Amalensi ezimboni asetshenziswa kabanzi emkhakheni wezimboni futhi angenye yezinhlobo zamalensi ezivamile. Izinhlobo ezahlukene zamalensi ezimboni zingakhethwa ngokuya ngezidingo ezahlukene kanye nezimo zokusetshenziswa.

Indlela yokuhlukanisa amalensi ezimboni?

Amalensi ezimbonizingahlukaniswa ngezinhlobo ezahlukene ngokwezindinganiso ezahlukene zokuhlela. Izindlela ezivamile zokuhlela yilezi ezilandelayo:

Ukuhlukaniswa okusekelwe esakhiweni selensi. 

Ngokwesakhiwo selensi yelensi, amalensi ezimboni angahlukaniswa ngamalensi angawodwa (njengamalensi aqondile, amalensi aqondile), amalensi ahlanganisiwe (njengamalensi e-biconvex, amalensi e-biconcave), amaqembu amalensi ahlanganisiwe, njll.

Kuhlukaniswe ngokwebanga eliqondile.

Kuhlukaniswe ngokwesilinganiso sobude be-lens,amalensi ezimbonifaka amalensi ane-wide angle, amalensi ajwayelekile, amalensi e-telephoto, njll.

Kuhlukaniswe ngokwezindawo zokufaka isicelo.

Njengoba ihlukaniswe ngokwezinkambu zokusetshenziswa zelensi, amalensi ezimboni angahlukaniswa ngamalensi okubona komshini, amalensi okulinganisa ezimboni, amalensi okuthwebula izithombe zezokwelapha, amalensi e-microscope, njll.

Kuhlukaniswe ngokwezinhlobo zesixhumi esibonakalayo.

Njengoba ihlukaniswe ngohlobo lwesixhumi esibonakalayo selensi, amalensi ezimboni afaka phakathi i-C-mount, i-CS-mount, i-F-mount, i-M12-mount nezinye izinhlobo.

Ukuhlukaniswa okusekelwe kumapharamitha okukhanya.

Amalensi ahlukaniswa ngokwemingcele yawo yokukhanya, okuhlanganisa ubude bokugxila, ukuvuleka, insimu yokubuka, ukuhlanekezela, i-astigmatism, isixazululo, njll.

Ilensi yezimboni

Uyini umehluko phakathi kwamalensi ezimboni namalensi ajwayelekile?

Ngokushintsha kwesidingo kanye nokuthuthuka kobuchwepheshe, umehluko ezicini zokusebenza phakathiamalensi ezimbonikanye namalensi ajwayelekile abathengi ayanyamalala kancane kancane, kanti amanye amalensi ezimboni namalensi ajwayelekile nawo angasetshenziswa ngokushintshana. Ngokuvamile, umehluko phakathi kwamalensi ezimboni namalensi ajwayelekile umi kanje:

Izakhiwo ezahlukene zokukhanya

Uma kuqhathaniswa namalensi ajwayelekile, amalensi ezimboni anezidingo eziphakeme zekhwalithi yesithombe nokunemba. Ngokuvamile anokuhlanekezela okuphansi, ukuphambuka kwe-chromatic kanye nokuncipha kokukhanya, okuqinisekisa ukunemba nokuthembeka kwesithombe. Amalensi ajwayelekile angase abe nokuyekethisa okuthile kwezinye izinhlaka, ikakhulukazi ephishekela imiphumela engcono yobuciko kanye nolwazi lomsebenzisi.

Izinjongo ezahlukene zokuklama

Amalensi ezimbonizenzelwe kakhulu izinhlelo zokusebenza zezimboni ezifana nombono womshini, ukulawula okuzenzakalelayo, ukulinganisa kanye nokuhlaziya. Zenzelwe ukuhlangabezana nezidingo zokunemba okuphezulu, ukulungiswa okuphezulu kanye nokuzinza. Amalensi ajwayelekile aklanyelwe kakhulu izinhlelo zokusebenza zezithombe, amafilimu kanye nethelevishini, futhi anaka kakhulu ukusebenza kwezithombe kanye nemiphumela yobuciko.

Izindlela ezahlukene zokugxila

Amalensi ajwayelekile ngokuvamile anomsebenzi we-autofocus, ongalungisa ngokuzenzakalelayo ukugxila ngokuya ngesimo kanye nesihloko. Amalensi ezimboni ngokuvamile asebenzisa ukugxila ngesandla, futhi abasebenzisi kudingeka balungise ubude bokugxila kanye nokugxila ngesandla ukuze bazivumelanise nezimo nezidingo ezahlukene zokusetshenziswa kwezimboni.

Umehluko ekuqineni nasekuzivumelaniseni nezimo

Amalensi ezimbonikudingeka zikwazi ukumelana nezimo zezimboni ezinzima, njengamazinga okushisa aphezulu naphansi, umswakama kanye nokudlidliza, ngakho-ke ngokuvamile zidinga ukuqina okuqinile kanye nokuzivumelanisa nezimo. Uma kuqhathaniswa, amalensi ajwayelekile aklanyelwe ukuba alula, athwaleke futhi kube lula ukuwaphatha, okwenza kube lula ukuwasebenzisa ezindaweni ezivamile.
