I-Canon Ibuyisa Eziphezulu Ze-DSLR Nge-7D
I- Canon EOS 7D yikhamera ye-APS-C ehamba phambili yomkhiqizi. Iklanyelwe kumakhamera aphikisanayo njenge-Nikon D300S, ihlanganisa inani eliphezulu le-megapixel ngetekisi lentengo elungile.
Ngezici eziningi, leli khamera lingakwazi ngisho nokuphikisana no-Canon 5D Mark II. Uma ungadingi ikhamera yefrimu ephelele, uzobe ucindezelwe kanzima ukuthola isizathu sokuthenga ama-5D abizayo.
Isibuyekezo sika-2015: I-Canon EOS 7D yaqala ukukhishwa ngo-2009 futhi lokhu kubuyekezwa kubhalwe ngo-2010. Kuyinto ikhamera elihle kakhulu futhi lihlala lithenga elimangalisayo kumakethe asetshenzisiwe. Ngenguqulo yakamuva ye-7D, bheka i-Canon EOS 7D Mark II, enama-megapixel angu-20.2 nekhono eligcwele levidiyo ye-HD egcwele.
Izinzuzo
Cishe kakhulu kakhulu ongakusho, kodwa nansi ambalwa:
- Ama-megapixel angu-18
- Isistimu ye-19 ye-AF
- Amafreyimu angu-8 ngomzuzwana oqhubekayo wokudubula
- Ukusebenza okuphansi okuhle kakhulu
- Ukuphila okuhle kwebhethri
- Cishe zonke izinkinobho nokulawula kungenziwa ngezifiso ngokusho okuthandayo
I-Cons
- Ibhalansi emhlophe engenakwenzeka ezimweni zokukhanyisa ezenzakalelayo
- Kuvame ukuxoshwa kancane ezimweni eziphambene kakhulu
Ukubuyekezwa kwe-Canon EOS 7D
I-Canon ngokuqinisekile yayiwumholi wemakethe ku-SLRs yedijithali isikhathi eside, okhiqiza kokubili umthengi "uhlaka lwezitshalo" kanye namakhamera ochwepheshe "ohlakalekile".
Khona-ke, kokubili u-Nikon no-Sony baqala ukukhiqiza amakhamera aphikisanayo-futhi kwezinye izimo badlula-iminikelo yabathengi. I-EOS 7D impendulo yeCanon kulabo abathintekayo.
Ngama-megapixel angu-18 nomzimba onzima we-magnesium, le ikhamera iyawela eqenjini eliphakathi kwamakhasimende we-prosumer, kuhlanganise nalabo abafuna okuthile okuvela kumthengi we- DSLR . Ngaphezu kwalokho, kuhambisana nomthamo wamanani ahle kakhulu. Kodwa ingabe iba umqhele uma kuziwa kumakhamera we-APS-C?
I-AF System
I-7D iqukethe isimiso se- AF -19. Lokhu, okulula, enye yezinhlelo ezigxile ekugxileni engizange ngizibone isikhathi eside. Akukona nje kuphela ongakhetha ngokuzenzakalela noma ngokukhetha amaphoyinti e-AF, kodwa ungasebenzisa izindlela ezihlukene ukukusiza ukuba wenze uhlelo oluhle kakhulu.
Isibonelo, kunesimiso se-Zone AF, esihlanganisa amaphuzu zibe izingxenye ezinhlanu ukukusiza ukuba ugxile ukunakekelwa kwekhamera engxenyeni yesithombe ofuna ukugxila. Kukhona ukuthuthukiswa kwe-Spot AF ne-AF, futhi ungahlela ikhamera ukuze igxume kwimodi ethile, kuye ngokuthi i-orientation yayo.
Konke kuhloswe ekusizeni ukuqinisekisa ukuthi isithombe sigxile. Ngokwethembeka, kuzodingeka wenze umzamo wangempela ukuze ungagcini isithombe!
Imodi ye-Movie
Imodi ye-Movie ku-Canon EOS 7D inezilawuli ezigcwele zombhalo, okuvumela ukuthi uhlele isivinini sokuvula nokuvala.
Kukhona imodi egcwele ye-HD (amaphikseli angu-1920 x 1080) nomakrofoni wangaphakathi ukurekhoda umsindo we-mono. Ungakwazi ukunamathisela imakrofoni yangaphandle ku-jack for umsindo ogcwele we-stereo. Ukucubungula kwe-Dual Digic 4 ye-7D kusiza ukukhiqiza ukukhishwa kwevidiyo ephezulu okumangalisa ikhamera yobubanzi bamanani.
Impendulo kuphela efika uma ufuna ukudubula ngesivinini esisheshayo (amafrimu angu-50 ngomzuzwana) odinga ukuxazulula okuphansi (720p). Kule ngqungquthela, imigqa eminye egijimayo ingabonakala emaphethelweni e-diagonal, kodwa lokhu akuyona inkinga ngokugcwele kwe-HD.
Ukulinganisa Okumhlophe
I-Canon nje ayizange ixazulule izinkinga ngokulinganisela okumhlophe okuzenzakalelayo ezimweni zokukhanyisa okufakelwayo, futhi i-Canon EOS 7D ayilutho. Uma ufuna abamhlophe abamhlophe bengena endlini, cishe kuzodingeka ukuthi usebenzise isilungiselelo se-Custom White Balance .
Yebo, ngaphandle uma usesimweni se-studio futhi udinga ibhalansi elimhlophe elihle, ungase ujabule ukuvumela lokhu kulayishwe. Nokho, umphumela wukuthi abamhlophe bazoba ne-tinge ephuzi ngokucacile. Ungakwazi ukubuyisela lokhu ngokuphonsela i-RAW bese ubhalela izinguquko zakho ekuthumeni kokuthunyelwe.
Flash
Isici esiwusizo se-7D ukuthi i-flash integrated pop-up nayo i-transmitter ezinikezele. Lokhu kusho ukuthi ikhamera izolawula ukukhipha ikhamera ikhamera, ngokusebenza njengokukhanya kwe-trigger.
Ikhwalithi yesithombe
Ikhwalithi yesithombe ku-7D ihle kakhulu kuwo wonke ububanzi be- ISO . E-ISO ephansi, ikhwalithi yesithombe ayifanele kule klasi yekhamera. Into kuphela ezovumela le ikhamera phansi kwikhwalithi yileli eshibhile!
Ikhamera iphinde isebenze kahle ezimweni eziphansi zokukhanya. Ukuphela kwenkinga ngekhwalithi ukuthambekela kwekhamera yokugxila kakhulu ezimweni eziphambene kakhulu. Nokho, ngisho lokhu kungagwenywa kakhulu uma udubula ku-RAW.
Ekuphetheni
Ikhamera ye-APS-C ye-Canon ye-flag ye-Canon iphinde imise i-Canon emuva kumdlalo. I-Canon EOS 7D ngokuqinisekile iyithatha ngokumelene nazo zonke ezinye amakhamera ekilasini layo. Ngingasho ngisho ukuthi iphikisana nomfowabo omkhulu, i-5D Mark II (ngaphandle uma ufuna isakhiwo esigcwele).
I-AF igxile ohlelweni kuyinjabulo yokusebenzisa, futhi izinga layo lesithombe lihle kakhulu. Ngaphezu kwalokho, ikhwalithi yakhe yokwakha enezintambo kanye nekhono lokukhiqiza izithombe eziphakeme kakhulu ku-RAW naku-JPEG yenza kube kuhle ngemali.
Lena enye ikhamera ye Canon engingayincoma ngaphandle kokungabaza.
