Zomwe zatulutsidwa posachedwa zafukula kuti wopanga EOS apitilira ndalamayi ndikuti mafani ake atha kuwona kukhazikitsidwa kwa kamera ya Canon 75-megapixel DSLR mu 2013, yomwe iyenera kumasulidwa koyambirira kwa 2014.

Umboni wina wonena za chipangizochi komanso chithunzi chake chazithunzi watulutsidwa, ndi gwero lodalirika kunena kuti kamera idzakhazikitsidwa ndi sensa ya Bayer multilayer yomwe ili ndi "zithunzi zonse zomwe zingagwiritsidwe ntchito".

Zosefera za Bayer zimakhazikitsidwa pa gridi lalikulu lomwe ladzaza ndi zithunzi zofiira, zobiriwira, komanso zamtambo. Hafu ya iyo ndi yobiriwira, pomwe kotala imasungidwa ku yofiira ndi buluu iliyonse. Ndi mtundu wodziwika bwino wazithunzi ndipo umagwiritsidwa ntchito pazida zambiri zojambula.

Posachedwa, Sigma wakhala akuzungulira ndi mtundu watsopano wotchedwa Foveon X3. Zimakhazikitsidwa ndi zigawo zitatu za photodiode, iliyonse yaiwo imakhala ndi mtundu wina.

Makamera a Sigma DP Merrill kujambula zithunzi pamamegapikseli 46 ndipo amadziwika kuti safuna zosefera zotsutsana ndi zovuta, popeza mitundu yamafuta ndiyosiyana, chifukwa chake ma moiré sadzapangidwa.
