Canon 85 f/1.8 Issue...

[Axys32]

So, recently a friend of mine let me borrow his 85 f/1.8, and it was a fantastic lens, I really enjoyed the shoot. I go back home with the shots, and I start to take a look and instantly notice horrible CA in a few of the shots with high contrast. I was going to see if this kind of CA is common with the lens? After shooting with it for a day, I fell in love with it, and am now really interested in getting one for myself, but if this kind of CA is persistent, I might look into a better alternative.

Any help would be greatly appreciated, thanks guys!
