Ingabe amalensi wezimboni angasetshenziswa njengamalensi we-SLR? Yimaphi amapharamitha okufanele siwanake lapho ukhetha amalensi wezimboni?

1,Ingabe amalensi wezimboni angasetshenziswa njengamalensi we-SLR?

Imiklamo nokusetshenziswa kweamalensi wezimboninama-slr lens ahlukile. Yize bobabili amalensi, indlela abasebenza ngayo kanye nezimo abasetshenziswa kuyo bayohluka. Uma usendaweni yokukhiqiza yezimboni, kunconywa ukusebenzisa ama-lens akhethekile wezimboni; Uma wenza umsebenzi wezithombe, kunconyelwa ukusebenzisa ama-lens wekhamera ochwepheshe.

Ama-lens wezimboni adalwe ngokunemba ngokunemba, ukuqina, kanye nokuqina, ngokuyinhloko ukufeza izidingo zokukhiqiza nezinye izinhlelo zokusebenza, njengokusetshenziswa okuthile kwi-automation, ukubhekwa, ucwaningo lwezokwelapha, nokuningi.

Idizayini ye-SLR Lens ikakhulukazi idinga ukucubungula ukusebenza kwe-Optical, isisho sobuciko kanye nesipiliyoni somsebenzisi, njll., Ukuze sihlangabezane nezidingo zabathwebuli bezithombe zekhwalithi yesithombe nokusebenza okusha.

Yize kutholakala ubuchwepheshe ukufaka ilensi yezimboni kwikhamera ye-SLR (ihlinzeke ngemininingwane ebonakalayo), imiphumela yokudubula kungenzeka ingabi kahle. Ama-lens wezimboni angeke anikeze ikhwalithi yesithombe esihle kakhulu noma ukusebenza, futhi kungenzeka angasebenzi ngokuvezwa kwekhamera yakho noma uhlelo lokufakelwa kwekhamera.

Ikhamera ye-SLR

Kwezinye izidingo zezithombe ezikhethekile, ezinjengezithombe ezisondele kakhulu ze-microscopic, kungenzeka ukufakaamalensi wezimboniKumakhamera we-SLR, kepha lokhu kuvame ukudinga imishini yokusekela ochwepheshe nolwazi lobuchwepheshe ukusekela ukuphothulwa.

2,Yimaphi amapharamitha okufanele siwanake lapho ukhetha amalensi wezimboni?

Lapho ukhetha ilensi yezimboni, udinga ukubheka amapharamitha ahlukahlukene. Amapharamitha alandelayo ngokuvamile agxile:

Ubude obugxile:

Ubude obugxile bunquma inkambu yokubuka nokukhulisa kwelensi. Ubude obubheke isikhathi eside buhlinzeka ngokubuka okubushele nokukhulisa, ngenkathi ubude obufushane bokugxila bunikeza insimu ebanzi yokubuka. Ngokuvamile kunconywa ukukhetha ubude obugxile obufanele ngokuya ngezidingo zezimo ezithile zohlelo lokusebenza.

Umphetho:

I-aperture inquma inani lokukhanya okudluliselwa ngamalensi futhi lithinta ukucaca nokujula kwesithombe. I-aperture ebanzi ivumela ukuvezwa okungcono nekhwalithi yesithombe ezimeni eziphansi. Uma ukukhanyisa kwesimo odubulayo kubuthakathaka, kunconywa ukukhetha ilensi ngesithambisi esikhudlwana.

Isixazululo:

Ukulungiswa kwe-lens kunquma imininingwane yesithombe kungathatha, nezinqumo eziphakeme zokuhlinzeka ngezithombe ezicacile, ezinemininingwane eminingi. Uma unezidingo eziphakeme zokucaciswa kwezithombe ezithunjiwe, kunconyelwa ukukhetha i-lens yesinqumo esiphakeme.

Ilensi yezimboni

Inkambu yokubuka:

Inkambu yokubuka ibhekisela ezinhlolweni zezinto amalensi angawamboza, avame ukuvezwa ngama-engeli avundlile nawomile. Ukukhetha inkambu efanelekile yokubuka kuqinisekisa ukuthi i-lens ingabamba ibanga lesithombe elifunekayo.

Uhlobo lwe-Interface:

Uhlobo lwe-interface lwelensi kufanele lufane nekhamera noma imishini esetshenzisiwe. -JwayelekileIlensi yezimboniIzinhlobo ezibonakalayo zifaka i-C-Mount, CS-Mount, F-Mount, njll.

Ukuhlanekezela:

Ukuhlanekezela kubhekiswa ekuguqukeni okwenziwa yilensi lapho kunezithombe zento entweni ezithobekayo. Ngokuvamile, amalensi wezimboni anezidingo eziphakeme zokuhlanekezela. Ukukhetha ilensi ngokuhlanekezela okuphansi kungaqinisekisa ukunemba nokunemba kwesithombe.

Ikhwalithi yelensi:

Ikhwalithi yelensi ithinta ngqo ukucaciswa kanye nokukhiqizwa kombala kwesithombe. Lapho ukhetha ilensi, udinga ukuqinisekisa ukuthi ukhetha uhlobo lwelensi ephezulu nemodeli.

Ezinye izidingo ezikhethekile: Lapho ukhetha ama-lens wezimboni, futhi udinga ukubheka ukuthi imvelo lapho isetshenziswa khona inezidingo ezikhethekile zinezidingo ezikhethekile zelensi, njengokungavuthisi, nothuli okuphezulu, kanye nokushisa okuphezulu.

Imicabango yokugcina:

UChuangan wenze ukwakheka kokuqala nokukhiqizwa kwamalensi wezimboni, asetshenziswa kuzo zonke izici zezicelo zezimboni. Uma unentshisekelo noma unezidingo zeamalensi wezimboni, sicela uxhumane nathi ngokushesha okukhulu.
