E lawe i kāuʻike kiʻi kiʻi i ka pae aʻe
I ka hikiʻana mai i nā maka liʻiliʻi lōʻihi,ʻo ka mea nui loa e nānā ai i loko,ʻo ia ka hilinaʻi kiʻekiʻe, e hōʻikeʻia ana i nā millimeters. ʻO ka hapa nui o nā aniani ua ho'ākākaʻia e like me ka lōʻihi o ka 35 mm a iʻole ka liʻiliʻi, aʻo ia paha he mea nānā nui a iʻole nā hiʻohiʻona nānā. Akā, ma mua o kou liʻiliʻi i ka lōʻihi o kou makemake, ponoʻoe eʻike pono he mea like me kāu kamepiula, a iʻole paha e kūlike me nā leka i hāʻawiʻia. I ka manawa e hoʻokahe anaʻoe i kahi mamao, hiki iāʻoe ke hoʻomaka e nānā i ka hoʻopiliʻana, e like me ka lālā a iʻole ka'ōlena, kahi likeʻole a me nā hoʻonohonoho pane. Ma lalo nei, ua hōʻuluʻulu mākou i ka papa inoa o kekahi o nā leka uila ākea loa no Canon , Nikon a me nā kiʻi'ē aʻe.
ʻO ka pūʻali kupaianaha o ka whānui ākea ākea a me ka'ōkuhi liʻiliʻi, hiki ke koho iā Canon EF 16-35mm f / 4L IS USM mau leka. Hoʻohui i ka hoʻokumuʻana i ka hoʻolālā kiʻi, nā hoʻolaha kūikawā no ka hōʻemiʻana i ka hoʻokipa a me nā pono UDʻelua no ka emiʻana i nā kiʻi kiʻi, hiki i ke Canon ke hoʻokomo i ka nānāʻana i loko a me ka USM ring no ka hoʻokaeʻana i ka mīkini pololei a me ka wikiwiki. Hiki keʻikeʻia ka nānāʻana i nā manawa āpau me ka mamao o ka mamao mamao o 0.92 kapuaʻi ma'ō o ke kahakai holoʻokoʻa o ka lens.
Hoʻopiliʻia no nā kaulike a pau,ʻo kēia leonona Canon he lepo a me ka paʻakikū wai, e hiki ai iā ia ke hana ma nāʻoihana hoʻonaʻauao a me nāʻoihana-manawa a me nā manawa a pau. Ma waho o ka palekana e kū'ē i nā kumu, hiki i ka puka ākea o ke aniani Canon a me nā mauʻeiwa eiwa no ke kiʻiʻana i nā kiʻi nani a me nā haʻahaʻa.
Hōʻike nā hōʻike i kāna hana a me nā hualoaʻa kiʻi ma lalo o nāʻanoʻoi aku o nā kukui a me nā kiʻi kiʻi. Ma kahi o 1.4 paona wale nō, e hiki wawe ke nānāʻia ke kiwi Canon EF 16-35mm i kahi e hiki ai i nā mea o Canon DSLR keʻimi nei i ka mea maikaʻi loa ma ke kiʻiʻoki ākea.
I ka heleʻana i kahi koho no nā mea he nui o Canon DSLR,ʻo ka EF S 10-22m f / 3.5-4.5 he hui pū kekahi o kaʻilikai kiʻi a me ka waiwai i lilo ia i mea koho nui no ka nānā lewa. Hoʻohui pū i kahi hoʻolālā kiʻiʻokoʻa,ʻoihana kiʻekiʻe a me kahi nānā lima manawa lōʻihi me kahi wikiwiki o ke apo i ka wahie i ke ahi e hiki keʻike pono kēia Canon lens.
Me kahi mamao iki o 9.5 'īniha wale no ka nānā' ana, hiki i nā mea i kūpono i ka 3.6 x 5.4 'īniha ke hoʻopiha i ke kiʻi. ʻO ka lahilahi o ka nui o kēia leona e pāleona ana he 0.85 paona, aʻo ia ka mea iʻoi aku ka nui o ka māmā e kau ai i loko o keʻeke. ʻO nā kihi ākea mai ka lōʻihi o kēia lens i hoʻopaʻaʻia e hōʻailona ai i nā mea kiʻi kiʻiʻoihana like me kahi kūlike i kahi hemi 16-35mm. ʻO nā māmā lenserʻekolu, nā māmā Super-UD a me keʻano o ka mīkini USM kōkua a pau e hōʻoiaʻiʻo i ka maikaʻi o ka kiʻi.
ʻOiaiʻaʻole kahi hoʻokūkū hoʻokūkū i kūkuluʻia, pono ka hale māmā e mālama pono i kēia lelo ma kou lima i ka hopuʻana i nā kiʻi o ka mareʻana, i ka hanana hoʻolauleʻa aiʻole i ka kiʻi kiʻi'āina ma kahi papa'āina.
He paʻakikī maikai ka nānāʻana ma ka mea kūʻai, a ināʻoe e hoʻomau i ka huliʻana, makemakeʻoe e hōʻoiaʻoeʻaʻoleʻoe e hoʻokomo i kekahi mea e wāwahi ai i nā mahina wale nō. No laila, ke kamaʻilio neiʻoe i nā leka'ōnaehana, "ke kālā", ke'ōlelo neiʻoe e pili ana i kahi kūʻai o kahi $ 150 a $ 200. Ma waena o kēia mau maka, ke Nikon AF-S DX NIKKOR 35mm f / 1.8G lelani paha ka leka uila nui loa e hiki ai ke loaʻa no nā kiʻi kiʻi Nikon. Loaʻa i kahi lōʻihi o ka lōʻihi o ka 35mm, e pili pono ana i ka maka o kānaka. ʻO ia keʻano o nā kiʻi e hōʻike pono iā lākou iho i kahi āu i noʻonoʻo ai-ʻo ia hoʻi, ināʻoe eʻike i kāu mea e hana nei. ʻO kēia leki'ōnika heʻoi aʻe ka palena o f / 1.8 a me ka liʻiliʻi o f / 22. Aia kekahi ultrasonic autofocus (AF) motor me ka nānāʻana i nā manawa manawa piha. A i loaʻa kahi mea a pau ma lalo o $ 200 wale nō.
No kaʻoihanaʻoi aku o nā kaha ākea loa i kēia lā,ʻo ka Sigma 8-16mm f / 4.5-5.6 DC HSM FLD AF he koho koʻikoʻi loa no nā mea kuleana o Canon, Nikon, Pentax, a me Sony DSLR. ʻO ka leki hoʻokahi-o-a-ʻano,ʻo ka Sigma ka mea mua e hāʻawi i kahi lōʻihi o ka lōʻihi o 8mm. Hanaʻia me nāʻikepili kiʻi APS-C ma ka naʻau, ke hāʻawi nei nā leni i kahi mākaʻi like likeʻole i nā lelo 12-24mm.
Hoʻohui houʻo Sigma i nā meaʻoniʻoni FLD hou, ua kōkua ka leka i ka ukuʻana no ka hoʻopauʻiaʻana o ke kala a me ka hoʻoponopono kalaʻana ma ka hoʻolālāʻana i nā kiʻi maikaʻi loa i loko o kona holoʻana. Hiki i ka hoʻokomoʻana o kaʻenehana HSM ka hiki i ke kikowaena'ōkuhi e lilo i ka mechanical a me ka manual me kahi mamao o ka mamao o ka mamao o 9.4 inisi mai ke kumuhana wale nō.
Ma ka hopena, ua hanaʻo Sigma i nā lekaʻoi aku iʻoi aku ma mua o ke kiʻiʻana o ke kiʻi'āina, eʻike ana i ka hoʻolālā, i nā hale o ka hale, i ka photojournalism, i ka kiʻiʻana i nā kiʻi male a me nā mea'ē aʻe. ʻO ke 1.22 paona paona a he 4.17 ink i ka lōʻihi e hoʻohālikelike a maʻalahi hoʻi, no laila ua kūpono maikaʻi i loko o kaʻeke pō, ka peʻapeʻa, a me ka pēke kāmera i hoʻolaʻaʻia.
Inā makemakeʻoe e hopu i ka nani kupaianaha o ka Grand Canyon a iʻole kekahi mau hiʻohiʻona'ē aʻe, e makemake paha pahaʻoe i nā leki o ke kukui ultra wide-angle, e like me keʻano o nā leka me kahi lōʻihi lōʻihi o 15 mm. No nā Nikola shooters, aia ka Sigma 10-20mm f / 3.5 EX DC HSM. ʻO ka'ōmaʻa kū paʻa a me ke kikowaena o nā wahi pōkole nui he mea kūpono ia no nā kipa a me ka hoʻolālā, akā, he mea kūpono hoʻi ia no nā kiʻi kiʻiʻoihanaʻoihana. Loaʻa iā ia he motika sono-sonic no nā mīkini kūmā a me ka wikiwiki, a me kahi puʻupuʻu pīpī e hoʻopiʻi i nā kukui'ē aʻe aʻokiʻoki i ka nānāʻana i loko. ʻO ia ke kikowaena waena o ka laulā ākea ākea, akāʻo ka tech i hope o kēia mau polokalamu liʻiliʻi e hilinaʻi i nā mea kiʻi kiʻiʻoi loa. Aia kekahi mauʻano no Canon, Pentax a me Sony DSLR. ʻAʻole paha ia he hele maikaʻi i nā lens, akā, he mea maikaʻi loa ia no ka hōʻiliʻiliʻana i nā lelo.
ʻO kekahi koho koho hoʻolālā no nā mea kani Canon,ʻo ka EF-S 24mm f / 2.8 STM kūpono loa no kaʻano whānui-angle. Loaʻa ka lōʻihi o ka 24 mm a me ka pukaʻoi loa o f / 2.8. ʻO ia keʻano o nā lelo māmā a me ka māmā ma ka papa helu EF-S o nā leaniani Canon. Loaʻa iā ia ke'ōkoʻa manawa'ōkole holoʻokoʻa ma kahi o kahi Shot AF (autofocus) mode. Hōʻike ia i nā kiʻi nui me kahi wikiwiki wikiwiki, a ua liʻiliʻi ia e hiki ai i loko o kekahi pēke pahu. ʻO ke kumukūʻai kēiaʻaʻole ponoʻoe e hopohopo nui e pili ana i ke kanikauʻana i ke kūʻai, akā ināʻoe he mea hoʻohanaʻoihana nui me kahi koina lelo nui. E noʻonoʻo i kēia i kahi kānana inā he Canon shooterʻoe e nānā ana e kūʻai i kou leki ākea mua loa, akā,ʻaʻole makemakeʻoe e hoʻolilo i ka nui o ke kālā.
Hoʻoukaʻo Sigma i kāna leka uila Mark II i nā lā ma mua. ʻO ka lemu e hoʻoʻaniʻana i ke aniani liʻiliʻi liʻiliʻi me kahi pāpale multilayer e hoʻemi ana i ka haunaele a lawe mai i ka nui ma ka likeʻole. ʻO ka leka hoʻi he mau lōʻihi, me nā pale nani a me nā mea mua a me nā hope a me ke kauʻana i ka wela.
ʻO kekahi hana hou e hoʻololi ana i ka puka mai af / 4-5.6 ka pākēnaʻe kalana i kahi f / 4 mau, me, me kahi alaʻoi aku iʻoi aku ka maikaʻi-nui, e hana i nā kiʻi kaha kiʻi. No ka mea he pukahāhāhāhāhāhāhāhāhā / 4 āpau o ke kahakai holoʻokoʻa, uaʻoi aku ka māmā o ke kukui ma mua o ka mea i hāʻawi aku i nā mea kiʻi kiʻi wikiwiki wikiwiki i ka wikiwiki no kaʻoihana kiʻi a me ke kiʻi. ʻO ka lens heʻoi aku i ka 4.9x magnification, me ke kelehana Hyper-Sonic Motor e hāʻawi ana i nā mīkini liʻiliʻi a me ka wikiwiki i ka wā e kiʻi ana i nā kiʻi ma kahi lōʻihi.
