He mea nui ka lens Panel — ʻo ia nā “maka” nāna e hopu a hoʻopololei i ke kiʻi ma luna o ke kiʻiʻoniʻoni a i ʻole ka mea ʻike kikohoʻe.

Mālama nā Lens i ʻelua mau waiwai koʻikoʻi o ka mālamalama: ka nānā a me ka nui. ʻO ka manaʻo e pili ana i ke ʻano o ka paʻa ʻana o ke kiʻi, ʻoiai ʻo ka nui e hoʻoholo ai i ka nui o ke kiʻi i kuhi ʻia ma luna o ka mea ʻike a i ʻole ke kiʻiʻoniʻoni.

Hiki ke hoʻokaʻawale ʻia nā lens e like me ko lākou lōʻihi kikoʻī, i ana ʻia i nā millimeters (mm). ʻO ka ʻōlelo maʻamau, ʻoi aku ka maikaʻi o nā lens me kahi hiʻohiʻona ākea (12mm-35mm) no ke kiʻi ʻāina, ʻoiai ʻoi aku ka maikaʻi o nā lens me ka lōʻihi kikoʻī (100mm-800mm) no nā kiʻi kokoke e like me nā kiʻi a i ʻole nā ​​kiʻi holoholona hihiu. Aia kekahi mau lens telephoto e hāʻawi ana i kahi kihi ākea a me kahi lōʻihi kikoʻī i loko o ka lens hoʻokahi - kūpono no ka huakaʻi! Eia hou, hiki ke kūʻai ʻia nā ʻano lens kūikawā e like me nā lens macro a me ka fisheye no ka hopu ʻana i nā kiʻi kūʻokoʻa.

No laila inā ʻoe e hoʻomaka wale ana i ke kiʻi a nānā paha e hoʻomaikaʻi i kāu hāmeʻa, ʻo ka hoʻomaopopo ʻana i nā ʻano lens like ʻole e hiki ke kōkua iā ʻoe e hana i kahi koho ʻike i ke kūʻai ʻana i nā mea kāmela. Ma kēia alakaʻi e uhi mākou i nā mea āpau e pono ai ʻoe e ʻike e pili ana i nā ʻano lens kamera like ʻole a me nā mea e hoʻohana ʻia ai.

He aha nā Lenses?

He ʻāpana koʻikoʻi nā Lenses o kēlā me kēia ʻōnaehana kamera a he kuleana nui lākou i ka maikaʻi o nā kiʻi a lākou e hana ai. Hiki mai nā lens i nā ʻano nui, nā ʻano a me nā ʻano, mai nā lens lōʻihi paʻa a hiki i nā lens zoom. Ma muli o ke ʻano kiʻi āu e hana nei, pono paha ʻoe i nā ʻano lens like ʻole e loaʻa ai nā hopena i makemake ʻia. Ma kēiaʻatikala, e kūkākūkā mākou i nāʻano kumu o nā lens, a me ko lākou mau pono a me nā pōʻino.

Nā ʻano Lens

I ka wā e pili ana i nā lens, loaʻa i nā mea paʻi kiʻi nā koho like ʻole i loaʻa iā lākou. Mai nā ʻano kumu like nā maka maka a me nā lens zoom i nā lens kūikawā e like me nā lens ākea ākea a me nā lens telephoto, loaʻa i kēlā me kēia me kāna mau hiʻohiʻona ponoʻī. Ma ka hoʻomaopopo ʻana i ka ʻokoʻa ma waena o kēia mau ʻano lens, hiki i nā mea paʻi kiʻi ke koho i ka lens kūpono no kēlā me kēia kūlana.

Nā Leni Kūleʻa: ʻO nā lens prime nā lens lōʻihi e hiki ai ke ʻoi aku ka oi a me ka maopopo. Me ka lōʻihi hoʻokahi ʻaʻole hiki ke hoʻololi ʻia, he koho maikaʻi kēia no nā kiʻi alanui a me nā kau kiʻi.

Nā Leni Zoom: Hāʻawi nā lens zoom i ka versatility ʻoiai lākou e ʻae iā ʻoe e hoʻonui a i waho paha i nā lōʻihi kikoʻī like ʻole me ka ʻole e hoʻololi i waena o nā lens prime lehulehu. ʻO kēia nā koho kūpono no nā hanana a i ʻole nā ​​kiʻi haʻuki inā makemake ʻoe i ka maʻalahi i ka hopu ʻana i kāu mau kiʻi.

Nā Leni ākea ākea: ʻae nā lens ākea ākea iā ʻoe e hopu i nā hiʻohiʻona ākea me ka ʻole o ka hoʻokaʻawale ʻana ma nā kihi o ke kiʻi, e hoʻolilo iā lākou i mea kūpono no ke kiʻi ʻāina a i ʻole nā ​​kiʻi o loko me nā wahi ʻokoʻa.

Nā Leni Telephoto: Hiki iā ʻoe ke hopu i nā mea mamao me nā kikoʻī nui aʻo ka hoʻokaʻawale ʻana i kāu kumuhana mai kona ʻaoʻao e hoʻomaikaʻi i kona pāpaʻu. hohonu o ka mahina nā mea hiki. He kūpono kēia no nā holoholona hihiu a i ʻole nā ​​kiʻi hana i ka wā e hoʻāʻo ai e hoʻokokoke me ka ʻole e neʻe kokoke i ke kino.

Nā Leni Nui

ʻO nā lens prime nā lens prime a he hoʻokahi ka lōʻihi o kēia mau lens, ʻo ia hoʻi, ʻaʻole lākou e zoom. ʻOi aku ka liʻiliʻi a ʻoi aku ka māmā o kēia mau lens ma mua o nā zooms, a ʻoi aku ka liʻiliʻi o ke kumukūʻai. Eia naʻe, ʻo ka pana ʻana me nā lens prime, pono ʻoe e hoʻoneʻe i kou kino a hoʻohana paha i kou mau wāwae e hoʻololi i ka mamao ma waena o ʻoe a me ke kumuhana, e kūʻē i ka hoʻonui ʻana a i waho paha me kahi lens lōʻihi-focal-lōʻihi.

Ua ʻike ʻia nā lens Prime no ko lākou ʻoi aku ka maikaʻi o ka optical i hoʻohālikelike ʻia i ko lākou mau hoa zoom; ʻO nā hiʻohiʻona i ʻimi nui ʻia e hōʻike i ka hana hou ʻana o nā leo a me nā kala me ka oi maikaʻi loa ma ke kiʻi. Loaʻa kēia mau lens mai nā puka ākea ākea ma mua o nā lens zoom ma kekahi mau kikoʻī lōʻihi. Hoʻohui ʻia, ʻoi aku ka māmā o nā lens prime, e hoʻolilo iā lākou i kūpono no ke kiʻi huakaʻi a me ke kiʻi haʻahaʻa me nā puka ākea e like me f/2.8 a i ʻole ākea inā loaʻa.

I ka hōʻuluʻulu manaʻo, inā ʻoe e ʻimi nei i kahi komo kūpono i ke kiʻi me ka ʻole o ka hoʻohālikelike ʻana i ka maikaʻi, a laila ʻo nā lens prime kāu koho maikaʻi loa. ʻO ka nele o ka optical zoom i ka wā mua akā e aʻo koke ʻoe e hoʻoikaika iā ʻoe e lilo i mea noʻonoʻo ma ke ʻano o ka haku ʻana i nā kiʻi, hiki ke alakaʻi i nā holomua i ka loaʻa ʻana o nā kihi kūʻokoʻa a me nā ala i poina ʻole ʻia!

Nā Lens Zoom

ʻO nā lens zoom he papa nui o nā lens kamera a hiki ke hoʻohana nui i nā ʻano kiʻi like ʻole. Hāʻawi kēia mau lens iā ʻoe e hoʻololi i ko lākou lōʻihi kikoʻī, hāʻawi iā ʻoe i ka mana ʻoi aʻe ma mua o kahi lens paʻa-focal-lōʻihi. Hoʻopili ʻia nā lens zoom kokoke i nā ʻano o ka lōʻihi kikoʻī, akā ua hoʻokaʻawale ʻia ma ke ʻano he lens zoom wideangle (mai 15 a 35mm) a i ʻole nā ​​lens zoom telephoto (mai 70 a 300mm).

ʻOi aku ka nui o ka nānā ʻana o ka wideangle zoom ma mua o nā lens prime maʻamau a paʻa-focal-lōʻihi a kūpono loa no ka hopu ʻana i nā hiʻohiʻona nui a i ʻole nā ​​kumuhana mamao loa. Hāʻawi pū lākou i ka hohonu o ke kahua ma mua o nā telephoto zooms, e ʻoi aku ka maikaʻi no ke kiʻi ʻana i nā kiʻi me nā kumuhana he nui ma nā mamao like ʻole mai ke kāmela.

Hiki i nā telephoto zoom ke hoʻokokoke mai i nā mea mamao. He mea kūpono kēia no ka hoʻohana ʻana i nā haʻuki, nā holoholona hihiu, a me nā kiʻi kūlohelohe ʻoiai ʻaʻole pono ʻoe e neʻe kokoke i kāu kumuhana e like me nā zooms wideangle a i ʻole nā ​​lens prime. Eia naʻe, hāʻawi pinepine lākou i ka liʻiliʻi o ka hohonu ma mua o nā zooms wideangle, ʻo ia hoʻi he mea paʻakikī ke mālama i nā ʻāpana āpau o ke kiʻi i ka manawa hoʻokahi. Hoʻohui ʻia, pilikia pinepine lākou i ka chromatic aberration a me ka distortion lens i hoʻohālikelike ʻia me nā zooms wideangle ma muli o nā ʻōnaehana optical paʻakikī e pili ana i ka hana ʻana i kēlā kiʻekiʻe kiʻekiʻe.

ʻO nā lens telephoto he subcategory o nā lens e hoʻohana ana i ka hoʻolālā optical a me ka ʻenekinia kūikawā e hiki ai iā lākou ke hopu i nā mea i kahi mamao aku me ka ʻole e hoʻolōʻihi i ke kino kamera. Hoʻohana pinepine ʻia nā lens telephoto i ke kiʻi kiʻi a me ke kiʻi ʻāina, nā kiʻi hana a me nā kiʻi astrological.

Ma muli o ka lōʻihi o ka lens āu e koho ai, hiki i nā lens telephoto ke ʻano mai ka haʻahaʻa a i ka lōʻihi. Manaʻo ʻia kahi lens 50mm he haʻahaʻa aniani telephoto, ʻoiai ʻoi aku ka lōʻihi ma mua o 80mm i manaʻo ʻia he lens telephoto lōʻihi. Loaʻa i nā lens telephoto kahi kihi haiki o ka nānā ʻana, maikaʻi loa ke nānā pono i kāu kumuhana i nā kikoʻī nui loa mai kahi mamao aku.

ʻO ka lens telephoto .3 he laʻana o ka super-telephoto, ʻo ia hoʻi, he lōʻihi koʻikoʻi kona mai 300mm a 1200mm a ʻoi aku paha—e ʻae iā ʻoe e hopu i nā hana ʻoi aku me nā kikoʻī nui aʻe. Hoʻohana mau ʻia lākou no nā kiʻi kokoke e like me ke kiʻi haʻuki a me nā hālāwai ola hihiu e koi iā ʻoe e pili kokoke a pilikino me kāu kumuhana mai kahi mamao. Eia nō naʻe, ma muli o ko lākou nui pili a me ke kumukūʻai e kaupalena pinepine lākou i nā mea paʻi kiʻi ʻaʻole i loaʻa i ka lako a i ʻole ka waihona kālā e hoʻohana pono iā lākou - no laila, ʻo nā mea paʻi kiʻi haʻuki ʻoihana a i ʻole nā ​​​​mea paʻi kiʻi kūlohelohe a me nā holoholona hihiu hiki ke loaʻa i kēia mau mea pono ke pōmaikaʻi nui mai kēia ʻano kūikawā. o na lens.

-Prime lenses: Hoʻopaʻa ʻia nā lens prime i ka lōʻihi o ka focal hoʻokahi, e kūpono ana iā lākou no nā kūlana haʻahaʻa haʻahaʻa a me ke kiʻi kiʻi. ʻOi aku ka maikaʻi ma mua o nā lens zoom.

I ka wā e pili ana i nā lens a me nā kiʻi, ʻo ka Hoʻopuka F-u waiwai (a i ʻole Focal Length) o kahi lens e hōʻike ana i ka nui o ka mālamalama i hōʻiliʻili ʻia e ka mea ʻike kamepiula. ʻO ke kiʻekiʻe o ka F-stop, ʻoi aku ka liʻiliʻi o ka hopena o ka haʻalulu a i ʻole ka neʻe ʻana i ke kiʻi. ʻO kahi F-Stop liʻiliʻi e maʻalahi i ka mea paʻi kiʻi ke kiʻi i nā kiʻi ma nā kūlana haʻahaʻa. No ka laʻana, hiki i ka lens F/2.8 ke hoʻokomo i ʻelua mau māmā e like me ka lens F/4 a ʻehā manawa ʻoi aku ka nui o ka māmā e like me ka lens F/5.6.

Ke koho ʻana i kahi lens no kahi kiʻi i hāʻawi ʻia, pono e noʻonoʻo nā mea paʻi kiʻi i nā mea e like me ke kihi o ka ʻike, ka hohonu o ke kahua a me ka lawe ʻana i ka wā e hoʻoholo ai i ka lōʻihi kikoʻī kūpono no kā lākou pono. Hiki ke loaʻa ka lōʻihi mai ka 8mm ultra-wide fish eye a 1600mm super telephoto lens; akā naʻe, ʻo ka hapa nui o ka poʻe e pana ana me nā lens maʻamau e holo ana ma waena o nā lens ākea ākea 28mm a me nā lens telephoto 300mm. Ma waena o kēia mau pūʻulu lōʻihi kikoʻī ʻelua, nā koho maʻamau ka:

* 35mm: ʻO ka hapa nui o nā pahupaʻikiʻi pana i kēia nui ma ka paʻamau. He mea maʻamau ka lōʻihi kuʻuna mai ka wā i hoʻolaha ʻia ai ke kiʻi kiʻi ʻoniʻoni 35mm a hiki i nā mea paʻi kiʻi ke hopu i nā mea a ko mākou mau maka e ʻike ai ma ke ʻano kūlohelohe ma kēlā me kēia mamao mai ke kumuhana i paʻi ʻia.
**50mm: Kaulana ma waena o nā mea paʻi kiʻi kiʻi no ka mea hāʻawi lākou i ʻoi aku ka nui o ka hiki ke hoʻoheheʻe ʻia ʻoiai ke loaʻa nei ka hiʻohiʻona kūlohelohe i ke kiʻi ʻana i nā kumuhana kanaka ma kahi kokoke a mamao paha. kokoke a mamao loa paha mai kā lākou mau kumuhana.* 85 mm: Hoʻohana pinepine ʻia inā makemake ʻoe i nā haku mele ʻoi aku ka paʻakikī a me ka blur hope ʻoi aku ka maikaʻi ma mua o ka mea hiki ke loaʻa iā ʻoe me nā lōʻihi ʻē aʻe. no nā kiʻi haʻuki a i ʻole nā ​​holoholona hihiu kahi e pono ai ʻoe e kiʻi i nā kiʻi me nā hiʻohiʻona paʻa akā mālama pū i kahi mamao loa mai kāu mau kumuhana no nā kumu palekana (e laʻa, holoholona hihiu).

ʻO ka Aperture ka wehe ʻana o ka lens e komo ai ke kukui a hana i kahi kiʻi. Ana ʻia ka puka ma nā helu f a kuhikuhi ʻia e kekahi helu i ʻike ʻia he f-stop. Hāʻawi pū ka Aperture i ka nānā ʻana; ʻO nā puka ākea e hana i kahi hohonu pāpaʻu o ke kula, kahi e hiki ai i ka mea i ka mua ke nānā i ka nānā ʻana aʻo nā mea i ke kua i pohihihi. ʻO nā lens me kahi f-stop haʻahaʻa e like me ƒ/4 he mau lens wikiwiki, ʻo ia hoʻi, hiki iā lākou ke kiʻi koke i nā kiʻi a hāʻawi i ka hana maikaʻi i ka wā e pili ana i ke kiʻi māmā haʻahaʻa.

Me ka ƒ/4 aperture, inā ʻoe e nānā pono i kahi mea kokoke (e ʻōlelo ma waena o hoʻokahi a me ʻeono kapuaʻi), e ʻike ʻoe i ka hohonu pāpaʻu o ke kula, kahi wale nō kāu kumuhana e ʻoi aku ka maikaʻi a ʻoi aku ka maikaʻi o ke kua. I ke kiʻi ʻana i nā kiʻi a i ʻole nā ​​kiʻi macro me kahi mea e like me ƒ/4, pono ʻoe i nā kukui kūlohelohe maikaʻi maikaʻi e hana pū ai - he nui nā koho i loaʻa no ke kiʻi ʻana i nā kiʻi nani me kēia ʻano lens!

ʻO ka lens autofocus 0.5 hiki iā ʻoe ke nānā pono i ke kumuhana o kāu kiʻi, e hōʻemi ana i ka pono no ka nānā lima ʻana i ke kiʻi ʻana. ʻO ka hiki ke hoʻomau i kāu kumuhana i nā manawa a pau e koho maikaʻi ai kēia ʻano lens no ka hopu ʻana i nā kumuhana wikiwiki a ʻike ʻole paha - nā holoholona, ​​​​nā mea pāʻani, a i ʻole nā ​​mea e neʻe nei. Ke hoʻohui pū ʻia me kahi mea ʻike kiʻekiʻe, hiki i kēia ʻano lens ke kōkua iā ʻoe e hoʻokō i nā kiʻi ultra-sharp me ka pololei a me ke kūlike.

Hoʻohana nā lens autofocus 0.5 i kahi kaʻa kuʻekuʻe kūloko e hana pū me ka ʻōnaehana autofocus o ka pahupaʻikiʻi e hoʻopuka i ka hana kikoʻī wikiwiki a pololei. Kōkua kēia i ka hōʻemi nui ʻana i ka manawa e pono ai no ka hoʻoponopono ʻana i ka wā i hoʻokumu ʻia ai ka manaʻo, e kūpono ia no nā kiʻi wikiō a me nā kiʻi paʻi. Me ka hāʻawi ʻana i ka manaʻo pololei ma mua o nā lens manual, ʻoi aku ka hilinaʻi o kēia hoʻolālā lens ma lalo o ka hoʻololi ʻana i nā kūlana māmā e like me ka neʻe ʻana mai loko a i waho a i ʻole e hana ana i nā hiʻohiʻona haʻahaʻa haʻahaʻa e like me ke kiʻi haʻuki a me nā ʻāina pō.

I ka hopena, he mea nui e hoʻomaopopo i nā ʻano lens like ʻole a pehea e hana ai i mea e hoʻohana maikaʻi ai i kāu pahupaʻikiʻi. Aia nā ʻano lens paʻa like ʻole me nā lens hoʻololi a zoom hiki ke hoʻohana ʻia ma muli o ke ʻano o ke kiʻi āu e hana nei. ʻO ka hoʻomaopopo ʻana i nā ʻano, nā hana a me nā hiʻohiʻona e ʻae iā ʻoe e koho i ka lens maikaʻi loa no ka hana. E lawe i kekahi manawa i ke koho ʻana i kahi lens no kāu pahupaʻikiʻi, e noʻonoʻo i nā ʻano āpau, e hoʻokolohua me nā ʻano ʻano like ʻole a e ʻimi i ka mea kūpono loa i kāu mau pono.
