Iyini ilensi yokugxila engaguquki?

Njengoba igama libonisa, ailensi yokugxila engaguqukiUhlobo lwelensi yezithombe ngobude obugxile obunqunyelwe, obungenakushintshwa futhi luhambisane nelensi yokusondeza.

Ukukhuluma, amalensi agxile agxile ngokuvamile anokuhlobisa okukhudlwana kanye nekhwalithi ephezulu yokubona, okwenza balungele ukuthatha izithombe ezisezingeni eliphakeme.

Umehluko phakathi kwamalensi agxile ahleliwe kanye namalensi wokusondeza

Ilensi yokugxila engaguquki kanye nelensi yokusondeza izinhlobo ezimbili ezijwayelekile zamalensi wekhamera, futhi umehluko wazo ophambili ulele ekutheni ubude obugxile buyakwazi. Banezinzuzo zabo lapho zisetshenziswa ezimweni ezihlukile zohlelo.

Isibonelo, ilensi egxile ehleliwe ilungele ukusetshenziswa kwezimo zokukhanyisa okwanele, ukuphishekela izindikimba eziphakeme zesithombe, nezindikimba eziqinile zokudubula, ngenkathi ilensi yokudubula ilungele izigcawu ezidinga ukusondeza kwezithombe.

Ilensi Egxilwe Ekuhlelweni

Ubude obugxile

Ubude obugxile belensi egxile ekugxilwe kuyo, njenge-50mm, 85mm, njll. Ilensi yokusondeza ingaguqula ubude obugxile ngokujikeleza noma ukucindezela nokudonsa umgqomo welensi, ukuvumela ukukhetha okuguqukayo phakathi kwe-angle ebanzi ne-telephoto.

Oukusebenza kwe-ptical

Ngokuvamile, ailensi yokugxila engaguqukiInekhwalithi engcono ye-Optical kune-lens ye-zoom ngoba ukuklanywa kwayo kulula futhi akudingi ukucatshangelwa kokunyakaza kwamalensi noma izakhiwo eziyinkimbinkimbi ze-optical. Ukukhuluma, amalensi agxile ahleliwe ngokuvamile anokuhlaselwa okuphezulu (ngenani elincane le-F), elinganikeza ikhwalithi yesithombe engcono, okukhanyayo okukhanyayo okulula, kanye nemiphumela engcono yokufiphaza.

Kepha manje ngokuthuthukiswa kobuchwepheshe, amanye ama-lens aqhakazile aphezulu angafinyelela ezingeni lelensi yokugxila engaguquki ngokuya ngokusebenza kwe-optical.

Isisindo nevolumu

Ukwakheka kwelensi egxile ekuhlolweni kulula, ngokuvamile kuncane futhi kube lula ngosayizi. Ukwakheka kwelensi yokusondeza kuyinkimbinkimbi, okubandakanya ama-lens amaningi, ngakho-ke kuvame ukuba nzima kakhulu futhi kukhudlwana, okungenzeka kungabi lula kakhulu ukuthi abathwebuli bezithombe basebenzise.

Indlela yokudubula

Ukugcwala okugxile kokugxilweAma-S alungele ukudubula izigcawu ezithile noma izifundo ezithile, njengoba ubude bangempela bungalungiswa, futhi amalensi afanele adinga ukukhethwa ngokusekelwe ebangeni lokudubula.

Ilensi yokusondeza ivumelana nezimo futhi ingaguqula ubude obugxile ngokuya ngezidingo zokudubula ngaphandle kokushintsha isikhundla sokudubula. Ilungele izigcawu ezidinga ushintsho oluguqukayo ekudubuleni ibanga ne-angle.
