Ikhamera engenazibuko yakwaSony A7R II ivezwe ngama-specs ajabulisayo

AbakwaSony ekugcineni bamemezele i-A7R II njengongena esikhundleni se-A7R, imodeli entsha eba yikhamera yokuqala yomhlaba enenzwa yesithombe esigcwele esikhanyayo emuva.

Njengokubikezela kwamahemuhemu, U-Sony wethule ikhamera entsha engenazibuko ephezulu ye-FE-mount ngasekupheleni kwekota yesibili yonyaka wezi-2015. Kodwa-ke, isigayo sokuhleba sithole eminye imininingwane eminingi engalungile, njengoba i-A7R II imele intuthuko enkulu kunaleyo eyandulelayo, i-A7R.

Intuthuko ephambili inzwa yesithombe. ISony A7R II entsha iza igcwele inzwa yokuqala egcwele ekhanyiswe emuva emhlabeni eletha ukuzwela okuphezulu, ukuzinza kwesithombe esakhelwe ngaphakathi kwe-5-axis, nobunye ubuchwepheshe obuningi obuwusizo.

ISony A7R II iba semthethweni ngenzwa yohlaka oluphelele lokuqala emhlabeni

Ukukhanya kwangemuva kungene ezindlebeni zesithombe eminyakeni edlule, kepha lolu hlelo lukhona ngamayunithi amancane. AbakwaSony bathatha izinto baye ezingeni elilandelayo ngenzwa entsha sha engu-42.4-megapixel egcwele uhlaka ngaphandle kwesihlungi se-anti-aliasing, esiphenduke inzwa yokuqala engu-35mm ekhanyiswe emuva emhlabeni.

Inzwa entsha ye-BSI Exmor R inikeza cishe ama-megapixel angama-42.4, kuyilapho inzwa eku-A7R inikeze cishe ama-megapixel angama-36.4. Ngenkathi isinqumo esiphakeme sihlanganisa, ukufakwa kobuchwepheshe be-BSI kubeka ukuzwela okuphezulu kwe-ISO okungu-102,400 ekutholakaleni kwabasebenzisi, izitobhi ezimbili ezingaphezu kwe-A7R.

Inzwa ye-42.4-megapixel ifaka amaphuzu we-5-axis IBIS namaphoyinti e-PDAF endiza eyi-399

Inzwa entsha yakwaSony inamaqhinga amaningi phezulu komkhono wayo. Ifaka ubuchwepheshe be-5-axis image stabilization technology etholakala ku-A7 II FE-mount mirrorless camera. I-5-axis IBIS izohlinzeka ngokuma okungu-4.5 kokuqina ukuze kusizakale abasebenzisi abaphansi.

Inzwa ye-BSI engu-42.4-megapixel iphinde isebenzise amaphoyinti angama-399 okugxilwe kuwo endizeni ye-Phase Detection Autofocus ukuze inikeze ukumbozwa okubanzi kakhulu kwe-autofocus okutholakala kumakhamera anezinzwa ezinohlaka oluphelele. Amaphuzu we-PDAF angama-399 ahlanganiswe ngamaphuzu angama-25 okuThola ukuBona kwe-AF futhi asebenza ngokubambisana ukuhlinzeka ngejubane le-AF elingu-40% kunesistimu ye-AF ku-A7R.

Ikhamera engenazibuko yakwaSony A7R II inikwe amandla yi-BIONZ X processor processor futhi izokwazi ukuthwebula ifike kuma-5fps kumodi yokudubula eqhubekayo ngokulandela i-AF kuvuliwe.

Ikhamera entsha engenazibuko ye-A7R II inikeza ukuqoshwa kwevidiyo okungu-4K

Ukuze wenze lokhu kube ngcono kakhulu, i-A7R II iyakwazi ukuqopha amavidiyo we-4K. Ikhamera izorekhoda amavidiyo angama-3840 x 2160-pixel aze afike ku-30fps kumodi ye-MPEG4 / AVCHD noma afike kuma-24fps kusetshenziswa i-XAVC S codec.

AbakwaSony baqinisekisile ukuthi ikhamera ingabamba amavidiyo angama-4K ngemodi yohlaka oluphelele noma ngemodi yeSuper 35mm. Kwimodi yokugcina, ikhamera ithatha imininingwane kusuka kumaphikseli angaphezulu kwe-1.8x kune-4K isebenzisa ukufundwa kwamaphikseli okugcwele nokusampula ngokweqile ukunciphisa ama-moiré nokunye ukukhubazeka.

Abadwebi bamavidiyo bazokuthokozela ukuzwa ukuthi iSony A7R II isekela i-S-Log2 Gamma, S-Gamut, Iphrofayili Yesithombe, i-timecode, nokuhlanzwa kwe-HDMI phakathi kwabanye.

Ekugcineni, abalandeli bokuhamba kancane bangaqopha amavidiyo angama-720p ngesilinganiso esiphakeme sama-120fps.

Ikhamera entsha yakwaSony isekela i-autofocus ngama-lens we-A-mount nama-third-party

Ukubuyela kusistimu ye-autofocus, iSony A7R II izokwazi ukwenza i-autofocus lapho kufakwa amalensi e-A-mount noma ama-third-party. Inkampani ikuqinisekisile ukuthi lokhu kungenzeka ngenxa yohlelo lwe-Phase Detection AF.

Yize amaphoyinti e-PDAF emboza ngaphansi kwengxenye yesizweli, abathwebuli bezithombe basathola ukumbozwa kwendawo engama-67% kuzo zonke izinkomba. Amanye amasistimu angenazibuko ahlinzeka ngokumbozwa okuningi, kepha izinzwa ezintsha zakwaSony zigxila kuzinzwa ezitholakala kumakhamera weDSLR.

Kunoma ikuphi, unganamathisela amalensi we-Canon EF-mount ku-A7R II usebenzisa i-adaptha ye-elekthronikhi evela kwaMetabones futhi ikhamera izokwazi ukugxila. Ngaphezu kwalokho, izokwenza lokho ngokushesha futhi izosekela i-AF Tracking.

Njengoba kushiwo ngenhla, i-FE-mount mirrorless camera nayo izogxila lapho kunamathiselwa ama-lens we-A-mount nge-adaptha ye-LA-E3. AbakwaSony baqinisekisile ukuthi amalensi ayisishiyagalombili amasha we-FE-mount eza ekuqaleni kuka-2016, kepha uma ungakwazi ukulinda, ungabamba i-adaptha bese ukhetha ezinqwaba zama-A-mount namalensi enkampani yangaphandle.

I-shutter ethule ngokugcwele ye-elekthronikhi nekhethini lokuqala le-shutter elenzelwa ku-A7R II

Enye i-plus uma iqhathaniswa neyandulelayo imelwe ubuchwepheshe be-shutter. AbakwaSony bethule i-shutter entsha sha ku-A7R II eqinisekisiwe ukuthi izosebenza kuze kube yimishini yokucindezela engafika ku-500,000.

I-shutter ifaka i-shutter shutter yokuqala ye-elekthronikhi ezosusa ukudlidlizela ukuze abathwebuli bezithombe bangabe besakhala ngokudutshulwa kubude be-telephoto.

Ngaphezu kwalokho, imodi yokuvala ngokugcwele i-elektroniki iyatholakala, nayo. Ithule ngokuphelele futhi izongena kahle ezindaweni lapho abasebenzisi kumele bahlale bengabonakali ngangokunokwenzeka.

Ubuchwepheshe be-WiFi ne-NFC buzovumela abasebenzisi ukuthi balawule kude i-Sony A7R II

Okusele kohlu lwama-specs akwaSony A7R II kufaka phakathi isibani sokusiza se-autofocus, ukwesekwa kweRAW, isikrini esilinganisa i-LCD esine-3-intshi, kanye nesibukeli sokubuka se-OLED esakhelwe ngaphakathi nesixazululo samachashazi angu-2.4-million.

Ububanzi obuzwelayo be-ISO buphakathi kuka-50 no-102,400, kanti isivinini se-shutter simi phakathi kuka-1 / 8000s namasekhondi angu-30. Izilawuli ezenziwa ngesandla zikhona kwikhamera kanye nesihlangu esishisayo, kepha ayikho i-flash eyakhelwe ngaphakathi.

Njengoba bekulindelwe, ukufaka esikhundleni kwe-A7R kufaka i-WiFi ehlanganisiwe ne-NFC. Lawa mathuluzi wokuxhuma azovumela abasebenzisi ukuthi bathumele amafayela ku-smartphone noma kuthebhulethi futhi bakwazi ukulawula ikhamera ngomakhalekhukhwini.

Ikhamera engenazibuko yesimo sezulu yakwaSony A7R II ezokhishwa kulo Agasti

ISony A7RII iyikhamera evalwe sezulu ekwazi ukumelana nothuli, umswakama namazinga okushisa aphansi. Idivayisi ilinganiselwa ku-127 x 96 x 60mm / 5 x 3.78 x 2.36 amayintshi, ngenkathi isisindo esingu-625 gram / 22.05 ounces namabhethri afakiwe.

Ikhamera engenazibuko inikela ngempilo yebhethri efinyelela kuma-290 shots ngokushaja okukodwa namachweba ambalwa, njenge-USB 2.0, HDMI, microphone, nehedfoni.

Usuku lokukhishwa kwe-A7R II kuhlelwe ukuthi lube ngo-Agasti 2015. Ikhamera izotholakala ngentengo engu- $ 3,200, cishe ebiza u- $ 900 ebiza kakhulu kunangaphambili.

I-Amazon isivele ibhale i-A7R II kuwebhusayithi yayo futhi izotholakalela uku-odwa ngaphambili kungekudala.
