Ilensi yombono womatshiniyilensi eyenzelwe ukusetyenziswa kwiinkqubo zokubona koomatshini, ezaziwa ngokuba ziilensi zekhamera zoshishino. Iinkqubo zokubona koomatshini zihlala ziquka iikhamera zoshishino, iilensi, imithombo yokukhanya, kunye nesoftware yokucubungula imifanekiso.
Zisetyenziselwa ukuqokelela, ukucubungula, kunye nokuhlalutya imifanekiso ngokuzenzekelayo ukuze zigwebe ngokuzenzekelayo umgangatho wezinto zokusebenza okanye zigqibezele ukulinganisa indawo ngokuchanekileyo ngaphandle kokudibana. Zihlala zisetyenziselwa ukulinganisa ngokuchanekileyo, ukuhlanganisa ngokuzenzekelayo, uvavanyo olungonakalisiyo, ukufumanisa iziphene, ukuhamba kwerobhothi kunye nezinye iinkalo ezininzi.
1.Yintoni ekufuneka uyiqwalasele xa ukhetha iilensi zokubona koomatshini?
Xa ukhethaiilensi zokubona koomatshini, kufuneka uqwalasele izinto ezahlukeneyo ukuze ufumane ilensi ekufaneleyo. Ezi zinto zilandelayo zixhaphakile:
Indawo yokujonga (i-FOV) kunye nomgama wokusebenza (i-WD).
Ummandla wombono kunye nomgama wokusebenza zimisela ukuba into enkulu kangakanani onokuyibona kunye nomgama ukusuka kwilensi ukuya kwinto.
Uhlobo lwekhamera oluhambelanayo kunye nobukhulu besenzisi.
Ilensi oyikhethayo kufuneka ihambelane nekhamera yakho, kwaye ukugoba komfanekiso welensi kufuneka kube ngaphezulu okanye kulingane nomgama othe tyaba wesenzi.
Umqadi wesiganeko somqadi odluliselweyo.
Kubalulekile ukucacisa ukuba isicelo sakho sifuna ukugqwetheka okuphantsi, isisombululo esiphezulu, ubunzulu obukhulu okanye ulungiselelo lwelensi enkulu yokuvuleka.
Ubungakanani bento kunye nezakhono zokusombulula.
Ubungakanani bento ofuna ukuyibona kunye nokuba isisombululo sayo sincinci kangakanani kufuneka kucace, nto leyo echaza ukuba inkulu kangakanani indawo yokujonga kunye nokuba zingaphi ii-pixels kwikhamera oyifunayo.
Eiimeko zendalo.
Ukuba uneemfuno ezikhethekileyo zokusingqongileyo, ezinje ngokumelana nomothuko, uthuli okanye amanzi angangeni, kuya kufuneka ukhethe ilensi enokuhlangabezana nezi mfuno.
Uhlahlo lwabiwo-mali lweendleko.
Uhlobo lwendleko onokulufikelela luya kuchaphazela uhlobo lwelensi kunye nomzekelo owukhethayo ekugqibeleni.
Ilensi yokubona yomatshini
2.Indlela yokwahlulahlula iilensi zombono womatshini
Kukho izinto ezininzi ekufuneka ziqwalaselwe xa ukhetha iilensi.Iilensi zokubona koomatshiniinokwahlulwahlulwa ibe ziintlobo ezahlukeneyo ngokwemigangatho eyahlukeneyo:
Ngokwendlela yobude be-focal, ingahlulwahlulwa ibe:
Ilensi yokugxila ezinzileyo (ubude befokha buzinzile kwaye abunakulungiswa), ilensi yokusondeza (ubude befokha buyalungiseka kwaye ukusebenza kuyaguquguquka).
Ngokwendlela yokuvula, ingahlulwahlulwa ibe:
Ilensi yokuvula ngesandla (ukuvula kufuneka kulungiswe ngesandla), ilensi yokuvula ngokuzenzekelayo (ilensi ingayilungisa ngokuzenzekelayo i-ukuvula ngokwesibane esingqongileyo).
Ngokweemfuno zesisombululo somfanekiso, ingahlulwahlulwa ibe:
Iilensi zesisombululo esiqhelekileyo (ezifanelekileyo kwiimfuno zemifanekiso ngokubanzi ezifana nokubeka esweni okuqhelekileyo kunye nokuhlolwa komgangatho), iilensi zesisombululo esiphezulu (ezifanelekileyo ukubonwa ngokuchanekileyo, ukuthathwa kwemifanekiso ngesantya esiphezulu kunye nezinye izicelo ezineemfuno zesisombululo esiphezulu).
Ngokwesayizi ye-sensor, ingahlulwahlulwa ibe:
Iilensi zefomathi yesensor ezincinci (ezifanelekileyo kwiisensor ezincinci ezifana ne-1/4″, 1/3″, 1/2″, njl.njl.), iilensi zefomathi yesensor ephakathi (ezifanelekileyo kwiisensor eziphakathi ezifana ne-2/3″, 1″, njl.njl.), iilensi zefomathi yesensor ezinkulu (zeesensor ezipheleleyo ezingama-35mm okanye ezinkulu).
Ngokwendlela yomfanekiso, ingahlulwahlulwa ibe:
Ilensi yomfanekiso we-monochrome (ingathatha imifanekiso emnyama namhlophe kuphela), ilensi yomfanekiso wemibala (ingathatha imifanekiso yemibala).
Ngokweemfuno ezizodwa zokusebenza, inokwahlulwa ibe:iilensi eziphantsi kokugqwetheka(ezinokunciphisa impembelelo yokuphazamiseka komfanekiso kwaye zifanelekile kwiimeko zokusetyenziswa ezifuna umlinganiselo ochanekileyo), iilensi ezichasene nokungcangcazela (ezifanelekileyo kwiindawo zoshishino ezineentshukumo ezinkulu), njl.
