I-Cine vs Lens Yezithombe: Ungakhetha kanjani ilensi efanele yevidiyo

ngo kim Kubuyekezwe: June 28, 2022

Ungakwazi ukuqopha ngelensi evamile kukhamera yakho yevidiyo noma i-DSLR, kodwa uma udinga ukulawula okwengeziwe, ikhwalithi noma ukuthwebula izithombe ezithile, kungase kube isikhathi sokulahla ilensi “yekhithi” evamile futhi wandise izikhali zakho.

Nawa amanye amathiphu asebenzayo wokukhetha ilensi yevidiyo.

Ingabe udinga ngempela ilensi entsha?

Abaqophi bangase bakhathazeke kakhulu ngemishini yekhamera futhi baqoqe zonke izinhlobo ze-knick-knacks abangazisebenzisi. Ilensi enhle ayikwenzi umthwebuli wevidiyo ongcono.

Bheka kahle onakho nalokho okushodayo. Iziphi izithombe ozidingayo ongeke ukwazi ukuzithwebula okwamanje? Ingabe ikhwalithi yelensi yakho yamanje imaphakathi kakhulu noma ayanele?

Ngabe ufuna i-Prime noma i-Zoom?

A I-Prime lens ikhawulelwe kubude obugxilile/okugxilwe kukho okukodwa, isb. I-Tele noma i-Wide, kodwa hhayi kokubili.

Lokhu kunezinzuzo eziningana ngamalensi alinganayo; intengo iphansi uma kuqhathaniswa, ubukhali nekhwalithi ilungile, isisindo sivame ukuba ngaphansi futhi ukuzwela kokukhanya kuvame ukuba ngcono kune- Ilensi yokusondeza.

Nge-Zoom lens ungakwazi ukulungisa izinga lokusondeza ngaphandle kokushintsha amalensi. Kusebenza kakhulu ukwenza okubhaliwe futhi udinga isikhala esincane esikhwameni sakho sekhamera.

Ingabe udinga ilensi ekhethekile?

Ukuze uthole amashothi akhethekile noma isitayela esithile esibonakalayo ungakhetha ilensi eyengeziwe:

• lenses ikakhulukazi i-Macro shots, lapho uvame ukuthatha izithombe ezinemininingwane njengezinambuzane noma ubucwebe. Amalensi ajwayelekile awanawo amandla okugxila eduze kwelensi
• Noma ilensi Yeso Lezinhlanzi ene-engeli ebanzi kakhulu. Ungasebenzisa lokhu ezindaweni ezincane, noma ukulingisa amakhamera wesenzo.
• Uma ungathanda umphumela we-bokeh/ukufiphala (ukujula kwenkambu encane) kumashothi akho lapho okungaphambili kuphela kubukhali, ungafinyelela lokhu kalula ngokusheshisa (okuzwela ukukhanya) I-telephoto lens.
• Ngelensi ye-engeli ebanzi ungarekhoda isithombe esibanzi futhi ngesikhathi esifanayo isithombe sizinze kakhulu kunalapho udubula ubanjwe ngesandla. Lokhu kuyanconywa futhi uma usebenza nama-gimbals/steadicams.

Ukuzinza

Uma unekhamera ngaphandle kokuzinzisa, ungakhetha ilensi enokusimama. Ungayivula noma uyikhubaze ngokwezidingo zakho.

Ukuqopha ngekhamera, ebanjwa ngesandla noma ehlombe, lokhu empeleni kufanele ube nakho uma kungekho ukuqiniswa kwesithombe (IBIS) ekhamera.

I-Autofocus

Uma uqopha ngaphansi kwezimo ezilawulwayo, cishe uzogxila mathupha.

Uma uqopha imibiko, noma uma udinga ukuphendula ngokushesha esimweni, noma uma usebenza ne- gimbal (ezinye izinketho ezinhle esizibuyekezile lapha), kuyasiza ukusebenzisa ilensi ene-autofocus.

Ilensi yesinema

Abaningi be-DSLR kanye (nezinga lokungena) abathwebuli bevidiyo bekhamera yesinema basebenzisa ilensi yesithombe “evamile”. I-Cine lens yakhelwe ngokukhethekile ukuqoshwa futhi inezici ezilandelayo:

Ungasetha ukugxila ngesandla ngokunembe kakhulu nangokushelela, ukushintsha indawo yokuvula/imbobo akunasinyathelo, azikho izinkinga ngokuphefumula ilensi kanye nekhwalithi yokwakha ihlale iyinhle kakhulu. Okubi ukuthi i-lens ivame ukubiza futhi iyasinda.

Umehluko phakathi kwelensi yesine kanye nelensi yezithombe

Unezinhlobo ezahlukene zamalensi ezinhlelo zokusebenza ezahlukene. Esigabeni esiphezulu ungakhetha phakathi kwelensi yezithombe kanye ne-a cine lens.

Uma usebenza ekukhiqizeni ifilimu ngesabelomali esihloniphekile, kunethuba lokuthi uzosebenza nama-cine lens. Yini eyenza la ma-lens akhetheke kangaka, futhi kungani emba eqolo?

Isisindo esilinganayo nosayizi welensi yesine

Ukuvumelana kubaluleke kakhulu ekukhiqizweni kwefilimu.

Awufuni ukusetha kabusha eyakho ibhokisi le-matte (ezinye izinketho ezinhle lapha ngendlela) bese ulandela ukugxila lapho ushintsha amalensi. Yingakho uchungechunge lwama-cine lens lunobukhulu obufanayo futhi cishe isisindo esifanayo, kungakhathaliseki ukuthi i-lens ebanzi noma ye-telephoto.

Umbala nokugqama kuyalingana

Ezithombeni, ungaphinda uhluke ngombala futhi uqhathanise namalensi ahlukene. Ngefilimu akulula kakhulu uma ucezu ngalunye lunokushisa okuhlukile kombala nokubukeka.

Yingakho ama-cine lens enzelwe ukuhlinzeka ngokungafani okufanayo nezici zombala, kungakhathaliseki ukuthi hlobo luni lwamalensi.

Ukuphefumula kwelensi, ukuphefumula okugxilile kanye ne-parfocal

Uma usebenzisa i-zoom lens, kubalulekile nge-cine lens ukuthi iphuzu lokugxila lihlale lifana. Uma kufanele ugxile futhi ngemva kokusondeza, lokho kuyacasula kakhulu.

Kukhona namalensi lapho isitshalo sesithombe sishintsha khona ngesikhathi sokugxila (ukuphefumula ilensi). Awukufuni lokho uma uthwebula imuvi.

I-Vignetting kanye ne-T-Stop

Ilensi ine-curvature ukuze ilensi ithole ukukhanya okuncane ohlangothini kunaphakathi nendawo. Nge-cine lens, lo mehluko ulinganiselwe ngangokunokwenzeka.

Uma isithombe sinyakaza, ungawubona umehluko ekukhanyeni kangcono kakhulu kunesithombe. Ama-F-stops asetshenziswa ezithombeni, ama-T-stop efilimu.

I-F-stop ibonisa inani lethiyori lokukhanya elidlula ilensi, i-T-stop ibonisa ukuthi kungakanani ukukhanya okushaya ngempela inzwa yokukhanya ngakho-ke iyinkomba engcono futhi engaguquki.

I-cine lens yangempela ivame ukubiza kakhulu kunelensi yesithombe. Ngoba kwesinye isikhathi kufanele uqophe isikhathi sezinyanga, ukungaguquguquki kubaluleke kakhulu.

Ngaphezu kwalokho, ungalindela izici eziphakeme zamalensi ngaphansi kwezimo ezinzima zokukhanyisa ezifana nokukhanyisa emuva, ukungafani okuphezulu nokuchayeka ngokweqile. Ikhwalithi yokwakha kanye nokwakhiwa kwe-lens kuqinile kakhulu.

Abenzi bamafilimu abaningi baqasha ama-cine lens ngoba intengo yokuthenga iphezulu kakhulu.

Ngokuqinisekile ungathatha izithombe ezinhle kakhulu ngamalensi ezithombe, kodwa ama-cine lens aqinisekisa ukuthi wazi kahle ukuthi ilensi yenzani ngaphansi kwazo zonke izimo, futhi lokho kungonga isikhathi ngemva kokukhiqizwa.

F-Stop noma T-Stop?

The F-Misa kwaziwa ngabathwebuli bevidiyo abaningi, kukhombisa ukuthi kungakanani ukukhanya okungena ngaphakathi.

Kodwa i-lens yakhiwe izingxenye zengilazi ezihlukene ezibonisa ukukhanya, futhi ngaleyo ndlela iphinde ivimbe ukukhanya.

I-T-Stop isetshenziswa kakhulu namalensi eCinema (Cine) futhi ikhombisa ukuthi kungakanani ukukhanya okuye kwadlula, futhi lokho kungaba kuncane kakhulu.

Isiphetho

Kunezinto eziningi okufanele uzicabangele lapho uthenga ilensi entsha. Ekugcineni, ukukhetha okubaluleke kakhulu; ngidinga ilensi entsha? Okokuqala, cabanga ngalokho ofuna ukukuthwebula futhi uthole ilensi efanele yakho, hhayi ngenye indlela.
