I-Nikon Speedlight SB-900 Flash Review
Le yi-Nikon's flagship flashgun, kwaye ineetoni zezinto ezixhomekeke kuyo. Nangona kunjalo, likhulu kakhulu kwaye liya kuthatha indawo eninzi kwigumbi lakho lekhamera!
Kufuneka kwakhona uqaphele ukuba kuya kusebenza kuphela ekusebenzeni ngokupheleleyo kunye neekhamera zedijithali zanamhlanje (D7100, D810, D600, D7000, D90, D60 - khangela iwebhusayithi ye-Nikon yoluhlu olupheleleyo). Iimodeli zekhamera ezindala (ezifana ne-D100, D1, D1X, kunye ne-D1H) ziya kugqitywa kwindlela esetyenziswayo.
Ulawulo kunye namaBhetri
I-Nikon SB-900 igcina ukulawula okuncedo ukufumana imbuyekezo yokuhlawulela , kunye nebhetri igumbi lenziwe kakuhle kwaye liqinile, kunye nemigaqo ecacileyo malunga nendlela yokufaka ibhetri. Nangona kunjalo, i-LCD yesikrini siyancipha, kwaye ezinye iinombolo zinokuba nzima ukuzifunda njengoko zincinci.
Akukho mitha yebhethri, ngoko iibhetri ziya kufa ngaphandle kwesixwayiso. Kodwa ixesha lokuphinda liphindwe ngokukhawuleza ... ngokukhawuleza kakhulu kunama-flashguns angabizi kangako.
Intloko ye-Flash
I-SB-900 ihlanganisa uluhlu oluphawulekayo lwe-17-200mm, ukuya kwi-14mm nge-broad-angle diffuser. Nangona kunjalo, kufuneka kuqatshelwe ukuba kwi-200mm, i-SB-900 kuphela inika i-1/3 inzuzo ngaphezu kwe-85mm yokubeka kwe-SB-600 yakwa-Nikon ubudala. Ngoko, uluhlu olukhulu aluyi kukunika inani elikhulu lokukhanya nokukhawuleza.
Njengomlingani wayo weCanon, i-580EX II, intloko ye-SB-900 inikezela ngokugqibeleleyo kwe-360 degener and pupage coverage, okumele ikushiye ingenanto evulekileyo.
Iyini Inombolo Yesikhokelo?
Siye sathetha malunga nendlela iSB-900 inesibalo solawulo esingama-48m (157.5 inyawo). Kodwa le nto iguqulela ngayo ngokufanelekileyo?
Inombolo yesikhokelo ilandela le fomyula:
| Isikhokelo Inombolo / Ukuvula kwi- ISO 100 = Ubude |
Ukudubula ngo-f / 8, siza kwahlula inombolo yesikhokelo ngokuvula ukucacisa umgama ofanelekileyo kwisifundo:
| 157.5 inyawo / f8 = 19.68 inyawo |
Ngoko ke, ukuba siphezulu kwi-f / 8, izifundo zethu akufanele zibe ngaphezu kwe-19.68 iinyawo kude nombane.
Lo mgama omkhulu kwaye kufuneka ufikele iimeko ezigqibeleleyo! Nangona kunjalo, i-4 foot feet ngaphantsi kwe-Canon ye-580EX II iya kugubungela.
Iimodeli kunye neziHlomelo
I-SB-900 iquka indlela ye-Nikon ye-I-TTL yokuchazwa kwe-flash mode yokumisela eyindlela yokuzenzekelayo. Kugqwesileyo, nje ngokuba usebenzisa ikhamera ehambelanayo. I-flashgun inokufumanisa ukuba usebenzisa i-FX (uhlahlo olupheleleyo) okanye i-DX ( isitimu sesakhelo ) ikhamera.
Kukho ukukhutshwa kwemoto, incwadana, incwadana ebalulekileyo yokuhamba, ukuphindaphinda i-flash, kunye neendlela ezingekho ngeTTL. Imodi yendlela yokubaluleka ebanga eliqhelekileyo inengqiqo, njengoko ubeka ukuvula kunye nomgama wesifundo, kwaye i-flashgun iya kusebenza ukuba ungakanani amandla okuwasebenzisa.
Imodi ye-flash manual ingalawulwa ngo-1/3 ukunyuka kwi-f / 1.4 ukuya kwi-f / 90, kodwa ihlazo lokuba ayikwazi ukuhla ukuya kwi-f1.2.
I-SB-900 iphinda ifike kunye nezihlunu ezibalulekileyo, enye yokukhanyisa i-tungsten kunye ne-fluorescent. Oku kusebenza kakuhle kwaye banceda ukuvelisa imifanekiso eqhotyoshelweyo (kunye nolwazi oludluliselwa kwizakhelo ezimhlophe zekhamera). I-flash ingazijonga ngokuzenzekelayo ukuba yiyiphi ihluzi ekhoyo.
Iipateni zokukhanyisa
I-SB-900 inikezela iipatheni zokukhanyisa ezahlukeneyo ezahlukeneyo: umgangatho, kunye, kunye nobunzima beziko. Okubalulekileyo, ezi zizama ukuguqula amanqaku okulahla kwefayili.
'Kwanjalo' isasaza indawo ehlayo ngokubanzi ngaphaya kwephethini eliqhelekileyo, ngelixa 'i-center-weighed' igxininisa ukukhanya kwinqanaba lomfanekiso. Andiqinisekanga ngokupheleleyo ukuba benza umlinganiselo omkhulu wemeko, kodwa kukho ukuguqulwa okufihlakeleyo okumele kube khona.
Imoya engenantambo
I-Nikon SB-900 isebenza njengenkosi okanye inxalenye yecandelo, kwaye isebenza nabathumeli abangenazintambo. Ukusebenzisa i-flash off-camera kuya kunceda ukunciphisa ukukhanya okukhanyelayo nokukhusela imifanekiso yakho ekujongeni i-flat.
Ukuququmbela
I-SB-900 iyimbonakalo ekhangayo, kunye nezixhobo zayo (ngesimo seklasi yokucoca kunye ne-Sto-fen-type diffuser) zibhetele kangcono kunezo zabalandeli. Nangona kunjalo, ngaphandle kokuba uqhube imitshato emininzi okanye iziganeko, andinakukubona ukuthenga okuyimfuneko xa kuthelekiswa ne-SB-700 engancinci, okanye nakwi-SB-600 emdala.
I-flashgun ebalulekileyo (ngaphandle kwezinto ezimbalwa ezithintekayo), kodwa kubiza kwaye kunzima. Ukuba udinga uluhlu olongezelelweyo kunye nemimiselo enikezelwe yiyo, ke, ndingayincoma ngaphandle kokungabaza.
