Iyini ilensi yokubona ngomshini?
A ilensi yokubona komshiniiyingxenye ebalulekile ohlelweni lokubona komshini, oluvame ukusetshenziswa ekukhiqizeni, kumarobhothi, kanye nasezinhlelweni zokuhlola zezimboni. Ilensi isiza ekuthwebuleni izithombe, ihumushe amaza okukhanya abe yifomethi yedijithali uhlelo olungayiqonda futhi luyicubungule. Ikhwalithi nezici zelensi kungathinta kakhulu ikhono lesistimu lokubona, ukukala, noma ukuhlola izinto ngokunembile.
Ziyini izinhlobo zamalensi okubona komshini?
Ezinye izinhlobo ezivamile zamalensi ombono womshini zifaka:
1. Amalensi aqondile aqondile: La malensi anobude obuqondile obuqondile futhi ahlinzeka ngokukhulisa okuqhubekayo kokuthwebula izithombe zezinto ezikude nelensi. Afanele ukusetshenziswa lapho ibanga lokusebenza nosayizi wento kuhlala kungaguquki.
2. Amalensi okusondeza:Amalensi e-Zoom anikeza ubude obulungisekayo bokugxila, okuvumela abasebenzisi ukuthi bashintshe insimu yokubuka kanye nokukhulisa njengoba kudingeka. Anikeza ukuguquguquka ekuthwebuleni izithombe zezinto ezikude ezahlukene.
3. Amalensi e-Telecentric:Amalensi e-Telecentric aklanyelwe ukukhiqiza imisebe yokukhanya ehambisanayo, okusho ukuthi imisebe eyinhloko iqonde ngqo ku-sensor yesithombe. Lesi sici siphumela ekulinganisweni okunembile nokungaguquguquki kobukhulu bezinto, okwenza zifanelekele ukusetshenziswa kokulinganisa okunembile.
4.Amalensi ane-engeli ebanzi: Amalensi ane-engeli ebanzi anobude obufushane bokugxila kanye nensimu ebanzi yokubuka, okwenza abe usizo ezinhlelweni zokusebenza ezidinga ukuthwebula izithombe zezindawo ezinkulu noma izigcawu.
Uma ukhetha ilensi yokubona komshini, izici okufanele uzicabangele zifaka phakathi ibanga lokusebenza elifiswayo, insimu yokubuka, isixazululo, ikhwalithi yesithombe, ukuhambisana kokukhwezwa kwelensi, kanye nezidingo ezithile zohlelo lokusebenza.
Yiziphi izici zelensi yokubona komshinis?
Izici zamalensi okubona ngomshini zingahluka kuye ngomkhiqizi welensi kanye nomodeli othile. Kodwa-ke, ezinye izici ezivamile zamalensi okubona ngomshini zifaka:
1. Ama-optics anesinqumo esiphezulu:Amalensi okubona komshini aklanyelwe ukuhlinzeka ngezithombe ezicacile nezibukhali, ngokuvamile afanelana namakhono okuxazulula amakhamera anezinqumo eziphezulu.
2. Ukuhlanekezela okuphansi: Amalensi anokuhlanekezela okuphansi aqinisekisa ukuthi isithombe esithathwe sinembile futhi asihlanekezelwanga, ikakhulukazi ezinhlelweni zokusebenza ezidinga ukulinganiswa noma ukuhlolwa okunembile.
3. Ububanzi be-spectral:Amanye amalensi okubona ngomshini aklanyelwe ukusebenza ngamaza okukhanya ahlukene, okuvumela izinhlelo zokusebenza ezisebenzisa ukukhanya okubonakalayo, ukukhanya kwe-ultraviolet (UV), ukukhanya kwe-infrared (IR), noma izithombe ze-multispectral.
4. Ukuguquguquka nokuguquguquka: Amalensi athile, njenge-zoom lens, anikeza ubude obulungisekayo bokugxila kanye nensimu yokubuka, okunikeza ikhono lokuthwebula izithombe ekukhulisweni okuhlukahlukene kanye namabanga ezinto.
5. Ukugxila kwe-Telecentricity: Amalensi e-telecentric akhiqiza imisebe yokukhanya ehambisanayo, okuholela ekukhulisweni okuqhubekayo kanye nokulinganiswa okunembile kobukhulu bento, kungakhathaliseki ukuthi ibanga lento lingakanani.
6. Ukulungiswa kokugxila: Amalensi okubona komshini avame ukunikeza ukulungiswa kokugxila ngesandla noma ngenjini, okuvumela abasebenzisi ukuthi bathuthukise ubukhali besithombe kumabanga ahlukene ezinto.
7. Idizayini encane futhi elula: Amalensi okubona ngomshini ngokuvamile aklanyelwe ukuba mancane futhi abe lula, okwenza afaneleke ukuhlanganiswa nezinhlelo zokubona nokunciphisa umthelela ojwayelekile.
8. Ukuhambisana kwe-Mount: Amalensi okubona komshini ayatholakala ngezikhonkwane ezahlukene zamalensi (njenge-C-mount, i-F-mount, i-M42, njll.), okuqinisekisa ukuhambisana nezinhlobo eziningi zamakhamera noma izixhumi ezisebenzisanayo.
9. Ukuqina kwemvelo: Amanye amalensi okubona komshini aklanyelwe ukumelana nezimo zezimboni ezinzima, ezinezici ezifana nezindlu eziqinile, ukuvikela uthuli, kanye nokumelana nokudlidliza noma ukushintsha kwezinga lokushisa.
10. Ukusebenza kahle kwezindleko: Amalensi okubona ngomshini avame ukuhlose ukuhlinzeka ngezixazululo ezingabizi kakhulu zezinhlelo zokusebenza zokuthwebula izithombe, okuthola ibhalansi phakathi kokusebenza kanye nokungabizi.
Kubalulekile ukuhlola izidingo ezithile zohlelo lwakho lokusebenza lokubona komshini bese ukhetha izici zelensi ezifanelana kahle nezidingo zakho.
