Ilensi yombono womshiniiyilensi eyenzelwe ukusetshenziswa ezinhlelweni zokubona komshini, ezaziwa nangokuthi amalensi ekhamera yezimboni. Izinhlelo zokubona ngomshini ngokuvamile zihlanganisa amakhamera ezimboni, amalensi, imithombo yokukhanya, nesofthiwe yokucubungula izithombe.
Asetshenziselwa ukuqoqa ngokuzenzakalela, ukucubungula, nokuhlaziya izithombe ukuze wahlulele ngokuzenzakalelayo ikhwalithi yezingcezu zokusebenza noma ukuqedela izilinganiso zokuma ezinembayo ngaphandle kokuxhumana. Zivame ukusetshenziselwa ukulinganisa okunembe Kakhulu, ukuhlanganisa okuzenzakalelayo, ukuhlola okungabhubhisi, ukutholwa kokukhubazeka, ukuzulazula kwerobhothi nezinye izinkambu eziningi.
1.Yini okufanele uyicabangele lapho ukhetha amalensi ombono womshini?
Lapho ukhethaumshini wokubona lens, udinga ukucabangela izici ezihlukahlukene ukuze uthole ilensi ekufanele kakhulu. Izici ezilandelayo ziyizinto ezicatshangelwayo ezivamile:
Inkambu yokubuka (i-FOV) nebanga lokusebenza (WD).
Inkambu yokubuka nebanga lokusebenza inquma ukuthi inkulu kangakanani into ongayibona kanye nebanga ukusuka ku-lens ukuya entweni.
Uhlobo lwekhamera oluhambisanayo nosayizi wenzwa.
Ilensi oyikhethayo kufanele ifane nesixhumi esibonakalayo sekhamera yakho, futhi ukugoba kwesithombe selensi kufanele kube kukhulu noma kulingane nebanga le-diagonal lenzwa.
Kudluliselwe ugongolo isigameko ugongolo.
Kuyadingeka ukucacisa ukuthi uhlelo lwakho lokusebenza ludinga ukuhlanekezela okuphansi, ukulungiswa okuphezulu, ukujula okukhulu noma ukulungiswa kwelensi yokuvula enkulu.
Usayizi wento namakhono wokuxazulula.
Ukuthi into ofuna ukuyibona inkulu kangakanani nokuthi ukulungiswa kudingakala kahle kangakanani, okunquma ukuthi inkulu kangakanani inkambu yokubuka nokuthi udinga amaphikiseli amangaki ikhamera.
Eizimo zemvelo.
Uma unezidingo ezikhethekile zendawo ezungezile, ezifana ne-shockproof, uthuli noma ukungangeni kwamanzi, udinga ukukhetha ilensi engahlangabezana nalezi zidingo.
Isabelomali sezindleko.
Hlobo luni lwezindleko ongazikhokhela luzothinta uhlobo lwelensi kanye nemodeli oyikhethayo ekugcineni.

2.Indlela yokuhlukanisa yamalensi ombono womshini
Kunezici eziningi okufanele zicatshangelwe lapho ukhetha amalensi.Amalensi okubona omshiniingabuye ihlukaniswe ngezinhlobo ezahlukene ngokuya ngamazinga ahlukene:
Ngokuya ngohlobo lobude bokugxila, ingahlukaniswa ibe:
Ilensi yokugxila egxilile (ubude bokugxila bugxilile futhi abukwazi ukulungiswa), ilensi yokusondeza (ubude bokugxila buyalungiseka futhi ukusebenza kuyavumelana nezimo).
Ngokuya ngohlobo lwembobo, ingahlukaniswa ibe:
Ilensi yokuvula ngesandla (imbobo idinga ukulungiswa ngesandla), ilensi yokuvula okuzenzakalelayo (i-lens ingalungisa ngokuzenzakalelayo indawo yokungena ngokuya ngokukhanya okuzungezile).
Ngokwezidingo zokulungiswa kwesithombe, ingahlukaniswa ibe:
Amalensi okulungiswa okujwayelekile (afanele izidingo zesithombe ezivamile ezifana nokuqapha okuvamile nokuhlolwa kwekhwalithi), amalensi anokulungiswa okuphezulu (afanele ukutholwa okunembayo, ukuthwebula isithombe ngesivinini esikhulu nezinye izinhlelo zokusebenza ezinezidingo zokulungiswa okuphezulu).
Ngokuya ngosayizi wezinzwa, ingahlukaniswa ibe:
Amalensi efomethi yenzwa encane (afanele izinzwa ezincane ezifana no-1/4″, 1/3″, 1/2″, njll.), amalensi efomethi yenzwa emaphakathi (afanele izinzwa ezinosayizi omaphakathi njengo-2/3″, 1″ , njll. inzwa), amalensi efomethi yenzwa enkulu (yezinzwa zohlaka olugcwele ezingu-35mm noma ezinkulu).
Ngokuya ngemodi yokuthwebula, ingahlukaniswa ibe:
Ilensi yokuthwebula ye-Monochrome (ingathwebula kuphela izithombe ezimnyama nezimhlophe), ilensi yokuthwebula umbala (ingathwebula izithombe ezinemibala).
Ngokwezidingo ezikhethekile zokusebenza, zingahlukaniswa zibe:ama-lens aphansi(okunganciphisa umthelela wokuhlanekezela kukhwalithi yesithombe futhi zifanele izimo zohlelo lokusebenza ezidinga ukulinganisa okunembile), amalensi alwa nokudlidliza (afanele izindawo zezimboni ezinokudlidliza okukhulu), njll.
