Canon EF 20-45mm f / 2.8-4 aniani i ka ulu ʻana

Ua kālele ʻo Canon i kekahi mau aniani i kēia manawa, me kahi zoom EF 20-45mm f / 2.8-4 ākea a me kahi EF-S 55-200mm f / 4-6.3 telephoto zoom, i hiki ke hōʻike ʻia i kekahi manawa i ka ʻaʻole lōʻihi loa.

Aia i ka mea āu e noi ai, ua ola a ʻaʻole paha paha ʻo Canon i ka hype i ka 2015 ke pili i nā hoʻolaha aniani. Ma kēlā me kēia ala, e hoʻomau ka ʻoihana i ka hoʻokumu ʻana i nā optika hou ma 2016 a, ma kahi o nā lono i ʻike ʻia, hiki iā ʻoe ke hoʻohui i ʻelua huahana hou aku i ka papa inoa.

Ua ʻike nā kumuwaiwai ma Iapana i nā palapala hoʻoilina no kekahi optics hou, e like me ka EF 20-45mm f / 2.8-4 no nā DSLR piha piha a me nā EF-S 55-200mm f / 4-6.3 no nā DSLR me nā kiʻina APS-C.

Canon EF 20-45mm f / 2.8-4 aniani i hoʻohuli ʻia no nā kāmela piha EOS DSLR

Ke ʻimi nei nā ʻoihana paʻi kiʻi āpau i nā ala hou e hoʻomaikaʻi ai i kā lākou hāʻawi. ʻAʻole hana ʻo Canon i kahi ʻokoʻa a, inā ʻoe e hoʻohana nei i kahi kāmela EOS piha piha, a laila hiki paha iā ʻoe ke kau i kou mau lima ma kahi aniani 20-45mm f / 2.8-4 koke.

ʻO ka hoʻonohonoho kūloko o ke aniani Canon EF 20-45mm f / 2.8-4.

Ua patent ka mea hana Kepanī i ʻehā optika i ka noi like. ʻEkolu mau aniani he 16-35mm mau hiʻohiʻona, ʻelua o lākou e loaʻa ana ka palena kiʻekiʻe o f / 2.8 a ʻo kekahi e hōʻike ana i ka puka kiʻekiʻe o f / 4.

ʻO ka mea hope loa, ʻo ka huahana ʻehā, he aniani Canon EF 20-45mm f / 2.8-4. Hōʻike ia i nā mea he 14 i nā hui he 10 me ka nui o ka aspherical a me ka Ultra Low Dispersion element no ka hoʻomaikaʻi ʻana i ke kūlana kiʻi.

Inā lilo ia i mea ʻoiaʻiʻo, a laila e hāʻawi ia i kahi mamao e nānā ana i ka mamao o 28 centimeter a me kahi ʻano e nānā ana i loko. Kūpono ia i ka laulā o ke aniani ākea a ʻaʻohe ona ʻenehana paʻa i hoʻohui ʻia, ʻoiai ke ʻano o ka puka kiʻekiʻe hiki ke uku ʻia.

Ma ke ʻano holoʻokoʻa, maikaʻi ia ma ka pepa a he wahi no kēlā huahana hou ma ka mākeke. I ka wā ma mua, ua kūʻai aku ʻo Canon i nā aniani 20-35mm f / 2.8L a me 20-35mm f / 3.5-4.5 i ka lehulehu, akā e lōʻihi ana ka lōʻihi o ke kikowaena a me kahi diaphragm ʻokoʻa i waena o kekahi.

Ua kiʻi ʻia kekahi aniani EF-S 55-200mm f / 4-6.3 STM ma Canon ma Iapana

ʻO nā aniani kaulike ʻē aʻe e pono ke haʻi ʻia ʻo ia ka weirder o ka pūpū. Ua hoʻoholo ʻokoʻa ʻia a komo ia i kahi optic EF-S 55-200mm f / 4-6.3 STM.

ʻO ka hoʻolālā kūloko o ke aniani Canon EF-S 55-200mm f / 4-6.3 STM, e like me ka mea i hōʻike ʻia i loko o kāna noi patent.

No ka mea ʻē aʻe ke kūʻai aku nei ʻo Canon i kahi hoʻohālikelike like, ʻoi aku ka maikaʻi a maikaʻi hoʻi: EF-S 55-250mm f / 4-5.6 IS STM. Aia kēia optic zoom zoom mai 2013 a ʻo ia nō loaʻa ma Amazon no $ 300.

E like me ka mea i ʻōlelo ʻia ma luna, ua kūpono ka nui e noʻonoʻo ana i kāna hana, no laila ʻo ka nūhou e pili ana kahi mana me ka lōʻihi kikoʻī liʻiliʻi a me ka puka mālie i ka hoʻomohala ʻana he mea hoʻopūʻiwa. Eia kekahi, ʻaʻohe o kēia anakahi i kahi ʻōnaehana hoʻopaʻa kiʻi i kūkulu ʻia i loko.

Eia nō naʻe, inā ua patent ia, a laila loaʻa iā ia ka manawa kūpono e hele mai ai i ka mākeke. Eia nō naʻe, ke hoʻokuʻu ʻia, e loaʻa paha kahi kumukūʻai liʻiliʻi loa. Noho kokoke iā Camyx e ʻike i nā kikoʻī e pili ana iā ia!
