Hi Joe -
Question for Mark Cassino:
Re:
"My conclusion was that a low resolving lens with low CA and high edge
sharpness - which is what my tests showed the ATX 400 to be - will create
an image with clean edges and a high degree of _apparent_ detail."

Hi Mark,
Here's a robin I shot a few weeks ago.
http://www.photo.net/photodb/photo?photo_id=3095297&size=lg
It's not as sharp as your pic. It's handheld with the a 400/5.6 and the A2X-S
converter at 5.6, 1/500. But you can get some idea of the feather texture. The
branch he's perched on provides
Interesting theory, Mark.
Please report any further findings on this.

I would tend to agree. The "fuzziness" of those "hairs" has be
Mark,

feathers' structure. I used to keep birds (parrots mostly) and
that's what their breast feathers look like when seen close up.
Robins are much the same.

I posted this before (over a year ago), but I think it's an interesting
illustration of what is being discussed in terms of how lenses differ
