I think it might be the axial chromatic aberration.

Thanks for your help!

As I mentioned in my earlier post, axial chromatic aberration can be reduced by using a smaller aperture (numerically larger f-number.) Try to recreate the effect, and see if changing the aperture varies the effect. Also, if you have another lens, try using it to captuer the same effect. It's highly unlikely that two different lenses would produce the same effect under the same circumstances.

Without being rude to you or your parents, I can understand their reluctance, esp where they may not [yet] fully understand the benefits that can be obtained from sharing

Maybe if you put this post [DonalDuc's] "NEX and Tamron 18-200" on the screen and show them his beautiful images, maybe they will become a bit happier about you uploading some of yours ~ esp where you are asking for advice
