A ilensi yokugxila egxilileilensi enobude obuqondile obungaguquki, ngokuvamile enombobo omkhulu kanye nekhwalithi ephezulu yokukhanya. Ngakho-ke, ungayikhetha kanjani ilensi yokugxila engaguquki? Yiziphi izinto okufanele uzicabangele lapho ukhetha ilensi yokugxila engaguquki?
Uma ukhetha ilensi yokugxila engaguquki, izici ezilandelayo zidinga ukucatshangelwa ngokuphelele:
Fubude bamehlo
Ubude be-focal bungenye yezinto zokuqala okufanele uzicabangele lapho ukhetha ilensi yokugxila egxilile. Ubude be-focal bunquma insimu yokubuka kwelensi, kanti amalensi okugxila agxilile anobude obuhlukene be-focal afanelekela ukuthwebula izigcawu nezindikimba ezahlukene. Ubude obujwayelekile be-focal buhlanganisa u-50mm, 85mm, 35mm, njll.
Ngokuvamile, ubude obungama-50mm buyi-focal length eseduze kakhulu nombono weso lomuntu, bufanelekela izithombe zokudubula kanye nezigcawu zokuphila kwansuku zonke; ubude obungama-85mm nangaphezulu bufanelekela izithombe zocingo kanye nezithombe; ubude obungama-focal obungaphansi kwama-35mm bufanelekela ukuthwebula izindawo ezibanzi kanye nezithombe zemvelo.

Imbobo
Ubukhulu bomgodi wokukhanya buthinta inani lokukhanya okungena kulensi kanye nekhono layo lokulawula ukujula kwensimu.
Ngokuvamile,ilensi yokugxila okugxililenge-aperture enkulu (njenge-F1.4, F1.8) ingathatha izithombe ezicacile ezindaweni ezinokukhanya okuphansi futhi ikhiqize umphumela ongcono wokufiphaza ingemuva, ofanele izithombe zobulili kanye nezithombe eziseduze; ilensi ene-aperture encane (njenge-F2.8, F4) izinzile kakhulu ekulawuleni okujulile kwensimu kanye nokusebenza kokukhanyisa emuva, futhi ifanele ukuthwebula izindawo nezakhiwo ezine-aperture ejulile yensimu.
Ikhwalithi yelensi
Ngaphezu kokugxila ebudeni be-focal kanye ne-aperture, udinga futhi ukucabangela ikhwalithi yelensi lapho ukhetha ilensi egxilile. Ikhwalithi yelensi ihlanganisa izici ezifana nekhwalithi yengilazi yelensi, ukumbozwa kwelensi, kanye ne-focus motor.
Amalensi engilazi asezingeni eliphezulu kanye nomklamo welensi kunganikeza ikhwalithi ephezulu yesithombe kanye nokukhiqizwa kabusha kombala, kuyilapho kuvimbela ukwenzeka kwezehlakalo ezibonakalayo njengokusabalala kwelensi.
Ikhwalithi yelensi ithinta ikhwalithi yesithombe
Isisindo kanye nomthamo
Amalensi okugxila aqinile ngokuvamile alula kunelensi ye-zoom, kodwa futhi anesisindo nomthamo othile. Isisindo selensi sizothinta ngqo ulwazi lomsebenzisi.
Izinto ezisezingeni eliphezulu kanye nesisindo esimaphakathi kungathuthukisa ukuqina kanye nokuphatheka kalula kwelensi. Lokhu kunganqunywa ngokusekelwe emikhubeni yakho yokusebenzisa kanye nezidingo zakho zokudubula.
Intengo
Uhla lwamananiamalensi okugxila okugxilileibanzi, kusukela ezingeni lokuqala kuya ezingeni lochwepheshe. Amanani amalensi emikhiqizo ehlukene, amamodeli kanye nokucaciswa kuyahlukahluka kakhulu, ngokuvamile asukela kumakhulu ambalwa kuya ezinkulungwaneni eziningana zama-yuan. Udinga ukukhetha elikufanele ngokwesabelomali sakho.
Khetha ilensi ekufanele ngokwesabelomali sakho
Ngaphezu kwalokho, lapho ukhetha ilensi egxilile, udinga futhi ukucabangela uhlobo lwekhamera oyisebenzisayo kanye nesixhumi esibonakalayo selensi ukuqinisekisa ukuthi ilensi iyahambisana nekhamera.
Imicabango Yokugcina:
Uma unesifiso sokuthenga izinhlobo ezahlukene zamalensi okuqapha, ukuskena, ama-drones, ikhaya elihlakaniphile, noma olunye uhlobo lokusetshenziswa, sinalokho okudingayo. Xhumana nathi namuhla ukuze ufunde kabanzi ngamalensi ethu nezinye izesekeli.
