na kim Hoʻololi: June 28, 2022

ho'okokoke nā lelo ʻo ia kekahi o nā mea paʻi kiʻi nui loa, e hāʻawi ana i ka mea paʻi kiʻi i kahi ākea o nā hiʻohiʻona a me nā koho.

Hiki i ka lens zoom ke kōkua i ka hana ʻana i nā kiʻi kupanaha me nā hopena bokeh nani, a i ʻole e hopu i nā kumuhana mamao me ka maopopo a me ka pololei.

Ma kēia ʻatikala, e nānā hohonu mākou i ke ʻano o ka lens zoom, ka mea hiki ke hana, a me ka manawa e hoʻohana ai ia no kāu mau papahana kiʻi.

Wehewehe o ka Lens Zoom

I ke kiʻi kiʻi, ʻo ka lens zoom he ʻano lens me ka lōʻihi o ke kiko. Ua ʻike ʻia ka hiki ke hoʻololi i ka lōʻihi kikoʻī he zooming. Me ka lens zoom, hiki i nā mea paʻi kiʻi ke hoʻololi koke i ko lākou ʻike i ke kumuhana i hopu ʻia ma ka hoʻoponopono ʻana i ka lōʻihi o ke kiko.

Hoʻohana nā lens zoom i nā lens kūloko i hoʻolālā ʻia e neʻe i ka pilina o kekahi me kekahi i mea e loaʻa ai nā nui like ʻole o ke kiʻi ma nā mamao like ʻole mai kahi mea. ʻIke ʻia kēlā me kēia ʻano lens zoom e kona laulā - no ka laʻana, 18-55 mm a i ʻole 70-200 mm - e hōʻike ana i ka lōʻihi pōkole a lōʻihi loa e hiki ke hoʻonohonoho ʻia i ka lens. ʻO ka maʻamau, ʻoi aku ka mamao o kāu kiʻi mai kāu kumuhana (e laʻa, hele i hope), ʻoi aku ka nui o kāu kiʻi; ʻo ka mea ʻē aʻe, ke kokoke ʻoe, e liʻiliʻi (e laʻa, hele i mua).

Loaʻa ka nui o nā zooms i nā lens 35mm. ʻO ia ke kumu e hāʻawi lākou i ka maʻalahi no ka mea ua kūpono lākou no nā mamao pana like ʻole a me ka hoʻohālikelike ʻana iā lākou i ʻoi aku ka maʻalahi ma mua o nā lens prime, e hōʻike ana i nā lōʻihi paʻa ʻaʻole hiki ke hoʻoponopono ʻia me ka ʻole o ka hoʻololi ʻana i nā lens a i ʻole ka hoʻopili ʻana i nā mea waho e like me nā teleconverters. Hāʻawi pinepine ʻo Zoom i ka ʻoi aku ka maikaʻi ma mua o nā mana mua.

Nā ʻano Lens Zoom

Hiki mai nā lens zoom i nā ʻano like ʻole a me ka nui a ʻike ʻia e ko lākou laulā lōʻihi - mai ka pōkole a i ka lōʻihi. ʻO ka haʻahaʻa o ka helu, ʻoi aku ka laulā o ka ʻike; ʻo ke kiʻekiʻe o ka helu, ʻoi aku ka liʻiliʻi. Hiki ke hoʻokaʻawale ʻia nā lens zoom i ʻekolu mau ʻāpana: nā zooms ākea ākea, nā zoom maʻamau, a me nā zoom telephoto.

Hāʻawi nā lens zoom ākea ākea i kahi kihi o ka ʻike i ʻoi aku ka laulā ma mua o ka mea hiki iā ʻoe ke loaʻa me kahi leki lōʻihi paʻa a i ʻole kahi lens zoom maʻamau. He koho maikaʻi kēia inā makemake ʻoe e hopu i nā panoramas ākea a i ʻole e hoʻopili i nā hiʻohiʻona nui o waho i kāu kiʻi no ka mea e hoʻopaʻa lākou i nā mea mamao e hōʻemi ana i ka distortion kuanaʻike a hiki iā ʻoe ke hopu i nā mea āpau i loko o kāu kiʻi.

Loaʻa i nā lens zoom maʻamau ka lōʻihi kikoʻī ma kahi o 24 a 70mm ma ka hapa nui o nā kumu hoʻohālike. Hāʻawi lākou i ka maʻalahi ma mua o nā lens lōʻihi paʻa e hoʻomaikaʻi i ko lākou hiki ke hoʻololi wikiwiki mai nā kiʻi waena ākea a kokoke. He kūpono kēia mau ʻano lens zoom no ka hoʻohana multifunctional e like me ke kiʻi huakaʻi, ka hana palapala, nā hanana i loko, ke kiʻi ʻana i nā kiʻi maʻamau a i ʻole nā ​​​​paʻi kiʻi i kēlā me kēia lā.

Hōʻike ʻia nā lens zoom telephoto i nā lōʻihi kikoʻī lōʻihi e hoʻomaka ana ma kahi o 70mm a ʻoi aku paha a hiki i kahi mau haneli millimeters (a ʻoi aku paha ke kiʻekiʻe). ʻOi aku ka maikaʻi o kēia mau ʻano lens i ka hana ʻana i nā kumuhana mamao i ke kiʻi ʻana i nā ʻāina, nā kiʻi holoholona hihiu a me nā hanana haʻuki me ka pono ʻole o ka nui o nā mea e like me nā tripods a me nā monopods ma muli o kā lākou mau stabilizer optical ikaika e hōʻemi i ka haʻalulu kamera.

maika

Hāʻawi nā lens zoom i ka versatility i nā mea paʻi kiʻi, no ka mea hāʻawi lākou i kahi kihi ākea o ka ʻike a me ka hiki ke hoʻonui a hopu i nā kikoʻī hou aku. He mea maikaʻi nā lens zoom no ke kiʻi ʻana i nā ʻāina a no ke kiʻi ʻana i nā holoholona hihiu pono e hoʻonui ʻia no ka nānā pono ʻana mai kahi mamao aku. Aia kekahi mau pono ʻē aʻe no ka zoom lens a mākou e nānā ai i kēia manawa.

Hua'ōlelo

Hāʻawi nā lens Zoom i ka maʻalahi no nā mea paʻi kiʻi o kēlā me kēia ʻano, inā paha he poʻe loea ʻike a ʻoluʻolu paha me nā lako ʻoi aku ka holomua. ʻO kēia no ka mea hiki i nā lens zoom ke hoʻololi i ka lōʻihi o ka lens - e ʻae iā ʻoe e koho i kahi hiʻohiʻona ākea, a i ʻole telephoto ma muli o ka mea kūpono i ke ʻano. ʻO kēia hiki ke hoʻololi i waena o nā ʻano lōʻihi kikoʻī kūpono i mea maikaʻi no nā poʻe hoʻomaka, hiki iā lākou ke aʻo pehea e haku pono ai i kā lākou mau kiʻi, a me nā mea maikaʻi e nānā ana e hana i nā kiʻi kupanaha.

Hiki i nā lens zoom ke wehe i nā manawa no ka hoʻomohala ʻana - ʻoi loa me ke kiʻi kiʻi. ʻAʻole hiki iā lākou ke hopu i nā kiʻi kokoke a me nā kiʻi paʻa paʻakikī inā ʻoe e hoʻohana ana i kahi lens prime (lens lōʻihi paʻa), akā hiki iā ʻoe ke hoʻololi i waena o nā laula a me nā hiʻohiʻona i ka wā o ka pana. A ma muli o ka hoʻolako ʻia ʻana o kekahi o kēia mau ʻano lens me nā hiʻohiʻona hoʻopaʻa kiʻi, e maʻalahi ka loaʻa ʻana o nā kiʻi ʻoi aku ka liʻiliʻi me ka hilinaʻi ʻole i ka wikiwiki pani lōʻihi a i ʻole ka wikiwiki kiʻiʻoniʻoni.

Hoʻohui ʻia kēia mau hiʻohiʻona i makemake ʻia nā lens zoom no nā ʻano hiʻohiʻona he nui - mai nā kiʻi kiʻi ʻāina kahi e pono ai ke kiʻi i kahi kaʻawale no ka nānā pono ʻana me ka ʻole e hoʻolōʻihi iā ʻoe iho; kiʻi haʻuki kahi e neʻe wikiwiki ai nā kumuhana a koi i ka pololei kikoʻī; kiʻi holoholona hihiu mai kahi mamao palekana; kiʻi kiʻi macro kahi kūpono nā hoʻonohonoho puka haiki; a nui hou aku! ʻO ka mea hope loa, hāʻawi nā lens zoom i ka hiki ʻole ke hāʻawi i nā lens prime - no laila ʻo ka wehe ʻana i ka noʻonoʻo i nā koho like ʻole e alakaʻi wale i kou mākaukau i nā kuhikuhi hou!

Kaha Kiʻi kiʻi

I ka hoʻohana ʻana i kahi lens zoom, pili pono ka maikaʻi o ke kiʻi i nā hiʻohiʻona o ka lens kikoʻī i hoʻohana ʻia. Ma ke kumu kūʻai haʻahaʻa, ʻo ka hapa nui o nā lens zoom ʻaʻole e hāʻawi i kahi kiʻi ʻoi loa e like me ka lens prime - nona nā mea i loko e kōkua i ka ʻoi o ke kiʻi. Eia nō naʻe, ʻo ka holomua o kēia mau lā i ka hana ʻana i nā lens ke haki nei i kēlā mau pale a he nui nā koho no nā lens zoom maikaʻi me ka hoʻonā maikaʻi loa a me ka ʻokoʻa i nā lōʻihi kikoʻī.

Hiki i nā lens zoom ke hāʻawi i ka maʻalahi i ka wā e pili ana i nā kūlana pana a me nā hiʻohiʻona, e hāʻawi ana i nā mea paʻi kiʻi i ka mana noʻonoʻo o kā lākou mau kiʻi. Ma ka hoʻololi ʻana i ka lōʻihi kiko, hiki iā lākou ke hoʻololi maʻalahi i ko lākou kahua o ka nānā ʻana i ka wā e mālama ana i ke kāmela ma kahi kūlana paʻa e pili ana i kā lākou kumuhana. Hiki ke hoʻohana pono kēia i ke kiʻi ʻana ma nā wahi paʻa a i ʻole nā ​​wahi i hoʻopaʻa ʻia e kaupalena ʻia ai ka hiki o ka mea paʻi kiʻi ke haku pono i kā lākou kiʻi me nā ʻano lens ʻē aʻe. ʻO kekahi pōmaikaʻi koʻikoʻi ma aneʻi ʻaʻole ʻoe e hoʻopili hou i nā lens prime he nui inā ʻaʻole ʻoe makemake - akā hiki iā ʻoe ke hoʻohana i hoʻokahi lens zoom versatile e uhi ana i kāu mau lōʻihi i makemake ʻia me ka hoʻonā maikaʻi a me ka hoʻohālikelike.

Uku-kūpono

Hiki i ka lens zoom ke ala maikaʻi loa e kau ai i kāu DSLR ma kāna mau kaʻina. He emi ke kumu kūʻai o nā lens zoom ma mua o nā lens prime, nona ka lōʻihi o ke kiko. ʻOi aku ka māmā a ʻoi aku ka paʻakikī o nā lens zoom, he mea kōkua ia no ka huakaʻi a me nā ʻāina, a me ke kiʻi kiʻi kiʻi kiʻi a i ʻole ke alanui. Eia kekahi, ʻo ka loaʻa ʻana o ka hiki ke hoʻololi i ka lōʻihi o ke alo mai ka kihi ākea a hiki i ke telephoto ʻo ia ka mea ʻaʻole pono ʻoe i nā lens prime me nā lōʻihi kikoʻī like ʻole e uhi i kāu mau pono āpau - e mālama i ke kālā ma ke kaʻa.

ʻO ka hope, inā kūʻai ʻoe i lens zoom me ka hoʻopaʻa kiʻi kiʻi (IS) i kūkulu ʻia, hiki iā ʻoe ke hopu i nā kiʻi ʻoniʻoni ʻoiai ke paʻa lima ʻana i ka wikiwiki pani ʻaʻole hiki ke loaʻa me ka ʻole o IS. E ʻae kēia iā ʻoe e pana me ka ʻole o ka huki ʻana i kahi tripod nui a i ʻole nā ​​​​mauna ʻē aʻe no ke kūpaʻa hou aʻe e ʻoi aku ka maikaʻi o ka manawa a me ka ikaika i hoʻohana ʻia no ka hoʻonohonoho ʻana a me ka haki ʻana o nā mea hana.

I ka manawa e hoʻohana ai i kahi Lens Zoom

ʻO ka hana ʻana i ke koho kūpono o ka lens i ka wā e pana ana hiki ke loaʻa ka hopena nui i ka maikaʻi o kāu mau kiʻi a me nā wikiō. Ke koho ʻana i kahi lens, pono e ʻike i ka wā e hoʻohana ai i kahi lens zoom a me ka wā e hele ai no kahi lens lōʻihi paʻa. Hiki ke hoʻohana nui ʻia nā lens zoom no nā hiʻohiʻona pana like ʻole. E nānā kāua i ka wā e hoʻohana ai ʻoe i kahi lens zoom a pehea e pōmaikaʻi ai kāu kiʻi.

ʻIke Pūnaewele

I ka hoʻohana ʻana i kahi Lens Zoom no nā kiʻi kiʻi ʻāina, pono ʻoe e ʻike ʻaʻole e mālama ka hapa nui o nā lens zoom i ko lākou mau kikoʻī lōʻihi ke hoʻohālikelike ʻia me nā lens prime. Eia naʻe, me kēlā ʻōlelo, ʻo kekahi mau hiʻohiʻona i hui pū ʻia me ka hiki ke hoʻoponopono maʻalahi i kāu haku mele me ka ʻole e hele a hoʻololi paha i ke kūlana o kāu pahupaʻikiʻi hiki ke kūpono i ka hoʻopukapuka ʻana i kahi lens zoom.

He kūpono nā lens kihi ākea (14 - 24mm) no ka hopu ʻana i nā ʻāina ākea a me nā hiʻohiʻona nui, ʻoiai ʻo 24 - 70mm a i ʻole 24 - 105mm maʻamau ke ʻano i manaʻo ʻia i ka wā e ʻimi nei i kahi lens kumu āpau. No nā ʻāina ʻokoʻa ʻē aʻe, e like me nā puʻu mauna koʻikoʻi, nā holoholona hihiu i nā wahi / nā mea mālama holoholona a me nā kiʻi astro, 70 - 300mm a ʻoi aku ka maʻalahi no ka hopu ʻana i nā kiʻi ākea me ka hiki ʻana i ke kelepona i loko o ke kiʻi like.

ʻO kēlā me kēia ʻano o ke kiʻi Landscape i makemake nui ʻia iā ʻoe, aia paha kahi lens zoom e kōkua i ka hopu ʻana i nā kiʻi nani. ʻO ke kī ʻo ke koho ʻana i kahi e kūpono i kāu kālā a me nā pono hana.

Kolepa Kiʻi

Loaʻa pinepine ʻia ke kiʻi paʻi kiʻi me ka lens zoom. Hiki iā ʻoe ke hana i nā kiʻi kupaianaha o ka poʻe me ka ʻole o ka neʻe ʻana a hoʻonohonoho hou iā lākou i mea e loaʻa ai ke kiʻi a me ka haku mele. ʻO ka mea ʻē aʻe, inā hiki iā ʻoe ke hoʻohana i kahi lens prime, e hāʻawi ia iā ʻoe i kahi hiʻohiʻona ʻē aʻe no ka mea hāʻawi ia i kahi ākea ākea o ka nānā ʻana - ʻo ia hoʻi, ua kaupalena ʻia nā mea āu e ʻike ai ma o ka nānā ʻana no laila ʻaʻole liʻiliʻi kāu lumi wiggle i ka wā e haku ai i kāu. kiʻi kiʻi. No laila, nui nā mea paʻi kiʻi kiʻi ʻoihana e koho i nā lens telephoto a i ʻole nā ​​​​lensa telephoto no kā lākou mau kiʻi ma muli o ka maʻalahi o ka hiki ke hoʻonui i waho a i waho ma muli o nā pono o kā lākou kumuhana (a i ʻole ke ʻano o ka hopena hana a lākou e makemake ai e hoʻokō. ). Hoʻohana pinepine ʻia nā lens telephoto no ke kiʻi haʻuki ma muli o ko lākou hiki ke hopu i nā mea mamao mamao ma kahi kokoke. ʻO ka loaʻa ʻana o ka lōʻihi e hāʻawi i nā mea paʻi kiʻi i nā koho ʻē aʻe i ke kiʻi ʻana me ka mālamalama maoli, no ka mea hiki iā lākou ke hoʻonui a hoʻemi paha i ka mamao ma waena o lākou a me kā lākou kumuhana ʻoiai e mālama mau ana i nā mea i loko o ke kiʻi.

Kiʻi Haʻuki a me nā holoholona hihiu

Pono nā kiʻi haʻuki a me nā holoholona hihiu i nā wikiwiki pani wikiwiki a pono paha e kiʻi i kahi kumuhana neʻe hoʻokahi mai kahi mamao aku. Ma ia mau kūlana, hiki i ke kelepona a i ʻole ka lens zoom ke kōkua e hoʻokō i ka pana i makemake ʻia. Hiki mai nā lens telephoto ma nā ʻano nui a me nā lōʻihi, me 70mm kahi wahi maikaʻi loa e hoʻomaka ai inā ʻoe e hoʻomaka nei.

Hāʻawi kēia mau lens iā ʻoe e hoʻonui i kāu kumuhana me ka hāʻawi ʻana iā ʻoe i wahi e hoʻihoʻi ai e like me ka mea e pono ai. Hiki i nā wikiwiki pani wikiwiki ke ho'ōki i ka hana a mālama pono i nā mea āpau, no laila he mea nui ka loaʻa ʻana o ka lens wikiwiki no nā haʻuki a me nā kiʻi holoholona hihiu. ʻOi aku ka wikiwiki o ka aperture a me ke kiko kiko o ka lens, ʻoi aku ka maʻalahi o kāu mau kiʻi.

Ua kūpono nā lens telephoto no nā hana me ka liʻiliʻi o ka neʻe a me nā haʻuki e pili ana i nā wahi ākea nui e like me nā hanana track-and-field a me ka heihei kaʻa. Hiki ke kiʻi maʻalahi ʻia nā hāmeʻa kahi e hoʻokaʻawale ʻia ai nā mea pāʻani e nā mamao e like me ke kolepa, ka holo ʻana a i ʻole ka heʻenalu me ka hoʻohana ʻana i ka lens telephoto, no ka mea, hopu ia i nā kikoʻī mai kahi mamao aku ma mua o ka nui o nā ʻano lens ʻē aʻe i hiki ke kiʻi.

No laila, inā makemake ʻoe i ke kiʻi ʻana i nā holoholona hihiu a i ʻole nā ​​kiʻi haʻuki i kēlā me kēia manawa, ʻo ka hoʻokomo ʻana i kahi lens telephoto 70-300mm maikaʻi loa e hāʻawi iā ʻoe i nā hoʻihoʻi maikaʻi ma ke ʻano o nā kiʻi i hoʻomaikaʻi ʻia. Hiki iā ʻoe ke hopu maʻalahi i ka nui o nā kikoʻī i hāʻawi ʻia e kēia mau kumuhana koʻikoʻi me ka ʻae ʻana i nā hiʻohiʻona pili kokoke i hiki ʻole ke loaʻa me nā lens "kit" kuʻuna e like me 18-55mm zooms i hui pinepine ʻia me nā SLR digital ke kūʻai hou ʻia.

Panina

I ka hopena, hāʻawi nā lens zoom i nā mea paʻi kiʻi me kahi mea hana maʻalahi a maʻalahi. Hāʻawi lākou iā ʻoe e hele wikiwiki mai kahi kihi ākea i kahi nānā telephoto me ka ʻole e hoʻololi i nā lens. ʻO ka ʻike ʻana i ka wā e hoʻohana ai i kahi lens zoom hiki ke kōkua iā ʻoe e hoʻomaikaʻi i kāu kiʻi. No laila, inā paha ʻoe e paʻi ana i nā ʻāina, nā kiʻi, nā kiʻi huakaʻi, a i ʻole kekahi mea ʻē aʻe, hiki i kahi lens zoom ke koho maikaʻi loa.

hōʻuluʻulu manaʻo

ʻO ka hōʻuluʻulu manaʻo, ʻo ka lens zoom he ʻano lens kamera e hiki ai iā ʻoe ke nānā pono i nā mea ma nā mamao like ʻole. Loaʻa iā ia ka hiki ke "zoom in" a "zoom out" e hoʻololi i ke kahua o ka ʻike ma ke kiʻi e like me ka mea e pono ai. He mea maʻalahi loa nā lens zoom, e hoʻolilo iā lākou i mea kūpono no nā kumu kiʻi like ʻole e like me nā ʻāina, nā kiʻi, nā kiʻi haʻuki, nā kiʻi holoholona hihiu, a me nā mea hou aku.

I ka hoʻoholo ʻana i ka lens zoom e hoʻohui i kāu hōʻiliʻili, pono e noʻonoʻo i nā mea e like me ke kiko o ka lōʻihi o ke alo (ākea a i ʻole telephoto), ka nui aperture kiʻekiʻe, ka maikaʻi o ke kūkulu ʻana (metal vs plastic), ke kaumaha a me ka nui o ka lens. ʻAʻole pili i ka lens zoom āu e koho ai, e hōʻoia e hāʻawi iā ʻoe i ka hana maikaʻi loa no kāu mau pono kiʻi kikoʻī.

Aloha ʻoe, ʻo wau ʻo Kim, he makuahine a he mea hoihoi hoʻi me ka ʻike i ka hana ʻana i ka media a me ka hoʻomohala pūnaewele. Nui koʻu makemake i ke kaha kiʻi a me ka hoʻoulu ʻana, a ke luʻu mua nei au i ka honua hoʻomaha. Me kaʻu blog, ke kaʻana nei au i kaʻu mau ʻike me ʻoukou.
