Ukuphucula iifoto ngokukhetha ilensi efanelekileyo
Ubude obujoliswe kwixesha elibalulekileyo kwiifoto kunye nangenkcazo yalo elula yinkalo yombono wekhamera ethile yekhamera.
Ubungakanani obude bubeka ubungakanani bendawo apho ikhamera ibona. Iyakwazi ukuhluka kwiindawo eziqhelekileyo ezingathatha kwilizwe lonke ukuba zifake iifayili zefowuni ezingasondeza kwisifundo esincinane kumgama.
Xa ukudubula naluphi na uhlobo lwekhamera, kodwa ngokukodwa ikhamera ye- DSLR , kubalulekile ukuba ube nolwazi olufanelekileyo lobungakanani obude. Ngolunye ulwazi olusisiseko, unokhetha ilensi efanelekileyo yesifundo esithile kwaye uya kukwazi ukuba ungalindela nangaphambi kokuba ukhange kwi- viewfinder .
Eli nqaku liyakunceda uqonde ubude obude kwaye uchaze ukubaluleka kobude obuphambili kwizithombe zedijithali.
Yintoni ekujoliswe kuyo?
Nantsi inzululwazi inkcazo yobude obude: Xa ukukhanya kwimibala efana nendawo iqhuma i-lens igxininise ekungaphelelweni, iya guquka ibe yindawo ephambili. Ubude obude beli lens lide ukusuka emkhatsini we-lens ukuya kweli nqaku.
Ubude obude be-lens buza kuboniswa kumbhobho we-lens.
Iintlobo zamaLensi
Iilensi zihlala zihlulwe njengendawo ebanzi, i- standard (okanye evamile), okanye i- telephoto . Ubungakanani obude beli lens luchaza i-angle yeembono, ngoko-ke i-lens wide-angle ine-small focal length, ngelixa i-telephoto lens ibe nobude obukhulu.
Nalu uluhlu lweenkcukacha ezide ezijoliswe kwiinkalo zelensi:
- Ngaphantsi kwama-21mm: I-lens enkulu ye-angle-angle
- 21-35mm: I-lens-angle angle
- 35-70mm: I-lens Standard / Normal
- 70-135mm: I-Telephoto ephezulu
- 135-300mm (okanye ngaphezulu): i-Telephoto
Zoom vs Premier Lenses
Kukho ezimbini iintlobo zama-lens: i-prime (okanye i-fixed) kunye ne-zoom.
- I-lens prime iya kuba nobude obude kuphela (umz. 50mm).
- I-zoom lens iya kubandakanya uluhlu lweendawo eziphambili (umz. 17-40mm).
Zoom Lens Benevantages
I-lens ye-Zoom ikulungele ukuba unokutshintsha ngokukhawuleza ubude obujolise kwi-viewfinder kwaye awunayo inqwelo yekhamera egcwele iilensi. Abaninzi bezithombe zedijithali zedijithali banokungena kunye neelensi ezimbini zetekisi ezifakela uluhlu olupheleleyo lwamaxesha abude.
Enye into ekufuneka uyiqwalasele, nangona kunjalo, yintoni inkulu yelolu hlobo olufunayo kwi-zoom lens eyodwa. Zininzi iilensi ezihamba ukusuka kwi-24mm ukuya kwi-300mm (kwaye naphi na phakathi) kwaye ezi zilungeleke kakhulu.
Umba uvame ukuphakama kweglasi kulezi lense ngenxa yokubanzi kwoluhlu, ezinye iinkalo ukukhanya kufuneka kuhambe ngazo. Ukuba unomdla kwelinye lala lensi yee-lens eziguqukayo kwaye ufuna ukulungiswa komgangatho wesithombe, kungcono ukuba uchithe imali ethe xaxa kwilensi ephezulu.
I-Prime Lens Benevantages
Iimali zentloko zizinzuzo ezimbini ezibalulekileyo: umgangatho kunye nekhawulezi.
Ngokukhawuleza, sithetha ngokugqithwa ngokubanzi (f / stop) ekwakhiwe kwilensi. Kwinqanaba elincinane (inombolo encinci, ukuvula ngokubanzi), unokufakela umfanekiso ekukhanyeni okuphantsi kwaye usetyenzise ukukhawuleza ngokukhawuleza ukuvala isenzo. Yingakho i / f / 1.8 yinto ekhangayo kwiilensi. I-lens ye-Zoom ayifumaneki ngokukhawuleza kwaye ukuba yenzayo, iyabiza kakhulu.
I-prime lens ilula kakhulu ekwakheni kunokuba i-zoom lens kuba kukho izinto ezimbalwa zeglasi ngaphakathi kwimizila kwaye akudingeki ukuba zihambele ukuguqula ubude obude. Ingilazi encinane yokuhamba ngeendlela kuthetha ukuba ithuba elincinci lokuphazamiseka kwaye kaninzi linikeza umfanekiso ogqithisileyo kunye ocacileyo.
Umgca wokuGqwesa
Ubude obude beelensi babuye babuyiselwa kwimini yefayili yefestile kwaye ihambelana nobude obude beli lens kwikhamera ye-35mm. (Hlalani nikhumbule, nangona kunjalo, loo 35mm ibhekisela kuhlobo lwefilimu elisetyenzisiweyo kwaye akulona ubude obude!) Ukuba unenhlanhla ngokwaneleyo ukuba ube nesinye sezikhundla ze-DSLRs ezipheleleyo, ubude bakho buza kuba buchaphazelekayo.
Ukuba kunjalo ke, usebenzisa isakhelo sesityalo (APS-C) ikhamera, ngoko ubude bakho obude buya kuthinteka. Ngenxa yokuba izixhobo zentsimbi zezityalo zincinci kunomgca we-35mm wefilimu, ukunyusa kufuneka kusetyenziswe. Ukuphakama kuyahlukahluka phakathi kwabavelisi, kodwa umgangatho x1.6. I-Canon isebenzisa ukukhushulwa, kodwa i-Nikon isebenzisa i-x1.5 ne-Olympus isebenzisa i-x2.
Ngokomzekelo, kwikhamera yefowuni yeCanon , i-lens standard 50mm iba ngumlingo we-telephoto 80mm. (50mm yanda nge-1.6 yefuthe kwi-80mm.)
Abaninzi abenzi benzi ngoku benza iilensi ezivumela ukukhushulwa, okusebenza kuphela kwiikhamera zesityalo. Oku kunceda kakhulu ekupheleni kwezinto, apho ukuphakanyiswa kunokuguqula ezi iilensi zibe ziqhelekileyo!
