Forums > Back > Canon 300mm F4L IS - Normal CA wide open?
#1
I just purchased the Canon 300mm F4L IS.



I noticed that wide open in high contrast I was seeing a decent amount of purple fringing around edges. Is this normal for this lens? I tested 2 samples and both were new.



Here are some shots;



Wide open - crop of Chase Bank letters in sunlight.
