p.1 #1 · Tamron 60mm f2.0 Macro on D600 (or any Nikon FX)
It was a very pleasant surprise when after purchasing my new D600 I found that my Tamron 60mm f2.0 macro, a lens "designed" for DX cameras, is for the most part, or at least how I use the lens, almost completely functional lens on the camera AND when shooting in FX mode.
To summarize:
1) At distances approaching infinity the lens produces an image circle which clearly/completely shades (should we say vignettes?) the corners. However if you crop out the shaded corners the image achieved is still significantly larger than a DX crop. Actually by my estimate, the cropped image when shooting at near infinity distances the lens still provides an image that is roughly 19MP on the D600 or 80% of the frame (as opposed to just under 50% for DX format.
2) At distances that produce 1:10 magnification (~1m or 3') the image produced is a bit larger maybe about 85% of the full frame.
3. At magnification of 1:2 there is almost no shading that can be seen
4) At a magnification of 1:1 the lens completely fills the FX frame, apparently with not detrimental effects to image quality.
I'll need to do much more careful tests to see the actual quality of the corners at 1:1 magnification and FX frame size, but this still makes me very happy since I really like this lens and would not be too excited to replace it. Of course the center of the image (I often crop to include only the central portion of image) remains unchanged on the FX camera -- see last image.
Below are some sample (quite crappy as a matter a fact) images which were shot in a completely sloppy fashion and only to illustrate shading. Lens is wide open, and manually focused (very sloppily) to achieve set distance or magnifications.

Andre,
Not sure if the corners are bad in the 1:2 to 1:1 range -- where it REALLY matters to me. I'll try and do some additional and more careful test in that range and post the results here.
