Hoʻolaha ʻia ka aniani ʻo Irix 15mm f / 2.4 no DSLR piha

Ua wehe ʻo Irix i kahi aniani i kuhikuhi ʻia me ka moemoeā o ka mea paʻi kiʻi. Loaʻa iā ia he 15mm f / 2.4 kikoʻī ākea ākea me ka nānā lima e hoʻolālā ʻia no nā kāmela DSLR piha.

Hoʻokahi ʻoihana i kaulana no ka hoʻouka ʻana i nā optics manual-focus-only me ke kūlana kiʻi ʻoi loa no DSLRs piha piha ʻo Zeiss. Hoʻokumu pū ka mea Kelemania i nā aniani autofocus, akā i kēia manawa he mea hoʻokūkū koʻikoʻi kāna no ka laina kuhikuhi manual.

No Irix ka hoʻokūkū, kahi i lawe wale i nā wahī o kahi optic kihi ākea me ka lōʻihi kiko o 15mm a me ka puka kiʻekiʻe o f / 2.4. E hoʻokuʻu ʻia ka huahana i kēia punawai no Canon, Nikon, a me Pentax DSLR, akā ma mua, e ʻike kāua i kāna mea e hāʻawi ai.

Hoʻolauna mua ʻo Irix i nā aniani nānā lima 15mm f / 2.4

Wahi a ka paʻi paʻi ua hele mai ka aniani Irix 15mm f / 2.4 me ka ʻenehana hou. ʻO nā ʻōnaehana i hoʻohui ʻia i loko o ka optic i ʻōlelo ʻia e lawe i nā hana lima i ka pae aʻe, no ka mea, he laka nui ka mea hoʻohana, kahi pālākiō hyperfocal, a pēlā hoʻi me ka kaomi pau ʻole i kā lākou hoʻolilo.

Hāʻawi ka Irix 15mm f / 2.4 ākea ākea i nā ʻenehana hou, nā hana ʻoi aku i ʻoi loa, a me ke anilā.

ʻO ka laka nui kahi hiʻohiʻona e ʻae i nā mea hoʻohana e laka i ke apo paʻa. Hiki ke hoʻohana ʻia e nā mea paʻi kiʻi ke maopopo lākou ua nānā pono lākou, no laila makemake lākou e paʻa ke apo nui i kahi.

Aia ka pālākiō hyperfocal e hōʻike i nā mea hoʻohana i ka hohonu o ke kahua no ka puka i koho ʻia, ʻoiai ke kaomi infinity e kani i kahi kani kaomi ke kau nā mea paʻi kiʻi i ka infinity. ʻO kēia ala, e ʻike nā mea hoʻohana ke nānā nei kā lākou maka aniani i ka pau ʻole.

Hāʻawi ka lens Irix 15mm f / 2.4 i ke ʻano kiʻi kiʻekiʻe

ʻO kekahi o nā hiʻohiʻona nui o ka aniani kona ʻano kiʻi. Hana nui ka lens Irix 15mm f / 2.4 i kēia keʻena, e like me ka mea i haʻi ʻia i ka hoʻokuʻu paʻi.

Hele mai ia me kahi hoʻonohonoho kūloko i loko o 15 mau lālā i 11 mau pūʻulu. Ke hāʻawi nei kahi ʻekolu o nā mea i kahi papa kuhikuhi kiʻekiʻe-refactive, ʻoiai he mau mea he Extra-Low Dispersion.

ʻElua mau mea hou aʻe he aspherical, no laila ke hoʻoliʻiliʻi holoʻokoʻa i nā aberrations chromatic a me nā distortions, ʻoiai e hoʻonui ana i ka ʻōlinolino i nā lihi. Hoʻohui ʻia, hōʻike kēia optic i kahi pale neutrino e hoʻoliʻiliʻi i ka lapalapa a me ka ʻuhane.

Canon, Nikon, a me Pentax mea hoʻohana e hiki ke kūʻai iā ia i ka makahiki 2016

Hoʻopilikino ʻia ke aniani o ka Irix 15mm f / 2.4, ʻo ia hoʻi pale ʻia ia i ka makū, kahe, a me ka lepo ke hoʻohana pū ʻia me kahi kāmela paʻi kiʻi.

E hoʻokuʻu ʻia ke kuhina ākea ākea i nā mana ʻelua: ʻO Blackstone, ka mea i kahakaha i nā kaha fluorescent a me kahi kino i hana ʻia me ka alumini a me ka magnesium, a me Firefly, kahi i loaʻa ke apo nui ergonomic a me kahi kūkulu ultra-lightweight.

E kaupaona ʻia ʻo Blackstone i ka 685 gram me ka Canon mount a me 653 gram me ka Nikon mount, ʻoiai ʻo Firefly e kaupaona iā 608 gram no nā kāmela Canon a, 581 mau pakuhi no nā kāmela Nikon.

Ua hōʻoia ʻo Irix e lilo ka optic i Canon EF, Nikon F, a me Pentax K mauna. E hoʻokuʻu ʻia ka aniani i kekahi manawa i kēia pūnāwai no kahi uku kumukūʻai i hōʻike ʻole ʻia.
