Conclusion: The Sigma SD1 Merrill is built around the uniquely designed image sensor, but a high price, sluggish performance and a time-intensive Raw workflow make it a difficult sell to all but the most devoted Foveon disciples.
Pros: Excellent build quality. High-quality viewfinder. Good control layout. Unique sensor design. Infrared shooting capability.
Cons: Expensive. Sluggish performance. Subpar LCD. Substandard JPG output. Difficult Raw workflow. No video support.
Excerpt: Fast-forward to the beginning of 2012 and what is essentially the very same camera, albeit rebranded as the SD1 Merrill, is available for a fraction of that price – though at £1850 it’s still the most expensive APS-C DSLR on the market by quite a margin.
Pros: Detail and sharpness (at ISO 100), removable IR filter; well matched to serious studio pros using ISO 100 & controlled light
Cons: Expensive; very poor high ISO quality; poor auto white balance; slow processing; no live view; unlikely to meet amateur users’ demands
