The S5 Pro is a major improvement over the S3 Pro in its handling and build quality, and it makes for an interesting comparison with the Nikon D200. Definition at a pixel level is certainly no better, but the S5 Pro's tonal rendition is often superior, especially with portraits. Also consider:
This camera is great,i have had one for the past year and i would not part with it.It is especially good for portraits.The screen for viewing back your photos is the poor part,it is not very clear

had been using S3pro for the last 3 years, Some exposure problems was solved, good tonal range, faithful colors, battery life was short, burst rate 3 frames is terrible. autofocus poor ,very slow especially AFS 80-200 2.8ED.
