I-DSLR, okanye ikhamera ye-lens eyodwa yekhamera yekhamera yinkomfa ephezulu yedijithali yedijithali enika ikhwalithi yezinga eliphezulu eliphezulu, amanqanaba okusebenza kunye nokukhethwa kwindlela yokulawula, ngokubhetele ngakumbi kunokuba ungayifumana nekhamera yelenki ehleliweyo kwi-smartphone. Olu hlobo lwekhamera lisebenzisa iilensi eziguquguqukayo, ngelixa ikhamera yecala ehleliweyo inomlenze owakhiwe kumzimba wekhamera kwaye umfaki-zithombe akakwazi ukutshintsha.
Nangona iifoto zabaphantse ziphantse ziyakuthengi kwaye zisebenzise ikhamera ye-DSLR , ezi ntlobo zeekhamera zilungele abathwebuli bezithombe abanobuchule obuninzi bezithombe zedijithali . Ngenxa yokuba ii-cameras ze-DSLR zingabiza phi na kwiiyure ezili-dollar ukuya kumawaka angamawaka eedola, zilungele ngokufanelekileyo kubathwebuli beefoto abanamava anelungelo lokusebenzisa amathuba abo ekupheleni.
I-DSLR iikhamera Vs. Iikhamera ezingenakuso
Iikhamera ze-DSLR azikho kuphela uhlobo lwekhamera lens eguquguqukayo. Olunye uhlobo lwekhamera ye-lens eguquguqukayo, ebizwa ngekhamera engenzi-mirror, inomxholo othile ongaphakathi we-DSLR.
I-DSLR yekhamera yangaphakathi yekhamera iqukethe isibuko esithintela ukukhanya ekuhambeni kwilensi kunye nokubetha isitho somfanekiso. (Umtshini wesithombe yinkqubo yokukhanya ebonakalayo ngaphakathi kwekhamera yedijithali eyenza ukukhanya kwimeko, okuyiyo isiseko sokudala umfanekiso wesigodi.) Xa ucinezela inkinobho yokuvala kwi-DSLR, isibuko siphuma endaweni, sivumele ukukhanya ukuhamba nge-lens ukufikelela kwisixhobo somfanekiso.
Ikhamera ye-lens engenzi-mirror (ILC) ayinayo i-mirror mechanism efunyenwe kwi-DSLR. Ukukhanya kuqhubela phambili ukushaya umtshini wesithombe.
I-Optical Viewfinder Design
Esi sikhombisi sakhiwo sishiywe ukusuka kwiintsuku ze-SLR zekhamera zefilimu, apho naliphi na ixesha ifilimu yahlaselwa ngokukhanya, yayiza kubonakala. Indlela yokwenza isibuko isiqinisekisile ukuba oku kuza kwenzeka xa umfoto wefotshane ephosa iqhosha lokuvala. Ngeekhamera zedijithali usebenzisa izixhobo zesikrini nangona kunjalo, isibuko asiyifunayo ngokwenene kule njongo.
Isibuko sivumela i-DSLR ukuba isebenzise i-viewfinder ye-optical , njengoko isibuko siphinde sichaze ukukhanya okungena kwi-lens ukuya phezulu nakwindlela yokubukela, oku kuthetha ukuba unokubona ukukhanya okwenziwe kwimeko eyenza i-lens. Yingakho ngezinye izihlandlo uya kuthi uvale i-DSLR "s optical viewfinder ekubhekiselelwe kuyo njengendlela yokubukela i-lens (TTL).
Ikhamera engenzi-mirror ayisebenzisi i-viewfinder ye-optical, ngenxa yokuba ayinayo i-mirror mechanism. Endaweni yoko, ukuba ikhamera engabonakaliyo ibandakanya i-viewfinder, isibhengezo sesiganeko sombane (EVF) , esichazelayo isikrini esincinci, esibonisa umfanekiso ofanayo ovela kwisikrini sokubonisa emva kwekhamera. Ezi ziboniso ezincinci kwi-viewfinder zonke zinamanqanaba ahlukeneyo esisombululo (esithetha inani lamaphikseli abasebenzisa kulo mboniso), ngoko abanye abathandi beefoto abathandi ababukeli bedijithali ngenxa yokuba abanakho isisombululo esiphezulu, okubangela umfanekiso wesibhengezo engacacanga. Kodwa unokwenza idilesi ethile malunga nezicwangciso zekhamera kwisikrini kwisibhengezo sokubonakalisa idijithali, into ebalulekileyo.
Iikhamera Zama-DSLR
Imodeli yekhamera yedijithali ekhangeleka njenge-DSLR, kodwa loo nto ayinikezeli i-TTL okanye i-lens eguquguqukayo, ibizwa ngokuba yi-DSLR-style camera. Ikhefu lekhamera elungisiweyo , kodwa linombhobho omkhulu wecala kunye nomzimba omkhulu wekhamera owenza ukuba kubonakale njenge-DSLR, zombini kwisakhiwo somzimba kunye nobukhulu kunye nobukhulu bekhamera.
Ezi zixhobo ze-DSLR-lens ezifakwe kwi-lens cameras ziba nekhono elikhulu lokwenza i-telephoto, ezivumela ukuba batyeke iifoto kumgama omde, njenge- Nikon Coolpix P900 kunye ne-83X ye-zoom optical lens. Nangona ezi ikhamera zentengiso ezinkulu zibukeka njenge-DSLRs, abanalo uphawu oluphezulu lokugcina umfanekiso okanye amanqanaba okusebenza okukhawuleza ukuba i-DSLR eyona nto ibalulekileyo.
