Chromatic Aberration

[Fliphishermon]

I've got a Canon 17-85 mm EF-S f/4-5.6 IS USM Lens. Have had it for a while and never noticed any problems. Now, suddenly, I seem to be getting a lot of chromatic aberration.

Got me bugged.

Any ideas?

17-85 mm it`s known to have some heavy chromatic aberration at it`s shortest focal length of 17mm...
Don`t have any other ideas though.. try making some test at different focal lengths
