I-Sony A7R IV: ukubuka konke okusheshayo kwefreyimu ephelele

Abasebenzisi bezokuxhumana nomphakathi sebevele babiza iBy Corporation Corporation entsha nge-61 megapixel ibhomu. Ngemuva kwakho konke, le yikhamera yokuqala engenazimele egcwele i-matrix emakethe yomhlaba. I-Sony A7R IV iphambi kakhulu kwabaqhudelana bayo ekucacisweni kobuchwepheshe kanye nokusebenza.

 

 

AbakwaCanon noNikon nabo kulindeleke ukuthi balethe izisombululo zabo emakethe. Ochwepheshe baphawula ukuthi izimbangi azikaze zibe nemikhiqizo emisha ethokozisayo isikhathi eside. Ngenxa yalokho, uSony waba owokuqala "ukudubula". Futhi kahle kakhulu. Ngemuva kokwenza isethulo sekhamera nokwabelana ngezimpawu zobuchwepheshe, abamele inkampani bayimemezele umnqamulajuqu wokuthengiswa kwemishini nentengo yokuqala. Okusha kuzothengiswa ngoSepthemba 2019 walo nyaka, intengo yokuqala ngamadola we-3500 US.

 

I-Sony A7R IV: ukubuka konke

• UMax Usayizi Wezithombe: 9504 x 6,336
• Amamodi wokulinganisa: I-Multi-Segment, Isisindo Esilinganiselwe, Isikhala, Okumaphakathi, Okugqamile
• Ividiyo: 4K UHD e-30p, 24p
• Isibuko sokubuka: amaphuzu we-EVF, 5,76 m
• Ikhadi Lememori: I-2x SD / SDHC / SDXC (UHS II)
• I-LCD: Isikrini sokuthinta i-3 intshi touch, amachashazi e-1,44 m

• Isisindo: 655 g (izindlu kuphela, nebhethri nekhadi le-SD)

 

Ngokuya ngama-specs, i-Hybrid AF ibukeka iphelele. Imodi yokuqoshwa kwevidiyo iyadida kakhulu. Esinqumweni se-4K, isilinganiso sohlaka silinganiselwe kakhulu - 30p no-24p. Kuyadabukisa ukuthi uSony wenze iphutha elinjalo. Ngemuva kwakho konke, amakhamera amamodeli amadala avela izimbangi angakwazi ukudubula ividiyo ngemvamisa ka-60 / 50r.

 

 

Kodwa ukulandelela i-autofocus kanye namafreyimu we-10 ngomzuzwana lapho kuthatha izithombe kuyinkomba enhle kakhulu. Ochwepheshe bazokwazisa. Futhi - ukuthengiswa kwensiza. Abamele inkampani bathi iMark III ayimi eduze kweSony A7R IV.

 

 

Okusha kunemodi yemodi eminingi yokushintsha kwe-pixel. Ngokuhlanganisa izithombe ze-4 nedatha ephelele yombala noma izithombe ze-16 ne-pixel offset, ungakha isithombe se-240-megapixel.

 

 

ISony A7R IV isithombesombhalo we-elekthronikhi, uma siqhathanisa nesandulelayo, sinombukiso we-OLED ngezigidi zamachashazi angu-5,76 intshi. Amahemuhemu aqukethe ukuthi uSony "webe" isitholi esibukwayo esivela kuPanasonic. Okungenani kumamodeli e-S1 ne-S1R, isibukeli esifanayo. Abasebenzisi abanezandla eziqhaqhazelayo, ukuzinza kwe-5-axis kunikezwa ngesikhathi sokudubula.

 

Uhlobo olubuyekeziwe lweSony A7R III

Njengomanduleli wayo, i-Sony A7R III, ikhamera icompact kakhulu futhi ilula. Ochwepheshe bezobuchwepheshe basebenze kuma-ergonomics aleli cala. Okumangalisayo kwenze isibambo sajula. Manje ukubamba ucingo ngesandla esisodwa kulula kakhulu, noma ilensi enkulu.

 

 

Bangeze nokukhiya esikalini sesinxephezelo sokuvezwa, lapho umthwebuli wezithombe wakwaSony A7R III wayehlala engqongqoza ngomunwe. Kuthuthukisiwe izinkinobho kanye nohlu lwenjabulo - umuzwa omnandi kakhulu lapho ucindezelwa. Kujabuliswe ngokuvikelwa komzimba wekhamera othulini nomswakama.

 

 

U-Sony ulahle imakrofoni yendabuko. Manje ikhamera ye-Sony A7R IV ine-converter yayo ye-analog-to-digital. Lokhu kuhlanganiswe ngesibindi ngezindaba. Ngaphambi kokufaka isignali yomsindo ibe yidijithali, inqubo iyakwazi ukususa umsindo, ifake imiphumela futhi yenze ukucubungula ngezilungiselelo zomsebenzisi.

 

 

Okunye ukufakwa kufakwe emaphutheni ngevidiyo yokudubula ngefomethi ye-4. Akukho sihleli se-RAW kukhamera. Ukucutshungulwa kwezithombe, kufanele udlulise izithombe kwikhompyutha. Futhi, kuzilungiselelo, umsebenzisi ngeke azitholele ukusetha kwezithombe zefomethi ye-RAW uqobo. Isibonelo, sinciphisa ukulungiswa kwesithombe esingacindezelwanga. Ngenhlanhla, imakethe ye-flash drive isilungele ukunikeza ikhadi elikhulu.
