Ukukhanya okusheshayo okunamandla kumfaki wezithombe ezibucayi
Uchungechunge lwe-SB-900 lungaphezulu kwebanga le- flashgun lika-Nikon futhi liqukethe ezinye izinqamuleli ezinamandla kakhulu. Lolu chungechunge lugcwele ngokugcwele izinsimbi kanye namacilongo, kodwa ingabe kufanelekile ukukhokha okungeziwe ukuze uthenge le flash phezu kweSB-700 eshibhile?
Isibuyekezo sika-2015: I-SB-900 AF Speedlight yaqala ukukhishwa ngo-2008 futhi isuliwe. Isatholakala kumakethe asetshenzisiwe futhi iyinhlangano enkulu ye-flash. I-SB-910 ishintshile le model.
I-Nikon Speedlight SB-900 Flash Review
Lokhu kuyi-flashgun ye-Nikon's flagship, futhi inezinhlamvu zezici ezixhunywe kuyo. Kodwa-ke, kukhulu kakhulu futhi kuzothatha indawo enkulu esikhwameni sakho sekhamera!
Kumele futhi uqaphele ukuthi kuzosebenza kuphela ekusebenzeni okugcwele ngamakhamera wezedijithali zanamuhla (D7100, D810, D600, D7000, D90, D60 - bheka iwebhusayithi ye-Nikon ohlwini oluphelele). Amamodeli akhamera asekhamera (njenge-D100, D1, D1X, ne-D1H) azokhawulelwa ekusetshenzisweni komsebenzisi.
Izilawuli nama-Battery
I-Nikon SB-900 igcina izilawuli eziwusizo zokufinyelela isinxephezelo sokutholakala, futhi igumbi lebhethri lenziwe kahle futhi liqinile, nemiyalelo ecacile yokufaka amabhethri. Kodwa-ke, isikrini se-LCD sincane, kanti ezinye izinombolo zingase kube nzima ukufunda njengoba zincane kakhulu.
Ayikho imitha yebhethri, ngakho amabhethri angafa ngaphandle kokuxwayiswa. Kodwa isikhathi sokuvuselela siyashesha ... ngokushesha kakhulu kunama-flashguns eshibhile ka-Nikon.
I-Flash Head
I-SB-900 ihlanganisa uhla oluphawulekayo lwe-17-200mm, phansi kwe-14mm ne-broad-angle diffuser. Kodwa-ke, kufanele kuqashelwe ukuthi ku-200mm, i-SB-900 kuphela inika inzuzo ye-1/3 ngaphezu kwesimo se-85mm se-SB-600 endala ka-Nikon. Ngakho, ububanzi obuningi ngeke bukunike inani elikhulu lokukhanyisa okungeziwe nokuhlanganisa.
Njengomlingani wayo we-Canon, i-580EX II, ikhanda le-SB-900 linikeza ukugcwalisa okuphelele okungu-360 degree nokuhamba okuhambayo, okumele kukushiye ungatholi lutho.
Iyini Inombolo Yokuqondisa?
Sixoxe ngokuthi i-SB-900 inenombolo yomhlahlandlela wama-48m (157.5 amamitha). Kodwa lokhu kuhumusha kanjani ngemibandela?
Inombolo yomhlahlandlela ilandela le fomula:
| Inombolo Yokuqondisa / Ukuvula ku- ISO 100 = Ubude |
Ukudubula ngo-f / 8, sizohlukanisa inombolo yomhlahlandlela ngokuvula ukuthola ibanga elifanele le ndaba:
| 157.5 izinyawo / f8 = 19.68 amamitha |
Ngakho-ke, uma sidutshulwa ku-f / 8, izihloko zethu akufanele zibe ngaphezu kuka-19.68 amamitha kude ne-flash.
Lona ibanga elide futhi kufanele limboze ukuphela kokugcina! Noma kunjalo, ingamamitha amane ngaphansi kwe-Canon ka-580EX II.
Amamodi nezihlungi
I-SB-900 ihlanganisa imodi ye-Nikon ye-I-TTL yokuchaza ukukhanya okuyi-flash mode okuyi-othomathikhi. Kuhle kakhulu, uma nje usebenzisa ikhamera ehambisanayo. I-flashgun ingahlola futhi uma usebenzisa i-FX (uhlaka olugcwele) noma i-DX ( isreyimu yefreyimu ).
Kukhona nokuvula okuzenzakalelayo, ibhukwana, ibanga elibalulekile, okuphindaphindiwe kwe-flash, kanye ne-non-TTL auto modes. Imodi yokubheka ibanga eliphambili ibalulekile kakhulu, njengoba ubeka ukuvula nokuma kwendaba, futhi i-flashgun izosebenza ukuthi ingakanani amandla okuwasebenzisa.
Imodi ye-flash manual ingalawulwa ku-1/3 increments kusuka f / 1.4 kuya f / 90, kodwa kuyihlazo ukuthi ayikwazi ukwehla ku-f1.2.
I-SB-900 iphinda ifike nezihlungi ezimbili eziwusizo, enye yokukhanyisa kwe-tungsten kanye neyodwa ye-fluorescent. Lezi zisebenza kahle futhi zisiza ukukhiqiza izithombe ezikhanyisiwe (ngolwazi oludluliselwa ezilungiselelweni ezimhlophe zekhamera). I-flash ingahlola ngokuzenzakalelayo ukuthi yikuphi ukuhlunga okukhona.
Ama-Patterns okukhanyisa
I-SB-900 inikeza imibono emithathu yokukhanyisa: izinga elijwayelekile, ngisho, futhi eliphakathi kwesisindo. Okuyisisekelo, lezi zizama ukushintsha amaphuzu okudonsa phansi kwe-flash.
'Ngisho' isakaza izindawo zokudonsa ngokubanzi ngokweqile kunephethini ejwayelekile, kanti 'isikhungo esiphakathi' sigxilisa ukukhanya phakathi kwesithombe. Angiqinisekisi ngokuphelele ukuthi benza umehluko omkhulu, kodwa kukhona ukuguqulwa okucashile okufanele kube khona.
Imodi engenantambo
I-Nikon SB-900 isebenza njengenkosi noma isigqila, futhi isebenza nabathumeli abangenantambo. Ukusebenzisa i-flash off-ikhamera kuzosiza ukunciphisa ukukhanyisa okunzima nokuvimbela izithombe zakho ekubhekeni flat.
Ekuphetheni
I-SB-900 iyi-flashgun ehlaba umxhwele, futhi izesekeli zayo (ngokuma isitifiketi sokuhlunga kanye ne-Sto-fen-type diffuser) zingcono kakhulu kunezo zabalandeli bayo. Kodwa-ke, ngaphandle kokuthi udule imishado eminingi noma imicimbi, angikwazi ukuthenga okudingekayo uma kuqhathaniswa neSB-700 eshibhile, noma ngisho ne-SB-600 endala.
Kuyinto i-flashgun enhle (ngaphandle kokushiyeka okuncane kancane), kodwa kubiza futhi kunzima. Uma udinga ububanzi obengeziwe nezici ezinikezwe yilo, noma kunjalo, ngingayincoma ngaphandle kokungabaza.
