Shot with D70 and Sigma 18-50 f/2.8 fully open. Comparison segments are 100% crops from the pic at upper left corner. This camera/lens combo measures 58 lp/mm MTF30 at center; equal or better than 50mm primes. Children's playground at center have many fine details and large dynamic range. All converters set to default parameters, except for sharpening that was set to none or minimum. Converters used: Bibble Pro 4.2.6 , Raw Magick Lite 0.989b , DxO Optics Pro 3.0 beta , Adobe Photoshop CS2 + ACR 3.1 , Dave Coffin's latest DCRaw, Breeze Browser 2.9 , C1 Pro 3.5.2 , Nikon Capture Editor 4.2.1 , Picasa 2 , Raw PhotoDesk 1.12 , Raw Shooter Essentials 1.1.2 .
Notice that some converters DO have sharpening turned on, sometimes pretty heavy, like PhotoDesk. Sensible, fine pitched sharpening (like in C1) is allmost unnoticed and fools the eye giving the particular converter advantage over sharpening-free converters like DCRaw or RML.
