Kukuna hōʻailona hou ma ka pahu paʻi aniani Canon me ka EVF i kūkulu ʻia

Ua kālele ʻo Canon i nā mana hou o kāna ʻenehana Phase-Differ autofocus ʻenehana, kahi e kuhikuhi ai i nā mea nānā uila i nā kāmela aniani ʻole a me nā aniani translucent i nā kāmela DSLR.

Ma hope i Iulai 2013, ua hoʻolauna ʻo Canon i ka pahu paʻi kiʻi mua me ka ʻenehana Dual Dual Pixel CMOS, i kapa ʻia ʻo EOS 70D. Hoʻomaikaʻi kēia ʻōnaehana i ka hana AF ma ke ʻano Live View i ke kiʻi ʻana i nā kiʻi a me nā wikiō. Hoʻokumu ʻia ka ʻōnaehana ma ka ʻenehana Phase-Difference, i hoʻokaʻawale i nā pika i ʻelua mau photodiode e ʻae iā lākou e lālau i nā kukui hou aʻe a me ka wikiwiki o ka noʻonoʻo.

ʻIke ʻia ke ʻimi nei ka ʻoihana e hoʻomaikaʻi maikaʻi i ka mana hana o kēia ʻōnaehana, no ka mea ua kālele wale ia i kahi mana hou. ʻIke ʻia e hoʻohana ʻia ka ʻenehana Phase-Difference AF i nā kāmela mirrorless me nā viewfinders uila a me nā DSLR me nā aniani translucent.

ʻO kēia ka palapala hoʻohana patent Canon Phase-Difference AF. Hiki i kēia ʻenehana ke komo i loko o kahi kāmela aniani Canon me kahi nānā ʻike uila i kūkulu ʻia a i ʻole i kahi Canon DSLR me kahi aniani translucent built-in.

Hiki i ke kāmela aniani Canon ke hiki ke hoʻohana i kahi nānā uila

Ua nui nā kumuwaiwai i ʻōlelo e hoʻokuʻu ʻia ka Canon EOS M3 i nā mana ʻelua, hoʻokahi me ka viewfinder uila a me kekahi me ka ʻole o ia. Eia naʻe, ua hoʻolaha ʻia kēia k modelkohu a ʻaʻohe ona EVF.

Hiki paha i ka hui ʻo Iapana ke hoʻololi i kēia ʻano i ka wā e hiki mai ana, no ka mea ua hoʻopili ʻia i kahi ʻenehana autofocus hou e pili ana i ka pahupaʻiwikiō Canon mirrorless me kahi viewfinder uila i hoʻohui ʻia.

Wahi a Egami, Ke hana nei ʻo Canon ma kahi ʻenehana ʻĀpana AF ʻokoʻa e ʻae ai i nā MILC e autofocus me ka wikiwiki loa ke hoʻohana nā mea paʻi kiʻi i ka EVF.

Minamina, loaʻa kekahi mau kikoʻī e pili ana i ka pehea e hoʻokō ai ka ʻoihana i kēia ʻōnaehana. Eia naʻe, ʻo ka mea maikaʻi ke hōʻailona hope ia i ka manaʻo o ka ʻoihana e hoʻokumu i kahi kāmela mirrorless Canon me kahi EVF i kūkulu ʻia.

Hiki iā Canon ke hui pū me Sony i ka hana ʻana i DSLR me nā aniani translucent

ʻAʻole kū ka palapala noi patent ma aneʻi no ka mea hōʻike ia i ka ʻoiaʻiʻo e hana nei ʻo Canon i nā kāmela DSLR me nā aniani kalaka aniani.

ʻO nā kāmela A-mauna a Sony, e like me ka A99, nā aniani translucent. ʻO kekahi o nā kukui i ku i ke aniani hiki ke hele a hiki i ke kiʻina kiʻi, ʻoiai ke koena o ke kukui i ʻike ʻia i ke kiʻina ʻo Phase-Detection AF.

ʻAe kēia ʻenehana i ka pahupaʻikiʻi e hoʻolako i ka manawa piha-ʻike Loaʻa AF ʻoiai ke hoʻohana nei i kahi nānā. Eia nō naʻe, pono i ka mea nānā ke ʻano uila, e like me ka mea i hoʻohana ʻia ma nā kāmela ʻo Sony A-mount.

Ua lohe ʻia ka mea hana PlayStation e hooki i ka hana ʻana i nā DSLR me nā aniani semi-aniani, no ka mea, ua lawa ka mana o nā kiʻina kiʻi i kēia manawa e kākoʻo i kūkulu ʻia ʻo Phase-Detection AF.

E ʻike ʻia inā paha ʻaʻole e hoʻokuʻu ʻo Canon i kahi DSLR me kahi aniani translucent. Ma kēlā a me kēia ala, e lawe i kēia ʻike me kahi pinch o ka paʻakai a noho mau!
