Ilensi yekhamera ye-DV ye-angle ebanzi
Ilensi yomugqa obanzi:
Uma sithatha ikhamera ye-reflex yelensi eyodwa engu-35mm njengesibonelo, ilensi ye-engeli ebanzi ivamise ukusho ilensi enobude bokugxila obungafinyelela ku-17 kuya ku-35mm.
Isici esiyisisekelo selensi ye-wide-angle ukuthi ilensi ine-engeli enkulu yokubuka kanye nomkhakha obanzi wokubona.Uhlu lwezindawo ezibhekwayo ngokombono othile likhulu kakhulu kunalolo olubonwa ngamehlo abantu ngombono ofanayo;Ukujula kwesigcawu kude, okungabonisa ububanzi obuningi obucacile;Ingagcizelela umphumela wombono wesithombe, ibe muhle ekwenzeni ihaba ngethemba futhi iveze umuzwa webanga kanye nokuba seduze kwendawo yesehlakalo, okusiza ekuthuthukiseni ukukhanga kwesithombe.
Izici eziyisisekelo zamalensi ane-engeli ebanzi:
1. I-engeli yokubuka ebanzi, engamboza ububanzi bendawo.Okubizwa nge-engeli enkulu yokubuka kusho ukuthi indawo yokubuka efanayo (ibanga elisuka esihlokweni lihlala lingashintshiwe) lidutshulwa ngobude bokugxila obuthathu obuhlukene be-engeli ebanzi, evamile kanye ne-telephoto.Ngenxa yalokho, eyokuqala ithatha izigcawu eziningi phezulu, phansi, kwesokunxele nakwesokudla kunezakamuva.Lapho umthwebuli wezithombe engenayo indlela yokuphuma, uma kunzima ukuthatha isithombe esiphelele sesigameko ngelensi evamile engu-50mm (njengezithombe eziqoqiwe zabalingiswa, njll.), angakwazi ukuyixazulula kalula inkinga ngokusebenzisa izici ze-wide- Ilensi ye-engeli enohlu olubanzi lwama-engeli wokubuka.Ngokwengeziwe, isibonelo, ukudubula amasimu amakhulu noma izakhiwo ezinde emadolobheni kungase kuthwebule kuphela ingxenye yesigameko ngelensi evamile, engakwazi ukubonisa ububanzi noma ubude bendawo.Ukudubula ngelensi ene-engeli ebanzi kungabonisa ngempumelelo umfutho ovulekile wesigcawu esikhulu noma ubukhosi bezakhiwo ezifinyelela emafini.
2. Ubude bokugxila obufushane nokujula kwesigcawu eside.Lapho bethwebula izigcawu ezibanzi, abathwebuli bezithombe ngokuvamile bathembela ezicini zobude obufushane bokugxila belensi ye-engeli ebanzi kanye nokujula okude kwesigcawu ukuze balethe sonke isigameko kusuka eduze kuya kude kububanzi bokusebenza okucacile.Ukwengeza, lapho uthwebula nge-lens ene-angle ebanzi, uma imbobo encane isetshenziswa ngesikhathi esifanayo, ukujula kwensimu yesehlakalo kuzoba isikhathi eside.Isibonelo, uma umthwebuli wezithombe esebenzisa ilensi ye-engeli ebanzi engu-28mm ukuze athwebule, kugxilwa esihlokweni esingaba ngu-3M, futhi indawo yokuvula isethelwe ku-F8, bese cishe zonke zingena ekujuleni kwenkundla ukusuka ku-1m ukuya kokungapheli.Kungenxa yezimpawu zalokhu kujula okude kwenkambu ukuthi ilensi ye-engeli ebanzi ivamise ukusetshenziswa ngabathwebuli bezithombe njengelensi yokushutha esheshayo enokuhamba okuqinile.Kwezinye izimo, abathwebuli bezithombe bangaqedela ukuthwebula ngokushesha ngaphandle kokugxila esihlokweni.
3. Ukwazi ukugcizelela ithemba futhi uqokomise ukuqhathanisa phakathi kwekude naseduze.Lokhu okunye ukusebenza okubalulekile kwamalensi ane-engeli ebanzi.Okubizwa ngokuthi ukugcizelela okungaphambili nokugqamisa umehluko phakathi kwekude naseduze kusho ukuthi ilensi ye-engeli ebanzi ingagcizelela umehluko phakathi kokuseduze, okude nokuncane kakhulu kunamanye amalensi.Ngamanye amazwi, izithombe ezithathwe ngelensi ye-engeli ebanzi zinezinto ezinkulu eziseduze nezincane ezikude, okwenza abantu bazizwe sengathi zivule ibanga futhi zikhiqize umphumela wombono onamandla ekuqondeni kokujula.Ikakhulukazi uma uthwebula nge-ultra wide-engeli lens enobude bokugxila obufushane, umthelela wokuseduze nokuncane kakhulu ubaluleke kakhulu.
4. Kungenziwa ihaba futhi kukhubazeke.Ngokuvamile, isihloko senziwa ihaba futhi sikhubazekile, okuwumbono omkhulu ekusetshenzisweni kwelensi ye-engeli ebanzi.Eqinisweni, akukhona ngempela okungathandeki ukuthi isihloko senziwe ihaba ngendlela efanele futhi sikhubazekile.Abathwebuli bezithombe abanolwazi bavame ukusebenzisa amalensi ane-engeli ebanzi ukuze bakhubazeke ngokulingene isihloko futhi bathathe izithombe ezingajwayelekile zezinye izigcawu ezingasho lutho abantu abangazinaki.Kunjalo, ukuvezwa kwehaba kanye nokuguqulwa nge-lens ye-angle ebanzi kufanele kusekelwe ezidingweni zetimu, futhi kuncane futhi kucolise.Kungakhathaliseki ukuthi isihloko siyadingeka noma cha, akwanele ukusebenzisa kabi ihaba kanye nokuguqulwa kwelensi ye-engeli ebanzi futhi ulandele ngokumpumputhe umphumela oyinqaba ngendlela.
Singakwenzela i-OEM, i-ODM, uma uyidinga, sicela usithinte ngomusa, ngiyabonga.
