The Nikon Speedlight SB-900 Flash Review
Izi ndizithunzi za Nikon, ndipo zili ndi matani a zizindikiro zake. Komabe, ndizovuta kwambiri ndipo zimatenga malo ambiri mu thumba lanu la kamera!
Muyeneranso kudziwa kuti zidzangogwira ntchito ndi makamera amakono (D7100, D810, D600, D7000, D90, D60 - onani tsamba la Nikon pazenera zonse). Zitsanzo zamakera akale (monga D100, D1, D1X, ndi D1H) zidzakhala zochepa pazogwiritsa ntchito.
Kulamulira ndi Mabatire
Nikon SB-900 imakhala ndi mphamvu zothandizira kupeza mphoto yowonongeka , ndipo chipinda cha batri chimapangidwa bwino komanso cholimba, ndi malangizo omveka a momwe angayikiritse mabatire. Komabe, sewero la LCD ndi losasangalatsa, ndipo nambala zina zingakhale zovuta kuziwerenga pamene ali aang'ono kwambiri.
Palibe mita ya batri, kotero mabatire akhoza kufa popanda chenjezo. Koma kubwezeretsa nthawi mofulumira ... mofulumira mofulumira kusiyana ndi flashguns zotsika mtengo za Nikon.
Mutu wa Flash
SB-900 imaphatikizapo mapiritsi 17-200mm, mpaka 14mm ndi broad-angle diffuser. Komabe, tiyenera kukumbukira kuti pa 200mm, SB-900 imangopereka 1/3 kuyima mwayi pa malo 85mm a SB-600 akale a Nikon. Kotero, mndandanda waukulu sungakupatseni kuchuluka kwowonjezera kwowonjezera ndi kufalitsa.
Mofanana ndi mnzake wina wa Canon, 580EX II, mutu wa SB-900 umapereka mazenera okwana 360 digiri ndipo akuwonekera, zomwe ziyenera kukusiyani popanda kutsegulidwa.
Kodi Nambala Yotsogolera ndi iti?
Tayankhula za momwe SB-900 ili ndi chiwerengero cha 48m (157,5 feet). Koma kodi izi zikutanthauzira bwanji mwakuya?
Nambala yotsatila imatsata izi:
| Tsamba Nambala / Kutsegula pa ISO 100 = Kutalikira |
Kuwombera pa f / 8, tikhoza kugawira nambala yotsogola polemba kuti tipeze mtunda woyenera wa phunziro:
| 157.5 mapazi / f8 = 19.68 mapazi |
Choncho, ngati tikuwombera f / 8, nkhani zathu siziyenera kupitirira 19.68 mapazi kutali ndi kuwala.
Uku ndikutalika kwakukulu ndipo ziyenera kukumbukira zochitika zambiri! Komabe, ndizitali mamita 4 kuposa 580EX II ya Canon.
Miyeso ndi Zowonongeka
SB-900 ikuphatikizapo njira ya Nikon's I-TTL yozengereza kufotokozera njira zomwe zimangokhalapo. Ndibwino kwambiri, malinga ngati mukugwiritsa ntchito kamera yogwirizana. Ntchentche imatha kudziwa ngati mukugwiritsa ntchito FX (full frame) kapena DX ( mbewu frame ) kamera.
Palinso mawonekedwe a magalimoto, buku loyambira, loyambira-kutalika, maulendo obwerezabwereza, ndi osati a TTL. Njira yapamwamba yopangira mapulogalamu ndi yochenjera kwambiri, poika malo ndi mtunda wa phunziro, ndipo flashgun idzagwiritsa ntchito mphamvu yogwiritsira ntchito.
Bukuli likhoza kuyendetsedwa mu 1/3 kuchuluka kwa f / 1.4 mpaka f / 90, koma ndizochititsa manyazi kuti sizingatheke ku f1.2.
SB-900 imabweranso ndi zojambulidwa ziwiri zothandiza, imodzi ya kuwala kwa tungsten ndi imodzi ya fulorosenti. Izi zimagwira ntchito bwino ndipo zimathandizira kupanga zojambula bwino bwino ( ndizofalitsidwa pamakonzedwe oyera a kamera). Kuwala kungathenso kuzindikira kuti fyuluta ili pati.
Zithunzi Zowunikira
SB-900 imapereka njira zitatu zoyeretsera: zofanana, ngakhale, ndi zolemera. Zowonadi, awa amayesa kusintha mfundo zochotsera za flash.
'Ngakhale' imafalitsa mbali zochotsera zochepa kusiyana ndi kachitidwe kachitidwe, pamene 'kulemera kwapakati' kumapangitsa kuwala kukuyambira pakati pa chithunzichi. Sindinakayikire konse kuti amapanga kusiyana kwakukulu, koma pali kusintha kosasunthika komwe kungakhaleko.
Mafilimu opanda waya
Nikon SB-900 imagwira ntchito ngati mbuye kapena kapolo, ndipo imagwira ntchito ndi osayatsira opanda waya. Kugwiritsira ntchito chiwombankhanga kuchotsa makamera kudzakuthandizani kuchepetsa kuunika koopsa ndi kuteteza zithunzi zanu kuti musamawoneke.
Pomaliza
SB-900 ndiwotchi, ndipo zipangizo zake (monga mawonekedwe a fyuluta ndi Sto-fen-mtundu diffuser) zili bwino kuposa zomwe zimapikisana nawo. Komabe, pokhapokha mutaponya maukwati ambiri kapena zochitika, sindikuwona kuti ndizofunika kugula poyerekeza ndi mtengo wotsika SB-700, kapena wachikulire SB-600.
Ndiwotchedwa flashgun yodabwitsa (osati zochepa zokopa pang'ono), koma ndizovuta komanso zolemera. Ngati mukufuna zina ndi zina zomwe zimaperekedwa ndi izo, ndingakulangize popanda kukayikira.
