Looks like you had to PP this a bit to get some details out of it.
It was straight from camera JPG (literally - I was still shooting just JPG in those days, not RAW). I did shoot it with +1 EC, and the image is cropped a bit.
By the way did you switch out your 1.4 mk.2 with a mk.3? Did you notice much difference?
I did go from the 1.4xII to the 1.4xIII, yes. But I never compared them side-by-side on the same lens. Since I was getting the 600 II, I wanted the MkIII for the improved AF with the new supertele lenses, and I used the 1.4xII so rarely that I just sold it after I ordered the 600 II and 1.4xIII.
