The Quattro DP1 is weird looking, I work for the local Sigma distributor so even I find it odd. After seeing some work done on this beastie by Christian Fletcher I decided to give it a run. What I found were files that looked amazing, coming close to or at times better than 35mm sensors however it is not for the faint hearted- you really need to wrangle the sigma software to achieve the best result and its not all that easy or fast. Sigma, you really need to talk to Adobe.
The most surprising aspect was the vibrant colours, I have never seen such a range of colour come from a sensor to the point where they were so vivid in “vivid” mode that I probably should have de saturated a little, you can see why the landscape guys love this camera.
As a street camera it has the ability to render the finest details an produce wonderful colours but it is a bit slow on the shooting side and low light is not its strong point.
