Strange edge artifacts

I noticed very strange problems while logging the footage I shot recently with my DVX100B and Letus Economy adapter. On the attached picture it looks like the green 'fringing' at the edge of the dune (this is not actual fringing, of course). I wonder what's the reason for this. (I'm as green as this artifact ;). I've never seen such severe artifacts before. It seems to be too thick to be chroma-subsampling related, I guess (I was shooting 16x9 squeeze, 4:2:0 chroma - PAL). Any ideas?

Now that I think it over I guess it might have been my Canon FD 50mm/1.4 lens which was wide open. It's quite fuzzy at f 1.4 and gets sharp at >=f 2.8...
