I-DSLR, noma ikhamera ye-digital lens reflex ikhamera yikhamera yedijithali ehamba phambili enikeza ikhwalithi yezinga eliphakeme eliphezulu, amazinga okusebenza, kanye nezinketho zokulawula amabhuku, ngokuvamile kangcono kakhulu kunalokho ongayithola ngekhamera lensimbi ehleliwe kwi-smartphone. Lolu hlobo lwekhamera lisebenzisa amalensi angashintshashintshayo, ngenkathi ikhamera ye-lens egxilile ine-lens eyakhiwa emzimbeni wekhamera futhi umthwebuli wezithombe akanakushintsha.
Nakuba abathwebuli bezithombe cishe cishe noma yikuphi izinga lokuhlangenwe nakho bangathenga futhi basebenzise ikhamera ye-DSLR , lezi zinhlobo zamakhamera zingcono kubathwebuli bezithombe abanokuhlangenwe nakho okunye nge-digital photography . Ngenxa yokuthi amakhamera we-DSLR angabiza noma yikuphi kusuka kuma-dollar angamakhulu amaningana kuya kuma-dollar ayizinkulungwane ezimbalwa, ajwayele ukulungele abathwebuli bezithombe abanokuhlangenwe nakho okwanele ukusebenzisa izici zabo zokugcina eziphezulu.
I-DSLR Amakhamera Vs. AmaKhamera angenalutho
Amakhamera we-DSLR akuyona kuphela uhlobo lwekhamera lens engashintsha noma kunjalo. Olunye uhlobo lwekhamera ye-lens eguquguqukayo, ebizwa ngokuthi ikhamera elingenasipiliyoni, linomklamo ohlukile ongaphakathi kune-DSLR.
Idizayini yangaphakathi yekhamera ye-DSLR iqukethe isibuko esivimbela ukukhanya ekuhambeni kwe-lens nokushaya inzwa yesithombe. (I-sensor yesithombe yi-chip sensitive sensitive ngaphakathi ikhamera yedijithali elinganisa ukukhanya endaweni, okuyisisekelo sokwakha isithombe se-digital.) Uma ucindezela inkinobho ye-shutter ku-DSLR, isibuko siphuma endaweni, sivumele ukukhanya okuhamba nge-lens ukuze kufinyelele inzwa yesithombe.
Ikhamera ye-lens eguquguqukayo engalazi esibukweni (i-ILC) ayinayo indlela yokubukwa kwesibuko etholakala kwi-DSLR. Ukukhanya kushaya ngokuqhubekayo inzwa yesithombe.
I-Optical Viewfinder Design
Lokhu kuklanywa kwesibuko kushiywe kusukela ezinsukwini ze-SLR zekhamera zamakhamera, lapho noma nini lapho ifilimu ishaywe ukukhanya, izovezwa. Isikrini esibucayi saqinisekisa ukuthi lokhu kuzokwenzeka kuphela lapho umthwebuli wezithombe ecindezela inkinobho ye-shutter. Ngamakhamera adijithali usebenzisa amasitho wesithombe noma kunjalo, isibuko asidingi ngempela kule njongo.
Isibuko sivumela i-DSLR ukuthi isebenzise i-viewfinder ebonakalayo , njengoba isibuko siqondisa ukukhanya okungena ku-lens kuya phezulu nasendleleni yokubukela, okusho ukuthi ungabona ukukhanya kwangempela kusuka esiteshini esibhekene nesikhala. Yingakho ngezinye izikhathi uzozwa i-DSLR "s s optical viewfinder ekhonjiswe njengendlela yokubukwa kwe-lens (TTL).
Ikhamera engenakubukwayo ayisebenzisi i-viewfinder yokubonakala, ngoba ayinayo indlela yokubukwa kwesibuko. Esikhundleni salokho, uma ikhamera engabonakali ihlanganisa isikhangiso, yisibuko sokubuka kagesi (EVF) , okusho ukuthi yisibuko esincane sokubonisa, esibonisa isithombe esifanayo esivela esibukweni sokubukisa ngemuva kwekhamera. Lezi zibuko ezincane zokubonisa esibukweni sokubuka zonke zinamazinga ahlukene wokuxazulula (okusho inani lamaphikseli abasebenzisa ekuboniseni), ngakho abanye abathwebuli bezithombe abathandi abathandi bokubuka amadijithali ngoba kungenzeka ukuthi abanakho ukuxazulula okuphezulu, okubangelwa isithombe sokubuka lokho akubukhali. Kodwa ungakwazi ukubeka idatha ethile mayelana nezilungiselelo zekhamera esibukweni kusibuko sokubukwa kwedijithali, okuyisici esihle.
Ama-Camera Wama-DSLR
Imodeli yekhamera yedijithali ebonakala njenge-DSLR, kodwa lokho akunikezi isitembu sokubukela se-TTL noma ama-lens aguquguqukayo, ngokuvamile okuthiwa ikhamera yesitayela se-DSLR. Kuyinto ikhamera lens fixed , kodwa ine-lens umgogodla omkhulu kanye nomzimba ikhamera enkulu eyenza kubonakale i-DSLR, kokubili design body futhi ngobukhulu nesisindo ikhamera.
Ama-cameras anama-lens agxilile amashadi avamile athambekele ekubeni nekhono elikhulu le-telephoto, ebenza bakwazi ukudubula izithombe ngaphezu kwebanga elide, njenge- Nikon Coolpix P900 kanye ne-83X lens zoom zoom lens. Yize lezi zinkhamera ezinkulu zamehlo zibukeka njenge-DSLRs, abanalo ikhwalithi yesithombe esiphakeme noma amazinga okusebenza okusheshayo ngisho ne-DSLR eyisisekelo kakhulu.
