The wide angle lens
What to look out for
Flaring and ghosting are another common problem with ultra wides such as the 14mm. You will have to consciously be aware of the problem and be on a lookout so when it appears, you can alter the position of the lens just enough so you can avoid the ghosting. Loss of contrast though is something else that can be corrected to some degree in post processing.
