[Brightcolours]

For some, who want to have the same sharpness across the whole field, even taking into account stopping down, it may be what they want to do.

They then will get substandard results (much like hyper focal distance adepts). The question was if any camera can compensate for field curvature of the lens, and the question then still must be a no. A camera user can do whatever he/she pleases, of course...
