IS has nothing to do with focus. It simply moves the image around on the sensor to compensate for lens movement, as determined by internal aceleration sensors.


CA is a problem anytime you have a non-flat piece of glass. It is the same reason prisms can split light into a spectrum.

"The lack of sharp focus makes me think the IS isn't working."


That is really is no indication.  IS doesn't make a lens any sharper. It makes you sharper.  I believe your only recourse is to have someone, Canon, check it out as you will always think something is wrong even if it isn't.

EOS 1DX and 1D Mk IV, even less and less other stuff.
