The Sigma dp2 Quattro should arrive in my hands Saturday morning (tomorrow).]
My initial coverage will take as its priority the Sigma DP2 Merrill vs the dp2 Quattro for resolution, color and dynamic range under controlled conditions. Field work to follow.
This is an exciting camera to me; its sensor holds promise for eclipsing the detail possible with even 22 megapixel DSLRs. Might it emphatically surpass DSLRs like the Canon 5D Mark III? It might even approach the Nikon D800E in real detail. I expect improved image quality and longer battery life over the DP Merrill series.
