They (Nikon's lens engineer) deliberately design the (far) red wavelength to be out-of-focus. So while the overall image of the human subject is razor sharp, the skin is not.

Interesting. Now I'm thinking about how to emulate this in Photoshop.

Select only the red channel and try blur would be my thought.

Already tried it -- blurred hair and lashes along with skin

You might be able to get really cleaver and difference the red and green channels to make a mask and only do that to the red channel where there's no green.

That sounds interesting -- probably too involved for me, but interesting.

Thanks
