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.
