Ekubeni uye wazibuza loo mbuzo, mhlawumbi sele uthenge i sixhobo kwaye izandla zakho ziselele ukuthatha imifanekiso yokuqala. Kodwa ukuba uthenga umzekelo ofanelekileyo ulula, ngoko kukhethwa kwe-lens ngokwayo kuya kuba nzima. Ukufumana ukhetho olufanelekileyo phakathi kwee-lens zeekhamera ze-SLR, kufuneka uqonde indlela ahluke ngayo, kuba yintoni injongo nganye efanelekileyo, kunye nezixhobo zokudubula.
Iinkcukacha zamalensi kwiinkhamera ze-SLR
Okokuqala, siya kuhamba ngokufutshane kwiiparamitha eziza kubhengezwa ngumenzi ngamnye kumzekelo:
- ubude obude (ubuchule bokukhawulela okanye ukuhamba izinto);
- Ubunzulu bezentsimi (xa umxholo ucacile, yonke into ibonakala iphosakele kufuphi nayo, leyo yinkalo eneenkcukacha ezicacileyo okanye ezingekho ngaphantsi kwezinto zokugxila kunye nobunzulu obufanayo);
- ukukhanya okukhanya (ixabiso layo elikhulu, amathuba amaninzi kufuneka wenze ipempile ephumelelayo nakwiimeko zokuhlwa);
- ukuzinza komfanekiso (eqinisweni, le bhonasi eyongezelelweyo ngendlela yokuhlawulela ukuphazamiseka).
Ziziphi iilensi zeekhamera ze-SLR?
Ewe, kunye neempawu zento yonke icacile, kodwa impendulo yombuzo ngokwawo, asikafumani. Ukuze sondele kancinane kwisisombululo, masihambe ngeentlobo zeelensi zeekhamera ze-SLR. Kukho ezininzi, kodwa ezininzi zisetyenziswa. Ngoko, ziphi iilensi zeekhamera ze-SLR kwaye zeziphi iimpawu nganye:
- Intlanzi. Ukusetyenziswa ngokuqhelekileyo, njengoko ngokuqhelekileyo kulungele kuphela izibhengezo zokudala kunye nezicwangciso. Yiyo kuphela ezo zithombe, xa kubonakala sengathi umfanekiso udibene kwisangqa (kubonakala ngathi umphumo xa ukhangela i-peephole). Ngamanye amaxesha basebenzisa ukutshintshana kwezakhiwo
- I-ultra-wide and angle-wide angle. Kwakhona isisombululo esihle kakhulu kwizithombe zedolophu nakwizakhiwo. Lo mbono unobunzulu obunzulu bomhlaba kwaye wenza ukuba ukwazi ukuthatha imifanekiso ngokukhawuleza kakhulu.
- Umgangatho. Kubonakala ngathi umfoto wezithombe zokuqala kufuneka akhethe i-lens yekhamera ye-SLR, kuba le ndlela ilula. Kodwa "umgangatho" uqwalaselwa
kuphela ngenxa yezinto ezingahambi kakuhle ngombono wakhe. - Phakathi kweentlobo zeelensi zeekhamera ze-SLR zi- telephoto lens , ubude babo obude buqala ukusuka kuma-70 mm. Oku kukulungele kakhulu, ukuba uceba ukudubula indalo kunye neentaka, kulungile kwiifriji, zonke izinto ezikude.
- Iilenti zamacro. Khetha i-lens yalolu hlobo lwekhamera ye-SLR, ezininzi zixazululwa sele zikwazi ukuqonda isicwangciso sokutshintshela imifanekiso, isixeko okanye imvelo. Enyanisweni, lolu hlobo oluncinane lufana ne-microscope encinci elinokukwazi ukudubula izinto ezincinane ngobukhulu obupheleleyo kwaye ubone zonke iinkcukacha ezincinci.
