Tamron Adaptall-2 SP 200-500mm F5.6 (31A) giving me the Blues

I've noticed no difference in the performance of the 31A with or without the drop-in filter. My 65B (400/4) came without the filter so I used the one from my 31A.

Can you point that out, I'm not seeing it.

Zoom in on the tip of the tail, green Fringe on the leFt side red-purple on the right side of the tip. Not really a lot but a little there
