Ungayikhetha Njani Ilensi YeMacro Yezimboni? Umahluko Phakathi Kweelensi ZeMacro Zezimboni Neelensi ZeMacro Zemifanekiso

Iilensi ze-macro zoshishinoluhlobo olukhethekileyo lweelensi ezinkulu ezisetyenziswa kwizicelo zoshishino. Zihlala zinobukhulu obuphezulu kunye nesisombululo esihle, kwaye zifanelekile ukujonga nokurekhoda iinkcukacha zezinto ezincinci. Ngoko ke, ungayikhetha njani ilensi enkulu yezimboni?

1.Ungayikhetha njani ilensi ye-macro yezimboni?

Xa ukhetha ilensi ye-macro yezimboni, ezi zinto zilandelayo zinokuqwalaselwa ngokupheleleyo:

Uluhlu lobude befocal

Ubude befocal lens ze-industrial macro buhlala buphakathi kwe-40mm kunye ne-100mm, kwaye ungakhetha uluhlu olufanelekileyo lobude befocal ngokweemfuno zakho zokudubula. Ngokubanzi, ubude befocal obufutshane bufanelekile ekudubuleni kufutshane komntu othathweyo, ngelixa ubude befocal obude bufanelekile ekudubuleni umgama omde, nto leyo enokuhlula ngcono umntu othathweyo kunye nemvelaphi.

Imbobo

Okukhona i-aperture inkulu, kokukhona ilensi inokufunxa ukukhanya okungakumbi, nto leyo eluncedo ekuthatheni iifoto ezinkulu kwiindawo ezinokukhanya okuphantsi. Ukongeza, i-aperture enkulu inokufikelela kubunzulu obungaphantsi kwe-field effect, iqaqambise umxholo.

I-Aperture yenye yezona parameter zibalulekileyo zokukhetha

Ukwandiswa

Khetha ukukhulisa okufanelekileyo ngokweemfuno zakho zokudubula. Ngokubanzi, ukukhulisa okungu-1:1 kunokuhlangabezana neemfuno ezininzi zokudubula okukhulu. Ukuba kufuneka ukukhulisa okuphezulu, ungakhetha ilensi yobungcali ngakumbi.

Lumgangatho wesibuko se-ens

Izinto zelensi nazo zibalulekile. Ukukhetha iilensi zeglasi ezikhanyayo kunokunciphisa ngempumelelo ukuguquguquka kwe-chromatic kwaye kuphucule ukucaca komfanekiso kunye nokuveliswa kwakhona kombala.

Lisakhiwo se-ens

Cinga ngoyilo lwesakhiwo selensi, njengoyilo lwe-zoom yangaphakathi, umsebenzi wokulwa nokushukuma, njl.njl., ukuze kube lula ukudutyulwa ngcono kwe-macro.iilensi ze-macro zoshishinoinokuba ixhotyiswe ngomsebenzi wokulwa nokushukuma, onceda ukunciphisa ukufiphala okubangelwa kukushukuma kwekhamera xa udubula izinto ezinkulu.

Ixabiso leelensi

Khetha ilensi ye-macro efanelekileyo ngokwebhajethi yakho. Iilensi ezibiza kakhulu zihlala zisebenza ngcono ngokwe-optical, kodwa ungakhetha ilensi enexabiso eliphezulu ngokweemfuno zakho zokwenyani.

2.Umahluko phakathi kweelensi ze-macro zoshishino kunye neelensi ze-macro zefoto

Kukho umahluko phakathi kweelensi ze-macro zoshishino kunye neelensi ze-macro zefoto, ikakhulu ngokwendlela yoyilo kunye neemeko zokusetyenziswa:

Uyilofukutya

Iilensi ze-macro zemizi-mveliso ziyilwe ngokugxininisa ngakumbi ekusebenzeni nasekuqineni, kwaye zihlala ziqinile kwaye zineempawu ezifana nokumelana nothuli namanzi. Ngokwahlukileyo koko, iilensi ze-macro zefoto zigxila kakhulu ekusebenzeni kokukhanya kunye noyilo lobuhle, kwaye zihlala zicocekile ngakumbi ngenkangeleko.

Iimeko zokusetyenziswa

Iilensi ze-macro zoshishinozisetyenziswa kakhulu kwicandelo lemizi-mveliso, njengokufota nokuvavanya izinto ezincinci ezifana nezixhobo ze-elektroniki kunye neendawo zoomatshini. Iilensi ezinkulu zemifanekiso zisetyenziswa kakhulu ngabathandi bezithombe ukufota izinto ezincinci ezifana neentyatyambo nezinambuzane.

Uluhlu lobude befocal

Iilensi ze-macro zoshishino zihlala zinobude obufutshane be-focal, ezifanelekileyo ukufota izinto ezincinci kufutshane. Iilensi ze-macro fotografi zinokuba nobubanzi obubanzi be-focal ubude kwaye zinokuthwala ukudubula kwe-macro kumgama owahlukeneyo.

Ukwandiswa

Iilensi ze-macro zoshishinozihlala zine-magnifications ephezulu, enokubonisa iinkcukacha zezinto ngokweenkcukacha ezithe vetshe. Iilensi ze-macro ezinemifanekiso zihlala zine-magnifications ephantsi kwaye zilungele ngakumbi ukudubula izinto zemihla ngemihla eziqhelekileyo.

Iingcinga Zokugqibela:

Ukuba unomdla wokuthenga iintlobo ngeentlobo zeelensi zokujonga, ukuskena, iidrone, ikhaya elikrelekrele, okanye naluphi na olunye uhlobo lokusetyenziswa, sinazo izinto ozifunayo. Nxibelelana nathi namhlanje ukuze ufunde okungakumbi ngeelensi zethu kunye nezinye izixhobo.
