My understanding is that some sharpening is performed in the camera. As default this is set to "neutral" which must mean "some sharpening" with the alternatives being "weak", presumably no sharpening, or "strong", more sharpening. I have been unable to discover whether this only applies to JPEG images, or is also used for RAW files, though I cannot see why this would be needed.
So, which is preferable:
(1) to set this to "weak" and use software sharpening after downloading to the PC, on the basis of having as "pure" an image as possible in the first instance, or
(2) use the in-camera sharpening routine?
So far, I have left it set to "neutral", and I think I can see minimal sharpening artefacts in my images (large, fine JPEGs) when viewed in Photoshop.
Your opinions, experience, or evidence would be welcome!
