Eia nō naʻe, ʻo Sigma DP3 kahi pahupaʻiwikiō paʻa piha i loko o ke kino like me kona mau kaikaina.

ʻAʻole ka sensor he 46 MP hoʻokahi maoli ia, akā ʻekolu mau ʻanuʻu 15.4 MP ʻokoʻa i hoʻonohonoho ʻia ma luna o kekahi. Hōʻike ka mea ʻikepili ʻo Foveon X3 i ʻekolu mau pale kiʻi paʻi kiʻi ʻokoʻa no kēlā me kēia kala mua. Hāʻawi kēia i nā puka puka waihoʻoluʻu maikaʻi a me ka ʻike nui o ka mālamalama. Eia kekahi, ʻo ka hoʻohana ʻana o ʻelua mau kiʻi kiʻi ʻoiaʻiʻo TRUE (Three-layer Responsive Ultimate Engine) II i ka maikaʻi o nā kiʻi.

Hāʻawi ka maka aniani kiʻi kikowaena, mai kahi mamao kau palena iki o 22.6 cm me a 1: lākiō hoʻonui hoʻonui. Manaʻo lima hāʻawi ʻia pū kekahi, e ʻae ana i ka mea paʻi kiʻi e hoʻohana i ke apo nui i loaʻa ma luna.

ʻO Sigma DP3 kahi pahu hoʻomanaʻo hoʻomanaʻo nui, e hiki ai i ka mea hoʻohana ke kī aku i 7 RAW kiʻi i nā pohā o 4 mōlina i kekona.
