Amalensi ezimboni asetshenziswa kakhulu emkhakheni wezimboni futhi angenye yezinhlobo zamalensi ezivamile.Izinhlobo ezahlukene zamalensi ezimboni zingakhethwa ngokuya ngezidingo ezahlukene kanye nezimo zohlelo lokusebenza.

Ungawahlukanisa kanjani amalensi ezimboni?

Amalensi ezimbonizingahlukaniswa zibe izinhlobo ezahlukene ngokwamazinga ahlukene okuhlukanisa.Izindlela ezijwayelekile zokuhlukanisa zimi kanje:

Ukuhlelwa okusekelwe esakhiweni selensi. 

Ngokwesakhiwo selensi yelensi, amalensi ezimboni angahlukaniswa abe amalensi angawodwa (njengamalensi aconvex, amalensi aconcave), amalensi ayinhlanganisela (njengamalensi e-biconvex, amalensi e-biconcave), amaqembu amalensi ayinhlanganisela, njll.

Kuhlukaniswa ngokobude bokugxila.

Ihlukaniswa ngokuya ngobude bokugxila belensi,amalensi ezimbonikufaka phakathi amalensi e-engeli ebanzi, amalensi ajwayelekile, amalensi e-telephoto, njll.

Ihlukaniswe ngokwezindawo zokufaka izicelo.

Ahlukaniswa ngokwemikhakha yokusetshenziswa kwamalensi, amalensi ezimboni angahlukaniswa abe amalensi omshini, amalensi okulinganisa embonini, amalensi ezithombe zezokwelapha, amalensi e-microscope, njll.

Ihlukaniswe ngokohlobo lwesixhumi esibonakalayo.

Ahlukaniswa ngokohlobo lwesixhumi esibonakalayo se-lens, amalensi ezimboni afaka i-C-mount, i-CS-mount, i-F-mount, i-M12-mount nezinye izinhlobo.

Ukuhlukaniswa ngokusekelwe kumapharamitha abonakalayo.

Amalensi ahlukaniswa ngokwemingcele yawo yokubona, okuhlanganisa ubude bokugxila, indawo yokuvula, indawo yokubuka, ukuhlanekezela, i-astigmatism, ukulungiswa, njll.

Ilensi yezimboni

Uyini umehluko phakathi kwamalensi ezimboni kanye namalensi ajwayelekile?

Ngezinguquko ezidingekayo kanye nokuthuthuka kobuchwepheshe, umehluko ezicini zokusebenza phakathiamalensi ezimboninamalensi omthengi ajwayelekile ayashabalala kancane kancane, kanti amanye amalensi ezimboni kanye namalensi ajwayelekile nawo angasetshenziswa ngokushintshana.Ngokuvamile, umehluko phakathi kwamalensi ezimboni kanye namalensi ajwayelekile umi kanje:

Izakhiwo ezihlukile ze-optical

Uma kuqhathaniswa namalensi avamile, amalensi ezimboni anezidingo eziphakeme zekhwalithi yesithombe nokunemba.Ngokuvamile zinokuhlanekezela okuphansi, ukujika kwe-chromatic kanye nokunciphisa ukukhanya, okuqinisekisa ukunemba kwesithombe nokwethembeka.Amalensi avamile angase abe nokuyekethisa okuthile kweminye imingcele, ikakhulukazi aphishekele imiphumela yobuciko engcono nolwazi lomsebenzisi.

Izinhloso ezihlukene zokuklama

Amalensi ezimboningokuyinhloko yakhelwe izinhlelo zokusebenza zezimboni ezifana nombono womshini, ukulawula okuzenzakalelayo, ukulinganisa nokuhlaziya.Zenzelwe ukuhlangabezana nokunemba okuphezulu, ukulungiswa okuphezulu kanye nezidingo zokuzinza.Amalensi avamile aklanyelwe ikakhulukazi ukuthwebula izithombe, ifilimu nezinhlelo zokusebenza zethelevishini, futhi anaka kakhulu ukusebenza kwesithombe nemiphumela yobuciko.

Izindlela ezihlukene zokugxila

Amalensi avamile ngokuvamile anomsebenzi we-autofocus, ongalungisa ngokuzenzakalelayo ukugxila ngokwendawo kanye nesihloko.Amalensi ezimboni ngokuvamile asebenzisa ukugxila okwenziwa ngesandla, futhi abasebenzisi badinga ukulungisa mathupha ubude bokugxila futhi bagxile ukuze bavumelane nezimo nezidingo zohlelo lokusebenza lwemboni ezahlukene.

Umehluko wokuqina nokuvumelana nezimo

Amalensi ezimbonizidinga ukumelana nezindawo zezimboni ezinokhahlo, njengamazinga okushisa aphezulu naphansi, umswakama nokudlidliza, ngakho ngokuvamile zidinga ukuba nokuqina okuqinile nokuzivumelanisa nezimo.Uma kuqhathaniswa, amalensi avamile aklanyelwe ukuba angasindi, aphatheke kalula futhi athwale kalula, awenze kube lula ukuwasebenzisa ezindaweni ezivamile.
