Did you have any chance comparing ZD files development in Lightroom vs SilkyPix 3.0? So far I use only SilkyPix. I like the ability to max demosaicing sharpness in SilkyPix - takes longer to process, but gives much crisper files than ACR 3.7.
I have tried both lightroom and Silkypix to convert ZD raw files. Silkypix has a huge advantage when converting ZD images of 1 sec and longer reducing visible noise which lightroom has trouble Silkypix is great but slow to convert. If lightroom allows tethered shooting I will definitely use this option for shorter exposure images.
