ZS100 + DxO PhotoLab = good/quick combination
For your viewing pleasure, I have three image sets, the back of my house shot raw, processed by DxO PhotoLab at default settings, at wide (25mm equiv.), medium (126mm) and long (250mm) zoom settings.
Each set consists of two images, one resized full scene and one a 100% crop. The full scene demonstrates the vignette and geometry correction, and the 100% crop shows the sharpening/optical correction. There's other stuff going on, such as highlight/shadow, but these images should give you a pretty good idea of he software capability.
I can obtain equally good results from ACR/Lightroom, but it takes (much) more work. PhotoLab seems to have hit the sweet spot of really good correction at default settings. BTW also good results for jpeg.
