Canon EF-S 20mm f / 2.8 STM aniani i hoʻohuli ʻia no APS-C DSLR

Ua kālele ʻo Canon i kahi aniani EF-S 20mm f / 2.8 STM ākea ākea no nā kāmela EOS DSLR o ka hui me nā kiʻi kiʻi APS-C-nui.

Nui nā aniani i pio i ka wā hou e nā hui lehulehu, e like me Canon. ʻAʻole hoʻopau ka mea kūʻai kiʻi kāmela nui loa o ka honua i ka hoʻomohala huahana a me kahi palapala kila hou he hōʻike no kēia ʻoiaʻiʻo.

Ua ʻae ʻia ka lentent Canon EF-S 20mm f / 2.8 STM i Iapana a hoʻolaha ʻo ia iā ia iho ma ke ʻano he optic prime-angle nui loa no DSLRs me nā sensor APS-C e hāʻawi i kahi puka mālamalama kūpono no ke kī ʻana o ke kukui haʻahaʻa.

ʻO kēia ka hoʻolālā kūloko o ke aniani Canon EF-S 20mm f / 2.8 STM, e like me ka mea i ʻike ʻia ma kāna palapala noi palapala Sila Nui.

Canon EF-S 20mm f / 2.8 STM maka aniani i wehe ʻia i Iapana

Hiki ke hoʻokuʻu ʻia i kahi aniani mua ākea e ka Canon i kekahi manawa i ka wā e hiki mai ana. ʻO ka huahana i nīnau ʻia ua pateni ʻia ma Iapana a me he mea lā he 20mm f / 2.8 optic i hoʻolālā ʻia no EF-S-mauna DSLR.

E hāʻawi ia i kahi 35mm kiko kiko lōʻihi like o 32mm ke kau ʻia ma nā kāmela DSLR me nā kiʻi kiʻi APS-C-nui. Mālamalama kona puka ākea no ka loko, ke alanui a me ka paʻi kiʻi kahiki i nā wahi kukui liʻiliʻi, no laila hiki ke lilo i aniani maʻalahi no nā mea hoʻohana EOS 7D Mark II.

Ke hāʻawi nei ka ʻoihana Kepani i kahi aniani f / 2.8 STM ākea ākea no nā DSLR moʻo EOS me nā ʻikepili APS-C. Eia nō naʻe, he lōʻihi ka lōʻihi o ka huahana o 24mm a ʻo ia ka unit pancake mahalo i kona lōʻihi o 22.8mm / 0.9 iniha. Minamina, ʻaʻole e lilo ka aniani Canon EF-S 20mm f / 2.8 STM i kumu hoʻohālike pancake e like me ka noi ʻana o ka palapala Sila e kū ana kona lōʻihi ma 64mm / 2.51 iniha. ʻO ka lens EF-S 24mm f / 2.8 STM pancake Aia ma Amazon no ke kumu kūʻai ma lalo o $ 150.

ʻO kēia aniani ākea ākea e hāʻawi i ka autofocus hāmau

Ua waiho ʻo Canon no ka palapala Sila Nui ma Kēkēmapa 6, 2013. Ua ʻae ʻia e ke keʻena hoʻokele ma Iapana i ka lā 18 o Iune, 2015. Hele mai ke kuhina nui ākea me kahi Stepping Motor i ʻōlelo ʻia e hāʻawi i kahi autofocusing mālie a maikaʻi.

E like me ka maʻamau, pono mākou e hoʻomanaʻo iā ʻoe i ka patent ʻana i kahi huahana ʻaʻole ia he manaʻo e hoʻokuʻu ʻia ka huahana i ka wā e hiki mai ana a i ʻole i nā makahiki aʻe. Ke hoʻokolohua nei nā ʻoihana i mea e ʻike ai inā hiki ke hiki i kahi huahana no ka mākeke, no laila mai mālama i kou hanu i ka hoʻomaka ʻana o ke aniani Canon EF-S 20mm f / 2.8 STM.

I kēia manawa, e nānā pono iā Camyx no nā nūhou hou aʻe a me nā lono mai ka honua kiʻi paʻi kiʻi!
