Hōʻike ʻia ʻo Sony A7R II kāmela aniani ʻole me nā kikoʻī hoihoi

Ua hoʻolaha hope loa ʻo Sony i ka A7R II ma ke ʻano he pani ma ka A7R, ke k modelkohu hou e lilo ana i pahu paʻi kiʻi mua loa o ka honua me ke kiʻina kiʻi piha piha i hoʻomālamalama ʻia.

E like me ka wili a ka wili, Hoʻolauna ʻo Sony kahi pahu paʻi aniani hou ʻole FE-mauna kiʻekiʻe loa e ka hopena o ka hapaha ʻelua o 2015. Eia nō naʻe, ua hewa ka mīkini wili hine i nā kikoʻī ʻē aʻe, ʻoiai ʻo A7R II kahi hoʻomaikaʻi nui aʻe ma mua o kāna mea i hele mua, ka A7R.

ʻO ka holomua mua ka mea ʻike kiʻi. Hoʻokomo ʻia ka Sony A7R II hou me ka sensor mua piha i hoʻomālamalama ʻia i hope i ka honua e hāʻawi ana i kahi ʻike kiʻekiʻe, kūkulu ʻia i kiʻi 5-axis kiʻi i kūkulu ʻia, a me nā ʻenehana pono ʻē aʻe.

Ua lilo ʻo Sony A7R II i kūlana kūhelu me ka mea ʻālamu piha piha piha o ka honua i hope

Ua hele a mālamalama ʻo Backside i nā kiʻi kiʻi i nā makahiki i hala aku nei, akā aia kēia ʻōnaehana i nā anakuhi liʻiliʻi. Ke lawe nei ʻo Sony i nā mea i ka pae aʻe me kahi mea hoʻopihapiha piha piha 42.4-megapixel me ka ʻole o kahi kānana anti-aliasing, a lilo ia i mea ʻike ʻia no ka 35mm mua o ka honua.

Hāʻawi ka mea ʻike BSI Exmor R hou ma kahi o 42.4 megapixels, ʻoiai ke sensor i ka A7R i hāʻawi ʻia ma kahi o 36.4 megapixels. ʻOiai he mea hoʻohui ka hoʻonā kiʻekiʻe, ʻo ka hoʻohui o ka ʻenehana BSI ke kau nei i ka ISO ISO ʻoi loa o 102,400 ma ka hoʻolilo ʻana o nā mea hoʻohana, ʻelua mau mea i kū ma mua o ka A7R.

42.4-megapixel mīkiniʻimi hiʻona 5-axis IBIS a me 399 kiko kikowaena mokulele PDAF

ʻO kā Sony mea ʻike hou he nui nā hoʻopunipuni i kona lima. Hōʻike ia i ka ʻenehana stabilization kiʻi 5-axis i loaʻa i ka A7 II FE-mauna aniani pahupaʻi ʻole. E hāʻawi ka 5-axis IBIS i nā kū he 4.5 o ka hoʻokūpaʻa ʻana i mea e kōkua ai i nā mea hoʻohana i nā ʻano kukui haʻahaʻa.

Hoʻohana pū kekahi me ka 42.4-megapixel BSI sensor 399 kiko kiko-kiko Phase Detection Autofocus i mea e hāʻawi ai i ka uhi autofocus ākea i loaʻa i nā kāmela me nā mea ʻike piha. Hoʻopili ʻia nā helu 399 PDAF e nā helu 25 Contrast Detection AF a ke hana pū nei lākou e hāʻawi i 40% wikiwiki AF ma mua o ka ʻōnaehana AF i ka A7R.

Hoʻohana ʻia ka kālele aniani ʻo Sony A7R II e kahi kiʻi kiʻi kiʻi BIONZ X a hiki iā ia ke kiʻi i 5fps i ke ʻano pana mau me ka huli AF i huli ʻia.

Hāʻawi ke kāmela aniani hou ʻo A7R II i ka hoʻopaʻa wikiō wikiō 4K

I mea e hoʻomaikaʻi ai i kēia, hiki i ka A7R II ke hoʻopaʻa i nā wikiō 4K. E hoʻopaʻa ka pahu paʻi kiʻi i nā wikiō 3840 x 2160-pixel a i 30fps i ka mode MPEG4 / AVCHD a i ʻole 24fps e hoʻohana ana i ka codec XAVC S.

Ua hōʻoia ʻo Sony e hiki i ke kāmela ke kiʻi i nā wikiō 4K ma ke ʻano piha a i ʻole ke ʻano Super 35mm. I ke ʻano hope, kiʻi ka pahu paʻi kiʻi i ka ʻike mai 1.8x mau pikela aʻe ma mua o 4K me ka hoʻohana ʻana i ka heluhelu piha ʻana i ka pixel a me ka hoʻonui ʻana e hoʻoliʻiliʻi i ka moiré a me nā kīnā ʻē aʻe.

E hauʻoli ka poʻe videographers i ka lohe ʻana ua kākoʻo ʻo Sony A7R II iā S-Log2 Gamma, S-Gamut, Profile Profile, timecode, a me nā huahana HDMI maʻemaʻe i waena o nā poʻe ʻē aʻe.

ʻO ka mea hope loa, hiki i nā mea pā mālie ke hoʻopaʻa i nā wikiō 720p ma ka palena palena palena palena he 120fps.

Kākoʻo kā kāmela kiʻi hou a Sony i ke autofocus me nā aniani A-mount a me nā ʻaoʻao ʻekolu

Ke hoʻi nei i ka ʻōnaehana autofocus, hiki i ka Sony A7R II ke autofocus ke hoʻopili ʻia nā aniani A-mount a i ʻole nā ​​ʻaoʻao ʻekolu. Ua hoʻokūpaʻa ka hui e hiki i kēia ke mahalo i ka ʻōnaehana ʻike Phase Detection.

ʻOiai ʻo ka uhi ʻana o nā kiko PDAF ma mua o ka hapalua o ka mīkini paʻi, ke kiʻi nei nā mea paʻi kiʻi ma kahi o 67% wahi o ka autofocus ma nā ʻaoʻao āpau. Ke hāʻawi nei nā ʻōnaehana aniani ʻē aʻe i ka nui o ka uhi ʻana, akā ʻo kā Sony ʻōnaehana hou kiʻekiʻe e nānā i nā mea i loaʻa i nā kāmela DSLR.

Ma kēlā me kēia ala, hiki iā ʻoe ke hoʻopili i nā aniani Canon EF-mount ma luna o ka A7R II me ka hoʻohana ʻana i ka adapter uila mai Metabones a hiki i ka pahu paʻi kiʻi ke autofocus. Eia kekahi, e hana wikiwiki ia a e kākoʻo iā AF Tracking.

E like me ka mea i ʻōlelo ʻia ma luna, e kālele pū ʻia ke kāmela aniani FE-mauna i ka hoʻopili ʻana i nā aniani A-mount ma o ka LA-E3 adapter. Ua hōʻoia ʻo Sony e hiki mai ana nā ʻewalu FE-mount hou ʻewalu i ka hoʻomaka mua o 2016, akā inā ʻaʻole hiki iā ʻoe ke kali, a laila hiki iā ʻoe ke lālau i kahi adapter a koho i nā aniani he A-mount a me nā ʻaoʻao ʻekolu.

ʻO ka pale uila uila piha a me ka pale pale uila mua i loaʻa i ka A7R II

Hoʻohālikelike ʻia kahi hua hoʻohui ʻē aʻe ke hoʻohālikelike ʻia i kona mua e ka ʻenehana shutter. Ua hoʻolauna ʻo Sony i kahi shutter hou loa i ka A7R II i hōʻoia ʻia e hana a hiki i nā kaomi 500,000.

Hōʻike ka pale i kahi pale pale uila uila mua e wehe ai i ka haʻalulu i mea e kaniʻuhū hou ʻole ai nā mea paʻi kiʻi i nā lōʻihi o ke kelepona.

Eia kekahi, loaʻa kahi mode shutter uila piha. Hāmau loa ia a e mākaukau ia i nā wahi kahi e noho mau ai nā mea hoʻohana e like me ka hiki.

E ʻae nā ʻenehana WiFi a me NFC i nā mea hoʻohana e kāohi mamao i ka Sony A7R II

ʻO ke koena o ka papa helu kikoʻī ʻo Sony A7R II e hoʻopili ana i kahi kukui kōkua autofocus, kākoʻo RAW, ke kiki ʻana i ka LCD LCD he 3 ʻīniha, a me kahi viewfinder uila OLED i kūkulu ʻia me kahi hoʻonā 2.4-miliona-kiko.

Loaʻa ka laulā ISO ākea ma waena o 50 a me 102,400, ʻoiai ke kū nei ka wikiwiki ma waena o 1 / 8000s a me 30 kekona. Aia nā kaohi lima ma ke kāmera a me kahi kāmaʻa wela, akā ʻaʻohe uila i kūkulu ʻia i loko.

E like me ka mea i manaʻo ʻia, hōʻike ʻia ka A7R pani WiFi i hoʻohui ʻia a me NFC. E ʻae kēia mau mea hana hoʻopili i nā mea hoʻohana e hoʻouna i nā faile i kahi kelepona paʻalima a i ʻole papa a e kaohi i ke kāmela ma o ka hāmeʻa paʻa.

Weathersealed Sony A7R II aniani mea paʻi kiʻi e hoʻokuʻu ʻia i kēia ʻAukake

ʻO Sony A7RII kahi pahupaʻi uila i hiki ke kū i ka lepo, ka ona, a me nā mahana haʻahaʻa. Ana ka hāmeʻa ma kahi o 127 x 96 x 60mm / 5 x 3.78 x 2.36 iniha, ʻo ke kaupaona ʻana he 625 gram / 22.05 auneke me nā pila i hoʻokomo ʻia.

Hāʻawi ke kāmela aniani ʻole i ke ola o nā pila a hiki i nā kiʻi 290 ma ke kuleana hoʻokahi a me kekahi mau awa, e like me USB 2.0, HDMI, microphone, a me headphone.

Hoʻonohonoho ʻia ka lā hoʻokuʻu o ka A7R II i ʻAukake 2015. E lilo ke kāmela no ke kumu kūʻai o $ 3,200, ma kahi o $ 900 ʻoi aku ka pipiʻi ma mua o ka mea ma mua.
