Also, if possible, it would be nice to have a sensor mapping facility to detect and conceal sensor spots (stuck, bright or dead pixels) or even extend it to include dust spots etc and remove them from images automatically.
Additionally, for long exposure pictures it may be nice to have the facility to see the image "develop" on screen as the picture is exposed. The shot can then be stopped as soon as the exposure is optimum.
I may be wrong but I think both of these features are avaiable on Olympus cameras.
