Sigma 20mm f / 1.4 DG HSM ʻO ke aniani nani i lilo i aupuni

Ua hoʻolaha ʻo Sigma i nā maka aniani ākea 20mm o ka honua me kahi puka kiʻekiʻe o f / 1.4. E like me ka wānana ʻana o ka wili, e hoʻohui ʻia ka 20mm f / 1.4 DG HSM prime i ka papahana Art kiʻekiʻe ma ka hopena o kēia makahiki.

Ma ka waena o 2015, ua hōʻike ʻo Sigma i ka 24-35mm f / 2 DG HSM Art a ua ʻōlelo ʻia e pono i nā mea paʻi kiʻi ke kakali i nā mea maikaʻi hou aku i ka wā e hiki mai ana. Ua hōʻike ʻo Insiders ma ka liʻiliʻi e lilo i optic hou i kūhelu i kēia hāʻule a eia ia: ʻo 20mm f / 1.4 DG HSM Art.

E like me ka maʻamau, ʻaʻole mākou e kahaha i ka ʻoiaʻiʻo o kahi huahana Sigma kahi mea mua no ka ʻoihana kiʻi paʻi kiʻi. ʻO ka 20mm f / 1.4 DG HSM Art i hōʻike wale ʻia i ka aniani mua o ka honua no nā kāmela kiʻi piha e hōʻike i ka puka kiʻekiʻe o f / 1.4, kahi mea e pono ai i nā ʻano kukui liʻiliʻi.

ʻO Sigma 20mm f / 1.4 DG HSM Art lens i lilo i optic 20mm mua loa o ka honua me ka puka f / 1.4

Loaʻa i nā kāmele uila hou aku a nui aku megapixels. I mea e hoʻohana ai i ko lākou mana piha, pono i nā mea hana maka aniani e hāʻawi i nā optics kiʻekiʻe. ʻO kahi ʻoihana e ʻaneʻane e hāʻawi pinepine iā Sigma a ʻo kāna hana hou loa ka 20mm f / 1.4 DG HSM Art.

Pono e hana i ka mea hana Kepani me kahi mea e kūlike me nā koi o nā mea hoʻohana, no laila eia ka maka aniani mua piha o ka honua me ka 20mm kiko lōʻihi a me ka puka kiʻekiʻe e like me ka f / 1.4

Sigma 20mm f / 1.4 DG HSM Art ke aniani e kūpono no ke kukui haʻahaʻa e hoʻomaikaʻi i kāna puka kiʻekiʻe kiʻekiʻe.

Wahi a ka paʻi paʻi, hāʻawi ke aniani Sigma 20mm f / 1.4 DG HSM Art i ke ʻano kiʻi kiʻekiʻe ke hiki mai i nā hiʻohiʻona ʻāina, nā kiʻi paʻi o loko, nā lani hōkū, a me nā kiʻi paʻi.

Hoʻokumu ʻia nā aniani Sigma 20mm f / 1.4 DG HSM Art ma kahi hoʻolālā i loaʻa i 15 mau mea i nā hui 11. Hoʻopili ka hoʻonohonoho kūloko i ka F Low Dispersion (FLD) a me nā mea kūikawā Special Low Dispersion (SLD) me kahi puka 9-blade i hoʻopuni ʻia.

ʻO nā pakuhi MTF o ka aniani Sigma 20mm f / 1.4 DG HSM Art.

Hoʻohana ka huahana i kahi Hyper Sonic Motor i ʻōlelo ʻia e hoʻolako i ka autofocusing wikiwiki, hāmau. Ua hele a piha me ka barela i hana ʻia mai Thermally Stable Composite, no laila he optic paʻa ia, e like me ke koena o kona kaikaina Art-series.

Loaʻa ke apo lima lima lima i ka maka aniani ma ka ʻaoʻao o kahi pālākiō mamao no nā mea paʻi kiʻi e makemake i ka nānā ʻana e like me ka wā kahiko. Kaupaona ka optic i 950 mau auneke / 33.5 auneke, ʻoiai e ana ana iā 90.7mm i ke anawaena a me 129.8mm i ka lōʻihi.
