Re: Interesting colour comparison ...

I should add that I now remember that I was careful to use the same exposure exactly, both f/stop and time. You will see that the hue of the sunlit grass and the blue sky is identical, the tone darker in the W/A shot. The second shot is in effect less exposed: not only had the light altered, which made shadows and other areas both darker and redder, but I suspect that the attachment cut about half a stop of light.

It's notorious that small shifts in the position of clouds in relation to the sun create colour shifts in shadows quite apart from the effect of different light levels.

These two shots are really pretty good for purposes of comparison considering that for the second I had to attach the Nikon firmly and reframe. In any case I wasn't primarily interested in colour consistency, but in checking that the Nikon didn't add other aberrations. The f/stop had to be the same, and no wider than f/8.
