Ngaba indawo ebonakalayo yesibane sentloko ingcono xa unelensi okanye ikomityi yokukhanya?

Isibane sentloko sokuntywilayenye yezixhobo ezisetyenziswa kakhulu kwimidlalo yokuntywila, enokubonelela ngomthombo wokukhanya, ukuze abantywila bakwazi ukubona ngokucacileyo imeko-bume engqongileyo elwandle olunzulu. Icandelo elibonakalayo lesibane sentloko sokuntywila liyinxalenye ebalulekileyo yokumisela isiphumo saso sokukhanya, apho ilensi kunye nendebe yokukhanya zizinto ezimbini eziqhelekileyo ze-optical. Ngoko ke, yintoni umahluko phakathi kokusetyenziswa kweelensi kunye neekomityi zokukhanya kwizibane zentloko zokuntywila?

Okokuqala, makhe sijonge ingcamango esisiseko yelensi kunye nekomityi yokukhanya. Ilensi yinto ebonakalayo, "ekwaziyo ukugxila ekukhanyeni. Iyakwazi ukubonakalisa okanye ukwahlukanisa ukukhanya, ngaloo ndlela itshintsha indlela kunye nokusasazwa kokukhanya ngamandla." Ikomityi yokukhanya sisibonisi se-optical kwaye sigxile kwindawo ethile ukuze kwandiswe ukukhanya kunye nokugxila ekukhanyeni.

In Izibane zentloko ze-LED ezinokutshajwa kwakhona, ilensi kunye nekomityi yokukhanya zisebenza ngokwahlukileyo. Ilensi isetyenziselwa kakhulu ukulungisa indlela yokusasazeka kunye nokusasazwa kokukhanya ngamandla, ukuze ukukhanya kukhanyise ngcono umphambili womntywili. Ilensi ingayilwa ngokweemfuno, umzekelo, ilensi engqukuva ingagxila ukukhanya kuluhlu oluncinci, ngaloo ndlela iphucula ukukhanya kunye nefuthe lokugxila kokukhanya; Iilensi ezingqukuva zingasasaza ukukhanya, zivumele ukukhanya kukhanyise indawo engqongileyo ngokubanzi. Ukukhethwa kunye noyilo lwelensi kufuneka kuthathelwe ingqalelo iimfuno zabantywili ukuzeisibane sentloko esikhokelwayo sangaphandlekunye neempawu zendawo yokuntywila.

Ikomityi yokukhanya isetyenziselwa kakhulu ukuphucula ukukhanya kunye nefuthe lokugxila kokukhanya. Ikomityi yokukhanya inokubonakalisa kwaye ijolise ukukhanya kwindawo ethile, okwenza ukukhanya kube kugxile ngakumbi kwaye kuqine. Uyilo kunye nokukhethwa kwezinto zekomityi yokukhanya kunempembelelo ebalulekileyo kwisiphumo sokugxila kokukhanya. Ngokubanzi, okukhona imilo yekomityi yokukhanya inzulu, kokukhona isiphumo sokugxila kokukhanya singcono, kodwa kwangaxeshanye, kuya kukhokelela kuluhlu oluncinci lokukhanya. Ke ngoko, ukhetho lweekomityi zokukhanya kufuneka lulinganiswe ngokweemfuno zabantywila kwii-headlamps zokuntywila kunye neempawu zendawo yokuntywila.

Ilensi isetyenziselwa kakhulu ukulungisa indlela yokusasazeka kunye nokusasazwa kokukhanya ngamandla, ukuze ukukhanya kukhanyise ngcono umphambili womntywili. Ikomityi yokukhanya isetyenziselwa kakhulu ukuphucula ukukhanya kunye nefuthe lokugxila kokukhanya, okwenza ukukhanya kube kugxile ngakumbi kwaye kuqine. Ukukhetha kunye noyilo lwelensi kunye nekomityi yokukhanya kufuneka kulinganiswe neemfuno zomntu osebenzisa le khamera.Isibane sentloko esitshajwayo se-USBkunye neempawu zendawo yokuntywila.

Ukongeza, ilensi kunye nekomityi yokukhanya nazo zinomahluko othile kwisiphumo sokukhanyaizibane zentloko zesensor ezinokutshajwa kwakhona. Isibane sentloko sokuntywila selensi singatshintsha isiphumo sokugxila kokukhanya ngokulungelelanisa ubude kunye nemilo yefocal, ukuze ukukhanya kwesibane sentloko sokuntywila kukhanyise ngcono umphambili womntywili. Isibane sentloko sokuntywila sendebe yokukhanya siphucula kakhulu ukukhanya kunye nesiphumo sokugxila kokukhanya kwesibane sentloko sokuntywila ngokubonakalisa ukukhanya kunye nokukugxila kwindawo ethile. Ke ngoko, isibane sentloko sokuntywila selensi kunye nesibane sentloko sokuntywila sendebe yokukhanya zineempawu ezahlukeneyo kunye neenzuzo kwisiphumo sokukhanya.

Ngamafutshane, kukho umahluko othile ekusebenziseni iilensi kunye neekomityi zokukhanya kwizibane zentloko zokuntywila. Isibane sentloko sokuntywila seelensi sisetyenziselwa kakhulu ukulungisa indlela yokusasazeka kunye nokusasazwa kokukhanya ngamandla, ukuze ukukhanya kwesibane sentloko sokuntywila kukhanyise ngcono umphambili womntywili; Ikomityi yokukhanyaisibane sentloko esingangeni manziIsetyenziswa kakhulu ukuphucula ukukhanya kunye nefuthe lokugxila ekukhanyeni. Ukukhethwa kunye noyilo lwezibane ze-lens kunye ne-light cup kufuneka zilinganiswe ngokweemfuno zomntywili kunye neempawu zendawo yokuntywila. Nokuba zizibane ze-lens diving okanye izibane ze-light cup diving, zizinto ezibonakalayo ezibalulekileyo kwizibane ze-diving, kwaye ukusetyenziswa kwazo ngokufanelekileyo kunokuphucula ukhuseleko kunye namava okuntywila kwabantywili.
