Fringey Forham St Martin

Took a detour on the way home from work today to try out the full frame F.O.V., could do with getting a wider angle lens but that'll have to wait!

So here the result, but whilst processing the photo in Lightroom i notice the huge amount of Green and Magenta fringing on the lens, any ideas on where to find a good lens profile or the details on how to make one? The lens is pretty old school (ef 28-105mm 1 : 3.5-4.5)

Anyway hope you all had a great halfway day!
