Since 5 years I've been using Sigma compact cameras with a foveon chip.
You will never find any better MTF for about 500 Euros.
I tested a Phase One iQ180 and a Sigma DP1 Merrill.
Copare the attached meshes...
Of course there are some disadvantages working with the Merrill: To store the RAW data, it takes 15 seconds and the noise is terrible at ISO ratings bigger than 200.
However, I would always take the Merrill for UAV-missions, the Phase One for terrestrial Photogrammetry.
Wow, Is it really that much better? I mean your second screen is so much more clean and noiseless. I heard frightening stories about Merrill needing half a minute to save each file.
Wonder how other Sigma cameras do. DP2 Quattro for example?
