Ikhwalithi yesithombe se-digital "amathreyi ensipho" sekuye kwaphela ukumangaza abasebenzisi, ngakho ezandleni zabo, kaningi nakakhulu baqala ukubonakala ngamakhamera we- SLR. Empeleni, ngani? I-Inthanethi igcwele izifundo zevidiyo, izimpawu zidwetshwe kuwo wonke amakhonsela amema ukutadisha ezikoleni ezikhethekile. Uma sibheka lesi simiso, sinikeza umfundi ulwazi oluzosiza uNobhala ukuthi aqonde ukuthi angakhetha kanjani ikhamera yakhe yokuqala ye-SLR kahle.
Ulwazi jikelele
Okokuqala, ake sichaze ukuthi ikhamera ye-SLR yedijithali iyini, bese sibuyela embuzweni wokuthi singayikhetha kanjani. Ama-mirror amakhamera ahluke kulokhu okushiwo ngenhla "amabhokisi ensipho" ngedivayisi yokuvula. Kulesi sigaba semishini, iqukethe i-lens, isibuko nesiboniso. Ngesikhathi sokucindezela inkinobho ye-trigger, isibuko sikhuphuka ngokushesha, ukukhanya kungena ku-matrix, kudlulisela kuyo isithombe esitholwe ngumbonisi wezithombe ngesikhathi sokucindezela. Kungenxa yobukhona besibuko esifundeni sokukhanya ukuthi lolu hlobo lwekhamera luthiwa igama layo.
Kunombono oqinile wokuthi amakhamera we-SLR anzima kakhulu ukuyisebenzisa, futhi ngokwengxenye lokhu kuyiqiniso. Noma kunjalo, akuwona wonke amadivaysi athunyelwe azinzima kakhulu ekuphathweni. Ngaphambi kokukhetha ikhamera ye-SLR, kufanele uqonde ukuthi ihlukaniswe yaba yi-professional-professional, professional and amateur. Uma kufanele ubhekane namakhamera wezinga eliphezulu lobuchwepheshe isikhathi eside, futhi akuyona iqiniso lokuthi wonke umuntu uzokwazi ukwenza, inguqulo ye-amateur ngeke ibe nzima nakakhulu kunokusebenzisa ibhokisi lesipho ngokwayo.
Khetha ikhamera
Ngakho-ke, ake sibone ukuthi ungakhetha kanjani ikhamera eyi- SLR ehloniphekile. Okokuqala, umculi wezithombe ozayo ochwepheshe kufanele aqonde ukuthi ikakhulukazi ikhwalithi yesithombe ithinteka yizandla, hhayi inani lama-megapixels. Ngakho-ke, akudingekile ukukhetha amadivaysi enenani elingaphezulu kuka-10-14 Mp. Konke okungaphezulu, ezinsukwini zokuqala kuyinkunkuma yemali. Ukuze uqonde, isinqumo sama-megapixel angu-14 sikwanele ukudubula isithombe ubukhulu bebhodibhodi.
Ipharamitha elandelayo, engenalwazi kubasebenzisi, i-transmission yokukhanya (ekhonjiswe kuma-ISO amayunithi). Ukuze uchaze umfundi ukuthi leli xabiso alisizo ukwenza izithombe ezingcono, kuzodingeka isihloko esihlukile. Sizosho nje ukuthi: lapha, okubaluleke nakakhulu ukuqonda kahle izimiso zokukhetha ukukhanyisa kwesihloko kanye nombuso, hhayi ngeyunithi ye-ISO. Ngakho-ke, ukuxosha leli xabiso akufanelekile, akusizi ngalutho ngaphandle kokuba namakhono ezithombeni. Kodwa ubukhulu be-matrix yekhamera - lena ipharamitha ebalulekile! Nakhu kuyadingeka ukuthi ubuze umdayisi-umthengisi mayelana nekhamera lapho likhulu khona. Kulokhu, konke kungokwemvelo - ubukhulu bayo obukhulu, isithombe esicacile futhi esicacile sizovela. Okulandelayo, qaphela ukuphindaphindiwe kokusondeza kwe-optical ne-optical kuphela!
I-zoom yedijithali, iningi labakhiqizi abaziqhayisa, alikholi ngempela, kodwa kwandisa kuphela ingxenye yefreyimu yomthwebuli wezithombe, ngenkathi kunciphisa ikhwalithi yesithombe. Kodwa ukusondeza kwe-optical njenge-binocular kwenza isithombe siseduze, ngaphandle kokulahlekelwa njengesithombe. Okulandelayo, qiniseka ukuthi unake umthamo omkhulu wememori khadi esekelwe, kufanele kube okungenani i-32 GB, nokuningi - okungcono! Futhi, zama ukukhetha imodeli ezoba lula ukulala ezandleni zakho, ngoba akusiyo umthengisi, okungukuthi wena, umthwebuli wezithombe zesikhathi esizayo, ukwakha izithombe zobuciko nale khamera!
Sithemba ukuthi le ndaba izosiza umfundi ukuba akhethe isampula efanelekayo yekhamera ye-SLR.
