Ua kālele ʻo Canon i kahi aniani hou e hāʻawi ana i kahi lōʻihi kikoʻī o 400mm, kahi puka kiʻekiʻe o f / 2.8, a me kahi mea hoʻonui i kūkulu ʻia e hoʻonui i ka lōʻihi kiko e 1.4x.

Ke hoʻokokoke nei mākou i ka Photokina 2014, hopohopo ʻaʻole e hoʻolaha nui nā ʻoihana i nā mahina aʻe.

E kali paha nā mea hana uila a me nā mea hana aniani no ka hōʻike ʻana o ka hanana i kā lākou hana hou loa. Inā heʻoiaʻiʻo paha kēia ʻaʻole paha, e hoʻomau nā ʻoihana i ka hōʻoia ʻana i kā lākou huahana.

Ua hana ʻeleu ʻo Canon i kēia ʻoihana i nā manawa i hala iho nei. ʻO ka manawa hope loa a mākou i kamaʻilio ai e pili ana i ka palapala Sila Nui Canon, pili ia i kahi 400mm f / 4 IS DO k modelkohu. I kēia manawa, ke nānā nei hoʻi mākou i kahi aniani 400mm, akā ʻo kahi e hōʻike ana i ka puka mālamalama o f / 2.8.

Canon 400mm f / 2.8 aniani i hoʻohuli ʻia i Iapana me ka hoʻopili 1.4x hoʻohui

ʻO kēia ke aniani o Canon EF 200-400mm f / 4L IS USM me kahi 1.4x extender i kūkulu ʻia. Ua pateni ka hui i kahi aniani hou me kahi 1.4x extender i hoʻohui ʻia, ʻoiai ʻo ka mana hou e haʻuki nei i kahi lōʻihi kikoʻī o 400mm a me kahi puka o f / 2.8.

Hele mai ka Canon 400mm f / 2.8 maka aniani me kahi pūʻiwa hoihoi. Hōʻike kēia aniani i kahi extender i kūkulu ʻia o 1.4x, e like me ka mea i loaʻa i nā aniani EF 200-400mm f / 4L IS USM, i hoʻolauna ʻia i Mei 2013.

ʻO ka EF 200-400mm f / 4L IS USM i ʻōlelo ʻia ʻo ia ka optic mua e hele mai me ka hoʻopili 1.4x hoʻohui. Ke hoʻohana ʻia, e hāʻawi ia i kahi lōʻihi kikoʻī o 280-560mm ma ke kumukūʻai o hoʻokahi f-stop, ʻo ia hoʻi ka kū o ka puka kiʻekiʻe ma f / 5.6.

Inā hoʻohana ʻo Canon i kahi ʻōnaehana like, a laila e hāʻawi ka aniani 400mm f / 2.8 i kahi lōʻihi kikoʻī o 560mm a me ka puka kiʻekiʻe o f / 4. E hauʻoli paha nā ʻona kamepiula ʻo EOS i ka lohe ʻana i kēia, akā ʻaʻole hōʻoia ka patent ʻana i kahi huahana e hoʻokuʻu ʻia ma ka mākeke.

Ke kūʻai aku nei ʻo Amazon i ke aniani Canon EF 200-400mm f / 4L IS USM me ka 1.4x extender i kūkulu ʻia i loko no kahi kumukūʻai ma kahi o $ 11,800.

Ke hoʻomau nei ʻo Canon i nā aniani kaulapa me ka lōʻihi kiko o 400mm

E like me ka mea i ʻōlelo ʻia ma luna, ua hoʻomake ʻo Canon i kekahi aniani 400mm i nā manawa hou. Hoʻopili ʻia kēlā mana me kahi puka kiʻekiʻe o f / 4 a me ka ʻenehana hoʻonā kiʻi.

Eia kekahi, ʻo ka mana 400mm f / 4 me nā mea optic diffractive, ʻo ia hoʻi e hoʻomaikaʻi ʻia ke ʻano o ke kiʻi, ʻoiai e hoʻemi ʻia ana ke kaupaona a me ka nui.

ʻO kā Canon "makahiki o nā aniani" ʻekolu wale nō optika i kēia manawa: ʻo ka EF 16-35mm f / 4L IS USM, ka EF-S 10-18mm f / 4.5-5.6 IS STM, a me ka EF-M 55-200mm f / 4.5-6.3 ʻO STM.

Eia nō naʻe, e hōʻike ʻia nā hiʻohiʻona hou aʻe ma Photokina 2014, no laila e nānā pono i kā mākou pūnaewele!
