwisabelo somfanekiso onqwenela ukujolisa. Kukho ukunyuka kwe-Spot AF kunye ne-AF, kwaye unokwenza inkqubo yekhamera ukuba igxume kwimodyulo ethile, kuxhomekeke ekuqhelweni kwayo.
Yonke into ijoliswe ekuncedeni ukuqinisekisa ukuba umfanekiso ujolise. Ngokunyanisekileyo, kuya kufuneka wenze umgudu wangempela ukuba ungabi nomfanekiso ekujoliswe kuyo!
Imodi Yomdlalo
Imodi ye-Movie kwi-Canon EOS 7D inomlinganiselo olawulayo olawulayo, ovumela ukuba ubeke ukuvula nokukhawuleza.
Kukho imodeli epheleleyo ye-HD (i-1920 x 1080 pixels) kunye nemakrofoni yangaphakathi ukurekhoda umsindo we-mono. Unokufakela i-microphone yangaphandle kwijack yezwi elipheleleyo le-stereo. Ukucubungula kwe-Dual Digic 4 ye-7D kukunceda ukuvelisa umkhiqizo wevidiyo ophezulu omangalisa ikhamera yale xabiso lemali.
I-drawback kuphela ezayo ukuba ufuna ukudubula ngesivinini esheshayo (ama-50 ozimele ngesibini) efuna isisombululo esincinane (720p). Kule sigqibo, ezinye iimizila ezinemizila zingabonakala kwimida ediagonal, kodwa oku akuyona ingxaki kwisigqibo seHD esigcwele.
Ibhalansi eMhlophe
I-Canon ayizange ixazulule imiba nge-balance balance white in the conditions of lighting conditions, kwaye i-Canon EOS 7D ayikho. Ukuba ufuna abahlophe abamhlophe ngaphakathi, ngokuqinisekileyo kuya kufuneka ukuba usebenzise isilungiselelo sokuBala iMahia eMnyama.
Ewe, ngaphandle kokuba uhlala kwimeko ye studio kwaye ufuna ukulinganisa okugqibeleleyo kumhlophe, unokuvuyela ukuvumela le sidididi. Isiphumo, nangona kunjalo, ukuba abamhlophe baya kuba ne-yellow tinge ecacileyo. Unako ukuhlawulela oku ngokuphinda uhlasele i-RAW kwaye unxibelele utshintsho lwakho kwimveliso emva kokuvelisa.
I-Flash
Inqaku elisebenzayo le-7D kukuba i-flash-pop-flash edibeneyo i-Speedl-transmitter ezinikeleyo. Oku kuthetha ukuba ikhamera iya kulawula ngaphandle kwekhamera ikhenkce, ngokusebenza njengokukhanya kwe-trigger.
Quality Image
Umgangatho womfanekiso kwi-7D ulungile kakhulu kulo lonke udidi lwe- ISO . Kwi-ISO ephantsi, umgangatho womfanekiso uhlukile kule klasi yekhamera. Into eyoyivumela ukuba le khamera iphantsi kwekhwalithi yile lenshibhile!
Ikhamera iphinda yenza kakuhle kwiimeko eziphantsi zokukhanya. Inkomfa yodwa kunye nekhwalithi yinto yokwenza ikhamera yokunyusa kwiimeko ezichaseneyo. Nangona kunjalo, le nto inokuphetshwa kakhulu kwinxalenye xa udubula kwi-RAW.
Ukuququmbela
Ikhamera ye-APS-C ye-Canon ifake i-Canon iphinda ibuyele kumdlalo. I-Canon EOS 7D ngokuqinisekileyo inamathela kuzo zonke ezinye iikhamera kwiklasi. Ndiza kuthetha nokuba ihamba nayo ngokumelene nomntakwabo omkhulu, i-5D Mark II (ngaphandle kokuba ufuna isakhelo esipheleleyo).
Inkqubo yokugxila kwe-AF yintlambo yokuyisebenzisa, kwaye umgangatho walo mfanekiso uphezulu. Ngaphezu koko, ikhwalithi yakhe yokwakha enamandla kunye nokukwazi ukuvelisa imifanekiso ephezulu kwi-RAW kunye ne-JPEG yenza ukuba ixabise imali.
Le yinye ikhamera yeCanon endiya kuyincoma ngaphandle kokungabaza.
