Re: Nikon D4s: Bayer processing breakthru?

Deconvolution is a linear filtering process - adaptive in this case.  Any linear filter has a frequency response and the frequency response of the image after processing will be the produce of the image frequency response prior to processing and the filter frequency response. Another words that will impact the entire image hence will not be "artifact free."  The diffraction spread over the entire image might be visually preferable to some observers to strong highlights with detail showing diffraction.  However, there is no free lunch.

"Diffraction reducing technology" is something Fuji have too. I imagine it's a de-convolution routine to reverse the point spread. You can do this with any image if you have the right software and some information about the blur function.

Select de-noising has been that well appreciated by reviewers so far - it seems to create artefacts.
