I-lens variofocal: izinzuzo nezinsalela

I-lens varifocal yile lens ene-adjustable focal length. Izingoma zalolu hlobo zisetshenziselwa amakhamera (zihlomele kuphela ngama-lens alolu hlobo) namavidyo amavidyo (angaba kokubili ubude obugxile njalo futhi obuningi). I-lens variococal iqukethe uhlelo olulodwa lwe-optical, izingxenye zalo ezithuthukiswa ngokuhambisana nomunye nomunye, okuholela ekubeni ushintsho olubucayi (ukulungiswa) kobude obugxile futhi, ngokufanayo, isilinganiselo sesithombe ebubanzi obude. Noma kunjalo, ubukhali bokugxila kwezinto futhi ukuvula okuhlobeneyo akuguquki.

I-lens variofocal ngokulungiswa komuntu okukuvumela kukuguqula ubude obugxiliwe kabili, okwenza kube lula ukulungisa ukukhanya kwekhamera esithombeni esihle. Amadivaysi anezilawuli ezikude angashintsha ubude obugxile kusuka izikhathi ezingu-6 kuya kwezingu-50. Lawa lens asetshenziselwa ukuhlolwa kwevidiyo.

Ake sibone, futhi yiziphi izinzuzo nezinsalela zale divayisi, njenge-lens variofocal.

Enye yezinzuzo zedivayisi ukuthi ikuvumela ukuba ulungise i-angle yokubuka ngqo endaweni, uma ufaka ikhamera yevidiyo. Futhi-ke, emva kokufaka ikhamera, kungenzeka ukuthi ulungise ubude obugxile. Kule mfanelo yamadivayisi anjalo aphela. Manje ake sibheke ukwehluleka.

Ikhamera ene-lens varifocal idinga ukulungiswa, okungeyona elula ngaso sonke isikhathi, ngoba kuzodingeka uphathe imishini eyengeziwe ngaso sonke isikhathi (umhloli wokuhlola, ibhethri, njll). Ukulungiswa kwe-lens kuyinkimbinkimbi kakhulu, kubalulekile ukucacisa isilinganiso esiphezulu sobude obugxile nobukhali, futhi inqubo yenziwa ngezihlungi ezikhethekile (okubiza kakhulu), okungafihli isithombe. Ngakho, impendulo yokuqala iyilungiselelo eliyinkimbinkimbi.

I-lens variofocal inomkhawulokudonsa okubi kakhulu (ukukhanya) kuqhathaniswa nama-lens angunaphakade. Lokhu kubonakala ngokukhethekile emadivayisini ahlukahlukene (5-50), ikhwalithi yesithombe kusihlwa izoba yinto enyanyekayo. Ukuqoqa ukukhanya okuphansi kuyisibili esingahle.

Ingozi yesithathu ye-lens variofocal yukuthi ekugcineni ihlukumeza emathonyeni anomshini noma oshisayo. Ngenxa yalokho, emva kwezinyanga ezimbalwa, kuzodingeka ushintsho olungeziwe.

Okwesine okungalungile yintengo yomgomo onjalo, kuyabiza kakhulu kunomuntu ohleliwe.

Ukufingqa, ake sithi ama-variofocal lens, naphezu kokushiyeka kwabo, athandwa kakhulu futhi ayadingeka kakhulu kunezinkomba ezihleliwe. Noma kunjalo, kufanele kuqaphele ukuthi ukubuyekezwa kulesi sihloko kukhuluma kuphela ngamakhamera ahloselwe ukubhekwa kwevidiyo, ngoba kuphela abanokukhetha kwama-lens ahleliwe noma ayenziwe ngezifiso. Kumakhamera namakhamera, kusetshenziswa ama-optics ngokwezifiso kuphela.
