Tamron 300mm f5.6 model CT-300 in m42 - desert bird

[ramcewan]

This is my travel 300mm. Didn't get much chance to use it while visiting the desert southwest but did capture this bird in a tree with it. Added some contrast and sharpening in pp.

p.s. seems I have some CA around the branches, not sure how best to remove this, I have GIMP and Olympus viewer to pp with, suggestions welcome.

I remove CA in Nikon's raw converter View NX2. The raw converter that came with your camera should be able to remove it. I don't know about GIMP though.
