Thanks Paul and Peter for supplying the information.
Peter,
Regarding the problem of vignetting, I think you have to accept this fact until someday in the future you find another perfect dc in the market. I have already told that vignetting is very serious in Nikon 8400 as it is a super wide angle DC (equivalent to 24mm to 85mm in 35mm format), especially at its wide end. It becomes less serious from mid-zoom onward and happens again at its longest end.
I don't think, exposure is a big problem nowadays as the meter of most DC measures the centre more that the four corners---basically the exposure is acceptable if you adjust the EVs properly after seeing the result . Please bear in mind, for some subjects, vignetting can be a good thing as it can lead the viewer to focus on the interested part. This is the way that we always do in visual art presentation.

In my field experience, Fuji F30 & F31 are the best DC for digiscopic photography in terms of less vignetting effect, Nikon P5100 is the second.
