I-Sigma DP3 ijoyina usapho lakwaMerrill

I-DP3 Merrill entsha kaSigma yasungulwa e-CES 2013, inesiphene esifanayo se-MP ye-46 njengabantakwabo.

I-Sigma DP3 Merrill yongeza usapho lakwaMerrill lwe-DP1 kunye ne-DP2.

Ukushicilelwa kukaSigma Ikhamera entsha ipakisha ubungakanani obufanayo be-APS-C 46MP Foveon X3 Merrill Inzwa njengoko ifunyenwe kwiikhamera ze-Sigma DP1 kunye ne-DP2. Inkqubo ye- Iilensi ezingama-50mm f / 2.8 linyathelo elithile lendalo elivela kwi-DP1's 19mm kunye ne-DP2's 30mm lens. Okwangoku, iSigma DP3 yifayile ye- khamera yelensi emileyo ipakishwe kumzimba omnye nabantakwabo.

Inzwa ayisiyiyo eyi-46 MP enye, kodwa zintathu ezahlukileyo ze-15.4 MP ze-sensor-layer ezibekwe ngaphezulu kwenye. Inzwa yeFoveon X3 inezinto ezintathu ezahlukeneyo ezibonisa ukufota kwimibala ephambili. Oku kuthetha ukuba ihambisa ukugqwesa ngombala okugqwesileyo kunye nokuziva okukhulu kokukhanya. Ukusetyenziswa kwe-Injini ezimbini ze-TRUE (ii-Three-layer Responsive Ultimate Engine) ii-processor zemifanekiso II ziphucula umgangatho wemifanekiso.

Iilensi ezingama-50mm 2.8 -zenzelwe ngokukodwa i-DP3-iyazingca ngayo Uyilo lweetelecentric eyalela ukukhanya phantse ngokuthe ngqo kwi-sensor. Inkqubo ye- Ukusasazeka okukhethekileyo okuPhantsi (LTC) iglasi, izinto ze-aspherical kunye Iingubo eziNinzi zoLuhlu yongeza ukunciphisa i-flare, ghosting kunye nokunye ukuphazamiseka kwemifanekiso. Iilensi nazo ziyahambisa Ukufota okukhulu, ukusuka kumgama wobuncinane ekugxilwe kuwo oyi-22.6 cm nge 1: 3 umlinganiselo wokukhulisa. Ukugxila kwizandla inikezelwe ngokunjalo, ivumela umfoti ukuba asebenzise iringi egxile kuyo.

I-Sigma DP3 ine-memory buffer enkulu, eyenza ukuba umsebenzisi adubule aye kuyo 7 RAW imifanekiso Ukuqhuma kweefreyimu ezi-4 ngomzuzwana. Kwezinye iimeko, xa iindlela zomgangatho ophakathi okanye ezisezantsi zinikwe amandla, ukuqhuma kungafikelela phezulu 5 fps ye Ukulandelelana kwemifanekiso eli-14. Imifanekiso inokurekhodwa kuzo zombini RAW kwaye Iifomathi zeJPEG. Kwicala lokugcina, i-DP3 yamkela amakhadi e-SD, i-SDHC kunye ne-SDXC.

Ukubeka esweni u-3 ”kubonakala kufana ne-DP1's kunye neDP2's: i-920,000 amachaphaza e-TFT LCD. Ikhamera ayinaso isibane kodwa inika isihlangu esishushu Ngaphezulu komzimba, wokuncamathisela i-flashgun ezinikeleyo. Eminye imisebenzi yile: Ukuchongwa kobuso AF mode kunye Ukuqala kweShutter AF ukhetho olunqumamisa ukujonga okubukhoma ngokuhamba ngokukhawuleza okukhawulezayo, Indlela yeMuvi evumela umsebenzisi ukuba arekhode i-VGA (640 × 480) iividiyo ezinobungakanani, kunye nesikhokelo Ulawulo lwe-ISO.

I-Sigma DP3 ihambisa i-4fps ngokudubula ngokudubula ngenxa yombini weprosesa yomfanekiso we-TRUE II.

Ixabiso lokuqala okanye umhla wokufumaneka wawungachazwanga ngexesha lokupapashwa kweli nqaku, kodwa sihlala sicinga ukuba iSigma DP3 Merrill iya kubiza imali efanayo nabantakwabo, kwenye indawo ejikeleze $ 1000.
