Of course, there are limitations and suggestions for improvements. Long exposures and high ISO settings really do not belong to the strengths of the camera. So I can but live well. A Live View function with a magnifying glass on a folding screen I would wish for macros already. It's already quite cumbersome to wait after triggering the closure of the storage process, then to look at the picture and then move to feel the Focus.
The point deduction but there was for the poor further processing of RAW images. I except the SPP of Sigma not found a RAW converter which can read and process the images. The SPP is slowly running and not stable on my Windows 7. Quick and clean processing workflow I'm not getting back with it.
My summary:
++ Handling
+ Processing
+ Image quality
++ Color illustration
- Noise performance with long-term exposure and ISO above 400
- Live View
