the problems/limitations of digital cameras are known to all of us
what I need to know is which is most easily and efficiently correctable and which is most annoying
1. purple fringing?
2. non accurate color reproduction?
3. barrel distortion?
4. blurriness/lack of sharpness?
5. noise?
what?
which can be easily corrected or avoided? either with some photoshooting technics, or with software editing?
thanks

1, 4 and 5 depend on the severity of the problem. eg: lack of sharpeness (such as introduced by the AA filter) is relatively fixable using available sharpening tools. Out of focus is another problem. The ease of fixing noise depends on how much: noise at 1600 ISO out of something as new as a Canon G9 is going to be a problem - annoyance is in the eye of the beholder, sometimes "grain" can be a good thing. 'normal' fringing is also relatively fixable in todays RAW converters.
2. color balance is easily fixable, assuming RAW and in an ideal world, you have either a neutral gray in the image, or have shot a gray card.
3. slight barrel distortion is probably the easiest to fix. Some of the more exotic lenses have a slight "mustache" distortion that is tougher to fix.
