DPP4 vs Lightroom -- There are times when I can coax a better file out of the DPP software than out of LR. Having said that, 95% of my workflow goes through LR. If I know I am going to go with a large print, I try a run through DPP. For production runs and normal prints, LR is, for me, a faster workflow. But DPP4 is free! I treat my Sony files the same way. I may run special ones through Capture One, but 95% just go through LR.
